文档介绍：两轴式四档手动变速器设计
摘要
轿车作为一种最常用汽车,已在现代的社会中占有举足轻重的地位。而变速器是汽车传动系统结构中最重要的部分之一,汽车的前进、后退,增速、减速都要靠变速器传动来实现。而且变速器在汽车的动力性和燃油经济性上也有很重要的影响。
本次设计的汽车变速箱主要是从强度方面来对齿轮的尺寸计算及校核,轴的尺寸计算和位置的确定,选择设计满足其承载能力的同步器。另外,针对齿轮作用力的不同,在不同的轴上选择合适的轴承。利用软件AUTCAD完成变速器总成图、第一轴、第二轴、中间轴、各个挡齿轮及同步器的设计。
随着我国汽车行业的迅猛发展,人们对汽车的需求也越来越高。通过对轿车车变速器的设计,我了解到变速器在汽车结构中具有着重要的作用,因此变速器结构的改进对汽车行业的发展与进步具有着深远的意义。

As a monly used mercial vehicles,in modern society occupies a pivo- tal the transmission gearbox is one of most important parts in the automobile transmission system structure,automobile's advance,the backlash,the growth rate,the deceleration must depend on the transmission gearbox transmission to the transmission gearbox also has the very important influence in automobiles power and the fuel oil efficiency.
This design is mainly gear's putation and the examination,the axis size's calcul-ation and the position's determination,the choice design satisfies its bearing capacity the syn- chromesh. Moreover,in view of the gear action's difference, chooses the appropriate bearing on the different pletes the transmission gearbox unit chart,the first axis,the second axis, the intermediate shaft using software AUTCAD, to keep off the gear and the synchromesh design one by one.
Along with our country automobile profession rapid development,the people are also g- etting higher and higher to automobile's demand,Through to the truck transmission gearbox's design,I understood the transmission gearbox is having the vital role in the automobile struct- ure,so the transmission gearbox structure improvement is having the profound significance to the automobile profession development and the progress.
