Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a support structure for a multi-spoke wheel hub. Background Technology

[0002] Automotive wheel hubs are key safety components in a vehicle's driving system. Their main functions are to mount tires, connect axles, and bear and transmit various loads generated during vehicle operation. With the development of the automotive industry, in order to meet consumers' dual demands for aesthetics and performance, multi-spoke wheel hub designs with multiple spokes have become the mainstream in the market.

[0003] In traditional multi-spoke wheel hub structures, multiple spokes typically extend independently radially to the outer rim, with the central disc as the base. Each spoke or group of spokes can be structurally considered as an independent support arm, primarily used to bear radial loads, effectively transferring the vehicle's vertical weight from the center to the rim.

[0004] However, when a vehicle makes high-speed turns, changes lanes suddenly, or travels on uneven surfaces, the wheel hub not only bears radial loads but also experiences complex lateral and shear forces. In such situations, due to the lack of effective lateral structural connections between the spokes, they must independently resist these complex stresses. This causes stress to concentrate on a few spokes, resulting in insufficient overall rigidity of the wheel hub structure, making it prone to minor deformations that can affect the vehicle's handling stability and ultimate performance. Existing multi-spoke wheel hubs generally lack effective structural support to coordinate the individual spokes in resisting complex stresses, which has become a technical bottleneck for improving the overall performance of the wheel hub.

[0005] Therefore, this utility model proposes a support structure for a multi-spoke wheel hub to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a support structure for a multi-spoke wheel hub, aiming to improve the problem in the prior art that the lack of effective lateral structural connections leads to insufficient overall rigidity and easy deformation of the wheel hub when subjected to lateral forces.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a support structure for a multi-spoke wheel hub, comprising the inner wheel hub; a central shaft coaxially disposed at the center of the inner wheel hub; a multi-spoke mechanism connected between the central shaft and the inner wheel hub, the multi-spoke mechanism comprising main spokes and secondary spokes extending from the ends of each main spoke away from the central shaft and connected to the inner wheel hub; and the support mechanism; The secondary spokes have mounting grooves on the side surface facing the vehicle body. Furthermore, the support mechanism includes the support ring, which is screwed and fixed in the mounting groove by the mounting bolts to connect the sub-spokes into a whole in the circumferential direction; Preferably, the outer surface of the main spoke is integrally formed with a spoke protrusion extending along its length direction; Preferably, the main spokes are further provided with recessed grooves; Preferably, a circular hole is formed on the ring wall of the support ring; Preferably, the multi-spoke mechanism is fixed to the central shaft by means of the fixing bolt passing through the root of the main spoke; Preferably, a mark is fixed at the end of the central shaft away from the inner hub; Preferably, the root of the main spoke connecting to the central shaft is formed as a wide base structure with a width greater than that of the middle section of the spoke; Preferably, a tire is mounted on the outer periphery of the inner hub.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the spokes of the wheel hub are independent and lack overall rigidity, making them prone to deformation when subjected to lateral forces. This is achieved by setting a support ring and fixing the support ring in the mounting groove opened on the side of multiple secondary spokes facing the vehicle body, so that the originally independent secondary spokes are connected in the circumferential direction into an integral structure. This improves the overall rigidity and shear resistance of the wheel hub and enhances the driving stability of the vehicle.

[0009] 2. This utility model solves the problem of insufficient connection points between the spokes and the rim in traditional wheel hubs and the tendency for stress concentration by setting a main spoke and a secondary spoke that branches off from the top of the main spoke and extends to the inner hub. It effectively distributes the load to multiple support points of the inner hub, reduces stress concentration, and improves the load-bearing capacity and impact resistance of the wheel hub.

[0010] 3. This utility model solves the problem of balancing strength and lightweight in traditional spoke structures by setting spoke protrusions that act as reinforcing ribs and recessed grooves that optimize the cross-section on the main spokes, thereby achieving the goal of effectively enhancing the strength of the main spoke structure while reducing the weight of the wheel hub.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 The present invention provides an embodiment of a multi-spoke wheel hub support structure, including an inner wheel hub 2 and a central shaft 4. The central shaft 4 is coaxially disposed at the center of the inner wheel hub 2. A multi-spoke mechanism 6 is connected between the central shaft 4 and the inner wheel hub 2. The structure also includes secondary spokes 602, a support mechanism 7, and the multi-spoke mechanism 6. The multi-spoke mechanism 6 includes main spokes 601 and secondary spokes 602 that extend from the ends of each main spoke 601 away from the central shaft 4 and are connected to the inner wheel hub 2. The secondary spokes 602 have a mounting groove 704 on one side of the surface facing the vehicle body. The support mechanism 7 includes a support ring 701, which is screwed and fixed in the mounting groove 704 by mounting bolts 703 to connect the secondary spokes 602 circumferentially as a whole. Furthermore, it also includes a support mechanism 7, which includes a support ring 701 with a circular hole 702 on its ring wall. Meanwhile, the multi-spoke mechanism 6 includes main spokes 601 and secondary spokes 602 that extend from the ends of each main spoke 601 away from the central axis 4 and are connected to the inner hub 2. A mounting groove 704 is correspondingly provided on the side surface of the secondary spokes 602 facing the vehicle body. The support ring 701 is screwed and fixed in the mounting groove 704 by mounting bolts 703. This structure, which connects the secondary spokes 602 circumferentially as a whole through the support ring 701, ensures that the hub has higher overall rigidity when subjected to lateral force or shear force. The outer surface of the main spoke 601 is integrally formed with spoke protrusions 603 extending along the length of the main spoke 601. The main spoke 601 is also provided with recessed grooves 604. The ring wall of the support ring 701 is provided with round holes 702. The multi-spoke mechanism 6 is fixed to the central shaft 4 by bolts 3 passing through the root of the main spoke 601. The end of the central shaft 4 away from the inner hub 2 is fixed with a mark 5. The root of the main spoke 601 connected to the central shaft 4 is formed into a wide base structure with a width greater than that of the middle section of the spoke. The tire 1 is installed on the outer periphery of the inner hub 2.

[0015] Working principle: The vehicle load is transmitted to the inner hub 2 through the tire 1. The load is transmitted between the inner hub 2 and the central shaft 4 through the multi-spoke mechanism 6. The multi-spoke mechanism 6 is fixed to the central shaft 4 by the fixing bolt 3 passing through the root of the main spoke 601. The root of the main spoke 601 is formed into a wide base structure with a width greater than that of the middle section of the spoke to ensure the connection strength. The main spoke 601 bears radial loads. The spoke protrusions 603 on the outer surface of the main spoke 601 enhance the structural strength of the main spoke 601. The recessed grooves 604 on the main spoke 601 optimize the cross-section and reduce weight. Each main spoke 601 extends into a secondary spoke 602 from the end away from the central axis 4. The secondary spoke 602 is connected to the inner hub 2. In the future, the load of the main spoke 601 will be distributed to multiple support points on the inner hub 2. When the wheel hub is subjected to lateral force or shear force, the support mechanism 7 plays a key role. The support ring 701 of the support mechanism 7 is screwed and fixed to the mounting groove 704 opened on the side surface of each secondary spoke 602 facing the vehicle body by mounting bolts 703. The support ring 701 connects all the secondary spokes 602 in the circumferential direction into a rigid whole. This rigid whole structure resists the lateral deformation of the wheel hub and distributes the shear force to the entire multi-spoke mechanism 6, thereby improving the overall rigidity of the wheel hub. The circular hole 702 opened on the ring wall of the support ring 701 reduces the weight of the support mechanism 7 and facilitates heat dissipation while ensuring strength. The end of the central shaft 4 away from the inner wheel hub 2 is fixed with a mark 5.
