Abstract

본 발명은 주행 피칭(Pitching) 완충기능을 구비한 스키드 스티어 로더(SKID STEER LOADER)에 관한 것으로서, 특히 스키드 로더가 고르지 못한 노면을 통과할 때 발생하는 피칭현상을 완화시켜 차체의 평형을 유지하기 위한 주행 피칭 완충기능을 구비한 스키드 로더에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skid steer loader having a traveling pitching damping function, and in particular, to alleviate the pitching phenomenon that occurs when the skid loader crosses an uneven road surface to maintain body balance. A skid loader having a traveling pitching buffer function.

본 발명의 주행 피칭 완충기능은 리프트 실린더와 유량 및 방향 제어밸드 상이에 피칭감쇄 스위치, 전기절환밸브 및 어큐무레이터를 설치하여 울퉁불퉁한 노면 주행시 장비의 하중에 의해 리프트 실린더의 상,하 운동을 유발시키는 압유를 전기절환밸브의 제어에 의해 어큐무레이터로 축압시킴으로써 스키드 로더의 피칭현상을 완충시킨다.The driving pitching buffer function of the present invention installs a pitching damping switch, an electric switching valve, and an accumulator between the lift cylinder and the flow and direction control valves, causing the lift cylinder to move up and down by the load of the equipment during uneven road driving. The pressurized oil to be accumulated in the accumulator is controlled to control the electric switching valve to buffer the pitching phenomenon of the skid loader.
