089001-WG ABSTRACT OF THE DISCLOSURE A double clutch arrangement for use in a transmission (10) or other place where a mechanical clutch is desired that has a high torque capacity and small engagement and disengagement forces at the shift lever. The clutch arrangement is utilized on the output shaft (25) of a two-position clutch having forward and reverse gears (31,32) and includes a ball screw actuated clutch mechanism (35,36,37,38,39,45) positioned between the shaft and an externally actuated encompassing shift collar (38)in combination with a friction clutch mechanism. The friction clutch mechanism comprises either a pair of clutch friction packs (49,51) positioned between the shift collar (38) and the forward (31) and reverse (32) gears or a pair of cone clutches (82,83,84,85) therebetween. Initial actuation of the forward or reverse friction pack or cone clutch will initiate the ball screw clutch mechanism to lock up the clutch in either direction.
