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 ride comfort of cars, and shock absorbers with a single damping value can no longer meet people's needs. Then it came i

Abstract

The invention discloses a double-adjustable-damping shock absorber which comprises an inner cylinder barrel and an outer cylinder barrel. An inner cavity of the inner cylinder barrel serves as a working cylinder, a reserved gap between the inner cylinder barrel and the outer cylinder barrel serves as an oil storage cylinder, the upper end of the outer cylinder barrel is connected with the upper end of the inner cylinder barrel in a sealed mode through a guider, a piston rod is inserted into the guider, a recovery valve system is arranged at the lower end of the piston rod, and a recovery adjusting mechanism used for adjusting the oil flow volume between an upper working cylinder and a lower working cylinder of the recovery valve system is further arranged corresponding to the recovery valve system. The lower end of the outer cylinder barrel and the lower end of the inner cylinder barrel are connected in a sealed mode through a compression valve system, and a compression adjusting mechanism used for adjusting the oil flow volume between the working cylinder and the oil storage cylinder is further arranged corresponding to the compression valve system. According to the double-adjustable-damping shock absorber, the matching performance of the compression damping after the recovery damping is adjusted can be accurately adjusted according to user requirements, and therefore it is ensured that the vehicle suspension performance is in the optimal state.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a double adjustable damping 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 be...
