Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a steel-aluminum wheel with edging. 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, existing steel-aluminum wheels currently embed steel sheets inside the spokes during the casting of aluminum spokes, and then weld the steel sheets to the steel rim. Because steel and aluminum have different thermal shrinkage ratios, the entire casting process becomes too complicated and costly, and also results in lower product quality and shorter service life. Utility Model Content
[0004] (I) This utility model provides a steel-aluminum wheel with edging, which alleviates the technical problem of low quality of steel-aluminum wheels 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 with rim, including a rim and spokes;
[0007] The spokes include a connecting portion connected to the rim. A connecting ring is welded to the rim flange. The connecting ring bends toward the spokes on the side away from the rim and covers the top edge of the connecting portion.
[0008] The end of the connecting part away from the connecting ring is riveted to the rim along the circumference of the wheel.
[0009] Furthermore, the bottom groove of the rim is provided with a protrusion along the circumference of the wheel, and the connecting part is provided with a groove that matches the protrusion, and the protrusion is fitted into the groove.
[0010] Furthermore, a positioning sleeve is provided in the groove, and the protrusion is fitted into the positioning sleeve.
[0011] Furthermore, the wheel has multiple protrusions, which are horizontally spaced along the circumference of the wheel, and the grooves correspond one-to-one with the protrusions.
[0012] Furthermore, the protrusions and the grooves are arc-shaped.
[0013] Furthermore, the diameter R of the protrusion and the groove is in the range of 6-12mm.
[0014] Furthermore, the diameters of the protrusions and the grooves are smaller than the width of the sealing ring of the rim.
[0015] Furthermore, the connecting ring can be integral or separate.
[0016] Furthermore, a sealing layer is provided at the steel-aluminum joint corresponding to the riveted connection between the spokes and the rim.
[0017] Furthermore, the sealing layer is formed by coating with sealant.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides a steel-aluminum wheel with edging, including a rim and spokes. The spokes have a connecting part, which is located between the spokes and the rim and is connected to the rim. A connecting ring is welded to the rim. The side of the connecting ring away from the rim is bent towards the spokes until it covers the top edge of the connecting part, thereby fixing the connecting ring to the spokes. This fixes the spokes and rim of different materials. Then, the end of the connecting part away from the connecting ring is riveted to the rim along the circumference of the wheel to limit the relative rotation of the spokes. The steel-aluminum wheel with edging produced by the above connection method does not require pre-embedded connecting parts in the spokes. Furthermore, the connecting ring covering the spokes and the riveting connection between the connecting part and the rim limit the detachment and relative rotation of the spokes and the rim, thereby improving product quality and effectively improving wheel performance and service life.

[0029] like Figure 1 As shown, this utility model provides a steel-aluminum wheel with edging, including a rim 100 and spokes 200; the spokes 200 include a connecting part 201, which is connected to the rim 100. A connecting ring 102 is welded to the rim 101 of the rim 100. The side of the connecting ring 102 away from the rim 100 is bent toward the spokes 200 and covers the edge of the top of the connecting part 201; the end of the connecting part 201 away from the connecting ring 102 is riveted to the rim 100 along the circumference of the wheel.
[0030] In this embodiment, the steel-aluminum wheel with edging includes a rim 100 and spokes 200. The spokes 200 have a connecting portion 201 located between the spokes 200 and the rim 100. The connecting portion 201 is connected to the rim 100. A connecting ring 102 is welded to the rim 100. The side of the connecting ring 102 away from the rim 100 is bent towards the spokes 200 until it covers the top edge of the connecting portion 201, thereby fixing the connecting ring 102 to the spokes 200, i.e., fixing the spokes 200 and rim 100 of different materials. The end of the connecting part 201 away from the connecting ring 102 is riveted to the rim 100 along the circumference of the wheel to limit the relative rotation of the spokes 200. The steel-aluminum wheels with edging produced by the above connection method do not need to have pre-embedded connecting parts in the spokes 200. Furthermore, the connecting ring 102 covers the spokes 200 and the riveting connection between the connecting part 201 and the rim 100 limits the separation and relative rotation of the spokes 200 and the rim 100, thereby improving the product quality and effectively improving wheel performance and extending wheel life.
[0031] According to one embodiment provided by this utility model, such as Figure 1 As shown, the bottom groove 103 of the rim 100 is provided with a protrusion 104 along the circumference of the wheel, and the connecting part 201 is provided with a groove 202 that matches the protrusion 104. The protrusion 104 is fitted into the groove 202.
[0032] In this embodiment, the end of the connecting part 201 facing away from the mounting groove is connected to the bottom groove 103 of the rim 100. A groove 202 is provided in the circumferential direction on the outer wall of the connecting part 201. A protrusion 104 adapted to the groove 202 is also provided in the circumferential direction on the bottom groove 103 of the rim 100. When the rim 100 and the spoke 200 are assembled, the protrusion 104 is assembled in the groove 202, thereby improving the load-bearing capacity and overall strength of the wheel. The assembly of the protrusion 104 and the groove 202 improves the connection between the rim 100 and the spoke 200 and prevents the spoke 200 from rotating in the circumferential direction of the rim 100.
[0033] The groove 202 is spherical, and the protrusion 104 is stamped in conjunction with the groove 202. The protrusion 104 is stamped from the bottom groove 103 of the rim 100.
[0034] According to one embodiment provided by this utility model, such as Figure 1 As shown, a positioning sleeve is provided in the groove 202, and the protrusion 104 is assembled into the positioning sleeve.
[0035] In this embodiment, the groove 202 is a countersunk hole, and a positioning sleeve is installed in the groove 202. The protrusion 104 is fitted to the positioning sleeve. By fitting the positioning sleeve, the wear of the wheel spoke 200 caused by the protrusion 104 can be effectively reduced, thereby affecting the use of the wheel and achieving the effect of improving the service life of the wheel.
[0036] Preferably, the positioning sleeve is made of steel, which improves its wear resistance.
[0037] According to one embodiment provided by this utility model, such as Figure 1 As shown, there are multiple protrusions 104, which are arranged horizontally at intervals along the circumference of the wheel, and the grooves 202 correspond one-to-one with the protrusions 104.
[0038] In this embodiment, multiple protrusions 104 are provided. Optionally, multiple protrusions 104 are arranged horizontally at intervals along the circumference of the wheel, or several protrusions 104 are grouped together to form a protrusion group 104. Multiple protrusion groups 104 are arranged horizontally at intervals along the circumference of the wheel. At the same time, the position and shape of the corresponding grooves 202 correspond one-to-one with the protrusions 104, so as to improve assembly efficiency and safety during assembly.
[0039] According to one embodiment provided by this utility model, such as Figure 1 As shown, the protrusion 104 and the groove 202 are arc-shaped.
[0040] In this embodiment, the outer surfaces of both the protrusion 104 and the groove 202 are arc-shaped to facilitate assembly. At the same time, the arc shape can ensure more uniform force distribution, further improving the load-bearing capacity and overall strength of the wheel.
[0041] According to one embodiment provided by this utility model, such as Figure 1 As shown, the diameter R of the protrusion 104 and the groove 202 is in the range of 6-12mm.
[0042] In this embodiment, the diameter R of the protrusion 104 and the groove 202 is within the range of 6-12mm. By using the protrusion 104 and the groove 202 within the above-mentioned diameter range, relative slippage between the two can be prevented during use, which can ensure the quality of the wheel and the safety of use. Optionally, the diameter can be 6mm, 8mm, 10mm or 12mm, etc., which can be set according to actual use requirements. Its purpose has not departed from the design concept of this utility model and should be within the protection scope of this utility model.
[0043] According to one embodiment provided by this utility model, such as Figure 1 As shown, the diameters of the protrusion 104 and the groove 202 are smaller than the width of the sealing ring of the rim 100.
[0044] In this embodiment, a combination drilling machine is first used to pre-fabricate grooves 202 on the aluminum spokes 200. Then, a combination riveting machine is used to rivet a portion of the rim 100 into the grooves 202 at the corresponding positions of the bottom grooves 103 of the rim 100, forming protrusions 104. This does not damage the original sealing surface of the rim 100, and the rim 100 remains a complete curved surface. Preferably, the diameters of the protrusions 104 and the grooves 202 are smaller than the width of the sealing ring of the rim 100, that is, the riveting diameter is smaller than the width of the sealing ring of the rim 100, so as not to affect the sealing performance of the rim 100.
[0045] According to one embodiment provided by this utility model, such as Figure 1 As shown, the connecting ring 102 can be a single piece or a separate piece.
[0046] In this embodiment, the connecting ring 102 is an integral piece. The connecting ring 102 is welded and fixed to the rim 101 of the wheel rim 100 by laser welding, and then bent towards the spoke 200 until it covers the top edge of the spoke 200, so as to fix the wheel rim 100 and spoke 200 of different materials together.
[0047] The connecting ring 102 can also be a split type. When the connecting ring 102 is a split type, each part of the connecting ring 102 is welded to the rim 101 of the rim 100 and then bent in the direction of the spoke 200. The principle is the same as described above, so it will not be described again.
[0048] According to one embodiment provided by this utility model, such as Figure 1 As shown, a sealing layer 300 is provided at the steel-aluminum joint corresponding to the riveted connection between the spokes 200 and the rim 100.
[0049] In this embodiment, in order to ensure the sealing of the spokes 200 and the rim 100 during riveting, a sealing layer 300 is provided at the steel-aluminum joint corresponding to the riveting connection to ensure that the sealing meets the usage requirements, thereby ensuring the quality of the wheel.
[0050] According to one embodiment provided by this utility model, such as Figure 1 As shown, the sealing layer 300 is made of sealant.
[0051] In this embodiment, preferably, the sealing layer 300 is formed by applying sealant at the corresponding location.
[0052] Optionally, the sealing layer 300 can also be formed by welding followed by grinding. This does not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.
[0053] 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.
