In this process, the design and manufacturing level of automobile parts are also constantly improving to meet the increasingly stringent market demand. Wheels are a key component of automobile driving, and their performance and quality have a vital impact on the performance of the entire vehicle. It can be said that high-quality wheels are the basis for ensuring safe, comfortable and efficient driving of automobiles. The performance of wheels directly affects the driving stability of the car. The quality of wheels has an important impact on the comfort of the car. The performance and quality of wheels are also related to the safety of the car. Therefore, it is necessary to continuously improve the design and manufacturing level of wheels to meet the needs of the market and consumers.

[0003] The shortcomings of the existing technology: the traditional wheel manufacturing process often has problems such as heavy weight, low strength, and poor wear resistance. The heavy wheels will not only affect the acceleration performance and fuel efficiency of the car, but also increase the burden on the braking system, thereby affecting the safety performance of the whole vehicle. In addition, due to the insufficient strength of the wheels, fatigue cracks and even breakage are prone to occur, which will pose a great threat to driving safety. Due to poor wear resistance, the wheels are prone to wear, affecting their service life, which means higher maintenance costs for car owners and more waste for the environment. It cannot meet the lightweight and high-performance requirements of modern cars. Therefore, it is necessary to design a lightweight forged aluminum alloy wheel. Utility Model Content
