Further, both ends of the connecting plate 22 are welded to the lower shock absorbing pipes of the main shock absorber 5 at both sides, respectively.

The beneficial effect of adopting the further technical scheme is that: the possibility and the degree of bending deformation of the main shock absorber 5 under stress are reduced; the rotation of the lower tube of the main suspension 5, that is, the rotation of the sub suspension 6 is prevented.

Preferably. The telescopic track of the auxiliary shock absorber 6 when stressed is a straight line, the telescopic track of the main shock absorber 5 when stressed is a straight line, the included angle between the two straight lines is an acute angle, and the angle is preferably 80-85 degrees.

Preferably. The main damper 5 is an elastic damper, such as a spring damper; it can also be a hydraulic shock absorber; or other types of shock absorbers.

Preferably. The auxiliary shock absorber 6 is an elastic shock absorber or a hydraulic shock absorber.

Preferably. When the auxiliary shock absorber 6 is a hydraulic shock absorber, the shock absorbing effect is good.
