Description

하이브리드 차량용 동력전달장치{POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE}
본 발명은 하이브리드 차량용 동력전달장치에 관한 것으로서, 보다 상세하게는 이중 모터가 적용되더라도 전장을 축소할 수 있는 하이브리드 차량용 동력전달장치에 관한 것이다.
일반적으로 하이브리드 차량용 동력전달장치는 자동변속기, 모터, 엔진 및 ISG(Integrated Startor & Generator)가 일렬로 배열되는 레이아웃을 갖는다.
엔진과 모터를 이용한 하이브리드 자동차에서는 모터를 사용하여 차량의 초기 출발을 도모하고 차량이 일정속도를 갖게 되면 제너레이터, 즉 ISG가 엔진을 시동하여 엔진의 출력과 모터의 출력을 동시에 이용하게 된다.
한편, 하이브리드 차량용 전달장치에서 사용되는 모터는 전기 주행을 초기 엔진이 구동되지 않을 때 차량 전기 주행을 위해 구동될 수 있다.
그리고, 최근에는 모터가 1개로 한정되지 않고 2개 이상이 복수개로 배치된다. 일예로, 하이브리드 차량용 동력전달장치에서 2개의 모터가 배치되는 경우, 제1모터는 엔진 시동을 위해 구동되고, 제2모터는 차량 전기 주행을 위해 구동될 수 있다.
그러나, 종래에는 엔진 구동력에 의한 충격을 흡수하기 위해 필수적으로 사용되는 토션댐퍼가 모터와 엔진 사이에 배치되므로, 하이브리드 차량용 전달장치의 전장이 길어지고, 토션댐퍼를 지지하기 위한 별도의 중량물이 설치되어야 하는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.
본 발명의 배경기술은 대한민국 공개특허공보 제2009-0020791호(2009.02.27. 공개, 발명의 명칭 : 하이브리드 차량용 동력전달장치)에 게시되어 있다.

그리고, 제1모터부(21)의 내부에 제1로터부(31)를 배치시킨다. 이때, 제1모터부(21)는 커버외벽부(11)의 내측에 장착되고, 제1로터부(31)는 커버내벽부(12)에 지지된다.
또한, 엔진부(100)와 제1댐퍼부(41)를 결합한 후, 제1댐퍼부(41) 및 제2댐퍼부(42)를 제1로터부(31)의 내부에 배치시킨다. 이때, 제2댐퍼부(42)는 전달부(50)와 스플라인 결합되고, 제1댐퍼부(41)는 제1로터부(31)와 용접된다.
상술한 조립 구조는 제1댐퍼부(41)와 제2댐퍼부(42)를 제1모터부(21)의 내부에 배치하여 전장 단축을 기대할 수 있다. 그리고, 제1로터부(31)와 제1댐퍼부(41)가 직접 용접에 의해 연결되므로, 별도의 댐퍼용 매스(mass)가 생략될 수 있다. 즉, 제1댐퍼부(41)에 결합된 제1로터부(31)의 무게가 상당하여 댐퍼용 매스 기능을 수행할 수 있다. 또한, 제1댐퍼부(41)와 제2댐퍼부(42)가 이중으로 연결된 구조를 채택하여 저강성화가 가능하다. 이로 인해 제1댐퍼부(41)의 무게를 줄이고 구조를 단순화할 수 있다.
한편, 제2모터부(22)가 구동되면 제2로터부(32)가 회전되고, 클러치부(60)와 연결된 출력부(70)가 제2로터부(32)의 회전력을 변속기(200)에 전달하여 차량이 주행할 수 있다.
그리고, 제1모터부(21)가 구동되면, 제1로터부(31)가 회전되고, 제1로터부(31)와 연결된 제1댐퍼부(41)가 엔진부(100)를 회전시켜 엔진부(100)의 시동을 유도할 수 있다.
엔진부(100)가 구동되면, 엔진부(100)의 회전력이 제1댐퍼부(41) 및 제2댐퍼부(42)를 통해 전달부(50)에 전달되고, 클러치부(60)를 통해 출력부(70)로 이동되어 차량 주행이 실시될 수 있다.
본 발명의 일 실시예에 따른 하이브리드 차량용 동력전달장치(1)는 모터부(20)의 내부에 토션댐퍼부(40)가 배치되므로 전장 길이 축소가 가능하고, 토션댐퍼부(40)가 엔진부(100) 및 모터부(20)의 충격을 완화할 수 있다.
본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.
