In one aspect, a system for reducing torsional vibration of an engine having a crankshaft is provided. The system includes an isolation device including a shaft adapter mounted to the crankshaft, a pulley rotatably mounted to the shaft adapter, and at least one isolation spring resiliently transmitting torque between the pulley and the shaft adapter. The system also includes a torsional vibration damper mountable to the crankshaft. A noise generating space extends axially between the isolation device and the torsional vibration damper. The system also includes a noise cancelling ring extending axially from one of the isolation device and the torsional vibration damper toward the other of the isolation device and the torsional vibration damper and at least partially radially enclosing at least a portion of the noise generating space.
在一方面中,提供了一种用于减少具有曲轴的发动机的扭转振动的系统。该系统包括隔离装置,该隔离装置包括轴适配器、带轮以及至少一个隔离弹簧,该轴适配器安装至曲轴,该带轮以可旋转的方式安装至轴适配器,至少一个隔离弹簧在带轮与轴适配器之间弹性地传递扭矩。该系统还包括能够安装至曲轴的扭转振动阻尼器。噪声产生空间在隔离装置与扭转振动阻尼器之间轴向延伸。该系统还包括噪声消除环,该噪声消除环从隔离装置和扭转振动阻尼器中的一者朝向隔离装置和扭转振动阻尼器中的另一者轴向延伸,并且至少部分地径向封围噪声产生空间的至少一部分。
