Abstract
A torsional vibration damper assembly for a hydrodynamic coupling device, in particular a torque converter, comprises a primary side having a plurality of cover disk elements, a secondary side which is rotatable with respect to the primary side about an axis of rotation against the action of a plurality of damper springs, a central disk element engaging between the cover disk elements, and a turbine wheel having a turbine wheel shell. The plurality of cover disk elements are fixedly connected to one another on the radial outer side of the damper springs, and a cover disk element located directly adjacent to the turbine wheel shell is fixedly connected to the turbine wheel shell on the radial inner side of the damper springs by connection elements of a first set of connection elements. The connection elements of the first set of connection elements do not produce a fixed connection between the cover disk elements on the radial inner side of the damper springs.
