Abstract

본 발명은 주행가능한 각종 건설 중장비의 주행 중 작업장치를 조작하더라도 주행의 직진성을 계속 유지할 수 있도록 하는 장치에 관한 것이다. 본 발명의 직진주행장치는, 주행가능한 중장비의 주행중 작업장치를 조작하게 되면 어느 한 유압펌프의 토출유량이 좌측 및 우측 주행모터에 균등 분배되어 공급되도록 하고 다른 한 유업펌프의 토출유량이 조작된 작업장치에 공급되도록 함으로써 중장비의 직진주행성을 얻는 중장비의 직진주행장치에 있어서, 상기 좌측 및 우측 주행모터의 동시작동 및 단독작동 여부를 감지하는 수단을 포함함에 따라, 상기 좌측 및 우측 주행모터가 동시작동될 때에만 기능을 발휘하도록 됨을 특징으로 한다The present invention relates to an apparatus for maintaining the straightness of the driving even when operating the work device while driving the various construction of heavy equipment capable of running. In the straight traveling device of the present invention, when the work device is operated while driving heavy equipment, the discharge flow rate of one hydraulic pump is equally distributed to the left and right driving motors, and the discharge flow rate of the other dairy pump is operated. A straight traveling apparatus of a heavy equipment which obtains a straight running capability of heavy equipment by being supplied to a device, the means comprising detecting means for simultaneous and independent operation of the left and right traveling motors, such that the left and right traveling motors operate simultaneously. To function only when
