Abstract
A claw clutch (42) is added in line to a multiple-disc clutch 40. One actuating member 21 engages first the claw clutch 42 and then, almost simultaneously, the multiple-disc clutch 40. Return springs 37 disengage first the multiple-disc clutch 40 and then, almost simultaneously, the claw clutch 40. The multiple-disc clutch 40 can be engaged under full power. A dangerous drag moment of the multiple-disc clutch 40 is active only for a very short time when the clutch system is just being disengaged, immediately thereafter only the harmless redidual moment of the claw clutch 42 remains active.
