Core Functions

• Power Transmission: Transmits rotational power from the crankshaft to engine accessories through the drive belt. This enables accessories like the alternator to generate electricity, the power steering pump to assist in steering, and the air conditioning compressor to operate, ensuring the proper functioning of various vehicle systems.
• Vibration Damping: Incorporates damping elements to reduce torsional vibrations from the crankshaft. This helps minimize stress on accessory components and the drive belt, reducing noise and extending their service life.
• Belt Alignment and Tension Maintenance: Maintains proper alignment and tension of the drive belt. Correct belt alignment prevents premature wear and slipping, while appropriate tension ensures efficient power transmission without slippage, which is essential for the optimal performance of driven accessories.
