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.

Torque converter

The invention relates to a centrifugal force pendulum () for suppressing torsional oscillations in a drive train, comprising a first and a second flange () that are non-rotatably connected to the drive train and a first and a second pendulum mass () that are arranged axially offset between the flanges. The pendulum masses have different suppressing frequencies.

Centrifugal force pendulum

A wet friction clutch comprising at least one clutch component which is rotatable around a shaft, wherein in the interior of the clutch component a rotary valve component that is rotatable around the shaft is formed which is deflectable by an angle of deflection in comparison to the rotatable clutch component by a relative rotation around the shaft, wherein the rotatable clutch component has at least one first opening and the rotary valve component has at least one second opening, wherein a total opening is released by an at least partial overlapping of the first opening and the second opening, the size of the total opening being dependent on the angle of deflection.
