The front end of the crankshaft carries three devices. the gear or sprocket that drives the camshaft, the vibration damper. and the fan belt pulley.
在曲轴的前端有三个装置：驱动凸轮轴的齿轮或链轮、减震器和风扇皮带轮。

Water pump and cooling fan of traditional cars are usually driven by the engine through V belt, which is intertwined between crankshaft pulley and water pump pulley. Therefore, the rotational speed of water pump is in proportional relationship with the engine speed.
而传统汽车的水泵和散热风扇一般由发动机曲轴通过V带传动，传动带环绕在曲轴带轮与水泵带轮之间，因此水泵转速与发动机转速成比例关系。
