The present invention comprises: a first rotor shaft which is concentrically connected with an output shaft of an engine and which is connected with a rotor of a first motor; an engine clutch shaft which is concentrically connected with the first rotor shaft so that rotation is constrained and which is connected with the engine clutch; a transmission input shaft which is concentrically installed with the engine clutch shaft, wherein rotation is constrained by a rotor of a second motor connected with the engine clutch; and a cooling flow path which is formed at the transmission input shaft to supply oil for cooling the first motor, the second motor, and the engine clutch at the same time. A vehicle hybrid powertrain cooling structure improves durability of a vehicle and secures stabilized power transmission performance by efficiently cooling the first motor, the second motor, and the engine clutch.

    본 발명은 엔진 출력축에 동심축을 이루며 연결되고, 제1모터의 로터에 연결된 제1로터샤프트; 상기 제1로터샤프트에 회전이 구속되도록 동심축을 이루어 연결되고 엔진클러치에 연결된 엔진클러치샤프트; 상기 엔진클러치에 연결된 제2모터의 로터에 회전이 구속되고, 상기 엔진클러치샤프트에 동심축을 이루어 설치된 변속기입력축; 상기 제1모터와 제2모터 및 엔진클러치를 동시에 냉각시키는 오일을 공급할 수 있도록 상기 변속기입력축에 형성된 냉각유로를 포함하여 구성된다.
