  • Patent number: 11808335
    Abstract: A hydrodynamic torque converter is provided with a converter housing and a converter torus with a pump impeller, a turbine wheel which is driven hydrodynamically by the pump impeller by a converter fluid. In order to bridge the 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. In order to provide the converter lock-up clutch with an increased transmission capacity, the turbine wheel is assigned at least one friction disc which can be prestressed axially between a pressure-loaded annular piston, 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.
