DRIVE TRAIN

摘要

A drive train including an internal combustion engine having a predefined number of cylinders, and operable in a first engine operating state in which all cylinders are in operation, and a second operating state in which some of the cylinders are not in operation. The drive train has a torsional-vibration damping system with at least one torsional-vibration damper and at least one centrifugal-force pendulum. In order to improve the torsional-vibration behavior of the drive train, a centrifugal-force pendulum and optionally a torsional-vibration damper are adapted to control torsional-vibration behavior of the engine in one operating state, and a torsional-vibration damper and optionally a second centrifugal-force pendulum are adapted to control the torsional-vibration behavior of the engine in the other engine operating state.

1: A drive train comprising:
an internal combustion engine having a predefined number of cylinders and operable in a first engine operating state in which all the cylinders are in operation, and operable in a second engine operating state in which some of the cylinders are not in operation, a torsional-vibration damping system including at least one torsional-vibration damper and at least one centrifugal pendulum, wherein at least one of a centrifugal pendulum and a torsional-vibration damper is adapted to a control engine torsional-vibration behavior during the first engine operating state, and at least one of a torsional-vibration damper and a second centrifugal pendulum is adapted to control engine torsional-vibration behavior during the second engine operating state.
