Hydrodynamic torque converter having converter lock-up clutch

A hydrodynamic torque converter, comprising:

• a converter housing formed by first and second housing shells that axially overlap and are connected to one another;
• a converter torus having a pump impeller and a turbine wheel driven hydrodynamically by the pump impeller by a converter fluid, wherein the first housing shell forms an impeller shell of the pump impeller;
• a torsional vibration damper including an input part attached to the turbine wheel;
• and
• a converter lock-up clutch connected between the pump impeller and the turbine wheel by pressure loading of the converter fluid, the converter lock-up clutch being further arranged radially between an outer circumference of the converter housing and the converter torus, wherein the turbine wheel includes a turbine wheel friction disc configured to be prestressed axially between a pressure-loaded annular piston and a mating friction surface of the first housing shell of the converter housing located radially outside the converter torus;
• wherein the converter lock-up clutch further comprises:
• a plurality of friction discs disposed axially between the pressure-loaded annular piston and the turbine wheel friction disc;
• and
• an inner multiple disc carrier attached to the turbine wheel, wherein at least one of the plurality of friction discs is hooked into the inner multiple disc carrier in a non-rotatable manner;
• wherein the input part forms the inner multiple disc carrier.
