Abstract
A hydrodynamic torque converter comprising a pump wheel and a turbine wheel mounted to be rotatable about an axis of rotation is disclosed. A fluid in a region between the pump wheel and the turbine wheel is provided wherein a first axial contact surface is formed on the pump wheel and a second axial contact surface is formed on the turbine wheel. A frictional connection between the pump wheel and the turbine wheel can be produced when the pump wheel and the turbine wheel are pressed axially against one another. Moreover, one of the contact surfaces is configured to be flexible in order to lie against the other contact surface under an axial pressure load.
