[0046] "Multiple" appearing in the application means more than two (including two), and similarly, "multiple groups" means more than two groups (including two groups), and "multiple pieces" means more than two pieces (including two pieces).

[0047] It should be noted that, with the rapid development of new energy vehicles, the weight of the whole vehicle is getting larger and the chassis layout space is getting smaller, so higher performance requirements are put forward for independent suspensions, among which the hub bracket as an important part of the independent suspension mainly functions to transmit the excitation input to the tire by the road to the vehicle body, so the hub bracket needs to be able to withstand greater impact and load. However, the traditional hub bracket is usually manufactured by casting or forging process, and the load bearing capacity and impact resistance of the hub bracket are poor, which is difficult to meet the load bearing demand of new energy vehicles.

[0048] Based on this, the application provides a hub bracket 100, along the thickness direction of the mounting seat 1, the shock absorber mounting bracket 2 and the brake mounting bracket 3 are respectively installed on the first side 11 and the second side 12 of the mounting seat 1, and at least part of the projection of the first connecting area of the shock absorber mounting bracket 2 and at least part of the projection of the second connecting area of the brake mounting bracket 3 are overlapped, thereby realizing the partial connecting area of the shock absorber mounting bracket 2, the mounting seat 1 and the brake mounting bracket 3 in the thickness direction of the mounting seat 1 is sequentially stacked, so as to realize the local thickening design of the hub bracket 100, which is conducive to improving the overall stiffness of the hub bracket 100, and further improving the load bearing capacity of the hub bracket 100, so that it can withstand greater load and impact force, so as to meet the load bearing demand of new energy vehicles. At the same time, the shock absorber mounting function and the brake mounting function are integrated into the hub bracket 100, so as to be conducive to improving the integration performance of the hub bracket 100, and also conducive to reducing the number of parts, and further conducive to reducing the assembly process and cost.

[0049] As shown in Figures 1-4 , the hub bracket 100 according to the first aspect of the application comprises: a mounting seat 1, a shock absorber mounting bracket 2 and a brake mounting bracket 3.

[0050] Among them, along the thickness direction of the mounting seat 1, the mounting seat 1 has the first side 11 and the second side 12 arranged oppositely, the shock absorber mounting bracket 2 is fixedly arranged on the first side 11 and forms a first connecting area, and the brake mounting bracket 3 is fixedly arranged on the second side 12 and forms a second connecting area, wherein along the thickness direction of the mounting seat 1, at least part of the projection of the first connecting area and at least part of the projection of the second connecting area are overlapped.

[0051] Specifically, referring to Figure 2 and Figure 3As shown, along the thickness direction of the mounting seat 1, the damper mounting bracket 2 and the brake mounting bracket 3 are fixedly mounted on both sides of the mounting seat 1 respectively, wherein the damper mounting bracket 2 is fixedly connected with the first side 11 of the mounting seat 1, and the brake mounting bracket 3 is fixedly connected with the second side 12 of the mounting seat 1, and the fixed connection mode includes but is not limited to welding. It can be understood that the damper mounting bracket 2 forms a first connection area after being fixedly connected with the mounting seat 1, and the brake mounting bracket 3 forms a second connection area after being fixedly connected with the mounting seat 1. For example, as shown in Figure 2 and Figure 3 If the damper mounting bracket 2 is welded with the mounting seat 1, the fitting area surrounded by the welding seam between the damper mounting bracket 2 and the mounting seat 1 is the first connection area. If the brake mounting bracket 3 is welded with the mounting seat 1, the fitting area surrounded by the welding seam between the brake mounting bracket 3 and the mounting seat 1 is the second connection area.

[0052] Further, along the thickness direction of the mounting seat 1, the projection of at least part of the first connection area and the projection of at least part of the second connection area overlap, that is, part of the connection area of the damper mounting bracket 2 and the mounting seat 1 and part of the connection area of the brake mounting bracket 3 and the mounting seat 1 overlap in the thickness direction of the mounting seat 1, so that the damper mounting bracket 2, the mounting seat 1 and the brake mounting bracket 3 are sequentially stacked in the partial connection area of the mounting seat 1 in the thickness direction, that is, the thickness of the three-layer stacked connection area of the damper mounting bracket 2, the mounting seat 1 and the brake mounting bracket 3 is relatively thick, and the local thickness of the hub bracket 100 is increased, which is beneficial to improve the anti-deformation ability of the hub bracket 100 under stress, thereby improving the overall stiffness of the hub bracket 100, and further improving the carrying capacity of the hub bracket 100, so that it can withstand greater load and impact force to meet the carrying demand of new energy vehicles.

[0053] It should be noted that by providing the damper mounting bracket 2 and the brake mounting bracket 3 on the hub bracket 100, the damper mounting function and the brake mounting function can be integrated into the hub bracket 100. Such a design is beneficial to improve the integration performance of the hub bracket 100, reduce the number of parts, and further reduce the assembly process and cost.

[0054] Further, since the brake mounting bracket 3 is independently designed relative to the hub bracket 100, it can be adjusted according to the needs of different vehicle models. By flexibly adjusting the specifications of the brake mounting bracket 3, different vehicle model requirements can be met, thereby facilitating the expansion of the hub bracket 100.

[0055] In some embodiments of the present application, the mounting seat 1 is different from the existing material selection and process. The mounting seat 1 can be made of stamping sheet metal process and cooperatively welded with the shock absorber mounting bracket 2 and the brake mounting bracket 3. Compared with the traditional casting aluminum, forging aluminum, cast iron or forging iron cooperative machining process, the hub bracket 100 structure is simpler and the cost is lower. At the same time, the sheet metal part has better toughness and can withstand greater load and impact of the vehicle body.

[0056] In summary, according to the hub bracket 100 provided by the first aspect of the present application, the shock absorber mounting bracket 2 and the brake mounting bracket 3 are respectively mounted on the first side 11 and the second side 12 of the mounting seat 1 along the thickness direction of the mounting seat 1, and the projection of at least part of the first connecting area of the shock absorber mounting bracket 2 overlaps with the projection of at least part of the second connecting area of the brake mounting bracket 3. Thus, the partial connecting areas of the shock absorber mounting bracket 2, the mounting seat 1 and the brake mounting bracket 3 are sequentially stacked in the thickness direction of the mounting seat 1, thereby realizing the local thickening design of the hub bracket 100, which is beneficial to improve the overall stiffness of the hub bracket 100, and further improve the carrying capacity of the hub bracket 100, so that it can withstand greater load and impact force, to meet the carrying demand of new energy vehicles. At the same time, the shock absorber mounting function and the brake mounting function are integrated into the hub bracket 100, which is beneficial to improve the integration performance of the hub bracket 100, and also beneficial to reduce the number of parts, and further beneficial to reduce the assembly process and cost.

[0057] In some embodiments of the present application, as shown in Figure 2 and Figure 4 along the first direction X, the first side 11 of the mounting seat 1 has the first flange 13 and the second flange 14 which are oppositely arranged and spaced apart. The first direction X is the length direction of the vehicle when the mounting seat 1 is installed on the vehicle, that is, when the mounting seat 1 is installed on the vehicle, the first direction X is consistent with the length direction of the vehicle. In this way, by arranging the first flange 13 and the second flange 14, it is beneficial to improve the anti-deformation ability of the mounting seat 1 after being stressed, thereby improving the rigidity of the mounting seat 1, and further improving the overall rigidity of the hub bracket 100.

[0058] Further, along the first direction X, that is, in the length direction of the vehicle, the shock absorber mounting bracket 2 has the third flange 21 and the fourth flange 22 which are oppositely arranged and spaced apart. In this way, by arranging the third flange 21 and the fourth flange 22, it is beneficial to improve the anti-deformation ability of the shock absorber mounting bracket 2 after being stressed, thereby improving the rigidity of the shock absorber mounting bracket 2, and further improving the overall rigidity of the hub bracket 100.

[0059] Further, the third flange 21 and the fourth flange 22 are both arranged between the first flange 13 and the second flange 14, the first flange 13 is closer to the third flange 21 than the second flange 14, the first flange 13 and the third flange 21 are oppositely arranged and spaced apart, and the first flange 13 and the third flange 21 jointly form the first trailing arm mounting portion 15, the second flange 14 is closer to the fourth flange 22 than the first flange 13, the second flange 14 and the fourth flange 22 are oppositely arranged and spaced apart, and the second flange 14 and the fourth flange 22 jointly form the second trailing arm mounting portion 16.

[0060] That is, as shown in Figure 2 the first direction X, the first flange 13, the third flange 21, the fourth flange 22, and the second flange 14 are sequentially and spaced apart, wherein the spacing region between the first flange 13 and the third flange 21 is the first trailing arm mounting space, and the first flange 13 and the third flange 21 both have oppositely arranged first trailing arm mounting holes. It can be understood that the two first trailing arm mounting holes are both the first trailing arm mounting portion 15. When the hub bracket 100 is assembled with the first trailing arm 200, one end of the first trailing arm 200 is arranged in the first trailing arm mounting space, and then the first trailing arm 200 is fixed with the two first trailing arm mounting holes through a bushing, while the other end of the first trailing arm 200 is connected with the subframe, so that the road excitation received by the hub bracket 100 can be transmitted to the subframe through the first trailing arm 200. Similarly, the spacing region between the fourth flange 22 and the second flange 14 is the second trailing arm mounting space, and the fourth flange 22 and the second flange 14 both have oppositely arranged second trailing arm mounting holes. It can be understood that the two second trailing arm mounting holes are both the second trailing arm mounting portion 16. When the hub bracket 100 is assembled with the second trailing arm 300, one end of the second trailing arm 300 is arranged in the second trailing arm mounting space, and then the second trailing arm 300 is fixed with the two second trailing arm mounting holes through a bushing, while the other end of the second trailing arm 300 is connected with the subframe, so that the road excitation received by the hub bracket 100 can be transmitted to the subframe through the second trailing arm 300. In this way, the function integration of the two trailing arm mounting points of the hub bracket 100 is realized, and the integration performance of the hub bracket 100 is further improved. At the same time, the use of flanges as trailing arm mounting portions not only realizes the reuse of components, but also is conducive to saving materials and costs, and the flange structure has strong rigidity and meets the support requirements.

[0061] In some embodiments of the present application, as shown in Figure 2 and Figure 4 the first side 11 of the mounting seat 1 has a mounting plate 17, which is oppositely arranged and spaced apart from the second flange 14 along the first direction X, and the mounting plate 17 and the second flange 14 jointly form a third trailing arm mounting portion 18.

[0062] Specifically, the spacing area between the mounting plate 17 and the second flange 14 is a third lateral arm mounting space, and the mounting plate 17 and the second flange 14 both have a third lateral arm mounting hole arranged opposite to each other. It can be understood that the two third lateral arm mounting holes are both third lateral arm mounting portions 18. When the hub support 100 is assembled with the third lateral arm 400, one end of the third lateral arm 400 is arranged in the third lateral arm mounting space, and then the third lateral arm 400 is fixed with the two third lateral arm mounting holes through a bushing, and the other end of the third lateral arm 400 is connected with the subframe, so that the road excitation received by the hub support 100 can be transmitted to the subframe through the third lateral arm 400. It should be noted that the third lateral arm mounting portion 18 is spaced apart from the second lateral arm mounting portion 16 to avoid interference between the second lateral arm 300 and the third lateral arm 400. In this way, the functional integration of the three lateral arm mounting points of the hub support 100 is realized, the integration performance of the hub support 100 is further improved, and the force transmission route of the hub support 100 is also increased. At the same time, the second flange 14 is used as a lateral arm mounting portion, which realizes the reuse of the second flange 14, is conducive to saving materials and costs, and the flange structure has high rigidity and meets the support requirement.

[0063] In some embodiments of the present application, as shown in Figure 3 The mounting seat 1 also has a mounting protrusion 19 corresponding to the third lateral arm mounting portion 18. That is, the mounting seat 1 also has a mounting protrusion 19 in the area corresponding to the third lateral arm mounting portion 18. It can be understood that the mounting protrusion 19 is arranged opposite to the third lateral arm mounting space. In this way, it is conducive to improving the volume of the third lateral arm mounting space, so as to provide sufficient space for the installation of the third lateral arm 400. At the same time, the mounting protrusion 19 is also conducive to improving the anti-deformation performance of the mounting seat 1, so as to improve the dynamic stiffness of the mounting seat 1, and further improve the overall dynamic stiffness of the hub support 100.

[0064] In some embodiments of the present application, as shown in Figure 2 and Figure 4 The third flange 21 and the fourth flange 22 jointly form a shock absorber mounting portion 23.

[0065] Specifically, a damping device mounting space is formed in the interval region between the third flange 21 and the fourth flange 22, and the third flange 21 and the fourth flange 22 each have a damping device mounting hole arranged opposite to each other. It can be understood that the two damping device mounting holes are each a damping device mounting portion 23. When the damping device 500 is assembled with the damping device mounting bracket, one end of the damping device 500 is arranged in the damping device mounting space, and then the damping device 500 is fixed with the two damping device mounting holes through a bushing, and the other end of the damping device 500 is connected with the auxiliary frame, so that the road excitation received by the hub bracket 100 can be transmitted to the auxiliary frame through the damping device 500, and damping is performed through the damping device 500. By arranging the third flange 21 and the fourth flange 22 as the damping device mounting portion 23, the third flange 21 and the fourth flange 22 are reused, which is beneficial to saving materials and costs, and the flange structure has high rigidity and meets the support requirement.

[0066] In some embodiments of the present application, as shown in Figure 2 and Figure 4 The third flange 21 includes a first segment 211, a first transition segment 212, and a second segment 213 connected with each other, and the fourth flange 22 includes a third segment 221, a second transition segment 222, and a fourth segment 223 connected with each other. For example, the third flange 21 and the fourth flange 22 are symmetrically arranged, and the third flange 21 and the fourth flange 22 can be configured in the same structure. The first segment 211 is arranged opposite to and spaced apart from the third segment 221, the first segment 211 forms the first control arm mounting portion 15, the third segment 221 forms the second control arm mounting portion 16, the second segment 213 is arranged opposite to and spaced apart from the fourth segment 223, the second segment 213 and the fourth segment 223 jointly form the damping device mounting portion 23, and along the first direction X, the interval distance between the first segment 211 and the third segment 221 is greater than the interval distance between the second segment 213 and the fourth segment 223. That is, along the first direction X, the second segment 213 and the fourth segment 223 are located between the first segment 211 and the third segment 221. Since the damping device mounting space formed between the second segment 213 and the fourth segment 223 is small, the anti-deformation capability of the damping device mounting portion 23 is improved, so that the damping device mounting bracket 2 is suitable for larger load impact of the damping device 500. Meanwhile, the third flange 21 and the fourth flange 22 form a variable cross-section structure, which is beneficial to further improving the dynamic stiffness and stability of the damping device mounting bracket 2.

[0067] In some embodiments of the present application, as shown in Figure 2 and Figure 4 The longitudinal arm mounting bracket 4 is fixedly arranged on the first side 11 of the mounting seat 1, and at least part of the longitudinal arm mounting portion 41 of the longitudinal arm mounting bracket 4 protrudes out of the mounting seat 1.

[0068] Specifically, the hub bracket 100 is further integrated with a longitudinal arm 600 mounting point. The longitudinal arm mounting bracket 4 is fixedly installed on the first side 11 of the mounting seat 1 in a manner including but not limited to welding, bolt connection, etc. Further, at least part of the longitudinal arm mounting portion 41 of the longitudinal arm mounting bracket 4 protrudes from the mounting seat 1.
