The primary function of a V-belt is to transmit power from one rotating shaft to another. When a motor turns a pulley connected to a V-belt, the belt transfers this motion to another pulley, often driving a connected machine, such as a fan, compressor, or conveyor. This design minimizes slippage, which is a common issue in flat belt systems. The wedging action of the V-belt into the pulley grooves allows for a tighter grip, which translates to better power transmission efficiency.

To understand the fan belt's role, we must first consider its basic function. The fan belt, also known as the serpentine belt in many modern trucks, connects various engine components to the crankshaft. Its primary purpose is to drive the vehicle’s cooling fan, which is essential for regulating the engine temperature. In addition, the fan belt powers other critical accessories, including the alternator, power steering pump, and air conditioning compressor. This multifunctionality underscores its importance in the overall operation of a truck.
