Problems solved by technology

This kind of brake solves the defects of uneven force and poor braking performance of traditional brake devices
However, the physical contact between the brake disc and the friction plate still exists when the friction plate returns to its position, and there is a certain drag torque, which increases the energy consumption of the vehicle.

Abstract

The invention discloses a quick return structure of an automobile friction plate. The quick return structure aims to overcome the defects that during automobile friction plate return, physical contact between a brake disc and the friction plate still exists, a certain dragging moment exists, and automobile energy consumption is increased. The quick return structure comprises an outer friction plate and an inner friction plate which are oppositely mounted on calipers. A mounting groove is formed in the calipers. The outer side of the outer friction plate is connected with a return elastic piece. The two ends of the return elastic piece are connected to the side wall of the mounting groove. An automobile brake disc is arranged between the outer friction plate and the inner friction plate to rotate. During braking, the outer friction plate and the inner friction plate are close to the brake disc and are attached to the brake disc, and slowdown braking is carried out through friction resistance; and when braking is released, the outer friction plate and the inner friction plate return in the direction away from the brake disc. The outer friction plate bears the action of pulling force of the return elastic piece when returning, returning of the outer friction plate is accelerated, the outer friction plate and the brake disc are separated fast, the dragging moment is greatly reduced, and automobile energy consumption can be reduced easily.

Description

technical field [0001] The invention relates to an automobile friction lining, more specifically, it relates to a quick return structure of the automobile friction lining. Background technique [0002] At present, the return of the friction plate on the traditional floating brake caliper is mostly achieved by the thrust on the friction plate generated by the end jump of the brake disc itself, but this return method still has the friction between the brake disc and the friction plate. There is a certain drag moment in the physical contact. With the continuous popularization of electric vehicles, the cruising range has become an important performance index of electric vehicles. There are many factors that affect the cruising range of electric vehicles. The drag torque of automobile brakes is one of them. Reducing the drag torque of brakes by 1N m can reduce 0.5 %-1% energy consumption, so reducing the brake drag torque has positive significance for the cruising range of the v...
