Description

Technical Field

[0001] The present invention relates to the technical field of automobile wheels, and in particular to a vehicle wheel hub. Background Art

[0002] The wheel hub is the inner profile of the tire, used to support it. A generally cylindrical metal component mounted centrally on an axle, the wheel hub is a crucial component of the wheels of vehicles like cars and motorcycles, and its quality directly impacts the safety of the entire vehicle. Existing vehicle wheels typically consist of a hub, rim, and spokes. The hub connects the wheel to the axle, the rim is the part around the wheel that mounts and supports the tire, and both the inner and outer edges of the rim have flanges for retaining the tire. The spokes connect the rim and hub.

[0003] When a vehicle is driving, dust on the road enters the wheel hub through the gap between two adjacent wheel spokes. The dust often contains hard particles such as sand and metal debris. These hard particles will accelerate the wear of the wheel rim surface. The rim on the inner side of the rim is located inside the vehicle, and the space is relatively narrow. It is not easy to reach when cleaning, which makes it easier for dust to accumulate on the inner side of the rim. Moreover, when the vehicle wheel hub is used for a long time, especially when the wheel is turning, braking suddenly or accelerating, the tire will generate a large lateral force. Since the inner rim is closer to the center of gravity of the vehicle, the force it bears is relatively large. When it is in this large stress state for a long time, the inner rim is more prone to fatigue damage, which reduces the service life of the wheel hub. Most of the existing wheel hubs are designed as an integrated structure and are difficult to disassemble. When the inner rim is worn or fatigue damaged, the entire hub component usually needs to be replaced, which increases maintenance costs and time, affects the convenience of maintenance, and limits the effective maintenance and replacement of the rim components.

[0040] The present invention will be further described below with reference to the accompanying drawings and examples.

[0041] refer to Figure 1 、 Figure 2 、 Figure 3 A vehicle wheel hub comprises a hub body 1, a rim assembly 2, and an inner hub 3. The hub body 1 includes an integrally formed mounting portion 11, an outer hub 12, and a plurality of spokes 13 evenly distributed in a radial pattern. A docking ring 101 is provided on the edge of the inner sidewall of the mounting portion 11. The mounting portion 11 is provided with four mounting holes 106 arranged in an annular array. Each mounting hole 106 is located within a hollow region of the docking ring 101. The hollow region of the docking ring 101 is provided for insertion and connection of a vehicle axle. Each mounting hole 106 is provided for bolting the vehicle axle to the vehicle hub. The spokes 13 are used to connect the mounting portion 11 to the outer hub 12.

[0042] The outer hub ring 12 is provided with four locking rods 103 . The locking rods 103 are arc-shaped plates. The locking rods 103 are evenly distributed along the circumference of the outer hub ring 12 . The ends of the locking rods 103 are provided with elastic hook portions 104 .

[0043] refer to Figure 5 、 Figure 6The rim assembly 2 includes an inner rim tube 21 and an outer rim tube 22. The inner rim tube 21 is sleeved within the outer rim tube 22. A support frame 201 is provided on the side of the inner rim tube 21 close to the hub body 1. The support frame 201 has a docking hole 202 extending therethrough for the docking ring 101 to be inserted therein. The inner sidewall of the outer rim tube 22 has four axially extending positioning grooves 207 extending therethrough. The positioning grooves 207 correspond to the locking rods 103, respectively. The inner walls of the positioning grooves 207 cooperate with the outer wall of the inner rim tube 21 to form a limiting space 206 for retaining the locking rods 103. Preferably, the inner diameter of the ring formed by each positioning groove 207 is smaller than the inner diameter of the ring formed by each locking rod 103.

[0044] The separate design of the hub body 1, the rim assembly 2 and the inner hub ring 3 enables detachable connection of the various components of the vehicle hub. When assembling the vehicle wheel hub, the wheel hub body 1 and the outer rim tube 22 are assembled together, and the locking rod 103 is inserted into the outer rim tube 22 through the positioning groove 207. The inner wall of the positioning groove 207 is tightly pressed against the hook portion 104 of the locking rod 103, causing the locking rod 103 to elastically deform until the wheel hub body 1 and the outer rim tube 22 are assembled. The hook portion 104 extends to the outside of the outer rim tube 22, and the locking rod 103 recovers its deformation and cooperates with the positioning groove 207. The inner wall of the positioning groove 207 contacts and cooperates with the outer wall of the locking rod 103, and the inner side wall of the outer rim tube 22 cooperates with the inner side wall of the locking rod 103, thereby limiting the outer rim tube 22 on the wheel hub body 1, completing the assembly operation between the wheel hub body 1 and the outer rim tube 22. The locking rods 103 are distributed in an annular array, providing uniform structural support to the periphery of the hub body 1 , helping to disperse external forces acting on the hub body 1 , and improving the structural fit between the hub body 1 and the outer rim tube 22 .

[0045] refer to Figure 2 、 Figure 3 、 Figure 7 、 Figure 8When the wheel hub body 1 and the outer rim are assembled, the inner side walls of each locking rod 103 cooperate with the inner side walls of the outer rim tube 22 so that the inner rim tube 21 can be inserted into the outer rim tube 22. During the process of inserting the inner rim tube 21 into the outer rim tube 22, the support frame 201 is close to the mounting portion 11, and the outer side walls of the inner rim tube 21 and the inner side walls of the outer rim tube 22 are limited by the limiting spaces 206 to limit the locking rods 103. The inner rim tube 21 and the outer rim tube 22 are guided to be aligned and rotated together by the sleeve fit between the docking hole 202 and the docking ring 101. A connecting ring 203 is provided on the side of the inner rim tube 21 away from the wheel hub body 1. The connecting ring 203 is penetrated by an expanding groove 204 for the hook portion 104 to pass through at the position relative to the limiting space 206. The inner wall of the expanding groove 204 includes a first guide wall 209 and a second guide wall 210. The first guide wall The first guide wall 209 is arranged to avoid the locking rod 103, and the second guide wall 210 extends along the circumference of the connecting ring 203. The second guide wall 210 is used to guide the connecting ring 203 to rotate relative to the outer rim tube 22. By rotating the inner rim tube 21, the connecting ring 203 is allowed to pass through the expanding groove 204 to avoid the hook portion 104, ensuring that the connecting ring 203 and the end face of the outer rim tube 22 are in conflict after the inner rim tube 21 and the outer rim tube 22 are connected, so that the hook portion 104 extends to the outside of the expanding groove 204. Thereafter, by rotating the outer rim tube 22 to drive the connecting ring 203 to rotate, the opening of the expanding groove 204 penetrates the circumferential side wall of the connecting ring 203, and the spacing of the expanding groove 204 gradually increases along the direction close to its opening, so that the rotation of the connecting ring 203 can realize the insertion or separation of the positioning groove 208 and the locking rod 103. The inner wall of the flared groove 204 is provided with a locking groove 208 that is plugged into the locking rod 103. The inner wall of the locking groove 208 cooperates with the first guide wall 209. When the inner wall of the locking groove 208 contacts the hook portion 104, the hook portion 104 and the opposite sides of the inner rim tube 21 respectively abut against the two side walls of the connecting ring 203, thereby limiting the connecting ring 203 to realize the assembly operation of the rim assembly 2.

[0046] Four mounting plates 302 are arranged in a circular array on the inner sidewall of the inner hub 3. When the rim assembly 2 is installed, the inner wall of the latching groove 208 abuts against the hook portion 104. The cavity formed between the hook portion 104 and the flared groove 204 allows the mounting plates 302 to be inserted, thereby guiding the inner hub 3 to be assembled on the rim assembly 2 in the correct position. The end surface of the outer rim tube 22 abuts against the mounting plates 302. A first mounting position 205 is provided on the end surface of the outer rim tube 22. A first connector 303 is detachably connected to the mounting plate 302, and the first mounting position 205 and the first connector 303 are detachably connected. Preferably, the first mounting position 205 is a connecting hole, and the first connector 303 is a bolt structure. The inner wheel rim is connected to the wheel rim assembly 2 via the mounting plate 302 and the first connecting member 303, ensuring a tight connection between the various parts of the vehicle hub and reliable assembly and disassembly performance. At the same time, the inner wheel hub 3 can be disassembled and replaced separately when needed, reducing maintenance costs and time, and realizing the independent assembly and replacement of the various components of the automobile hub, greatly improving the maintenance convenience of the vehicle hub and extending the service life of the vehicle hub.

[0047] The edge of the outer wheel hub 12 is formed with a first rim 102, and the edge of the inner wheel hub 3 is formed with a second rim 301. When the vehicle hub is assembled, the first rim 102, the second rim 301 and the outer wall of the outer rim tube 22 cooperate to form a tire seat for limiting the tire.

[0048] Preferably, fan-shaped vents 105 are formed between two adjacent spokes 13 for dissipating heat. A mounting opening 211 is formed through the support frame 201 at a position corresponding to the vent 105. The mounting opening 211 and the vent 105 are adapted in shape. The support frame 201 is detachably connected to a panel body 4 that covers the vent 105. The panel body 4 has a plurality of filter holes 401 formed therethrough, which prevent dust from entering the interior of the rim assembly 2 through the filter holes 401.

[0049] The inner wall of the mounting opening 211 is provided with a second mounting position 212 and a third mounting position 213 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. The second connecting member 402 is a bolt structure. An upward extending abutment plate 403 is formed on the edge of the panel body 4. The abutment plate 403 abuts against the inner wall of the vent 105. The panel body 4 is assembled on the vent 105 through the abutment plate 403 to ensure that the second connecting member 402 corresponds to the second mounting position 212. The panel body 4 is fixed in the mounting opening 211 through the detachable connection between the second connecting member 402 and the second mounting position 212.

[0050] refer to Figure 3 、 Figure 4、 Figure 5 The third mounting position 213 is provided with an elastic telescopic element 214. The second mounting position 212 is a connecting hole. The second connecting member 402 is a ball-type screw. The elastic end of the elastic telescopic element 214 abuts against the inner sidewall of the panel body 4. The elastic end of the elastic telescopic element 214 abuts against the inner sidewall of the panel body 4 to provide elastic support for the panel body 4. When the automobile wheel hub is in use, the panel body 4 is subjected to external impact. The elastic telescopic element 214 not only cushions the impact, but also utilizes the shaking of the panel body 4 to shake off dust accumulated in the filter holes 401.

[0051] The top of the abutment plate 403 extends to the outside of the vent 105 and is provided with a limiting plate 404. The two limiting plates 404 correspond to the two adjacent spokes 13 respectively. The inner wall of the limiting plate 404 is provided with a spring piece 405, which abuts on the corresponding spoke 13. The limiting plate 404 and its corresponding spoke 13 are separated by the spring piece 405. Each spring piece 405 provides elastic buffering while reserving a shaking space for the panel body 4, allowing the panel body 4 to shake limitedly, and each spring piece 405 can compensate for the assembly error between the spoke 13 and the panel body 4 through elastic deformation, so that the panel body 4 and its corresponding two adjacent spokes 13 fit stably.

[0052] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
