timing belt design

The primary function of the V-belt is to transmit rotational motion from the engine to attached components. When the engine runs, the crankshaft spins, causing the V-belt to turn. This motion transfers power to the connected accessories, allowing them to perform their designated roles. For instance, the alternator relies on the V-belt to generate electricity for the vehicle’s electrical system, while the power steering pump uses it to facilitate smoother steering.

The fan belt, also known as the serpentine belt, is a looped strip that drives various peripheral devices in an engine. In MAN trucks, the fan belt connects the engine's crankshaft to the cooling system's fan, helping to regulate engine temperature by facilitating airflow over the radiator. It also powers components like the alternator, power steering pump, and air conditioning compressor, indicating that a well-functioning fan belt is essential for maintaining the operational efficiency of the entire vehicle.
