Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0016] Such as figure 1 — image 3 As shown, the present invention includes a friction plate body 1 , and a sound-absorbing plate 2 is attached and fixed on the side of the friction plate body 1 . There is a chute 3 on the other side of the friction plate body 1 opposite to the sound-absorbing plate 2, and the angle α between the chute 3 and the vertical center line on the side of the friction plate body 1 where it is located 35°-65°, the depth h of the chute 3 is 7.7mm-11.7mm, the width d of the chute 3 is 2mm-4mm; both ends of the friction plate body 1 are provided with mutually symmetrical chamfers 4. The bevel angle β of the chamfer 4 is 15°-25°, and the width D of the chamfer 4 is 17mm-26mm.

Abstract

The invention relates to a friction sheet structure for improving brake noise, and belongs to the technical field of auto parts. The friction sheet structure comprises a friction sheet body of which the side face is fixedly provided with a silencing sheet in a fitting way, another side face, opposite to the silencing sheet, on the friction sheet body is provided with a chute, and two ends of the friction sheet body are provided with chamfers which are mutually symmetrical. According to the friction sheet structure, the structure is simple; by changing the inherent frequency of the friction sheet, the noise can be better insulated, low frequency noise is reduced, the braking performance can not be influenced, and the noise reduction effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a friction plate structure for improving braking noise. Background technique [0002] With the improvement of consumers' requirements for car comfort, brake noise has attracted more and more attention from car manufacturers and consumers. Friction pads with low-metal or semi-metal formula are widely used in vehicles due to their superior braking performance and low cost, but the friction pads in the prior art have relatively high braking noise. Contents of the invention [0003] The object of the present invention is to provide a friction plate structure that improves braking noise against the defects of the prior art. [0004] The technical solution adopted by the present invention is: it includes a friction plate body, the side of the friction plate body is attached and fixed with a sound-absorbing plate, and the other side of the friction plate body opposite ...
