Electronic shift on the fly part-time electro mechanical transfer case
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.
