Linear actuator control system for split axle drive mechanism
 A control system for automatically operating the clutch in a single clutch split axle mechanism responsive to an operational mode of a transfer case in a part-time four-wheel drive vehicle comprises an electro-thermal linear actuator mounted on the split axle mechanism for actuating the clutch and an electric switch mounted on the transfer case for controlling the electro-thermal linear actuator responsive to the operational mode of the transfer case. The electro-thermal linear actuator includes a time delay means so that four-wheel drive can be selected while the vehicle is in motion.
