Disclosed is a power train of a hybrid automobile. The power train of a hybrid automobile according to an embodiment of the present invention comprises an engine which is a main power source, a set of planetary gears, first and second motors/generators which are auxiliary power sources and arranged on the same axial line, and a final reduction gear which has a differential and to which rotational power of the engine and the rotational power of the second motor/generator are transferred via independent paths. The set of planetary gears has a sun gear which is directly connected to the first motor/generator via a first motor axis, at the same time being selectively connected to a transmission housing. A planetary gear carrier is directly connected to an input axis of engine, at the same time being positioned between a one-way clutch and a torque limiter to be connected to the transmission housing. A ring gear as an output factor is directly connected to a first output gear, and connected to the final reduction gear via a first middle axis. The second motor/generator is directly connected to a second output gear via a second motor axis, to be connected to the final reduction gear via a second middle axis. An embodiment of the present invention is to provide a power train of a hybrid automobile, capable of preventing a one-way clutch from being damaged due to a torque vibration characteristic of an engine, reducing a drag by supporting the inside of planetary carrier and ring gear, and of reducing the size of a set of planetary gears.

    하이브리드 자동차의 동력전달장치가 개시된다. 본 발명의 실시 예에 따른 하이브리드 자동차의 동력전달장치는 주 동력원인 엔진과, 동력분기수단인 유성기어세트와, 보조 동력원인 제1, 제2 모터/제너레이터가 동일 축선상으로 배치되고, 상기 엔진의 회전동력과 제2 모터/제너레이터의 회전동력이 각각 독립된 경로를 통해 디프렌셜을 포함하는 종감속 기어로 전달되는 하이브리드 자동차의 동력전달장치에 있어서, 상기 유성기어세트는 선기어가 제1 모터/제너레이터와 제1 모터축을 통해 직접 연결됨과 동시에 변속기 하우징과 선택적으로 연결되고, 유성 캐리어가 엔진의 입력축과 직접 연결됨과 동시에 원웨이 클러치와 토크 리미터를 개재시켜 변속기 하우징에 연결되며, 링기어가 출력요소로서 제1 출력기어와 직접 연결되어 제1 중간축을 통해 종감속 기어와 연결되며, 상기 제2 모터/제너레이터는 제2 모터축을 통해 제2 출력기어와 직접 연결되어 제2 중간축을 통해 종감속 기어와 연결된다.
