상기 동기장치(SS)는 종래의 싱크로메시방식이 사용될 수 있으며, 도면에서는 중립상태로부터 좌측으로 이동하면, 상기 제1입력축(IN1)의 동력을 상기 제1구동기어(D1)로 전달할 수 있고, 우측으로 이동하면, 상기 제1입력축(IN1)의 동력을 제2입력축(IN2)으로 전달하여, 결과적으로 엔진(E)의 동력으로 모터(M)를 구동하여 모터(M)에 의한 발전이 가능하도록 구성되어 있다.The synchronizing device SS may be a conventional synchronous meshing type. In the drawing, when the synchronizing device SS moves from the neutral state to the left, it can transmit the power of the first input shaft IN1 to the first driving gear D1, The power of the first input shaft IN1 is transmitted to the second input shaft IN2 and consequently the motor M is driven by the power of the engine E, .
상기한 바와 같이 구성된 본 발명 파워트레인은 도 2 내지 도 4에 도시된 엔진(E)의 동력만으로 구동되는 3개의 변속단과, 도 5와 도 6에 도시된 모터(M)의 동력만으로 구동되는 2개의 변속단 및 도 7 내지 도 10에 도시된 4개의 하이브리드모드를 구현할 수 있어서, 비교적 적은 구성부품으로 경량의 간단한 구성을 가지면서도, 다양한 변속비를 제공할 수 있어서, 차량의 연비 향상에 유리한 조건을 제공한다.The power train of the present invention constructed as described above has three gear stages driven only by the power of the engine E shown in Figs. 2 to 4 and two gear stages driven by only the power of the motor M shown in Figs. 5 and 6 7 to 10, so that it is possible to provide various transmission ratios while having a lightweight simple configuration with a relatively small number of components, thereby providing a favorable condition for improving the fuel economy of the vehicle to provide.
도 2는 엔진(E)1단을 도시한 것으로서, 동기장치(SS)가 상기 제1구동기어(D1)에 결합되어 있어서, 엔진(E)의 동력은 상기 제1구동기어(D1), 제1피동기어(P1)를 통해 출력축(OUT)으로 전달된다.2 shows a first stage of the engine E in which a synchronizing device SS is coupled to the first driving gear D1 so that the power of the engine E is transmitted to the first driving gear D1, 1 driven gear P1 to the output shaft OUT.
