Abstract:
A center bearing assembly for a multi-piece propeller shaft includes a stud yoke extending along an axis A between first and second stud yoke ends to define a central stub shaft rotatable about the axis A. A rotatable weld collar is operably connected to the second stud yoke end of the central stub shaft for simultaneous rotation therewith. The rotatable weld collar includes a body extending from a first collar end disposed adjacent the central stub shaft to a second collar end to define an exterior surface. A tuned damper extends radially outwardly from the exterior surface of the rotatable weld collar for reducing noise, vibration, and/or harshness (NVH) generated during operation of the multi-piece propeller shaft. A first shaft segment is operably connected to the rotatable weld collar and a second shaft segment is operably connected to the stud yoke for transferring a rotational force therebetween.
