An axle disconnect and differential locking system for single or multiple axle vehicles which allows the vehicle to selectively engage and disengage an axle half shaft from the differential side gear. Additionally, the system allows the vehicle to selectively switch between locked and unlocked differential driving modes. The system has a first position, a second position and a third position. At the first position, the system is not meshingly engaged with the differential side gear or the differential case. At the second position, the system is meshingly engaged with the differential side gear but is not meshingly engaged with the differential case. At the third position, the system is engaged with the differential side gear and the differential case. In one embodiment the system is a sliding collar. According to another embodiment, the system includes an axle disconnect collar, a differential locking collar and a biasing member disposed therebetween.

A dual clutch transmission comprises a housing formed therein with a gear chamber incorporating an odd-numbered speed gear train group and an even-numbered speed gear train group. An end of the input shaft is connected to an engine, and a cover is detachably attached to the housing opposite the end of the input shaft so as to define a clutch chamber divided from the gear chamber. A first clutch for the odd-numbered speed gear train group and a second clutch for the even-numbered speed gear train group are disposed in the clutch chamber. Fluid passages for supplying hydraulic fluid to the first and second clutches are formed in the cover.

An all-wheel drive vehicle driveline that includes a housing assembly with a housing structure and a cover. In one form, components of the driveline can be assembled to the housing structure and cover in such a way that an intermediate shaft, which is assembled to the cover, and an input shaft, which can be rotatably mounted to the housing structure, can be slidably engaged to one another. In another form, the cover defines a reservoir that is configured to feed fluid to a pump that is mounted to the cover.

An AWD drivetrain is configured to primarily direct drive torque from a transversely-aligned powertrain assembly through an auxiliary power transfer unit to a rear driveline and selectively transmit drive torque to a front driveline via actuation of at least one power-operated clutch. The auxiliary power transfer unit includes an input component drivingly connected to the powertrain assembly, and an output component connected to the input component by a hypoid gearset The output component is operatively connected to the rear driveline and is configured to normally transfer the drive torque to the rear driveline.

A transaxle comprises first and second input shafts coaxial to each other, an output shaft drivingly connected to the second input shaft, a torque limiter interposed between the first and second input shafts, and a housing incorporating the first and second input shafts, the output shaft and the torque limiter. The torque limiter includes first and second sleeves. The first sleeve is fitted to the first input shaft unrotatably relative to the first input shaft. The second sleeve is fitted to the second input shaft unrotatably relative to the second input shaft. The first and second sleeves are layered in a radial direction of the first and second input shafts so as to be pressed against each other with a radial surface pressure to limit a torque transmitted between the first and second sleeves to a limiting value.

A vehicle comprises a transaxle, a battery and a load carrying bed. The transaxle includes a casing incorporating a drive train and supporting an axle and includes an electric motor mounted on the casing to drive the axle via the drive train. The battery is provided for supplying electric power to the electric motor. The transaxle and the battery are disposed below the load carrying bed so as to overlap the load carrying bed when viewed in plan.

A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.

A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.
