摘要： A torque-transmitting mechanism having a latching apparatus includes a frictional drive connection between two components of a transmission mechanism. The torque-transmitting mechanism is controlled in engagement and disengagement through an apply piston to which an apply component is presented. The latching mechanism will prevent disengagement of the torque-transmitting mechanism even when the apply force is disestablished. The latching mechanism is provided with a controlled release to permit the apply force to be reestablished and thereafter control disengagement of the torque-transmitting mechanism.

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 torque-to-thrust apply mechanism for a torque-transmitting mechanism includes an input electric motor supplying torque to a first rotary to thrust ball and ramp mechanism which converts rotary motion to an apply force between an apply plate and a plurality of friction discs within a torque-transmitting mechanism. The mechanism also includes a second rotary-to-thrust mechanism which receives input rotation from the first apply member as a result of reaction torque. The rotation of the second mechanism results in additional thrust on the friction plates to amplify the apply force of the torque-to-thrust apply mechanism.
