Abstract: A clutch device including a housing connected to a drive for rotation in common around an axis of rotation and fillable with a fluid; first friction elements connected to the housing by a first friction element carrier for rotation in common around the axis of rotation; second friction elements connected to a takeoff by a second friction element carrier for rotation in common around the axis of rotation; a piston element configured to exert a force so that the first and second friction elements frictionally engage each other; an abutment arrangement arranged on the first or second friction element carrier, the abutment arrangement providing a support for the first and second friction elements; and an elastic arrangement disposed in a path of force transmission between the piston element and the abutment arrangement and axially compressible when the piston element exerts the force on the first and second friction elements.

Abstract: A friction disk for a wet-running clutch for a motor vehicle includes a lining carrier ring, provided with connecting areas for connecting the friction disk to a drive side or to a takeoff side of a clutch, and a plurality of friction lining elements, carried on at least one side of the lining carrier ring, Fluid flow channels are provided between the friction lining elements which are directly adjacent to each other in the circumferential direction, wherein at least some of the fluid flow channels have different channel widths.

Abstract: A clutch device has a housing connected to a drive; a takeoff, which is mounted with freedom of rotation in the circumferential direction relative to the housing; and at least one friction clutch, which is mounted in the housing and which can be shifted between an engaged position and a released position. The clutch has clutch components including at least one pressure-exerting device and at least one clutch element which can be actuated by the pressure-exerting device, both the clutch element and the pressure-exerting device being able to shift position to a limited extent in the axial direction. The clutch element has at least one friction surface and a clutch hub in working connection with the takeoff.

Abstract: A clutch apparatus includes a drive; a housing connected to the drive for rotation in common; a takeoff which can rotate relative to the housing, the takeoff having an axial stop; and a takeoff hub connected to the takeoff for rotation in common, the takeoff hub having an axial stop element and being axially movable relative to the takeoff. A friction clutch mounted in the housing and includes at least one first clutch element connected to the housing for rotation in common, at least one second clutch element connected to the takeoff hub for rotation in common, and means for exerting pressure to shift the clutch from a first position to a second position, wherein the first and second clutch elements are frictionally engaged in one of the positions and disengaged in the other of the positions. The stop element and the stop are separated by a gap A defining a maximum distance in the first position, the gap A being at least partially closed in the second position.
