Description

Technical Field

[0001] The present application relates to the field of automobile wheels, and in particular to a split wheel. Background Art

[0002] In the automotive industry, in order to meet complex industrial conditions and facilitate the replacement of severely worn wheel parts due to different wear conditions of wheel parts caused by different forces, research and improvements have been conducted on split wheels.

[0003] Currently, a Chinese invention patent with publication number CN104669929A, published on June 3, 2015, proposes an improved split wheel, comprising a wheel disc, a rim, and a metal fastening ring. The rim and the metal fastening ring are fixed to the wheel disc via bolts.

[0004] During installation, the rim part, the metal fastening ring part and the wheel disc part are connected so that the bolt holes are connected and connected as a whole by bolts.

[0005] According to the above technical solution, the bolt holes of different components need to be aligned during installation and then connected using bolts. During docking, the bolt holes of different components may be misaligned due to movement, and the bolt holes need to be docked again. Utility Model Content

[0006] In order to facilitate docking installation, the utility model provides a split wheel.

[0007] The utility model provides a split wheel, which adopts the following technical solutions:

[0008] A split wheel comprises a spoke, a rim and a plurality of connecting bolts, wherein a plurality of positioning holes are provided on the end face of the spoke close to the rim, and the plurality of positioning holes are evenly distributed along the circumference of the spoke, the rim comprises a rim supporting portion and a rim connecting portion, a plurality of positioning blocks are provided on the rim connecting portion, and one positioning block corresponds to one positioning hole, a plurality of bolt holes are also provided on the end face of the spoke close to the rim, and the plurality of bolt holes are evenly distributed along the circumference of the spoke, a plurality of through holes are provided on the rim connecting portion, and one through hole corresponds to one bolt hole, and the connecting bolts pass through the through holes and are threadedly connected in the bolt holes.

[0009] By adopting this technical solution, when assembling the wheel, the locating blocks are first inserted into the locating holes, thus completing the positioning of the rim and spokes, making it easier to subsequently secure the rim and spokes together using connecting bolts. When the wheel is in use, the locating blocks can replace the connecting bolts to withstand radial forces, reducing the probability of bolt deformation under stress and facilitating subsequent disassembly and maintenance of the wheel.

[0010] Optionally, one of the positioning blocks is a first positioning block, and the remaining positioning blocks are second positioning blocks, and the length of the first positioning block is longer than that of the second positioning block.

[0011] By adopting this technical solution, the first positioning block is first inserted into any positioning hole to complete the preliminary positioning between the spoke and the rim. Then, the spoke or rim is rotated around the axis of the first positioning block until the second positioning block is aligned with the other positioning hole. The second positioning block is then inserted into the other positioning hole to complete the positioning between the spoke and the rim. This positioning method can reduce the difficulty of positioning the spoke and the rim and improve positioning efficiency.

[0012] Optionally, a countersunk hole is coaxially formed at one end of the positioning hole close to the rim.

[0013] Due to the limitations of processing conditions, the connection between the positioning block and the rim is arc-shaped. By adopting this technical solution, after the positioning block is aligned and inserted into the positioning hole, the arc-shaped part of the connection between the positioning hole and the rim can be placed in the countersunk hole, which can make the opposite end faces of the rim and the spoke fit more closely, thereby improving the installation accuracy.

[0014] Optionally, a balancing hole is provided on the rim on the side where the first positioning block is provided.

[0015] Because the length of the first positioning block is longer than that of the second positioning block, the center of gravity of the rim will be offset from the axis. By adopting this technical solution, the balancing hole and the extra part of the first positioning block complement each other, so that the center of gravity of the rim is maintained on the axis of the rim, thereby improving stability.

[0016] Optionally, a cap is provided on the balancing hole, and the cap includes a cap portion and a bolt portion, the bolt portion is inserted into the balancing hole, and the cap portion is located outside the balancing hole.

[0017] By adopting this solution, the bolt portion of the cap is inserted into the balancing hole, and the balancing hole is not connected to the outside, which can prevent the balancing hole from being inconvenient to clean or affecting the balance due to the entry of debris.

[0018] Optionally, the cap is threadedly connected to the rim, and a hexagonal socket is provided on the top of the cap.

[0019] By adopting this solution, the cap is placed in the balancing hole and connected to the rim by rotating the cap with a screwdriver, which can increase the firmness of the cap connection and reduce the probability of the cap falling from the balancing hole.

[0020] Optionally, a spring is placed in the balancing hole.

[0021] By adopting this solution, the spring is placed in the balancing hole, and then the cap thread is connected to the rim through the balancing hole. When the cap is pressed against the spring, the spring provides an upward force to make the connection between the cap and the thread of the balancing hole tighter, thereby improving the reliability of the connection between the cap and the rim.

[0022] Optionally, the cap portion is configured to be arc-shaped.

[0023] By adopting this solution, after the cap is connected to the rim, the arc-shaped setting of the cap portion can reduce wind resistance.

[0024] In summary, the present invention has at least one of the following beneficial technical effects:

[0025] 1. The positioning blocks on the rim are connected to the positioning holes on the spokes, which facilitates the positioning and assembly of the rim and the spokes by bolts. At the same time, the positioning blocks replace the connecting bolts to bear radial force, reducing the probability of bolt deformation under stress and facilitating maintenance and disassembly of the wheel.

[0026] 2. When the positioning block is docked with the positioning hole, the setting of the countersunk hole makes the rim and the spoke fit more closely, thereby improving the installation accuracy.

[0027] 3. The balancing hole can keep the center of gravity of the rim on the axis, improving stability; the setting of the cap can prevent debris from entering the balancing hole, making it inconvenient to clean or affecting the balance; the setting of the arc-shaped cap can reduce the wind resistance when the wheel is in use.

DETAILED DESCRIPTION

[0034] Combine Figures 1 to 5 Further details are given for this application.

[0035] The embodiment of the utility model discloses a split wheel.

[0036] Reference Figure 1 A split wheel includes a spoke 2, a rim 1 and a plurality of connecting bolts 3. The rim 1 includes an integrally formed rim support portion 101 and a rim connecting portion 102. The rim connecting portion 102 is coaxially arranged on the inner circumferential surface of the rim support portion 101. A plurality of bolt holes 2012 are provided on the end surface of the spoke 2 close to the rim 1. The bolt holes 2012 are evenly distributed along the circumference of the spoke 2. A plurality of through holes 1023 are provided on the rim connecting portion 102. The through holes 1023 on the rim 1 correspond one-to-one to the bolt holes 2012 on the spoke 2.

[0037] Reference Figures 2 to 4 To facilitate the positioning and installation of the rim 1 and spoke 2, a plurality of positioning holes 2011 are provided on the end surface of the spoke 2 closest to the rim 1, evenly distributed along the circumference of the spoke 2. Positioning blocks are provided on the rim connecting portion 102, and each of the positioning blocks corresponds to the positioning holes 2011. The positioning blocks include a first positioning block 1021 and a plurality of second positioning blocks 1022, with the first positioning block 1021 being longer than the second positioning blocks 1022. To ensure a tighter fit between the rim 1 and the spoke 2, a countersunk hole 2013 coaxial with the positioning hole 2011 is provided on the side of the positioning hole 2011 facing the rim 1.

[0038] In this way, when assembling the wheel, first insert the first positioning block 1021 into any positioning hole 2011, and then rotate the spoke 2 or rim 1 around the axis of the first positioning block 1021 to align and insert the second positioning block 1022 with the other positioning holes 2011 to complete the positioning between the spoke 2 and the rim 1 and make them fit tightly; pass the connecting bolt 3 through the through hole 1023 on the rim 1 and connect it with the bolt hole 2012 on the spoke 2, tighten the bolt, and connect and fix the rim 1 and the spoke 2 with the bolt, which facilitates the connection between the rim 1 and the spoke 2 and the fixation of the bolt, while reducing the probability of the bolt being deformed by stress, and facilitating subsequent disassembly and maintenance.

[0039] Reference Figure 5In order to keep the center of gravity of the rim 1 at the axis center, a balancing hole 1024 is also provided on the side of the rim 1 where the first positioning block 1021 is provided. In order to prevent the balancing hole 1024 from entering with debris and becoming inconvenient to clean or even affecting its balancing effect, a cap 4 is also provided. In order to reduce weight, the cap 4 is made of a rubber material with lighter weight and better elasticity. The cap portion 401 of the cap 4 is set to an arc shape, and a hexagon socket 403 is provided on the top, which is bolted to the rim 1. When the cap 4 is connected to the rim 1, a spring 5 is also placed inside the balancing hole 1024 to increase the reliability of the connection between the cap 4 and the rim 1.

[0040] In this way, the spring 5 is placed in the balancing hole 1024, the cap 4 is docked with the balancing hole 1024 and the cap 4 is screwed, and the cap 4 is tightened. The spring 5 is compressed to provide an upward force to make the cap 4 and the rim 1 more tightly connected, reducing the probability of falling and achieving the sealing effect on the balancing hole 1024.

[0041] In summary, the implementation principles of this embodiment are:

[0042] After the first positioning block 1021 is positioned and connected with any one of the positioning holes 2011, the spoke 2 or the rim 1 is rotated around the axis of the first positioning block 1021, so that the other positioning blocks are aligned with the other positioning holes 2011 and inserted, the positioning between the spoke 2 and the rim 1 is completed and the two are tightly fitted; then the connecting bolt 3 is passed through the through hole 1023 on the rim 1 and connected with the bolt hole 2012 on the spoke 2 and the bolt is tightened to connect and fix the rim 1 and the spoke 2 together. In addition to providing the positioning function, the positioning block also bears radial force, reducing the probability of the bolt being deformed by force; the opening of the balancing hole 1024 ensures that the center of gravity of the rim 1 does not deviate from the axis; after the cap 4 closes the Pahang hole, it prevents debris from entering and affecting the balancing effect of the balancing hole 1024.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
