摘要:
The hybrid transmission has a plurality of members that can be utilized in powertrains to provide eight forward speed ratios and one reverse speed ratio. The hybrid transmission includes a motor/generator, three planetary gear sets, five torque-transmitting devices, one fixed interconnection, three external gear sets and a final drive gear set. The powertrain includes an engine and torque converter that is continuously connected to one of the planetary gear members and an output member that is continuously connected with one of the external gear sets. The five torque-transmitting devices provide interconnections between various planetary and external gear members, the input shaft, and the transmission housing, and are operated in combinations of three to establish eight forward speed ratios and one reverse speed ratio.
