Automobile two-way acting cylinder shock absorber

Abstract

The invention discloses an automobile two-way acting cylinder shock absorber. The automobile two-way acting cylinder shock absorber includes a connecting rod, a guide holder, a working cylinder barreland an oil storage cylinder barrel. The top end of the working cylinder barrel and the top end of the oil storage cylinder barrel are connected with the guiding holder, and the bottom end of the working cylinder barrel and the bottom end of the oil storage cylinder barrel are connected with a lower support. The external diameter of the working cylinder barrel is smaller than the internal diameterof the oil storage cylinder barrel. The bottom end of the connecting rod is located in the working cylinder barrel, the bottom end of the connecting rod is connected with a damping assembly, and thetop end of the connecting rod penetrates through the guiding holder to be connected with an upper support. The top face of the guiding holder is provided with a groove, and the groove is internally and disassembly connected with a sealing ring. According to the automobile two-way acting cylinder shock absorber, an elastic component and a piston which are made of metal rubber are adopted, the requirements for the cleanliness of the absorber and the surface roughness of the connecting rod are greatly lowered, and the production cost is reduced; and meanwhile, the automobile two-way acting cylinder shock absorber has the characteristics of sealing reliability, high / low temperature resistance, an oil self-filtration regeneration function, a simple structure and the like.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a two-way acting cylinder shock absorber for automobiles. Background technique [0002] The automobile shock absorber is the main component that generates the damping force, its function is to accelerate the attenuation of the vibration of the body and the frame, and improve the ride comfort of the automobile. At present, the shock absorbers used in automobiles are mainly double-acting cylinder hydraulic shock absorbers, which can work in both compression and tension strokes, and the damping force generated in the stretching stroke is much greater than that generated in the compression stroke . [0003] Traditional automobile shock absorbers use single-edge or double-edge rubber as oil seals. Since the shock absorber is installed in the suspension system of the automobile chassis and the working environment is dirty, it generally requires a fatigue life of at least 1 million...

AI Technical Summary

Problems solved by technology

Therefore, the traditional automobile shock absorber connecting rod surface roughness processing, assembly cleanliness and other technical requirements are high, resulting in high production costs. In addition, there are disadvantages such as poor high / low temperature adaptability caused by rubber seals, and complex piston structures.
