4 matic mercedes is an additional option for driving a car. Without which you can not do on the road in winter and in conditions of unstable road surface. Mercedes equipped with all-wheel drive will help you get from point A to point B on time, and without resorting to the services of a tow truck in case the car got into a snowfall.

History(I)

4matic works on the principle of distributing the torque of the motor separately to each axis of the machine. The 4matic technology was developed by Mercedes together with Steyr Daimler Pasch, a company that assembled in Austria. Four-wheel steering immediately works in tandem with the automatic transmission. The option is available for sedans, hatchbacks, off-road and commercial vehicles (and).

At the end of 2016, Mercedes Benz launched the 4matic plus system into serial sales. Here it became possible to turn off the 4-wheel drive and connect it only to the 2 rear ones.

History 4 matic consists of 5 successive series. The first prototypes of the 4matic system appeared in 1904 and were tested by Paul Daimler. The first light truck was produced in 1907. The large-scale production of vehicles equipped with 4-wheel steering began in 1951 with the Unimog farm truck.

Officially, 4 matic was introduced by Mercedes in Germany in 1985. This system was installed on Mercedes * * and. The locking center differential sends 30% of the torque to the front axle of the car and 70% to the rear axle of the car. The force of the power unit is divided equally between the 2 rear wheels. The front differential was left unoccupied to increase stability and enhance the vehicle's safety features.

The clutches block the differential, they are hydraulically actuated. The system is controlled by the on-board computer and takes readings from speed sensors, ABS and steering wheel movements.

In the 80s the system worked in three modes

2 differentials disabled
center differential is locked
all differentials are locked

When the brake pedal is pressed on both differentials, the lock is removed. The engine torque transmitted to the axles in a ratio of 30/70 was focused on fast and confident acceleration of the car. Drifting when both pairs of wheels are connected is impossible.

History(II)

In the late 80s, all-wheel drive was available as an option for everyone with diesel and gasoline engines of 2.6 and 3 liters. The second 4matic series has been used on Mercedes in the back since the late 90s. The 4matic mode was complete with an unoccupied differential, the traction control function simulated a locking center differential. The ETS system controlled traction control. Only left-hand drive vehicles were equipped with the ETC function.

The third variation of the 4matic mode appeared in 2002, and was introduced for bodies, and. The on-board computer controlled directional stability and controlled traction. The fourth version of the 4-matic system has been installed on cars since 2006.

In 2014, the latest generation of all-wheel drive was used for the first time on models

CLA 45
GL500

The drive is not permanent, but connected as needed, which significantly reduces fuel consumption by almost 18%.
The body-mounted 4matic plus system consists of an electrically operated multi-disc clutch that cuts off power pressure on the front wheelset when needed.

How 4matic works

4matic mode is designed for uncompromising driving on snow, sand, ice and gravel. When used, roll is reduced when cornering. Acceleration picks up faster and there is enough engine power to tow a trailer or other car. The ESP system and the powertrain traction control function work as auxiliary elements of the all-wheel drive.

Torque distribution by the ETC program is guided by sensor data:

ABS (traction control system)
functions to maintain a constant speed when descending a mountain

It then distributes the force to each wheel separately in unstable road conditions.

Episode 3

The 3-series all-wheel drive distributes torque for sedans and light SUVs at a ratio of 40 to the front wheelset and 60% of the torque to the rear. For SUVs 50 to 50. For business class and commercial vehicles 45 to 55. For sedans 33 to 67.

The 4matic 3 series system works in tandem with: an automatic transmission, a cardan shaft that distributes its force to the front of the car, a transfer case, the transmission of the force of the cardan shaft to the rear wheelset, first gear, front and rear between the wheel differential, rear two wheel axles.

The transfer case performs the main function in the Mercedes-Benz all-wheel drive system, it distributes the necessary torque force of the vehicle's power unit. It controls the gearbox, which acts as an asymmetric center differential, gears in the form of cylinders, and drive shafts. The gearbox works in tandem with the drive shaft. The rear shaft is driven by a sun gear. The front shaft is empty inside. It works in tandem with a smaller sun gear and is connected to the driveshaft of the front axle.

Episode 4

4 series 4 matic functions together with a cylindrical differential, it is blocked by a friction clutch with two discs. The distribution of engine torque is 45% to the front axle and 55% to the rear. When picking up speed with a car passing through an icy road. The locking of the center differential is carried out by a friction clutch, which aligns and stabilizes the body of the Mercedes.

The clutch can slip in turns if the difference in the differentials of the front and rear axles of the machine exceeds 45 Nm / metres. Tires do not grind the road surface. Such control during this period performs the 4ETC function by means of pressure on the brake discs.

Stabilization functions:

in the management of the Mercedes body in critical situations, they add torque to the power unit. The 4th generation of all-wheel drive was first installed on a Mercedes body.

Episode 5

5 series all-wheel drive is paired with a motor mounted in the hood across. 4 matic of the fifth series is connected only when necessary (which significantly saves fuel). If a front axle drive is enough for a Mercedes to pass a certain section, then there is no rationality in using the entire drive. When the wheels slip, the control system for all 4 wheels is immediately connected at the same time. As soon as the car has stabilized, the electric drive cuts off the transmission of torque to the rear wheels. All-wheel drive stabilizes the body roll of the car before the ESP and 4ETS auxiliary systems intervene.

The PTU control unit adds power to the rear wheelset. It is part of the automatic transmission 7-G tronic with dual wet clutch. This block is small in size, due to this, the total weight of the car has decreased. In the absence of critical and emergency situations, the torque is distributed along the axes in half.

When picking up speed 60/40
winding road 50/50
loss of grip with the road surface of the front wheelset 10/90
during emergency braking 100/0

So what exactly is 4matic?

This all-wheel drive system improves driving stability under all driving conditions and road conditions, even in the event of an accident. But you need to remember all the time that even the smartest additional option to control the sporty character of the car with unloading the driver in daily and critical situations. With big pluses in the safety of the car. With extra traction and driving stability on unstable road surfaces. 4 the matic cannot go beyond the physical boundaries.

YouTube video:

I continue to talk about incomprehensible abbreviations on various car models, and it just so happened that this detailed article will be about Mercedes (in the first they talked about the compressor). However, today we will talk about such a concept as 4 MATIC. Such an inscription can be found on some modifications of the concern, for example GL, ML, and even on the C-class. So does this mean and why is it applied to the body? Read more…

Let's start with a little definition.

4 MATIC (Firmatic) is the designation of all-wheel drive on Mercedes cars. If you decipher this inscription, it turns out - 4 Wheel Drive and Automatic - 4-wheel drive and automatic transmission.

As you can see, this is almost the designation 4 X 4 on our domestic cars, with the only difference being that an automatic transmission is used, while for Mercedes it can be a torque converter automatic or a robot.

Three generations of 4MATIC

AT the dawn of the appearance of this system, and it was in 1986, the joint engineers of Mercedes-Benz and Steyr-Daimler-Puch, the first generation of this drive was invented.

First generation

It was first installed on the W124 model (modern E-class), it was here that all-wheel drive and automatic were first used. It should be noted that there was no permanent all-wheel drive, but there was a so-called "plug-in". All 4 wheels were switched on by locking the center and rear axle differentials. But the electronics of the first generation 4 MATIC controlled two hydraulic clutches. Immediately revealed the first pluses and minuses of the device.

When there was no need for all-wheel drive, only the rear axle worked, which saved fuel.
Accordingly, the resource of the structure increased.
The couplings were made of high-strength materials, which practically did not erase them when the wheels slipped.

The plug-in drive was not as efficient as the permanent one.
Off-road abilities were, to put it mildly, not impressive.
The design turned out to be complex and very expensive; in case of a breakdown, it was necessary to fork out well.

Therefore, Mercedes engineers worked on the second generation, which in the end was very different from the first.

Second generation

Later in 1997, the second generation 4 MATIC was presented on the W210 model. This system turned out to be more durable and productive, there were a lot of differences.

This is permanent four-wheel drive, not automatically connected.
Differentials (interaxle and interwheel) were no longer equipped with mechanical locks. Here, for the first time, the 4ETS (Electronic Traction System) traction control system was installed, which practically eliminates blocking altogether.

What benefits did it provide?

The design was simplified, and therefore the repair was cheaper.
The permanent drive did its job, regardless of wheel slip, that is, it felt confident both on dry roads and off-road.
Off-road performance is much improved (again, if you do not take cars, here all 4 wheels gave confidence on the track when overtaking, turning, etc.)
Excellent work with automatic transmission.

In general, the design was a success, it was a kind of "work on the bugs", and now henceforth 4MATIC will only be "permanent drive".

Disadvantages - there are not many of them, if only we take into account that fuel consumption has increased compared to the first generation, and now the whole structure is wearing out, that is, it always constantly works. However, as Mercedes engineers assure, the resource here is really big.

third generation

Appears in 2002, immediately on a large number of C, E, and S class cars. The developers did not abandon the successful second version, but made it “smarter”, forced 4ETS to work together with a system such as ESP.

The bottom line is very simple - now the so-called free differentials are beginning to be used in the design, which work in conjunction with the electronic ESP system. Control over the road and off-road is now almost complete:

When one wheel slips, the system begins to “stop” it, transferring increased torque to other wheels that are in better gear.

The advantages of such a system are obvious - the permeability has increased by about 30 - 40%. Also increased control over the road in conditions of high speeds (drifts, sharp turns, etc.). It should be noted that 4 MATIC has received many awards.

Torque distribution

It is important to note that this drive can automatically adjust and transfer unequal torque to the wheels.

For example, passenger cars (except for the luxury S-class) have a ratio of approximately 35/65. 35% goes to the front wheels, but 65% to the rear.

SUVs (SUVs) GL, ML and R class have an equal ratio of 50% to 50%.

Luxury cars (S-classe) - adjusted to a ratio of 45% (front) and 55% (rear).

This ratio of torque is verified by many tests, as well as the structure and features of the body. It is these indicators that make cars more stable, safer and more comfortable to drive.

Now let's watch a short video.

History(I)

4matic works on the principle of distributing the torque of the motor separately to each axis of the machine. The 4matic technology was designed by Mercedes together with Steyr Daimler Pasch, a company that assembled Gelendvagens in Austria.

How Mercedes-Benz's 4Matic all-wheel drive system works

The 4Matic all-wheel drive system is used in the design of both off-road vehicles and passenger cars. In today's article we will talk about the history of the emergence of this system and its varieties.

Story

Most motorists know that all-wheel drive systems appeared a relatively long time ago, and were initially installed along with a manual transmission. However, the 4Matic transmission system, developed by Mercedes-Benz, only cooperates with automatic transmissions.

4Matic 1 was first introduced in early 1986. It was installed on a Mercedes E-class W124 car, where it worked automatically.

The principle of operation of the system is as follows: its design is based on a mechanical differential lock. The control is carried out with the help of two hydraulic clutches. The main advantage of the system is that when the ABS system is activated, 4Matic automatically turns off.

1997 was marked by the debut of the second generation all-wheel drive, which was first used on the Mercedes W210. Now all-wheel drive has become permanent. This was achieved by installing free-type differentials, which are blocked by activating the traction system.

The debut of the third modification took place in 2002. The novelty, unlike its predecessors, has become more in demand, and they began to install it in other models of the company. As for the drive system, it is, as in the previous version, constant. As for the differentials, they are also free. The regulation of the system is carried out by the system of exchange rate stability, which controls the traction force, and the moment of on / off.

The fourth modification system was first demonstrated to the public in 2006. It was tested on a Mercedes S550 car. Despite the fact that the system had the maximum similarity with its predecessor, it was regulated exclusively by the on-board computer.

At the moment, the fifth generation system is considered the most modern. The new system began to be used in even more models. For example, in 2013, 4Matic 5 was installed on the CLA 45 AMG and GL550. It should be noted that this system is fully robotic, and automatically distributes the axial load.

It is worth noting that the company's engineers have already begun work on the next version, and they promise that now it will be possible to control the PP system using buttons.

Features of the 4Matic system

At the moment, the 3rd generation is the most popular. The main reason for this lies in the relatively low cost and excellent quality of the system.

The 4Matic PP system set includes:

automatic transmission;
front and rear axle with cardan gears;
transfer case;
front and rear differential;
axle shafts of the rear wheels;
multi-speed angular joints.

If we analyze this set, we can conclude that 4Matic is a really complex mechanism, which, due to its features, cannot work with “mechanics”. The main element is the transfer case, due to which the torque is distributed. Plus, with its help, the gearbox, drive shaft and spur gears are combined.

So how does the 4Matic all-wheel drive system work? To begin with, the drive shaft is connected to a gearbox, the rear axle of which receives rotational power from a large gear, or, as some people call it, a sun gear. The front axle is connected on one side to a smaller gear, and on the other side to a cardan drive, also due to gears.

Principle of operation

Now we are talking in more detail about the Mercedes 4Matic software system. It should be noted right away that proportionally, the axial load is distributed as follows: 40% to 60%, with an advantage on the rear. Do not forget that the function of an asymmetric center differential is taken over by a planetary gearbox. On some models, you can find slightly different distribution rates: 45% to 55%.

It is worth noting that in cars that are equipped with a PP and automatic transmission system, there is no inter-axle and inter-axle differential blocker. Due to the vehicle's stability control system, traction control system, anti-lock braking system and traction control system, the on-board computer automatically adjusts the distribution of torque.

However, the developers immediately stated that cars equipped with the 4Matic all-wheel drive system consume more fuel than similar models with conventional equipment. More precisely, the level of fuel consumption increases by 0.4 liters for every 100 kilometers. At first glance, not so much, but if you look at it on a larger scale, it turns out to be a serious figure.

The differential lock is carried out by activating the ETS system. Here is the same principle of operation as in the electronic blocker. The system automatically triggers the required moment, and the slipping wheel is braked, and instead of it, the wheel is additionally loaded, which has normal grip with the road surface.

Due to these innovations, a car with a PP system boasts a good starting speed, stable movement on poor-quality road surfaces and excellent handling.

Conclusion

The 4Matic all-wheel drive system is one of the most popular. At the moment, the developers have already released as many as five versions that do not feel serious competition.

Initially, the system was developed for a limited number of models, but over time their number has grown.

The 3rd generation system is in the greatest demand. This is primarily due to the fact that it was at the beginning of the 2000s that a sharp rise in the German concern Mercedes began. In order to meet the needs of the market, the company has dramatically increased productivity and reduced the cost of cars.

As a result, we can say that the system is not particularly complex, but nevertheless it is very good and performs well on SUVs, for example, such as the Mercedes-Benz GL or Mercedes-Benz M.

What does 4Matic stand for?

This is just a marketing designation for an all-wheel drive system developed by engineers from Mercedes-Benz and Steyr-Daimler-Puch in 1986. It appeared as a result of abbreviations, where "4" is all the drive wheels, and "matic" is from automatic transmission. A feature of this transmission, among other things, was that almost all models of the German brand were equipped with it in tandem with an automatic transmission. The first car on which such a four-wheel drive was installed was the W124 model (the modern E-Class). It was characterized by the fact that it was connected automatically and had mechanical locks for the center and rear axle differentials. The system electronics controlled the first generation 4Matic with two hydraulic clutches. The second generation of this system, first presented on the W210 model in 1997, differed significantly from the previous generation both in efficiency and in principle of operation. Firstly, it was a permanent four-wheel drive, and not automatically connected, as in the first generation, and secondly, the differentials (interaxle and interwheel) did not have mechanical locks, but nevertheless, a similar effect was achieved due to the traction control system. efforts. Finally, the third and last generation of 4Matic debuted in 2002 on three models at once: C-Class, E-Class and S-Class. It, in turn, differed from the second generation, but not so radically: it was the same permanent four-wheel drive with free-type differentials. But control over the movement of the car and its stability on the track is achieved using the ESP system, which also includes a traction control system. The latter performs a function similar to an electronic differential lock, slowing down, when necessary, stalled wheels and transferring increased torque to wheels with better grip on the roadway.

Mercedes 4. What does 4 matic mean. On Mercedes cars? Let's analyze the pros and cons

Mercedes-AMG GT 4-Door Coupe 2018-2019 photo video, price of a complete set of Mercedes AMG GT coupe

Sports car Mercedes-AMG GT 4-Door Coupe (Mercedes-AMG GT 4) is presented publicly as part of the Geneva International Motor Show 2018. From now on, the German company's model line includes three models of Mercedes-AMG GT (Mercedes-AMG GT) - a two-seater sports car with a closed body Mercedes-AMG GT coupe, a convertible with a soft folding roof Mercedes-AMG GT Roadster and a 5-door hatchback, which received the official name of Mercedes -AMG GT 4-Door Coupe. In our review, the new 2018-2019 Mercedes-AMG GT 4-Door Coupe - photos and videos, price and equipment, technical specifications of a sports 5-door hatchback, declared by the manufacturer as a 4-door coupe. Sales of the 5-door Mercedes-AMG GT will start in the summer of 2018 at a price of 120-125 thousand euros for a 435-horsepower all-wheel drive Mercedes-AMG GT 53 4Matic+.

photo Mercedes-AMG GT 4-Door Coupe 2018-2019

If the two-door Mercedes-AMG GT and Mercedes-AMG GT Roadster are called into the ranks of Mercedes to compete with the Porsche 911 coupe and Porsche 911 Cabriolet, then the Mercedes-AMG GT 4-Door Coupe will try to knock down the Porsche Panamera. And take my word for it, the new Mercedes will make it easy.

It should be noted right away that a large 5-door hatchback with a comfortable 4-5-seater saloon and a luggage compartment capable of receiving 395-1324 liters, depending on the position of the rear seat backs, is not a platform brother of the AMG GT coupe and roadster models (the original platform with two lever suspension of the front and rear wheels, as well as the “robot” Getrag located at the rear axle (transaxle scheme)). At the heart of the Mercedes-AMG GT 4 is a modular MRA bogie with two-link front and multi-link rear suspension, as well as an automatic transmission located just behind the engine at the front of the car. So the brothers of the novelty are the new generations of Mercedes-Benz CLS and Mercedes-Benz E-Class.

The question immediately arises, why does Mercedes-Benz need two Mercedes-Benz CLS and Mercedes-AMG GT 4-Door Coupe cars in the niche of sports “four-door coupes”?

First, cars with different body types: CLS - 4-door sedan stylized as a coupe, and GT 4 - 5-door hatchback also stylized as a coupe.
Secondly, the 5-door GT looks more aggressive and brutal than the sedan's platform brother.
Thirdly, the Mercedes-AMG GT 4-Door Coupe will not have modest versions with diesel engines, rear-wheel drive and a price tag in the region of 70,000 euros, but only the most powerful gasoline engines, all-wheel drive and a price starting from at least 120-125 thousand euros.

As confirmation, we suggest that you get acquainted with the technical characteristics of the new 2018-2019 Mercedes-AMG GT 4-Door Coupe, offered from the start of sales in three versions with powerful petrol turbo engines.

Mercedes-AMG GT 53 4Matic + with a 3.0-liter six-cylinder engine (435 hp 520 Nm), supplemented by an EQ Boost system starter-alternator (22 hp 250 Nm), which helps the car during intensive acceleration. The gearbox is automatic 9-speed (AMG Speedshift TCT 9G), 4Matic + all-wheel drive transmission (by default, the drive wheels are rear, and if necessary, the multi-plate clutch connects the front wheels, thus providing the car with all-wheel drive). Such a technical arsenal provides a 5-door curb weight of 1970 kg with acceleration dynamics from 0 to 100 km / h in 4.5 seconds and a maximum speed of 285 km, declared fuel consumption of 9.1-9.4 liters. Spring suspension, disc brakes on all wheels.

Mercedes-AMG GT 63 4Matic + with 4.0-liter V8 Biturbo (585 hp 800 hp), equipped with new two-line turbochargers, liquid intercooler and half-cylinder deactivation system. AMG Speedshift MCT 9G gearbox with a wet clutch disc instead of a traditional torque converter, of course, the proprietary 4Matic + all-wheel drive system, as well as air suspension and rear steering wheels in corners with a pair of electric actuators (at speeds up to 100 mph they turn in the opposite direction of the front wheels , and at a higher speed turning in the same direction as the front ones). A car with a curb weight of 2025 kg shoots up to 100 km / h in 3.4 seconds, a maximum speed of 310 km / h, an average fuel consumption of 11.0-11.2 liters.

Mercedes-AMG GT 63 S 4Matic + with a 4.0-liter V8 Biturbo petrol (639 hp 800 Nm), AMG Speedshift MCT 9G “automatic”, 4Matic + all-wheel drive system, supplemented by an electronically controlled rear differential. The transmission additionally received a drift mode with full ESP shutdown and a front-mounted multi-plate clutch. In drift mode, the 5-door sports car is exclusively rear-wheel drive. Suspension, of course, pneumatic with thrusters rear wheels. The most powerful engine accelerates a car with a curb weight of 2045 kg to the first "hundred" in 3.2 seconds, a top speed of 315 mph, and an average fuel consumption of at least 11.2 liters.

As standard equipment for all modifications of the 5-door Mercedes-AMG GT, the AMG Track Pace system is offered, which helps to choose the optimal mode for driving on the race track (Slippery, Comfort, Sport, Sport +, Race and Individual), supplemented by a safety system with several prescribed levels driving skills (Basic, Advanced, Pro and Master). The higher the level, the less the electronics interfere with driving, tracking and reading as many as 80 parameters.

photo salon Mercedes-AMG GT 4-Door Coupe 2018-2019

I would like to note that the new 5-door Mercedes sports car has surpassed all modifications of the Porsche Panamera in terms of dynamic and speed characteristics. For example, the 550-horsepower Porsche Panamera Turbo picks up the first “hundred” in 3.6-3.8 seconds and accelerates to a maximum of 306 km / h, and the hybrid and most powerful Panamera Turbo S E-Hybrid in the line with a 680-horsepower power plant is able to accelerate from 0 to 100 mph in 3.4 seconds and reach a top speed of 310 mph, but… that's only enough to compete with the Mercedes-AMG GT 63 4Matic+, but not the Mercedes-AMG GT 63 S 4Matic+. It's hard to imagine what a full-fledged Mercedes-AMG GT 4 hybrid with an 800-horsepower power plant will be capable of.

We figured out the technique, and let's return to the exterior and interior of the chic 5-door hatchback, positioned by Daimler as a 4-door coupe. The exterior design of the body, as mentioned above in our review, is aggressively brutal, stylish, bright and charismatic, as befits an expensive sports car. In the presence of LED matrix headlights, a powerful body complemented by a mass of aerodynamic chips - splitters, spoilers, active blinds (adjustable rear spoiler, and for a fee even made of carbon fiber), huge wheels - 255/45 R19 on the front axle and 285/40 R19 on the rear axle for the Mercedes-AMG GT 53 4Matic+ and Mercedes-AMG GT 63 4Matic+ versions and the larger 265/40 R20 and 295/35 R20 for the powerful Mercedes-AMG GT 63 S 4Matic+ modification. If desired, 21-inch forged aluminum wheels with 275/35 R21 tires at the front and 315/30 R21 at the rear can be installed on any version of the 5-door for an extra charge.

The interior of the Mercedes-AMG GT hatchback, at the request of the customer, can be either a 5-seater with a rear sofa designed for three, or a 4-seater with two separate seats for rear passengers. At the same time, all the seats in the cabin are sports with powerful lateral support and anatomical backrest profile. The driver and front passenger seats are like a GT3 racing car. The design of the front of the Mercedes-AMG GT 4-Door Coupe is a combination of the front panel from the platform Mercedes-Benz CLS and the tunnel of the two-door Mercedes-AMG GT.

Available analog (for Mercedes-AMG GT 53) or digital instrument panel (Mercedes-AMG GT 63 and Mercedes-AMG GT 63 S versions) with a screen diagonal of 12.3 inches, an advanced multimedia system with a similar display size to the dashboard, sports steering wheel with touchpads, background LED interior lighting (64 colors to choose from), driver and front passenger seats with electric adjustment, ventilation and heating, heated and ventilated rear seats, three or four zone climate control and a lot of electronic security systems, assistants and assistants from the automatic braking system and adaptive cruise control, which works with the help of radars, to the Drive Pilot complex, which is capable of independently driving a car on the highway.

The 4 matic all-wheel drive system was completely developed by the specialists of the Mercedes-Benz automobile concern.

4matic what does it mean?

The car is equipped with a 4 matic transmission, which means that if the rear drive wheels are stuck, then the torque is redistributed to the wheels of the front axle. Such operation of the 4matic all-wheel drive system occurs due to the change in the degree of interaction of the clutch discs through the hydraulic drive of the central electronic system of the car. After that, there is a gradual redistribution of torque to the axle, which has better contact between the wheels and the road surface. As practice has shown, the 4matic all-wheel drive system has significant advantages over other rear- or front-wheel drive systems. However, it has a rather complex structure and high cost.

So why am I?

A lot of people are having a hard time in business these days. This is of course 99% tied to an emotional background, but still. Ups, downs, competition, sanctions, exchange rates, etc. the list is endless.

And what about 4matic?

As you have already noticed, my website is called, and I want everything in you and in my life to be like in the all-wheel drive system of this car! After all, a business is much more than just “selling seeds in the market”, you have to control many work processes. Some things work better, some things worse, some things don't work at all. At the initial stages of development, this is normal, many even live like this all their lives. But when you start to scale, you simply cannot keep track of everything, and you need to overcome this bar! Then you will be able to drive like a tank over any terrain, knowing that you have a strong team and everything works like an “all-wheel drive system”, you don’t need to look back, because you eat very fast forward.

First introduced on the E-Class W124 in 1986 (1987?) and was available on models with 2.6 and 3.0 liter 6-cylinder petrol and diesel engines.

The 4WD connection was made electronically automatically by the signals of the ABS sensors and was implemented by hydraulic multi-plate clutches (locking the center clutch and rear axle differential, the front differential was open). When the ABS system is activated, both clutches open.

It has the following modes of operation:

2WD, in which the rear axle was leading, and the front axle was turned off;
4WD with 35/65 torque distribution due to the variable degree of clutch closure (according to other sources, a differential was still installed there);
4WD with a locked center clutch and a 50/50 torque ratio (if necessary, the ASD system also locked the rear differential).

Plus: some fuel economy in 2WD mode.

Cons: low efficiency 4WD on-demand, complex and expensive design.

Second generation 4Matic (W210 and W163, permanent 4WD)

To uncover...

Implemented on the Mercedes-Benz W210 E-class car since 1997 as an option (only for the left-hand drive version). The standard was present on the M-class models (W163), launched for sale since 1997, and on the R-class. Installed only on left-hand drive versions.

It is a permanent 4WD with three open differentials and imitation of their blocking using a traction control system (4ETS technology, 4-wheel Electronic Traction System). 35/65 forward/reverse power distribution via planetary gear.

Pros: simplicity of design, excellent adequacy and better 4WD cross-country ability.

Minus: slightly more fuel consumption relative to 2WD for transmission losses (at least 0.4 l / 100km).

Third generation 4Matic (W203, W211 and W220, permanent 4WD)

To uncover...

It appeared in 2002 on C- (W203), E- (W211) and S-classes (W220) cars. It represents the development of the second generation by adding electronic systems, which made it possible to increase the cross-country ability and the adequacy / stability of cars.

4WD - permanent, all differentials are open. Imitation of locks and general stability of the car is provided by a set of systems (ESP stabilization, 4ETS traction control, ASR traction control, DSR descent control system and of course ABS).

Axle traction distribution:

for cars (except W221) and crossovers - 40/60 (according to other sources - 35/65) front / rear;
for GL, ML and R-classes - 50/50 (symmetrical);
for S- and V-classes - 45/55;
for Mercedes-AMG (AMG Performance 4Matic system) such as E63 AMG, CLS63 AMG (Shooting Brake), S63 AMG (Coupe) - 33/67.

The third generation 4Matic all-wheel drive consists of:

automatic transmission;
transfer box;
cardan transmission to the front axle;
cardan transmission to the rear axle;
main gear and rear cross-axle differential;
main gear and front cross-axle differential;
rear wheel axles.

The central structural element of the 4Matic system is the transfer case, which continuously distributes torque along the vehicle's axles. The razdatka combines a double planetary gearbox (performs the function of an asymmetric center differential in the box), spur gears, and drive shafts. The drive shaft is connected to the planetary gear carrier. The rear axle drive shaft is driven by a larger diameter sun gear. The front axle drive shaft is hollow, connected to a small-diameter sun gear, on the other hand, with the help of cylindrical gears, it is connected to the cardan drive of the front axle.

1 - automatic transmission, 2 - transfer case, 3 - cardan drive of the front axle drive, 4 - final drive and front cross-axle differential, 5 - drive shafts with constant velocity joints, 6 - cardan drive of the rear axle drive

1 - drive shaft, 2 - rear axle drive shaft, 3 - planetary gear, 4 - spur gears, 5 - front axle drive shaft

Fourth Generation 4Matic (Permanent 4WD)

To uncover...

It was introduced on the 2006 S550 4Matic and later on the W204.

It is a further development of the 2nd and 3rd generations based on more advanced electronics. It uses a cylindrical differential, "blocked" by an uncontrolled double-disk clutch, which distributes the input torque between the axles in a 45/55 ratio in favor of the rear wheels. When accelerating on a uniform slippery surface, the clutch blocks the center differential, adding stability to the car. In the event that the torque difference between the front and rear axles exceeds 50 Nm, the clutch slips - for example, in turns. Traction control is provided by the 4ETS system with the help of service brakes. The ESP, ASR and 4ETS systems in the new system are calibrated to operate as late as possible, allowing maximum engine power to be realized.

Fifth generation 4Matic (4WD on-demand)

To uncover...

Introduced in 2013 on CLA 45 AMG and Mercedes-Benz GL 500 cars, it is an on-demand 4WD (that is, not permanent, but plug-in) on a front-wheel drive architecture with a transversely front-mounted engine.

The front and rear differentials are open, there is no center differential. The set of electronic systems is the same, imitation of blocking is also provided by 4ETS. Power take-off to the rear axle is handled by a PTU (power take-off unit) integrated into the 7G-DCT dual-clutch robotic gearbox. The PTU turned out to be very compact, and it has a common lubrication system with the box, due to which 25% of the weight was saved.

Under normal conditions, the torque is distributed between the front and rear axles in proportions from 100/0 to 50/50. So, when accelerating a car with a full load at a speed of 50 km / h, the ratio changes to 60/40, with fast cornering it becomes 50/50, with loss of traction of the front wheels - 10/90, in the case of hard braking with ABS - 100 /0. The redistribution of the moment is achieved due to the variable degree of compression of the center clutch.
