【Abstract】 The road wheel is an important load-bearing part of the tracked vehicle. The application of lightweight materials can increase the weight reduction of the road wheel,reduce the unsprung mass of the vehicle,and thus improve the driving performance of the vehicle. The article summarizes the research and application progress of lightweight materials for road wheels at home and abroad in recent years; at the same time,it summarizes the weight-bearing preparation of lightweight materials such as aluminum alloys,magnesium alloys, glass fiber/epoxy resin, and ultra-high molecular weight polyethylene. The technological method of the wheel and its bottleneck problem,and the prospect of the integrated molding process of the road wheel.更多还原
