1. A hydrodynamic torque converter comprising a converter housing and a converter torus having a pump impeller, a turbine wheel driven hydrodynamically by the pump impeller by a converter fluid, wherein, in order to bridge a hydrodynamic drive, a converter lock-up clutch which is connected between the pump impeller and the turbine wheel by pressure loading of the converter fluid is arranged radially between an outer circumference of the converter housing and the converter torus, wherein the turbine wheel is assigned a turbine friction disc which can be prestressed axially between a pressure-loaded annular piston, which is provided with a friction lining and which is hooked in an axially movable manner into the converter housing, and a mating friction surface of a converter housing section radially outside the converter torus, wherein an inner multiple disc carrier is attached to the turbine wheel, and at least one inner friction disc is hooked into the inner multiple disc carrier in a non-rotatable manner, wherein an input part of a torsional vibration damper is attached to the turbine wheel.
