The elastic member 112 is slidably sleeved on the rod body of the limiting rod 113, and the elastic member 112 is a spring.

[0028] When specifically arranged, there are two sets of limit members 110, and the two sets of limit members 110 are symmetrically arranged. The fixed sleeves 111 inside the two sets of limit members 110 are both fixedly connected to the lower surface of the suspension main body 100.

[0029] Please refer to Figures 1-4 , a bottom plate 201 is provided on the bottom surface of the vehicle body height sensor 200, a buffer pad 101 is provided on the upper surface of the suspension main body 100, the bottom plate 201 abuts against the buffer pad 101.
