Description

Shock absorber, suspension system and vehicle

Technical Field

The utility model relates to the technical field of suspension structures of automobiles, in particular to a shock absorber, a suspension system and a vehicle.

Background

In order to quickly attenuate the vibration of the frame and the vehicle body and improve the smoothness and comfort of the running of the vehicle, a shock absorber is generally arranged on a suspension system of the vehicle. The shock absorbers widely used at present are mainly double-cylinder hydraulic shock absorbers, and the double-cylinder shock absorbers are divided into strut type double-cylinder shock absorbers and general double-cylinder shock absorbers.

Compared with a common double-cylinder shock absorber, the strut type double-cylinder shock absorber is characterized in that a spring tray and various brackets connected with other suspensions are added on an outer cylinder assembly. The spring tray is used for supporting the springs, and the height of the positions of the springs determines the height of the springs and further determines the height of the vehicle; and the structure of the spring tray directly influences the design of the spring, and further influences the lateral stress of the shock absorber. Considering that the height and the eccentric point of the spring are determined by the position of the spring tray on the cylinder barrel and the structure of the tray, the installation position and the installation structure of the spring tray are key points of the whole shock absorber, if the position design of the spring tray is unreasonable, the specific parameter design of the spring can be influenced, and the performance of the whole shock absorber can be further influenced.

The spring tray in the prior art is usually welded directly to the cylinder barrel of the shock absorber, and the position of the spring tray is correspondingly fixed after the welding is finished, so that the height of the spring and the size of the tray cannot be adjusted; and the welding process may affect the dimensional accuracy of the cylinder.

In addition, in the prior art, the height of the air spring can be adjusted by changing the inflation pressure inside the air spring, but the system adopting the air spring has the following disadvantages: the tray of the air spring still needs to be welded with the cylinder; the air spring is sensitive to lateral force, and the design requirement of the air spring on eccentricity cannot be met; the air spring has long development period and high cost.
