1.Multi-piece alloy wheels

　　There are two-piece and three-piece alloy wheel hubs.Several parts of the wheel hub are manufactured by forging and spinning,and then connected by titanium bolts.These products are light in quality,high in strength and superior in performance,but they are expensive.Mainly used in various championship racing cars and high-end luxury cars.In all levels of the world's car races,whether it is a car or a motorcycle,no matter under what conditions,it is required that the vehicle can accelerate the speed from zero to 100km/h in just 3s,so the wheels need to be on the track It can withstand the impact of the overloaded state caused by extremely high lateral acceleration,extremely high operating speed and harsh conditions,and the temperature rise caused by the strong wear of the tires.In this environment,the multi-piece aluminum wheel hub It has withstood the test of various hard environments.Although the product quality is light,due to the use of advanced manufacturing technology,the product has high structural strength,and the multi-piece combination shape gives a thick and strong feeling.

　　2.One-piece racing alloy wheels

　　F1 racing requires single-piece wheels.In order to ensure the performance of the wheels and the requirements for vehicle weight reduction,usually forged blanks are used to form the production by the spinning process to ensure the high performance and the lightest of the products.Compared with cast alloy wheels,the mechanical properties are improved by more than 18%,and the quality can be reduced by about 20%.The one-piece alloy wheels specially designed and manufactured for F1 racing cars have withstood the test of various difficult environments.However,passenger car alloy wheels are not as demanding as the performance requirements of racing cars.Integral low-pressure cast alloy wheels are enough to meet their performance requirements,but passenger cars pay more attention to the appearance and aesthetic design of alloy wheels.Affected by motor sports and the requirements of energy saving and aesthetics,automotive alloy wheels are also undergoing changes.More sporty large-diameter,soft-spoke alloy wheel designs and lightweight alloy wheel designs are the main development trends of automotive alloy wheels.The direction to pursue.

　　3.Built-in air alloy wheels

　　In order to minimize the quality of the wheel,a new concept of a new lightweight alloy wheel with an air alloy wheel came into being.The cavity technology is used to further reduce the quality of the wheel.This alloy wheel is divided into one-piece and two-piece combination.The single-piece built-in air alloy hub uses cavity technology to make all the spokes of the hub and the inner and outer shoulders of the rim into cavities,which greatly reduces The quality of the wheel is reduced by 20%compared with the alloy wheel of the same structure,but the performance is greatly improved;the two-piece built-in air alloy wheel is made into a cavity at the inner shoulder of the wheel rim,Greatly reducing the quality of the wheel hub,compared with the same structure alloy wheel hub by 5%,and improve the performance of the product.This type of alloy wheel hub uses cast blanks and uses a spinning process to complete the cavity.
