Problems solved by technology

Although springs are housed in the cylinder to pull the piston protruding from both ends of the cylinder back into the cylinder to stop braking the wheels of the car, the spring will be deformed after being pulled many times, so that the piston is pulled The direction of pulling force is deflected, resulting in the rebound of the piston is not smooth enough, and once the spring is damaged, the braking function of the two pistons at both ends will be affected at the same time, posing a potential safety hazard

Abstract

The invention discloses a brake single-wheel cylinder. The brake single-wheel cylinder comprises a cylinder body (1) with an opening in one end, a spring (2)and a piston (4); a cavity is formed in the cylinder body (1); the piston (4) is slideably arranged in the cavity, and divides the cavity into an oil cavity and a slide cavity; an oil inlet is formed in the cylinder body (1), and is communicated with the oil cavity through an oil inlet channel; the spring (2) is arranged in the oil cavity, one end of the spring (2) is fixedly connected to the piston (4), and the other end of the spring (2) is fixedly connected to the side wall of the oil cavity; a Y-shaped sealing ring (3) is arranged on the outer wall of the piston (4) in the peripheral direction; and the piston (4) is connected with a vehicle brake shoe through a push rod. The brake single-wheel cylinder can synchronously and singly brake wheels, and improves the safety of a brake system.

Description

technical field [0001] The invention relates to an automobile brake system, in particular to a brake single wheel cylinder. Background technique [0002] The automobile brake wheel cylinder is installed in the automobile wheel disc and is used for the braking of the automobile. It is an important device to ensure the safety of the automobile. Generally, the common hydraulic brake wheel cylinder is usually used in the automobile, which generally includes a cylinder body and a piston. , Spring nozzle, etc. [0003] Two pistons are installed inside the existing brake wheel cylinder, and the two pistons are respectively connected with the brake shoes on the wheels on both sides of the automobile through pull rods to brake the wheels. Although springs are housed in the cylinder to pull the piston protruding from both ends of the cylinder back into the cylinder to stop braking the wheels of the car, the spring will be deformed after being pulled many times, so that the piston is ...
