20100151979 | SWITCHABLE DRIVE PULLEY WITH ELECTRICALLY ACTUATED FRICTION DISC TORQUE TRANSFER MECHANISM - A switchable drive pulley system that allows driving engagement or disengagement of a pulley from the shaft of an accessory drive is provided. The pulley is mounted to the shaft by a bearing having an inner ring that rotates with the shaft and an outer ring that rotates with the pulley. A friction disk is arranged adjacent to the bearing inner ring and outer ring. When axial pressure is applied to the friction disk, relative motion between the inner and outer bearing rings is stopped, allowing the transfer of torque from the pulley to the shaft in order to drive the accessory drive, with the pulley and shaft rotating at the same speed. When pressure is removed from the friction disk, the pulley and the outer bearing ring can spin independently of the inner ring and shaft. The shaft can therefore remain stationery while the pulley continues to turn driven by the accessory belt drive. | 06-17-2010 |
