摘 要
隨著汽車工業(yè)的迅猛發(fā)展，車型的多樣化、個(gè)性化已經(jīng)成為汽車發(fā)展的趨勢(shì)。而變速器設(shè)計(jì)是汽車設(shè)計(jì)中重要的環(huán)節(jié)之一。它是用來(lái)改變發(fā)動(dòng)機(jī)傳到驅(qū)動(dòng)輪上的轉(zhuǎn)矩和轉(zhuǎn)速，因此它的性能影響到汽車的動(dòng)力性和經(jīng)濟(jì)性指標(biāo)，對(duì)轎車而言，其設(shè)計(jì)意義更為明顯。在對(duì)汽車性能要求越來(lái)越高的今天，車輛的舒適性也是評(píng)價(jià)汽車的一個(gè)重要指標(biāo)，而變速器的設(shè)計(jì)如果不合理，將會(huì)使汽車的舒適性下降，使汽車的運(yùn)行噪聲增大。本設(shè)計(jì)針對(duì)乘用車變速器進(jìn)行系統(tǒng)深入的研究.
本設(shè)計(jì)基于捷達(dá)變速器，結(jié)合機(jī)械變速器的設(shè)計(jì)方法，深入研究了變速器傳動(dòng)比的計(jì)算，擋數(shù)的分配，齒輪參數(shù)的計(jì)算，軸及軸承的選擇等，從而使乘用車的舒適性和動(dòng)力性有很大的提高。

ABSTRACT
With the rapid development of automobile industry, the diversity of models, individual has become 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 vehicles comfort is an important index for evaluation of car, and transmission design, if unreasonable, will decrease the comfort 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 design is based on Jetta transmission, combined 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 passenger comfort and dynamic have greatly improved.
Keywords: transmission ratio; Keeps off the number; gear parameters; axis; bearings
