ABSTRACT:
A hydrodynamic torque converter with a converter circuit having at least an impeller wheel, a turbine wheel with a turbine hub, and a stator wheel, which together enclose an inner torus. A torsional vibration damper arranged within the inner torus is operably connected with a control disk that is connected with a driven shaft so as to be fixed with respect to rotation relative to it. The torque converter is further constructed with a lockup clutch by which can transmit a torque provided by a drive while bypassing the converter circuit. A controlling system for the torsional vibration damper is provided on the drive side of the turbine wheel and the control disk which has a driven-side controller for the torsional vibration damper, is arranged so as to be fixed with respect to rotation relative to the turbine hub but rotatable relative to the turbine wheel. The turbine hub is connected with the driven shaft guided in the converter housing such that the turbine hub is fixed with respect to rotation relative to the driven shaft.
