도 6은 본 발명의 다른 실시예를 도시한 도면이다.
도 1을 참조하면, 본 발명 하이브리드 차량용 동력전달 장치의 실시예는, 유성기어장치(PG)와; 상기 유성기어장치(PG)의 한 회전요소에 차례로 연결되는 제1모터제너레이터(MG1) 및 엔진(E)과; 상기 유성기어장치(PG)의 다른 한 회전요소에 연결되는 제2모터제너레이터(MG2)와; 상기 유성기어장치(PG)의 나머지 한 회전요소에 차례로 연결되는 제2클러치(CL2) 및 제2구동기어(DG2)와; 상기 제1모터제너레이터(MG1)가 연결된 회전요소에 차례로 연결되는 제1클러치(CL1) 및 제1구동기어(DG1)와; 상기 제1구동기어(DG1) 및 제2구동기어(DG2)에 각각 치합되는 제1피동기어(PG1)와 제2피동기어(PG2)를 구비한 출력축(OUT)을 포함하여 구성된다.
상기 제1모터제너레이터(MG1)가 연결된 회전요소에는 회전을 구속할 수 있는 브레이크(BK1)가 더 구비된 구성이다.
상기 유성기어장치(PG)의 회전요소들 중, 상기 엔진(E)에 연결된 회전요소는 링기어(R)이고, 상기 제2클러치(CL2)에 연결된 회전요소는 캐리어(C)이며, 상기 제2모터제너레이터(MG2)에 연결된 회전요소는 선기어(S)이다.
즉, 상기 유성기어장치(PG)의 링기어(R)에는 상기 제1모터제너레이터(MG1)와 엔진(E)이 차례로 연결됨과 아울러 상기 제1클러치(CL1)와 제1구동기어(DG1)가 차례로 연결되어, 상기 엔진(E)의 동력은 제1모터제너레이터(MG1)를 통하여 또는 제1모터제너레이터(MG1)의 동력과 함께 상기 유성기어장치(PG)의 링기어(R)를 구동하고, 이 동력은 상기 제1클러치(CL1)가 연결되면 상기 제1구동기어(DG1)에 전달될 수 있도록 구성된 것이다.
또한, 상기 유성기어장치(PG)의 캐리어(C)에는 상기 제2클러치(CL2)와 제2구동기어(DG2)가 차례로 연결되어 있으므로, 상기 제2클러치(CL2)가 연결된 상태에서는 상기 캐리어(C)의 동력이 상기 제2구동기어(DG2)로 전달될 수 있게 된 것이다.
또한, 상기 유성기어장치(PG)의 선기어(S)에는 상기 제2모터제너레이터(MG2)가 연결되어 있어서, 상기 제2모터제너레이터(MG2)로부터의 동력이 직접 상기 유성기어장치(PG)를 통해 상기 제1클러치(CL1)를 통한 제1구동기어(DG1) 또는 제2클러치(CL2)를 통한 제2구동기어(DG2)로 전달될 수 있도록 된 것이다.
한편, 상기한 바와 같이 상기 링기어(R)는 변속기케이스에 브레이크(BK1)로 그 회전을 구속할 수 있도록 구성되어, 상기 브레이크(BK1)는 상기 제1클러치(CL1) 및 제2클러치(CL2)와 함께 도 2에 도시된 바와 같은 조합으로 작동되어, 도 2에 표시한 바와 같은 차량의 운전모드를 구현할 수 있도록 한다.
상기 제1구동기어(DG1)와 제1피동기어(PG1) 사이의 기어비는 상기 제2구동기어(DG2)와 제2피동기어(PG2) 사이의 기어비와 다르게 형성되어, 상기 유성기어장치(PG)가 제공하는 기어비와 함께 차량에 필요한 적절하고 다양한 변속비를 형성하여 차량이 보다 다양한 주행 조건에서 최적의 주행 상태를 구현할 수 있도록 한다.
도 3은 상기한 바와 같은 동력전달장치가 모터의 동력으로만 주행을 하는 EV모드를 구현하는 상태를 도시한 레버선도로서, 브레이크(BK1)가 상기 링기어(R)의 회전을 억제한 상태에서 제2모터제너레이터(MG2)의 동력으로만 주행저항을 극복하고 차량이 구동되는 상황을 나타내고 있다.
이때, 상기 제1클러치(CL1)는 해제되고 제2클러치(CL2)만 체결된 상태이며, Tmg2는 제2모터제너레이터(MG2)가 선기어(S)를 통해 유성기어장치(PG)에 제공하는 토크를 의미하고, 캐리어(C)를 통해 구동륜으로 인출되는 동력이 주행저항과 균형을 이루는 상황을 나타낸다.
도 4는 상기 동력전달장치가 엔진(E)과 모터의 동력을 함께 이용하여 차량을 구동시키는 HEV모드를 설명한 것으로서, 기본적으로 브레이크(BK1)와 제1클러치(CL1)는 해제되고 제2클러치(CL2)가 체결된 상태로서, 엔진(E)과 제1모터제너레이터(MG1)의 동력이 링기어(R)를 통해 유성기어장치(PG)로 제공되고, 제2모터제너레이터(MG2)의 동력이 선기어(S)를 통해 유성기어장치(PG)로 제공되어, 상기 캐리어(C)를 통해 주행저항을 극복하면서 차량의 구동되는 상황을 의미한다.
여기서, 상기 엔진(E)의 토크는 Te로 표시되고, 제1모터제너레이터(MG1)의 토크는 Tmg1으로 표시되어 있는데, 상기 Tmg1의 화살표가 하측방을 향하는 것은 제1모터제너레이터(MG1)가 토크를 흡수하여 발전을 하는 상황을 의미하는 것으로 도 2의 HEV모드 1에 상당한다.
물론, 상기 제1모터제너레이터(MG1)는 상기와 같이 발전을 수행할 수도 있지만, 모터로 기능하여 엔진(E)토크에 더해지는 토크를 제공하도록 할 수도 있고, 아무런 기능을 하지 않고 자유회전하는 상태도 가능한 바, 도 2의 HEV모드 2는 상기 제1모터제너레이터(MG1)가 비발전 상태로 자유회전하는 상태이며, HEV모드 3은 상기 제1모터제너레이너가 모터로서 토크를 유성기어장치(PG)에 제공하는 상태를 의미하는 바, 큰 구동력이 요구되거나 가속이 필요한 상황에 사용될 수 있다.
도 5는 상기 동력전달장치가 엔진(E)의 동력만으로 차량을 구동시키는 엔진(E)모드를 설명한 것으로서, 상기 브레이크(BK1)는 해제되고 제1클러치(CL1)가 체결되며, 제2클러치(CL2)는 해제된 상태로서, 엔진(E)의 동력이 링기어(R)와 제1클러치(CL1)를 통해 구동륜으로 전달되는 상태이다.
이때에도 상기 HEV모드와 유사하게 상기 제1모터제너레이터(MG1)를 자유회전체나 발전기 또는 모터로 기능하도록 할 수 있는 바, 그 형태에 따라 차례로 도 2에 엔진(E)모드 1, 엔진(E)모드 2, 엔진(E)모드 3으로 표시되어 있다.
이와 같은 엔진(E)모드에서, 상기 엔진(E)의 동력은 상기 제1구동기어(DG1)와 제1피동기어(PG1)가 형성하는 고정된 기어비로 운전되어 비교적 높은 차속에서 엔진(E)이 효율이 우수한 영역에서 안정되게 운전될 수 있도록 함으로써 차량의 연비를 향상시킬 수 있게 한다.
한편, 도 6에는 본 발명의 다른 실시예를 도시하고 있는 바, 다른 구성은 도 1의 실시예와 동일하고, 상기 엔진(E)과 제1모터제너레이터(MG1) 사이에 제3클러치가 더 구비되어 서로의 연결상태를 단속할 수 있도록 구성된 점이 다르다.
따라서, 이와 같은 실시예에서는 상기 제3클러치를 체결한 상태에서는 상기 도 1의 실시예와 동일하게 기능하지만, 제3클러치를 해제한 상태에서는 엔진(E)이 격리되므로, 상기 제1모터제너레이터(MG1)와 제2모터제너레이터(MG2)를 동시에 구동하여 구현하는 별도의 EV모드를 구현할 수 있다.
본 발명은 특정한 실시예에 관련하여 도시하고 설명하였지만, 이하의 특허청구범위에 의해 제공되는 본 발명의 기술적 사상을 벗어나지 않는 한도 내에서, 본 발명이 다양하게 개량 및 변화될 수 있다는 것은 당업계에서 통상의 지식을 가진 자에게 있어서 자명할 것이다.
