摘要： A shift apparatus for shifting a transfer case between a two-wheel drive mode and a four-wheel drive mode. The shift apparatus includes a sector plate supported within the transfer case for rotation about an axis. A first pin member is biased into engagement with a first surface of the sector plate. The first pin member is adapted to move a first shift fork in response to selective rotation of the sector plate between first and second positions corresponding to the two-wheel drive mode and the four-wheel drive mode of the transfer case. The sector plate first surface has a first cam edge provided for positioning the first shift fork in the first position, a second cam edge for moving the first shift fork between the first position and the second position in response to rotation of the sector plate, and a third cam edge for retaining the said first shift fork in the second position upon continued rotation of the sector plate. According to the present invention, the second cam edge includes a plurality of sequentially ramped surfaces which are each adapted to cause a variable range of axial forces to be exerted on the first pin member during movement thereof between the first and second positions.

摘要： A controllable, multi-mode, bi-directional overrunning mode clutch and a shift system adapted for use in a power transfer assembly for transferring drive torque from a primary driveline to a secondary driveline so as to establish a four-wheel drive mode. The mode clutch includes a first ring journalled on a first rotary member, a second ring fixed to a second rotary member, and a plurality of rollers disposed in opposed cam tracks formed between the first and second rings. The first ring is split to define an actuation channel between its end segments. A cam member is moveable between positions engaged with and released from one or both end segments of the split first ring. The shift system includes a mode fork which controls movement of the cam member for establishing a two-wheel drive mode in addition to on-demand and locked four-wheel drive modes.

摘要： A full-time two-speed transfer case is equipped with an integrated planetary gearset assembly and a range shift mechanism to provide high-range and low-range drive connections. The integrated planetary gearset assembly includes a first gearset which acts as a two-speed reduction unit and a second gearset which acts as an interaxle differential. The synchronized range shift mechanism is arranged to concurrently move two components of the first gearset and can be synchronized to permit on-the-move range shifts. The transfer case is also equipped with a dual-mode bi-directional overrunning clutch and a mode shift mechanism to establish automatic full-time and locked four-wheel drive modes.

摘要： A controllable, multi-mode, bi-directional overrunning clutch assembly and a mode shift system are adapted for use in a transfer case for transferring drive torque from a primary output shaft to a secondary output shaft so as to establish four-wheel drive modes. The clutch assembly includes a first ring journalled on a first rotary member, a second ring fixed to a second rotary member, and a plurality of rollers disposed in opposed cam tracks formed between the first and second rings. The first ring is split to define an actuation channel having a pair of spaced end segments. An actuator ring is moveable between positions engaged with and released from the end segments of the first ring. The shift system includes a moveable clutch actuator which controls movement of the actuator ring for establishing an on-demand four-wheel drive mode and a locked or part-time four-wheel drive mode.

The range unit includes a planetary gearset driven by an input shaft, and a synchronized dog clutch assembly for releasably coupling one of the input shaft or an output component of the planetary gearset to an input member of the interaxle differential. The interaxle differential further includes a first output member driving a first output shaft, a second output member operably driving a second output shaft. The clutch assembly is a multi-plate friction clutch operably disposed between the first and second output shafts. The power-operated actuation mechanism includes a range actuator assembly, a ball-ramp clutch actuator assembly and a motor assembly operable to control actuation of the range actuator assembly and the clutch actuator assembly.
