Power transmission apparatus for vehicle

Abstract

A power transmission apparatus for a vehicle may include a first input shaft, a second input shaft, a third input shaft, an intermediate shaft disposed parallel to the first, second, and third input shafts, a transfer gear fixedly disposed on the intermediate shaft and outputting torque thereof, an first shifting member changing torque of an engine into first and second preliminarily shifted torques, and outputting the first and second preliminarily shifted torques, an second shifting member changing the torque of the engine into third and fourth preliminarily shifted torques, and outputting the third and fourth preliminarily shifted torques, and a third shifting member changing the torque of the engine transmitted from the first input shaft and the first preliminarily shifted torque to the fourth preliminarily shifted torque selectively transmitted from the first shifting member or the second shifting member into eight forward speed stages and one reverse speed stage.
