Description

휠타입 굴삭기의 주행 속도계Travel speedometer on wheel type excavator

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

제1도는 주행속도계 전체의 간략한 구성도.1 is a simplified configuration diagram of the entire speedometer.

제3도는 조속기와 감압 밸브의 관련 상세도.3 is a related detail view of the governor and the pressure reducing valve.

제4도는 변속기 주축과 조속기의 변위 도표.4 is a displacement chart of the transmission spindle and the governor.

Claims (1)

조속기(30)의 입력축(31)을 변속기 주축에 접속 회전시키고, 조석기의 진퇴축(34)을 감압 밸브(40)의 푸쉬로(41)에 접속하며, 기어펌프의 압유를 감압밸브(40)의 1차측포트(43)에 공급하여 2차측 출력포트(44)에서 속도에 비례하는 파이로트 압력 발생하고, 2차측 포트의 파이로트 압력을 속도계에 접속하여 구성된 휠 타입 굴삭기의 주행 속도계.The input shaft 31 of the governor 30 is connected and rotated to the transmission main shaft, and the advance and retreat shaft 34 of the tide machine is connected to the pusher 41 of the pressure reducing valve 40, and the pressure oil of the gear pump is reduced to the pressure reducing valve 40. A traveling speedometer of a wheel type excavator configured to supply to the primary side port 43 of the ()) and generate a pilot pressure proportional to the speed at the secondary side output port 44 and connect the pilot pressure of the secondary side port to a speedometer. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
