目录 2 基于 Pro/E 的小型电动车轮边驱动系统设计与运动仿真 摘要： 电动汽车一般使用可再生能源，其能源多元化与高效化，在城 市交通中，可以实现极低排放，甚至零排放。目前 电动车能源主要来自 电 力，在众多的驱动系统形式中，采用轮边减速驱动系统结构形式是目前的 主要发展方向。目前轮边驱动系统主要采用的是轮毂电机，这种 电机成本 较高，制造过程复杂，并且主要应用于大型 电动轿车上，在小型 电动车上 采用结构简单的轮边驱动系统还较少，本文提出了由一级2K-H (NGW)型 行星传动组成的小型 电动汽车用轮边驱动系统，并按照齿根弯曲强度和 3 齿面接触强度计算公式对各级齿轮 行了设计；对各级齿轮、轴、轴承等 行了强度和寿命校核；对行星架的结构、齿轮箱的结构 行设计，并根据 设计结果画出小型电动汽车轮边驱动系统零件图和总装图。 关键词 ：行星齿轮减速器；轮边驱动系统；轮边减速器；NGW ；轮毂 电机； Based on the Pro/E small electric wheel driving system design and simulation Abstract ：Electric vehicles generally use of renewable energy,In the urban transport,the energy diversification and efficiency can achieve very low 4 emissions, or even zero emission.Now EV energy mainly from electricity.In the form of different drive systems,The Reducer Beside the Wheels is the main development direction.In-wheel motor is mainly used in Direct Wheel Drives System.Because the high cost of this motor, difficult to manufacture and mainly used in large-scale electric car,The simple structure side-wheel drive system is less in the small electric car.This paper presents a Small electric vehicle using the side-wheel drive system that consisting of Principle of 2K-V Type Planetary Transmission.and design all the gears according to formulas of bending fatigue strength of the tooth root and the surface contact fatigue strength of the gears; And checking the life and strength of all the gears, shafts, bearings and so on; And design the structure of planet shelf, gears box and sh
