Patent attributes
A drive module includes a Ravigneaux gearset, first and second input shafts, shift member, and differential. The first planet gears of the gearset can engage the first sun gear and the second planet gears, which can engage the second sun gear. The first input shaft can rotate with the second sun gear and receives torque from a first motor. A first gear can be coupled to the carrier of the Ravigneaux gearset for rotation therewith and meshingly engages the differential input. The second input shaft receives torque from a second motor and is drivingly coupled to the differential input. When the shift member is in a first position, the shift member drivingly couples the first sun gear to a first differential output. When the shift member is in a second position, the shift member couples the first sun gear to a housing to prevent rotation of the first sun gear.
