A power transmission apparatus for a hybrid vehicle is disclosed. The power transmission apparatus for a hybrid vehicle according to an embodiment of the present invention, for realizing multiple fixated shifting stages by applying one planetary gear set in a dual clutch type transmission (DCT), and realizing an electric vehicle mode and a parallel hybrid mode together with the multiple fixated shifting stages by additionally applying one motor/generator to the DCT, comprises: a motor/generator; first and second input shafts; first and second intermediate shafts; an output shaft arranged in parallel with the first and second input shafts to be spaced at regular intervals therefrom, and outputting the torque shifted and transmitted by the first and second input shafts; a planetary gear set arranged on the output shaft to be fixatedly connected to the output shaft through a sun gear, and integrating and shifting the torque selectively received from the first and second input shafts and the first and second intermediate shafts so as to output the shifted torque to the output shaft; a first gear set including a first input gear, a first external gear and a second external gear; a second gear set including a second input gear, a third external gear and a fourth external gear; and a third gear set including a fifth external gear and a sixth external gear.

    하이브리드 차량용 동력전달장치가 개시된다. 본 발명의 일 실시 예에 따른 하이브리드 차량용 동력전달장치는 듀얼 클러치 타입의 변속기(DCT)에 1개의 유성기어세트를 적용하여 다단의 고정 변속단을 구현하고, 1개의 모터/제너레이터를 추가 적용하여 다단의 고정 변속단과 함께 전기 자동차 모드 및 패러럴 하이브리드 모드의 구현이 가능하도록, 모터/제너레이터, 제1, 제2 입력축, 제1, 제2 중간축, 상기 제1, 제2 입력축과 일정 간격을 두고 평행하게 배치되며, 상기 제1, 제2 입력축으로부터 변속되어 전달되는 회전동력을 출력하는 출력축, 상기 출력축 상에 배치되어 선기어를 통하여 상기 출력축 상에 고정 연결되며, 상기 제1, 제2 입력축 및 제1, 제2 중간축으로부터 선택적으로 입력되는 회전동력을 합성 변속하여 상기 출력축으로 출력하는 유성기어세트, 및 제1 입력기어와, 제1 외접기어와, 제2 외접기어를 포함하는 제1 기어열과, 제2 입력기어와, 제3 외접기어와, 제4 외접기어를 포함하는 제2 기어열, 및 제5 외접기어와, 제6 외접기어를 포함하는 제3 기어열을 포함한다.
