[0021] In the present invention, a first connecting member 1, a second connecting member 2, a wheel hub assembly 3, at least one first shock absorber 4 and a second shock absorber 5 are provided. The first shock absorber 4 is connected to the vehicle body and the second connecting member 2 and performs shock absorption; the second shock absorber 5 is connected to the first connecting member 1 and the second connecting member 2 and performs shock absorption; the first shock absorber 4 and the second shock absorber 5 cooperate with each other, and compared with the existing technology, the shock absorption limit is greatly improved to meet the shock absorption needs during driving.

[0022] Specifically, the first connecting member 1 includes a first connecting frame 11 and a first fixing plate 12. One side of the first fixing plate 12 forms a fixing surface fixed to the vehicle body. The first fixing plate 12 is provided with a hinge seat. The first connecting frame 11 is hinged to the hinge seat, and the wheel hub assembly 3 is hinged to the first connecting frame 11.

[0023] Specifically, the second connecting member 2 includes a second connecting frame 21 and an adjustable fixing head 22. The adjustable fixing head 22 is fixed to the vehicle body and has an adjustable end. The adjustable end is hinged to the second connecting frame 21, which is hinged to the wheel hub assembly 3. The adjustable end is used to adjust the horizontal positional relationship between the second connecting frame 21 and the vehicle body. During use, the adjustable end can be adjusted to adjust the horizontal positional relationship between the second connecting frame 21 and the vehicle body, so that the wheel hub assembly 3 can remain perpendicular to the horizontal plane and prevent the wheel hub assembly 3 from tilting.

[0024] Furthermore, the adjustable fixed head 22 includes a U-shaped seat 221, an articulated rod 222, and an adjustment member 223. The U-shaped seat 221 is concave in the middle to form a U-shaped space. The U-shaped seat 221 is provided with a pair of oppositely disposed waist-shaped grooves 224. The articulated rod 222 is inserted through the waist-shaped grooves 224 and the U-shaped space, and has space for translation relative to the waist-shaped grooves 224.

The second shock absorbing carrier plate 52 is fixed to the vehicle body.

[0030] Furthermore, to avoid interference with the spring 51 , one end of the first connecting frame 11 fixed to the first fixing plate 12 extends to form two gradually diverging fixing branches 111 , and a space is formed between the two fixing branches 111 to avoid the spring 51 .

[0031] Furthermore, the spring 51 can be any one of a coil spring and an air spring.

[0032] Furthermore, when the spring 51 is a coil spring, in order to prevent the spring 51 from being skewed, a protrusion 211 is extended from the second connecting frame 21 and extends into the spring 51. The protrusion 211 can guide the extension and contraction direction of the spring 51 to prevent the spring 51 from being skewed.
