Automobile transmission, is used to coordinate the speed of the engine and the wheels of the actual speed of the transmission device, used to play the best performance of engine. The transmission can be in the running process of the automobile, the engine between the wheel and produce different transmission ratio, by shifting can make the engine work in the best state of dynamic performance. The transmission is the development trend of plex, increasingly high degree of automation, automatic transmission will be the mainstream of future. The transmission can be in the running process of the automobile, the engine between the wheel and produce different transmission ratio, by shifting can make the engine work in the best state of dynamic performance.
