Claims (2)
- 舗装機械の左右の駆動輪を回転させる複数の油圧モータに圧油を吐出する1つの油圧ポンプに対して、舗装機械の目標走行速度に応じた電流値の圧油吐出指令信号を出力する圧油吐出指令手段を備える舗装機械の走行駆動制御装置において、
前記圧油吐出指令手段は、前記各駆動輪の回転による舗装機械の走行開始に際して、前記圧油吐出指令信号の電流値を、目標走行速度よりも速い速度に応じた変化であって、混合物を積んでいない空荷状態で走行開始する時に前記各駆動輪を均等に駆動させる変化量で増加させてから所定時間経過後に目標走行速度に応じた電流値とすることを特徴とする舗装機械の走行駆動制御装置。 - 前記舗装機械は、前記油圧ポンプの駆動軸の軸線に対する斜板の傾斜角度をシリンダの伸縮によって変更して前記油圧ポンプによる圧油吐出量を調整する傾斜角変更装置と、前記シリンダに供給される圧油量を調整して前記シリンダの伸縮を制御するレギュレータとを備え、
前記圧油吐出指令手段は、前記レギュレータに対して前記圧油吐出指令信号を出力することを特徴とする請求項1に記載の舗装機械の走行駆動制御装置。
