Abstract
A torque limiting coupling () in a drive line for driving agricultural implements has a coupling hub () and a coupling sleeve () that rotatably arranged around the coupling hub (). The coupling hub () and the coupling sleeve () are rotatable around a rotational axis D. Drivers () are displaceable in the coupling hub (), respectively, along a driver axis M that is transverse to the rotational axis D. The driversmove between a torque transmitting position and a switched-off position. Recesses () are formed in an inner circumferential face () of the coupling sleeve (). The drivers () engage the recessesin their torque transmitting position. A setting mechanism () acts upon the drivers () with a force to urge the driversto take up their torque transmitting position. The drivers () have, respectively, two ratchet faces (). The recesses () have, respectively, two counter ratchet faces (). When the coupling () is switched-off in each rotational direction of the coupling hub () relative to the coupling sleeve (), with a number of relative revolutions in excess of a re-switching-on number of revolutions, one ratchet face () and a counter ratchet face () interact such, that a displacement of the drivers () into the torque transmitting position is prevented.
