文档介绍：摘要
随着汽车工业的迅猛发展,车型的多样化、个性化已经成为汽车发展的趋势。而
变速器设计是汽车设计中重要的环节之一。它是用来改变发动机传到驱动轮上的转矩
和转速,因此它的性能影响到汽车的动力性和经济性指标,对轿车而言,其设计意义
更为明显。在对汽车性能要求越来越高的今天,车辆的舒适性也是评价汽车的一个重
要指标,而变速器的设计如果不合理,将会使汽车的舒适性下降,使汽车的运行噪声
增大。本设计针对乘用车变速器进行系统深入的研究.
本设计结合机械变速器的设计方法,深入研究了变速器传动比的计算,挡数的分
配,齿轮参数的计算,轴及轴承的选择等,从而使乘用车的舒适性和动力性有很大的
提高。

ABSTRACT
With the rapid development of automobile industry, the diversity of models, individual
has e a developing trend. The transmission design is an important part of automotive
design one. It is used to change the engines torque and reached the driving wheel speed, so
its impact on vehicle dynamic performance and economy indicators, on cars, its more
obvious sense of design. Performance in increasingly high demand on the car today, the
fort is an important index for evaluation of car, and transmission design, if
unreasonable, will decrease fort of the automobile, so that the car is running the
noise increases. The design for the passenger car transmission system in-depth study carried
out
The bined with mechanical transmission design, in-depth study of the
transmission gear ratio calculation, the distribution of the number block, the calculation of
gear parameters, choice of shaft and bearing, so fort and dynamic have
greatly improved.
Key words: Transmission Ratio; Keeps Off The Number; Axis; Bearings
