Abstract:
1. A hybrid powertrain having a transmission selectively driven by an engine, the hybrid powertrain comprising: an input member; an output member; first, second, and third planetary gear sets each having first, second and third members; a first interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set; a second interconnecting member directly continuously interconnecting the second member of the first planetary gear set and the output member with the third member of the third planetary gear set; a third interconnecting member continuously interconnecting the third member of the second planetary gear set with the second member of the third planetary gear set; six torque transmitting mechanisms each selectively engageable to interconnect at least one of the first, second, and third members with at least another of the first, second, third members and a stationary member; an electric motor selectively interconnected with the first member of the second planetary gear set; a first clutch for selectively interconnecting the engine with the input member; a second clutch for selectively interconnecting the electric motor with the input member; a hydraulic pump continuously interconnected with the electric motor; a one-way clutch interconnected between the electric motor and the engine for allowing torque to transfer from the engine to the electric motor and preventing torque from transferring from the electric motor to the engine, and wherein the torque transmitting mechanisms are selectively engageable to establish a plurality of forward speed ratios and at least one reverse speed ratio between the input member and the output member.
