ABSTRACT
This thesis is to combine current situation of the development of automobile industry of miniature electric cars, car wheel edges reducer design, design a kind of mini-bev wheel edge speed reducer, miniature electric cars for driving wheel edges system USES, work torque smaller, but because there is no main reducer and need more than the slowdown. The wheel edges with large vehicles for the structural type gear reducer electric car wheel edges provide reference, narrow gear reducer while increasing structure size than, satisfy wheel edges slowing the use requirement driving system. In recent years, with the rapid development of auto industry, global car total quantities increases unceasingly, car brings the environment pollution, energy shortage, resource exhaustion issues such as more and more outstanding. The increasingly serious oil crisis and the people environmental protection consciousness, the strengthening of the development of automobile industry forward very serious challenges. Using electricity for driving equipment electric car true "is a result of zero emission and become the focus of the world automobile research. In order to protect the human living environment and safeguard energy supply, governments invest a lot of manpower and material resources at the way to seek solutions to these problems. But electric cars (including pure electric cars, hybrid electric cars and fuel cell cars), namely all or part of the electricity can drive motor cars, as power system with high efficiency, energy saving, low noise, zero emissions and other significant advantages in environmental protection and energy saving, has incomparable advantage, therefore it solve the above problem is the most effective way. This thesis miniature electric vehicle designed by the wheel edges with the electric car on the speed reducer can be used provided a reference of the deceleration device form, help electric vehicle design aБайду номын сангаасd development.

要
本论文是结合当今汽车行业发展的形势，对微型电动汽车的车用轮边减速器进行 设计， 设计一种微型电动车用的轮边减速器， 是为微型电动汽车的轮边驱动系统使用， 工作力矩较小，但因没有主减速器而需要更大的减速比。以大型车辆的轮边减速器的 结构型式可以为电动汽车的轮边减速器提供参考，缩小结构尺寸，而增大减速比，满 足轮边驱动系统的使用要求。 近年来随着汽车工业的高速发展，全球汽车总保有量不断增加，汽车所带来的环 境污染、能源短缺，资源枯竭等方面的问题越来越突出。日益严重的石油危机与人们 环保意识的加强，对汽车工业的发展提出了极为严峻的挑战。采用电能为驱动设备的 电动汽车由于能真正实现“零排放”，而成为各国汽车研发的焦点。为了保护人类的 居住环境和保障能源供给，各国政府不惜投入大量人力、物力寻求解决这些问题的途 径。而电动汽车(包括纯电动汽车、混合动力电动汽车以及燃料电池汽车)，即全部或 部分用电能驱动电动机作为动力系统的汽车，具有高效、节能、低噪声、零排放等显 著优点，在环保和节能方面具有不可比拟的优势，因此它是解决上述问题的最有效途 径。 本论文所设计的微型电动汽车用的轮边减速器在电动汽车上的应用提供了一种可 以借鉴的减速装置形式，有助于电动汽车的设计和研发。
