Description

차량 드라이브라인 시스템
본 발명은 차량용 차량 드라이브라인 시스템에 관한 것이다. 더 구체적으로는, 본 발명은 차동장치용 입력 샤프트에 전기 모터를 선택적으로 연결하도록 구성될 수 있는 차량 드라이브라인 시스템에 관한 것이다.
오늘날의 승용차의 전력 시스템은 12V에 기초한다. 상대적으로 낮은 전압으로 인해, 전기 동력형 추진 유닛 같은 고전력 유틸리티를 위한 제안된 해결책은 높은 손실 및 증가된 케이블 치수를 야기하는 높은 전류를 초래한다.
최근 몇 년 동안, 기존의 12V 시스템에 48V 전력 시스템을 추가하는 경향이 있다. 전력이 증가함에 따라, 새롭고 개선된 해결책이 적용가능할 수 있고, 추가적인 고전력 전자기기를 필요로 하는 이전의 해결책을 대체한다.
이러한 한가지 예는 하이브리드 기술, 즉 기존의 내연기관 구동장치에 전기식 구동장치를 추가하고, 차량을 전기적으로, 내연기관에 의해, 또는 양자 모두에 의해 구동시키는 기술이다. 본 출원인은 예를 들어 WO2010101506 또는 WO2012066035에 기재되어 있는 바와 같은 하이브리드 구동장치를 위한 몇몇 해결책을 앞서 제시하였다. 이들 시스템은 추진 목적을 위한 고전력 전기 모터 및 토크 벡터링(torque vectoring) 목적을 위한 소형 전기 모터를 포함한다. 48V가 이용 가능하다면, 단일 전기 모터와 전기 모터로부터의 토크를 선택적으로 수용하도록 구성되는 차동장치만을 사용하여, 선택가능한 전기적 전체 차륜 구동(all wheel drive)을 가능하게 하는 선택적 전체 차륜 구동 차량을 위한 차량 드라이브라인 시스템을 개발할 수 있다.
본 발명의 목적은 종래 기술 시스템의 단점을 극복하는 차량 드라이브라인 시스템을 제공하는 것이다. 특히, 본 발명의 목적은 연결해제 시스템, 즉 구동트레인의 일부가 드래그 토크(drag torque) 및 과도한 에너지 손실을 감소시키기 위해 연결해제되는 시스템을 위해 사용될 수 있는 차량 드라이브라인 시스템을 제공하는 것이다. 이러한 시스템에 대해, 연결해제 모드로부터 연결 모드로의 모드 변경이 요청될 때, 제안된 해결책이 구동트레인의 고정부를 가속하기 위해 사용될 수 있다. 본 발명은 더 신속한 연결을 허용하여 더 어렵고 심각한 구동 조건에 대해서도 개선된 성능을 허용할 뿐만 아니라, 신속한 응답 및 토크 정확도의 관점에서의 전체 차륜 구동 클러치의 통상적으로 매우 높은 요건을 감소시킬 수 있다.
다른 목적에 따르면, 전체 차륜 구동 클러치 및 연결해제 도그 클러치를 갖는 전체 차륜 구동 구성에서 제안된 드라이브라인 시스템을 구현하는 것이 가능하고, 따라서 이들 가용한 클러치는 전기 모터를 연결해제하기 위해 사용될 수 있다.
제1 양태에 따르면, 차량 드라이브라인 시스템이 제공된다. 시스템은 차동장치에 구동 토크를 제공하도록 구성된 피니언, 및 감속 기어장치를 통해 피니언에 연결되어 있는 전기 모터를 포함한다.
일 실시예에서, 전기 모터는 상기 피니언 상에 동축으로 배열된다. 또한, 감속 기어장치는 유성 기어 세트를 포함할 수 있다.
전기 모터는 상기 유성 기어장치의 태양 휠을 구동할 수 있고, 피니언은 상기 유성 기어장치의 유성 캐리어에 연결된다.
차량 드라이브라인 시스템은 전기 모터를 상기 감속 기어장치에 선택적으로 연결하기 위한 커플링을 더 포함할 수 있다.
일 실시예에서, 전기 모터는 상기 피니언과 반경 방향으로 오프셋되어 배열된다. 감속 기어장치는 기어열을 포함할 수 있다.
일 실시예에서, 차량 드라이브라인 시스템은 피니언 상에 제공되는 디스크 클러치를 더 포함한다.
제2 양태에 따르면, 차량용 전체 차륜 구동 시스템이 제공된다. 전체 차륜 구동 시스템은 엔진에 의해 구동되는 제1 구동트레인, 전체 차륜 구동을 제공하기 위해 제1 구동트레인에 선택적으로 연결되는 제2 구동트레인, 및 차량이 2륜 구동 모드에 있을 때 제1 구동트레인 및 제2 구동트레인으로부터 선택적으로 연결해제되는 중간 구동트레인을 포함하고, 상기 중간 구동트레인은 선행 청구항들 중 어느 하나에 따른 차량 드라이브라인 시스템을 포함한다.
차량 드라이브라인 시스템은 전기 모터를 활성화시킴으로써 전체 차륜 구동이 요구될 때 중간 구동트레인을 가속시키도록 구성될 수 있다.
본 발명은 첨부 도면을 참조하여 이하에서 더 상세하게 설명될 것이다.
도 1은 실시예에 따른 차량 드라이브라인 시스템의 개략도이다.
도 2는 실시예에 따른 차량 드라이브라인 시스템의 개략도이다.
도 3은 실시예에 따른 차량 드라이브라인 시스템의 개략도이다.
도 4는 실시예에 따른 차량 드라이브라인 시스템의 개략도이다.
도 5는 실시예에 따른 차량 드라이브라인 시스템의 개략도이다.
도 1에서, 본 발명의 실시예에 따른 차량 드라이브라인 시스템을 이용하여 차량 드라이브라인이 도시된다. 차량 드라이브라인은 엔진(도시되지 않음)에 의해 구동되는 전방 액슬(1), 및 엔진으로부터 구동 토크를 수용하는 프로펠러 샤프트(2)를 포함한다. 프로펠러 샤프트(2)는 후방 차동장치(20)와 맞물리는 피니언(10)을 통해 후방 액슬(3)과 연결된다. 도 1에서 볼 수 있는 바와 같이, 차량 드라이브라인은 후방 차동장치(20)와 관련하여 배열된 전체 차륜 구동 클러치(4)에 의해 선택적 4륜 구동을 허용한다. 부가적으로, 2륜 구동 중에 드래그 토크를 감소시키기 위한 연결해제부(5)가 제공된다.
피니언(10)은 또한 후방 액슬(3)의 전방에 종방향으로 위치된 전기 모터(30)로부터 선택적 구동 토크를 수용한다. 전기 모터(30)는, 본 실시예에서, 회전 속도를 희망 비율로 감소시키기 위한 복수의 맞물림 기어를 갖는 기어열에 의해서 구현되는, 감속 기어장치(40)를 통해서 피니언(10)에 연결된다. 미리결정된 구동 기준 또는 운전자의 입력에 기초하여 제어될 수 있는 전기 모터(30)가 가동 중일 때, 차량의 전체 차륜 구동을 제공하기 위해 구동 토크가 후방 액슬(3)에 추가될 것이다. 연결해제부(5) 및 전체 차륜 구동 클러치(4)가 계합되면, 전기 모터(30)는 곧 전체 차륜 구동 차량에 구동 토크를 추가할 것이다. 따라서, 차량 드라이브라인 시스템은 기계적 전체 차륜 구동, 전기적 전체 차륜 구동, 및 기계적 및 전기적 전체 차륜 구동의 조합을 허용한다. 또한, 전술한 바와 같이, 연결해제 모드 중에, 전기 모터(30)는 연결 모드, 즉 전체 차륜 구동 모드로의 더 빠른 변경을 허용하기 위해 구동트레인의 고정 부분을 가속시키도록 작동될 수 있다. 결과적으로, 기존의 도그 클러치(5) 및 전체 차륜 구동 클러치(4)는 전기 모터(30)를 구동트레인으로부터 연결해제하기 위해 제어될 수 있다.
이제, 도 2를 참조하면, 차량 드라이브라인 시스템의 다른 실시예가 도시되어 있으며, 이는 도 1을 참조하여 설명된 실시예와 유사하지만, 여기서는 전체 차륜 구동 클러치(4) 및 연결해제부(5)의 위치가 전환되었다. 따라서, 구동 토크는 전체 차륜 구동 클러치(4)를 통해 엔진으로부터 피니언(10)으로 전달되고, 연결해제부(5)는 후방 액슬(4)의 완전한 연결해제를 허용한다.
전술된 실시예에 대해, 피니언(10)에 연결되는 전기 모터(30)는 차량 드라이브라인 시스템의 전기적인 전체 차륜 구동뿐만 아니라 동기화 목적을 위한 연결해제된 부분들의 가속도 허용할 것이다.
도 3에는, 차량 드라이브라인 시스템의 다른 대안이 도시되어 있으며, 여기서 엔진(도시되지 않음)은 2륜 구동 모드를 위해 후방 액슬(3)을 구동한다. 전달 케이스(50)는 피니언(10)을 통해 전방 액슬(3)을 선택적으로 구동하기 위해 제공된다. 이러한 경우에, 전달 케이스(50)에는, 예를 들어 벨트 구동을 통해서 피니언(10)에 구동 토크를 분배하도록 동작되는 전체 차륜 구동 클러치(4)가 제공된다. 전술한 실시예와 유사하게, 연결해제부(5)가 여기에서 전방 액슬(1) 상에 제공될 수 있다.
전기 모터(30)는 이전의 실시예와 동일한 감속 기어장치(40)를 통해 피니언(10), 즉 전달 케이스(50)의 출력 샤프트에 연결된다. 따라서, 전기 모터(30)는 전기적인 전체 차륜 구동뿐만 아니라 전달 케이스(50)의 전체 차륜 구동 클러치(4)가 계합되는 경우에는 기계적 및 전기적 전체 차륜 구동의 조합을 허용할 것이다.
피니언(10)에 전기 모터(30)를 연결하기 위한 다른 대안들이 도 4 및 도 5에 도시되어 있다. 도 4에서 시작하여, 전기 모터(30)는 상기 피니언(10) 상에 동축으로 배열되고, 전기 모터(30)의 회전자는 유성 기어장치(40)의 태양 기어(42)를 구동하여 감속 기어장치를 형성한다. 태양 기어(42)는 피니언(10)을 둘러싸는 중공 샤프트를 형성하고, 이는 유성 캐리어(44)의 복수의 유성과 맞물린다. 유성 캐리어(44)는 유성 기어장치(40)에 대한 출력 샤프트를 형성하고 피니언(10)을 구동하기 위해 피니언(10)에 연결되어 하류 차동장치(20)에 연결된다. 유성 기어장치(40)의 태양 기어는 로킹될 수 있다.
도 5에서, 유사한 실시예가 도시되어 있지만, 여기에서 전체 차륜 구동 클러치(4)가 차동장치(20)와 전기 모터(30)가 피니언(10)과 연결되는 위치 사이에서 종방향으로 피니언(10) 상에 배열된다. 이것에 추가로, 태양 기어(42)는 예컨대 시프트 슬리브 형태의 클러치(60)를 통해 전기 모터(30)에 연결된다. 이는 전기 모터(30)가 클러치(60)를 통해 피니언(10)에 선택적으로 연결된다는 것을 의미한다.
차량 드라이브라인 시스템이 전체 차륜 구동 시스템과 관련하여 주로 설명되었지만, 제안된 드라이브라인 시스템은 전방 액슬 또는 후방 액슬 상에서 구현될 수 있다는 것을 인식해야 한다. 따라서, 시스템은 전륜 구동 시스템, 후륜 구동 시스템, 또는 전체 차륜 구동 시스템에 사용될 수 있다.
특히 전체 차륜 구동 차량의 경우, 구동트레인은 엔진에 의해 영구 구동되는 구동트레인 부분에 대응하는 제1 구동트레인, 전체 차륜 구동 동안 엔진에 의해 선택적으로 구동되는 제2 구동트레인, 및 전체 차륜 구동 모드에서 제1 구동트레인을 제2 구동트레인에 연결하는 중간 구동트레인으로 분할된다.
도 1을 참조하면, 제1 구동트레인은 전방 액슬(1) 및 하류측 프로펠러 샤프트(2)에 대응한다. 제2 구동트레인은 후방 액슬, 즉 전체 차륜 구동 클러치(4) 하류의 회전 부분에 대응한다. 중간 구동트레인은 연결해제 클러치(5)의 출력부와 전체 차륜 구동 클러치(4)의 입력부 사이에 배치되어 있는 부분에 대응한다. 이 양태에서, 중간 구동트레인에는 전술된 차량 드라이브라인 시스템이 제공되고, 즉 피니언(10) 및 전기 모터(30)는 감속 기어장치(40)를 통해 피니언(10)에 연결된다. 이러한 특정 실시예에서, 차량 드라이브라인 시스템은 전기 모터를 활성화시킴으로써 전체 차륜 구동이 요구될 때 중간 구동트레인을 가속시키도록 구성된다.
본 발명이 특정 실시예들을 참조하여 위에서 설명되었지만, 본 명세서에 설명된 특정 형태로 제한되도록 의도되지 않는다. 오히려, 본 발명은 첨부된 청구 범위에 의해서만 제한된다.
