Abstract

An electro-mechanical shift actuator system is provided for a transmission (10) having dual input shafts (14, 16) and with a plurality of drive gears rotatably mounted to each input shaft and having synchronizer mechanisms for engaging each drive gear to one of the input shafts. The shift actuators (128, 219) include an electric motor (234) and a reduction gear assembly (236) for driving a barrel shaped shifter cam (230, 262) having a pair of cam grooves (228, 260) therein. The cam grooves are engaged by shifts lugs (224) mounted to a shift rail (220, 222, 256, 258). The shift rails include shift forks (252, 254, 263, 264) for actuating synchronizers (38, 40, 48, 50) mounted on the input shafts for engaging selected drive gears.
