carhubDrainage spiral blades are set at the points of the bolt fixing plate, drainage spiral blade and wheel rim, hub bolt fixing plate and flange structure, and the air flows to the side of the hub. , but the airflow of the lead screw blades flows from the inside to the outside.
During the rotation of the hub, a certain concentration of air will be generated on the inclined air guiding surface, which will converge with the inclined direction of the inclined air guiding surface. Since the inclined air guiding surface is curved and the supporting rib is close to the fixed seat, the inclination angle of the inclined air guiding surface larger.
The support ribs gradually increase the concentration of air flowing from the outside of the rim to the inside of the rim, thereby drawing air through the vents of the rim and directing the air to the brake and bearing assembly, effectively increasing heat dissipation.
The air outlet is located on the side of the inclined wind deflector near the center of the rim. The number of supporting ribs is even. The two supporting ribs form a triangular structure with the edge. The triangular stable structure is adopted to make the supporting ribs more stable and ensure the safety of the wheel hub.
