Abstract
A hybrid transmission connected with a prime power source, including an input member for receiving power input from the prime power source, a two degree-of-freedom gear mechanism having a first axis and including at least four rotating members that are associated to rotate about the first axis, a first motor/generator having a second axis aligned with the first axis of the two degree-of-freedom gear mechanism, and a second motor/generator having a third axis offset from and parallel to the first axis. The first motor/generator is drivingly connected with the first rotating member of the two degree-of-freedom gear mechanism. The second motor/generator is drivingly connected with the second rotating member of the two degree-of-freedom gear mechanism.
