Abstract:
1. A multi-speed drive for driving an input shaft of a load, comprising: a first clutch system including an engagement clutch, a transfer member and a first overrunning clutch; a first clutch system input member that, when operatively connected to the input shaft by the first clutch system, drives the input shaft to rotate at a first speed, wherein the engagement clutch is positionable in a first position and in a second position, wherein in the first position the engagement clutch operatively connects the first clutch system input member to the transfer member, and wherein in the second position the engagement clutch operatively disconnects the first clutch system input member from the transfer member, wherein the first overrunning clutch is configured to permit the input shaft to rotate in a drive direction faster than the transfer member, and is configured to operatively connect the transfer member to the input shaft when the transfer member is rotating in the drive direction faster than the input shaft; wherein the transfer member is in radial relationship with the first overrunning clutch; a second clutch system including a second overrunning clutch; and a second clutch system input member that, when operatively connected to the input shaft through the second clutch system, drives the input shaft to rotate at a second speed that is slower than the first speed, wherein the second overrunning clutch is configured to permit the input shaft to rotate in the drive direction faster than the second clutch system input member, and is configured to operatively connect the second clutch system input member to the input shaft when the second clutch system input member is rotating in the drive direction faster than the input shaft.
