The method can quickly and effectively predict the wear condition of the brake friction plate.
Description
technical field [0001] The invention belongs to the technical field of automobile brakes, and relates to a method for analyzing the wear of automobile brake friction plates. Background technique [0002] As one of the key components in the automobile brake system, the friction plate plays a key role in ensuring the safe driving of the automobile. When the car brakes, the contact surface between the brake disc and the friction pads in the brake system will experience severe friction. During the friction process of the braking interface, wear will inevitably occur, and the amount of wear of the friction pads It directly affects the service life of the friction plate, which is related to the braking safety of the car. Therefore, it is of great significance to study the wear of automobile brake friction plates. However, the existing methods for analyzing the wear of automobile brake friction plates cannot quickly and effectively predict the wear conditions of automobile brake ...
