Abstract

The invention relates to a hydrodynamic torque converter including a turbine wheel arranged inside of a housing, a torque converter lockup clutch, an axially mounted piston, a torsional vibration damper and a hub. The turbine wheel and the piston are rotationally fixed to the input component of the damper. The input component is connected to the hub by means of a connection provided with a circumferential backlash. The output component of the damper is connected to the hub without circumferential backlash.
