微型可伸缩电动汽车的总体设计 摘要 现如今能源问题随着环境问题的出现越来越受到人们的关注，而电动汽车随着此类问题的出现成为了一种主流发展趋势。电动汽车能够实现零排放，因此大大减少了污染物的排放，改变了当今内燃机车辆对环境的影响对能源的过度需求。另一方面随着现如今城镇化的一步步发展，停车位的解决方法一直是城市规划的重点，而微型可伸缩电动汽车可以很好的解决停车难的问题。它的出现大大减少了车辆占地，为城市其他发展节省出了相当大的空间，有利于城镇的高速发展。 本次设计的微型可伸缩电动汽车可以很好的解决以上问题，满足节能，减少占地空间的要求。这次设计主要涉及小车车身总体布置，参数的选择，驱动形式，制动形式，伸缩机构的设计，悬架机构及参数选择，传动及控制等。 关键词： 微型汽车 可伸缩汽车 电动汽车 可伸缩机构 The tiny scalable overall design of electric vehicles Abstract Energy problem now with the emergence of environment problem more and more get the attention of people, and the electric car with the emergence of these problems has become a mainstream trend.Electric cars can achieve zero emissions, thus greatly reducing the emissions of pollutants, changed the environmental impact of todays internal combustion engine vehicle excess demand for energy. On the other hand, step by step, as now the urbanization development of parking solution has always been the focus of the urban planning, and tiny scalable electric cars can be a very good solution to solve the parking problem. It greatly reduces the vehicle cover, save other urban development out of the considerable space, is conducive to the rapid development of towns. The design of the miniature scalable electric cars can well solve the above problem, satisfy the energy conservation, reduce the space requirements. This is mainly concerned with the general arrangement of the car body design, the choice of parameters, drive form, the form of braking, the design of telescopic mechanism, suspension mechanism and parameter selection, transmission and control, etc. Keywords： Bubble car Scalable car Electromobile Scalable organizations 目录 1 文献综述 6 1.1 课题背景 6 1.2 国内外发展概况 7 1.3 研究意义 10 2．毕业设计（论文）工作过程 11 2.1 工作原理及设计要求 11 2.2形式选择与结构分析 13 3.微型可伸缩电动汽车的总体设计 14 3.1汽车形式的选择 14 3.2汽车主要参数的选择 15 （1）汽车主要尺寸的确定 15 3.3轮胎的选择 16 3.4汽车质量参数的确定 16 3.4.1整车整备质Mo 16 3.4.2汽车的载客量和装载质量 17 3.4.3汽车的总质量Ma 17 3.4.4轴荷分配 17 3.5汽车性能参数的确定 17 3.5.1动力性参数（最高车速、加速时间、上坡能力、比功率、比转矩） 17 3.5.2汽车最小转弯直径Dmi
