Abstract
A power transmission apparatus of a hybrid electric vehicle may include a first input shaft mounted along an axis of an engine shaft and selectively connectable to the engine shaft, a second input shaft formed as a hollow shaft, coaxially mounted with the first input shaft, and fixedly connected to a rotor of the first motor-generator, a third input shaft formed as a hollow shaft, coaxially mounted with the first input shaft, and selectively connectable to the first input shaft, an intermediate shaft mounted in parallel with the first input shaft, an output shaft mounted in parallel to the first input shaft and outputting a shifted torque, a planetary gear set mounted on the output shaft, having an element fixed to the output shaft and forming a shifted torque, and a plurality of gear sets mounted on the first, second, and third input shafts, the intermediate shaft, and the output shaft.
