Abstract

A hydrodynamic torque converter with an impeller connected on the drive side arranged in housing and a turbine driven by the latter, connected with the driven side of the torque converter, with a turbine damper actively disposed between the turbine and driven side. To improve the vibration damping on the driven side of the torque converter, the turbine damper with a first damper part is formed out of an input part connected with the turbine and an intermediate flange, limited and rotatable opposite and against the action of at least a first energy accumulator and a second damper part with the intermediate flange and an output part limited and rotatable oppositely and against the action of at least a second energy accumulator. An adaptive-speed vibration absorber is arranged on the intermediate flange.
