ABSTRACT:
A coupling between a continuously rotating input shaft and a selectively rotatable output shaft has a friction type transition clutch operative to accelerate the output shaft to synchronous speed and to permit controlled deceleration of the output shaft to rest and a spline type direct clutch parallel to the transition clutch engageable at synchronous speed to directly couple the input and output shafts. The spline clutch includes an input member having an input spline with a pressure face at a first helix angle, an output member having an output spline with a pressure face at a second, smaller helix angle, and a longitudinally shiftable intermediate member having a spline with a first pressure face at the first helix angle and a second pressure face at the second helix angle. The difference in helix angles effects circumferential separation between the output spline pressure face and the intermediate member spline second pressure face before the two splines separate longitudinally.
