Abstract: A vibration damper includes an input side and output side, one or more elastic elements for transmitting force between the input side and the output side, and a centrifugal force pendulum having a pendulum flange and one or more pendulum masses which are attached movably to the pendulum flange in the plane of rotation of the pendulum flange. It is proposed that certain ratios of masses and volumes of the elastic elements and of the pendulum masses be formed. If one or more of the ratios lie in specified ranges, then good damping or elimination of torsional vibrations by the vibration damper can be assumed.

Abstract: A friction clutch including an input side and an output side arranged to rotate, a fluid chamber fillable with a cooling liquid including a first friction partner, a second friction partner, an inner disc carrier coupled to one of the two friction partners radially on the outside, and a compression device having a pressure chamber fillable with a pressure fluid to provide axial compression of the friction partners to generate a torque-locking engagement between the input side and the output side. A deflection device is provided in the fluid chamber wherein the inner disc carrier includes at least one first passage for the cooling liquid to pass through, and the deflection device feeds back at least a first portion of the cooling liquid flowing in a radially outward direction between the friction partners into a radially inward direction to the first passage of the inner disc carrier.
