As shown in fig. 1 and 2, the wheel includes a rim 10, a spoke 20, a positioning member 30 and a fastener 40, wherein the rim 10 includes a rim body 11 and a bent flange 12, and the bent flange 12 is connected with a circumferential edge of one axial end of the rim body 11 and extends in a bent manner; the spoke 20 is arranged at one axial end of the rim 10, the axial inner surface of the spoke 20 is in adaptive fit with the axial first end surface of the bent flanging 12, and a first positioning hole 21 is formed in the spoke 20; the first end of the positioning element 30 is connected with the bending flange 12, and the second end of the positioning element 30 passes through the first positioning hole 21 and then is connected with the fastener 40 to fasten and connect the rim 10 and the spoke 20.

The present application provides a wheel with positioning elements 30 and fasteners 40 ensuring coaxiality between the welded spoke 20 and rim 10 and optimizing the connection position of the spoke 20 to the rim 10, ensuring a reliable radial load-bearing capacity of the wheel.

Specifically, by optimizing the structural composition of the wheel, the wheel comprises the positioning element 30 and the fastening piece 40, so that in the process of mounting the spoke 20 on the rim 10 before welding the spoke 20 and the rim 10, because the first end of the positioning element 30 is connected with the bent flanging 12, an operator only needs to pass the second end of the positioning element 30 through the first positioning hole 21 and then connect the second end of the positioning element 30 with the fastening piece 40, so that the spoke 20 is accurately mounted and positioned on the rim 10, and the spoke 20 and the rim 10 are tightly connected through the positioning element 30 and the fastening piece 40, so that the relative position displacement of the spoke 20 and the rim 10 in the subsequent welding operation process is effectively avoided, the mounting precision of the spoke 20 is improved, and the coaxiality between the welded spoke 20 and the rim 10 is ensured.

In addition, through optimizing the connecting position of spoke 20 and rim 10, make the axial internal surface of spoke 20 and the first terminal surface suitability laminating of the axial of the turn-ups 12 of bending of rim 10, the axial internal surface of spoke 20 directly laminates with the surface suitability of turn-ups 12 of bending promptly, increased area of contact between the two, ensure that spoke 20 can provide reliable and stable supporting effect for rim 10, thereby ensure that the wheel possesses reliable radial bearing capacity, like this, when the vehicle receives radial load effect, rim 10 can not produce great deformation and influence the normal driving of vehicle, thereby guarantee passenger's life safety.

As shown in fig. 2 to 5, a second positioning hole 13 is formed at a position of the bent flange 12 opposite to the first positioning hole 21, a stopping step surface 131 is formed in the second positioning hole 13, and the positioning element 30 includes a positioning post 31 and a stopping end head 32 connected to each other, wherein the stopping end head 32 stops at the stopping step surface 131, and the positioning post 31 extends out of the second positioning hole 13 and then passes through the first positioning hole 21 to be connected to the fastening member 40. Thus, after the positioning element 30 sequentially passes through the second positioning hole 13 and the first positioning hole 21, the stop end 32 is ensured to stop at the stop step surface 131, and the positioning element 30 is prevented from falling off from one side of the first positioning hole 21 far away from the rim 10 and being incapable of positioning the spoke 20, so that the mounting accuracy of the spoke 20 is ensured.

As shown in fig. 2, the bending flange 12 includes a radial ring plate section 121, a transition ring plate section 122 and an axial ring plate section 123 connected in sequence along a direction away from the rim body 11, wherein the second positioning hole 13 is opened on the radial ring plate section 121, the transition ring plate section 122 extends in a curved shape, and the axial inner surface of the spoke 20 is simultaneously attached to the surface of the radial ring plate section 121 and the surface of the transition ring plate section 122 in a fitting manner. Thus, when the wheel is subjected to radial load, the transition ring plate section 122 of the bent flange 12 is most easily deformed, and the axial inner surface of the spoke 20 is simultaneously attached to the surface of the radial ring plate section 121 and the surface of the transition ring plate section 122 in a fitting manner, so that the contact area between the spoke 20 and the rim 10 is ensured to be large enough, the spoke 20 can be ensured to simultaneously provide stable and reliable supporting function for the radial ring plate section 121 and the transition ring plate section 122, the structural strength of the rim 10 is prevented from being influenced due to the large deformation of the transition ring plate section 122, and the vehicle can normally run.

As shown in fig. 2, an end face of the stop tip 32 that is away from the positioning column 31 is flush with an axial second end face of the bent flange 12. Thus, the phenomenon of air leakage after the tire is inflated due to the fact that the stop end head 32 extends out of the second positioning hole 13 in the rim 10 to occupy the installation space of the tire is avoided, and after the tire is installed on a wheel, the tire is ensured to have enough installation space, so that interference with the stop end head 32 due to the fact that the size of the tire is increased after the tire is inflated is avoided, and the phenomenon of air leakage after the tire is inflated is ensured.

As shown in fig. 2-5, the axial ring plate segments 123 project from the axially outer surface of the spokes 20. Thus, on the premise of ensuring that the axial inner surface of the spoke 20 is simultaneously attached to the surface of the radial ring plate section 121 and the surface of the transition ring plate section 122 in a matching manner, the spoke 20 is designed to be light and thin, and the light-weight design of the wheel is facilitated.

In the present application, the end surface of the axial ring plate section 123 far from the transition ring plate section 122 is a smooth curved surface. In this way, the end face of the axial ring plate section 123 far away from the transition ring plate section 122 is ensured to be matched with the inner wall surface of the tire, and the tire is prevented from being worn due to the protrusion of the end face of the axial ring plate section 123 far away from the transition ring plate section 122.

In an embodiment of the application, which is not shown in the drawings, the first end of the positioning element 30 is welded to the end face of the bent flange 12 facing the spoke 20; in this way, the positioning element 30 is firmly connected to the bent flange 12, ensuring that the spoke 20 can be accurately mounted and positioned on the rim 10 with only one positioning operation when the spoke 20 is mounted on the rim 10.
