    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.

    摘要: A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes. The torque transmitting devices are selectively engageable in combinations of at least three to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.

    摘要: The transmission has a plurality of members that can be utilized in powertrains to provide eight forward speed ratios and one reverse speed ratio. The transmission includes 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.
