附 录Auto transmission system will provide is to transfer the power of the engine, and so as to meet the needs of car form. In general the mechanical transmission in the car. A transmission can not completely solve the vehicle driving characteristics with the contradictions and structure required valve decorate on problems. First, because the vast majority of engine in the car is the longitudinal resettlement, in order to make its torque can drive wheels, must pass by around the main reducer drive to change the direction of transmission torque, through may still drive to solve the differential by starting to right and left the wheels of torque allocation problem. The second is the main task of the transmission by selecting the appropriate only in each file number and gear ratio, in order to make internal combustion engine torque - speed characteristics can adapt in all kinds of resistance to car under the dynamic requirements, but fish economy drive axle of the function of the main reducer lies in that when the transmission, the highest gear in cars had enough traction, appropriate maximum speed and good fuel economy. Therefore, it is required to transmission gearbox, will pass from the power, through the drive axle of the main reducer to further increase torque, reduce the speed of change. Accordingly, want to make auto transmission design is reasonable, first must choose good transmission ratio, and the total it properly allocated to the transmission and axles. The latter deceleration than than into primarily slowdown. When the transmission directly file in position, performance and fuel economy car than mainly dependent on the Lord slowdown. In a cars total layout design, should according to the working conditions and car engine, transmission, tires and other related parameters of the Lord, choosing the appropriate slowing the car with good board guarantee dynamic performance and fuel economy. Foreign some big car factory will often a certain type of automobile design has a variety of Lord deceleration than for selection and use of rising to meet the different needs of variant car and. Due to the improving, automobile engine power reduce weight and road conditions improved, than to have to reduce main slow development trend. The choice advocate deceleration than should consider when making car can meet high-speed request, and can in common speed range reduce engine speed, reducing fuel consumption, improve engine life and improve vibration and noise characteristics, etc.汽车传动系的总任务是传递发动机的动力，并使之适应于汽车形式的需要。在一般汽车的机械式传动中。有了变速器还不能完全解决发动机特性与汽车行驶要求阀的矛盾和结构布置上的问题。首先是因为绝大多数的发动机在汽车上是纵向安置的，为了使其扭矩能传给左右驱动车轮，必须由驱动桥的主减速器来改变扭矩的传递方向，通过时还得由驱动桥的差速器来解决左、右启动车轮的力矩分配问题。其次是因为变速器的主要任务仅在于通过选择适当的排挡数目及各档速比，以使内燃机的扭矩转速特性能适应汽车在各种阻力下对动力性鱼经济性的要求，而驱动桥主减速器的功用则在于当变速器处于最高档位时，使汽车有足够的牵引力、适当的最高车速和良好的燃料经济性。为此，则需将经过变速器，传动轴传来的动力，通过驱动桥的主减速器，进行进一步增大扭矩，降低转速的变化。因此，要想使汽车传动系设计得合理，首先必须选择好传动系的总速比，并恰当地把它分配给变速器和驱动桥。后者的减速比成为主减速比。当变速器在直接档位置时，汽车的动力性及燃料经济性主要决定于主减速比。在汽车的总布置设计时，应根据汽车的工作条件及发动机、传动系、轮胎等的有关参数，选择合适的主减速比来保证汽车具有良好的动力性和燃料经济性。国外一些大的汽车制造厂，
