Abstract
A belt tuning device to an accessory belt drive system (ABDS) that utilizes a torsional spring to connect the belt pulley to the shaft of a motor generator unit to isolate the system and allow the pulley to advance ahead of the motor or to be behind the motor. The tuning device also has a free running zone providing a decoupling function for the system, allowing the tuning device to be both a driver and a generator of power. The tuning device has all of the belt pulley, a spring retainer, a torsion spring, a stop ring, and a shaft fixed in relation to each other.
