[0002] With the development of commercial vehicles, disc wheel assemblies are widely used. However, they are currently experiencing problems such as oil leakage from wheel hub oil seals, damage to wheel hub bearings, cracking of brake discs, and abnormal ABS signals. The main reason for this is that the high heat generated during braking cannot be dissipated in time, which leads to the transfer of heat to the wheel rim structure, causing cracks or even failure of components such as brake discs.

[0013] The brake disc heat dissipation structure and the wheel-side heat dissipation structure including it provided by this utility model have at least one of the following technical effects: the brake disc heat dissipation structure is designed as a unique heat dissipation circulation channel, which is lighter and has the advantages of better heat dissipation and crack resistance compared with conventional "L" type brake discs. Moreover, the brake disc is heated more evenly, eliminating umbrella-shaped deformation and hot spots; the wheel hub heat dissipation structure is designed as a double-layer shell hollow structure and heat dissipation holes, which can quickly dissipate the heat of the wheel-side bearing and reduce bearing burning failure; the wheel-side heat dissipation structure is designed as a brake disc heat dissipation structure and a wheel hub heat dissipation structure, as well as a heat dissipation channel and ventilation holes connecting the brake disc heat dissipation structure and the wheel hub heat dissipation structure, which has the advantage of fast heat dissipation, greatly reducing the failure problem of the wheel-side structure due to high temperature overheating and improving the service life of components.
