Disclosed is a power transmission system for a four-wheel drive hybrid vehicle. The power transmission system for a four-wheel drive hybrid vehicle according to an embodiment of the present invention includes: a first input shaft connected to an output shaft of an engine; a second input shaft arranged at an equal shaft at a rear part of the first input shaft; a first motor/generator which has a motor function and a generator function, and is connected to the second input shaft; a second motor/generator which has a motor function and a generator function, and is constituted in a rear-wheel transmission housing; a planetary gear set which is arranged between the first and the second input shaft, wherein a first rotary element among three rotary elements is directly connected to the second input shaft, and a second rotary element is directly connected to the first input shaft, and a third rotary element is selectively inputted to the first input shaft; a power delivery unit to output rotary power delivered from the first and the second input shaft selectively through two output gears selectively connected to the first and the second input shaft respectively; a power control unit configured at a selectively connected portion; a front-wheel deceleration gear unit which decelerates the rotary power delivered from the power delivery unit and delivers the decelerated rotary power to a front-wheel differential; and a rear-wheel deceleration gear unit which decelerates the rotary power delivered from the second motor/generator and then delivers the decelerated rotary power to a rear-wheel differential.

    4륜 구동 하이브리드 차량용 동력전달장치가 개시된다. 본 발명의 일 실시 예에 따른 4륜 구동 하이브리드 차량용 동력전달장치는 엔진의 출력축과 연결되는 제1 입력축; 상기 제1 입력축의 후방에 동일 축선상으로 배치되는 제2 입력축; 모터와 제너레이터 기능을 가지며, 상기 제2 입력축에 연결되는 제1 모터/제너레이터; 모터와 제너레이터 기능을 가지며, 후륜측 변속기 하우징에 구성되는 제2 모터/제너레이터; 상기 제1, 제2 입력축 사이에 배치되며, 3개의 회전요소 중, 제1 회전요소가 상기 제2 입력축에 직접 연결되고, 제2 회전요소가 상기 제1 입력축에 직접 연결되며, 제3 회전요소가 상기 제1 입력축에 선택적으로 연결되는 유성기어세트; 상기 제1, 제2 입력축에 각각 선택적으로 연결되는 2개의 출력기어를 통하여 상기 제1, 제2 입력축으로부터 전달되는 회전동력을 선택적으로 출력하는 동력전달수단; 상기 선택적으로 연결되는 부분에 구성되는 동력단속수단; 상기 동력전달수단으로부터 전달되는 회전동력을 전륜 디프렌셜에 감속하여 전달하는 전륜 감속기어수단; 및 상기 제2 모터/제너레이터로부터 전달되는 회전동력을 후륜 디프렌셜에 감속하여 전달하는 후륜 감속기어수단을 포함한다.
