<p>The invention relates to a clutch for coupling two shaft sections (2a, 2b) of a drive shaft. Said shaft sections (2a, b) carry an internal clutch ring (8) and an external clutch ring (9) which is coplanar to said internal ring. Said clutch rings (8, 9) are provided with notches (19) in the area of the circumferential surfaces facing one another. Said notches interact to give bores (20) in which the hydraulically displaced clutch bolts (22) engage. Said clutch bolts are mounted on a common servo-piston (23). The aim of the invention is to obtain a high operational reliability and user friendliness of the clutch. To this end, a supporting ring (26) is arranged on the side of the clutch rings (8, 9) opposite the clutch bolts (22) which bridges the distance (21) between them. Tension bolts (27) which are arranged off-set from the clutch bolts (22) protrude from said supporting ring. Said tension bolts can be extended by a second servo-piston (33) and carry a locking collar (28) which is allocated to the clutch bolts (22). The invention is also characterized in that the two servo-pistons (23, 33) are arranged in a housing (11) which is linked to a shaft section (2a) and which is held from behind by the locking collar (28).</p> |
