Abstract: In order to improve the transmission efficiency of the formula student electric China (FSEC) racing car under extreme working conditions such as rapid acceleration and cornering, this article introduces the wheel reducer system and its working principle, specific research and calculation are carried out on various design parameters of the system. The research and design of system components and the process of ANSYS static simulation analysis are briefly described. The research results show that the wheel planetary gear reducer operates stably and reliably, is easy to assemble, has a lighter overall weight compared to other transmission methods, and has a higher transmission efficiency. The system will be installed on the No.10 racing car of Liaoning University of Technology wande electric racing car team to verify its design rationality in practice. The research results can provide reference for the design of wheel planetary systems in subsequent racing car, in order to improve the transmission efficiency of racing car, meet the lightweight requirements of racing car, and improve racing car performance.
