Why are car hubs hollowed out?

carhubThe structure is simple and can be divided into two parts: 1. Spoke 2. rims.

To be precise, almost allCar wheelsThe spokes are hollow. I think the main reasons are as follows:

1. Heat dissipation requirements: If the car is driven for a long time, the wheel hub of the car will be very hot; in addition, the braking system will also generate a lot of heat. If this heat is not released in time, it will bring a big problem to the driving safety of the car and may cause the tire to burst.

The hollow design increases the contact area between the hub spokes and the air, which is conducive to heat dissipation. Let us feel the sensation of an overheated puncture. So exciting!

2. Reduce the weight of the car hub: As we all know, the lighter the mass under the spring, the better the car performance, the higher the acceleration and braking, and the higher the fuel efficiency.

The hollow design greatly reduces the weight of the hub, and the aluminum alloy also provides enough strength for the spokes to support the rim.

3. Material saving: Of course, the hollow design saves the aluminum alloy material used in the manufacture of the wheel hub, reduces the production cost of the automobile wheel manufacturer, and naturally reduces the cost of the main engine manufacturer, and consumers also enjoy the benefits. Below is a stack of aluminum rods.

It's all money.

4. Prettier: Now that internet celebrities see the look level, the wheels are the same. At present, car manufacturers are also paying more and more attention to the design of the hub's axle shape. A good car wheel design can improve the integrity of the car's design and play a finishing touch.

The hollow spokes can be made in various shapes to meet the needs of different consumers.
