The invention relates to a torsional vibration damper (1) which is a part of a coupling device (4) that can be used to produce a functional connection between a drive (2) and a driven end (3), and that comprises a coupling system (5) which has a coupling element (6) able to be displaced between an engagement position in which a functional connection between the drive and the driven end can be produced, and a release position in which this functional connection is disconnected, as well as at least two damping devices (7, 8) which are arranged to be radially offset to one another and with which at least one vibration absorption system (9) acting between the two damping devices, and at least one additional mass (10) independent of said vibration absorption system, are associated. The coupling element is functionally connected to the input (11) of one of the damping devices, an output (14) of another of the damping devices is functionally connected to the driven end, and the output (12) of one of the damping devices is functionally connected to an input (13) of another of the damping devices by means of a connection device (15) which comprises at least one vibration absorption mass carrier (16) for receiving at least one vibration absorption mass (17) of said vibration absorption system. The coupling element is functionally connected to the input of the radially inner damping device, the output of the radially outer damping device is functionally connected to the driven end by means of the additional mass, while the output of the radially inner damping device is functionally connected to the input of the radially outer damping device by means of said connection device such that the additional mass and the connection device are able to move relative to one another. |
