The present invention relates to a powertrain for a vehicle, in which an engine is multi-staged while simplifying a transmission structure. The powertrain for the vehicle introduced in the present invention comprises: a first input shaft receiving a rotary force from a first motor and the engine; a second input shaft receiving the rotary force from a second motor; an output shaft disposed parallel to the first input shaft and the second input shaft; a transmission gear set in which a plurality of gear sets having different gear ratios are meshed with the first input shaft and the output shaft, and a gear set suitable for a driving speed is selected by an intermittent element; and a motor-side transmission gear set meshingly coupled to the second input shaft and the output shaft.

    본 발명은 변속기 구조를 단순화하면서 엔진을 다단화한 차량용 파워트레인에 관한 것으로, 본 발명에서는, 제1모터와 엔진으로부터 회전력을 제공받는 제1입력축; 제2모터로부터 회전력을 제공받는 제2입력축; 상기 제1입력축 및 제2입력축과 나란하게 배치된 출력축; 상기 제1입력축과 출력축에 기어비를 달리하는 복수의 기어세트가 치합 결합되고, 단속요소에 의해 주행속도에 맞는 기어세트가 선택되는 변속기어세트; 및 상기 제2입력축과 출력축에 치합 결합되는 모터측 전달기어세트;를 포함하는 차량용 파워트레인이 소개된다.
