Description

Technical Field

[0001] The present invention relates to the technical field of automotive wheels, and particularly to a vehicle wheel. Background Art

[0002] A wheel hub is the inner contour of a tire, used to support the tire. The wheel hub is generally a metal component in the shape of a barrel and is centered on an axle. It is also one of the important components that make up the wheels of vehicles such as cars and motorcycles. Its quality directly affects the safety performance of the entire vehicle. Existing vehicle wheel hubs generally consist of a hub, a rim, and spokes. The hub is the component that connects the wheel and the axle. The rim is the component that mounts and supports the tire around the wheel. Both the inner and outer edges of the rim have flanges for limiting the tire. The spokes are the components that connect the rim and the hub on the wheel.

[0003] During the driving process of a vehicle, dust on the road enters the wheel hub through the gaps between adjacent spokes. The dust often contains hard particles such as sand grains and metal chips. These hard particles will accelerate the wear of the flange surface. The flange at the inner position of the rim is located inside the vehicle, and the space is relatively narrow, making it difficult to reach during cleaning, resulting in dust being more likely to accumulate at the flange at the inner position. Moreover, during the long-term use of the vehicle wheel hub, especially when the wheel turns, brakes suddenly, or accelerates, the tire will generate a large lateral force. Since the inner flange is closer to the center of gravity of the vehicle, the force it bears is relatively large. Being in this large stress state for a long time, the inner flange is more likely to suffer from fatigue damage, reducing the service life of the wheel hub. Most existing wheel hubs are designed as an integral structure and are difficult to disassemble. When the inner flange shows wear or fatigue damage, usually the entire wheel hub component needs to be replaced, increasing the maintenance cost and time, affecting the convenience of maintenance, and restricting the effective maintenance and replacement of the flange component. Summary of the Invention

[0004] The purpose of the present invention is to design a vehicle wheel hub to solve the above-mentioned technical deficiencies. The inner rim ring is connected to the rim assembly through a mounting plate and a first connecting member, ensuring the tight connection and reliable disassembly and assembly performance between the various parts of the vehicle wheel hub. At the same time, it also enables the inner hub ring to be disassembled and replaced separately when needed, reducing the maintenance cost and time, realizing the independent assembly and replacement of the various components of the automotive wheel hub, greatly improving the maintenance convenience of the vehicle wheel hub, and extending the service life of the vehicle wheel hub.

Specific embodiments

[0036] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 , a vehicle hub, including a hub body 1, a rim assembly 2 and an inner hub ring 3. The hub body 1 includes an integrally formed mounting part 11, an outer hub ring 12, and a plurality of spoke members 13 that are evenly distributed in a radially emitted manner. A docking ring 101 is provided at the edge of the inner side wall of the mounting part 11. Four mounting holes 106 that are distributed in an annular array penetrate through the mounting part 11. Inside the hollow area of the docking ring 101 corresponding to each mounting hole 106, the hollow area of the docking ring 101 is for the vehicle axle of the automobile to be sleeved and connected. Each mounting hole 106 is used for bolt fixation between the vehicle axle of the automobile and this vehicle hub. The spoke members 13 are used to connect the mounting part 11 and the outer hub ring 12.

[0038] Four locking rods 103 are provided on the outer hub ring 12. The locking rods 103 are arc-shaped plates. Each locking rod 103 is evenly distributed along the circumferential direction of the outer hub ring 12. An elastic hook part 104 is provided at the end of the locking rod 103.

[0039] Reference Figure 5 、 Figure 6, the rim assembly 2 includes an inner rim cylinder 21 and an outer rim cylinder 22. The inner rim cylinder 21 is sleeved inside the outer rim cylinder 22. A support frame 201 is provided on one side of the inner rim cylinder 21 close to the hub body 1. The support frame 201 is penetrated with a docking hole 202 for inserting the docking ring 101. Four positioning grooves 207 extending along its axial direction are penetrated on the inner side wall of the outer rim cylinder 22. The positioning grooves 207 respectively correspond to the locking rods 103. A limiting space 206 for limiting the locking rods 103 is formed by the cooperation between the inner wall of the positioning groove 207 and the outer wall of the inner rim cylinder 21. Preferably, the inner diameter of the ring formed by the positioning grooves 207 is smaller than the inner diameter of the ring formed by the locking rods 103.

[0040] The split design of the hub body 1, the rim assembly 2 and the inner hub ring 3 realizes the detachable connection of the components of the vehicle wheel hub. When assembling the vehicle wheel hub, the hub body 1 and the outer rim cylinder 22 are assembled together. By inserting the locking rod 103 into the outer rim cylinder 22, the positioning groove 207 is provided for the locking rod 103 to be inserted in place. The inner wall of the positioning groove 207 abuts against the hook portion 104 of the locking rod 103, causing the locking rod 103 to undergo elastic deformation. Until after the assembly of the hub body 1 and the outer rim cylinder 22 is completed, the hook portion 104 extends to the outside of the outer rim cylinder 22, the locking rod 103 resumes deformation and cooperates with the positioning groove 207. The inner wall of the positioning groove 207 is in contact and cooperation with the outer side wall of the locking rod 103, and the inner side wall of the outer rim cylinder 22 is in cooperation with the inner side wall of the locking rod 103, thereby limiting the outer rim cylinder 22 on the hub body 1 and completing the assembly operation between the hub body 1 and the outer rim cylinder 22. The locking rods 103 are distributed in a circular array, providing uniform structural support to the periphery of the hub body 1, helping to disperse the external force acting on the hub body 1 and improving the structural cooperation between the hub body 1 and the outer rim cylinder 22.

[0041] Reference Figure 2 , Figure 3 , Figure 7 , Figure 8, after the hub body 1 and the outer rim are assembled, the inner side walls of the locking rods 103 are all fitted with the inner side wall of the outer rim cylinder 22, so that the inner rim cylinder 21 can be sleeved into the outer rim cylinder 22 subsequently. During the process of inserting the inner rim cylinder 21 into the outer rim cylinder 22, the support frame 201 approaches the mounting portion 11. The outer side wall of the inner rim cylinder 21 and the inner side wall of the outer rim cylinder 22 limit the locking rods 103 through the respective limiting spaces 206. The socketing fit between the docking holes 202 and the docking rings 101 is used to guide the docking of the inner rim cylinder 21 and the outer rim cylinder 22 and the rotational fit. A connecting ring 203 is provided on the side of the inner rim cylinder 21 away from the hub body 1. A flaring groove 204 for the hook portion 104 to pass through is penetrated at the position of the connecting ring 203 relative to the limiting space 206. The inner wall of the flaring groove 204 includes a first guiding wall 209 and a second guiding wall 210. The first guiding wall 209 is inclined towards the opening of the flaring groove 204, and the first guiding wall 209 is used to avoid the locking rod 103. The second guiding wall 210 extends along the circumferential direction of the connecting ring 203, and the second guiding wall 210 is used to guide the rotation of the connecting ring 203 relative to the outer rim cylinder 22. By rotating the inner rim cylinder 21, the connecting ring 203 can avoid the hook portion 104 through the flaring groove 204, ensuring that the end face of the connecting ring 203 abuts against the end face of the outer rim cylinder 22 after the inner rim cylinder 21 and the outer rim cylinder 22 are socketed, and enabling the hook portion 104 to extend to the outside of the flaring groove 204. After that, by rotating the outer rim cylinder 22 to drive the connecting ring 203 to rotate, the opening of the flaring groove 204 penetrates through to the circumferential side wall of the connecting ring 203, and the spacing of the flaring groove 204 gradually increases in the direction close to its opening, so that the rotation of the connecting ring 203 can achieve the insertion or separation of the positioning groove 208 and the locking rod 103. A positioning groove 208 for socketing fit with the locking rod 103 is opened on the inner wall of the flaring groove 204. The inner wall of the positioning groove 208 is fitted with the first guiding wall 209. When the inner wall of the positioning groove 208 abuts against the hook portion 104, the opposite sides of the hook portion 104 and the inner rim cylinder 21 respectively abut against the two side walls of the connecting ring 203, thereby limiting the connecting ring 203 to complete the assembly operation of the rim assembly 2.

[0042] On the inner wall of the inner hub ring 3, four mounting plates 302 are arranged in an annular array. When the rim assembly 2 is completely installed, the inner wall of the clamping groove 208 abuts against the hook portion 104. At this time, the cavity formed between the hook portion 104 and the flared groove 204 can be plugged by the mounting plate 302, so as to guide the inner hub ring 3 to be assembled on the rim assembly 2 at the correct position. The end face of the outer rim cylinder 22 abuts and cooperates with the mounting plate 302. A first mounting position 205 is arranged on the end face of the outer rim cylinder 22. A first connecting member 303 is detachably connected to the mounting plate 302. The first mounting position 205 and the first connecting member 303 are detachably connected. Preferably, the first mounting position 205 is a connecting hole, and the first connecting member 303 is a bolt structure. The inner rim ring is connected to the rim assembly 2 through the mounting plate 302 and the first connecting member 303, which ensures the tight connection and reliable disassembly and assembly performance among various parts of the vehicle wheel hub. At the same time, the inner hub ring 3 can also be separately disassembled and replaced when needed, reducing the maintenance cost and time, realizing the independent assembly and replacement of various components of the vehicle wheel hub, greatly improving the maintenance convenience of the vehicle wheel hub, and prolonging the service life of the vehicle wheel hub.

[0043] A first rim 102 is formed at the edge of the outer hub ring 12, and a second rim 301 is formed at the edge of the inner hub ring 3. When the vehicle wheel hub is completely assembled, the first rim 102, the second rim 301 and the outer wall of the outer rim cylinder 22 cooperate to form a tire seat for limiting the tire.

[0044] Preferably, a fan-shaped ventilation opening 105 is formed between two adjacent spoke members 13. The ventilation opening 105 is used for heat dissipation. An installation opening 211 penetrates through the position of the support frame 201 relative to the ventilation opening 105. The installation opening 211 and the ventilation opening 105 are adapted in shape. The support frame 201 is detachably connected with a panel body 4 for covering the ventilation opening 105. A plurality of filter holes 401 penetrate through the panel body 4. The panel body 4 blocks dust from entering the inside of the rim assembly 2 through the respective filter holes 401.

[0045] On the inner wall of the installation opening 211, a second mounting position 212 and a third mounting position 213 are arranged opposite to each other. A second connecting member 402 is detachably connected to the outer side wall of the panel body 4. The second mounting position 212 is a connecting hole, and the second connecting member 402 is a bolt structure. An abutting plate 403 extending upward is formed at the edge of the panel body 4. The abutting plate 403 abuts against the inner wall of the ventilation opening 105. The panel body 4 is assembled on the ventilation opening 105 through the abutting plate 403 to ensure the position correspondence between the second connecting member 402 and the second mounting position 212. The panel body 4 is fixed in the installation opening 211 through the detachable connection between the second connecting member 402 and the second mounting position 212.

[0046] Reference Figure 3 、 Figure 4, Figure 5 , an elastic telescopic element 214 is arranged on the third mounting position 213. The second mounting position 212 is a connecting hole, and the second connecting piece 402 is a ball plunger bolt. The elastic end of the elastic telescopic element 214 abuts against the inner side wall of the panel body 4. The elastic end of the elastic telescopic element 214 abuts against the inner side wall of the panel body 4 to provide elastic support for the panel body 4. When the automobile wheel hub is in use, when the panel body 4 is impacted by an external force, while the elastic telescopic element 214 buffers it, the dust accumulated in the filter holes 401 is shaken off by the shaking of the panel body 4 itself.

[0047] The top of the abutting plate 403 extends to the outside of the ventilation opening 105 and is provided with a limiting plate 404. The two limiting plates 404 respectively correspond to two adjacent spoke members 13. Elastic pieces 405 are arranged on the inner side wall of the limiting plate 404. The elastic pieces 405 abut against the corresponding spoke members 13. The limiting plate 404 and its corresponding spoke member 13 are separated by the elastic pieces 405. While each elastic piece 405 provides elastic buffering, a shaking space for the panel body 4 is reserved, allowing the panel body 4 to shake limitedly. Moreover, each elastic piece 405 can compensate for the assembly error between the spoke member 13 and the panel body 4 through elastic deformation, so that the cooperation between the panel body 4 and its two adjacent spoke members 13 corresponding thereto is stable.

[0048] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
