摘　　要：针对车辆所需传动比较大时传统行星齿轮轮毂减速器存在零部件多、轴向尺寸大及轮系周边安装复杂的问题,以电动轿车为研究对象,提出了一种基于单级章动传动的新型轮毂驱动减速器。阐述了其工作原理和传动过程,完成了结构设计和传动效率计算,建立了虚拟样机模型,并开展了有限元分析仿真,探讨了减速器在静载荷下最大接触应力的产生部位与产生原因,验证了结构的可靠性与合理性。To solve the problems that the conventional planetary gear wheel hub reducer has many parts,large axial dimensions and complicated installation around the wheel system when the vehicle requires a relatively large transmission,and taking the electric car as the research object,this study proposes a new type of wheel hub drive reducers based on single-stage nutating transmission,describes the working principle and transmission process,completes the structural design and transmission efficiency calculation,and establishes the virtual prototype model.The finite element analysis is carried out to discuss the location and cause of the maximum contact stress of the mechanism under a static load.The reliability and rationality of the structure are verified.
