Patent ID: 8479901

Claim:
A hydrodynamic torque converter ( 1 ) with: an impeller ( 2 ) connected on the drive side arranged in a housing ( 3 ); a turbine ( 4 ) driven by the impeller, connected with a driven side of the torque converter ( 1 ); a turbine damper ( 5 ) actively disposed between the turbine ( 4 ) and the driven side, wherein: the turbine damper ( 5 ) comprises: a first damper part ( 9 ) formed out of an input part ( 6 ) connected with the turbine ( 4 ) and an intermediate flange ( 11 ), the first damper part limitedly rotatable against the intermediate flange ( 11 ) by the action of at least a first energy accumulator ( 12 ); a second damper part ( 10 ) comprising the intermediate flange ( 11 ) and an output part ( 8 ) which is limitedly rotatable against the intermediate flange ( 11 ) by the action of at least a second energy accumulator ( 13 ); and an adaptive-speed vibration absorber ( 16 ) arranged on the intermediate flange ( 11 ), wherein the adaptive-speed vibration absorber is tuned to provide compensating vibration absorption for inherent frequencies and mode shapes of the intermediate flange.
