Abstract (en)
[origin: WO2007054062A1] The invention relates to a torsional vibration damper (10) and a hydrodynamic torque converter device (1). Said device has a converter torus (18) which is configured by an impeller (12), a turbine wheel (14) and a stator (16), and a converter lockup clutch (20). The torsional vibration damper (10) has at least one first energy accumulating device (28) with one ore more first energy accumulators (68) (e.g. coil spring or bow spring), at least one first wall (92) radially supporting the at least one first energy accumulator (68). The invention is characterized in that a rolling body device (98) (e.g. a rolling gear) is interposed between the at least one first wall (92) and the at least first energy accumulator (68) (e.g. coil spring or bow spring).
