Abstract

A torsional vibration damper for a lockup clutch of a hydrodynamic clutch device has a drive-side damper element which is in an operative connection with a turbine shell and a driven-side damper element which is connected with the drive-side damper element via a damping device having at least one energy accumulator acting in the circumferential direction and is in a working connection with a turbine hub. The drive-side damper element is constructed as a planetary carrier for at least one gear unit element of a planetary gear set, while the driven-side damper element acts as another gear unit element of the planetary gear set.
