TRAVELING CONTROL MECHANISM AND TRAVELING CONTROL METHOD OF HYDRAULIC DRIVEN CONSTRUCTION MACHINE
To provide a traveling control mechanism and a traveling control method capable of controlling a traveling mechanism in consideration of operation contents of a remote control valve.SOLUTION: A traveling control mechanism is provided with remote control valves 21 to 24; pressure adjusting solenoid valves 61 to 62; a setting mechanism 70; and a controller 60, and can switch traveling speed between high-speed and low-speed according to the operation amount of the remote control valves. An HST circuit 30 is provided with a pump and a traveling motor, and a pilot line in which working fluid flows from the remote control valves is connected to the pump. A pressure sensor is attached to the pilot line, and a rotation sensor is attached to a traveling motor. The controller controls the pressure of the working fluid supplied from the remote control valves independently from manual operation of the remote control valves on the basis of set signals, pressure signals, and rotation speed signals. The remote control valves control a flow rate of the working fluid discharged from the pump by changing pressure in the pilot line or keeping that constant.SELECTED DRAWING: Figure 2
