Through optimizing the welding position of rim 10 and spoke 20, the axial medial surface of the outer periphery department of spoke 20 and the inner wall face that lies in its rim department of transition ring slab 122 of rim 10 are welded, so, after spoke 20 and rim 10 fixed connection, not only ensured the connection steadiness of both, and spoke 20 is located the axial one end of rim 10, ensure that spoke 20 can not occupy too many spaces of the axial inboard of rim 10, thereby reserved sufficient installation space for the brake mechanism of vehicle, ensure that have sufficient heat dissipation space after the brake mechanism is installed, guarantee that the heat that brake mechanism produced in the braking process can in time disperse, avoid accelerating the ageing of tire because of the heat accumulation makes the temperature rise of tire, prolonged the life of tire effectively, avoided serious accident emergence such as tire ignition or tire burst simultaneously, ensure that the vehicle can normally travel, ensure user's life safety.

In the present application, the installation space surrounded by the installation ring plate 11 is used for installing the brake mechanism.

As shown in fig. 1 and 4, the spoke 20 includes a center mounting plate 21 and a plurality of spokes 22, wherein the plurality of spokes 22 are radially spaced around the circumference of the center mounting plate 21, a vent hole 23 is formed between two adjacent spokes 22, and a first end of each spoke 22 is connected with the center mounting plate 21 and a second end of each spoke 22 is welded to the inner wall surface of the rim 10. In this way, the spoke 20 in the structure effectively reduces the processing and manufacturing difficulty of the spoke 20 and improves the economical efficiency 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 dispersed in time, and the phenomenon that the tire fires or bursts due to the fact that the tire is in a high-temperature state for a long time in the running process of the vehicle is avoided.

Optionally, the surface of the transition ring segment 122 facing the spoke 20 is a first curved connecting surface, and a second curved connecting surface that is fittingly attached to the first curved connecting surface is formed on the axially inner side surface of the spoke 22 at a position opposite to the first curved connecting surface. In this way, the spoke 20 is welded with 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 transition ring plate section is increased, and the stability of the welding position between the spoke and the transition ring plate section 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 bends to extend in the axial direction of the rim 10; the spoke 22 comprises a spoke body 221, a first radial plate body 222, a transition plate body 223 and a second radial plate body 224 which are sequentially connected, 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. In this way, the provision of the second ring plate segment 123 acts as an axial stop limit for the spokes 20, ensuring that the spokes 20 are always located at one axial end of the rim 10 after the spokes 20 are mounted to the rim 10; in addition, the second curved connecting surface is formed on the transition plate body 223, so that the second curved connecting surface of the spoke 20 is ensured to be matched with the first curved connecting surface of the rim 10, and the welding stability between the two is ensured.

Alternatively, on the axis of the rim 10, the central mounting plate 21 is located near the center of the axis of the rim 10 with respect to the second ends of the spokes 22, and each spoke body 221 extends in a bent shape to connect the central mounting plate 21 and the first radial plate 222. In this way, the central axis of the spoke 20 coincides with the central axis of the rim 10, and the whole gravity center of the wheel is close to the center of the rim 10, so that the coaxiality and stability of the wheel during rotation are improved, and the whole aesthetic feeling of the wheel is improved.

In the present application, the width of each spoke 22 is gradually reduced in a direction away from the center mounting plate 21 as shown in fig. 1 and 4 in order to ensure that the flow area of the vent holes 23 is sufficiently large, while ensuring that each spoke 22 has sufficient strength. In this way, the overall flow-through area of the vent holes 23 in the circumferential direction of the rim 10 is increased, ensuring that heat generated during braking of the vehicle can be dispersed in time.

Thus, the provision of the first structural reinforcement 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 reinforcement grooves 213 ensures that the center mounting plate 21 has sufficient strength, thereby increasing the overall structural strength of the spokes 20; further, the center through hole 211 is provided for the wheel-axle connection, and the plurality of mounting holes 212 are provided for the fastening mounting of the wheel-axle.

Alternatively, the width of the first structural reinforcement groove 225 gradually decreases in a direction away from the center mount plate 21, and the depth of the first structural reinforcement groove 225 gradually decreases in a direction away from the center mount plate 21. Thus, the first structural reinforcement slots 225 of the above-described construction are advantageous in maximizing the overall structural strength of each spoke 22.

In the present application, the ratio of the length of the second end of the spoke 22 in the circumferential direction of the rim 10 to the circumferential length of the rim 10 is 1/48 or more and 1/12 or less. In this way, by optimizing the ratio of the length of the second end of the spoke 22 in the circumferential direction of the rim 10 to the circumferential length of the rim 10, the length of the spoke 22 in the circumferential direction of the rim 10 due to the excessively small ratio therebetween is prevented from being excessively small, the weld bead structure between the spoke 20 and the rim 10 is ensured to be sufficiently long in the circumferential direction of the rim 10, the welding stability between the spoke 20 and the rim 10 is ensured, and the excessively large length of the spoke 22 in the circumferential direction of the rim 10 due to the excessively large ratio therebetween can be prevented from being ensured, and the vent hole 23 is ensured to have a sufficiently large overflow area.

Preferably, the ratio of the length of the second end of the spoke 22 in the circumferential direction of the rim 10 to the circumferential length of the rim 10 is 1/24.

Optionally, the number of spokes 22 is 3 or more and 12 or less. In this way, the vent holes 23 are ensured to have a sufficiently large flow area while ensuring that the spokes 20 can perform a stable supporting function on the rim 10.
