摘要： A powertrain includes a power transmission having an input shaft continuously connected directly between an engine and a planetary gear member of a first planetary gearset. Another member of the planetary gearset is selectively grounded by a torque transmitting mechanism to establish a reaction member during the launch of a vehicle incorporating the powertrain. The reaction member is established during both the lowest forward drive ratio and the reverse drive ratio. A third member of the planetary gearset transmits the torque from the input shaft, as modified by the planetary gearset, to other planetary gearsets in down stream power flow arrangement with the first planetary gearset.

摘要： A power transmission includes a rotary input member adapted to receive drive torque from a source of torque, a rotary output member and a torque transmitting mechanism selectively operable to transfer drive torque between the input member and the output member. The torque transmitting member includes a selectively operable one-way clutch including a rotatable member for switching the one-way clutch between a released mode and a locked mode. The torque transmitting mechanism also includes a friction clutch and an actuator. The friction clutch is operable to transmit torque to the rotatable member and control the mode of operation of the one-way clutch. The actuator is operable to apply a clutch and brake engagement force to the friction clutch.
