摘 要
汽车的诞生，车的发展，在历史的长河中给我们留下了点点滴滴。汽车自上个世纪末诞生以来，已经走过了风风雨雨的一百多年。从卡尔.本茨造出的第一辆三轮汽车以每小时18公里的速度，跑到现在，竟然诞生了从速度为零到加速到100公里/小时只需要三秒钟多一点的超级跑车。这一百年，汽车发展的速度是如此惊人！同时，汽车工业也造就了多位巨人，他们一手创建了通用、福特、丰田、本田这样一些在各国经济中举足轻重的著名公司。这篇资写着许多有趣的故事，在中国已经成为世界五大汽车强国之际，让我们一起来回望汽车的发展历史，体会汽车给我们带来的种种欢乐与梦想……
变速器作为汽车的一个重要组成部分，是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。
变速器有机械式手动变速器和机械式无级变速器两种，如果变速器挡位多其动力性和经济性得到保证，挡位少其操纵方便，本次设计我设计的是轻型载货汽车变速器，本次设计中我对其传动比作了仔细的分析计算并参考相关车型最终确定了各挡的传动比，针对变速器的传动机构方案的布置作了详细的分析最终选用4+1挡中间轴式变速器，换挡形式采用同步器换挡。结合总体的要求操纵机构形式选用直接操纵机构形式。本次设计的变速器即满足了汽车必要的动力性也满足了其经济性的指标。最后通过对齿轮、轴、键、轴承等的校核，其变速器的尺寸及其部件的强度都满足设计要求。

KD1060 TRUCK DESIGN
(THE GENERAL DESIGHN OF TRANSMISSION)
ABSTRACT
The car was born; the development of car, in history has left us drops. Since the last century car since birth, had already passed over one hundred years of storms. Karl Benz made from the first three-wheeled car 18 kilometers per hour speed, run to now, actually born from zero speed to accelerate to 100 km/h just need three seconds more super car. These one hundred years, automobile development speed is so amazing! At the same time, the auto industry also made many giants, they started a gm, ford, Toyota, Honda that some countries in economy important famous company. This article information written many interesting stories in China has become the world's auto power, let us look up a car, the development history of the cars bring us all sorts of joy and dream...
Transmission as an important component of car is used to change the engine reached the powerwheele’s torque and rotational speed, in order to get different power and speed in start, climbing, turning, accelerating, and other case of travel.
Transmission has two styles of mechanical manual transmission and mechanical devices continues transmission, if the transmission’s shift more its power and economic was guaranteed, if fewer its manipulation is convenience, this design I design an light truck transmission, this design I determined the speed ratio after careful analys of speed ratio and ultimately the relevant type of the car, I made a careful analysis of the layout of the drive agency programmers against the transmission and finally use the 4+1 block intermediate transmission, the form of shift use a synchronous device. After requested the overall the form of agencies use direct manipulation institutional forms. This designed of transmission meet the dynamic of the necessary power also meet its economic targets. Final adoption the degree of gear, axle, keys, bearings, etc. the size of transmission and strength of components are designed to meet the requirements.
