Abstract: A coupling, used in drivelines or for driving agricultural implements, has a first coupling element (1) and a second coupling element (2). An actuating element (4) is axially displaceable relative to the first coupling element (1) between a switched-on position and a switched-off position. A power drive (5) actively displaces the actuating element (4). The power drive (5) loads the actuating element (4) in the switched-on position against an abutment mechanism (31, 36). A first spring (6), in the switched-on position of the actuating element (4), loads the friction assembly (3). This enables the friction assembly (3) to assume the torque transmitting position.

Abstract: A coupling, used in drivelines or for driving agricultural implements, has a first coupling element (1) and a second coupling element (2). The coupling elements (1, 2) are arranged to be rotatable relative to one another around an axis of rotation Z. A friction assembly (3) can be loaded to transmit torque between the first coupling element (1) and the second coupling element (2) to assume a torque transmitting position. An actuating element (4) is axially displaceable relative to the first coupling element (1) between a switched-on position and a switched-off position. In the switched-on position, the friction assembly (3) is loaded to assume the torque transmitting position. A power drive (5) displaces the actuating element (4). The power drive (5) loads the actuating element (4) in the switched-on position against an abutment mechanism (31, 36). The abutment mechanism (31, 36) delimits the displacement path of the actuating element (4) and holds the actuating element (4) in the switched-on position.
