ABSTRACT:
A multiple clutch type transmission including a plurality of input shafts, a plurality of clutch devices for releasably and alternately connecting respective ones of said input shafts with an engine output shaft. Each of the input shafts has two driving gears mounted thereon to rotate therewith, a countershaft having freely rotatable driven gears which are in meshing engagement with respective ones of the driving gears on the input shafts, connecting hubs provided on the countershaft for axial sliding movements for selectively connecting the driven gears with the countershaft, clutch actuators for controlling said clutch devices so that selected one of the input shafts is connected through selected one of the clutch devices with the engine output shaft. Hub actuators are provided for actuating the connecting hubs so that selected ones of the driven gears are connected with the countershaft, a control circuit being provided for producing a clutch engaging signal upon receipt of a gear engaging command to thereby engage disengaged one of the clutch devices to establish a substantially synchronized condition between the connecting hub and selected one of the driven gears, then a clutch disengaging signal for disengaging the same clutch device and thereafter a hub actuating signal to operate the hub actuator so that the connecting hub is actuated to thereby connect selected one of the driven gears with the countershaft.
