Problems solved by technology

The hydraulic cylinder in the car is one of the essential actuators. When the hydraulic cylinder in the car is moving at high speed, the friction between the piston and the cylinder is too fast, which often causes the oil temperature in the cylinder to be too high, and it expands and contracts with heat In the long run, it will lead to poor sealing of the cylinder body, affecting the service life of the car, and once the seal between the piston rod and the guide sleeve leaks or leaks, it will lead to accidents in the use of the hydraulic cylinder

Abstract

The invention discloses an automobile cylinder, the structure of which comprises a cylinder, a hydraulic rod, a pipe joint and a bushing. The spring in the piston rod cooperates with the arc-shaped top bar to solve the problem of excessive friction between the piston and the inner wall of the cylinder when the cylinder is moving at high speed, which often causes the oil temperature in the cylinder to be too high. In order to solve the problem of poor sealing of the body, the pressure plate uses the decontamination mechanism to push the grease on the surface outward, so that the grease is collected by the dirt receiving groove on the retaining ring, and the cylinder is warned by the positioning switch and the signal alarm, and the cylinder is sealed There is a problem of extravasation or leakage, which avoids accidents in the use of the cylinder and improves safety performance.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to an automobile hydraulic cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). The hydraulic cylinder in the car is one of the essential actuators. When the hydraulic cylinder in the car is moving at high speed, the friction between the piston and the cylinder is too fast, which often causes the oil temperature in the cylinder to be too high, and it expands and contracts with heat In the long run, it will lead to poor sealing of the cylinder body, which will affect the service life of the car, and once the seal between the piston rod and the guide sleeve leaks or leaks, it will lead to accidents in the use of the hydraulic cylinder. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention ...
