By optimizing the welding position of the rim 10 and the spoke 20, the axial inner side surface at the outer periphery of the spoke 20 is welded with the inner wall surface of the transition ring plate section 122 of the rim 10 at the rim edge, so that after the spoke 20 is fixedly connected with the rim 10, the connection stability of the spoke 20 and the rim 10 is ensured, the spoke 20 is positioned at one axial end of the rim 10, the spoke 20 is ensured not to occupy too much space at the axial inner side of the rim 10, thereby reserving enough installation space for a braking mechanism of a vehicle, ensuring that the braking mechanism has enough large heat dissipation space after being installed, ensuring that heat generated in the braking process of the braking mechanism can be timely dispersed, avoiding accelerating the aging of the tire due to the temperature rise of the tire caused by heat accumulation, effectively prolonging the service life of the tire, avoiding serious accidents such as ignition or tire burst and the like, and ensuring that the vehicle can normally run, the life safety of the user is guaranteed.

In the present application, the mounting space surrounded by the mounting ring plate 11 is used for mounting the above-described brake mechanism.

As shown in fig. 1 and 4, the spoke 20 includes a central mounting plate 21 and a plurality of spokes 22, wherein the spokes 22 are radially spaced around the circumference of the central mounting plate 21, a vent hole 23 is formed between two adjacent spokes 22, a first end of each spoke 22 is connected to the central mounting plate 21, and a second end of each spoke 22 is welded to the inner wall surface of the rim 10. Thus, the spoke 20 with the structure effectively reduces the processing and manufacturing difficulty of the spoke 20 and improves the economy of the wheel; in addition, the arrangement of the vent holes 23 ensures that heat generated by a braking mechanism of the vehicle in the braking process can be timely dispersed, and the phenomenon that the tire is ignited or blown out due to the fact that the tire is in a high-temperature state for a long time in the driving process of the vehicle is avoided.

Optionally, the surface of the transition ring plate section 122 facing the spoke 20 is a first curved surface connecting surface, and a second curved surface connecting surface adapted to fit the first curved surface connecting surface is formed at a position opposite to the first curved surface connecting surface on the axially inner side surface of the spoke 22. In this way, the spoke 20 is welded to the first curved surface connecting surface on the transition ring plate section 122 of the rim 10 through the second curved surface connecting surface, so that the welding area between the spoke and the first curved surface connecting surface is increased, and the stability of the welding position between the spoke and the first curved surface connecting surface is ensured.

As shown in fig. 2 and 3, the first ring plate segment 121 extends in the axial direction of the rim 10, and the second ring plate segment 123 extends in the radial direction of the rim 10 by a predetermined distance and then curves to the axial direction of the rim 10; the spoke 22 includes a spoke body 221, a first radial plate body 222, a transition plate body 223 and a second radial plate body 224 which are connected in sequence, wherein a second curved surface connecting surface is formed on the transition plate body 223, and the second radial plate body 224 extends along the radial direction of the rim 10 and is attached to the second ring plate section 123.

Thus, the provision of the first structural reinforcing grooves 225 increases the structural strength of the spokes 22 without changing the flow area of the vent holes 23, while the provision of the second structural reinforcing grooves 213 ensures that the central mounting plate 21 has sufficient strength, thereby increasing the overall structural strength of the spokes 20; further, the center via hole 211 is provided for wheel-to-axle connection, and the plurality of mounting holes 212 are provided for fastening mounting of the wheel to the axle.

Alternatively, the width of the first structural reinforcement groove 225 is gradually reduced in a direction away from the central mounting plate 21, and the depth of the first structural reinforcement groove 225 is gradually reduced in a direction away from the central mounting plate 21. Thus, the first structural reinforcing slots 225 in the above-described configuration are beneficial for maximizing the overall structural strength of each spoke 22.

Note that, in the present application, the ratio of the length of the second ends of the spokes 22 in the circumferential direction of the rim 10 to the circumferential length of the rim 10 is equal to or greater than 1/48 and equal to or less than 1/12. Like this, through optimizing the ratio of the length of the second end of spoke 22 in the circumferential direction of rim 10 to the circumferential length of rim 10, avoid leading to spoke 22 along the length of rim 10 in the circumferential direction undersize because of the ratio undersize between the two, ensure that the welding bead structure between spoke 20 and rim 10 is long enough in the circumferential direction of rim 10, thereby guarantee welding stability between the two, can also avoid leading to spoke 22 along the length of rim 10 in the circumferential direction too big because of the ratio between the two, ensure that ventilation hole 23 has enough big overflow area.
