An axle assembly having a shift mechanism. The shift mechanism includes an actuator that is configured to move the shift collar along the axis to selectively connect a member of a set of drive pinion gears to a drive pinion. A drive member is also provided that is configured to move the shift collar when actuated.

Axle assembly having a shift mechanism

An axle assembly having a collar that receives a shift collar that is moveable along an axis. An alignment rod may be provided to inhibit rotation of the collar about the axis. A linkage retaining device may be provided that is selectively engageable with a linkage that is operatively connected to the shift collar to inhibit rotation of the linkage.

Axle assembly having a shift collar

An axle assembly having a gear reduction unit that is configured to operatively connect an electric motor to a drive pinion. The gear reduction unit includes at least two gear sets. At least one clutch is engageable to provide a torque path between the electric motor and the drive pinion.

Axle assembly having a gear reduction module with multiple gear sets

An axle assembly having a gear reduction unit that is configured to operatively connect an electric motor to a drive pinion. The gear reduction unit includes at least two gear sets. A shift collar is rotatable with the drive pinion and moveable along the drive pinion to couple a gear set to the drive pinion.

An axle assembly that includes a first gear mechanism, a second gear mechanism, and a differential assembly. The first gear mechanism and the differential assembly may be rotatable about a first axis. The second gear mechanism may be rotatable about a second axis. Torque may be transmitted between the first gear mechanism and the differential via the second gear mechanism.

Axle assembly having gear mechanisms

An axle assembly having a gear reduction unit that is configured to operatively connect an electric motor to a drive pinion. The gear reduction unit includes at least one countershaft gear set. At least one clutch is engageable to provide a torque path between the electric motor and the drive pinion.

An axle assembly having a housing assembly, an electric motor module, and a transmission module. A first lubricant passage may route lubricant from the housing assembly to the transmission housing cavity of the transmission module. The first lubricant passage may extend through a motor housing, a motor cover, and a first transmission housing.

Axle assembly having a transmission module

A power takeoff unit for an automotive vehicle being a normally front-wheel drive vehicle that is convertible to all wheel drive. The takeoff unit includes an input shaft supported in a housing, the input shaft is torsionally connected with a transmission of said vehicle. An output shaft concentric with the input shaft is provided, the output shaft is torsionally connected with the rear wheels of the vehicle. A shift collar to selectively connect said input shaft with said output shaft is provided. A shift fork is provided to translate the shift collar, the shift fork having a main body with a bore. A cylinder is connected with the housing. A piston is slidably mounted within said cylinder. A headed fastener is provided with a shank extending through the shift fork main body bore. The fastener head engages the shift fork, the fastener's shank being threadably engaged with the piston to capture the shift fork with the piston.

Power transfer unit (PTU) assembly with cylinder

An arrangement of a vehicle is provided having normal transverse engine/transmission normal two-wheel drive operation which can be selectively placed into four-wheel drive operation wherein a pump which powers the coupling or uncoupling is independent of the transmission lubrication pump and is powered by the transmission.

A number of variations may comprise a method comprising: a lubrication system for a transfer case comprising: actively managing an oil level in a plurality of sumps in a transfer case by rotating at least one rotating element in the transfer case to transfer oil through the transfer case to lubricate the transfer case.

ECO lubrication method for a transfer case

An arrangement of a vehicle is provided having normal transverse engine/transmission normal two-wheel drive operation which can be selectively placed into four-wheel drive operation wherein a pump which powers the coupling or uncoupling can be positioned downstream of a power takeoff unit without utilization of an electrically powered pump or transmission powered pump.

Front wheel drive based power transfer unit (PTU) with hydraulically actuated disconnect

A differential assembly includes a differential housing including a substantially spherically shaped chamber. A pair of side gears are rotatably positioned in the chamber in driving communication with a pair of pinion gears. A pair of springs are positioned in engagement with the end faces of the side gears to minimize gear lash between the side gears and the pinion gears.
