Abstract

The invention provides a low-eccentric wear steel back structure, and belongs to the technical field of measurement braking. The low-eccentric wear steel back structure comprises a strip-shaped steelback which is in a plate shape, both the two ends of the steel back in the length direction are provided with an externally-hung side lug, wherein one of the two externally-hung side lugs is long, andthe other one of the two externally-hung side lugs is short; and meanwhile, a friction plate is arranged on one side of the steel back, and a piston is arranged on the other side of the steel back. According to the low-eccentric wear steel back structure, the long and short externally-hung side lugs are arranged, on the condition that the total length of the friction plate and the length and installation of supports including a caliper, a shell and the like are not changed, excursion of the stress center axis of the piston is realized, so that eccentric wear of the friction plate in the circumferential direction is reduced, meanwhile, the radius of the friction plate corresponding to the projection on the friction plate of the position of the stress center axis of the piston meets the optimal stress center point position formula of the friction plate, eccentric wear of the friction plate in the radial direction is reduced, the service life of the friction plate is prolonged, braking noise caused by dragging and shaking is avoided, and the performance of a braking system is improved overall.

Description

technical field [0001] The invention relates to the technical field of measuring braking, in particular to a steel back structure with low eccentric wear. Background technique [0002] At present, all vehicles are equipped with a braking system, and the braking system achieves braking through friction between the friction plate and the brake disc. Due to the rotation of the brake disc, the partial wear of the friction plate is caused. Therefore, the current brake The problem of eccentric wear has become the focus of attention in the vehicle braking industry today. [0003] Traditionally, the size of the lugs on both sides of the friction plate steel back of the friction plate is equal, resulting in equal areas of the two sides of the friction plate on the central axis of the force, resulting in large radial eccentric wear and circumferential eccentric wear, which affects both The service life of the friction plate will also bring drag and jitter, produce automatic noise, an...
