摘要： A semi-automatic transmission comprises an input shaft; a countershaft; constantly meshed gears arranged between the input shaft and the countershaft; and an electrically controlled dog clutch operatively disposed on one the input shaft and the countershaft. The dog clutch is of a type which is free of a synchronizing mechanism and fastens one of the meshed gears to a corresponding one of the input shaft and the countershaft when operated, thereby to establish a given torque transmission path from the input shaft to the countershaft. An electromagnetic multiple disc clutch is employed, which has an input part adapted to be driven by an engine and an output part connected to the input shaft. A control unit is further employed, which controls the dog clutch in accordance with information signals applied thereto.
