摘要： A transfer case for a four-wheel drive vehicle having a planetary gear assembly which integrates a gear reduction unit and an interaxle differential into a common assembly. A synchronized range clutch is operably associated with the input to the planetary gear assembly and can be selectively shifted on-the-fly for establishing high-range and low-range speed ratios. A synchronized mode clutch is operably associated with the output of the planetary gear assembly and can be selectively shifted on-the-fly for establishing two-wheel, full-time four-wheel and locked four-wheel drive modes.

摘要： A transfer case is provided with a range unit, an interaxle differential, a clutch assembly and a power-operated actuation mechanism. 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.

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.

摘要： A transfer case for a four-wheel drive vehicle having a planetary gear assembly and a synchronized range clutch which can be selectively shifted on-the-move establishing high-range and low-range drive modes. The planetary gear assembly includes a ring gear, a sun gear, a carrier coupled for rotation with an output shaft of the transfer case, and a pinion gear rotatably supported from the carrier and which is meshed with the ring gear and the sun gear. The range clutch includes a first sleeve coupled for rotation with the ring gear and which is rotatably supported from a second sleeve coupled for rotation with an input shaft of the transfer case. With the range clutch in a first position, the first sleeve is uncoupled from the housing and the second sleeve is coupled to the carrier for driving the output shaft at a first speed ratio relative to the input shaft. With the range clutch in a second position, the first sleeve is coupled to the housing and the second sleeve is coupled to the sun gear for driving the output shaft at a second speed ratio relative to the input shaft.

摘要： A dual planetary differential for a two wheel/four wheel drive vehicle transfer case mechanism providing an unequal torque split between the front and rear wheels during its full-time four wheel drive operation. The dual planetary gear set may be shifted by means of a mode clutch to provide either four wheel drive with full-time differentiation between the front and rear wheels or a part-time four wheel drive mode wherein the dual planetary is in a locked-up condition. The first and second sun gears of the dual planetary have unequal diameters with differing numbers of teeth such that, for example, proportionally more torque is transferred to the rear wheels than the front wheels. The sun gears have complementary frusto-conical web portions arranged in a juxtaposed compact manner within the transfer case.

摘要： A transfer case includes an input shaft, first and second output shafts, and a planetary gearset including a sun gear, a ring gear and planet gears rotatably supported on a carrier coupled to the first output shaft. A collar is driven by the sun gear and selectively drives the carrier. The ring gear is moveable between first and second positions. The collar is coupled to the ring gear for movement therewith between first and second positions. The collar is operable in its first position to couple the sun gear to the carrier and operable in its second position to be released from engagement with the carrier. The ring gear is operable in its first position to be released from coupled engagement with a stationary member and operable in its second position to be coupled to the stationary member. A mechanism moves the ring gear between its first and second positions.
