摘要
汽车已成为当今人类社会不可缺少的工具,是城市居民日常生活的一部分,%左右的社会总劳动力的就业之一。汽车与人民的紧密度越来越紧,他对人类社会进步产生着巨大的推动作用,世界上汽车保有量也与日俱增。但是汽车的飞速发展和数量的日益增多给人类带来了麻烦,尤其是影响人类可持续发展的环境污染的问题和出现能源短缺问题。人们开始关注电动汽车,电动汽车可以实现零排放,无污染,无噪声。所以研究电动汽车势在必行。
本次设计主要研究电动汽车的部分内容,包括电动机的选择,减速器差速器的设计,制动系统的设计四部分内容。总的思路是通过使用变频调速电动机调节车轮转速,减速器起减速增扭的作用,差速器实现同一轴上的两轮在转弯时以不同的速度行驶。制动系统是电动汽车不可缺少的一部分,特别是旅游观光车需要频繁的启停,制动系统必须稳定且刹车稳定。

TWELVE SIGHTSING ELECTRIC CAR
ABSTRACT
Cars have e such an indispensable tool of human society, is the city residents part of daily life, he can pull times the related industrial and solve 10% of the total social Labour of one of employment. Cars and people's close degree more and more tight, he human society advances to such a vast role, auto possession in the world was growing. But the bus rapid development and increasing the number of brought trouble, especially the impact of human sustainable development of environmental pollution problems and appear energy shortage. People begin to pay close attention to electric cars, electric cars can realize zero emissions, no pollution, no noise. So the electric car is imperative.
The main research electric car design part of the content, including the choice of motor, gear reducer of differential design, braking system design four sections. The idea is through the use of variable frequency speed regulation wheel speed motor, gear reducer increasing the role of the slow twist, differential realize the same shaft two rounds in turning to the different speed. Braking system is an indispensable part of the electric car, especially tourism car need frequent rev. Stop, braking system must be stable and braking stability.
