变速器作为传动系的主要组成部分,适应于汽车不同变化的行驶条件,并与发动机更好地配合,使汽车具有良好的动力性和经济性。通过驾驶员改变挡位的操作,使得汽车起步、加速和上坡行驶时驱动轮得到不同的驱动力。变速器分为有级变速器和无级变速器2种。由于考虑到制造成本以及维修
Transmission as the main component of the drive train to adapt to the changing conditions of the car driving and better with the engine, so that the car has good power and economy. Through the driver to change the gear operation, making the car start, accelerate and drive uphill when the driving wheel to get different driving force. Transmission is divided into a step-variable transmission and CVT 2 kinds. Due to manufacturing costs and maintenance considerations
