carhubIncluding the hub bolt fixing seat, drain screw blade and rim, the structure point of the hub bolt fixing seat and the wheel rim is provided with drain screw blade, which discharges the air to the outside of the hub, but the drain screw blade can drive the airflow when the wheel rotates, and the airflow forms wind, but the guide helical blades guide the airflow from inside to outside the car.
The inclined air guide surface will generate a certain concentration of air during the rotation of the wheel, and it will converge with the inclined air guide surface in the inclined direction. Since the inclined air guide surface is arc-shaped, the closer the support rib is to the fixed seat, the greater the inclination angle of the inclined air guide surface.
The supporting ribs gradually increase the concentration of the flowing air from the outside of the rim to the inside, thereby introducing the air into the air vent, because the air vent penetrates the rim, it can directly guide the air to the brake and bearing assembly, effectively improving heat dissipation Effect.
The air outlet is located on the side of the inclined air guide surface close to the center of the rim. The number of support ribs is an even number. The two support ribs form a triangular structure with the rim. The triangular stable structure makes the support ribs support the rim more stable, thereby ensuring the safety of the wheel hub.
