    • 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.
    • 一种传动系,其包括具有预定数量的气缸的内燃机,并且可在所有汽缸处于运行状态的第一发动机运转状态下工作,以及一些气缸不工作的第二运转状态。 传动系具有至少一个扭转振动阻尼器和至少一个离心力摆的扭转振动阻尼系统。 为了提高传动系的扭转振动特性,离心力摆和任选的扭转振动阻尼器适于在一个操作状态下控制发动机的扭转振动特性,以及可选地扭转振动阻尼器 第二离心力摆适于在另一发动机工作状态下控制发动机的扭转振动特性。
