Abstract

A drive train is disclosed that includes an engine operable in a first engine operating state and a second engine operating state and a torsional-vibration damping system operatively connected to the engine. The torsional-vibration damping system includes a first torsional-vibration damper having a primary inertial mass and a secondary inertial mass, a second torsional-vibration damper, a first centrifugal pendulum arranged on the secondary inertial mass of the first torsional-vibration damper, and a second centrifugal pendulum arranged on the second torsional-vibration damper.
