车用双轴输出式电动机设计与仿真

摘  要

 电动汽车是指以车载电源为动力，用电机驱动车轮行驶，符合道路交通、安全法规各项要求的车辆。由于对环境影响相对传统汽车较小，其前景被广泛看好，但当前技术尚不成熟。
 电动汽车的动力核心即是电动机。电动机是一种实现机、电能量转换的电磁装置。电动机的功能是将电能转换成机械能，它可以作为拖动各种生产机械的动力，是国民经济各部门应用最多的动力机械。电动机技术是一项相当完善的技术。本文从与以往不同的研究方向，结合电动机的工作特点，实现在有限能源条件下，满足电动汽车需要的目的。
 本文概述了电动汽车的发展历史、分类、特点、发展趋势以及车用双轴输出式电动机的基本结构、传动简图、工作原理以及优缺点。对车用双轴输出式电动机进行数学建模，控制系统进行仿真，根据设计要求，进行了传动方案的设计、传动比设计,设计了传动机构中的行星齿轮换向机构，差速机构。

Double Output shaft Motor Design for Vehicles

ABSTRACT

   The electric vehicle was a kind of machine which was powered with power supply on board of vehicle, driven with motor, was up to the standard of traffic and rule of law. Because the environmental impact was less than traditional automobile, its prospects were widely valued, but the current technology was not mature. The dynamic core of electric vehicle technology was motor.
 Motor was a electromagnetic device that achieved electric energy transformed to mechanical energy. Motor’s function was transforming electric energy into mechanical energy, it could be used as a kind of power which was dragging various production in sectors of the national economy, was the most widely dynamic mechanical application. Motor technology was a quite perfect technology. This article was from different from direction of previous research, and combining the characteristics of the electric motor，under the condition of limited energy，realized the purpose which met the demand of electric vehicle.
 This paper summarized the history and development of electric vehicle, classification and characteristics, developing tendency，and basic structure, transmission diagram, working principle and advantages and disadvantages of double Output shaft motor. It made the mathematical modeling, control system, and simulation of double Output shaft motor, according to the design’s requirements, designed the transmission scheme, transmission, the transmission mechanism of Planetary tumbler and differential mechanism.
 
 Key words: electric vehicle double Output shaft motor design developing tendency
