Definitions
- This application aims to solve one of the technical problems in the related art at least to a certain extent.
- the shock absorber assembly further includes a cover body, and the buffer body is adapted to be connected to the vehicle body through the cover body.
- a support is provided on the cylinder, and the spring abuts between the buffer body and the support.
- the height of the vehicle body can be adjusted, and the operating stability of the vehicle can be improved without compromising the comfort of the vehicle, effectively solving the contradiction between the comfort of the vehicle and the handling stability.
- the use of a hollow piston rod can not only reduce the weight, but also use the oil channel defined by the hollow piston rod to realize the discharge of oil to adjust the position of the piston rod.
- the adjustment method is simple, high reliability, low cost, and fast response. quick. It can also make the connection of the oil circuit stable, avoid the wear and tear of the connection due to vibration, and avoid the phenomenon of liquid leakage at the connection as much as possible.
- the shock absorber assembly 2 further includes an adapter 208 that communicates with the upper end of the oil passage 204 and is used to communicate with the outside world. Therefore, by setting the adapter 208, it is convenient to connect the shock absorber assembly 2 with the outside world.
- a support member 209 is provided on the cylinder body 201 , and the spring 205 abuts between the buffer body 206 and the support member 209 . Therefore, the spring 205 is supported by the supporting member 209 , which facilitates the assembly of the spring 205 .
- the support member 209 can cover the outer peripheral wall of the cylinder body 201 , and the support member 209 and the cylinder body 201 can be connected by interference fit or welding to ensure the reliable fixing of the support member 209 .
- the first connection port of the left rear shock absorber assembly communicates with the second connection port of the right rear shock absorber assembly to realize the connection between the upper chamber of the left rear shock absorber assembly and the right rear shock absorber assembly.
- the formed lower chamber is connected; the second connection port of the left rear shock absorber assembly is connected with the first connection port of the right rear shock absorber assembly, so as to realize the connection between the lower chamber of the left rear shock absorber assembly and the right rear
- the upper chamber of the shock absorber assembly communicates. In this way, the communication between the left and right side shock absorbers is realized, and then the anti-rolling function is realized.
- the vehicle according to the embodiment of the present application includes the shock absorber assembly 2 according to any one of the above-mentioned embodiments of the present application.
