A shift assembly for a transfer cases, manual and semi-automatic transmissions comprises a drive motor (130) having a worm gear output (126) which engages and drives a gear (122) having an eccentric drive pin (118) disposed parallel to and offset from the axis of a rotation of the gear. The drive pin engages a slot (116) in a shift fork (106) which extends normal to the axis of movement of the shift fork and associated speed change or gear shift mechanism. The shift fork is disposed upon and supported by a shift rail (112). Uni-directional or bi-directional rotation of the drive motor (130) rotates the gear (122) and sequentially moves the eccentric pin (118), shift fork and shift mechanism between first and second terminal positions and, typically, a center or intermediate, neutral position. <IMAGE> |
