摘要
 本文简要介绍了电动三轮车的分类、用途以及各个类型的电动三轮车的优缺点。并根据我对电动三轮车的市场调查的情况进行分析研究，并对电动三轮车的某些结构做了简要的介绍、改进和整合。
首先，就电动车的发展过程发展前景以及电动车在发展过程中存在的问题做了简要的介绍和分析，并对世界上其它国家电动车的发展状况做了简要的叙述。
其次，本文对目前市场上的所具有的电动三轮车的类型做了一个详细的介绍，并对各个类型的电动三轮车的配置、用途、适用人群、优缺点做了简要的介绍。
最后，经过认真总结和对市场的分析并利用四年来所学的知识，在指导老师和任课老师的指导和其他同学的帮助下，对电动三轮车的整车参数、外形尺寸、前叉结构、驱动系统和制动系统做了简单的设计和改进。

关键词： 电动三轮车，前叉结构，驱动系统，制动系统   

Abstract
This paper introduces the classification of electric tricycle, uses various types of electrical as well as the advantages and disadvantages of tricycles. And according to my electric tricycle for market research analysis of the situation, and some of the structure of electric tricycle a brief introduction, improvement and integration.
First of all, on the development of electric vehicles and electric vehicle development prospects in the development of problems in the course of a brief description and analysis, and other countries in the world, the development of electric cars a brief description.
    Secondly, this article on the current market has the type of electric tricycle has made a detailed introduction to the various types of electric tricycle configuration, usage, the application of people, the advantages and disadvantages of doing a brief introduction.
    Finally, after a careful summary and analysis of the market and take advantage of four years of knowledge, in the guidance of teachers and classroom teachers and other students with the help of the whole of the electric tricycle parameters, dimensions, front fork structure, drive system and the braking system to do a simple design and improvement.

Keywords: electric tricycle, fork, drive system, brake system
