Problems solved by technology

And the existing shock absorber consists of a cylinder body, a piston located in the cylinder body, a piston rod whose inner end is connected to the piston, a bottom valve located at the bottom of the cylinder body, a top valve located at the top of the cylinder body, and a piston rod located at the cylinder body top. The bottom cover at the bottom of the body, the support rod, and the suspension ring. The damping strength of the shock absorber cannot be adjusted, and it can only adapt to a single road condition, and cannot be adjusted according to different road conditions. The shock absorption effect is poor, and it cannot adapt to different road conditions.

Abstract

The invention relates to the field of automobile accessories, and in particular to a both-way damping adjustable shock absorber. The both-way damping adjustable shock absorber comprises a work cylinder, a piston arranged in the work cylinder, a piston rod with the inner end connected with the piston, an oil returning pipe arranged outside the work cylinder in a sleeving manner, and an oil storage barrel arranged on the outer side of the oil returning pipe in a sleeving manner. A bottom valve is arranged at the bottom of the work cylinder and the bottom of the oil returning pipe. A guiding device is arranged at the upper end of the work cylinder and the upper end of the oil returning pipe. A fastening cover is arranged at the upper end of the oil storage barrel. A bottom cover is arranged at the lower end of the oil storage barrel. The both-way damping adjustable shock absorber is characterized in that a mechanical adjustable rotary knob is arranged on one side of the bottom cover, an adjusting hole is formed in the bottom cover, and the mechanical adjustable rotary knob is arranged in the adjusting hole; and an oil collecting trough is formed in the combination end of the bottom cover and the bottom valve, and a connecting channel for the adjusting hole and the oil collecting trough to be communicated is arranged in the bottom cover. The damping strength of the shock absorber can be adjusted, the both-way damping adjustable shock absorber can adapt to different road conditions and is good in damping effect and simple in structure, and the damping performance can be adjusted according to different road conditions.

Description

technical field [0001] The invention relates to an automobile shock absorber, in particular to a two-way damping adjustable shock absorber. Background technique [0002] In recent years, with the rapid development of the automobile industry, especially the car industry, shock absorbers, which are important parts of automobiles, have also developed rapidly. Automobile shock absorber is a kind of damping element and one of the important components of automobile suspension system, which plays a decisive role in the ride comfort, comfort, safety, steering operability and passability of the vehicle. And the existing shock absorber consists of a cylinder body, a piston located in the cylinder body, a piston rod whose inner end is connected to the piston, a bottom valve located at the bottom of the cylinder body, a top valve located at the top of the cylinder body, and a piston rod located at the cylinder body top. The bottom cover at the bottom of the body, the support rod, and t...
