Abstract

A torsional vibration damper arrangement including a torsional vibration damper with a primary side and a secondary side rotatable with respect to the primary side around an axis of rotation against the action of a damper spring arrangement. One side of the primary side and secondary side includes two cover disk elements and a central disk element arranged between the cover disk elements. The cover disk elements are connected to one another by first connection elements radially inside the damper spring arrangement so as to be fixed axially and so as to transmit torque. The cover disk elements are connected to one another by second connection elements in such a way that they are prevented from moving axially away from one another. No torque can be transmitted between the cover disk elements by the second connection elements.
