Torsional Vibration Damper and Hydrodynamic Torque Converter Device for an Automotive Drive Train

A hydrodynamic torque converter device for a motor vehicle drive train, the hydrodynamic torque converter device comprising:

• a torsion vibration damper having a first energy accumulator means, the first energy accumulator means including at least one first energy accumulator;
• a converter torus having a pump shell, a turbine shell, and a stator shell;
• a converter lockup clutch;
• at least one first wall arranged to radially support the at least one first energy accumulator;
• and,
• at least one roller element means comprising at least one roller element, the at least one roller element means being arranged between the at least one first energy accumulator and the least one first wall, and operatively arranged to provide low friction support of the at least one first energy accumulator at the at least one first wall.
