Electro-mechanical on demand (EMOD) transfer case--dual drive gear and shift fork consolidation

Abstract:

A dual drive gear of an actuation assembly for a transfer case includes an annular disk, a dual drive gear hub, and a sense plate. The annular disk has an inner periphery and an outer periphery. The outer periphery defines a plurality of teeth projecting radially outward. The dual drive gear hub is attached to the inner periphery of the annular disk and has an inner surface that defines a bore extending through a center of the dual drive gear. The dual drive gear hub includes a pair of curved walls projecting from a first axial end face of the annular disk. The sense plate projects from a second axial end face of the annular disk opposite of the first axial end face and includes a plurality of curved wall sections. The annular disk, the dual drive gear hub, and the sense plate are formed together as a single piece.
