4T三轴式五档机械滑移齿轮式汽车变速器设计-变速箱
摘要
汽车的行驶状况很复杂，汽车的载货量,道路坡度，路面状况以及交通状况等都要求汽车的牵引力和车速具有较大的变化范围。这就是为什么汽车需要一套可以改变速度的变速系统的原因了。汽车变速器就是协调发动机的转速和车轮的实际行驶速度，用来适应汽车各种运行状况的装置。汽车变速器主要分为机械手动变速器和自动变速器两大类。传统的变速器以手动式为主，价格低廉，至今仍有广泛应用。自动变速器操控性和安全性能比较好，是汽车变速器的发展主流。传统变速器设计周期较长，所以更新速度不是很快。不少公司都没有设立独立的变速器研发机构和生产机构。而是委托专门的变速器生产商生产，甚至直接购买通用的变速器产品。近几年来，计算机技术的飞速发展带动了传统工业的蓬勃发展。在汽车行业，很多大型的计算机辅助软件，大大减少了产品的研发周期，降低了开发难度。

ABSTRACT
Design summary of condition of vehicle auto transmission is complex, tabulation of cars, road slopes, road conditions and traffic conditions, and so requires traction and speed has a large range of cars. That is why the car needs a can change the speed of the speed-change system of reason. Auto transmission is to coordinate the engine speed and the actual speed of the wheels, to adapt to the working condition of vehicle unit. Automobile transmissions are divided into transmission and automatic transmission two kinds of Manipulator. Traditional transmission-manual-dominated, low price, still widely used. Automatic transmission operation and better safety, is the development of automotive transmission. Traditional transmission cycle is longer, so update speed is not very fast. Many companies does not establish independent of transmission research and development institutions and agencies. It commissioned a specialized manufacturer of transmissions, or even general transmission products for direct purchase. In recent years, the rapid development of computer technology has led the traditional industry to flourish. In the automotive industry, many large computer aided software significantly reduces product development cycles and reduce development difficulties.
