motorcycle belt

A serpentine belt is a long, continuous belt that is used to drive multiple peripherals in an engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. The term serpentine refers to the belt’s winding path through various pulleys. A double-sided serpentine belt, as the name suggests, has grooves on both sides, allowing it to grip the pulleys more effectively. This design enables it to drive multiple accessories on either side of the belt.

The primary function of a car belt pulley is to guide and support the serpentine belt or timing belt, which wraps around the pulleys to drive multiple components of the engine. In essence, the pulley acts as a wheel or lever that helps facilitate the smooth operation of the belt. As the engine runs, the crankshaft turns, driving the belts, which, in turn, rotate the pulleys. This mechanical action enables the powered accessories to function, ensuring a vehicle can operate effectively without overheating or experiencing electrical failures.
