Abstract
A power transmission apparatus for a vehicle is disclosed. The power transmission apparatus includes three concentric input shafts, a transmitting shaft disposed on the peripheral circumference of a first one of the three input shafts without rotation interference, and a central shaft disposed in parallel with the first input shaft. The power transmission apparatus further includes a fixed transmission selectively shifting an input torque depending on the respective gear ratios of three change gear trains disposed between second and third input shafts, the transmitting shaft, and the central shaft. The power transmission apparatus further includes a composite transmission including one planetary gear set having a sun gear fixedly connected to one side of the transmitting shaft.
