Research on Lightweight Wheel Hub Design and Its Improvement on Vehicle Fuel Economy

This article focuses on the manufacturing process of lightweight wheel hubs. The innovation of low-pressure and vacuum technology in precision casting improves the quality of car and racing wheel hubs, saving energy and increasing efficiency; Conventional and isothermal forging with strong forging can meet the demand for strong, tough and lightweight wheels for heavy-duty vehicles and high-performance sedans; Integrated spinning process and weight reduction in one, multi pass spinning helps expand the range of new energy vehicles; Additive manufacturing breaks the shackles of design and materials with 3D printing, creating a Xintiandi for aviation and high-end sports cars. These processes empower wheel hub lightweighting from multiple dimensions, promoting the energy-saving and efficient development of vehicles.
