A vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a first power disconnection device. A second driveline is adapted to transfer torque to the second set of wheels and includes a second power disconnection device. A hypoid gearset is positioned within one of the first driveline and the second driveline in a power path between the first and second power disconnection devices. The hypoid gearset is selectively disconnected from being driven by the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode. At least one of the first and second disconnection devices includes an active dry friction clutch.

All-wheel drive with active dry disconnect system

A drive axle system and a method of control. The drive axle system may include a first drive axle assembly and a second drive axle assembly that may be operatively coupled via a slip clutch.

System and method of controlling a drive axle system

An axle assembly that may have a housing and a carrier housing. The axle assembly may include one or more quiet lubricant reservoirs that may not receive rotating components of the axle assembly. A seal may be provided in a channel that may be disposed between the housing and the carrier housing.

Axle Assembly

A transfer case having a shift mechanism. The shift mechanism may include a shift rail, a range shift assembly, a mode shift assembly, and a sector cam. The sector cam may control movement of the range shift assembly and the mode shift assembly when the sector cam is rotated.

Transfer case having a shift mechanism

A two-speed power take-off unit adapted for installation in an all-wheel drive vehicle having a transversely mounted engine/transaxle powertrain. The two-speed power take-off unit includes a planetary gear reduction unit capable of establishing a high-range and a low-range drive connection between the powertrain and a transfer assembly. The transfer assembly provides drive torque to a front differential assembly driving the front wheels and a PTU gearset driving the rear wheels.

Two-speed power take-off unit

A vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a synchronizing clutch. A second driveline is adapted to transfer torque to the second set of wheels and includes a power disconnection device and a friction clutch. A hypoid gearset is positioned within the second driveline in a power path between the synchronizing clutch and the power disconnection device. The friction clutch and the power disconnection device are positioned on opposite sides of the hypoid gearset. The hypoid gearset is selectively disconnected from being driven by the first driveline, the second driveline or the wheels when the synchronizing clutch and the power disconnection device are operated in disconnected, non-torque transferring, modes.

AWD vehicle with disconnect system

A multi-wheel drive system for a vehicle and a method of control. The system may include first and second inlet valves that may control the flow of fluid to a gerotor pump that may actuate a clutch to provide torque to a wheel set.

Multi-wheel drive system and method of control

A differential assembly having a clutch collar actuator mechanism. The clutch collar actuator mechanism includes an actuator and a fork that may pivot about a pivot axis to actuate a clutch collar.

Two-speed power take-off unit with mode clutch

A vehicle drive train includes a first power disconnection device and a first driveline for transferring torque to a first set of wheels. A second driveline for transferring torque to a second set of wheels includes a differential gearset having an output coupled to a second power disconnection device. A hypoid gearset is positioned within the second driveline in a power path between the first and second power disconnection devices. The second power disconnection device includes a clutch having a first set of clutch plates fixed for rotation with the differential gearset output. The clutch further includes a second set of clutch plates fixed for rotation with a shaft adapted to transfer torque to one of the wheels of the second set of wheels. A valve limits a flow of coolant to the clutch when the second power disconnection device operates in a disconnected mode.

AWD vehicle with active disconnect coupling having controlled lubrication

A torque transfer coupling includes first and second rotary members. A transfer clutch operatively connects the first and second rotary members. A piston, disposed in a piston chamber, is actuable to engage the transfer clutch. A hydraulic pump in fluid communication with a sump containing hydraulic fluid has a first pump member fixed for rotation with the first rotary member and a second pump member fixed for rotation with the second rotary member such that relative rotation between the first and the second pump members generates a fluid pumping action. A first flow path supplies hydraulic fluid from the hydraulic pump to the piston chamber. A second flow path supplies hydraulic fluid from the piston chamber to a control valve for regulating the pressure of the hydraulic fluid supplied to the piston chamber. The second flow path includes an aperture extending through the second pump member.

Hydraulic coupling

A drive axle assembly that may include an input shaft, an intermediate shaft, an output shaft, and an actuator unit. The actuator unit may move the intermediate shaft between a first position in which the intermediate shaft transmits torque to the output shaft and a second position in which the intermediate shaft does not transmit torque to the output shaft.
