Description

Technical Field

[0001] This utility model relates to the field of wheel bracket technology, and in particular to a wheel bracket for automobiles. Background Technology

[0002] Automotive wheel brackets are key chassis components connecting the wheels to the vehicle body, primarily consisting of a load-bearing structure, steering mechanism, and suspension system. They secure the wheels to the vehicle body via rigid crossbeams and connecting brackets, while integrating steering functionality to allow the wheels to turn left and right, and working with the suspension system to absorb road impacts. This bracket system must withstand the vehicle's weight and dynamic loads during driving, while ensuring steering agility and driving stability. Its structural design directly affects the vehicle's handling, comfort, and safety, making it a core component of modern automotive chassis systems. However, existing automotive wheel brackets still suffer from poor overall load-bearing capacity and operational stability.

[0003] Therefore, it is essential to invent a wheel bracket for automobiles. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a car wheel bracket to solve the issues of poor overall load-bearing capacity and poor operational stability that still exist in existing car wheel brackets. A car wheel bracket includes a support beam, a steering bracket, a braking system, a wheel connecting seat, a body connecting bracket, and a steering drive structure. The steering bracket is installed at both ends of the support beam, and the braking system is installed on the outside of the steering bracket. The wheel connecting seat is also installed on the outside of the braking system. The body connecting bracket is fixedly installed above both ends of the support beam, and the steering drive structure is installed between the two sets of steering brackets.

[0005] The steering bracket includes a support base plate, a steering rotary seat, a main beam connecting bracket, a rotation drive rotary seat, and a steering power bracket. The main beam connecting bracket is fixedly installed at both ends of the support beam. The support base plate is rotatably installed on the outside of the main beam connecting bracket via the steering rotary seat. The rotation drive rotary seat is fixedly installed on the outside of the support base plate, and the steering power bracket is rotatably installed at the lower end of the rotation drive rotary seat and fixedly installed at both ends of the steering drive structure.

[0006] The vehicle body connecting bracket includes a load-bearing base, a vehicle connecting seat, a suspension bracket, a suspension arm, and a suspension rotating seat. The load-bearing base is fixedly installed above both ends of the support crossbeam and is connected and fixed to the vehicle frame through the vehicle connecting seat. The suspension bracket is fixedly installed on the outside of the load-bearing base, and the suspension arm is rotatably hinged inside the suspension bracket. The suspension rotating seat is fixedly installed on one end of the suspension arm.

[0007] The steering bracket as a whole can rotate at both ends of the support beam by being supported by the steering rotary seat, and the steering power bracket can move by being pushed by the steering drive structure. The movement of the steering power bracket can drive the support base plate to rotate by rotating the rotary seat. The rotary drive seat and the steering power bracket are a pair and are driven by two sets of steering drive structures.

[0008] The vehicle body connecting bracket elastically connects the support beam and the vehicle frame through the load-bearing base and the suspension structure; the suspension arms are in two sets, parallel to each other, and are rotatably connected to the vehicle frame, enabling the entire device to move relative to the vehicle body.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The steering bracket of this utility model is configured to fix the braking system and wheel connecting seat through the support base plate, and is rigidly connected to the support beam through the main beam connecting bracket; its steering rotating seat provides a rotation fulcrum, so that when the steering drive structure pushes the steering power bracket, the support base plate can achieve precise wheel steering by rotating the drive rotating seat. At the same time, it works in coordination with the suspension system of the body connecting bracket to ensure stable wheel load-bearing and steering flexibility. Finally, the synchronous control of the dual steering drive structure improves the overall vehicle handling stability.

[0011] The vehicle body connecting bracket of this utility model rigidly connects the support beam to the vehicle body through the force-bearing base and the vehicle connecting seat. At the same time, it forms a four-link suspension system with the help of the suspension bracket, the parallel-arranged suspension arms and the suspension rotating seat. This system can effectively transfer the wheel load to the vehicle body, allow the wheel to move vertically and limit the lateral displacement. It works in conjunction with the steering bracket to ensure that the suspension and steering system do not interfere with each other when steering, and buffers the impact of the road surface through the elastic element, thereby improving the ride comfort and handling stability while maintaining the tire positioning accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] As attached Figure 1 To be continued Figure 3 As shown.

[0019] This utility model provides a car wheel bracket, including a support beam 1, a steering bracket 2, a braking system 3, a wheel connecting seat 4, a body connecting bracket 5, and a steering drive structure 6, wherein: the steering bracket 2 is installed at both ends of the support beam 1, and the braking system 3 is installed on the outside of the steering bracket 2, and the wheel connecting seat 4 is installed on the outside of the braking system 3; the body connecting bracket 5 is fixedly installed above both ends of the support beam 1, and the steering drive structure 6 is installed between the two sets of steering brackets 2.

[0020] The steering bracket 2 includes a support base plate 21, a steering rotary seat 22, a main beam connecting bracket 23, a rotation drive rotary seat 24, and a steering power bracket 25. The main beam connecting bracket 23 is fixedly installed at both ends of the support beam 1. The support base plate 21 is rotatably installed on the outside of the main beam connecting bracket 23 via the steering rotary seat 22. The rotation drive rotary seat 24 is fixedly installed on the outside of the support base plate 21, and the steering power bracket 25 is rotatably installed at the lower end of the rotation drive rotary seat 24 and fixedly installed at both ends of the steering drive structure 6.

[0021] The vehicle body connecting bracket 5 includes a load-bearing base 51, a vehicle connecting seat 52, a suspension bracket 53, a suspension arm 54, and a suspension swivel seat 55. The load-bearing base 51 is fixedly installed above both ends of the support beam 1 and is connected and fixed to the vehicle frame through the vehicle connecting seat 52. The suspension bracket 53 is fixedly installed on the outside of the load-bearing base 51, and the suspension arm 54 is rotatably hinged inside the suspension bracket 53. The suspension swivel seat 55 is fixedly installed on one end of the suspension arm 54.

[0022] The steering bracket 2 can rotate at both ends of the support beam 1 by being supported by the steering rotating seat 22, and the steering power bracket 25 can move by being pushed by the steering drive structure 6. The movement of the steering power bracket 25 can drive the support base plate 21 to rotate by the rotation drive rotating seat 24. The rotation drive rotating seat 24 and the steering power bracket 25 are a pair and are driven by two sets of steering drive structures 6.

[0023] The vehicle body connecting bracket 5 is connected to the suspension structure via the load-bearing base 51, which enables the vehicle connecting seat 52 to elastically connect the supporting beam 1 and the vehicle frame; the suspension arm 54 is in two sets and parallel to each other, and the suspension arm 54 is rotatably connected to the vehicle frame, which enables the entire device to move relative to the vehicle body.

[0024] This automotive wheel support system achieves multifunctional integration through a structured mechanical transmission path. Body load is transferred to the support beam 1 via the body connecting bracket 5, and then distributed to the wheels by the steering bracket 2. During steering, the steering drive structure 6 pushes the steering power bracket 25, which in turn drives the rotating drive seat 24 to rotate the support base plate 21 around the steering rotating seat 22, achieving precise steering control. Simultaneously, the four-bar linkage formed by the parallel-arranged suspension arms 54 and the suspension rotating seat 55 ensures driving stability while maintaining the vertical freedom of wheel movement. All subsystems form an organic whole under the coordination of the support beam 1.

[0025] The system's innovation lies in its modular design, which decouples functions, allowing the steering, suspension, and braking systems to work independently yet collaboratively. The rotational motion of the steering bracket 2 is independent of the suspension oscillation of the body-connecting bracket 5, the dual steering drive structure 6 ensures steering synchronization, and the parallel layout of the suspension arms 54 precisely controls the wheel trajectory. This integrated design ensures structural strength while achieving a balance between handling precision, ride comfort, and braking stability, making it particularly suitable for the high-performance requirements of new energy vehicles' chassis systems.

[0026] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
