Shock absorber for automobile

Abstract

The invention discloses an automobile shock absorber, which comprises an inner cylinder and an outer cylinder, an oil storage chamber is formed between the inner cylinder and the outer cylinder, and part of high-pressure gas is arranged inside the oil storage chamber, and the inside of the inner cylinder There are seals, separation pistons, overflow valves, action pistons and bottom valves in order from top to bottom, and an oil seal is provided on the end of the inner cylinder close to the seals, and the bottom of the oil seal is connected to the seal A guide is provided between the parts, and a piston rod is interspersed in the inner cylinder, and the piston rod passes through the oil seal, the guide, the seal, the separation piston and the overflow valve in sequence and Fixedly connected with the moving piston, an annular groove is provided on the inner wall of the inner cylinder near one end of the guider, and an annular protrusion is arranged on the inner wall of the inner cylinder and inside the annular groove. Beneficial effects: the invention has good shock absorption and buffering effect, long service life and stable structure.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile shock absorber. Background technique [0002] Automobile shock absorber is a shock-absorbing device for automobiles. In order to quickly attenuate the vibration of the frame and body and improve the ride comfort and comfort of the car, the automobile suspension system is generally equipped with shock absorbers. It can cushion the pressure generated by the spring when bumping, making the car run more smoothly. From the perspective of damping materials, shock absorbers are mainly divided into hydraulic and pneumatic. There is also a shock absorber with variable damping. The principle of hydraulic shock absorbers is: when the frame and the axle make reciprocating relative motion, the piston When moving back and forth in the cylinder barrel of the shock absorber, the oil in the shock absorber housing will repeatedly flow from the inner cavity through some narrow pores into an...

AI Technical Summary

Problems solved by technology

The traditional hydraulic shock absorber can provide better shock absorption and buffering effect when the car bumps are small, but when the car encounters a road section with large bumps, it cannot achieve the expected shock absorption and buffering effect, so that the car cannot Moving forward smoothly, the existing hydraulic shock absorber has poor shock absorption effect, short service life and unstable structure
