Abstract: A transfer case of a motor vehicle drivetrain includes a planetary gear set including a ring gear to receive input torque, and a pinion assembly having pinion gears in mesh with the ring gear and a carrier to carry the pinion gears and transmit output torque. A sun gear is in mesh with the pinion gears, is selectively connectable to the carrier and rotatable therewith in a two-wheel drive mode and in a four-wheel-drive high range mode, and is selectively fixable against rotational motion in a four-wheel drive low range mode.

Abstract: A transfer case for a normally rear wheel drive vehicle with selective four wheel drive capabilities is provided. The transfer case has an intermediate gear driven lubrication pump, wherein the machining required for the lubrication pump is almost exclusively conducted from an interior side of the rear shell. The transfer case of the present invention also eliminates the requirement for a cover plate for the pump and an external lubrication tube. The transfer case of the current invention has an internal lubrication pump outlet which has a portion extending in a reinforcing mound of the rear shell thereby providing greater stiffness to a portion of the rear shell supporting the main input shaft rear bearings.

Abstract: An actuation system of a transfer case includes a face cam, a motor, a gear reduction assembly, and an intermediate rotating member. The face cam includes a first member and a second member, and rotation of the first member relative to the second annular causes the first member or the second annular member to displace axially relative to the other member for selective operation of a torque transfer mechanism of the torque transfer device. The gear reduction assembly includes a first planetary gear set that increases torque from the motor by a first ratio, and a second planetary gear set that increases torque from the first planetary gear set by a second ratio and is coaxial with the first planetary gear set and the motor. The intermediate rotating member is rotated by the gear reduction assembly and rotates the first annular member for selective operation of the torque transfer mechanism.

Abstract: A number of variations may include a transfer case comprising an input shaft and a first output shaft sharing a primary axis of rotation; a second output shaft offset from the first output shaft; a range shifter comprising a first cam constructed and arranged to selectively shift a vehicle to a high-range drive mode, a low range drive mode, or a neutral drive mode; a mode shifter comprising a second cam constructed and arranged to actuate a synchronizer which selectively shifts the vehicle between a two-wheel drive mode and a four-wheel drive mode a gear train having a first axis offset from the primary axis, and a reversible electric motor which drives the gear train wherein direction of the rotation of the electric motor determines engagement or disengagement of the mode shifter to selectively shift the vehicle between the two-wheel drive mode and the four-wheel drive mode.
