Problems solved by technology

[0003] However, the stroke of the existing shock absorber, that is, the movable range of the piston and the piston rod, is limited by the length of the cylinder. The larger the cylinder length, the longer the stroke, and the smaller the cylinder length, the shorter the stroke.
Therefore, on the premise of satisfying the stroke requirements, the length of the cylinder body of the existing shock absorber is relatively large, resulting in large weight and large accommodation space, which is not conducive to installation

Abstract

The invention provides a shock absorber and relates to the technical field of shock absorption. The shock absorber comprises a cylinder barrel, a piston shaft, a piston and a floating plug; the cylinder barrel is provided with an oil cavity containing hydraulic oil; the piston shaft is arranged at one end of the cylinder barrel in sliding and penetrating modes, the piston shaft is of a hollow structure with a sealed end and an open end, and the open end is located in the oil cavity; the piston is arranged in the oil cavity and is in sealed fit with the side wall of the oil cavity in a slidingmode so as to divide the oil cavity into a first cavity body and a second cavity body; the piston is connected with the piston shaft and exposed out of the open end, the piston is provided with a damping channel, and when the piston moves back and forth, the hydraulic oil can flow in the first cavity and the second cavity through the damping channel; and the floating plug is arranged in the pistonshaft and is in sealed fit with the inner wall of the piston shaft in a sliding mode so that an air cavity can be formed between the floating plug and the sealed end, and compressed air is containedin the air cavity.

Description

technical field [0001] The present disclosure relates to the technical field of shock absorption, and in particular, to a shock absorber. Background technique [0002] At present, the suspension system of a car is generally equipped with a shock absorber to attenuate the vibration during the running of the car to ensure smooth driving. Among them, hydraulic shock absorbers are widely used. The existing hydraulic shock absorber includes a cylinder, a piston, a floating ring, a piston rod, etc. The piston and the floating ring can be installed in the cylinder along the axial direction, and the floating ring can divide the cylinder into an oil chamber and an air chamber. There is hydraulic oil in the oil chamber and gas in the air chamber; the piston has a valve hole and can move back and forth in the cylinder body. With the movement of the piston, the hydraulic oil can flow through the valve hole, and the pressure of the hydraulic oil can be controlled by the valve hole. The...
