    Abstract: A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.

    Abstract: A power transfer case (10) transfers drive torque from the input member to the output member. The power transfer case (10) includes a lubrication system (18), a hydraulically actuated friction clutch assembly (12), and a hydraulically actuated range shift assembly (14). An on-demand electric lube pump (16) can supply a fluid under pressure. An accumulator (20) is selectively supplied with fluid under pressure from the on-demand lube pump (16). A first valve (22) selectively directs fluid under pressure from the on-demand lube pump (16) to the lubrication system (18) when in a first position (22a) and to the accumulator (20) when in a second position (22b). A second valve (28) selectively directs fluid under pressure from the accumulator (20) to the range shift assembly (14) when in a first position (28a), to the friction clutch assembly when in a second position (28b), and isolates the accumulator (20) from the range shift assembly (14) and the friction clutch assembly (12) when in a third position (28c).

    Abstract: A hydraulic actuation system (10) and method of assembly for disconnecting a secondary driveline (27) can be used in an all-wheel drive (AWD) vehicle (14) having a power take-off unit (PTU) (42) for transferring rotary power to the secondary driveline (27). The hydraulic actuation system (10) can include a source of pressurized fluid (50), a hydraulically actuated synchronizer (44) for synchronizing rotary motion between the PTU (42) and the secondary driveline (27), at least one hydraulically actuated clutch assembly (11a, 11b) for connecting and disconnecting secondary vehicle wheels (29a, 29b) with respect to the secondary driveline (27), an area control solenoid (ACS) valve (54) in fluid communication with the source of pressurized fluid (50) to modulate pressure to engage and disengage the synchronizer (44), and at least one variable force solenoid (VFS) valve (56a, 56b) in fluid communication with the source of pressurized fluid (50) to modulate pressure to the at least one hydraulically actuated clutch assembly (11a, 11b).
