DRIVING DEVICE FOR WORK MACHINE
PROBLEM TO BE SOLVED: To provide a driving device for a work machine, for enabling the discharge flow rate of a pump according to the control input of a control lever to be accurately distributed to hydraulic actuators to be supplied.SOLUTION: In a driving device for a work machine according to this invention, a controller 26 is provided which includes a switching area setting part 90 for setting a plurality of switching areas 100 for a solenoid switching valve 24 in combinations of the numbers of closed circuit pumps 21a-21f which are used by a plurality of hydraulic actuators including a boom cylinder 13a and an arm cylinder 13b, and a true command switching valve arithmetic circuit 91 for computing an on/off command value for the solenoid switching valve 24 again from the switching areas 100 set by the switching area setting part 90, an on/off command valve for the solenoid switching valve 24 computed by a command switching valve arithmetic circuit 32 and a required flow rate computed by a required flow rate arithmetic circuit 30 to update the on/off command value.
【課題】操作レバーの操作量に応じたポンプの吐出流量を油圧アクチュエータに精度良く配分して供給することができる作業機械の駆動装置の提供。【解決手段】本発明に係る作業機械の駆動装置は、コントローラ２６が、ブームシリンダ１３ａ及びアームシリンダ１３ｂ等複数の油圧アクチュエータが使用している閉回路ポンプ２１ａ〜２１ｆの数の組合せごとに電磁切換弁２４に対する複数の切換領域１００を設定する切換領域設定部９０と、切換領域設定部９０で設定した切換領域１００と指令切換弁演算回路３２で演算された電磁切換弁２４のオンオフ指令値及び要求流量演算回路３０で演算された要求流量から電磁切換弁２４のオンオフ指令値を再度演算し、オンオフ指令値を更新する本指令切換弁演算回路９１とを備えた構成にしてある。【選択図】図９
