Abstract
차량의 엔진(2)과 변속장치(4) 사이의 자동작동 클러치(3)가 유압식 작동기(8)에 의해 이동되고, 이것이 맞물림분리된 클러치에 작용하여 완전 분리위치로부터 클러치 미끄럼이 일어나는 위치들을 지나 완전히 맞물린 위치로 클러치를 이행시킨다. 엔진토오크가 전달되기 시작하는 클러치의 접촉점이 정해지고 대응하는 작동기(8)의 위치가 기억된다. 토오크가 전달되지 않는 접촉점 상부의 영역에서는 작동기의 위치가 위치조절회로(70)에 의해 조절되는 한편, 토오크가 전달되는 접촉점 하부의 영역에서는, 엔진 속도조절회로(78)가 작동기 위치 조절회로에 중복되어 있다. 접촉점에서의 엔진속도는 클러치(출력)축의 속도를 약간(50 r.p.m) 상회하는 값에 조정된다. 작동기(8)는 속도조절회로(78)가 중복되어 있는 위치조절회로(70)에 의해 접촉점에 대응하는 위치에 조정된다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 차량에 설치되는 본 발명의 자동 클러치제어장치를 가진 대략적 구동부품 및 작동부품의 개략도이다.
Claims (8)
- 차량의 엔진(2)과 변소장치(4) 사이에 배치되고 있고, 완전히 분리된 위치와 미끄럼이 일어나는 위치들 사이에서 분리기(41)를 이동시키는 작동기(8)에 의해 완전히 압입된 위치로 이동되는 자동작동 클러치의 제어장치로서, 엔진토오크가 전달되기 시작하는 클러치의 접촉점(T)이 조사되고 이 접촉점에 있어 작동기의 축방향 위치가 기억되는 자동 작동되는 클러치의 제어장치에 있어서, -토오크가 전달되지 않는 접촉점(T) 상부의 영역에 있어서는, 작동기의 위치는 위치조절회로(7O)에 의해 조절되고, -토오크가 전달되는 접촉점(T) 하부의 영역에 있어서는, 작동기에 대한 위치조절회로에 엔진에 대한 회전수조절회로(78)가 중접되어 있는 것을 특징으로 하는 제어장치.
- 제1항에 있어서, 접촉점(T)에서의 엔진회전수는 회전수조절회로(78)에 의해 변속장치의 입력축의 회전수를 초과하는 값에 조절되며, 이들 두 회전수간의 차는 차량의 작동모드(출발,기어전환,구동 추진)에 의존하는 것을 특징으로 하는 제어장치.
- 제1항에 있어서, 차량의 추진구동의 경우 접촉점(T)의 엔진회전수는 회전수조절회(78)에 의해 클러치출력축의 회전수를 약간 하회하는 회전수에 조절되는 것을 특징으로 하는 제어장치.
- 제1항에 있어서, 차량이 추진작동되고 엔진회전수가 소정의 회전수차만큼 변속장치(4)의 구동축의 회전수를 하회하는 경우, 작동기의 위치가 위치조절회로(70)에 의해, 클러치(36)에 의해 전달되는 토오크가 제동 엔진토오크와 같도록, 조절되는 것을 특징으로 하는 제어장치.
- 제2항에 있어서, 운행작동에 있어 회전수차가 약 50r.p.m인 것을 특징으로 하는 제어장치.
- 제1항에 있어서, 작동기(8)의 조절된 위치가 각 순간 측정되고 그 측정치가 저역필터링되고 기억되는 것을 특징으로 하는 제어장치.
- 제6항에 있어서, 각 순간의 엔진회전수에 의존하는 엔진의 토오크도표로부터 추출된 필터링된 측정치의 조절편차에 의해 접촉점(T)에 대한 검정치(보정치)가 결정되는 것을 특징으로하는 제어장치.
- 제1항에 있어서, 위치조절회로(7O)에 전류조절회로(58)가 중복되어 있는 것을 특징으로 하는 제어장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
