Abstract

본 발명은 스키드 스티어 로드용 유압시스템에 관한 것으로, 차량을 구동시키기 위한 구동유압시스템과 작업장치를 작동시키기 위한 작업장치 유압시스템을 하나로 통합하여, 하나의 대용량 가변토출형 유압펌프(1)를 사용하고, 이 유압펌프(1)에서 토출되는 압유가 좌우 구동모우터(3,4)와 다수개의 작업용 액튜에이터(5,6) 및 어태치먼트용 액튜에이터(7)를 선택적으로 작동시키기 위한 콘트롤밸브 유니트(14)와 연결되어 있으며, 상기 콘트롤밸브 유니트(14)를 거쳐 나온 압유가 오일냉각기(15)와 필터(16)를 거쳐 오일탱크(1)로 귀환되어지게 하는 한편, 상기 콘트롤밸브 유니트(14)에 설치된 부하감지기와 유압펌프(2)의 토출유량제어기(23)가 연결된 구조로 이루어져, 사이 유압펌프(2)를 대용량의 것으로 사용하므로써 큰 힘이 필요한 액튜에이터를 사용하는 경우에도 별도의 유압펌프를 설치할 필요가 없고, 또한 액튜에이터에 부가되는 부하의 크기에 따라 유압펌프(2)의 토출 유량이 자동적으로 제어되어지게 하는 효과가 있게 한 것이다.
