Abstract:
A clutch for coupling two shaft sections of a drive shaft, the shaft sections supporting an inner clutch ring and an outer clutch ring coplanar thereto, said clutch rings being provided with notches in the area of the facing circumferential surfaces, which in a congruent position complement one another to bores, into which hydraulically movable clutch bolts can be inserted which fixedly connect the clutch rings to one another for common rotation and can be actuated by a common annular servopiston, wherein on the side of the clutch rings opposite the clutch bolts a support ring, bridging a gap between the two clutch rings, is arranged from which tie rods, offset relative to the clutch bolts, project that can be extended by a second annular servopiston and cooperate with a locking ring correlated with the clutch bolts, and wherein the locking ring, when the tie rods are extended, can be moved from a position in which the clutch bolts are secured in their insertion position into a position for releasing the clutch bolts, and in that the two servopistons, which are hydraulically movable away from one another and toward one another, are arranged in an annular chamber of a housing connected to the shaft section and engaged from behind by the locking ring.
