Abstract

The invention discloses a braking noise preventing device of a brake. The braking noise preventing device comprises calipers. A piston, a piston cap, an inner friction plate, a brake disc and an outer friction plate are fixedly mounted in the calipers in sequence. The piston cap comprises a body, a clamping foot and an elastic piece. The clamping foot is connected to the edge of the body which is provided with a through hole, one end of the elastic piece is connected to the edge of one side of the through hole, and the other end of the elastic piece is a free end. According to the braking noise preventing device, the piston cap is added, so that a force transfer path between the piston and the friction plates is changed, damping is increased, vibrating noise of a specific frequency is restrained, and the comfort of a whole car is improved.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a brake noise prevention device for brakes. Background technique [0002] At present, after the caliper brakes under force, the brake disc, caliper, and friction plate are coupled with each other, which may generate braking noise and cause complaints from users. In order to increase user comfort, it is necessary to eliminate this braking noise. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a brake noise prevention device, which changes the force transmission path between the piston and the friction plate by adding a piston cap, increases damping, and suppresses specific frequencies. The vibration noise increases the comfort of the vehicle. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: a brake anti-braking noise device, inc...
