Abstract

The invention provides a brake piston, a brake and a hydraulic motor, and relates to the technical field of hydraulic systems. The brake piston comprises a plug body; and the plug body is provided with a first end surface along the axial direction of the plug body, and limiting parts are arranged on the first end surface. After the plug body is assembled into a shell of the brake, a spring is arranged between the first end surface and a shell end cover, when the plug body moves towards the end cover, the plug body compresses the spring until the limiting parts make contact with the end cover,the compression amount of the spring can be limited, the compression amount of the spring is prevented from being too large, and the service life of the spring is prolonged. Due to the fact that the limiting parts are arranged on the first end surface, the radial size of the plug body is not increased, moreover, the axial stroke of the plug body is certain, the limiting parts are arranged on the first end surface and the axial size of the shell can not be increased, the size of the brake can be reduced, increasing of the size of the hydraulic motor can be avoided, and the power ratio of the hydraulic motor can be improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic systems, in particular to a brake piston, a brake and a hydraulic motor. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Liquids are media that transmit force and motion. [0003] Most hydraulic motors have hydraulic brakes inside, which are used to brake the hydraulic motor quickly and smoothly. The hydraulic brake in the prior art includes a housing and a brake piston, the brake piston is arranged in the housing, and a spring is arranged between the housing and the brake piston. [0004] In order to limit the compression amount of the spring, a limiter is provided on the annular side wall of the brake piston, and the limiter cooperates with the inner wall of the housing to limit the compression amount of the s...
