DETAILED DESCRIPTION

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0045] References to "one embodiment" or "example" or "example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0046] In order to solve the above technical problems, as one aspect of the present invention, a wheel is provided, such as Figures 1 to 6 , Figure 8 , Fig.21 As shown, the wheel includes an outer spoke 100, an inner spoke 200 and a rim 300. The outer spoke 100 and the inner spoke 200 are fixedly connected to the inner wall of the rim 300 in sequence along the axial direction of the rim 300. The outer spoke 100 has a plurality of mounting through holes 101, and the inner spoke 200 has a plurality of connecting through holes 201. The positions of the plurality of connecting through holes 201 and the plurality of mounting through holes 101 correspond one to one. The outer spoke 100 and the inner spoke 200 are fixedly connected at the connecting through holes 201 and the corresponding mounting through holes.

[0047] In the wheel provided by the present invention, the wheel hub spoke part adopts a double-layer structure composed of an outer wheel spoke 100 and an inner wheel spoke 200, and the corresponding connecting through holes 201 are connected to the mounting through holes 101, and form a space for the installation fasteners (for example, mounting screws) to pass through. When the wheel is fixedly connected to the axle, the mounting fasteners pass through the space and are fixed on the axle. When the vehicle is turning, the torque transmitted from the axle first acts on the connection between the connecting through hole 201 and the corresponding mounting through hole 101, and then applies a force to the outer wheel spoke 100 and the inner wheel spoke 200, thereby driving the outer rim 300 to rotate. In this process, the connection between the connecting through hole 201 and the mounting through hole 101 applies a force mainly in the radial direction to the outer wheel spoke 100 and the inner wheel spoke 200, respectively, so that the thin-walled outer wheel spoke 100 and the inner wheel spoke 200 do not need to bear too much torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0048] For example, Fig. 20 As shown, when the vehicle turns left, the wheel axle applies torque to the wheel under the action of the bending moment T, and at this time, the outer spoke 100 applies a radially forward force F1 to the rim 300, and the inner spoke 200 applies a radially backward force F2 to the rim 300, thereby driving the wheel rim 300 to rotate. In the present invention, the outer spoke 100 and the inner spoke 200 are axially distributed, so that when the wheel is twisted, the force borne by each single spoke component (outer spoke 100, inner spoke 200) is mainly in the radial direction, and a large lateral torque will not be generated on a single spoke component, thereby ensuring the lateral stiffness of the wheel, ensuring that the wheel can withstand the torque acting on the wheel when the vehicle turns, and extending the service life of the wheel.

[0049] Furthermore, the outer spoke 100 and the inner spoke 200 are spaced apart in the axial direction with a cavity structure therebetween, thereby reducing the material of the wheel hub spokes and the total weight of the wheel while reducing bending and torsional stress, thereby reducing the material cost of the wheel and facilitating lightweighting of the vehicle.

[0050] It should be pointed out that although it is described above that "the outer spoke 100 and the inner spoke 200 are fixedly connected at the connecting through hole 201 and the corresponding mounting through hole 101", the wheel does not have through holes only at the connecting through hole 201 and the mounting through hole 101, but also has fixed connections at other positions (for example, the outer spoke, the inner spoke, and the edge of the rim).

[0051] As an optional embodiment of the present invention, the outer spoke 100 is made of aluminum or aluminum alloy.

[0052] As an optional embodiment of the present invention, the wall thickness of the outer spoke 100 is 0.05 mm to 0.15 mm.

[0053] As an optional embodiment of the present invention, the wall thickness of the outer spoke 100 is 0.1 mm.

[0054] As an optional embodiment of the present invention, the inner spoke 200 is made of aluminum or aluminum alloy.

[0055] As an optional embodiment of the present invention, the wall thickness of the inner spoke 200 is 0.05 mm to 0.15 mm.

[0056] As an optional embodiment of the present invention, the wall thickness of the inner spoke 200 is 0.1 mm.

[0057] As an optional embodiment of the present invention, the material of the rim 300 is steel.

[0058] As an optional embodiment of the present invention, the wall thickness of the rim 300 is 0.05 mm to 0.15 mm.

[0059] As an optional embodiment of the present invention, the wall thickness of the rim 300 is 0.1 mm.

[0060] As an optional embodiment of the present invention, Figure 3 As shown, a plurality of mounting through holes 101 are distributed at intervals around the axis of the rim 300 , and a plurality of connecting through holes 201 are distributed at intervals around the axis of the rim 300 .

[0061] As an optional embodiment of the present invention, Figure 3 As shown, a plurality of mounting through holes 101 are distributed at equal intervals around the axis of the rim 300 , and a plurality of connecting through holes 201 are distributed at equal intervals around the axis of the rim 300 .

[0062] In the embodiment of the present invention, the plurality of connecting through holes 201 are evenly distributed in the circumferential direction to ensure that the hub spokes are subjected to loads evenly in the circumferential direction, thereby further ensuring the service life of the wheel.

[0063] As an optional embodiment of the present invention, Figure 3 As shown, the diameter d1 of the concentric circles of the plurality of mounting through holes 101 distributed around the axis of the rim 300 is 80 mm to 120 mm.

[0064] As an optional embodiment of the present invention, Figure 3 As shown, the diameter d1 of the concentric circles of the plurality of mounting through holes 101 distributed around the axis of the rim 300 is 100 mm.

[0065] In the embodiment of the present invention, there is no particular limitation on how to fix the connection between the connecting through hole 201 and the corresponding mounting through hole 101. As an optional implementation, Figure 1As shown, the wheel includes a plurality of connecting sleeves 400 , which are fixedly disposed between the outer spoke 100 and the inner spoke 200 , and the first end of the connecting sleeve 400 is connected to the mounting through hole 101 , and the second end of the connecting sleeve 400 is connected to the corresponding connecting through hole 201 .

[0066] Specifically, a plurality of connecting sleeves 400 are provided at the position where the wheel axle needs to be connected by installing fasteners (i.e., the central hub portion 210), and the two ends of the connecting sleeve 400 are respectively connected to the outer spoke 100 and the inner spoke 200, so that when the vehicle turns, the torque transmitted from the wheel axle first acts on the connecting sleeve 400, and then applies a force to the outer spoke 100 and the inner spoke 200 through the sleeve, thereby driving the outer rim 300 to rotate. During this process, the sleeve applies a force mainly in the radial direction to the outer spoke 100 and the inner spoke 200, so that the thin-walled outer spoke 100 and the inner spoke 200 do not need to bear too much torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0067] In the embodiment of the present invention, there is no particular limitation on the specific number of the mounting through hole 101, the connecting through hole 201, and the connecting sleeve. Figure 3 As shown, the wheel includes four connecting sleeves 400 , four mounting through holes 101 , and four connecting through holes 201 .

[0068] In the embodiment of the present invention, the structure of the connecting sleeve 400 is not particularly limited, as long as it can fix the outer spoke 100 and the inner spoke 200 and will not fall out of the mounting through hole 101 and the connecting through hole 201. For example, the connecting sleeve 400 can be a tubular member, and the connecting sleeve 400 is fixed in the mounting through hole 101 and the connecting through hole 201 by interference fit.

[0069] As an optional embodiment of the present invention, Figure 2 and Fig.12 As shown, the connecting sleeve 400 includes a sleeve body 403 and a first positioning boss 401. The first positioning boss 401 is arranged on the outer surface of the sleeve body 403 and is located at the first end of the connecting sleeve 400. It should be noted that the first positioning boss 401 protrudes radially from the outer edge of the mounting through hole 101.

[0070] The first positioning boss 401 abuts against the outer spoke 100 at the outer side of the outer spoke 100 (the side away from the inner spoke 200 ), or the first positioning boss 401 abuts against the outer spoke 100 at the inner side of the outer spoke 100 (the side facing the inner spoke 200 ).

[0071] The following describes an implementation method in which the first positioning boss 401 abuts against the outer spoke 100 on the outer side of the outer spoke 100. The orientation of the positioning end face α of the first positioning boss 401 is the same as the orientation of the end face of the first end of the connecting sleeve 400 (also the end face of the sleeve body 403). When the connecting sleeve 400 is assembled with the outer spoke 100, the connecting sleeve 400 is inserted into the corresponding mounting through hole 101 from the inner side of the outer spoke 100 until the positioning end face α of the first positioning boss 401 abuts against the inner surface of the outer spoke 100.

[0072] In the embodiment of the present invention, the size and arrangement of the first positioning boss 401 are not particularly limited, as long as the positioning boss 401 can prevent the connecting sleeve 400 from escaping from the mounting through hole 101. As an optional embodiment, the first positioning boss 401 is arranged around the sleeve body 403.

[0073] Similarly, in order to prevent the connecting sleeve 400 from being disengaged from the connecting through hole 201 of the inner spoke 200, optionally, as Figure 4 , Fig.12 As shown, the second end of the connecting sleeve 400 may be provided with a second positioning boss 402. That is, the outer surface of the sleeve body 403 is provided with the second positioning boss 402, and the second positioning boss 402 protrudes radially from the outer edge of the connecting through hole 201.

[0074] The second positioning boss 402 abuts against the inner spoke 200 at the outer side of the inner spoke 200 (the side away from the outer spoke 100 ), or the second positioning boss 402 abuts against the inner spoke 200 at the inner side of the inner spoke 200 (the side facing the outer spoke 100 ).

[0075] The following describes an implementation method in which the second positioning boss 402 abuts against the inner spoke 200 on the outer side of the inner spoke 200. The orientation of the positioning end face β of the second positioning boss is consistent with the orientation of the end face of the second end of the connecting sleeve 400 (i.e., the end face of the second end of the sleeve body 403). The second end of the connecting sleeve 400 passes through the connecting through hole 201, and the inner spoke 200 is folded inwardly at the edge area of ​​the connecting through hole 201 and abuts against the positioning end face β of the second positioning boss 402.

[0076] When assembling the connecting sleeve 400 with the inner spoke 200 , the connecting sleeve 400 is inserted into the corresponding connecting through hole 201 from the inner side of the inner spoke 200 until the positioning end surface β of the second positioning boss 402 abuts against the inner surface of the inner spoke 200 .

[0077] In the embodiment of the present invention, the specific structure and setting method of the second positioning boss 402 are not particularly limited, as long as the connecting sleeve 400 can be prevented from passing through the connecting through hole 201. Optionally, the second positioning boss 402 is arranged around the sleeve body 403. That is to say, the second positioning boss 402 has a positioning end face β surrounding the outer side of the second end face of the connecting sleeve 400, the second end of the connecting sleeve 400 passes through the connecting through hole 201, and the inner spoke 200 is concave inward (in the embodiment of the present invention, the inner side of the outer spoke 100 and the inner spoke 200 refers to the side of the cavity between the outer spoke 100 and the inner spoke 200, and the outer side of the outer spoke 100 and the inner spoke 200 refers to the side away from each other) at the edge area of ​​the connecting through hole 201 and abuts against the positioning end face β.

[0078] In the embodiment of the present invention, the first end of the connecting sleeve 400 enters the mounting through hole 101, thereby cooperating with the inner wall of the mounting through hole 101 to achieve radial positioning, and achieves axial positioning by abutting the inner wall of the outer spoke 100 through the positioning end face α, and the positioning end face β of the second end serves as a positioning surface in the rotary riveting process. The material of the inner spoke 200 around the connecting through hole 201 is folded inward during the rotary riveting process to ensure that the second end of the connecting sleeve 400 is stably fixed, thereby ensuring the connection strength between the connecting sleeve 400 and the outer spoke 100 and the inner spoke 200.

[0079] In the embodiment of the present invention, the connecting sleeve 400 may include a sleeve body 403 , a first positioning boss 401 disposed on an outer surface of a first end of the sleeve body 403 , and a second positioning boss 402 disposed on an outer surface of a second end of the sleeve body 403 .

[0080] As an optional embodiment of the present invention, Fig.12 As shown, the inner hole of the connecting sleeve 400 includes a mounting section 410 extending to the first end of the connecting sleeve 400 and a connecting section 420 extending to the second end of the connecting sleeve 400, the cross-sectional dimension of the mounting section 410 is larger than the cross-sectional dimension of the connecting section 420, and the inner hole of the connecting sleeve 400 has a fastening step surface facing the first end of the connecting sleeve 400 between the mounting section 410 and the connecting section 420, and the fastening step surface is used to cooperate with the head of a threaded fastener (e.g., a screw or a bolt).

[0081] In order to facilitate the fastener to enter the connecting section 420 from the installation section 410, as an optional embodiment of the present invention, Fig.12As shown, the inner hole of the connecting sleeve 400 also includes a guide section 430 connected between the mounting section 410 and the connecting section 420, and the cross-sectional dimension of the end portion of the guide section 430 toward the second end of the connecting sleeve 400 corresponds to the cross-sectional dimension of the connecting section 420, and the cross-sectional dimension of the guide section 430 gradually increases in the direction toward the first end of the connecting sleeve 400, and the fastening step surface is located at the connection between the mounting section 410 and the guide section 430.

[0082] As an optional embodiment of the present invention, Figure 4 As shown, the diameter d2 of the connecting section 420 is 12 mm to 16 mm.

[0083] As an optional embodiment of the present invention, the diameter d2 of the connecting section 420 is 14 mm.

[0084] As an optional embodiment of the present invention, Fig.12 As shown, the outer side surface of the first end of the connecting sleeve 400 has an annular outer boss 440 extending around the axis of the connecting sleeve 400 , and the surface of the annular outer boss 440 facing the first end of the connecting sleeve 400 is formed as a first positioning step surface α.

[0085] As an optional embodiment of the present invention, Fig.12 As shown, the second end of the connecting sleeve 400 has an annular positioning groove 450 extending around the axis of the connecting sleeve 400, and the bottom surface of the annular positioning groove 450 is formed as a second positioning step surface β.

[0086] As another optional embodiment of the present invention, the two ends of the connecting sleeve 400 can also be directly fixedly connected to the inner spoke 200 and the outer spoke 100. Specifically, as Figure 1 As shown, the first end of the connecting sleeve 400 passes through the mounting through hole 101 , and is fixedly connected to the outer spoke 100 ; the second end of the connecting sleeve 400 passes through the connecting through hole 201 , and is fixedly connected to the inner spoke 200 .

[0087] In the embodiment of the present invention, there is no special limitation on how to achieve the above-mentioned "fixed connection". For example, the "fixed connection" is welding.

[0088] It should be noted that the outer spoke 100 and the inner spoke 200 can be fixedly connected without the connection sleeve 400. For example, the outer spoke 100 and the inner spoke 200 can be fixedly connected at the installation through hole 101 and the connection through hole 201 by riveting, flanging, etc.

[0089] Optionally, the inner edge of one of the connecting through hole 201 and the corresponding mounting through hole 101 protrudes toward the other of the connecting through hole 201 and the corresponding mounting through hole 101 so that the outer spoke 100 and the inner spoke 200 are connected through the connecting through hole 201 and the mounting through hole 101.

[0090] In the embodiment shown in the figure, the inner edge of the connecting through hole 201 protrudes toward the mounting through hole 101 .

[0091] It should be noted that an inner center hole 202 is formed at least in the middle of the inner spoke 200 for the wheel axle to be inserted into the inner center hole 202 .

[0092] In order to further improve the lateral stiffness of the wheel, as an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, the wheel also includes a lateral reinforcement 500, an inner center hole 202 is formed in the middle of the inner spoke 200, a plurality of connecting through holes 201 are distributed around the inner center hole 202, the lateral reinforcement 500 is arranged in the inner center hole 202, and an axle opening is formed at one end of the lateral reinforcement 500 facing the rim 300 for the axle to be inserted.

[0128] As a second aspect of the present invention, a method for manufacturing a wheel is provided, which is used to manufacture a front wheel. The method for manufacturing the wheel comprises:

[0129] Step S1, providing an outer spoke, an inner spoke and a rim, wherein the outer spoke has a plurality of mounting through holes, the inner spoke has a plurality of connecting through holes, and the plurality of connecting through holes correspond to the plurality of mounting through holes in one-to-one position;

[0130] Step S2, fixing and connecting the outer spoke and the inner spoke at a plurality of connecting through holes and mounting through holes;

[0131] Step S3, respectively fixing the outer spoke and the inner spoke to the inner wall of the rim, so that the outer spoke and the inner spoke are fixedly connected to the inner wall of the rim in sequence along the axial direction of the rim.

When the wheel is fixedly connected to the axle, the mounting fasteners pass through the space and are fixed on the axle. When the vehicle is turning, the torque transmitted from the axle first acts on the connection between the connecting through hole 201 and the corresponding mounting through hole 101, and then applies a force to the outer spoke 100 and the inner spoke 200, thereby driving the outer rim 300 to rotate. In this process, the connection between the connecting through hole 201 and the mounting through hole 101 applies a force mainly in the radial direction to the outer spoke 100 and the inner spoke 200, respectively, so that the thin-walled outer spoke 100 and the inner spoke 200 do not need to bear too much torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0133] Furthermore, the outer spoke 100 and the inner spoke 200 are spaced apart in the axial direction with a cavity structure therebetween, thereby reducing the material of the wheel hub spokes and the total weight of the wheel while reducing bending and torsional stress, thereby reducing the material cost of the wheel and facilitating lightweighting of the vehicle.

[0134] As an optional embodiment of the present invention, the outer spokes and the inner spokes may be fixedly connected by connecting sleeves 400. Accordingly, step S2 may include: assembling the first ends of the connecting sleeves 400 with the corresponding mounting through holes, and assembling the second ends of the connecting sleeves 400 with the corresponding connecting through holes, so as to achieve fixed connection between the outer spokes and the inner spokes.

[0135] As an optional embodiment, a first positioning boss 401 having a positioning end surface α is formed at the first end of the connecting sleeve 400, and a second positioning boss 402 having a positioning end surface β is formed at the second end of the connecting sleeve 400;

[0136] In step S2, the mounting through hole of the outer spoke is assembled with the first end of the corresponding connecting sleeve, and the connecting through hole of the inner spoke is assembled with the second end of the corresponding connecting sleeve, so as to achieve a fixed connection between the outer spoke and the inner spoke:

[0137] Step S21, passing the first end of the connecting sleeve 400 through the mounting through hole 101, and making the positioning end surface α abut against the inner wall of the outer spoke 100;

[0138] Step S22 , rotating and pressing the portion of the inner spoke 200 corresponding to the edge area of ​​the connecting through hole 201 (ie, performing a rotary riveting process) so that the inner spoke 200 is folded inward at the edge area of ​​the connecting through hole 201 and abuts against the positioning end surface β.

[0139] As an optional embodiment of the present invention, step S22 is specifically implemented by a rotary riveting process. Specifically, rotating and pressing the portion of the inner spoke 200 corresponding to the edge area of ​​the connecting through hole 201 may specifically include:

[0140] The inner spoke 200 corresponding to the edge area of ​​the connecting through hole 201 is pressed toward the positioning end surface β by an annular pressing tool 10 corresponding to the shape of the positioning end surface β, and the annular pressing tool is driven to rotate around the axis of the connecting sleeve 400 (such as Fig.14 as shown).

[0141] As another optional implementation of the present invention, step S22 may also be implemented by other processes, specifically, as Fig.15 As shown, the portion of the inner spoke 200 corresponding to the edge area of ​​the connecting through hole 201 can also be gradually pressed inward by a non-cylindrical side pressing tool 20 .

[0142] As an optional implementation of the present invention, step S2 further includes:

[0143] Step S23, cutting off the portion of the connecting sleeve 400 exposed outside the connecting through hole 201 (such as Fig.16 as shown).

[0144] That is, a certain margin is left at the end of the connecting sleeve 400 before the riveting process, which can play a guiding role when the material of the inner spoke 200 is curled, and the excess material can be cut off after the riveting process is completed.

[0145] As another optional implementation of the present invention, step S2 may specifically include:

[0146] Step S23, passing the first end of the connecting sleeve 400 through the mounting through hole 101, and passing the second end of the connecting sleeve 400 through the connecting through hole 201;

[0147] Step S24 , welding the first end of the connecting sleeve 400 to the outer spoke 100 , and welding the second end of the connecting sleeve 400 to the inner spoke 200 .

[0152] Specifically, the roll forming process includes three rolling steps, and / or the roll forming process includes spinning, expansion, and finishing.

[0153] In the embodiment of the present invention, the rim blank can be formed by using the sheet material. Specifically, the sheet material can be processed into the rim blank through the steps of rolling, flattening, butt welding, and removing welding slag.

[0154] In the embodiment of the present invention, there is no particular limitation on how to provide the outer spokes and the inner spokes. For example, the outer spokes and the inner spokes can be formed by hot forming or cold forming.

[0158] In the wheel provided by the present invention, the hub spoke part adopts a double-layer structure composed of an outer spoke 100 and an inner spoke 200. When the wheel is fixedly connected to the axle, the fastener is installed to pass through the space and fixed on the axle. When the vehicle is turning, the torque transmitted from the axle first acts on the lateral reinforcement 500, and then applies a force to the outer spoke 100 and the inner spoke 200, thereby driving the outer rim 300 to rotate. In this process, the lateral reinforcement 500 applies a force mainly in the radial direction to the outer spoke 100 and the inner spoke 200, respectively, so that the thin-walled outer spoke 100 and the inner spoke 200 do not need to bear too much torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0159] Furthermore, the outer spoke 100 and the inner spoke 200 are spaced apart in the axial direction with a cavity structure therebetween, thereby reducing the material of the wheel hub spokes and the total weight of the wheel while reducing bending and torsional stress, thereby reducing the material cost of the wheel and facilitating lightweighting of the vehicle.

[0160] In the embodiment of the present invention, there is no particular limitation on the specific structure of the lateral reinforcement member 500. For example, the lateral reinforcement member 500 may have a tubular structure or a cylindrical structure with a bottom cover. It should be noted that when the lateral reinforcement member 500 is a cylindrical structure with a bottom cover, no through hole is provided at a position on the outer spoke 100 opposite to the lateral reinforcement member 500, and the bottom cover of the lateral reinforcement member 500 faces the outer spoke 100.
