Abstract: Hub drive is a new driving type of electric vehicle, which integrates the power, transmission and braking of vehicle into the hub to form an integrated "electric driving wheel". The hub of traditional car can't meet this integration, so a new design of hub is needed. According to the service conditions of electric driving wheel, an electric driving wheel-hub is designed to meet the requirements of electric vehicle. The simulation results show that the bearing capacity, stiffness and strength of the wheel-hub can meet the requirements of vehicle driving conditions. The research results have a certain reference value for the development and promotion of hub motor-driven electric vehicles.

摘要： 轮毂驱动是电动汽车的一种新的驱动形式，它将汽车的动力、传动和制动三者集成在 轮毂内，形成一体化“电驱动轮”。传统汽车的轮毂无法满足这种集成，因此需要进行轮毂的 全新设计。针对电驱动轮使用条件，设计了一种满足电动汽车专用的电驱动轮毂。仿真结果 表明，轮毂的承载能力、刚度、强度都能满足汽车行驶工况要求。研究成果对轮毂电机驱动 电动汽车的研发、应用具有一定的参考价值。
