ABSTRACT:
A viscous damped driveline coupling has two concentric tubes concentric with a torsion bar where the torsion bar is nonrotatably connected to both a drive coupling and a driven coupling. An outer tube has a first end connected to the drive coupling and a second end connected to a driven ring where the driven ring contacts ring forks contacting the driven coupling at travel stops thereby providing for lost motion between the driven coupling and the outer tube. A concentric inner tube is connected to the driven coupling and is viscously coupled to the outer tube. As the torsion bar transfers relatively low levels of torque between the drive and driven couplings, the viscous layer between the outer and inner tubes provides viscous damping. Upon contacting the travel stops, the outer tube then carries any additional torque in the driveline coupling.
