Brake pad disc brake

 

(57) Abstract:

Usage: in brake mechanisms of the vehicle. The inventive brake pad consists of a base plate and friction linings. In the friction pad is made a groove 3, parallel straight side edges of the pad and offset from the axis of symmetry of the pad. 3 Il.

The invention relates to mechanical engineering, in particular to the brake mechanisms of the vehicle, and can be used in the brake control of the vehicle.

Known disk brake mechanisms of the vehicle that contains the brake pads in the form of a support plate with reformirovannoy friction lining having on the working surface of the groove parallel to the side edges of the pad and located symmetrically with respect to them [1] This groove is intended for destruction of a water film formed between the plate and disc while driving on a wet road.

When pressure in the brake system is pressing the brake pads to the disc than is provided by the braking of the vehicle. In the process of braking contact of the friction lining disk vibration occurs, the result is structures brake piston, clamping the block to the disk, and the block set protivogribnye plates, which are designed to have an elastic (usually rubber) element mounted on the base metal.

This solution has drawbacks: the fragility protivozobnyj plates, the increase in the cost of goods and labor services. In addition, even in case of partial wear protivozobnyj plates there is the creaking of individual modes of inhibition. Moreover, the range squeak increases as wear plates.

The aim of the invention is to reduce the level of squeaking brakes on all modes of braking when the vehicle is moving, as well as a significant reduction in product cost, reducing the complexity of the service operation and longer life of brake pads for passenger cars and trucks.

This goal is achieved by the fact that the brake pads containing the support plate and the friction plate, the friction pad is made a groove and the axis of the groove parallel straight side edges of the pad and offset from the axis of symmetry of the pad.

In Fig.1 shows a view of the brake pads in plan; Fig. 2 is a view of the pad from the top of Fig. 3 what was the pad with the groove 3, forming a brake pad. In the disk brake plate 1 plate 2 are mounted on both sides of the brake disc 4.

The device operates as follows.

In brake mechanism installed brake pads, and the grooves 3 of the plates 2 due to their offset from the axis of symmetry pads are arranged asymmetrically. When braking vehicle plate is pressed against the disk and vibrations.

Vibration plates have the same magnitude, but opposite in character actions, and due to the asymmetric location of the groove is superimposed on the other and damping. This action prevents vibration pads, causing the squeal of brakes."

The presence at the plate asymmetrically located groove and the exclusion of the mirror location of the slots relative to the brake disk allows to draw a conclusion about the novelty of technical solutions.

In the search results on the major and related fields other solutions with similar features are not detected, indicating the presence of an inventive step in the claimed solution.

The tests have shown high efficiency of the brakes, as well as raising their $ who>Brake pad disc brake, contains the base plate and the friction pad, characterized in that the friction pad is made a groove and the axis of the groove parallel straight side edges of the pad and offset from the axis of symmetry of the pad.
