TRAVELING SYSTEM HYDRAULIC CIRCUIT AND TRAVELING CONTROL METHOD
To provide a traveling system hydraulic circuit and a traveling control method that enable control according to the operation amount of an operation member, a set signal from a setting member, and a rotation speed of a traveling motor.SOLUTION: A traveling system hydraulic circuit is provided with a plurality of operation valves 31, an actuation valve 60, a setting member 61, and a control device 43. A traveling device can switch a traveling speed of a work machine between high speed and low speed, according to an operation amount of each operation valve. The traveling device is provided with traveling pumps 24 and traveling motors 34. In each traveling pump, a second oil path 32 in which working fluid supplied from each operation valve flows is connected to each operation valve. To each traveling motor, a third measuring device 63 measuring a rotation speed of the traveling motor is attached. The control device actuates each operation valve independently from a manual operation of each operation valve so as to adjust a pressure of the working fluid supplied from each operation valve, on the basis of a setting signal from a setting member and a rotation speed signal from each of the third measuring devices. Each operation valve adjusts a flow rate of the working fluid discharged from each traveling pump.SELECTED DRAWING: Figure 4
【課題】操作部材の操作量、設定部材からの設定信号及び走行モータの回転数に応じて制御可能な走行系油圧回路及び走行制御方法を提供する。【解決手段】走行系油圧回路は、複数の操作弁３１、作動弁６０、設定部材６１、制御装置４３が設けられる。走行装置は、各操作弁の操作量に応じ、高速と低速との間で作業機の走行速度を切り換え可能で、走行装置には、走行ポンプ２４と走行モータ３４とを設け、各走行ポンプには、各操作弁から供給される作動油が流れる第２油路３２が各操作弁に接続され、各走行モータには、該走行モータの回転数を計測する第３測定装置６３がそれぞれ取り付けられる。制御装置は、設定部材からの設定信号及び各第３測定装置からの回転数信号に基づいて、各操作弁から供給される作動油の圧力を調整するように、各操作弁の手動による操作から独立して各操作弁を作動させ、各操作弁は、各走行ポンプから吐出される作動油の流量を調整する。【選択図】図４
