Abstract
A power transmission system of a hybrid electric vehicle may include an input device including a first input shaft receiving torque of the engine and a second input shaft disposed without rotational interference with the first input shaft, a planetary gear set including a first rotation element directly connected to the second input shaft, a second rotation element directly connected to the first input shaft, and a third rotation element, a supplemental input device including a first intermediate shaft and a second intermediate shaft, a friction member selectively connecting the first intermediate shaft to a transmission housing, an output device operably connected to the input device and the supplemental input device and outputting torque transmitted from the input device or the supplemental input device, and a final reduction device decelerating torque transmitted from the output device and outputting the decelerated torque.
