Problems solved by technology

[0004] However, with the rapid development of the automobile industry and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort of the car. However, due to the limitations of the traditional damping shock absorber structure, the damping value is relatively simple, so it is no longer possible. Adapt to market demand

Abstract

The invention discloses a shock absorber. The shock absorber comprises a working cylinder, an oil storage cylinder arranged at the outer side of the working cylinder in a sleeving manner, a compression valve system arranged at the bottom of the working cylinder, a piston rod connected in the working cylinder in a sleeved manner and a recovery valve system arranged at the bottom of the piston rod, and is characterized in that a guider is further arranged between the working cylinder and the oil storage cylinder; and an adjusting valve is further arranged corresponding to the guider, the adjusting valve comprises a valve cavity and a valve element, at least one section of the valve element is located in the valve cavity and arranged to be in a spiral curved surface shape, and the side wall of the section, arranged to be in the spiral curved surface shape, of the valve element is matched with a first channel opening or / and a second channel opening of the adjusting valve to achieve opening adjustment of a valve body. According to the shock absorber, the damping magnitude is adjusted by controlling the flowing volume of oil liquid, so that the requirement of a user for suspension comfort is met.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a shock absorber. Background technique [0002] In the automobile suspension system, since the elastic elements (such as shock-absorbing springs) also have reciprocating motions when filtering road vibrations, in order to improve the ride comfort of the car, shock absorbers are usually installed in the suspension system to suppress The shock when the spring rebounds after absorbing the shock. [0003] At present, most of the shock absorbers used in automobile suspension systems are hydraulic cylinder shock absorbers. The working principle of this hydraulic cylinder shock absorber is that when there is relative movement between the frame and the axle due to vibration, the The piston rod in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to the other, so that the relative motion between the shock absorber p...
