Disclosed is a power transmission apparatus for a hybrid electric vehicle. According to an embodiment of the present invention, provided is a power transmission apparatus for a hybrid electric vehicle, which includes: an input shaft directly receiving rotational power of an engine which is a main power source; an output shaft disposed in parallel with the input shaft at a predetermined interval, and provided with first and second motors/generators which are auxiliary power sources and a planetary gear set which is a power dividing means; and a dependent decelerating device for decelerating the rotational power transmitted from an output gear of the output shaft and differentially distributing the rotational power to a drive shaft, wherein the rotational power of the input shaft is transmitted through two paths of which one allows the rotational power of the input shaft to be selectively transmitted to the output shaft and the other allows the rotational power of the input shaft to be branched from the planetary gear set to be transmitted to the first motor/generator and the output shaft. The output shaft is directly connected to the second motor/generator.

    하이브리드 차량용 동력전달장치가 개시된다. 본 발명의 실시 예에 따른 하이브리드 차량용 동력전달장치는 주동력원인 엔진의 회전동력을 직접 전달받는 입력축; 상기 입력축과 일정간격을 두고 평행하게 배치되어 보조 동력원인 제1, 제2 모터/제너레이터와 동력분기수단인 유성기어세트가 배치되는 출력축; 및 상기 출력축의 출력기어로부터 전달되는 회전동력을 감속시켜 구동축으로 차동 분배하는 종감속 기구를 포함하며, 상기 입력축의 회전동력이 2개의 경로를 통해 전달되도록 하되, 하나의 경로는 상기 입력축의 회전동력이 선택적으로 출력축으로 전달되도록 하고, 다른 하나의 경로는 상기 입력축의 회전동력이 유성기어세트에서 분기되어 상기 제1 모터/제너레이터와 상기 출력축으로 전달되도록 하고, 상기 출력축은 상기 제2 모터/제너레이터와 직접 연결된다.
