Abstract: A power transfer device can include a housing, first and second input members, first and second output members, a differential, and a pump. The housing can define a sump. The first input member can receive rotational power and rotate about an axis. The second input member can be meshingly engaged with the first input member and can rotate through the sump. The differential case can be drivingly coupled to the second input member. The differential gearset can transmit rotary power between the differential case and the first and second output members. The pump can be disposed about the first input member and can have an inlet, outlet, and pump element. The inlet can be coupled for fluid communication with the sump. The pump element can be drivingly coupled to the first input member and can pump the fluid from the sump when the first input member rotates about the axis.

Abstract: A suspension module with a suspension component, wheel hubs coupled to the suspension component, and a drive system. The drive system has a pair of units that selectively provide drive torque to an associated one of the wheel hubs. Each unit includes a motor, a first reduction gearset and an overrunning clutch. The first reduction gearset is disposed between the motor and its wheel hub and multiplies torque output from the motor. The clutch disconnects the motor from the associated wheel hub so that an output shaft of the motor is not drivingly coupled to the associated wheel hub when a rotational speed of the first portion does not exceed a rotational speed of the second portion. The clutch can be selectively operated to drivingly couple the motor to its wheel hub to permit the motor to be back-driven. A method for operating a hybrid power train is also provided.

Abstract: A drive train module with an electric motor, a clutch differential, a pair of wheel hubs and a pair of shafts, which rotatably couple the wheel hubs to the clutch differential. The clutch differential can have an input member, which can be coupled to an output shaft of the motor, and first and second overrunning clutches. The overrunning clutches permit the electric motor to drive the wheel hubs when the drive train module is activated to provide supplemental drive power, and to prevent the electric motor from being back-driven by the wheel hubs when supplemental drive power is not desired.

Abstract: A suspension module that includes a suspension component, a pair of wheel hubs coupled to the suspension component, and an auxiliary drive system. The auxiliary drive system has a pair of drive units, each of which being configured to selectively provide drive torque to an associated one of the wheel hubs. Each drive unit includes an electric motor, a first reduction gear set and a clutch. The first reduction gear set is disposed between the motor and its wheel hub and multiplies torque output from the motor. The clutch is configured to selectively disconnect the motor from the associated wheel hub so that an output shaft of the motor is not drivingly coupled to the associated wheel hub when a rotational speed of the first portion does not exceed a rotational speed of the second portion. A method for operating a hybrid power train is also provided.

Abstract: A module with an axle assembly, which has a housing, a differential, an input shaft, a pair of shafts and a pair of wheel hubs, and an auxiliary drive unit that includes an electric motor and an overrunning clutch. The differential and the input shaft are disposed in the housing for rotation therein. The differential includes a case and a ring gear that is coupled to the case. The input shaft has a pinion that is meshingly engaged to the ring gear. Each shaft couples the differential to one of the wheel hubs. The overrunning clutch includes an input portion, which is coupled to the output shaft of the electric motor, and an output portion, which is coupled to the input shaft. The output portion is de-coupled from the input portion when a rotational speed of the input portion is not greater than a rotational speed of the output portion.

Abstract: A differential assembly includes a case, a pair of pinion gears, a pair of side gears and an electrically operable coupling including an electromagnet. The coupling selectively drivingly interconnects one of the side gears and the case. The electromagnet of the coupling is axially moveable within the case to selectively place the differential assembly in an open or a locked condition.

Abstract: A method of transitioning between modes of differentiation in a differential includes measuring a vehicle parameter, determining a mode of differentiation, selectively providing an electrical signal to an electromagnet based on the determination, generating a magnetic field, moving the electromagnet and selectively operating the differential in one of an open mode of differentiation and a locked mode of differentiation in response to movement of the electromagnet.
