The outer surface of the hard alloy layer 6 is covered with an anodized film 7. The outer surface of the anodized film 7 is coated with a ceramic coating 8. The wear-resistant component can provide good wear resistance for the rim 1 and the spoke 5, so it is not easy to cause wear after long-term use, thereby avoiding affecting driving safety; the buffer component includes a first buffer chamber 10 close to the rim 1 and a second buffer chamber 11 close to the wheel center disc 2. The inner cavity of the first buffer chamber 10 is away from the second buffer chamber 11. One end is fixedly connected to a buffer support rod 12. The other end of the buffer support rod 12 passes through the first buffer chamber 10 and extends into the second buffer chamber 11. The extended end of the buffer support rod 12 is fixedly connected to a buffer The buffer support plate 13, the outer wall of the buffer support plate 13 is slidably connected to the inner wall of the second buffer chamber 11, the end of the buffer support plate 13 away from the buffer support rod 12 is fixedly connected to the buffer spring 14 and the other end of the buffer spring 14 is fixedly connected to the inner wall of the second buffer chamber 11, the buffer assembly can provide good buffering capacity for the spoke 5; the reinforcement assembly includes a reinforcement support rod 15, both ends of the reinforcement support rod 15 pass through the adjacent side walls of the spoke 5 and extend to the inner cavity of the spoke 5, the front of the spoke 5 is provided with a second mounting bolt 16, the second mounting bolt 16 passes through the front of the spoke 5 and is threadedly connected to the through end of the reinforcement support rod 15, the reinforcement assembly can improve the overall structural strength, so it is not easy to cause deformation in the event of a driving accident, thereby avoiding affecting the safety of people and vehicles.

[0024] Working process: The wear-resistant component can provide good wear resistance for the rim 1 and the spoke 5, so it is not easy to cause wear under long-term use, thus avoiding affecting driving safety. The cemented carbide layer 6 has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C, and still have high hardness at 1000°C. The anodized film 7 can improve the surface hardness and wear resistance of the rim 1 and the spoke 5, expand the scope of application, and extend its service life. The ceramic coating 8 has the advantages of wear resistance, corrosion resistance, anti-sticking, high hardness, and high temperature resistance. The buffer component can provide good buffering capacity for the spoke 5. When the rim 1 is deformed, external force will act on the rim 1 and squeeze the spoke 5, so that the buffer support rod 12 is squeezed inward, and the squeezing of the buffer support rod 12 will squeeze the buffer spring 14 through the buffer support plate 13, and the buffer spring 14 drives the buffer support plate 13 and the buffer support rod 12 to reset through its own resilience, so as to buffer the external force and reduce the deformation degree of the rim 1 and the spoke 5. Therefore, it is not easy to cause deformation when a driving accident occurs, thereby avoiding affecting the safety of people and vehicles. The reinforcement support rod 15 can provide additional support for each spoke 5, so as to enhance the overall structural stability, and the reinforcement support rod 15 is installed by the second mounting bolt 16, so when a certain reinforcement support rod 15 is broken or deformed, it can be replaced separately without replacing the entire rim 1, so that the maintenance cost can be saved.
