Description
Technical Field
The utility model belongs to the technical field of car braking support, concretely relates to car braking support that low sound of preventing takes place.
Background
Automotive brake systems tend to emit a low frequency chirp. The brake low-squealing noise is a single-frequency brake noise, the sound pressure level can reach more than 90dB (A), the sound frequency is low, generally 300Hz-600Hz, the sound is generated to be unacceptable, the user is caused to be strongly discontented, and the brake low-squealing noise is a problem to be avoided in the design of a brake system.
The low brake squeal is caused by the resonance of the brake and the suspension system caused by the excitation of dynamic friction force between the brake lining and the brake disc, and although the suspension and the brake system structure are involved in the resonance, the contribution amount of the brake bracket to the vibration is generally large, and when the vibration transmission characteristic of the brake bracket is not reasonable, the obvious low squeal noise is easy to occur. Therefore, an important measure for preventing the brake low noise is to reasonably design the vibration transmission characteristics of the brake bracket so that the vibration generated by the dynamic brake friction excitation can be well isolated from being transmitted to the suspension and the vehicle body, thereby avoiding the generation of the brake low noise. The traditional automobile brake support structure design mainly considers performances such as brake transmission force, structural strength and the like, generally does not consider the influence of dynamic transmission characteristics of the support on brake low noise, and easily generates the brake low noise.
