Mechanical brake interlock Technoblock ( Tecnoblock, Italia) is designed to protect against theft of various categories Vehicle: passenger cars of domestic and foreign production, including off-road vehicles, all types of trucks, road-building machines, wheeled and caterpillar special equipment, trailers and semi-trailers of truck tractors.

The peculiarity of the Tecnoblock blocker is that they are not used to protect the vehicle from theft electronic devices, and there is no binding to the mechanical components of the car. The principle of operation of the Technoblock blocker is based on blocking the operation of pneumatic and hydraulic systems s and starter blocking.

The secrecy of the brake blocker is ensured by the covert installation of the Technoblock brake blocker in the car. The security mode is activated using a locking mechanism, the locking cylinder of which is located in the car.

Hydraulic and pneumatic systems vehicles are locked thanks to a professionally built-in mechanical non-return valve, which is controlled by turning the key in the lock cylinder of the locking mechanism. The hydraulic and pneumatic systems of the car are blocked thanks to a mechanical check valve professionally built into them, which is controlled by turning the key in the lock cylinder of the locking mechanism.

In the event of an attempted theft, the Tecnoblock brake interlock is activated when the clutch or brake pedal is pressed, excluding the very possibility of independent movement of the vehicle. Thus, the blocker Technoblock provides reliable protection vehicle, since it is impossible to steal a vehicle with a broken clutch and locked wheels.

To disarm the vehicle, just turn the key to reverse side. Arming the Technoblock brake interlock in the armed mode is carried out only when the car is stopped. When the vehicle is moving, the security mode is turned off and does not affect the operation of the standard equipment of the car.

The high reliability of the Technoblock brake interlock is ensured by strengthening the body of the locking device, protecting it from drilling and turning the lock cylinder with the help of power equipment. The lock provides an increased safe level of secrecy due to the possibility of using various combinations. The set includes three keys with complex laser perforation on 4 sides in the form of recesses of an unusual oval shape, which provides reliable protection against forgery. The metal part of each key is engraved with its twelve-digit personal identification number.

An attempt to break the locking mechanism leads to depressurization of the pneumatic and hydraulic systems of the car, in which its further operation becomes impossible.

Since the dismantling of the Technoblock brake interlock and the subsequent restoration of the car’s performance require a lot of effort and serious time costs, theft of a car equipped with this guard is not of interest to intruders.

Tecnoblock provides a high degree car protection in the following situations:

when trying to traditional theft from a parking place;
when stolen with the help of stolen car keys;
when the car is left with the engine running to warm up in winter;
in case of elementary forgetfulness when arming the vehicle;
when trying to dismantle the system;
when using special radio-electronic means.

Depending on the selected configuration of Technoblock brake-blocking devices, the system provides simple (standard) protection of the vehicle or active (mandatory) protection.

The blocker provides visual control of the mode: the activation of the "Security" mode is signaled by a flashing red LED (a blue LED can be connected separately).

Operating temperature range: from -40 to +85 degrees Celsius. (Tecnoblock) on a car takes from 4 to 6 hours, and for equipping truck it will take 6 to 12 hours.

The high-tech Tecnoblock mechanical brake interlock complies with the new EU Safety Directives that apply to vehicles operating in the territory European countries. Besides, this equipment recommended for use by reliable domestic and foreign insurance and leasing companies.

For luxury and business class cars, expensive buses, special and construction equipment the discount to the base rate for insurance covers the costs of installing the Technoblock during the year of car operation. For other types of vehicles, savings on insurance for 2-3 years fully pays off the costs incurred for equipping security system Technoblock.

The installation and operation of the Tecnoblock brake interlock is permitted by GOSSTANDARD of Russia and approved by the certification center of the Ministry of Internal Affairs of the Russian Federation.

Factory warranty for new car when installing the system, the Technoblock is saved.

Warranty maintenance of the Technoblock brake interlock lasts 36 months from the date of installation (sale) of the system.

Brake devices of mine drum hoisting machines with drum diameter up to 3.5 m

Hoisting machines with a drum diameter of up to 3.5 m are equipped with braking devices with spring-hydraulic, spring-pneumatic and pneumatic spring-load brake drive.

Brake devices with spring-hydraulic brake drive have two executive bodies, two spring-hydraulic drives, a control and blocking station. The executive bodies work synchronously and are used both during service and safety braking. Each shoe-type brake actuator acts on the brake rim of the drum, creating half the required braking torque.

The executive body of the brake consists of brake pads 8, pivotally connected to the brake beams 6. The latter are mounted on supports 10, fixed on the frame of the machine with bolts and stops. On the brake pads are fixed press-mass friction linings 7. The movement of the brake beams is limited by the stop 9. The angular lever 3 is pivotally connected to the right brake beam 6, and the horizontal rod 2 and the hinged head 1 are connected to the left brake beam. The brake drive rod 4 is connected to the angular lever 3. When the rod 4 moves down (up), the brake pads 8 approach (retract) 8. The gap between the rim and the brake pads is uniformly distributed by a spring link 5. The swivel joints of the executive body are made on plain bearings, lubrication which is carried out through axial and radial drilling in the connecting rollers.

In the most common radial-type brake actuators, press shoes act on single-drum steel or cast-iron rims connected to the rope winder. The hoist has two brake rims, each with a pair of shoes. The pads must have the property of non-abrasiveness, high strength, wear resistance, which is maintained at temperatures up to 200-250 0 s. for a long time, without loss of braking qualities, insensitivity to oil and water.

To loosen the rope tension at the place of its attachment to the drum, on the surface of the drum there must be at least 3 turns of friction when lining with wood and press mass and at least 5 turns of friction on drums not lined with friction materials. In addition to the friction coils, there should be spare coils for periodic testing of the rope.

If there is more than one layer of winding on the drum, the drum flange should protrude above the top layer by 2.5 rope diameters.

When inspecting the brake rim, you must:

the condition of the rim and the reliability of its connection with the drum. In case of significant wear of the brake rim, the latter must be reinforced with special linings or replaced with a new one, the minimum allowable thickness of the brake rim is agreed with the manufacturer. Working surface The brake rim must be flat and smooth. If there are scallops, scratches, gouges or dents, the rim should be turned or sanded. Minor Defects remove by scraping and polishing. The size of the ledges at the joints of the brake rims should not exceed 0.1 mm. For large displacements, the protruding edge of the joint should be machined flush or the protrusion with a radius of at least 100 m should be rolled up. Oil or water must not get on the working surface of the brake rims;
The value of the runout of the brake rim with an indicator mounted on a rigid base in two or three sections along the width of the rim. The indicator can be mounted on parts of the brake actuator, if available. full confidence in the immobility of these parts during the measurement. The speed of the brake rim during the measurement should be 0.2-0.3 m/s. In this case, it is desirable that the brake does not participate in the work, and the required speed is provided by the electric drive system of the machine, since the operation of the brake can introduce a measurement error, even if the indicator is not fixed to the brake actuator. For machines in operation, the allowable runout value can be taken larger and be up to 0.8 mm for machines with a drum diameter of up to 3.5 m.
heating temperature. Excessive heat can be caused by poor fit of the brake pads, improper adjustment of the brake actuator, incomplete braking of the machine due to incorrect adjustment of the brake actuator, and bulging of the rim (due to local heating). The appearance of tarnishing colors on the rim and burning of the pads is unacceptable.

From technical condition The reliability of the brake, the durability of the brake pads largely depend on the brake rim. The working surface of the brake rim must be clean and smooth. As a result of operation, roughness scratches, cracks at the junction of the two halves of the rim may appear on the brake rim.

In the presence of scratches and roughness, the rim is polished. If cracks are found in the welded joints of the halves of the brake rim weld the cracks are removed in place and welded again.

When ellipse appears, the brake rim is machined and then polished. Elipse rim or local bulges adversely affect the operation of the brake system. When the convex part of the rim passes under the brake shoe, when the machine is slowed down, the braking torque increases, then after this part leaves the brake shoe, the braking torque decreases.

In addition, the ellipse of the rim causes increased gaps between the brake pads and the rim, which increases the duration idle move and the time of operation of the brake, as well as the magnitude of the stroke of the pistons of the brake cylinders.

Brake rim runout is measured with an indicator. If the runout of the brake rim exceeds allowed values, to make its groove.

With significant wear of the brake rim, the latter must be reinforced with special linings or replaced with a new one. The minimum permissible brake rim thickness must be agreed with the manufacturer.

Not allowed excessive heating brake rim. Its t should not exceed 70 0

Excessive heating of the brake rim and press pads also reduces the coefficient of friction between them.

Excessive heating of the brake rims can be caused by poor fit of the brake pads, improper adjustment of the brake actuator, incomplete braking of the machine due to incorrect adjustment of the brake actuator, and bulge of the rim (due to local heating). If excessive heating of the brake rims is caused by the intensive participation of the brake in operating modes, it is recommended to use electrodynamic braking to reduce the participation of the brake.

What car owners do not go to to prevent the theft of their vehicle. The fantasies and ideas of protection are so diverse that they can be applied to almost any system in a car, "directing" its action to work as another obstacle to car theft. The braking system was no exception. At the moment, there are security systems that block the brakes when trying to steal a car. We will talk in more detail about this non-standard use of brakes later.

Operating principle anti-theft system using regular brakes

The algorithm of such an anti-theft system is approximately as follows. In the brake system, after the main brake cylinder, a shut-off and check valve, parallel to each other. At daily operation the shut-off valve is permanently open and the brake system operates in its normal mode. When arming, the shut-off valve closes and the non-return valve starts to work, passing the brake fluid only from the main brake cylinder to the brake cylinders. At the same time, pressing the brake pedal causes one-sided injection brake fluid, without subsequent outflow and drives brake cylinders that are clamping brake pads on disks. Everything, the car is blocked in place, further movement without unlocking the shut-off valve, that is, from "disarming", it is impossible.

The cost of an anti-theft system using standard brakes

The cost of installing such a system is quite high. The thing is that not only additional equipment will be required here, but also a qualified installation, since intervention in the hydraulic circuits of the brake system will be required. The price with installation, depending on the complexity of the system being installed, will start from $900.

Advantages of the anti-theft system using standard brakes

The main advantage of the system is that it will prevent theft, that is, it will perform its main function. Another plus will be the fact that the car, when such an anti-theft system is activated, cannot be towed without full loading to the tow truck. Everything seems to look pretty "colorful" until you think about the cons.

Cons of the anti-theft system using standard brakes

Now for the cons. In fact, there are not so few of them, and even worse, they are decisive when choosing this option to protect the car from theft.

When installing the system, it will be necessary to carry out qualified work on the implementation additional equipment into the vehicle's braking system.

Such interference may affect the limitation of the dealer's warranty, if you have one. When a car thief determines the type of protection system, he will not think long about how to steal a car. It is enough to cut the rubber flexible hoses on the front wheels to depressurize the two diagonal circuits of the car's brake system, while the wheels will become “free”. Yes, driving with a faulty brake system is difficult, but it is POSSIBLE! But "to help" such movement with a faulty brake system will be an emergency hand brake because no one canceled his work.

Mechanical anti-theft protection modern car rather difficult task to implement. Medium and high cars price segment so crammed with electronics that even the previously familiar gearshift lever is almost a touch joystick. All mechanics remain under the hood, and control is carried out through electronic components.

Of the mechanical “transmitters”, only the steering wheel and pedals remained. And if earlier a fairly common way to protect against theft was a gearbox lock that blocked the possibility of gear shifting, now there is nothing to block. At least in the car. Not to mention the rather dubious protection in this way for most car models, because the transmission can be easily and quickly turned on under the hood of the car. Accordingly, the system must be “covered” with an additional hood lock, etc.

Here you can talk for a long time about the pros and cons of electronic protection, protection engine compartment, steering lock and more. But, consider specific example comfortable and optimal protection of the car from theft - blocking the brake system. Outwardly, it looks like this, a keyhole in an inconspicuous place:

Why is a brake lock optimal?

When the brakes are locked, the car will not be able to move under its own power;

If you, for example, forgot to unlock the steering shaft, then there is every chance to go where you did not want to).

There are 3 types of blocking of the brake system on the market (not counting the "grandfather" traps and similar devices that are not convenient to use) Block-Lock, Technoblock, Great Guard.

block lock- brake pedal lock in the car. device with all modern defenses from breaking the blocker itself. Designed for each type of car individually, installed on regular places. Mechanically blocks the movement of the brake pedal itself, so there is no way to even turn on the gear. In the interior of the cabin, only a larva from the key. Installed completely in the car.

Technoblock- mechanical interlock of the brake system of the car. It is installed in a gap in the regular brake line of the car, blocking the release of pressure after pressing the brake pedal. Thus, if the device is armed, when you press the brake pedal, the pads block brake discs and remain in that position. The wheels of the car are stationary. When disarmed, the valve group is unlocked and brake line will operate normally. The device is universal for all types of cars. It is installed partly in the cabin, partly under the hood of the car. To complete the picture, it is desirable to install a hood lock to protect against bypassing the blocker (I will explain: if the hijacker knows or assumes that there is a technoblock system in the car, he will bring with him a set brake pipes and opening the hood will quickly restore the standard highway). In case of a false alarm (pressing the pedal by the user himself without disarming), the pressure in the line can only be relieved in the service condition or by waiting for about two to three hours the system is such that you will not be able to turn the key in the larva, respectively, the valves will not open and the car will remain with locked wheels.In a natural way, the pressure will be released only after a long time of 2..3 hours, or you need to relieve the pressure by unscrewing the brake fittings - as when bleeding the brake system )

Great Guard- according to the principle of operation, it is similar to a technoblock, only it is controlled electronically. An additional hood lock is provided in the kit, since in addition to bypassing the blocker, electronic hacking of the control unit is possible.

BLOCK LOCK BRAKE PEDAL LOCK FEATURES

The blocker is equipped with a Swiss-made KAVA lock cylinder, which is distinguished by its small dimensions, aesthetic appearance, convenient location and versatility of installation in dark or light salons;
the bollard is installed in the passenger compartment on regular places, in the immediate vicinity of the driver on the front panel in convenient location, is controlled by a key and does not require additional manipulations;
the installation of a steering shaft lock greatly complicates the theft of a car, as it perfectly complements the anti-theft systems installed on the car;
in some cases is the only possible mechanical anti-theft device;
in the locked position, the locking bolt prevents the brake pedal from moving, makes it difficult to start the engine, change automatic transmission modes and prevent car theft;
has an enlarged crossbar and an additional trap that protects the crossbar from force impact.

The design of the Block-Lock® brake pedal lock provides protection against force, cutting brackets, breaking out the lock, manipulation of the lock cylinder and other methods of breaking.

DESCRIPTION OF THE BRAKE PEDAL LOCK UNIT LOCK

The brake pedal lock is designed to protect the car from theft.

Installation of anti-theft security complexes Block-Lock® significantly increases the chance of preventing car theft and makes it more difficult for intruders, while the use of simple, effective and easy-to-use devices will protect the car during the absence of the owner.

One of the ways to protect the car from theft is to install a brake pedal lock, which is different effective protection brake pedals from moving in the locked position, the inability to start the engine of some car brands and, accordingly, move the automatic transmission lever from the Parking position. Concealed installation inside the front panel of the car, allows you to maintain high ergonomic qualities, convenience and ease of use. The lock cylinder is located in the immediate vicinity of the driver on the front panel, in a convenient place, is controlled by a key and does not require additional manipulations.

The brake pedal lock consists of a durable steel round body that repeats the shape inner space front panel. A powerful crossbar of increased diameter securely fixes the brake pedal from movement. The blocker is equipped with a lock cylinder made by the Swiss company KABA. The design of the blocker is characterized by increased mechanical strength, which makes it possible to resist possible attempts of force breaking or opening with a tool.

The brake pedal lock is attached to regular places inside the front panel using detachable fasteners. Intermediate bracket allows adjustment of the lock and simplifies installation. Installing a blocker inside the panel makes it much more difficult to try mechanical impact to the blocker.

To bring the blocker to the “closed” position, it is enough to turn the key, while the blocking bolt will securely fix the brake pedal from moving, as a result of which the ability to start the engine and move the automatic transmission lever to the Drive position is blocked.

TECHNICAL FEATURES OF BLOCK-LOCK BRAKE PEDAL LOCKERS

Traditional means mechanical protection car controls are unclaimed as the development electronic systems where, for example, there is an electronic joystick instead of an automatic transmission control lever, and the steering shaft lock does not provide adequate protection.

The brake interlocks presented on the market require highly skilled and careful installation, do not always effectively protect the car from theft, and most importantly, require integration into the standard braking system, worsening braking efficiency and driving comfort.
