Abstract:
1. A transmission comprising: an input member; an output member; a first motor/generator having a first rotor; a second motor/generator having a second rotor; a first planetary gearset, a second planetary gearset, and a third planetary gearset each having a respective first planetary member, a respective second planetary member, and a respective third planetary member; said first, second, and third planetary members of the first planetary gearset, said input member, and said first rotor being coaxially disposed on, and selectively rotatable about, a first axis; said first, second, and third planetary members of the second planetary gearset and said first, second, and third planetary members of the third planetary gearset being coaxially disposed on, and selectively rotatable about, a second axis; said second rotor being disposed on, and selectively rotatable about, a third axis; said output member being disposed on, and selectively rotatably about, a fourth axis; a first axis transfer mechanism operatively interconnecting the second planetary gearset and the first planetary gearset and configured to transmit torque therebetween; a second axis transfer mechanism operatively interconnecting the second rotor and the third planetary gearset and configured to transmit torque therebetween; and a third axis transfer mechanism operatively interconnecting the first planetary gearset, the third planetary gearset, and the output member and configured to transmit torque therebetween.
