Abstract: A propeller shaft assembly includes a propeller shaft extending along an axis between a first and second shaft end. A propeller shaft yoke is operably connected to one of the first or second shaft ends and includes a body presenting a mounting surface extending circumferentially about the axis. A tuned damper extends radially outwardly from the mounting surface and includes a first damper ring disposed in abutting and encircling relationship with the mounting surface and a second damper ring disposed in abutting and encircling relationship with the first damper ring. The tuned damper includes a retention lip extending radially downwardly from the second damper ring in axially spaced relationship with the mounting hub by an axial spacing distance D for protecting the tuned damper from axial impact forces and improving the robustness of the tuned damper mounted on the mounting surface.

A protective shoulder extends radially outwardly from the mounting surface in spaced and covering relationship with one of the first or second damper sides for protecting the tuned damper from axial forces originating from a respective first or second yoke end of the propeller shaft yoke.

Abstract: A seal for sealing between a trunnion and bearing cup of a joint member includes a main annular body. A plurality of annular lips extend radially inwardly from the main body. The lips are configured for engaging an outer bearing surface of the trunnion. A first one and a second one of the lips slope in a first direction with respect to the outer bearing surface of the trunnion and a third one of the lips slope in a second direction with respect to the outer bearing surface of the trunnion.

Abstract: A driveshaft apparatus includes a main driveshaft, a collar, and a driveshaft yoke, which attaches to a flange yoke via a cardan joint. The flange yoke is configured to attach to a transmission, transfer case or differential, where the torque from the transmission or transfer case is transmitted through the driveshaft to the differential or drive axle. The driveshaft yoke includes a stem portion having a reduced diameter relative to the main driveshaft, which may be in the form of a tube. The reduced diameter of the stem portion shifts the larger diameter further away from the flange yoke, and provides an annular space outside of the stem portion. The annular space provides increased clearance to a tool used to drive the bolts that attach the flange yoke to the transmission, transfer case, drive axle, or the differential. The stem portion may attach to the driveshaft via the collar.
