Single-action brake wheel cylinder

Abstract

The invention discloses a single-action brake wheel cylinder. The single-action brake wheel cylinder 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 double oil inlets; a stifle is covered on the oil inlets respectively; left and right adjustment pistons are arranged at the left and right ends of the cavity in a sliding way; one end of each adjustment piston is arranged in the cavity in a sliding way, and the other end of each adjustment piston is provided with a limit flange; the outer end face of the left adjustment piston is fixedly provided with an adjusting screw; annular clamp grooves are formed on the side walls of the adjacent ends of the left and right adjustment pistons; leather collars are clamped in the annular clamp grooves; the leather collars is in tight fit with the side wall of the cavity; the outer wall of the cylinder body is fixedly provided with a lock plate; the outer wall of the cylinder body is provided with an installation disk; the four corners of the installation disk are provided with installation holes; and the side wall of the cylinder body is provided with a bolt installation hole and a limit hole. The single-action brake wheel cylinder has a reasonable and simple structure and the working efficiency of the brake wheel cylinder is improved.

Description

technical field [0001] The invention relates to a single-acting brake wheel cylinder. 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. The structural performance of the wheel cylinder directly ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art, and provides a single-acting brake wheel cylinder assembly, which solves the problem that in the automobile brake system, the gap between the piston and the working chamber of the wheel cylinder cannot be adjusted, and the piston is in the wheel cylinder. The position in the working chamber is not well controlled, which affects the work efficiency, and the structure of the external fixed installation parts is unreasonable, resulting in unstable installation, and at the same time, the sealing between the piston and the cylinder is not good, resulting in oil leakage and other problems
