Abstract
A torsional vibration damper, especially for transmission of torque in a hydrodynamic torque converter, includes a primary side, a secondary side, and a plurality of damper spring arrangements arranged between the primary side and the secondary side such that the primary side is rotatable relative to the secondary side against an urgency of the damper spring arrangement. Each damper spring arrangement has at least one spring and is supported in each circumferential end area at a supporting area of the secondary side and at a first and a second supporting area of the primary side which are arranged on both axial sides of the associated supporting area of the secondary side. The primary side has a substantially annular carrier part and at least one of the first and second supporting areas of the primary side are constructed as separate parts that are connected for rotation with the primary side.
