ABSTRACT:
A torsional vibration damper for arrangement in a drive train of an automobile comprises three flywheel mass arrangements arranged so as to be rotatable both jointly and relative to one another about a common first axis of rotation. At least two of the three flywheel mass arrangements are torsionally elastically coupled to one another by a spring arrangement. The three flywheel mass arrangements are coupled to one another via a roller gear. The first flywheel mass arrangement has a first toothing along at least a part circumference and the third flywheel mass arrangement has a second toothing along at least a part circumference. The second flywheel mass arrangement has at least one roller carrier mounted so as to be rotatable about a second axis of rotation and a plurality of roller bodies which roll on part regions of the first toothing and on part regions of the second toothing. Each roller body is arranged at a distance from the second axis of rotation and is mounted rotatably mounted on the roller carrier for rotating about a third axis of rotation assigned to the particular roller body.
