What is a car drive belt?

Automobile drive belt is an important part of the engine, it includes the timing belt (timing belt) used for the camshaft and crankshaft between the timing drive belt and used to drive the front of the engine auxiliary parts such as generator, steering booster pump, fan, water pump, supercharger and air conditioning compressor and other components of the V-shaped belt and multi-ribbed belt. 

Auto transmission belt of technical progress is closely related with the technical development of the engine, as people more and more high to the requirement of engine is lightweight, width and height of the engine is lower, the output power is rising, which requires the number of belt declining, the thickness of falling, and is able to transmit torque is increased. 

In this case, the V belt, poly V belt and synchronous belt has appeared, the manufacturing material of the belt in the continuous improvement,  EPDM (Ethylene Propylene Diene Monomer), and other new type of synthetic rubber materials continuously applied to the belt in the manufacture of in order to enhance strength, oil resistance and the reliability of the transmission belt and other technical indicators.
