Abstract: A clutch actuation device selectively engages a clutch. The clutch actuation device includes two plates, at least one of which being able to rotate relative to the other. Between the two plates is a rounded member, such as a ball, housed within opposing grooves in the respective plates. As the plates rotate relative to one another, the rounded member forces the plates to separate axially from one another. This can engage the clutch. A third plate is placed at a location axially spaced from the second plate. The third plate limits movement of the second plate when moving to the extended position, assuring the second plate does not over-translate axially. A resilient member may be provided between the third plate and a housing. The resilient member can be tuned to properly inhibit the axial movement of the second and third plates according to the packaging constraints.

Abstract: A differential assembly arrangement with optimized pinion shaft bearing lubrication is provided. The assembly includes a housing, a ring gear, a pinion gear, a pinion shaft supported by two rolling element bearings, a sleeve, and a lubrication deflector. The two rolling element bearings, a pinion head bearing bearing and a pinion tail bearing, are located at each end of the sleeve which fits over the pinion shaft. The sleeve helps facilitate the application of a pre-load to the bearings. The lubrication deflector is located along the length of the sleeve for providing the correct amount of lubricant to the two bearings. The deflector is in the form of a ring located on the sleeve or integrated within the sleeve.

Abstract: An actuating piston, and a piston assembly and a disconnect system including the actuating piston are provided. The actuating piston includes an annular backing plate having an axial projection on a first side between an inner radius and an outer radius and an annular piston having a recess between an inner radius and an outer radius. The annular piston is disposed on the annular backing plate so that the axial projection is received in the recess. The actuating piston is selected from a set of actuating pistons, each having a different height based on at least one of the wall thickness of the annular piston being varied or a height of the axial projection being varied, and one of the actuating pistons with a desired height is selected based on an actual height of the friction device.
