摘要： 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.

摘要： An accessory drive tuning device with a torsion spring for angular vibration isolation and having a spring pocket that frictionally engages the end of the torsion spring. The engagement may be with a wedge-shape on either the spring end or the pocket or both, adapted so that the spring end wedges into the pocket. The engagement may be by interference fit. One or both ends of the spring may be engaged in respective pockets.
