Abstract: A torque limiting coupling rotatably arranged around a longitudinal axis A has a coupling hub (2, 102, 202), drivers (6, 106), a coupling sleeve (3, 103, 203) and a switching disk (4, 104, 204). The switching disk (4, 104, 204) is rotatably arranged between a switched-on position and an idling position relative to the coupling hub (2, 102, 202). The drivers (6, 106) engage the coupling sleeve first recesses (7, 107,207) in the switched-on position. The drivers (6, 106) engage the switching disk second recesses (8, 108, 208) in the idling position. A first spring mechanism (25, 125, 225) urges the switching disk (4, 104, 204) in the direction towards the switched-on position. A second spring mechanism (12, 112, 212) acts axially on the switching disk (4, 104, 204) and urges the drivers (6, 106) against the coupling sleeve (3, 103, 203).

Abstract: A torque limiting coupling has a coupling hub (2) with circumferentially distributed apertures (5). Driving members (6) are adjustably held in the apertures (5). A coupling sleeve (3) includes first recesses (7). A switching disk (4) is rotatably arranged between a coupling position and an uncoupling position. The switching disk (4) is loaded towards the coupling position and loads the driving members (6) towards the coupling hub (2). The driving members (6), for torque transmitting purposes, engage the first recesses (7). When a torque limit is exceeded, the driving members (6) are transferred into the uncoupling position. Here, second recesses (8) are engaged by the driving members (6) in the uncoupling position. A locking means (28) is adjustable between a locking position, where the switching disk (4) is locked in its uncoupling position, and a disengaging position.

Abstract: A torque limiting coupling for a driveline for driving agricultural implements has a coupling hub (7) with first recesses (14) which receive adjustable driving members (17). The coupling hub (7) further includes second recesses (15) which include a spring assembly (30). Switching cams (27) of the spring assembly (30) load the associated driving member (17). A coupling sleeve (32) is arranged around the coupling hub (7). Covers (37, 38) laterally seal the unit and laterally guide the coupling hub (7). Sealing rings (47, 48) are provided to render the unit oil-proof. Oil at least partially fills the free space between the components. Thus, the unit ensures in the case overloading occurs, the driving members (17), which engage a groove (34) in the torque transmitting position, cannot return into the groove (34) until a relatively low rotational speed has occurred.
