Why are the car hubs hollowed out?

The car hub has a simple structure and can be divided into two parts: 1. spoke 2. rims.

To be exact, the spokes of almost all automobile wheels are hollow in design at present. I think the main reasons are as follows: 1. Heat dissipation requirements: If the car is driven for a long time, the hub of the car will be very hot; in addition, the braking system will also generate a lot of heat.

If these heats cannot be 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 spokes of the hub and the air, which is good for heat dissipation. Let us feel the feeling of overheating and blowing out tires.

So exciting! 2. Reduce the weight of the car hub: As we all know, the lighter the mass under the spring, the better the performance of the car, the higher the acceleration and braking performance, and the higher the fuel efficiency. The hollow design greatly reduces the weight of the hub, and the aluminum alloy also provides sufficient strength for the spokes to support the rim.

3. Saving materials: 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 hub manufacturer, 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. More beautiful: Now the Internet celebrities see the level of appearance, and the wheels are the same.

At present, automobile manufacturers are paying more and more attention to the wheel axle shape design of the wheel hub. A good car wheel hub design can improve the integrity of the car shape design and play a finishing touch. Hollow spokes can be made in various shapes to meet the needs of different consumers.
