Abstract (en)
[origin: WO2007054061A2] The invention relates to a hydrodynamic torque converter device for an automotive drive train, comprising a torsional vibration damper, a converter torus which is configured by an impeller, a turbine wheel and a stator, and a converter lockup clutch. The torsional vibration damper has a first energy accumulating device with one ore more first energy accumulators, and a second energy accumulating device with one ore more second energy accumulators. The converter lockup clutch, the first energy accumulating device and the second energy accumulating device are connected in series. At least one intermediate part is interposed between the first and the second energy accumulating device and is connected to the two energy accumulating devices in series. The turbine wheel has an outer turbine shell that is connected to the intermediate part in a rotationally fixed manner or forms the same, an input element of the first energy accumulating device being used to transmit via the converter lockup clutch a torque for loading the first energy accumulating device when the converter lockup clutch is closed. The input element of the first energy accumulating device, for the purpose of loading a respective front of a respective first energy accumulator, has at least one respective lug with a free end and a non-free end. The respective non-free end of a respective lug is positioned in relation to the radial direction of the rotational axis of the torsional vibration damper radially inside the free end of the respective lug.
