The present invention relates to a power transfer system for a hybrid electric vehicle, which eliminates the engine clutch, uses a low-loss, low-cost power control means, improves power transfer composition, and enhances driving efficiency in EV mode and parallel mode. To achieve this, disclosed is a power transfer system for a hybrid electric vehicle, comprising: an engine; a first motor which operates for driving the vehicle or operates as a power generator by receiving power of the engine; a first power transfer instrument which is placed in between the engine and the first motor to transfer the power of the engine to the first motor; a second power transfer instrument which is placed in between the first motor and a driving shaft of a driving wheel, which operates to transfer the power of the engine, which is transferred to the first motor, or the power of the engine and the power of the first motor to the driving shaft of the driving wheel, or operates to block the power in between the first motor and the driving shaft of the driving wheel; and a second motor which is connected to transfer the power to the second power transfer instrument with a fourth power transfer instrument as the medium, which outputs power for driving the vehicle, and which transfers the power to the driving shaft of the driving wheel through the fourth power transfer instrument and the second power transfer instrument.

    본 발명은 하이브리드 자동차용 동력 전달 시스템에 관한 것으로서, 엔진 클러치를 삭제하고 저손실 및 저비용의 동력단속수단을 대체 사용하여 동력 전달 구성을 개선함으로써 EV 모드 및 병렬 모드 주행시의 주행 효율을 개선할 수 있는 하이브리드 자동차용 동력 전달 시스템을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 엔진; 차량 구동을 위한 모터로 작동하거나 엔진 동력을 전달받아 발전기로 작동하는 제1모터; 상기 엔진과 제1모터 사이에 구성되어 엔진 동력을 제1모터에 전달하는 제1동력전달기구; 상기 제1모터와 주행휠의 구동축 사이에 구성되어, 상기 제1모터로 전달된 엔진 동력 또는 상기 엔진 동력과 제1모터의 동력을 주행휠의 구동축에 전달하도록 작동되거나, 상기 제1모터와 주행휠의 구동축 사이에 동력을 차단하도록 작동되는 제2동력전달기구; 및 상기 제2동력전달기구에 제4동력전달기구를 매개로 하여 동력 전달 가능하게 연결되고 차량 구동을 위한 동력을 출력하여 제4동력전달기구 및 제2동력전달기구를 통해 상기 주행휠의 구동축에 전달하는 제2모터를 포함하는 하이브리드 자동차용 동력 전달 시스템이 개시된다.
