Propshaft Assembly With Damper

摘要

A propshaft assembly that includes a tubular member, first and second end connections coupled to opposite ends of the tubular member and a damper that is received in the tubular member and positioned between the first and second end connections. The tubular member has a wall member that defines an interior circumferential surface. The damper has a first damping device, a second damping device and a third damping device. The first damping device has a first core and a first damping member that is fixed to the first core. The first damping member extends helically about the first core and engages the interior circumferential surface. The second damping device is formed of foam and is positioned in the tubular member between the first and third damping devices. The second damping device engages the interior circumferential surface. The third damping device has a second core and a second damping member that is fixed to the second core. The second damping member extends helically about the second core and engages the interior circumferential surface.
