The UAZ-452 model, known to the common people as the "Loaf", is a native of the Ulyanovsk Automobile Plant with a long history. The start of production dates back to 1965. This is a vehicle in which you can carry goods and passengers. It has a 4x4 wheelbase that allows you to overcome harsh off-road areas.

UAZ "Loaf" has a wide range of modifications: cargo van, passenger-and-freight model, bus, special vehicles.

The van is designed quite simply, but, despite this, it is reliable and has good cross-country ability. And thanks to its price and versatility, "Loaf" should appeal to lovers of tuning and connoisseurs of "off-road" classics.

Specifications UAZ "Loaf" Engine

The car is equipped gasoline engine corresponding to Euro-4 class. Its volume is 2.693 liters, power - 112 liters. s., torque - 198 N m at 2500 rpm. Max Speed van equals 127 km/h. The engine is paired with a 5-speed mechanical box gears.

Dimensions

Depending on the modification, the dimensions of the UAZ "Loaf" have some differences.

Cargo van:

UAZ "Loaf" Bus:

UAZ "Loaf" Combi:

cargo space

The van can take on board cargo weighing from 400 kg to 1 ton. Dimensions luggage compartment vary depending on the type of vehicle. Any modification is ready to cope with various tasks, whether it is the transportation of passengers or any materials. Swing rear doors and low loading height facilitate the process of loading and unloading.

Safety

One of the main drawbacks of the UAZ Loaf model is the complete absence of any security systems. There are also no airbags. The only thing the van is equipped with is seat belts for the driver and passengers.

Salon

For drivers, comfortable seats were designed with the ability to adjust longitudinally and even heated. The central panel is equipped with buttons for turning on the heating and "emergency gang"; there is also a niche for an audio system; 12V socket and "glove box".

For those sitting in the rear of the cabin, there is another heater with a fan, thanks to which an even, optimal temperature is maintained in the car.

By the way, onboard models UAZ have an updated steering wheel with different switches.

Verdict

Do not forget that this car was not originally created for comfortable ride citizens, but for military purposes. And that is why the “loaf” does not take over the cross-country ability of any other SUV in areas that are absolutely unsuitable for driving.

Buyers planning to purchase a UAZ car pay attention not only to its specifications and features of operation, but also on overall dimensions. Since the products of the Ulyanovsk Automobile Plant are used for cross-country travel, as well as for the transport of passengers and various cargoes, the dimensions of these vehicles cannot be small.

Dimensions of the classic model

On average, UAZ weighs about 3 tons. Each car model has its own design features, which determine the dimensions of the product. In addition, the size of the machine is affected by its modification and tuning.

Parameters of the popular model 3741

The dimensions of the popular utility vehicle based on the 3741, popularly referred to as the "loaf", are 4390 mm long, 2085 mm high and 1940 mm wide. The mass of this product reaches 2720 kg. IN cargo hold Such a machine can carry cargo weighing up to one ton.

On its platform, it is allowed to place transported objects weighing no more than 700 kg. The number of seats in a UAZ car of this type can vary from two to ten.

In the cabin of the sanitary version of the car (UAZ 452A, UAZ 452G), one medical worker can be accommodated, as well as up to 4 stretchers or 6 patients on benches.

Model 3151 Variations

Loaf Options

Cars with model number 3151 come in a wide variety of sizes. This is due to the fact that when developing jeeps, serious attention is paid to the convenience of transportation. Accordingly, each modification is maximally adapted to the needs for which it was designed. For example, the dimensions of the short-wheelbase "Naughty" are as follows: 3720 mm in length, 1850 mm in height and 1965 in width. Wheelbase this model reaches only 2 meters. Up to 4 people, including the driver, can be placed in the “baby” cabin.

The overall dimensions of a standard UAZ 3151 are 4025 x 1785 x 2045 mm. The capacity of this modification is 7 people. largest sizes in this series, the long- and wide-base "Bars" 3159 is distinguished. Its parameters reach 4550 x 1962 x 2100 mm. The wheelbase of the SUV exceeds 2760 mm, and ground clearance is 700 mm.

Model 3151 has a large number of tuned versions produced in small batches. Many of these machines were modified to affect their dimensions. In particular, a convenient and practical removable roof was installed in UAZ 31512-LLD.

Ulyanovsk car factory produces many worthy models that have been popular with consumers for many years. Such is the UAZ-452, which is often called the "Loaf". It began to be produced in the last century, but is still able to compete with many modern vehicles.

Loaf car design

The UAZ Loaf car was created taking into account the fact that it will be possible to transport heavy loads with a total weight of up to 800 kg. Therefore, the chassis from the GAZ-69 was chosen as the basis of the vehicle. But in the process of designing and assembling the car, it turned out that it was too short and could not withstand such loads.

Therefore, the developers decided to slightly re-equip the body, as a result of which two modifications of the UAZ-452 were created. One of them was a body or wagon, and the second was an onboard one.

The designers decided to strengthen the car frame with transverse stiffeners. They were located in the upper part, which led to the appearance of the name "Loaf". This design was approved in the 50s of the last century, after which it began mass production car.

The number of seats and their location in the cabin varies, depending on the modification of the vehicle and its purpose. To get inside, there are stationary steps and side doors with a handle. The rear opening has double-leaf hinged doors, a folding footboard.

UAZ car modifications

UAZ Loaf after creation was modified all the time, which led to the creation of new models with some features. The most popular of them:

452A. The well-known ambulance, which can accommodate up to 6 people or four stretchers;
452AC. Known modification ambulance 452A;
452AE. It is a chassis suitable for mounting various auxiliary equipment;
452V. It is a minibus capable of carrying up to 10 people;

452D. Primarily used as a television machine;
452G. Played the role medical vehicle, differed in large volume;
452K. The bus is designed to carry 16 people. Not released into mass production due to complex design;
452P. It is a truck tractor.

The well-known Loaf has many advantages, but there are also some disadvantages.

Advantages of the Loaf car

The main advantage of UAZ Loaf is easy repair and affordable spare parts. This advantage compensates for the lack of comfort in the cabin. The car is also different cross-country ability, versatility and capacity. In the Loaf's cabin, in addition to the driver, there can be nine more people and one ton of cargo. The car is able to transfer this weight to long distance without losing their qualities and without significant damage to the main working units.

UAZ-452 can be carried out with a compartment driver's seat barrier or without it. If desired, its interior can be equipped with a table, a heater high power, which will allow you to use the Loaf for trips to nature or for travel.

Optimal technical and operating parameters UAZ-452 is another advantage of it. It is equipped with a powerful and economical engine. Fuel consumption is 17 liters per 100 km with a volume fuel tank 50 l. The motor is very reliable, which is appreciated when transporting goods or people over long distances. If it stalls, the main cause of failure is most often damaged spark plugs.

The design of the car is quite simple. Therefore, it is often used by specialized services ( health care, army) to organize their work. Even if the "Loaf" stalls, most breakdowns can be quickly and effortlessly eliminated in the most extreme conditions.

Disadvantages of the UAZ car

The main drawback of the UAZ-452 is poor-quality external metal plating. It is subject to corrosion, therefore it constantly requires repair and replacement over time. After several years of active operation, the skin is covered through holes, and after ten years - completely destroyed. It is not difficult to replace it, since the Loaf has a frame structure.

After the launch of the UAZ-452, the engineers did nothing to improve driving safety. The car does not have airbags, which in the event of an accident leads to serious injuries to the driver and crew. But usually such shortcomings seem like trifles in comparison with the numerous advantages of the vehicle, which have been tested for decades of operation.

UAZ Loaf: technical characteristics and performance characteristics vary depending on the selected modification (409, 452, 452 A, 452 D). This vehicle is manufactured Ulyanovsk plant since 1965

For Maintenance to the bridge rear type it is necessary to fill in 1-1.5 liters of oil, raise the entire mechanism with a jack and start the power unit so that the oil liquid heats up. Parts are recommended to be washed with kerosene.

The UAZ-452 front axle onboard includes a crankcase, which is equipped with protective covers and semi-axial devices. On the covers are safety valves that regulate the level of pressure oily liquid in system. Along the edges of the casing there are pivot assemblies with ball bearings. Design feature of this bridge is to connect the hub of the wheel mechanism with the axle shaft. To do this, a clutch is installed here, which ensures the transmission of torque from the differentials to the wheels.

Also, the design of this bridge includes main gear and a differential, which consists of a pinion gear and satellites.

During the execution of work, the front drive axle has a load of 675 kg, and the rear axle - 400 kg.

Transfer case and gearbox

The UAZ-452D dispenser consists of drive shafts drive axles and intermediate shafts. This also includes gears located in the crankcase, the body of which is made of cast iron. All these parts are connected to the crankcase cover.

You need to use the distributor like this:

In order to turn on the gearbox of the transport, a clutch is used, which activates the operation of the blocking rings and gears. The same mechanism is used to shift gears.

electrical equipment

difference electrical circuit injector from electrical circuit carbureted UAZ lies in the fact that the latter has more than new model optical switch.

Electrical equipment consists of such systems as:

power supply;
light signaling;
outdoor and indoor lighting;
instrumentation;
heating;
power windows and wipers;
sound alarm;
ignition system consisting of an electric starter to start power unit.

The power supply system is necessary to power consumers electric current with the engine running. Two power sources are used here. rechargeable batteries with a capacity of 100 Ah. Their negative terminal is connected to the mass of the vehicle through a special switch with remote control from the driver's cab.

The electrical equipment generator connection diagram is equipped with a relay that breaks the excitation winding circuit of the generator set when the electric torch device is activated.

Light signaling is necessary to notify other drivers of an impending turn or braking. This includes: emergency signals, stop signals, center differential, pilot lamps differential locks, light indicators of the parking brake system.

The heating system is necessary for comfortable work V winter period. Electric motors escalate air flow, which passes through the radiator, thereby providing optimal temperature regime in the driver's cab.

Fuel system

The fuel system of this UAZ model consists of:

throttle type assembly;
check valve;
adsorber;
diagnostic fitting;
fuel rail;
fasteners;
injection systems fuel fluid;
a screw that regulates the pressure level of the fuel fluid in the system;
pump element;
separator;
fuel drive;
fuel filter element;
gravity valve;
nozzles;
containers with a ventilation system;
fuel tank and oil tank.

Technical characteristics and indicators of the system:

working volume of the UAZ Loaf engine - 2.45 l;
the average fuel consumption of UAZ Bukhanka is 13 liters per 100 kilometers.

Refueling volumes of the vehicle:

the volume of the fuel tank UAZ Loaf - 77 l;
capacity for oily liquid - 22 l;
hydraulic system - 13 l.

When the ignition key is turned, the operation of the fuel tank is activated. Gasoline from the fuel tank passes into the pumping mechanism, and from there into the supply line, which leads to the filter element. At this stage, the fuel passes the stage of purification from small impurities. After that, it flows into the regulator. To maintain the optimum pressure level, excess fluid is returned to the gas tank.

After the regulator, gasoline is supplied to fuel rail, which distributes it to the nozzles. going on direct injection fuel into the passing compressed air stream.

For stable and reliable operation all transport systems, it is recommended to use gasoline with octane rating AI-92 or AI-95.

Brake system

It has rear and front drum brakes.

The drum brake system of the UAZ Loaf consists of a parking, working and auxiliary mechanism.

The working system includes the main brake cylinder, vacuum booster, rear pressure regulator brake mechanisms, pads, ABS block, steering column, working contours.

The main cylindrical mechanism converts the force that comes from the brake pedal into the pressure of the working fluid and distributes it along the contours, as a result of which the vehicle is braked. An amplifier is needed to create more pressure in the system.

The pistons of the working cylinders begin to move brake pads to the wheel drums. With further pressure on the brake pedal, the rotation of the wheel mechanisms slows down, and the pressure of the working fluid increases to 15 MPa.

When the driver releases the pedal, the return spring puts the main cylinder mechanism in the neutral position, the fluid flows into the cylinder, and the shoes release the drums, which leads to a decrease in the pressure level.

The parking system is necessary to keep the car in one place for a long time, for emergency braking and to prevent spontaneous movement of the vehicle on a slope.

Engine cooling system

Transport equipped fluid system engine cooling. The design of this mechanism includes:

radiator outlet hose;
protective casing of the radiator;
water shirts;
water type pump;
cork;
fastening mechanisms;
radiator inlet hose;
thermostat housing;
fan;
cylinder block;
drain tap;
fitting required to release the air flow;
inlet hose and clutch device;
expansion tank.

This system is responsible for lubricating engine elements, cooling exhaust gases, heating air in ventilation, in the heating and air conditioning mechanism, as well as for circulating coolant in the turbocharging system.

Three-row radiators made of copper are installed here, and forced fan, which is located on the pulley. Fan operation does not stop as long as the crankshaft is spinning.

To circulate the liquid in the system, a water pump is installed here, which ensures uninterrupted movement of the liquid to the radiator part and back.

The thermostat is used as a switch between the small and large circle of circulation. It opens when the liquid is heated to +80°C.

Fluid moves through pipes from one element to another. Each time before starting the operation of the UAZ, it is recommended to inspect this device for damage and defects. In order to prevent the occurrence of corrosion, it is necessary to change the water jackets every 6 months.

Heating system

On this vehicle water heater installed.

The heating and heating system of the driver's cab consists of the following elements:

mounting block;
electric motor switch;
resistor;
nozzles;
flaps;
fan;
ignition switch.

The radiator is located behind the front panel of the heating device. Two tubes are connected to it, through which the liquid enters the radiator system. This working fluid circulates with a special pump element.

When the oil in the engine reaches the required temperature, the heat exchange process begins. Antifreeze reduces the temperature level of the power unit, taking away some of the heat from it. Hot antifreeze flows into the radiator of the stove, due to which the radiator part heats up. At the same time, the fan begins to drive cold air through heating system. The warm air flow enters the passenger compartment and the driver's cab, and the cooled working fluid enters the motor housing again and cools it.

At the outlet of the oven, the temperature must be at least +30°C. This will help warm up the interior of the car and prevent the windows from fogging up. The switch located on dashboard, will help to adjust the position of the flaps and the direction of warm air.

The stove can only be turned on when the liquid is heated to + 50 ° C, otherwise rust may appear.
