Abstract
An electrically variable transmission includes an input member, first and second motor-generators and a gear reduction arrangement including at least a first gear coupled to at least one second gear. A first planetary gear set can include a first sun gear, a first ring gear and a first carrier rotatably supporting a plurality of pinion gears in meshing engagement with the first sun gear and ring gear. The first carrier can be non-rotatably coupled to the input member and the first ring gear can be non-rotatably coupled to the at least one second gear. The sun gear can be non-rotatably coupled to the first motor-generator and the first gear can be non-rotatably coupled to the second motor-generator. The torque transmitting device can be configured to selectively fix rotation of the input member in at least one of a first rotational direction and a second opposite rotational direction.
