The hub bolt fixing plate, drain screw blade and flange, and the point of the wheel hub bolt fixing plate and flange structure are equipped with drain screw blades, and the air flows to the side of the hub, but when the screw blade rotates to drain water, it can drive the airflow and form a wind. , but the airflow of the lead screw blades is from the inside to the outside. During the rotation of the wheelset, the inclined air surface will generate a certain concentration of air, which will converge with the inclined direction of the inclined air surface. Since the inclined air surface is curved and the support rib is close to the fixed seat, the inclined air surface has a large inclination. The support ribs gradually increase the air concentration from the outer side of the rim to the inner side of the rim, thereby directing the air through the rim vents to the brake and bearing assembly, effectively increasing heat dissipation.
The outlet is located on the side of the inclined wind deflector, close to the center of the rim. The number of supporting ribs is uniform. The two ribs form a triangular structure with the sides. The triangular stable structure is adopted to make the supporting ribs more stable and ensure the safety of the wheel hub.
