    摘要: A hybrid transmission providing multiple modes of operation in a compact arrangement is provided and includes first and second planetary gear sets and first and second electric machines. An electric machine shaft directly couples the first planetary gear set to the second planetary gear set and the second electric machine to the second planetary gear set. The second electric machine is selectively directly coupled to an output shaft via a first clutch mechanism, and indirectly coupled to the output shaft via the second planetary gear set and a drive shaft, which extends parallel to the electric machine shaft and external to the second electric machine. A second clutch mechanism selectively couples the first electric machine to a carrier of the second planetary gear set and a third clutch mechanism selectively couples a ring gear of the second planetary gear set to a hybrid drive unit housing.

    摘要: 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.

    摘要: Multi-mode operation is provided for an electrically variable transmission for a motor vehicle. The multi-mode electrically variable transmission provides for multiple gear ratios and power flow configurations including fixed gear operation. An improved input-split planetary gear set configuration is provided for the multi-mode electrically variable transmission. The multi-mode electrically variable transmission may be operated in its desired efficiency and/or performance range more frequently. Further, the transmission reduces clutch torques and provides improved functionality in range-extended electric vehicles and battery electric vehicles. The multi-mode electrically variable transmission is provided with a fixed gear operating capability for improved highway cruising and incorporates a reverse gear for reverse operation.
