Abstract:
A dual transmission includes a first input shaft, a second input shaft, a first input clutch adapted to drivingly couple a power source to the first input shaft and a second input clutch adapted to drivingly couple the power source to the second input shaft. First, third and fifth drive gears are driven by the first input shaft. Second, fourth and sixth drive gears are driven by the second input shaft. First, second, third, fourth, fifth and sixth driven gears selectively drive a countershaft. The first through sixth drive gears are in meshed engagement with the corresponding first through sixth driven gears. First through sixth synchronizer clutches are individually associated with the respective first through sixth drive or driven gears to provide first through sixth gear drive ratios to the countershaft. Each synchronizer clutch is selectively actuated by an associated first through sixth electric actuator.
