Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, specifically a stress-dispersing anti-fracture wheel hub structure. Background Technology

[0002] The wheel hub is a core component of the wheels of vehicles such as cars and motorcycles. It connects the tire to the axle, providing support and transmitting power. Its structure typically consists of three parts: the rim, the spokes, and the hub disc. The rim directly mounts the tire and bears the weight of the vehicle and the impact of the road surface. The spokes are distributed radially or in a mesh pattern to enhance structural strength and distribute stress. The hub disc is connected to the axle through a bearing to ensure smooth rotation. Modern wheel hubs are mostly made of aluminum alloy or carbon fiber, balancing lightweight and high strength. Some high-end models are also equipped with ventilation holes or heat dissipation designs to optimize braking performance. The design of the wheel hub directly affects the vehicle's handling, comfort, and safety, and is one of the key factors in vehicle performance.

[0003] In existing technologies, the bolt hole area of ​​the wheel hub center disc is prone to cracking. During vehicle operation, the bolt hole bears the enormous tightening force from the bolt and the dynamic load of the vehicle. Under long-term complex stress environment, the material at the bolt hole is prone to fatigue cracks. With the increase of service time, the cracks propagate and eventually lead to cracking, which seriously affects driving safety. The wheel hub groove has insufficient strength and cannot effectively bear the weight of the vehicle and various impacts during driving, which reduces the overall load-bearing capacity of the wheel hub and increases the risk of wheel hub deformation or even damage, posing a great hidden danger to the stable operation of the vehicle. Therefore, we need a stress-dispersed anti-fracture wheel hub structure. Utility Model Content

[0004] The purpose of this invention is to provide a stress-dispersing anti-fracture wheel hub structure to solve the problems mentioned in the background art, such as the easy cracking of the screw hole in the center disc of the existing wheel hub and the insufficient strength of the groove affecting the load-bearing capacity of the wheel hub.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stress-dispersing anti-fracture hub structure, comprising a central disc, a stress-dispersing component disposed inside the central disc, a bearing welded to the bottom of the central disc, a reinforcing component welded to the outer wall of the bearing, the stress-dispersing component including screw holes, a thickened layer integrally connected to the top of the central disc, a plurality of screw holes being circumferentially formed on the thickened layer, a groove being formed on the top of the central disc, an annular reinforcing rib welded inside the groove, radial reinforcing ribs welded to the outer wall of the annular reinforcing rib, and straight reinforcing ribs welded inside the groove.

[0006] Preferably, the screw hole and the thickened layer form a fixed structure, and the thickened layer is a ring structure surrounding the screw hole, and the inner diameter of the ring structure is adapted to the diameter of the screw hole.

[0007] Preferably, there are multiple radial reinforcing ribs, and the multiple radial reinforcing ribs are arranged radially with the annular reinforcing rib as the center.

[0008] Preferably, there are multiple straight reinforcing ribs, and all of the multiple straight reinforcing ribs are fixed to the inner walls of both sides of the groove inside the central disk by welding.

[0009] Preferably, the reinforcement component includes a fixing plate, which is welded to the outer wall of the bearing. A support tube is welded to the bottom of the fixing plate, and an angled reinforcing rib is welded to the top of the fixing plate.

[0010] Preferably, the fixing plate and the support tube form a fixing structure, and there are two fixing plates, which surround the outer wall of the bearing, and the support tube is welded between the two fixing plates.

[0011] Preferably, there are multiple oblique reinforcing ribs, and the multiple oblique reinforcing ribs are welded at equal intervals to the top of the fixing plate, and the oblique reinforcing ribs are welded around the outer wall of the bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problems of easy cracking of the bolt holes in the center disc of the wheel hub and insufficient strength of the groove affecting the load-bearing capacity of the wheel hub in the prior art, this application provides a thickened layer on one side of the bolt hole to evenly distribute the stress when the bolt hole and bolt connection are under stress. A ring-shaped reinforcing rib is provided in the groove of the center disc to enhance the local strength and rigidity of the groove. Radial reinforcing ribs are arranged radially along the outer wall of the ring-shaped reinforcing rib to further distribute the load stress. Straight reinforcing ribs are provided in the groove to improve the local resistance to deformation. This achieves comprehensive prevention of groove cracking, reduces the risk of cracking around the bolt holes, improves the overall load-bearing capacity, structural stability and durability of the wheel hub, and ensures the safe and reliable operation of the wheel hub. 2. To address the problems of insufficient connection strength, concentrated stress leading to unstable operation, easy deformation, and limited load-bearing capacity in existing wheel hub structures, this application proposes to enhance the connection strength between the bearing and the fixed plates by welding two fixed plates to the outer wall of the bearing and installing multiple support tubes between the two fixed plates. Additionally, angled reinforcing ribs are installed on one side of the fixed plates. This effectively disperses the stress, improving the wheel hub's operational stability, strengthening the structure, preventing deformation, significantly enhancing the overall stability and load-bearing capacity of the wheel hub, and extending its service life.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] This utility model embodiment provides a stress-dispersing anti-fracture wheel hub structure, such as... Figure 1 and Figure 3 As shown, the device includes a central disk 1, a stress-dispersing component 2 disposed inside the central disk 1, a bearing 3 welded to the bottom of the central disk 1, a reinforcing component 4 welded to the outer wall of the bearing 3, the stress-dispersing component 2 including screw holes 201, a thickened layer 202 integrally connected to the top of the central disk 1, multiple screw holes 201 circumferentially formed on the thickened layer 202, a groove 203 formed on the top of the central disk 1, annular reinforcing ribs 204 welded inside the groove 203, radial reinforcing ribs 205 welded to the outer wall of the annular reinforcing ribs 204, and straight reinforcing ribs 206 welded inside the groove 203. A thickened layer 202 is provided on one side of the screw hole 201, which can evenly distribute stress when under force, reduce local stress concentration, and reduce the risk of cracking around the screw hole 201. A ring-shaped reinforcing rib 204 is provided in the groove 203 of the central disc 1 to enhance local strength and rigidity, evenly distribute stress, and prevent deformation and cracking. Radial reinforcing ribs 205 are provided radially along the outer wall of the ring-shaped reinforcing rib 204 to further distribute load stress and avoid local cracking. A reinforcing rib 206 is also provided in the groove 203 to improve the deformation resistance. Together with the previous two, it can prevent the groove 203 from cracking in all directions and ensure the safe operation of the wheel hub.

[0017] Furthermore, such as Figure 3As shown, the edge of the thickened layer 202 is integrally connected with an annular structure protruding to the circumference. The screw hole 201 is located in the annular structure. The screw hole 201 and the thickened layer 202 form a fixed structure. The shape of the thickened layer 202 is an annular structure surrounding the screw hole 201. The inner diameter of the annular structure is matched with the diameter of the screw hole 201. By setting the thickened layer 202, the connection strength can be enhanced, the risk of cracking around the screw hole 201 can be reduced, and the reliability and durability of the part connection can be ensured.

[0018] Furthermore, such as Figure 3 As shown, there are multiple radial reinforcing ribs 205, and the multiple radial reinforcing ribs 205 are arranged radially around the annular reinforcing rib 204. By setting multiple radial reinforcing ribs 205, the load stress borne by the annular reinforcing rib 204 can be effectively dispersed, avoiding structural cracking caused by stress concentration, while enhancing the load-bearing capacity and durability of the wheel hub, forming a more stable stress dispersion system.

[0019] Furthermore, such as Figure 3 As shown, there are multiple straight reinforcing ribs 206, and all of them are welded and fixed to the inner walls of both sides of the groove 203 inside the central disk 1. By setting the straight reinforcing ribs 206, the deformation resistance of the local structure of the groove 203 can be significantly improved, the concentrated stress can be effectively dispersed, and the groove 203 can be prevented from cracking or collapsing due to excessive force. At the same time, the overall structural stability of the central disk 1 is enhanced, ensuring its load-bearing performance under high load conditions.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the reinforcement component 4 includes a fixing plate 401, which is welded to the outer wall of the bearing 3. A support tube 402 is welded to the bottom of the fixing plate 401, and an angled reinforcing rib 403 is welded to the top of the fixing plate 401. Two fixing plates 401 are welded to the outer wall of the bearing 3 to enhance their connection strength, disperse the force, and improve the operational stability. Multiple support tubes 402 are provided between the two fixing plates 401 for support. The angled reinforcing rib 403 on one side of the fixing plate 401 can disperse the force on the bearing 3 in multiple directions, strengthen the connection between the fixing plate 401 and the bearing 3, prevent structural deformation, and effectively improve the overall stability and load-bearing capacity of the wheel hub.

[0021] Furthermore, such as Figure 4 As shown, the fixing plate 401 and the support tube 402 form a fixed structure, and there are two fixing plates 401. The fixing plates 401 surround the outer wall of the bearing 3, and the support tube 402 is welded between the two fixing plates 401. By setting the fixing plates 401, the connection strength of the bearing 3 can be enhanced, the force can be distributed, and the operational stability can be improved.

[0022] Furthermore, such as Figure 4As shown, there are multiple oblique reinforcing ribs 403, and the multiple oblique reinforcing ribs 403 are welded at equal intervals to the top of the fixing plate 401. The oblique reinforcing ribs 403 are welded around the outer wall of the bearing 3. By setting multiple oblique reinforcing ribs 403, the force on the bearing 3 can be dispersed in multiple directions, the connection strength between the fixing plate 401 and the bearing 3 can be enhanced, structural deformation can be prevented, and the overall stability and load-bearing capacity can be improved.

[0023] Working principle: By setting a thickened layer 202 on one side of the screw hole 201, stress can be more evenly distributed when the screw hole 201 is connected to the bolt, reducing local stress concentration and thus reducing the risk of cracking around the screw hole 201. The annular reinforcing rib 204 in the groove 203 of the center disc 1 can significantly enhance the local strength and rigidity of the groove 203, evenly dispersing stress from all directions, preventing deformation or cracking of the groove 203, and improving the overall load-bearing capacity and structural stability of the center disc 1. Radial reinforcing ribs 205 are arranged radially along the outer wall of the annular reinforcing rib 204, which can further disperse the load stress borne by the annular reinforcing rib 204, avoiding excessive local stress leading to cracking, and enhancing the load-bearing capacity of the hub. The system combines strength and durability to form a stable stress dispersion system. In addition, straight reinforcing ribs 206 are set in the groove 203, which can effectively improve the deformation resistance of the local structure. Together with the annular reinforcing ribs 204 and radial reinforcing ribs 205, they can prevent the groove 203 from cracking in all directions, ensuring the safe and reliable operation of the wheel hub. Two fixing plates 401 are welded to the outer wall of the bearing 3 to enhance its connection strength, disperse the force, and improve the operational stability. Multiple support tubes 402 are set between the two fixing plates 401 for support. The oblique reinforcing ribs 403 on one side of the fixing plate 401 can disperse the force on the bearing 3 in multiple directions, strengthen the connection between the fixing plate 401 and the bearing 3, prevent structural deformation, and effectively improve the overall stability and load-bearing capacity of the wheel hub.
