Pneumatic disc anti-lock brakes

Abstract

The invention provides a pneumatic disc type anti-lock brake, the structure of which includes two sets of brake assemblies arranged symmetrically on both sides of the brake disc, each set of brake assemblies includes a cylinder body, a brake pad, a piston, an end cover, a disc Bolts, springs and flat pads. The inner cavity of the cylinder is provided with an end cover, a piston and a brake pad in sequence from the outside to the inside. The brake pad and the piston are connected together. The rear rod end of the piston is provided with a disc bolt. The inner side of the rear rod is provided with a flat pad used as a compression block, and a spring is installed on the rear rod of the piston between the disc bolt and the flat pad, and an air cavity is formed between the piston and the flat pad. After the braking action is completed, the spring at the rear end of the piston automatically separates the brake pad from the brake disc. Unlike the previous BDF brake, which relies on the inertia of the motor itself to separate the brake after the brake is completed, this invention will not lock the brake when the motor starts. , can double the life of the brake pads, and will never damage the motor and brake disc due to the problem of the brake pads not returning.

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...
