Air-compression disc-type anti-lock brake

Abstract

The invention provides an air-compression disc-type anti-lock brake which structurally comprises two sets of brake components symmetrically arranged on two sides of a brake disc. Each brake component comprises a cylinder, a brake pad, a piston, an end cover, a disc bolt, a spring and a flat gasket, the end cover, the piston and the brake pad are sequentially arranged in an inner cavity of the cylinder from outside to inside, the brake pad is linked with the piston, the disc bolt is arranged on the end portion of a back rod of the piston, the flat gasket used for pressing a stop body is arranged on the inner side of the back rod of the piston, the spring is mounted on the back rod of the piston between the disc bolt and the flat gasket, and an air cavity is formed between the piston and the flat gasket. When braking action is completed, the brake pads are automatically separated from the brake disc through the springs at the rear ends of the pistons; different from a conventional BDF brake in which brake parts are separated by depending on inertia of a motor after braking is completed, the air-compression disc-type anti-lock brake has the advantages that brake locking is prevented when the motor starts, service life of the brake pads can be doubled, and the motor and the brake disc are absolutely prevented from being damaged due to the fact that the brake pads do not return.

Description

(1) Technical field [0001] The invention relates to a brake, in particular to an air pressure disc type anti-lock brake. (2) Background technology [0002] The BDF brakes in the prior art rely on the inertia of the motor to separate the brakes after braking, so the brake pads will cause wear to the brake disc after each braking, adding extra load to the motor, and the brake pads will also wear excessively. When the brake is working in a dusty environment, because the dust enters the gap between the brake pad and the cylinder body, after a long time of work, the brake pad will get stuck and fail to return, and it will cause a heavy load to start when the motor is powered on, causing the motor to overload and burn out! (3) Contents of the invention [0003] The technical task of the present invention is to provide an air pressure disc type anti-lock brake aiming at the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve i...
