Automobile wheels include hub bolt holders, drainage spiral blades and rims. The structural points of the hub bolt holders and rims are provided with drainage spiral blades to drain air to the outside of the hub, but the drainage spiral blades can drive the air flow when the wheel rotates, and the air flow forms wind, but the guide spiral blades guide the air flow from the inside of the car to the outside of the car.

The inclined wind guide surface will produce a certain concentration of air during the rotation of the wheel, and will converge with the inclined direction of the inclined wind guide surface. Since the inclined wind guide surface is curved, the support ribs are closer to the fixed seat, and the inclined the wind guide surface. The greater the inclination angle.

The support ribs gradually increase the concentration of flowing air from the outside of the rim to the inside, thereby introducing air into the vent, because the vent penetrates the rim, the air can be directly directed to the brake and bearing assembly, effectively improving the heat dissipation effect.

The air outlet is located on the side of the inclined wind guide surface close to the center of the rim. The number of support ribs is even. The two support ribs form a triangular structure with the rim. The triangular stable structure is adopted to make the support ribs support the rim more stable, thereby ensuring the safety of the hub.
