摘  要
随着全球气候变化，石油资源的不断减少，各国对环境和能源问题越来越关注，在汽车行业推出的各项新能源汽车补贴也推动了全球汽车工业结构升级，动力系统电动化转型。电动汽车不仅满足了人们的日常代步需求，还有零排放污染，经济型，稳定性较高等优点，无疑是未来几十年内汽车行业的发展重点。
在目前电动汽车的研究中，续航里程成为了主要发展问题。在有限的能源储
  备且不影响动力性的前提下提升续航里程，优化电动汽车各零部件设计成为了许多厂家的研究目标。本文以某一厂家电动车基本模型和动力性需求为基本参数，首先选择了电机和驱动桥的总布置形式，再根据基本参数选择了合适电机，计算传动比。对驱动桥的一系列零部件进行了设计计算。在保证强度的前提下尽可能减少质量，优化设计。在设计计算后通过CATIA建模和CAD绘图完成了一套完整的电动车驱动桥图纸。

Abstract
With global climate change and the continuous reduction of oil resources, countries are paying more and more attention to environmental and energy issues. Various new energy vehicle subsidies launched in the automobile industry also promote the upgrading of global automobile industry structure and the transformation of electric power system. Electric cars not only meet People's Daily transportation needs, but also have the advantages of zero emission pollution, economic type and high stability, which will undoubtedly be the focus of the development of the automobile industry in the coming decades.In current research on electric vehicles, range has become a major development issue. In limited energy storage.It has become the research goal of many manufacturers to improve the range and optimize the design of various parts of electric vehicles without affecting the power performance.
In this paper, the basic model of an electric vehicle manufacturer and the demand for power performance are taken as the basic parameters. Firstly, the general layout of the motor and drive axle is selected, and then the appropriate motor is selected according to the basic parameters to calculate the transmission ratio. A series of parts of the drive axle are designed and calculated. Minimize quality and optimize design while maintaining strength. After the design calculation, a complete set of electric vehicle drive axle drawings were completed through CATIA modeling and CAD drawing.
Key Words：Electric cars; Drive axle; reducer
