Abstract: The present invention relates to a multiple clutch device having a first clutch which is assigned a first actuating piston with a first pressure chamber and a first pressure equalization chamber, and having a second clutch which is assigned a second actuating piston with a second pressure chamber and a second pressure equalization chamber, a first crossflow channel being provided for setting the hydraulic fluid column in the first pressure equalization chamber and a second crossflow channel being provided for setting the hydraulic fluid column in the second pressure equalization chamber. According to the invention, the first and second crossflow channels are arranged in such a way that both the oil which is discharged via the first crossflow channel and the oil which is discharged via the second crossflow channel can be fed to the first and second clutches.

Abstract: The present invention relates to a frictional device (6) comprising at least one friction plate (2), which has a plate-side toothing system (14), and a plate carrier (4), which has a carrier-side toothing system (70) and a predefined fitting end (66) for fitting the friction plate (2), the contours (62, 72) of the toothing systems (14, 70) corresponding to one another in such a way that the friction plate (2) can be brought into engagement with the plate carrier (4), forming a rotational drive connection. The friction plate (2) here has a first axial direction (16) and an opposing second axial direction (18). According to the invention the contours (62, 72) of the toothing systems (14, 70) are formed in such a way that only in the first axial direction (16) can the friction plate (2) be brought into engagement with the plate carrier (4) via the predefined fitting end (66) of the plate carrier (4).

Abstract: The invention relates to a device for axially positioning a clutch device, especially a dual-clutch device, on a rotary drive, wherein the clutch device is mounted so as to rotate about a rotational axis of said rotary drive. A retaining nut is coaxially screwed with the rotary drive, and the clutch device is indirectly or directly supported on said nut in an axial direction.
