Commercial vehicle wheel heat dissipation device and wheel

The invention relates to a commercial vehicle wheel heat dissipation device and a wheel, the heat dissipation device comprises a fan blade assembly, the fan blade assembly is fixedly installed in an offset space of a rim through an installation base, and an axle half shaft rotates to drive the fan blade assembly to rotate synchronously. A fan blade assembly is arranged in a wheel offset space, when a vehicle runs, an axle half shaft rotates to drive the fan blade assembly to rotate synchronously, after high-temperature gas in a braking system enters a wheel cavity from rim heat dissipation holes, the fan blade assembly rotates to drive high-temperature gas flow to circulate, heat is accelerated to be dissipated outwards in the wheel axle direction, and the braking effect is improved. Therefore, the effect of reducing the wheel temperature is achieved. The structure does not need to be independently started manually, does not need to additionally provide driving kinetic energy, and is time-saving and labor-sav
