[0046] In some embodiments, Figure 4 As shown in , a drainage groove 1033 is provided at the bottom of the inner wall of the hub bearing mounting hole 1031. The drainage groove 1033 is connected to the hub bearing mounting hole 1031 and the outside of the side wall 103 to facilitate the discharge of water entering the hub bearing 6 position, which helps to improve the service life of the hub bearing 6.

[0047] As a preferred embodiment, an outwardly protruding mounting ear 1034 is provided at the edge of the side wall 103, and the brake caliper mounting portion is provided on the mounting ear 1034. The mounting ear 1034 is provided on the side wall 103, so that the brake caliper mounting portion is located on the mounting ear 1034, which can facilitate the installation of the brake caliper mounting portion on the steering knuckle, and also helps to avoid a significant increase in the weight of the steering knuckle, which is conducive to ensuring the lightweight of the steering knuckle.

[0048] like Figure 3 and Figure 4 As shown in , the mounting ears 1034 are multiple and arranged at intervals, and the brake caliper mounting portion includes a brake caliper mounting hole 1035 provided on the mounting ears 1034. The mounting ears 1034 are multiple, which can ensure the reliability of the brake caliper installation. The brake caliper mounting portion adopts the brake caliper mounting hole 1035, which has a simple structure and is conducive to the installation operation of the brake caliper. Further, the mounting ears 1034 are located at the rear edge of the side wall 103, and the curved tube beam connecting portion 2 is connected between the upper wall 101 and the rear side of the lower wall 102. In this way, the arrangement space formed on both sides of the axle of the curved tube beam 4 can be fully utilized, which is helpful to realize the installation arrangement of the brake caliper and is conducive to avoiding interference between the brake caliper and surrounding parts.

[0049] For example, two mounting ears 1034 are spaced apart in the height direction of the side wall 103, and the brake caliper mounting holes 1035 on the two mounting ears 1034 cooperate to improve the installation effect of the brake caliper. The brake caliper mounting hole 1035 may also be a threaded hole, and in addition to the brake caliper mounting hole 1035, the brake caliper mounting portion may also be other conventional mounting structures provided on the mounting ears 1034.

[0050] In this embodiment, the width of the mounting ears 1034 is reduced in the direction away from the side wall 103, which is conducive to improving the structural strength of the connection between the mounting ears 1034 and the side wall 103. Of course, in specific implementation, the number of mounting ears 1034 can also be adaptively adjusted according to needs.

[0051] like Figure 1 and Figure 3 and Figure 4 As shown in , the bent tube beam connection part 2 includes a connection body 201, and a connection arm 202 connecting the connection body 201 between the upper wall 101 and the lower wall 102, and the connection body 201 is provided with a connection hole 2011 for inserting the end of the bent tube beam 4. In this embodiment, the bent tube beam connection part 2 is composed of the connection body 201 and the connection arm 202, and has a simple structure and is easy to design and shape. The connection hole 2011 for inserting the end of the bent tube beam 4 is provided on the connection body 201, which can facilitate the connection with the bent tube beam 4 and also ensure the stability of the connection with the bent tube beam 4.

[0052] In terms of specific structure, the bent tube beam connection part 2 corresponds to the inner side of the steering knuckle body 1, and is connected between the upper wall 101 and the rear side of the lower wall 102. The connection body 201 is columnar, and the connection hole 2011 is extended from one end of the connection body 201 facing the inside of the vehicle to the other end. After the end of the bent tube beam 4 is inserted into the connection hole 2011, the bent tube beam 4 and the connection body 201 are usually fixed together by welding.

[0053] In addition, the top of the connecting body 201 is connected to the rear side of the upper wall 101 through the connecting arm 202, and the bottom of the connecting body 201 is connected to the rear side of the lower wall 102 through the connecting arm 202. The thickness of each connecting arm 202 is gradually reduced in the direction away from the connecting body 201, which is conducive to improving the connection strength between the connecting arm 202 and the connecting body 201, thereby improving the use stability of the bent tube beam connecting part 2.

[0054] As a preferred embodiment, the leaf spring mounting portion includes a leaf spring mounting hole 1021 provided on the lower wall 102. Here, the leaf spring mounting hole 1021 has a simple structure, is easy to form, and is also convenient for the installation operation of the leaf spring 5. Figures 2 to 4As shown in , there are four leaf spring mounting holes 1021 arranged at intervals along the front-to-back direction and the left-to-right direction. Among them, the two leaf spring mounting holes 1021 arranged along the left-to-right direction of the vehicle can be passed through by the U-shaped connector to connect with the leaf spring 5 arranged at the bottom of the lower wall 102, thereby fixing the leaf spring 5 on the lower wall 102.

[0055] Of course, in addition to being connected by the U-shaped connector, the leaf spring 5 can also be fixed to the lower wall 102 by a connector such as a bolt passing through the leaf spring mounting hole 1021, mainly to meet the installation requirements of the leaf spring 5. In addition, the number of the leaf spring mounting holes 1021 can also be determined according to the use requirements.

[0056] In addition, the lower wall 102 is provided with a positioning hole 1022 for positioning the leaf spring 5. Figure 3 As shown in , the positioning hole 1022 can be located in the middle of the plurality of leaf spring mounting holes 1021 for the positioning column at the top of the leaf spring 5 to be inserted, which is beneficial for positioning the leaf spring 5 on the lower wall 102, thereby improving the installation efficiency of the leaf spring 5.

[0057] As a preferred embodiment, the upper surface of the upper wall 101 forms a limited surface, which is used to abut against the buffer block 3 on the frame under wheel hop excitation. Forming the limited surface on the upper surface of the upper wall 101 helps to achieve the buffering and limiting function between the axle of the bent tube beam 4 and the frame, which is beneficial to improving the driving comfort of the vehicle.

[0058] Here, the installation and structural form of the buffer block 3 on the frame can refer to the prior art. Figure 1 As 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. The buffer block 3 can be made of a rubber material with suitable elasticity and good weather resistance and durability.

[0059] In specific implementation, the steering knuckle body 100 in this embodiment is integrally cast. This can facilitate the preparation of the steering knuckle, reduce the cost of the steering knuckle, and also ensure the structural strength of the steering knuckle. In addition, a weight reduction structure not shown in the figure is provided on at least one of the upper wall 101 and the lower wall 102, so as to further reduce the weight of the steering knuckle, which is conducive to the lightweight design of the steering knuckle. The weight reduction structure here can be at least one of a weight reduction groove and a weight reduction hole. The weight reduction groove and the weight reduction hole have a simple structure, are easy to process and form, and are conducive to achieving the effect of weight reduction.

[0060] The steering knuckle in this embodiment, by optimizing its own structure, is conducive to the integrated arrangement of the wheel hub bearing 6, the brake caliper, the leaf spring 5, and the bent tube beam 4, and is conducive to reducing the space occupied by the steering knuckle and can reduce the weight of the entire vehicle, thereby improving the fuel economy of the entire vehicle.

[0061] When assembling the steering knuckle in this embodiment, the wheel hub bearing 6, brake caliper, leaf spring 5, and bent tube beam 4 can be installed in sequence. Among them, the wheel hub bearing 6 can be installed on the steering knuckle as a separate assembly, which is convenient for later maintenance and replacement.
