DETAILED DESCRIPTION
[0028] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0029] Example 1: Reference Figure 1 and Figure 2As shown, a sample aluminum wheel structure includes: a hub 1 and a middle plate 2 matched with the hub 1, a shrinking ring 3 is arranged on the inner side wall of the hub 1, a guide ring 4 matched with the shrinking ring 3 is arranged on the inner end face of the middle plate 2, and a guide slope 41 is arranged on the outer side wall of the guide ring 4; the shrinking ring 3 and the middle plate 2 are fixedly connected by a connecting assembly. The middle plate 2 and the hub 1 are both made of aluminum alloy.
[0030] When the center disk 2 and the wheel hub 1 are matched, the end face of one end of the center disk 2 faces the inside of the wheel hub 1, and this end face is the inner end face, while the other end face is the outer end face. The guide ring 4 is arranged inside the inner end face, and the guide ring 4 can be fixed together with the center disk 2 by integral molding, or the guide ring 4 and the center disk 2 can be fixed together by welding, which is not limited here.
[0031] The shrinking ring 3 is fixed to the inner wall of the hub 1 by welding, which makes it possible to adjust the position of the shrinking ring 3 on the inner wall of the hub 1 according to the thickness of the middle disk 2, so that the shrinking ring 3 can be welded at a specified position according to the middle disk 2 of different specifications. When the guide ring 4 and the shrinking ring 3 cooperate with each other, the outer end face of the middle disk 2 can just cooperate with the end face of the hub 1, making the overall structure look more beautiful.
[0032] The diameter of the guide ring 4 is smaller than the diameter of the center plate 2. The outer ring diameter of the guide ring 4 is the same as the inner ring diameter of the shrinking ring 3. When the shrinking ring 3 and the guide ring 4 are matched, the shrinking ring 3 is sleeved on the periphery of the guide ring 4.
[0033] In order to make it more convenient for the shrinking ring 3 to be sleeved on the periphery of the guide ring 4 , a guiding slope 41 is provided on the outer side wall of the guide ring 4 , so that the shrinking ring 3 can be sleeved on the periphery of the guide ring 4 more conveniently.
[0034] The connecting assembly in this embodiment includes a plurality of middle disk through holes 21 arranged in the circumferential direction of the middle disk 2, and a plurality of shrinking ring through holes 31 cooperating with the middle disk through holes 21 are arranged on the shrinking ring 3. The bolts 51 pass through the middle disk through holes 21 and the shrinking ring through holes 31 and are connected with the nuts 52.
[0035] In the present application, the connection assembly is a structure formed by the cooperation of the bolt 51 and the nut 52, so that the middle plate 2 and the wheel hub 1 can cooperate with each other, thereby fixing the middle plate 2 and the wheel hub 1 together. When it is necessary to replace the wheel hub 1 or the middle plate 2 with another style, the nut 52 and the bolt 51 can be separated, so as to replace the middle plate 2 or the wheel hub 1 with another style.
[0036] In addition, in this embodiment, in order to facilitate the bolt 51 to pass through the middle plate through hole 21 and the shrinking ring through hole 31, a first chamfer structure 22 is provided at one end of the middle plate through hole 21 close to the outer end surface, and a second chamfer structure 32 is provided at one end of the shrinking ring through hole 31 close to the middle plate 2. The first chamfer structure 22 forms a trumpet shape on the outer end surface of the middle plate through hole 21, and the second chamfer structure 32 forms a trumpet shape on the end surface of the shrinking ring through hole 31 close to the middle plate 2, so that the bolt 51 can pass through the middle plate through hole 21 and the shrinking ring through hole 31 more conveniently.
[0037] In this embodiment, by setting a connection component, the wheel hub 1 and the middle plate 2 can be detachably connected, so that different styles of wheel hubs 1 or middle plates 2 can be replaced according to actual conditions, so that only the middle plate 2 or only the wheel hub 1 needs to be developed, and then only the developed middle plate 2 (wheel hub 1) and the wheel hub 1 (middle plate 2) that does not need to be developed need to be installed. This can shorten the development cycle and reduce the development cost. The processed samples can be sent to customers for intuitive observation.
[0038] Example 2: Reference Figure 2 and Figure 3 As shown, a sample aluminum wheel structure includes: a hub 1 and a middle plate 2 matched with the hub 1, a shrinking ring 3 is arranged on the inner side wall of the hub 1, a guide ring 4 matched with the shrinking ring 3 is arranged on the inner end face of the middle plate 2, and a guide slope 41 is arranged on the outer side wall of the guide ring 4; the shrinking ring 3 and the middle plate 2 are fixedly connected by a connecting assembly. The middle plate 2 and the hub 1 are both made of aluminum alloy.
[0039] When the center disk 2 and the wheel hub 1 are matched, the end face of one end of the center disk 2 faces the inside of the wheel hub 1, and this end face is the inner end face, while the other end face is the outer end face. The guide ring 4 is arranged inside the inner end face, and the guide ring 4 can be fixed together with the center disk 2 by integral molding, or the guide ring 4 and the center disk 2 can be fixed together by welding, which is not limited here.
[0040] The shrinking ring 3 is fixed to the inner wall of the hub 1 by welding, which makes it possible to adjust the position of the shrinking ring 3 on the inner wall of the hub 1 according to the thickness of the middle disk 2, so that the shrinking ring 3 can be welded at a specified position according to the middle disk 2 of different specifications. When the guide ring 4 and the shrinking ring 3 cooperate with each other, the outer end face of the middle disk 2 can just cooperate with the end face of the hub 1, making the overall structure look more beautiful.
[0041] The diameter of the guide ring 4 is smaller than the diameter of the center plate 2. The outer ring diameter of the guide ring 4 is the same as the inner ring diameter of the shrinking ring 3. When the shrinking ring 3 and the guide ring 4 are matched, the shrinking ring 3 is sleeved on the periphery of the guide ring 4.
[0042] In order to make it more convenient for the shrinking ring 3 to be sleeved on the periphery of the guide ring 4 , a guiding slope 41 is provided on the outer side wall of the guide ring 4 , so that the shrinking ring 3 can be sleeved on the periphery of the guide ring 4 more conveniently.
[0043] The connecting assembly in this embodiment includes a plurality of middle disk through holes 21 arranged in the circumferential direction of the middle disk 2, a plurality of shrinking ring through holes 31 cooperating with the middle disk through holes 21 are arranged on the shrinking ring 3, and internal threads 53 are arranged in the shrinking ring through holes 31. After the bolts 51 pass through the middle disk through holes 21, they are fixedly connected with the internal threads 53 of the shrinking ring through holes 31.
[0044] Compared with Example 1, the present application is equivalent to setting the nut 52 in the shrink ring through-hole 31, so that there is no need to install the nut 52 separately, which is more convenient to operate than Example 1.
[0045] In addition, in this embodiment, in order to facilitate the bolt 51 to pass through the middle plate through hole 21 and the shrinking ring through hole 31, a first chamfer structure 22 is provided at one end of the middle plate through hole 21 close to the outer end surface, and a second chamfer structure 32 is provided at one end of the shrinking ring through hole 31 close to the middle plate 2. The first chamfer structure 22 forms a trumpet shape on the outer end surface of the middle plate through hole 21, and the second chamfer structure 32 forms a trumpet shape on the end surface of the shrinking ring through hole 31 close to the middle plate 2, so that the bolt 51 can pass through the middle plate through hole 21 and the shrinking ring through hole 31 more conveniently.
[0046] In this embodiment, by setting a connection component, the wheel hub 1 and the middle plate 2 can be detachably connected, so that different styles of wheel hubs 1 or middle plates 2 can be replaced according to actual conditions, so that only the middle plate 2 or only the wheel hub 1 needs to be developed, and then only the developed middle plate 2 (wheel hub 1) and the wheel hub 1 (middle plate 2) that does not need to be developed need to be installed. This can shorten the development cycle and reduce the development cost. The processed samples can be sent to customers for intuitive observation.
[0047] Example 3: Reference Figure 2 and Figure 4 As shown, a sample aluminum wheel structure includes: a hub 1 and a middle plate 2 matched with the hub 1, a shrinking ring 3 is arranged on the inner side wall of the hub 1, a guide ring 4 matched with the shrinking ring 3 is arranged on the inner end face of the middle plate 2, and a guide slope 41 is arranged on the outer side wall of the guide ring 4; the shrinking ring 3 and the middle plate 2 are fixedly connected by a connecting assembly. The middle plate 2 and the hub 1 are both made of aluminum alloy.
[0048] When the center disk 2 and the wheel hub 1 are matched, the end face of one end of the center disk 2 faces the inside of the wheel hub 1, and this end face is the inner end face, while the other end face is the outer end face. The guide ring 4 is arranged inside the inner end face, and the guide ring 4 can be fixed together with the center disk 2 by integral molding, or the guide ring 4 and the center disk 2 can be fixed together by welding, which is not limited here.
[0049] The shrinking ring 3 is fixed to the inner wall of the hub 1 by welding, which makes it possible to adjust the position of the shrinking ring 3 on the inner wall of the hub 1 according to the thickness of the middle disk 2, so that the shrinking ring 3 can be welded at a specified position according to the middle disk 2 of different specifications. When the guide ring 4 and the shrinking ring 3 cooperate with each other, the outer end face of the middle disk 2 can just cooperate with the end face of the hub 1, making the overall structure look more beautiful.
[0050] The diameter of the guide ring 4 is smaller than the diameter of the center plate 2. The outer ring diameter of the guide ring 4 is the same as the inner ring diameter of the shrinking ring 3. When the shrinking ring 3 and the guide ring 4 are matched, the shrinking ring 3 is sleeved on the periphery of the guide ring 4.
[0051] In order to make it more convenient for the shrinking ring 3 to be sleeved on the periphery of the guide ring 4 , a guiding slope 41 is provided on the outer side wall of the guide ring 4 , so that the shrinking ring 3 can be sleeved on the periphery of the guide ring 4 more conveniently.
[0052] The connection assembly in this embodiment includes a limiting protrusion 54 arranged at the opening of the hub 1, and a plurality of spaced limiting protrusions 55 are arranged on the outer ring wall of the middle plate 2. The limiting protrusions 55 are clamped between the limiting protrusions 55 and the shrinking ring 3.
[0053] Compared with Examples 1 and 2, the middle disc 2 and the wheel hub 1 need to be fixed by means of bolts 51 and nuts 52 during fixed installation. Although this method can fix the middle disc 2 and the wheel hub 1, it is very inconvenient during installation and disassembly. Therefore, in this embodiment, the installation is carried out by means of a limiting convex ring 54 and a limiting convex block 55, and the installation between the middle disc 2 and the wheel hub 1 can be achieved without rotating the bolts 51.
[0054] After the middle plate 2 and the wheel hub 1 are matched, the limiting protrusions 55 abut against the limiting protrusions 55, and the locking ring abuts against the inner side end surface of the middle plate 2, so that the wheel hub 1 can be stably fixed on the middle plate 2.
[0055] In this embodiment, by setting a connection component, the wheel hub 1 and the middle plate 2 can be detachably connected, so that different styles of wheel hubs 1 or middle plates 2 can be replaced according to actual conditions, so that only the middle plate 2 or only the wheel hub 1 needs to be developed, and then only the developed middle plate 2 (wheel hub 1) and the wheel hub 1 (middle plate 2) that does not need to be developed need to be installed. This can shorten the development cycle and reduce the development cost. The processed samples can be sent to customers for intuitive observation.
[0056] Example 4: Reference Figure 2 and Figure 5 As shown, a sample aluminum wheel structure includes: a hub 1 and a middle plate 2 matched with the hub 1, a shrinking ring 3 is arranged on the inner side wall of the hub 1, a guide ring 4 matched with the shrinking ring 3 is arranged on the inner end face of the middle plate 2, and a guide slope 41 is arranged on the outer side wall of the guide ring 4; the shrinking ring 3 and the middle plate 2 are fixedly connected by a connecting assembly. The middle plate 2 and the hub 1 are both made of aluminum alloy.
[0057] When the center disk 2 and the wheel hub 1 are matched, the end face of one end of the center disk 2 faces the inside of the wheel hub 1, and this end face is the inner end face, while the other end face is the outer end face. The guide ring 4 is arranged inside the inner end face, and the guide ring 4 can be fixed together with the center disk 2 by integral molding, or the guide ring 4 and the center disk 2 can be fixed together by welding, which is not limited here.
[0058] The shrinking ring 3 is fixed to the inner wall of the hub 1 by welding, which makes it possible to adjust the position of the shrinking ring 3 on the inner wall of the hub 1 according to the thickness of the middle disk 2, so that the shrinking ring 3 can be welded at a specified position according to the middle disk 2 of different specifications. When the guide ring 4 and the shrinking ring 3 cooperate with each other, the outer end face of the middle disk 2 can just cooperate with the end face of the hub 1, making the overall structure look more beautiful.
[0059] The diameter of the guide ring 4 is smaller than the diameter of the center plate 2. The outer ring diameter of the guide ring 4 is the same as the inner ring diameter of the shrinking ring 3. When the shrinking ring 3 and the guide ring 4 are matched, the shrinking ring 3 is sleeved on the periphery of the guide ring 4.
[0060] In order to make it more convenient for the shrinking ring 3 to be sleeved on the periphery of the guide ring 4 , a guiding slope 41 is provided on the outer side wall of the guide ring 4 , so that the shrinking ring 3 can be sleeved on the periphery of the guide ring 4 more conveniently.
[0061] The connecting assembly in this embodiment includes a first magnetic ring 56 embedded in the shrinking ring 3, and a plurality of second magnetic blocks 57 are arranged in the circumferential direction of the middle disk 2. The first magnetic blocks and the second magnetic blocks 57 attract each other, so that the middle disk 2 and the hub 1 are fixedly connected.
[0062] The middle plate 2 is provided with inlay holes 23, which are evenly distributed along the circumferential direction, and the second magnetic block 57 is arranged in the inlay holes 23. The inlay holes 23 can facilitate the removal of the second magnetic block 57, and facilitate the reuse of the second magnetic block 57.
[0063] In Example 3, although the installation is more convenient than the structures of the connection components in Example 1 and the embodiment, in the specific installation process, a press is required to press the limiting protrusion 55 on the middle plate 2 into the limiting protrusion 54 of the shrinking ring 3. Therefore, equipment is required during installation, or even if it is installed manually, it takes a lot of effort, so there are certain inconveniences in assembly.
[0064] Therefore, in this embodiment, the installation between the center disk 2 and the wheel hub 1 is achieved by the cooperation between the first magnetic ring 56 and the second magnetic block 57 and by utilizing the mutual attraction between the first magnetic ring 56 and the second magnetic block 57, and the installation is very convenient.
[0065] In this embodiment, by setting a connection component, the wheel hub 1 and the middle plate 2 can be detachably connected, so that different styles of wheel hubs 1 or middle plates 2 can be replaced according to actual conditions, so that only the middle plate 2 or only the wheel hub 1 needs to be developed, and then only the developed middle plate 2 (wheel hub 1) and the wheel hub 1 (middle plate 2) that does not need to be developed need to be installed. This can shorten the development cycle and reduce the development cost. The processed samples can be sent to customers for intuitive observation.
