The invention is directed to a multiple-clutch device, such as a double-clutch device, for arranging in a drivetrain of a motor vehicle between a drive unit and a transmission, wherein the clutch device has a first clutch arrangement associated with a first transmission input shaft of the transmission and a second clutch arrangement associated with a second transmission input shaft of the transmission for transmitting torque between the drive unit and the transmission. It is suggested that a bearing arrangement is associated with at least one of the clutch arrangements, wherein the latter is supported or can be supported so as to be relatively rotatable by means of the bearing arrangement on at least one of the transmission input shafts, at least one of which is constructed as a hollow shaft and a shaft constructed as a hollow shaft encloses the other shaft, preferably at least at the radial outer transmission input shaft which is constructed as a hollow shaft.
Multiple-clutch device, for installation in a drivetrain of a motor vehicle between a drive unit and a transmission, comprising a first clutch arrangement associated with a first transmission input shaft of the transmission, and a second clutch arrangement associated with a second transmission, input shaft of the transmission for transmitting torque between the drive unit and the transmission, at least one of the transmission input shafts being constructed as a hollow shaft, another of the transmission input shafts extending through said one input shaft, in which at least one of the clutch arrangements is supported by a bearing arrangement on one of said at least one and said other of said transmission input shafts, so as to be rotatable relative to it, the clutch arrangements having a common tubular, ring part by which said clutch arrangements are mounted to the transmission input shafts, an input side of each of the respective clutch arrangements being connected with the ring part so as to be fixed with respect to rotation relative to it and so that a torque flow from the drive unit to an input side of one clutch arrangement runs via an input side of another of the clutch arrangements and via the ring part.
