Abstract
본 발명은 건설기계의 자동화를 이루기 위한 건설기계 주행시스템의 제어장치에 관한 것으로, 본 발명에 의한 제어장치는, 엔진과, 이 엔진에 의해 구동되는 유압펌프 및 파일럿펌프와, 상기 유압펌프의 토출유에 의해 작동되는 주행모터와, 상기 유압펌프와 상기 주행모터의 사이에 설치되어 스프울의 이동에 의한 유로의 절환접속으로 상기 주행모터의 작동을 제어하는 콘크롤밸브와, 운전자의 조작에 따라 상기 콘트롤밸브의 스프울에 상기 파일럿펌프로부터의 파일럿압을 인가하여 상기 상기 스프울을 이동시킴으로써 상기 콘트롤밸브의 작동을 제어하는 주행페달을 구비한 건설기계 주행시스템에 있어서, 상기 주행페달과 별도로 상기 콘트롤밸브의 스프울에 상기 파일럿펌프로부터의 파일럿압을 인가하여 상기 콘트롤밸브의 작동을 제어하는 수단을 구비하며, 상기 주행페달에 의한 상기 콘트롤밸브의 제어는 상기 수단에 의한 상기 콘트롤밸브의 제어에 비해 우선권을 갖는 것을 특징으로 한다.The present invention relates to a control device for a construction machine running system for automating a construction machine. The control device according to the present invention includes an engine, a hydraulic pump and a pilot pump driven by the engine, and a discharge of the hydraulic pump. A driving motor operated by oil, a control valve installed between the hydraulic pump and the driving motor to control the operation of the driving motor by a switching connection of a flow path by the movement of the spring, and according to the driver's operation A construction machine traveling system having a traveling pedal for controlling the operation of the control valve by applying a pilot pressure from the pilot pump to a spring of a control valve to move the spring, the control being separate from the driving pedal. The pilot pressure from the pilot pump is applied to the spring of the valve to control the operation of the control valve. Includes a stage, the control of the control valve by the driving pedal is characterized in that a priority compared to the control of the control valve by said means.
