Abstract
A multiple-clutch device, possibly a double-clutch device, for arranging in a drivetrain of a motor vehicle between a drive unit and a transmission. 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. The clutch arrangements are constructed as plate clutch arrangements, one of which has a greater effective friction radius than the other. Steps are taken to make the torque-transmitting capacity of the plate clutch arrangement with the smaller effective friction radius at least approximately equal to the torque-transmitting capacity of the plate clutch arrangement with the larger effective friction radius with respect to a reference input quantity, possibly a reference actuation pressure, which determines the strength of the frictional engagement of the plates and which is the same for both clutch arrangements.
