In traditional technology, automobile wheels are mostly formed of cast iron alloy or alloy structural steel, or a single lightweight material. Cast iron alloy or alloy structural steel wheels have high strength, rigidity and toughness, but due to the high density of the material, they are heavy at the same thickness, and the design of the appearance is also limited due to the material properties. Single lightweight materials include aluminum alloy materials, whose density and elastic modulus are only one-third of that of steel materials. Therefore, more volume of aluminum alloy is needed to meet the requirements of product rigidity and strength. In addition, the preparation of aluminum alloy materials has problems such as high energy consumption and high carbon emissions. Therefore, while protecting the original load-bearing capacity, the application of lighter steel-aluminum structure wheels has become more and more widespread.

[0032] like Figures 1 to 5 As shown, the utility model provides a connection structure, which is used to connect the spoke 100 and the rim 200, and the connection structure includes a transition connector 300; one side of the transition connector 300 is connected to the inner wall of the outer ring 101 of the spoke 100, and the transition connector 300 has a connection portion 301 protruding from the outer ring 101, and the connection portion 301 is fixedly connected to the rim 200, and the wall thickness between the upper surface of the connection portion and the outer wall of the outer ring is D1, 2mm≤D1≤15mm.

[0033] In this embodiment, the connection structure is used to connect the spoke 100 and the rim 200, and includes a transition connector 300. One side of the transition connector 300 is connected to the spoke 100, and is connected to the rim 200 through a connection portion 301 of the transition connector 300 protruding from the outer ring 101 to achieve an effect of connecting the spoke 100 and the rim 200, thereby avoiding the situation that the spoke 100 and the rim 200 of the steel-aluminum structure wheel cannot be welded, and at the same time can also improve the installation efficiency. The fixed connection between the transition connector 300 and the spoke 100 can effectively ensure the connection strength between the transition connector 300 and the outer ring 101 of the spoke 100. The connection portion 301 protrudes from the spoke 100. After the connection portion 301 is fixedly connected to the spoke 100, the outer wall side of the connection portion 301 facing the outer ring 101 is the above-mentioned surface There is a certain distance between it and the outer wall of the outer ring 101 of the spoke 100, and the wall thickness range corresponding to the distance is D1, and 2mm≤D1≤15mm. After the aluminum wall is cast, it is directly fitted with the transition connector 300. The wall thickness D1 is also equivalent to the wall thickness of the aluminum wall located above the upper surface of the transition connector 300, which can effectively increase the connection strength and rigidity between the transition connector 300, the spoke 100 and the rim 200. It is directly affected by the wheel specifications and loads and is also related to the size of the brake. For example, for a 15-inch wheel hub, when the load is set to 480kg, the distance D1 is set to 4mm. This distance can effectively ensure the connection strength while ensuring that the weight of the wheel is not too large to the greatest extent, and at the same time can effectively control the production cost.

[0034] Optionally, the transition connector 300 can be integrally formed with the spoke 100 by casting. Correspondingly, the spoke 100 can also be prefabricated in advance and fixedly connected to the transition connector by screw connection, welding or other methods. The purpose of this method does not deviate from the design concept of the present invention and should belong to the protection scope of the present invention.

[0035] The transition piece 300 can be a circular iron sheet arranged along the entire circumference of the rim 200. Accordingly, the circular iron sheet can be divided into a plurality of iron sheets of the same size according to actual use conditions and then evenly spaced along the axial direction of the rim 200. This can save production costs while ensuring connection strength.

[0036] Among them, optional, such as Figure 3 and Figure 4 As described above, when the transition piece 300 and the spoke 100 are integrally cast, part of the transition piece 300 can be completely covered in the spoke 100, or part of the transition piece 300 can be protruded from the spoke 100. It can be set according to actual use requirements, and its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0037] Correspondingly, such as Figure 4 and Figure 5 As shown, the aluminum wall formed by casting the spoke 100 can be completely fitted with the inner wall of the rim 200, or can be partially fitted, and can be set according to actual use requirements. Its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0038] In order to reduce weight and lower production costs, at least one weight-reducing hole is provided on the connecting portion 301. The number of weight-reducing holes provided on the connecting portion can be increased or decreased according to actual usage conditions, and is not limited here. The purpose does not deviate from the design concept of the present utility model and should belong to the protection scope of the present utility model.

[0039] The transition piece 300 and the rim 200 are cast from cast iron alloy or alloy structural steel, preferably, low carbon steel.

[0040] The spoke 100 is made of lightweight materials, including aluminum alloy, and / or magnesium alloy, and / or high molecular polymer, preferably, aluminum alloy is selected.

[0041] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the wall thickness of the transition piece 300 between the end portion located inside the spoke 100 and the inner wall of the outer ring 101 is D2, and 4mm≤D2≤15mm.

[0042] In this embodiment, the transition connector 300 and the spoke 100 are integrally cast to effectively ensure the connection strength between the transition connector 300 and the outer ring 101 of the spoke 100. The wall thickness between the end of the transition connector 300 located inside the spoke 100 and the inner wall of the outer ring 101 is D2, and 4mm≤D2≤15mm. Setting the above wall thickness range can increase the connection strength between the transition connector 300 and the spoke 100, and will not cause cracking of the aluminum wall due to being too thin. Setting an upper limit on the wall thickness can effectively prevent excessive weight from affecting the use efficiency of the wheel.

[0043] According to an embodiment provided by the utility model, Figure 1 As shown, at least one reserved hole 302 is provided on the transition piece 300 , and the reserved hole 302 is used for casting the transition piece 300 and the spoke 100 .

[0044] In this embodiment, at least one reserved hole 302 is provided on the transition connector 300. During casting, the required molten aluminum is poured into the reserved hole 302. After solidification, the transition connector 300 and the outer ring 101 of the spoke 100 are connected together, thereby ensuring the connection strength between the transition connector 300 and the outer ring 101 of the spoke 100.

[0045] According to an embodiment provided by the utility model, Figure 1 As shown, the transition connector 300 also includes an embedded portion 303 , which is located in the outer ring 101 , and one end of the embedded portion 303 close to the rim 200 is connected to the connecting portion 301 , and the connecting portion 301 is disposed between the embedded portion 303 and the rim 200 .

[0046] In this embodiment, the transition connector 300 also includes an embedded portion 303, which is preset in the outer ring 101 and is connected to the connecting portion 301 at one end of the embedded portion 303 close to the rim 200. The connecting portion 301 protrudes from the outer ring 101. The embedded portion 303 is connected to the rim 200 through the connecting portion 301, so that the spoke 100 can be fixedly connected to the rim 200 through the transition connector 300 and have a certain connection strength.

[0047] According to an embodiment provided by the utility model, Figure 1 As shown, the embedded portion 303 includes a main section 3031 and a bending section 3032 , one end of the main section 3031 is connected to the end of the connecting portion 301 , and the other end is connected to one end of the bending section 3032 , and the other end of the bending section 3032 is bent toward the rim 200 .

[0048] In this embodiment, the embedded portion 303 includes a main body section 3031 and a bending section 3032. The main body section 3031 is directly connected to the end of the bending section 3032, and the end of the main body section 3031 away from the bending section 3032 is connected to the connecting portion 301, so as to achieve the effect of fixed connection between the embedded portion 303 and the rim 200 through the connecting portion 301. The other end of the bending section 3032 is bent toward the rim 200 to ensure that the embedded portion 303 will not slip off from the spoke 100 during use, thereby ensuring the connection strength between the transition connector 300 and the spoke 100.

[0049] Among them, optional, such as Figure 2 As shown, the bending section 3032 can also be set as a straight section. When the reserved casting integrated casting can have sufficient connection strength, the bending section 3032 can be set as a straight section. Accordingly, the number of the bending sections 3032 can also be one, two or more, wherein the direction of each bending section 3032 can extend toward the inside of the spoke 100. By setting the bending section 3032 to strengthen the connection relationship between the transition connector 300 and the rim 200, its purpose does not deviate from the design concept of the present invention and should belong to the protection scope of the present invention.

[0050] According to an embodiment provided by the utility model, Figure 1 As shown, the reserved hole 302 is located on the main body section 3031 .

[0051] In this embodiment, the reserved hole 302 is located on the main section 3031. By casting into the reserved hole 302, the transition connector 300 and the spoke 100 are integrally cast and formed. A part of the spoke 100 is accommodated in the reserved hole 302, and good connection strength is provided. The punching position of the reserved hole 302 needs to leave 3-35mm for the end position of the transition connector 300 to ensure the connection strength formed during casting.

[0052] Among them, optionally, the reserved hole 302 can also be opened on the bending section 3032, and its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0053] According to an embodiment provided by the utility model, Figure 1 As shown, the bending angle of the bending section 3032 is 10°-90°.

[0054] In this embodiment, the bending angle range between the bending section 3032 and the main section 3031 is 10°-90°, wherein preferably, the bending angle is set to 45°. The specific bending angle can be changed according to actual manufacturing conditions and is not limited here. Its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0055] The bending angle is set to ensure that the embedded portion 303 can be stably positioned in the spoke 100 and will not accidentally slip during use, thereby further strengthening the connection strength between the transition connector 300 and the spoke 100 .

[0056] According to an embodiment provided by the utility model, Figure 1 As shown, the length of the bending section 3032 is 2-10 mm.

[0057] In this embodiment, the length of the bending section 3032 is 2-10 mm, wherein, preferably, it is set such that when the length of the bending section 3032 is longer, a thicker outer ring 101 is required to cooperate with it. Therefore, the length of the bending section 3032 is set to 5 mm, which can ensure that the production cost will not increase while still having good structural strength between the spoke 100 and the bending section 3032.

[0058] Among them, it should be noted that the length of the bending section 3032 needs to change with the size change of the spoke 100 and the rim 200, and will also be affected by the wheel load and will change its length according to actual conditions. Its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.

[0059] According to an embodiment provided by the utility model, Figure 1 As shown, the reserved hole 302 is in a circular, oval, bar or square shape.

[0060] In this embodiment, the reserved hole 302 is in a shape of a circle, an ellipse, a bar or a square. The reserved hole 302 is set so that casting can be performed from the reserved hole 302 so that the transition connector 300 and the outer ring 101 of the spoke 100 are integrated and have good connection strength. Therefore, setting the reserved hole 302 to the above shapes can achieve the casting effect. At the same time, setting it to a circle, an ellipse, a bar or a square can also improve the overall aesthetics.

[0061] Among them, optionally, the shape of the reserved hole 302 can also be a rhombus, a pentagon or other shapes, the purpose of which does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.
