The structure of the automobile rim is simple and can be divided into two parts: 1.Spokes 2.rims.To be precise, the spokes of almost all automobile wheels are currently hollow. The main reasons why they are all hollow designs are： 1.Heat dissipation requirements: If the car is driving for a long time, it will make the wheels of the car very hot; in addition, the braking system will generate a lot of heat.If these heat cannot be released in time, it will cause a big problem for the driving safety of the car and may cause the tires to burst.The hollow design increases the contact area between the spokes of the rim and the air, which is conducive to heat dissipation. 2.Reduce the weight of automobile wheels: As we all know, the lighter the mass under the spring, the better the performance of the automobile, the higher the acceleration and braking, and the higher the fuel efficiency.The hollow design greatly reduces the weight of the wheel rim, and the aluminum alloy also provides sufficient strength for the spokes to support the rim. 3.Material savings: Of course, the hollow design saves the aluminum alloy materials used in wheel rim manufacturing, reduces the production cost of automobile wheel manufacturers, naturally reduces the cost of host manufacturers, and consumers also enjoy the benefits.Below is a pile of aluminum rods.It's all money. 4.More beautiful: Now that Internet celebrities have seen the level of appearance, the wheels are the same.At present, automobile manufacturers are also paying more and more attention to the axle shape design of the wheel rim. Good automobile wheel design can improve the integrity of the automobile shape design and play the role of finishing touch.Hollow spokes can be made in various shapes to meet the needs of different consumers.
