Noise reduction and active return structure of friction plate

Abstract

The invention relates to a noise reduction and active return structure of a friction plate. The noise reduction and active return structure mainly comprises a support and the friction plate. Convex blocks at the two ends of the back of the friction plate are embedded into grooves at corresponding positions of the support. A rubber part is arranged on each convex block. The convex blocks are in contact with the grooves through the rubber parts. The rubber parts are in interference fit with the grooves of the support. The friction plate is in contact with a brake disc through piston pushing. Thenoise reduction and active return structure has the beneficial effects that the rubber parts are additionally arranged, the function of active return of the friction plate is achieved, and thereforethe dragging torque of a brake is reduced, and oil consumption of an automobile is reduced; compared with other design, the friction plate has no extra return spring structure, mounting is convenient,and maintenance is easy; and the rubber parts and the support are in interference contact, and the problem of noise of the friction plate is solved.

Description

technical field [0001] The invention relates to the structure of a friction plate, in particular to a friction plate noise reduction and active return structure. Background technique [0002] The back plate of the existing friction plate is made of steel and is in rigid contact with the bracket. It is easy to collide with the bracket to generate noise during driving, and it does not have the function of active return. The friction plate does not have the function of actively returning to its position after the car brakes. It needs to be thrown away by the centrifugal force of the brake disc. The drag torque of the product is relatively large, and the fuel consumption of the car increases. Contents of the invention [0003] The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a friction plate noise reduction and active return structure with simple structure and stronger practicability. [0004] The technical solution adopted b...
