Abstract:
An electric drive unit for a powertrain system including first and second drivelines and a primary propulsion system for translating rotational torque to the first driveline. A motor acts to generate rotational torque and a pinion is disposed in selective communication therewith. A differential is interposed between the pinion and the second driveline of for splitting torque therebetween. A first planetary is disposed between the motor and pinion, and a second planetary is disposed between the first planetary and pinion. A dog clutch interposed between the pinion and the planetaries is movable between a first position wherein torque from the motor is translated through the first planetary and the dog clutch to drive the second driveline at a first drive ratio, and a second position wherein torque from the motor is translated through both planetaries and the dog clutch to drive the second driveline at a second drive ratio.
