The invention discloses a stroke sensitive damping adjustable shock absorber, which consists of a telescopic shock absorber and a parallel bypass valve. The parallel bypass valve comprises a tensile check valve fixing bolt, a tensile check valve block, a bypass floating piston, a floating piston ring, a compression check valve block, a compression bypass valve train and a tensile bypass valve train, wherein the tensile check valve block is arranged on the hole of the tensile check valve fixing bolt through the tensile check valve fixing bolt; the compression check valve block is arranged on the hole of the compression check valve fixing bolt through the compression check valve fixing bolt; the compression bypass valve train is connected with a compression bypass valve hole in the bypass valve body; the tensile bypass valve train is connected with the tensile bypass valve hole in the bypass valve body; the bypass valve floating piston is arranged in the bypass valve piston cavity between the compression bypass valve train and the tensile bypass valve train in a sliding connection way; and the floating piston ring is arranged in a fixed groove of the floating piston ring of the bypass valve floating piston. The parallel bypass valve is fixedly connected with the lower end of the telescopic shock absorber.
Description
technical field [0001] The invention relates to an adjustable damping mechanical shock absorber used in automobiles, more specifically, the invention relates to a stroke-sensitive adjustable damping shock absorber sensitive to stroke applied to automobile suspension. Background technique [0002] The suspension system of the vehicle is responsible for alleviating the impact of the road surface and attenuating the vibration of the vehicle body. The suspension is generally composed of guiding mechanisms, elastic elements, shock absorbers and other parts. Among them, the shock absorber is responsible for consuming vibration energy and attenuating the vibration amplitude. For mechanical shock absorbers, when the vehicle encounters an uneven road surface, the suspension moves up and down, the piston of the shock absorber reciprocates in the piston cylinder, and the liquid in each chamber flows through the valve system and the valve system in the shock absorber. Normally through ...
