Claims (3)
- 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と、これら各油圧モータに圧油を供給して前記各油圧モータを駆動する1つの油圧ポンプと、前記各油圧モータから前記各駆動輪に伝達される回転の回転速度を減速する減速機と、舗装機械の走行条件を舗装施工時の条件または移動走行時の条件のいずれかに選択する走行条件選択手段とを備える舗装機械の走行駆動装置において、
前記走行条件選択手段による選択に応じて、前記減速機による減速比および前記各油圧モータに吸収される大または小の圧油吸収量の予め決まっている複数の組合せの中からいずれかの組合せを選択し、前記走行条件選択手段により舗装施工時の条件が選択されて前記各駆動輪の回転による舗装機械の走行開始時であると判別すると、前記圧油吸収量が小の前記組合せを選択し、前記圧油吸収量を一定値以下に保つ制御装置を備えることを特徴とする舗装機械の走行駆動装置。 - 前記走行条件選択手段は、前記減速比を高速または低速のいずれかに切り換える減速機切換スイッチと、前記圧油吸収量を大または小のいずれかに切り換える圧油吸収量切換スイッチとを備え、
前記制御装置は、前記減速機切換スイッチが低速の減速比に切り換えられて舗装施工時の条件が選択されていると判別すると、前記圧油吸収量切換スイッチが大の圧油吸収量に選択されても、前記圧油吸収量を小に切り換えた状態で固定し、前記圧油吸収量が小の前記組合せを選択するマイコンから構成され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装置。 - 前記走行条件選択手段は、前記減速比を高速または低速のいずれかに切り換える減速機切換スイッチと、この減速機切換スイッチが高速に切り換えられると電源供給を受けて前記圧油吸収量を大または小のいずれかに切り換える圧油吸収量切換スイッチとを備え、
前記請求項1に記載の制御装置は、前記減速機切換スイッチが低速に切り換えられると電源供給を受けて前記減速比を低速に切り換える減速機低速側切換ソレノイドと、前記減速機切換スイッチが低速に切り換えられるか、前記減速機切換スイッチが高速に切り換えられて前記圧油吸収量切換スイッチが小側に切り換えられると電源供給を受けて前記圧油吸収量を小に切り換える圧油吸収量小側切換ソレノイドと、前記減速機切換スイッチが高速に切り換えられると電源供給を受けて前記減速比を高速に切り換える減速機高速側切換ソレノイドと、前記減速機切換スイッチが高速に切り換えられて前記圧油吸収量切換スイッチが大側に切り換えられると電源供給を受けて前記圧油吸収量を大に切り換える圧油吸収量大側切換ソレノイドとから構成される電気回路により形成され、前記減速機切換スイッチが低速の減速比に切り換えられて舗装施工時の条件が選択されていると、前記圧油吸収量切換スイッチが大または小のいずれの圧油吸収量に選択されても、前記圧油吸収量小側切換ソレノイドが電源供給を受けて前記圧油吸収量を小に切り換え、前記圧油吸収量が小の前記組合せを選択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装置。
