The forward clutch is operated in the forward condition of the vehicles including the continuously variable transmission. The reverse break is the element operated in the backward state. The first flow channel(107) is used in order to apply the first fluid pressure to the manual valve. The second fluid path(109) is formed in order to output the first fluid pressure with the forward clutch. The third flow channel(110) is formed in order to input the second fluid pressure with the manual valve. The fourth flow channel(111) is formed to output the second fluid pressure by the forward clutch.

Abstract: 본 발명은 무단 변속기의 유압제어시스템에 관한 것으로서,
금속벨트를 매개로 하여 무단 변속을 수행하는 구동풀리와 종동 풀리에 가변 라인압을 각각 독립적으로 공급하는 독립압력제어 밸브를 갖춘 무단 변속기의 유압회로에 있어서,
상기 독립압력 제어 밸브는 저단 변속시 종동 풀리에 공급되는 압력은 라인압을 제어하여 종동 풀리 요구 압력으로 공급하고, 구동풀리 압력은 라인압으로 부터 감압된 압력을 조절하여 상기 구동풀리로 공급하는 유로를 형성하며, 고단 변속시 구동풀리에 공급되는 압력은 라인압력을 제어하여 구동풀리 요구압력으로 공급하고, 종동풀리 압력은 라인압으로 부터 감압된 압력을 조절하여 종동풀리로 공급하는 유로를 형성함으로서, 종동 풀리는 라인압을 그대로 이용할 수 있도록 좌측의 제1 피드 백 포트가 닫힘상태가 되고, 압력 조절이 필요시 구동 풀리측은 제2 피드백 포트가 열리게 되어 압력 피드 백이 가능하여 압력 조절이 가능하며, 스풀밸브 및 솔레노이드 밸브의 추가 없이도 독립압력제어방식을 구현할 수 있어, 차량의 제조원가를 절감할 수 있는 효과가 있다.
