[0002] In many fields such as transportation, construction machinery, and new energy equipment, wheels serve as core load-bearing and transmission components, and their performance directly affects the overall operating efficiency, energy consumption level, and safety of the equipment. As the industry's requirements for energy conservation, emission reduction, and efficient production continue to increase, lightweight wheel design has become one of the core directions of technological research and development. Traditional wheels have a front window design, with brake discs and calipers visible through the window. However, the large amount of material used in the overall structure results in excessive wheel weight, which not only increases the energy consumption of the equipment but also exacerbates the load on the transmission system, reducing the overall operational flexibility. Furthermore, the traditional structure has a complex manufacturing process involving multiple steps and cumbersome assembly, which not only prolongs the production cycle but also increases processing costs and scrap rates, making it difficult to meet the demands of large-scale, high-efficiency production.

[0031] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0032] Please refer to the reference. Figure 1 — Figure 5 This application provides a lightweight wheel 1, including a rim 11, a first spoke 12, and a second spoke 13. The rim 11 has an accommodating cavity 111. The first spoke 12 is connected to the second spoke 13 and is located within the accommodating cavity 111 and connected to the rim 11. The first spoke 12 has a first protrusion 121 and a plurality of first through holes 122, which are arranged around the first protrusion 121 and located on the side of the first protrusion 121. The second spoke 13 has a fixed connection portion 131 and a plurality of second through holes 132, which are arranged around the fixed connection portion 131. The plurality of first through holes 122 and the plurality of second through holes 132 correspond one-to-one and are connected.

[0033] It should be noted that the inner and outer sides of the first protrusion 121 are set as inclined surfaces, and the first through holes 122 are distributed in a direction that is neither horizontal nor vertical on the inclined surfaces. The number of the first through holes 122 and the second through holes 132 is not specifically limited here. In this embodiment, the first through holes 122 and the second through holes 132 are circular holes, but in other embodiments they may be other shapes, which are not limited here. The first through holes 122 and the second through holes 132 are used to dissipate heat generated during braking and other processes. This facilitates the overall processing and assembly of the wheel, reduces the overall weight of the wheel, and improves processing efficiency.

[0034] Specifically, a first protrusion 121 is provided on the first wheel spoke 12, and a plurality of first through holes 122 are arranged around the first protrusion 121; a fixed connection part 131 is provided on the second wheel spoke 13, and a plurality of second through holes 132 are arranged around the fixed connection part 131; the first through holes 122 and the second through holes 132 are connected one-to-one, so that the heat generated by the wheel during braking friction and the heat generated by the tire can be dissipated in time. The multi-hole design can also achieve the effect of weight reduction. The first wheel spoke 12 is fully shielded, completely covering the braking system, which can effectively protect the braking system and prevent mud and sand from splashing or getting dirty during driving.

[0040] It should be noted that the first protrusion 121 and the second protrusion 133 have opposite protrusion directions.

[0041] The rim 11 has a load-bearing body 112, a first side 113, and a second side 114; the first side 113 and the second side 114 are arranged around both sides of the load-bearing body 112 and together form an accommodating cavity 111; the first spoke 12 is connected to the load-bearing body 112, and the second spoke 13 is connected to the load-bearing body 112. It is understood that the accommodating cavity 111 is used to accommodate the first spoke 12 and the second spoke 13.

[0042] It should be noted that the outer ring of the load-bearing body 112 is provided with a first support portion 1121 and a second support portion 1122; one side of the first support portion 1121 is connected to the first side 113, and the other side of the first support portion 1121 away from the first side 113 is connected to the second support portion 1122; one side of the second support portion 1122 is connected to the second side 114, and the other side of the second support portion 1122 away from the second side 114 is connected to the first support portion 1121.
