Embodiment Construction

[0050] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments. .

[0051] First of all, it is explained that the technical concept of the shock absorber of the present invention can be generally applied to the structural improvement of existing shock absorbers. Any shock absorber that adopts the basic technical concept of the present invention belongs to the protection scope of the present invention. As mentioned above, the shock absorber is a commonly used component in the vehicle suspension system. It is generally a double-acting shock absorber. The vibration reduction principle of this kind of shock absorber is basically the same. Also basically similar. In order to h...

Abstract

Provided is a shock absorber, comprising an oil storage cylinder (13), a working cylinder (14), a piston rod (6), a guiding and sealing assembly used to guide the movement of the piston rod (6), and an expansion and circulation valve assembly and a compression and compensation valve assembly provided on a piston (16). The guiding and sealing assembly comprises a guide seat (27, 29) and an oil seal (34) located at the upper end of the guide seat. The face of the upper end of the guide seat (27, 29) is formed with an oil storage groove, and the oil storage groove has an oil-air separation contact surface (35). An elastic separation lip (36) is formed on the oil seal (34) and the elastic separation lip (36) is in airtight contact with the oil-air separation contact surface (35) such that the oil storage groove is separated into an outside part and an inside part. Moreover, further provided are a vehicle suspension system and a vehicle comprising the shock absorber. The piston rod of the shock absorber has good movement stability, the friction between the piston and the inner wall of the working cylinder is low, and the shock absorber has a long service life and has significantly improved dampening effects.

Description

technical field [0001] The present invention relates to a component of a vehicle suspension system, in particular to a shock absorber. Furthermore, the present invention also relates to a vehicle suspension system comprising the shock absorber and a vehicle. Background technique [0002] As we all know, the shock absorber in the vehicle suspension system is supported between the vehicle frame and the axle to speed up the damping of vibration and limit the vibration of the vehicle body and wheels during the running of the vehicle. The main function of the shock absorber is to absorb the vibration of the vehicle when the elastic components (such as leaf springs) of the vehicle suspension system rise and fall, so that the vehicle can quickly return to a stable state and improve the driving stability of the vehicle. [0003] The shock absorber used in the vehicle suspension system is generally a hydraulic shock absorber, and its main principle is to use liquid resistance to dis...
