[0008] Furthermore, one end of the positioning column away from the stop end passes through the second positioning hole, and an external thread structure is formed on the outer wall surface of the positioning column. The positioning element also includes a fastening nut, which is threadedly connected to the positioning column and abuts against the axial outer surface of the spoke.

[0009] Furthermore, the positioning column includes a mounting rod body and a positioning plug, the positioning plug is protrudingly arranged on the end face of the mounting rod body, the mounting rod body is arranged through the second positioning hole, the positioning plug extends into the first positioning hole, and the end face of the mounting rod body provided with the positioning plug abuts against the rim.

Detailed Description of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] In order to solve the problem in the prior art that when a spoke is welded and installed on a rim, the coaxiality between the rim and the spoke cannot be guaranteed, the installation accuracy of the spoke is reduced, resulting in the spoke being unable to provide a stable and uniform supporting effect on the rim, causing uneven stress on the rim when the wheel is subjected to a radial load, and the rim having a large deformation amount, affecting the normal driving of the vehicle, and even threatening the life safety of the passengers, the present invention provides a wheel.

[0036] Embodiment 1

[0037] As Figure 1 and Figure 2 shown, the wheel includes a rim 10, a spoke 20 and a positioning element 30. Among them, a first positioning hole 11 is provided on the rim 10; the spoke 20 is arranged at one end of the rim 10 in the axial direction, and a second positioning hole 21 is provided at a position of the spoke 20 opposite to the first positioning hole 11; the positioning element 30 includes a positioning post 31, and the positioning post 31 is inserted into the first positioning hole 11 and the second positioning hole 21 to connect the spoke 20 and the rim 10.

[0038] This embodiment provides a wheel with a positioning element 30, ensuring the coaxiality between the welded spoke 20 and the rim 10.

[0039] Specifically, by optimizing the structural composition of the wheel, since the wheel includes a positioning element 30, in the process of installing the spoke 20 on the rim 10 before welding the spoke 20 and the rim 10, the operator can insert the positioning post 31 on the positioning element 30 into the first positioning hole 11 on the rim 10 and the second positioning hole 21 on the spoke 20, so as to accurately install and position the spoke 20 on the rim 10, lock the relative positions of the two, ensure that the two will not shift relative to each other during the subsequent welding operation, improve the installation accuracy of the spoke 20, ensure the coaxiality between the welded spoke 20 and the rim 10, enable the spoke 20 to provide a stable and uniform supporting effect on the rim 10, so as to ensure uniform stress on the rim 10 when the wheel is subjected to a radial load, avoid a large deformation amount of the rim 10, ensure the normal driving of the vehicle, and thus ensure the life safety of the passengers.

[0040] It should be noted that in this embodiment, the two end faces of the positioning post 31 are flush with the surfaces of the spoke 20 and the rim 10 respectively. In this way, it not only avoids the first end of the positioning post 31 protruding from the second positioning hole 21 on the spoke 20, but also ensures the overall aesthetic appearance of the wheel after the spoke 20 is installed and positioned on the rim 10; in addition, it also avoids the second end of the positioning post 31 protruding from the first positioning hole 11 on the rim 10, ensuring that the positioning post 31 does not occupy the installation space of the tire, thereby ensuring that the positioning post 31 will not cause wear to the tire and affect its service life.

[0041] As Figure 3 shown, the spoke 20 and the rim 10 are welded, and a first weld bead structure 40 and a second weld bead structure 50 are formed at the joint between the two. Among them, the first weld bead structure 40 is located between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and the second weld bead structure 50 is located between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21. In this way, by forming the first weld bead structure 40 between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and at the same time forming the second weld bead structure 50 between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21, the setting of the positioning element 30 can not only play a role in positioning the spoke 20, but also ensure that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the first weld bead structure 40 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and the second weld bead structure 50 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21, the welding area between the spoke 20 and the rim 10 is greatly increased, thereby ensuring the welding stability between the spoke 20 and the rim 10.

[0042] Embodiment Two

[0043] As Figure 4 shown, the positioning element 30 further includes a stop end 32. The stop end 32 is provided at one end of the positioning post 31, and a stop end face 33 is formed at the joint with the positioning post 31. The stop end face 33 is used to abut against the axial outer surface of the spoke 20. In this way, the setting of the stop end 32 ensures that after the spoke 20 is installed on the rim 10, the stop end face 33 of the stop end 32 abuts against the axial outer surface of the spoke 20, avoiding the positioning element 30 falling off from the first positioning hole 11 and the second positioning hole 21, and improving the positioning reliability of the spoke 20; in addition, when there are multiple positioning elements 30, the outer surfaces of the stop ends 32 on the multiple positioning elements 30 can be sprayed with pigments of different colors, which is beneficial to improving the aesthetic appearance of the wheel.

[0044] As Figure 5As shown, the spoke 20 is welded to the rim 10, and a third weld bead structure 60 is formed at the contact position between the stop end 32 and the spoke 20. In this way, by forming the first weld bead structure 40 between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and forming the third weld bead structure 60 at the contact position between the stop end 32 and the spoke 20, the positioning element 30 is fixedly installed on the wheel, preventing the positioning element 30 from falling off during vehicle driving. In addition, it ensures that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the first weld bead structure 40 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and at the same time the third weld bead structure 60 is formed at the contact position between the stop end 32 and the spoke 20, the welding area between the spoke 20 and the rim 10 is greatly increased, thus ensuring the welding stability between the spoke 20 and the rim 10.

[0045] Embodiment III

[0046] As Figure 6 shown, the difference between this embodiment and Embodiment II is that the rim 10 includes a rim body 12 and a bent flange 13. The bent flange 13 is connected to the periphery of one axial end of the rim body 12 and extends radially along the rim body 12 and then is connected to the inner axial surface of the spoke 20. The first positioning hole 11 is formed in the bent flange 13, and a stop step surface 111 is formed in the first positioning hole 11. The stop end 32 is located in the first positioning hole 11, and the stop end surface 33 abuts against the stop step surface 111. In this way, the stop end 32 is hidden in the first positioning hole 11, preventing the stop end 32 from protruding from the first positioning hole 11 on the rim 10 and occupying the installation space of the tire, which may cause air leakage after the tire is inflated. After the tire is installed on the wheel, it ensures that the tire has sufficient installation space, so as to ensure that the tire will not interfere with the stop end 32 due to the increase in the volume of the tire after inflation, and ensure that there is no air leakage after the tire is inflated.

[0047] It should be noted that in this embodiment, the end surface of the stop end 32 facing the rim 10 is flush with the outer surface of the bent flange 13. In this way, it prevents the stop end 32 from protruding from the first positioning hole 11 on the rim 10 and occupying the installation space of the tire. While ensuring that the tire has sufficient installation space, it can also ensure that the stop end 32 will not wear the tire and accelerate the aging of the tire, thus ensuring that the service life of the wheel can meet the expected design requirements.

[0048] As Figure 7As shown, the spoke 20 is welded to the rim 10, and a third weld bead structure 60 is formed at the contact position between the stop end 32 and the rim 10. In this way, by forming the second weld bead structure 50 between the outer wall surface of the positioning post 31 and the wall surface of the second positioning hole 21, and forming the third weld bead structure 60 at the contact position between the stop end 32 and the rim 10, the positioning element 30 is fixedly installed on the wheel, preventing the positioning element 30 from falling off during vehicle driving. In addition, it ensures that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the second weld bead structure 50 is formed between the outer wall surface of the positioning post 31 and the wall surface of the second positioning hole 21, and the third weld bead structure 60 is formed at the contact position between the stop end 32 and the rim 10, the welding area between the spoke 20 and the rim 10 is greatly increased, thus ensuring the welding stability between the spoke 20 and the rim 10.

[0049] Embodiment Four

[0050] As Figure 8 shown, the difference between this embodiment and Embodiment Three is that one end of the positioning post 31 away from the stop end 32 passes through the second positioning hole 21, and an external thread structure 314 is formed on the outer wall surface of the positioning post 31. The positioning element 30 further includes a fastening nut 34, and the fastening nut 34 is threadedly connected to the positioning post 31 and abuts against the axial outer surface of the spoke 20. In this way, through the threaded connection between the fastening nut 34 and the external thread structure 314 on the outer wall surface of the positioning post 31, the connection reliability between the spoke 20 and the rim 10 is ensured, so that during the subsequent welding process of the spoke 20 and the rim 10, no displacement occurs between the two, and thus the coaxiality between the spoke 20 and the rim 10 is ensured.

[0051] As Figure 9 shown, since the end face of the fastening nut 34 will be in close contact with the axial outer surface of the spoke 20 after being threadedly connected to the positioning post 31, in order to further improve the welding stability between the spoke 20 and the rim 10, as Figure 9 shown, a fourth weld bead structure 70 is formed at the contact position between the fastening nut 34 and the spoke 20. In this way, by forming the third weld bead structure 60 at the contact position between the stop end 32 and the rim 10, and forming the fourth weld bead structure 70 at the contact position between the fastening nut 34 and the spoke 20, the positioning element 30 is fixedly installed on the wheel, preventing the positioning element 30 from falling off during vehicle driving. In addition, it ensures that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the third weld bead structure 60 is formed at the contact position between the stop end 32 and the rim 10, and the fourth weld bead structure 70 is formed at the contact position between the fastening nut 34 and the spoke 20, the welding area between the spoke 20 and the rim 10 is greatly increased, thus ensuring the welding stability between the spoke 20 and the rim 10.

[0052] Embodiment Five

[0053] As Figure 10 shown, the difference between this embodiment and the first embodiment is that the positioning post 31 includes a mounting rod body 311 and a positioning plug 312. The positioning plug 312 is protrudingly provided on the end face of the mounting rod body 311. The mounting rod body 311 passes through the second positioning hole 21, and the positioning plug 312 extends into the first positioning hole 11. Moreover, the end face of the mounting rod body 311 where the positioning plug 312 is mounted abuts against the rim 10. In this way, after the spoke 20 is mounted on the rim 10, since the end face of the mounting rod body 311 where the positioning plug 312 is mounted abuts against the rim 10, it prevents the positioning post 31 from falling off from the first positioning hole 11 and the second positioning hole 21, improving the positioning reliability of the spoke 20. In addition, since the cross-sectional area of the positioning plug 312 is smaller than that of the mounting rod body 311, it prevents the first positioning hole 11 on the rim 10 from being too large and reducing the structural strength of the rim 10, thus ensuring the overall structural strength of the wheel.

[0054] As Figure 11 shown, the spoke 20 and the rim 10 are welded, and a first weld bead structure 40 and a second weld bead structure 50 are formed at the joint between the two. Among them, the first weld bead structure 40 is located between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and the second weld bead structure 50 is located between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21. In this way, by forming the first weld bead structure 40 between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and forming the second weld bead structure 50 between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21, the setting of the positioning element 30 can not only play a role in positioning the spoke 20, but also ensure that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the first weld bead structure 40 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and the second weld bead structure 50 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21, it greatly increases the welding area between the spoke 20 and the rim 10, thus ensuring the welding stability between the spoke 20 and the rim 10.

[0055] Embodiment Six

[0056] As Figure 12As shown, the difference between this embodiment and the second embodiment is that the positioning post 31 includes a mounting rod body 311 and a positioning plug 312. The positioning plug 312 is protrudingly provided on the end face of the mounting rod body 311. The mounting rod body 311 passes through the second positioning hole 21, and the positioning plug 312 extends into the first positioning hole 11. Moreover, the end face of the mounting rod body 311 where the positioning plug 312 is provided abuts against the rim 10. In this way, while the stop end face 33 of the stop end 32 abuts against the outer axial surface of the spoke 20, the end face of the mounting rod body 311 where the positioning plug 312 is mounted abuts against the rim 10, ensuring that the positioning element 30 will not fall off from the first positioning hole 11 and the second positioning hole 21, and at the same time, it can ensure that the spoke 20 provides a stable supporting effect on the rim 10, thereby avoiding a large deformation of the rim 10 when the wheel is subjected to a radial load and affecting the normal driving of the vehicle.

[0057] It should be noted that in this embodiment, the positioning plug 312 is located at one end of the positioning post 31 in the axial direction away from the stop end 32.

[0058] As Figure 13 As shown, the spoke 20 and the rim 10 are welded, and a third weld bead structure 60 is formed at the contact position between the stop end 32 and the spoke 20. In this way, by forming a first weld bead structure 40 between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and at the same time forming a third weld bead structure 60 at the contact position between the stop end 32 and the spoke 20, the positioning element 30 is fixedly installed on the wheel, preventing the positioning element 30 from falling off during vehicle driving. In addition, it ensures that the spoke 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the first weld bead structure 40 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the first positioning hole 11, and the third weld bead structure 60 is formed at the contact position between the stop end 32 and the spoke 20, the welding area between the spoke 20 and the rim 10 is greatly increased, thereby ensuring the welding stability between the spoke 20 and the rim 10.

[0059] Embodiment Seven

[0060] As Figure 14As shown, the difference between this embodiment and the first embodiment is that the rim 10 includes a rim body 12 and a bent flange 13. The bent flange 13 is connected to the periphery of one axial end of the rim body 12 and extends radially along the rim body 12 and then is connected to the axial inner surface of the wheel hub 20. An installation gap 100 is formed between the bent flange 13 and the wheel hub 20. The positioning post 31 further includes a support structure 313. The support structure 313 is wound around the outer wall surface of the positioning post 31 and fills the installation gap 100. In this way, the support structure 313 of the positioning post 31 fills the installation gap 100 formed between the bent flange 13 of the rim 10 and the wheel hub 20, ensuring that the wheel hub 20 can provide a stable and reliable supporting effect on the rim 10 through the support structure 313, thereby avoiding a large deformation of the rim 10 when the wheel is subjected to a radial load and ensuring that the wheel has sufficient radial load-bearing capacity.

[0061] As Figure 15 shown, the wheel hub 20 is welded to the rim 10, and a first weld bead structure 40 and a second weld bead structure 50 are formed at the connection between the two. Among them, the first weld bead structure 40 is located between the outer wall surface of the positioning post 31 and the wall surface of the first positioning hole 11, and the second weld bead structure 50 is located between the outer wall surface of the positioning post 31 and the wall surface of the second positioning hole 21. In this way, by forming the first weld bead structure 40 between the outer wall surface of the positioning post 31 and the wall surface of the first positioning hole 11, and at the same time forming the second weld bead structure 50 between the outer wall surface of the positioning post 31 and the wall surface of the second positioning hole 21, the setting of the positioning element 30 can not only play a role in positioning the wheel hub 20, but also ensure that the wheel hub 20 and the rim 10 are indirectly welded together through the positioning element 30. Since the first weld bead structure 40 is formed between the outer wall surface of the positioning post 31 and the wall surface of the first positioning hole 11, and the second weld bead structure 50 is formed between the outer wall surface of the positioning post 31 and the wall surface of the second positioning hole 21, the welding area between the wheel hub 20 and the rim 10 is greatly increased, thereby ensuring the welding stability between the wheel hub 20 and the rim 10.

It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0064] For the sake of convenience of description, spatial relative terms such as "above", "on top of", "on the upper surface", "upper" etc. may be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is inverted, the device described as "above" or "on top of" other devices or structures will then be positioned "below" or "beneath" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used here will be made.

[0065] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0066] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the present application described here can be implemented in an order different from those illustrated or described here.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
