    • A propshaft assembly that includes a tubular member, first and second end connections coupled to opposite ends of the tubular member, and a damper received in the tubular member and positioned between the first and second end connections. The damper includes a core, a first damping member and a second damping member. The core is a hollow structure. The first damping member is fixedly coupled to the core. The first damping member includes a contact element that extends radially from and helically about the core. The contact element is formed of an elastic, rubbery material and is engaged to the interior circumferential surface. The second damping member is formed of closed-cell foam and fixedly coupled to the core. The second damping member extends helically about the core and engages the interior cylindrical surface.
    • 包括管状构件的传动轴组件,联接到管状构件的相对端部的第一和第二端连接器和容纳在管状构件中并定位在第一和第二端部连接件之间的阻尼器。 阻尼器包括一个铁芯,一个第一阻尼件和一个第二阻尼件。 核心是中空结构。 第一阻尼构件固定地联接到芯部。 第一阻尼构件包括从芯部径向延伸并且螺旋地围绕芯部延伸的接触元件。 接触元件由弹性橡胶材料形成并且接合到内周面。 第二阻尼构件由闭孔泡沫形成并且固定地连接到芯。 第二阻尼构件围绕芯部螺旋地延伸并接合内部圆柱形表面。
