The invention relates to brake mechanism of the vehicle, in particular to a disk or drum brake mechanism containing fixed on the supporting plates of the brake linings and the tension device.

Brake linings of cars are prone to wear parts and therefore should be replaced with a certain degree of wear. Manufacturers of trucks advised car owners to comply with certain requirements. One of these requirements is that all brake linings car had the same coefficient of friction. Often this requirement is not observed, as in the workshops are not supplied by the manufacturer of the truck brake linings, and also by the manufacturers supplying brake linings low quality.

The basis of the invention is to create such a brake mechanism of the above described type for vehicles, so at least when replacing the brake linings was evident whether the brake linings safety requirements, even in the case when after replacing the brake linings are used in brake linings, on which there is no resolution of the manufacturer of the brake mechanism on the application, but which, due to homologation you have permission from the Federal office for motor traffic for the application.

The problem is solved in that at least one pad brake pads brake mechanism of the vehicle equipped with the electronic unit is equipped with, at least, to remember specific regarding pads brake pads electronic data storage device.

The invention also created brake system with brake mechanism of the vehicle, characterized in that it is designed in such a way that specific on the brake linings data is additionally processed in the electronic unit brake control unit of the brake system of the vehicle, the data include specific regarding the brake linings parameters such as quality of manufacture, the surface linings of the brake pads or friction factor influencing the braking action. In the very simplified direct use of specific concerning brake linings data, which significantly increases the safety of the braking system, as, for example, can separately managed individual wheels when required brake linings, without requiring a preliminary determination of specific concerning brake linings parameters (for example, by means of which sensibilizatsii).

Specific on the brake linings, data can be entered in the electronic unit from the manufacturer of the brake linings or the manufacturer of trucks. When replacing brake linings and pads of the readout device and data processing determines are necessary to ensure the safety of specific concerning brake linings data and what additional data is present (for example, date of manufacture, the coefficient of friction, surface pads brake pads etc). Control pads brake pads is carried out in a contactless manner and without the external examination. The electronic unit also denoted as radiotime, radiotechnic, smart label or tag.

According to a preferred variant of execution of the electronic unit consists of a chip of the radio frequency identification containing the memory, the processor and transmitting unit for transmitting signals. The size of the chip RFID are relatively small, which allows the manufacture of brake linings and pads it can be it built-in. Alternatively, it can also be pasted at the appropriate place pads brake pads.

The spatial arrangement of the readout device and processing data on the electronic unit can be the t to vary. So according to the first variant implementation is provided to the power electronic unit was due to the electromagnetic field of the reading device and data processing. With this arrangement, the readout device and data processing must be, however, in the immediate vicinity of the brake mechanism of the vehicle or located directly on the brake mechanism. Because removal of the electronic module from the instrument readout and data processing power is no longer possible due to the electromagnetic field, power electronic unit the latter is also equipped with a voltage source. As such source is preferably a rechargeable battery.

For receiving the transmitted electronic control unit signals the device for receiving and processing data equipped with an antenna. Particularly, it is preferable to position the antenna on the brake caliper or perform the brake caliper in the form of the antenna. However, alternatively, the antenna can be installed on the card recognition system wear.

Also in relation to the location of the readout device and data processing there are different possibilities. For example, according to a preferred variant implementation is provided to the readout device and processing the data and was located inside the brake mechanism or inside the car. Location inside the vehicle has the advantage that it provides easy access.

Typically, anti-lock braking system equipped with trucks. Therefore, it is also possible to set the readout device and data processing in the control unit anti-lock braking system. In particular, in trucks, the readout device and data can be installed in the control unit.

Radioactice, Radiotechnika, smart labels, or labels used in the so-called radio frequency identification. Therefore, to solve this problem is proposed using a RFID system for recognizing pads brake pads brake mechanism of the vehicle, in particular in commercial vehicles, with evidence of restrictive part of paragraph 1 of the claims.

This system is replaced, for example, a bar code.

The invention relates to the lining of the brake pads on paragraph 8 of the claims.

In the brake system that contains the brake mechanism of the vehicle of the type indicated above, may be provided in accordance with the preferred execution to specific concerning the brake linings data were processed additionally in e th the e by the control unit of the brake system of the vehicle, the data contain specific regarding the brake linings parameters, such as, at least, the quality of manufacture, the surface of the brake linings or friction, since these parameters affect the braking effect.

To improve this braking system may also include data about the manufacturer, such as date of production, batch production, location production companies, etc. as a result, when problems arise regarding the quality of the manufacturer can be specifically identified the appropriate brake linings. For this purpose up to the present time on the back plate of the brake linings are the relevant data. This has the disadvantage that in the case of replacement or revocation by the manufacturer of the brake linings requires removal of all plates and validation. Because of this there are relatively high costs and in many cases marking is no longer visible. Using labels corresponding data may be included in memory device is read and data when installing the brake linings and, for example, be stored centrally in the vehicle. This memorization can be done in the electronic unit. Preferably, when ativana trip computer eliminated the need for a separate check. Even if the label has disappeared due to overheating during operation of the brake mechanism, the problem does not occur with centralized accounting data.
