Why are car wheels hollow? Why haven't you seen a fully enclosed one?

(1) heat dissipation requirements: the wheel hub will become very hot when the car runs for a long time; In addition, the braking system will also generate a lot of heat. If this heat cannot be dissipated in time, it will cause great problems to the driving safety of the car and may cause a flat tire. Hollow design increases the contact area between hub spokes and air, which is beneficial to heat dissipation. Give everyone a feeling of overheating and puncture, thrilling!

(2) Reduce the weight of the wheel hub: As we all know, the lighter the unsprung weight, the better the performance of the car, the enhanced acceleration and braking performance, and more fuel-efficient. The hollow design greatly reduces the weight of the wheel hub, and the aluminum alloy also provides enough strength for the spokes to support the wheel rim.

(3) Material saving: Of course, the hollowed-out design saves aluminum alloy materials used in wheel hub manufacturing, reduces the production cost of wheel hub manufacturers, naturally reduces the cost of the main engine factory, and consumers also enjoy benefits. The picture below shows piles of aluminum bars, all of which are money.

(4) More beautiful: Nowadays, online celebrities pay attention to face value, and so do the wheels. At present, automobile manufacturers pay more and more attention to the spoke design of wheel hub. Good wheel hub design can enhance the integrity of the whole vehicle design and play the role of finishing touch. Hollow spokes can be made into various shapes to meet the needs of different consumers.

(5) In addition, totally enclosed wheels are not completely absent in the market at present. FORGIATO, the top luxury wheel hub brand from the United States, has brought us fully enclosed wheels with great personality. The transparent wheel hub of Forgiato-Radurra is a fully enclosed design wheel hub, and its spokes are made of high compression reinforced synthetic glass fiber reinforced plastic used for making space shuttle windows, which has the characteristics of high strength, good toughness, good heat resistance and heat dissipation, so this kind of wheel rim has the impact resistance of the wheel rim and will not cause trouble to the heat dissipation of the brake system.
