Abstract

The invention discloses a wheel cylinder for automobile, which comprises a cylinder body. The cylinder body is provided with a chamber. A deflating bolt and an oil inlet are communicated on the side wall of the chamber. A deflating cap is arranged at the top end of the deflating bolt. Left and right pistons are respectively installed at left and right ends of the chamber in a sliding way. Left and right packing leather are respectively arranged on adjacent surfaces of the two pistons. The packing leather is fixedly installed on one of side walls of the left and right pistons respectively. The packing leather is adhered tightly to the side wall of the chamber. Spring bases are fixedly installed on the end surfaces of the packing leathers. A spring is locked between the two spring bases. The wheel cylinder has a simple and reasonable structure, and is hermetical and dustproof effectively.

Description

technical field [0001] The invention relates to an automobile 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 affects ...
