Abstract

The invention relates to a bidirectional adjustable shock absorber which comprises a liquid storage cylinder assembly, a compression valve assembly and an oil sealing guide device assembly. The liquid storage cylinder assembly is internally provided with a piston rod assembly capable of moving axially. The bottom of the piston rod assembly is fixedly provided with a recover valve assembly. The piston rod assembly comprises a hollow piston rod body, an interlocking nut, a positioning sleeve assembly, an ejector rod and an ejector rod adjuster assembly. The hollow piston rod body is provided with an overflowing hole. The overflowing hole is communicated with an inner cavity of the liquid storage cylinder assembly through the interlocking nut. By means of the bidirectional adjustable shock absorber, the damping of the shock absorber can be adjusted according to different use road conditions, the manipulation of an automobile can be improved accordingly, and manipulation is made to be more comfortable. The bidirectional adjustable shock absorber is stable in damping force, high in production efficiency and good in stability.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to a two-way adjustable shock absorber. Background technique [0002] When the shock absorber is running, the piston rod of the shock absorber moves up and down, driving the oil to generate damping force through the piston valve and compression valve, absorbing the vibration energy of the vehicle, and playing the effect of shock absorption and buffering, ensuring the ride comfort. At present, the structure of the existing shock absorber generally includes an oil storage cylinder, a working cylinder arranged in the oil storage cylinder, a compression valve arranged at the bottom of the working cylinder, a piston which moves up and down is arranged in the working cylinder, and a piston valve is arranged on the piston rod. , the piston valve divides the working cylinder into upper and lower chambers. The damping of this kind of shock absorber cannot be adjusted, an...
