Clutch

The invention relates to a clutch ( 2 ), especially for motor vehicles, for the torque connection of at least two drive parts which are rotatable about a rotational axis ( 4 ), comprising at least one clutch device ( 6 ) with a first clutch body ( 8 ) with at least one first clutch surface ( 12 ) and a second clutch body ( 10 ) with at least one second clutch surface ( 14 ), with said first and second clutch body ( 8, 10 ) being coaxially displaceable relative to each other by means of an actuating means ( 24 ) and said first and second clutch surface ( 12, 14 ) being mutually connectable in a non-positive way in at least one clutch engagement position, with the actuating means ( 24 ) comprising at least one ring gear ( 26 ) which comprises a ramp mechanism ( 28 ) and is twistable about the rotational axis ( 4 ) by an actuator ( 40 ), which mechanism, in the clutch engagement position, presses the first clutch body ( 8 ) against the second clutch body ( 10 ). The actuator ( 40 ) acts substantially in a tangential direction on the ring gear ( 26 ) via a linear motor ( 46 ), a worm gear ( 54 ) or a gearshift rod ( 58 ).
