• 1. Power transmission core: As the front-end power distribution hub of the engine, it can efficiently transmit the rotational power of the crankshaft to accessories such as the generator and air conditioning compressor, ensuring the operation of the vehicle's electricity and comfort system.
• 2. Buffer and shock absorption: Most integrated torsional shock absorbers can absorb the torsional vibration generated by crankshaft operation, reduce the impact on accessories, and extend the life of the transmission system.
• 3. Ensure smooth operation: Precise dynamic balance design, combined with belt tensioning mechanism, ensures that the belt transmission does not slip or deviate, and maintains stable operation of accessories.
• Compact and efficient structure: adopting a pulley structure to achieve multi accessory drive with a small volume, high space utilization, and better transmission efficiency than forms such as chains.
• Cost and maintenance advantages: The manufacturing process is mature, the cost is low, and the belt transmission noise is small. In the later stage, only regular belt replacement is needed, making maintenance convenient.
