Description

Shock absorber to reduce shock absorber noise

Technical Field

The utility model relates to the technical field of shock absorbers, in particular to a shock absorber for reducing the noise of the shock absorber.

Background Art

Shock absorbers are used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car. When the piston reciprocates in the cylinder, the oil in the shock absorber flows back and forth between the two mutually isolated inner cavities through the narrow pores on the valve. Due to the friction between the pore wall and the oil and the internal friction of the liquid molecules, a damping force is formed, thereby converting the mechanical energy of the body vibration into heat energy which is absorbed by the oil and the shell.

When the existing shock absorber is in use, piston movement is performed between the piston rod in the shock absorber and the hydraulic cylinder body, and the piston and the inner wall of the hydraulic cylinder body will repeatedly rub against each other. When the inside of the cylinder body contacts dust, the lubrication effect will be deteriorated, which will not only emit a loud noise, but also affect the shock absorbing effect and service life of the shock absorber. In order to solve the shortcomings of the existing technology, we propose a shock absorber that reduces the noise of the shock absorber.
