摘要： Various embodiments of electrically-variable transmissions are provided that have a first and a second motor-generator, a first and a second planetary gear set, and two torque-transmitting mechanisms, including a rotating-type clutch and a stationary-type clutch. An input member is connected for common rotation with a ring gear of the first planetary gear set. Carriers of both of the planetary gear sets are connected for common rotation with one another, and with an output member. The first motor/generator is connected for common rotation with the sun gear of the first planetary gear set. The second motor/generator is connected for common rotation with the sun gear of the second planetary gear set. The rotating-type torque-transmitting mechanism is a dog clutch with a synchronizer. The stationary-type torque-transmitting mechanism may be either a dog clutch with a synchronizer or a selectable one-way braking clutch (SOWBC).

摘要： A vehicle driveline includes a multi-speed transmission that has four planetary gear sets having continuous interconnections and five torque-transmitting mechanisms selectively engagable to establish eight forward and at least one reverse speed ratio between the transmission input member and the transmission output member. The transmission input and output members define an axis of rotation parallel to an axis of rotation of an engine output member that drives the transmission. At least one rotatable element transfers torque from the engine output member to the transmission input member. The torque-transmitting mechanisms are packaged in different ones of six possible zones within the transmission casing. An additional, final drive planetary gear set and a differential mechanism are also included in the driveline.
