Abstract

A hydrodynamic torque converter device comprising a torsional vibration damper, an impeller, a turbine, a stator, and a converter lockup clutch. The torsional vibration damper has first and second energy accumulating devices with one or more first energy accumulators, and second energy accumulators, respectively. The converter lockup clutch and the first and second energy accumulating devices are connected in series. The turbine has an outer shell that is rotationally fixed to an intermediate part between the first and second accumulating devices. An input element of the first energy accumulating device is used to transmit torque via the lockup clutch for loading the first energy accumulating device. The input element of the first energy accumulating device has at least one lug having a free end and a non-free end, with the non-free end of the lug radially inside the free end of the lug.
