Abstract
A rotational coupling device having a self-contained wet clutch pack and fluid isolated field shell is provided. The device includes a hub disposed about a rotational axis. A rotor is supported on, and configured for rotation about, the hub and defines a radially extending wall and a chamber on one side of the wall surrounding said hub and defining a sump containing a fluid. An armature is supported on the hub for rotation therewith within the chamber and axially spaced from the wall. A field shell is disposed on an opposite side of the rotor wall from the armature and houses a conductor. The field shell is isolated from the fluid in the chamber. Energization of the conductor urges the armature in a first axial direction towards the radially extending wall of said rotor to couple the rotor to the hub for rotation therewith.
