    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.

    摘要: A planetary gear train includes input and output shafts, first to fourth planetary gear sets respectively having first to third, fourth to sixth, seventh to ninth, and tenth to twelfth elements. The planetary gear train includes a first shaft connected with the third, fifth, and eighth elements and selectively connected with the input shaft, a second shaft connected with the fourth element and selectively connected with the input shaft, a third shaft connected with the ninth and twelfth elements and fixedly connected with the output shaft, and a fourth shaft connected with the first, sixth, and seventh elements, a fifth shaft fixedly connected with the eleventh element. The planetary gear train includes a plurality of additional shafts selectively connected to the transmission housing and connected to an element of the first and fourth planetary gear sets that is not connected with any of the first to seventh shafts.
