Abstract

The invention relates to hydrodynamic torque converter (1) comprising a turbine wheel (3) arranged inside of a housing (2), a torque converter lockup clutch (10), an axially mounted piston (6), a torsional vibration damper (20) and a hub (5). The turbine wheel (3) and the piston (6) are rotationally fixed to the input component (21) of said damper (20). The input component (21) is connected to the hub (5) by means of a connection (52) provided with circumferential backlash. The output component (22) of the damper (20) is connected to the hub (5) without circumferential backlash.
