Abstract

The invention discloses a wheel cylinder assembly. The wheel cylinder assembly comprises a cylinder body; a cavity is formed in the cylinder body; the side wall of the cavity is communicated with a bleed screw and an oil inlet screw; left and right pistons are arranged at the left and right ends of the cavity in a sliding way; adjacent surfaces of the left and right pistons are provided with left and right circular bosses; springs are clamped between the left and right circular bosses; the side walls of the two pistons are provided with grooves; leather collars are embedded in the grooves; and the left and right outer end faces of the two pistons are provided with a cavity respectively. The wheel cylinder assembly has a reasonable structure and is good in sealing performance.

Description

technical field [0001] The invention relates to a wheel cylinder assembly. Background technique [0002] A brake is a device that has the functions of decelerating, stopping or keeping a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machine. Commonly known as brakes, brakes. The brake is mainly composed of frame, brake parts and operating device. Some brakes are also equipped with an automatic adjustment device for the clearance of the brake parts. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), it should be installed on the low-speed shaft close to the working part of the equipment. . [0003] The wheel cylinder is an important part of the brake, and the structural performance of the wheel cylinder directly affects...
