belt that goes around alternator

The function of the power steering pump drive belt is relatively straightforward but critically important. As the engine runs, the crankshaft spins, turning the drive belt. The belt then transfers this rotational force to the power steering pump, enabling it to perform its function of pressurizing the hydraulic fluid. The most common type of drive belt used in modern vehicles is the serpentine belt. This single, continuous belt may also drive other accessories such as the alternator, air conditioning compressor, and water pump. In older vehicles, separate V-belts were used, but today’s serpentine systems have largely replaced them due to their efficiency and ease of maintenance.

Ribbed belts feature a flat design that incorporates a series of longitudinal grooves or ribs. This design is not just aesthetically pleasing but serves multiple functional purposes. The grooves increase the belt's grip on the pulleys while reducing slippage, which in turn enhances the transfer of power. Moreover, the ribbed structure allows for flexibility and improved engagement with pulley systems, enabling quieter and smoother operation.
