Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a steel-aluminum wheel. Background Technology

[0002] Car wheels are components that contribute to a car's movement, appearance, and safety. Steel and aluminum wheels each have their advantages and disadvantages; therefore, combining steel rims with aluminum spokes in a composite wheel maximizes the advantages of both.

[0003] Since steel and aluminum cannot be directly connected by welding, the current steel-aluminum wheels are made by pre-embedding steel sheets inside the spokes during the casting of aluminum spokes, and then welding the steel sheets to the steel rim. Because steel and aluminum have different thermal shrinkage ratios, the entire casting process is too complicated and costly, and it also leads to lower product quality and lower production efficiency. Utility Model Content

[0004] (I) This utility model provides a steel-aluminum wheel, avoiding the technical problems of complex casting process and low wheel quality in the prior art.

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, embodiments of this utility model provide a steel-aluminum wheel, including a rim, spokes, and a fixing component;

[0007] The spokes are provided with a connecting part, which is located between the spokes and the rim. The connecting part is provided with a connecting groove, and a connecting ring is installed on the rim of the rim. The connecting ring is fitted into the connecting groove.

[0008] The fastener passes through the rim and the connecting portion in sequence to secure the rim and the spokes.

[0009] Furthermore, the wall thickness D of the connecting groove on the outer side of the spoke is ≥1.5mm.

[0010] Furthermore, the depth W of the connecting groove ranges from 3 to 15 mm, and the width L of the connecting groove ranges from 1.5 to 5.5 mm.

[0011] Furthermore, the fastener passes sequentially through the rim and the connecting portion from the bead seat of the rim.

[0012] Furthermore, the end of the fastener protrudes from the rim, and a first sealing layer is provided circumferentially on the end.

[0013] Furthermore, the fasteners are provided in multiple forms.

[0014] Furthermore, the plurality of said fasteners are arranged at intervals along the circumference of the wheel.

[0015] Furthermore, the connecting ring can be integral or separate.

[0016] Furthermore, the inner bottom wall of the connecting groove is a plane, an inclined plane, an arc surface, or a stepped surface.

[0017] Furthermore, a second sealing layer is provided between the connecting part and the wheel rim.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a steel-aluminum wheel, including a rim, spokes, and a fixing component. The spokes have a connecting portion located between the spokes and the rim, and the connecting portion has a connecting groove. Correspondingly, a connecting ring is provided on the rim. The connecting ring is embedded in the connecting groove, and the spokes and rim are connected together through an interference fit. The fixing component passes through the rim and the connecting portion in sequence to further fix the aluminum spokes and the steel rim. This connection method eliminates the need to pre-embed connecting components in the aluminum spokes during steel-aluminum wheel production. The interference fit between the connecting ring and the connecting groove provides a more stable connection structure. The fixing component passing through the rim and the connecting portion in sequence prevents low weld seam life, thus improving product quality, wheel performance, and service life.

[0031] like Figures 1 to 2 As shown, this utility model provides a steel-aluminum wheel, including a rim 100, spokes 200, and a fixing member 300; the spokes 200 are provided with a connecting part 201, which is located between the spokes 200 and the rim 100, and the connecting part 201 is provided with a connecting groove 202; the rim 101 of the rim 100 is correspondingly installed with a connecting ring 102, which is assembled into the connecting groove 202; the fixing member 300 passes through the rim 100 and the connecting part 201 in sequence to fix the rim 100 and the spokes 200.

[0032] In this embodiment, the steel-aluminum wheel includes a rim 100, spokes 200, and a fixing member 300. The spokes 200 have a connecting portion 201 located between the spokes 200 and the rim 100. The connecting portion 201 has a connecting groove 202, and correspondingly, a connecting ring 102 is provided on the rim 100. The connecting ring 102 is embedded in the connecting groove 202. Through an interference fit, the spokes 200 and the rim 100 are connected together. The fixing member 300 passes through the wheel sequentially. The rim 100 and the connecting part 201 further fix the aluminum spokes 200 and the steel rim 100. By using the above connection method to produce steel-aluminum wheels, it is not necessary to pre-embed connecting parts in the aluminum spokes 200. The interference fit between the connecting ring 102 and the connecting groove 202 makes the connection structure more stable. The fixing part 300 passes through the rim 100 and the connecting part 201 in sequence to fix it, thereby preventing the low life of the weld area, thus improving the product quality, and can also effectively improve the wheel performance and extend the service life of the wheel.

[0033] In this embodiment, the thickness of the connecting ring 102 is wider than that of the connecting groove 202 to facilitate an interference fit. Preferably, the wall thickness of the connecting ring 102 is set in the range of 2-10mm, and the width is set in the range of 8-30mm. The outer diameter of the connecting ring 102 matches the inner diameter of the spoke 200.

[0034] Optionally, during production and processing, the outer diameter of the connecting ring 102 can be directly machined to a size that matches the bead seat 103 for interference fit, according to actual production needs.

[0035] According to one embodiment of the present invention, such as Figure 1 As shown, the wall thickness D of the outer side of the connecting groove 202 corresponding to the spoke 200 is ≥1.5mm.

[0036] In this embodiment, the wall thickness D of the connecting groove 202 on the outer side of the spoke 200 is ≥1.5mm, so as to ensure the structural strength of the steel-aluminum wheel.

[0037] According to one embodiment of the present invention, such as Figure 1 As shown, the depth W of the connecting groove 202 ranges from 3 to 15 mm, and the width L of the connecting groove 202 ranges from 1.5 to 5.5 mm.

[0038] In this embodiment, the depth W of the connecting groove 202 is in the range of 3-15mm, and the width L of the connecting groove 202 is in the range of 1.5-5.5mm, so as to ensure that the connecting ring 102 has good structural strength for interference fit when sleeved.

[0039] According to one embodiment of the present invention, such as Figure 1As shown, the fastener 300 passes sequentially through the rim 100 and the connecting part 201 from the tire bead seat 103 of the rim 100.

[0040] In this embodiment, the fastener 300 passes sequentially through the rim 100 and the connecting portion 201 from above. The fastener 300 is driven into the rim 100 and the connecting portion 201 (i.e., the spoke 200) sequentially from the bead seat 103 of the rim 100, thereby fixing the rim 100 and the spoke 200 together. Correspondingly, the fastener 300 can also be driven into the spoke 200 from the corresponding position of the bead seat 103, with the same principle, and therefore will not be described further.

[0041] Optionally, a nail gun can be used to drive the fastener 300 in, or small holes can be pre-drilled and a press can be used to press the fastener 300 into the small holes. The small holes and the mating surfaces of the fastener 300 are interference-fitted to facilitate the fixed connection between the spokes 200 and the rim 100.

[0042] According to one embodiment of the present invention, such as Figure 2 As shown, the end of the fastener 300 protrudes from the rim 100, and a first sealing layer is provided circumferentially at the end.

[0043] In this embodiment, after the fastener 300 is driven into the rim 100 and spoke 200, a portion of its end will protrude beyond the surface of the rim 100. This protruding end can be welded to the rim 100 from above, and then ground smooth until the remaining surface of the fastener 300 is flush with the surface of the rim 100. Alternatively, it can be machined directly using a grinder or cutter to achieve the same flushness, thus ensuring the sealing of the rim 100. Optionally, sealant can be applied after welding to seal the protruding end of the fastener 300.

[0044] According to one embodiment of the present invention, the fastener 300 is provided with a plurality of fasteners.

[0045] In this embodiment, multiple fixed units can be provided, and the specific number can be increased or decreased as appropriate during processing according to actual usage requirements.

[0046] Preferably, the fastener 300 is a pin, which can be driven into the rim 100 and spoke 200 using a nail gun.

[0047] Optionally, the fastener 300 can also be a rivet, screw, bolt, or other component that is easy to drive into the rim 100 and spoke 200. Its purpose does not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.

[0048] According to one embodiment of the present invention, a plurality of fasteners 300 are arranged at intervals along the circumference of the wheel.

[0049] In this embodiment, multiple fasteners 300 are arranged at intervals along the circumference of the wheel, that is, they are arranged along the circumference of the rim 100. Preferably, the spacing between each fastener 300 is equal to ensure the quality of the steel-aluminum wheel.

[0050] According to one embodiment of the present invention, the connecting ring 102 is either an integral piece or a separate piece.

[0051] In this embodiment, when the connecting ring 102 is integral, a notch is also provided. After the connecting ring 102 is embedded into the connecting groove 202, the notch is welded and fixed so as to form the connecting ring 102 into a closed ring.

[0052] The connecting ring 102 can also be a split type. When the connecting ring 102 is a split type, after the two parts of the connecting ring 102 are respectively embedded into the connecting groove 202, the adjacent ends of the connecting ring 102 are welded and fixed to form a closed ring.

[0053] According to one embodiment of the present invention, such as Figure 1 As shown, the inner bottom wall of the connecting groove 202 is a plane, an inclined plane, an arc surface, or a stepped surface.

[0054] In this embodiment, by setting the inner bottom wall of the connecting groove 202 as one of a plane, inclined surface, arc surface or stepped surface, and prefabricating and adapting the connecting ring 102, the risk of the connecting ring 102 slipping out of the connecting groove 202 can be further reduced, so as to improve the quality of the wheel and thus increase its service life.

[0055] Optionally, the inner bottom wall of the connecting groove 202 can also be of other shapes, but its purpose does not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.

[0056] According to one embodiment of the present invention, such as Figure 1 As shown, a second sealing layer 400 is provided between the connecting part 201 and the rim 100.

[0057] In this embodiment, a second sealing layer 400 is provided at the connection between the bead seat 103 and the connecting part 201. Preferably, the second sealing layer 400 is composed of coated sealant or welded, so as to ensure that the sealing of the rim 100 surface is not damaged by the driven rivets.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
