[0061] As a preferred embodiment, Figure 3 and Figure 4As shown in , the mounting structure includes a support pad 8 and a plurality of connecting components 9. The leaf spring 5 is connected to the bottom of the lower wall 102 through the support pad 8 and the connecting components 9, and connecting components 9 are respectively provided on both sides of the leaf spring 5. Here, the mounting structure adopts the support pad 8 and the connecting components 9, which has a simple structure, is easy to manufacture, and helps to reduce costs.

[0062] In some embodiments, Figure 3 and Figure 4 As shown in the figure, a leaf spring mounting hole 1021 is provided on the lower wall 102, and a connecting through hole is provided on the support shoe 8.

The connection assembly 9 adopts a screw connection structure composed of a bolt 901 and a nut 902, which is easy to operate and can ensure the reliability of the installation of the leaf spring 5.

[0064] In some embodiments, as a structural example, Figure 4 As shown in , corresponding to the two sides in the width direction of the leaf spring 5, two leaf spring mounting holes 1021 are arranged in a front-to-back spacing on the lower wall 102, and the connecting through holes on the support pad 8 are arranged in a one-to-one correspondence with the leaf spring mounting holes 1021. At this time, four bolts 901 and four nuts 902 are required. Of course, the number of leaf spring mounting holes 1021 in this embodiment can also be adaptively adjusted as long as the connection requirements are met.

[0065] During the specific connection, each bolt 901 can pass through the leaf spring mounting hole 1021 and the corresponding connecting through hole from top to bottom, and be screwed and connected with the nut 902 located at the bottom of the support pad 8. At this time, the nut 902 can be set independently of the support pad 8, or it can be fixedly connected to the bottom of the support pad 8.

[0066] Of course, each bolt 901 can also pass through the connecting hole and the corresponding leaf spring mounting hole 1021 from bottom to top, and be screwed to the nut 902 located at the top of the lower wall 102.

[0069] As a preferred embodiment, the upper surface of the upper wall 101 forms a limited surface 1011, and the limited surface 1011 is used to abut against the buffer block 3 on the frame under the excitation of wheel hop. Forming the limited surface 1011 on the upper surface of the upper wall 101 helps to achieve the buffering and limiting function between the integral bridge and the frame, which is beneficial to improving the driving comfort of the vehicle.

[0070] Here, the installation and structural form of the buffer block 3 on the frame can refer to the prior art. Figure 1 In the structure shown in , the buffer block 3 can be connected to the base 301 by vulcanization or bonding, and is connected to the frame through the base 301. And the buffer block 3 is made of a rubber material with suitable elasticity and good weather resistance and durability.

[0071] The steering knuckle 100 in this embodiment is integrally cast. This facilitates the preparation of the steering knuckle 100, reduces the cost of the steering knuckle 100, and ensures the structural strength of the steering knuckle 100. In addition, a weight-reducing structure not shown in the figure may be provided on at least one of the upper wall 101 and the lower wall 102 to achieve a lightweight design of the steering knuckle 100. The weight-reducing structure here may be at least one of a weight-reducing groove and a weight-reducing hole.
