摘 要 变速器用来改变发动机传到驱动轮上的转矩和转速，目的是在原地起步、爬坡、转弯、加速等各种行驶工况下，使汽车获得不同的牵引力和速度，同时使发动机在最有利的工况范围内工作。是汽车总成部件中的重要组成部分，是主要的传动系统。变速器的结构对汽车的动力性、经济性、操纵的可靠性与轻便性、传动的平稳性与效率等都有直接影响。 利用AutoCAD软件绘制装配图和零件图等项内容。关键词：变速器；齿轮；同步器；设计；ABSTRACT Transmission used to change to the drive wheels on the engine torque ancd rotational speed, the purpose is in situ beginning, climbing, turn, accelerate, etc. Various kinds of driving conditions, make cars get different traction and the engine speed, and at the same time at the most favorable conditions range work. Car assembly components is the important constituent, is one of the main transmission system assembly. The transmission of the structure of the power, economy, car reliability and manipulation of portability, transmission and steadiness and efficiency to wait to have direct effect. This design research two axis five block manual gearbox, its purpose is skillfully use and mastering mechanical principle, mechanical design, knowledge, and use AutoCAD AutoCAD software rendering drawings and parts chart and so on several content. The working principle of the transmission of this method and transmission each block and gear shaft to do a detailed design calculation, and the intensity of some standard check, the selection. The transmission scheme design and transmission components of the transmission about the choice of materials. This paper will outline the present situation and developing trend of the transmission is introduced, and the latest development of transmission field situation. The principle of work, explains the of different transmission transmission scheme comparison and selection of rational structure scheme design. Each block of the transmission gear and axis and bearing a detailed design calculation, and the intensity and rigidity check calculation for these components, and choose the appropriate engineering material and heat treatment method. For some standard of the driving scheme selection and transmission of the comparison and sele
