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.

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: A ball-ramp clutch includes two stamped ramp plates and at least one molded support ring. The molded support ring transmits axial force from one of the ramp plates to a thrust bearing, which, in turn, transmits the axial force to the pressure plate of a clutch pack. The molded support ring may radially locate one of the races of the thrust bearing. The molded support ring may be plastic.

Abstract: A linear contactless displacement sensor assembly is provided. The sensor assembly can include a shaft configured to translate linearly, and a sleeve rotatably coupled about the shaft and linearly fixed such that the shaft can linearly translate through the sleeve as the sleeve rotates. The sleeve includes an outer surface having a threading that varies in pitch. A tooth is disposed in the threading and fixed on a linear track such that the tooth moves linearly as the sleeve rotates. A sensor is configured to sense a location of the tooth along the linear track. This allows the sensor assembly to measure an amount of linear movement and a corresponding amount of rotation of the sleeve.
