The present application provides a wheel with positioning elements 30 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 positioning element 30 is arranged to comprise the connecting positioning column 31 and the connecting stop end 32, so that before the spoke 20 and the rim 10 are welded, in the process of mounting the spoke 20 on the rim 10, an operator can pass through the positioning column 31 on the positioning element 30 through the first positioning hole 13 and then extend into the second positioning hole 21, and the stop end 32 stops at the stop step surface 131, so that the positioning element 30 is prevented from falling out of the first positioning hole 13 and the second positioning hole 21, and the spoke 20 is accurately mounted and positioned on the rim 10, the relative positions of the spoke 20 and the rim are locked, the relative displacement between the spoke 20 and the rim 10 cannot occur in the later welding operation, the mounting precision of the spoke 20 is improved, and the coaxiality between the welded spoke 20 and the rim 10 is ensured.

As shown in fig. 2, the first positioning hole 13 includes a stop hole section 132 and a guide hole section 133 communicating with each other along a direction away from the rim body 11, a stop step surface 131 is formed at a junction of the stop hole section 132 and the guide hole section 133, a stop end surface 321 is formed at a junction of the stop tip 32 and the positioning pillar 31, and the stop end surface 321 abuts against the stop step surface 131. In this way, the first positioning hole 13 is configured to include the stop hole section 132 and the guide hole section 133, and the stop step surface 131 formed at the junction of the two sections plays a role of stopping and limiting the positioning element 30, so that after the spoke 20 is mounted and positioned on the rim 10, the positioning element 30 is prevented from falling from the first positioning hole 13 and the second positioning hole 21, and the mounting accuracy of the spoke 20 is ensured.

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 first 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.

Optionally, the stop tip 32 is located within the stop bore segment 132. Thus, the stop end 32 of the positioning element 30 is hidden in the first positioning hole 13, the situation that the tire installation space is occupied because the stop end 32 extends out of the first positioning hole 13 on the rim 10 is avoided, the stop end 32 of the positioning element 30 cannot interfere with the tire with the increased volume after inflation, the air leakage phenomenon cannot occur after inflation of the tire is ensured, and the normal running of the vehicle is ensured.

In this way, it is ensured that the second bead structure 200 can fill the gap at the joint of the spoke 20 and the rim 10 as much as possible, thereby ensuring the welding reliability therebetween, and further, the provision of the second bead structure 200 ensures that the spoke 20 and the rim 10 are welded together indirectly through the positioning element 30, and since the second bead structure 200 is formed between the outer wall surface of the positioning post 31 and the hole wall surface of the second positioning hole 21 and the hole wall surface of a part of the first positioning hole 13, the welding area between the spoke 20 and the rim 10 is greatly increased, thereby ensuring the welding stability of the spoke 20 and the rim 10.
