    • A torsional vibration damper assembly having stable torsional vibration damping characteristics is provided. The damper assembly comprises an input element, an output element, a damper hub operatively connected to the output element and having a plurality of circumferentially spaced, radial hub arms, a drive plate operatively connected to the input element and having a plurality of circumferentially spaced windows, a plurality of compression springs extending between circumferentially opposed edges of the windows and the hub arms, and a ring member rotatable relative to the input and output elements and surrounding the compression springs for restricting radially outward bending of the compression springs. Since the ring member is not urged against its surrounding constituent parts of the damper assembly when it is subjected to a centrifugal force of itself and a centrifugal force of the compression springs, the damper assembly can provide stable torsional vibration damping characteristics.
    • 提供了具有稳定的扭转振动阻尼特性的扭转振动阻尼器组件。 阻尼器组件包括输入元件,输出元件,可操作地连接到输出元件并具有多个周向间隔开的径向轮毂臂的阻尼器毂,可操作地连接到输入元件的驱动板,并且具有多个周向间隔开的窗 ,多个压缩弹簧,其在所述窗户的周向相对边缘和所述轮毂臂之间延伸;以及环构件,其相对于所述输入和输出元件可旋转并围绕所述压缩弹簧以限制所述压缩弹簧的径向向外弯曲。 由于环形构件经受其自身的离心力和压缩弹簧的离心力时,环形构件没有被推靠在阻尼器组件的周围构成部件上,所以阻尼器组件能够提供稳定的扭转振动阻尼特性。
