Description

휠(Wheel)형 중장비의 로드 서스펜션 시스팀(Load Suspension System)Wheel Suspension System of Wheel Type Heavy Equipment

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명의 유압 계통도.2 is a hydraulic system diagram of the present invention.

Claims (1)

유압을 동력원으로 하여 주행과 채굴작업을 복합적으로 실시하는 휠형 중장비에 있어서, 작업라인에 어큐뮬레이터(7)를 설치하고 유압 엑튜에이터와 어큐뮬레이터(7)를 개폐토록한 유압밸브(4)에 체크밸브 기능을 첨가시켜, 어큐뮬레이터(7)로 부터 아암실린더(5)에 오일이 자동적으로 유출되게 하므로써 서스펜션 시스팀이 온되었을때 아암이 순간적으로 다운됨을 방지하는 한편 체크(cheek)의 오프닝(opening)을 조절토록 하므로써 원활한 서스펜션이 이루어지도록 한 휠형 중장비의 로드 서스펜션 시스팀.In wheel type heavy equipment which combines traveling and mining operations using hydraulic power as a power source, an accumulator (7) is installed in a work line and a hydraulic valve (4) check valve functions to open and close the hydraulic actuator and the accumulator (7). By adding oil to the arm cylinder (5) from the accumulator (7) to prevent the arm from momentarily down when the suspension system is turned on, while adjusting the opening of the check. The wheel suspension system of the wheel type heavy equipment which made the suspension smooth by doing so. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
