Patent ID: 7081057

Claim:
A driven pulley system for use in a torque converter of a vehicle, the driven pulley system comprising a motion-transmitting fixed unit arranged to be fixed to a rotatable output shaft of the vehicle for rotation therewith to transmit motion between the output shaft and a belt included in the torque converter, the fixed unit including a fixed flange and a removable cam mounted to the fixed flange, and a belt-tensioning movable unit arranged for movement relative to the fixed unit to tension the belt, the movable unit including a movable flange and a cam follower, the fixed flange and the movable flange cooperating to receive the belt therebetween for engagement therewith, the cam follower being arranged to follow the cam to cause rotation of the movable flange relative to the fixed flange to tension the belt upon axial movement of the movable flange away from the fixed flange, and means for allowing detachment of the cam from the fixed flange to remove the cam from the driven pulley system while maintaining the cooperation of the fixed and movable flanges to receive the belt therebetween for engagement therewith.
