In an aspect a device for a driven shaft is provided that receives an input torque that varies cyclically between a peak input torque and a low input torque at a peak input torque frequency, which includes a shaft adapter, a rotary drive member, at least one isolation member, a torsional vibration damping structure including an inertia member and a elastomeric damping member, and a supplemental damping structure. The supplemental damping structure applies a supplemental damping torque to resist relative movement between the rotary drive member and the inertia member in addition to damping provided by the elastomeric damping member. A sum of torques including the supplemental damping torque limits a maximum twist between a first end of the driven shaft and a second end of the driven shaft, to below a yield point of the driven shaft.
在一方面中,提供了一种用于从动轴的装置,该从动轴接收在峰值输入扭矩频率下在峰值输入扭矩与低输入扭矩之间周期性地变化的输入扭矩,该装置包括轴适配器、旋转驱动构件、至少一个隔离构件、包括惯性构件和弹性体阻尼构件的扭转振动阻尼结构件、以及辅助阻尼结构件。除了由弹性体阻尼构件提供的阻尼之外,辅助阻尼结构件还施加了辅助阻尼扭矩以抵抗旋转驱动构件与惯性构件之间的相对运动。包括辅助阻尼扭矩的扭矩之和将从动轴的第一端部与从动轴的第二端部之间的最大扭曲限制在从动轴的屈服点以下。
