Description

Multichannel shock absorber

Technical Field

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

Background

In the working condition environment requiring buffering or damping, the shock absorber is generally adopted to consume impact energy to realize the effect of buffering and damping, such as automobile damping, elevator damping and the like. When the shock absorber is applied to shock absorption of automobiles, mainly when automobiles pass over uneven pavement, the shock absorption springs are used for filtering the vibration of the pavement, but the springs can do reciprocating motion, and the shock absorber is used for restraining the spring from jumping. Therefore, the shock absorber bears the tasks of buffering impact and shock absorption, the damping force is too large, the elasticity of a suspension is deteriorated, even the shock absorber connecting piece is damaged, most of the shock absorbing devices used on the existing automobile are hydraulic shock absorbers, namely, an inner cylinder and an outer cylinder are utilized, the outer cylinder is an oil storage cavity, the inner cylinder is a working cylinder, parts of the shock absorber are more, and the damping force is unstable. Meanwhile, most of the existing shock absorbers are single-channel shock absorbers, namely hydraulic oil or nitrogen of a cylinder body is compressed through a solid piston, so that the reliability of the shock absorbers in the case of violent impact in a short time cannot be guaranteed, and the phenomenon that the cylinder body bursts or is damaged easily occurs.
