摘要: A power transmission apparatus for a vehicle having an engine and a motor/generator includes first to third input shafts each selectively connected with a motor shaft. A power mediating shaft is coaxially disposed with the first input shaft, and first and second intermediate shafts each are disposed in parallel with the first input shaft. The second intermediate shaft is selectively connected with a transmission housing, and an idle shaft is disposed in parallel with the first input shaft. A first shifting section includes six gear sets disposed on the above shafts and outputs a plurality of intermediate shift-stages shifted from torques received through the first and third input shafts. A second shifting section forms an output torque by combination of torques from the first shifting section and the second input shaft, and an output shaft outputs a torque received from the first and second shifting sections.
