Alternator Belt
The alternator belt is a belt that transfers the rotational energy of the engine to the alternator. The belt wraps around a pulley connected to the crankshaft. As the engine starts and the crankshaft rotates, the belt moves and transfers rotational energy to the alternator. The alternator, which is a type of generator, converts this energy into electricity to charge the battery and supply electrical power to various parts of the vehicle.
Although the main function of the alternator belt, as its name suggests, is to transfer the engine's rotational power to the alternator, in modern vehicles, both the timing belt and the alternator belt also serve to drive other engine components such as the water pump, hydraulic pump, oil pump, air conditioning compressor, and more.
