摘要
本文写的是一辆六座电动观光汽车的总体设计。首先是对大量电动汽车资料的查阅,然后从电机的选择,电池的选择着手,根据题目的要求,进行一系列的计算最后得出满足行驶要求的电机和电池。在选好电机和电池后,和设计燃油汽车的底盘一样,并同时综合电动汽车的结构特点,对汽车的传动系统,行驶系统,转向系统,制动系统进行一一分析和设计。在这为电动汽车设计底盘的过程中,要特别注意电动汽车与燃油汽车不同的地方。在我所设计的这辆低速的观光电动车上,它的传动系很简单,没有传统的离合器和变速器,也没有万向传动系统,是电机直接和主减速器用齿轮啮合直接连接,这样使得整个底盘的空间大大增加,整个底盘的布置也可以变的更加自由了。最后在这些的基础上,利用计算所得数据,对汽车进行总布置设计。

Abstract
This article writes an eight tourism electric automobile design. First is to the massive electric automobile material consult, then from the electrical machinery choice, the battery choice begins, according to the topic request, carries on a series putations finally to obtain satisfies the travel request the electrical machinery and the battery. After chooses the electrical machinery and the battery, is same with the design fuel oil automobile chassis, and simultaneously synthesizes the electric automobile the unique feature, to the automobile transmission system, the travel system, the steering system, the braking system carries on 11 analyses and the design. Designs the chassis in this for the electric automobile in the process, must pay attention to the electric automobile and the fuel oil automobile different place specially. Designs in me on this low speed tourism electric automobile, its power transmission is very simple, does not have the traditional coupling and the transmission gearbox, also does not have the rotary transmission system, is the electrical machinery direct and the main gear box with the gear meshing direct connection, like this causes the entire chassis the spatia
