Problems solved by technology

The damping effect of the shock absorber will directly affect the driving stability of the car and the life of other parts. The commonly used two-way acting barrel shock absorber usually has a constant damping damping. The shock absorber is adaptive to different driving conditions. Poor performance, poor shock absorption

Embodiment Construction

[0020] figure 1 It is a structural schematic diagram of the present invention; figure 2 It is a schematic diagram of the local structure of the present invention;

[0021] As shown in the figure: this embodiment provides an automobile shock absorber, which includes a spool 1, an outer cylinder 2, a piston assembly and a shock absorbing main spring 3. The main spring 3 is placed on the column and is axially sliding and sealingly matched with the inner circle of the outer cylinder. The shock-absorbing main spring 3 is sleeved on the sliding column and the outer cylinder at the same time to provide elastic buffer force for the sliding column. The piston assembly includes a piston body, a sliding sleeve 4 and an elastic 5, the piston body is connected to the sliding column, the piston body has a damping channel 6 connected to the upper and lower chambers of the outer cylinder, and the bottom of the damping channel has several sets of lower passages arranged in the axial directio...

Abstract

The invention discloses an automobile shock absorber, which comprises a sliding column, an outer cylinder, a piston assembly and a shock absorbing main spring. The piston assembly includes a piston body, a sliding sleeve and an elastic member. The piston body is connected to the sliding column. There is a damping channel connected to the upper and lower chambers of the outer cylinder. The bottom of the damping channel has several sets of lower liquid holes arranged in the axial direction and connected to the lower chamber of the outer cylinder. The sliding sleeve can be slid up and down on the piston body. , the sliding sleeve is driven by the damping fluid in the lower chamber of the outer cylinder to move upward relative to the piston body and close the lower liquid passage holes one by one from bottom to top; the shock absorber of the present invention can adaptively change the shock absorption and damping according to the road conditions, and is more adaptable to road conditions Well, the damping force gradually increases during the shock absorption process, and the damping force changes more smoothly, which improves the shock absorption effect and ride comfort. The shock absorber can effectively prevent the piston assembly from bottoming out in relatively bumpy road conditions.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing and relates to an automobile shock absorber. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the car suspension system is equipped with a shock absorber, and the two-way acting barrel shock absorber is widely used in the car. The damping effect of the shock absorber will directly affect the driving stability of the car and the life of other parts. The commonly used two-way acting barrel shock absorber usually has a constant damping damping. The shock absorber is adaptive to different driving conditions. Poor performance, poor shock absorption effect. [0003] Therefore, based on the above problems, there is a need for an automobile shock absorber, which can adaptively change the shock absorption and damping based on road conditions, has better adaptability to road conditions, ...
