Description

Technical Field

[0001] The utility model relates to the technical field of the connection between a spoke - less rim and a driving wheel end in a vehicle, and particularly relates to a wheel connection structure. Background Technique

[0002] Rims are structurally divided into ordinary rims with spokes and spoke - less rims. Among them,

[0003] The ordinary rim with spokes relies on the spoke plate to fit with the brake drum or the hub flange surface, and generates a frictional torque by pressing the two fitting surfaces to achieve power (torque) transmission; the spoke - less rim uses its inner conical surface to fit with the outer conical surface on the brake drum, hub or connecting plate, and generates a frictional torque by pressing the two conical surfaces to achieve power (torque) transmission.

[0004] The ordinary rim with spokes is mostly used on highway vehicles, while the spoke - less rim is mostly applied to mining dump trucks running on unpaved roads.

[0005] Compared with highway vehicles, mining dump trucks have the characteristics of serious overloading and harsh operating conditions. When using ordinary rims with spokes, faults such as spoke plate welding detachment (the weld between the spoke plate and the rim fails) and spoke plate deformation often occur; compared with ordinary rims with spokes, the structure of the spoke - less rim is simpler and more reliable, and there is no risk of spoke plate deformation and detachment.

[0006] However, the existing installation and connection structure of the spoke - less rim has problems of complex structure and inconvenient disassembly and assembly of the rim during vehicle maintenance, such as the structure shown in patent CN209795453U.
