Abstract: A disconnect mechanism for a secondary driveline and method of assembly can be used in an all-wheel drive (AWD) vehicle having a rear driveline module (RDM) for changing drive modes between a two-wheel drive mode and an AWD mode. The disconnect mechanism can include a hydraulically actuated coupling clutch connected to a power take-off unit (PTU) for transferring rotary power from the PTU to the RDM during the AWD mode, a hydraulically actuated first and second rear clutch for rotationally connecting and disconnecting corresponding first and second rear axles drivingly coupled to rear wheels during the AWD mode and two-wheel drive mode, respectively, and a hydraulic actuating assembly including a source of pressurized fluid for actuating the coupling clutch, the first rear clutch, and the second rear clutch, and for synchronizing any speed differential therebetween.

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

Abstract: A self-adjusting clutch (10) can include an automatic adjustment mechanism (20) for decreasing an axial dimension within a clutch pack (14). The adjustment can compensate for wear of the facing surfaces of interposed members located within the clutch pack (14), resulting from repeated engaging and disengaging under a clutch apply load within the clutch (10). The adjustment mechanism (20) can include a reaction plate (12) normally biased toward the clutch pack (14) by a plurality of first springs (22). The adjustment mechanism (20) can further include a plurality of pawls (24) supported for rotation by the reaction plate (12) and biased by a plurality of second springs (26) toward a locking position with respect to a ring member (36). The plurality of pawls (24) can lock the reaction plate (12) against axial movement in a direction of the clutch apply load during clutch actuation.

Abstract: A transfer case for a motor vehicle. An input is rotatable about an axis to receive torque, an output is rotatable about the axis to transmit torque, and a planetary gear set is rotatable about the axis and operatively coupled between the input and the output. A shift sleeve circumscribes and is axially slidably carried along the axis, and a shift sleeve lock is automatically engageable with the shift sleeve responsive to the transfer case exceeding a predetermined rotational speed, to prevent axial movement of the shift sleeve above that speed. A related method is also provided.
