Abstract
The invention relates to a piston assembly for arrangement in a pressure cavity in a force transfer device for operating a first and a second actuatable clutch device, comprising a piston element associated respectively with an actuatable clutch device. The invention is characterized in that the piston element of the second clutch device is guided at the piston element of the first clutch device movable against a stop, forming an additional second cavity, loadable with pressure means, wherein the first piston element is movable in an axial direction, relative to the piston element of the second clutch device.
Claims18
A piston assembly (14) for arrangement in a pressure cavity (5) of a force transfer device (1) for operating a first and a second actuatable clutch device (3, 4), comprising a piston element (9, 10), associated respectively with said actuatable clutch device (3, 4), wherein said piston element (10) of said second clutch device (4) is guided at said piston element (9) of said first clutch device (3) movable against a stop (13), forming an additional second cavity (12), loadable with pressure means, wherein said first piston element (9) is movable in an axial direction, relative to said piston element (10) of said second clutch device (4).
A force transfer device (1), comprising two actuatable clutch devices (3, 4), disposed in the force flow between an input (E) and an output (A) in a first pressure cavity (5) with an associated actuation device, comprising at least one respective piston element (9, 10), wherein one of said actuatable clutch devices (3, 4) is supported in an axial direction at said piston element (9, 10) of said other clutch device (4, 3).
