Abstract
A coupling (1) which is disconnectable in the driving direction of rotation has a coupling hub (2) and a coupling sleeve (3) rotatably arranged thereon. The hub (2) and sleeve (3) are connected in the driving direction of rotation by at least one locking ratchet (9, 10) and locking ratchet recess (7, 8 and 13, 14) respectively of the coupling hub (2) and the coupling sleeve (3), a locking pin (19, 20) with its longitudinal side (23, 24) extending in a tangential transverse bore (21, 22) presses the locking ratchets (9, 10) out of the locking ratchet recess (13, 14) in the coupling sleeve (3) when a switching ratchet (36) causes the rotation of the switching ring (4) by means of locking pins (19, 20).
