Torsional Vibration Damping Arrangement, Particularly For the Power Train of A Vehicle

A torsional vibration damper arrangement, comprising:

• a damper spring arrangement;
• a primary side of the torsional vibration damper, one side of the primary side comprises a first cover disk element;
• a secondary side of the torsional vibration damper that is rotatable with respect to the primary side around an axis of rotation against the action of the damper spring arrangement, one side of the secondary side comprises a second cover disk element;
• a central disk element arranged between the cover disk elements on an other side of the primary side and secondary side;
• a plurality of first connection elements configured to connect the cover disk elements to one another radially inside the damper spring arrangement to be fixed axially and to transmit torque;
• and
• a plurality of second connection elements configured to connect the cover disk elements to one another such that they are prevented from moving axially away from one another,
• wherein substantially no torque is transmitted between the cover disk elements by the plural second connection elements.
