Abstract

A method for transmission of and damping of a mean torque with a superposed alternating torque in a torque transmission arrangement for a powertrain of a motor vehicle having an input and an output. The mean torque with the superposed alternating torque is transmitted along a torque path from the input the output. The input rotates at an input speed and the output rotates at an output speed. A slip arrangement is provided in the torque path between the input and the output for generating a speed slip. The slip arrangement provides a maximum of an external activation of the speed slip in the area of a maxima of at least one periodic oscillation component of an alternating component and provides a minimum of an external activation of the speed slip in the area of a minima of at least one periodic oscillation component of the alternating component (new).
