METHOD FOR CONTROLLING GEAR SHIFTING FOR GROUND CONSTRUCTION MACHINE AND GROUND CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a method for controlling gear shifting for a ground construction machine, which can set upper limit and lower limit values of a driving torque of a tool to perform automatic gear shifting between the two values stably and smoothly.SOLUTION: A method for controlling gear shifting for a ground construction machine, which has a tool 11, a hydraulic motor 81 capable of continuously changing a displacement volume, and a pressure detector 86 for detecting a pressure of fluid supplied to the hydraulic motor, comprises a step for setting an upper limit value and a lower limit value of a driving torque to be used, a step for setting a plurality of driving torque values within a range between the lower limit value and the upper limit value, a step for obtaining displacement volume values corresponding to a plurality of the set driving torque values, a step for setting a lower reference value or an upper reference value of the pressure, respectively, corresponding to a shift from the current displacement volume to a volume smaller by one level or to a volume larger by one level, a step for setting reference time for a shift from the current displacement volume to the adjacent volume on the smaller side and to the adjacent volume on the larger side, respectively, and a step for shifting to the volume smaller by one level or to the volume larger by one level by taking into account of the relationships between the pressure and the lower/upper reference values and duration thereof.
【課題】地盤施工機において、工具の駆動トルクの上限値と下限値を設定でき、その間で安定的かつ円滑な自動変速を行うことができる変速制御方法を提供する。【解決手段】工具１１と、押しのけ容積を連続的に変更可能な油圧モータ８１と、油圧モータへの供給流体の圧力検出器８６を備えた地盤施工機における変速制御方法であって、使用する駆動トルクの上限値と下限値を設定する手順と、下限値と上限値の範囲内で複数の駆動トルクを設定する手順と、設定した複数の駆動トルクに対応する押しのけ容積を求める手順と、現在の押しのけ容積から１段階小または大の容積への移行に対して圧力の下方基準値または上方基準値をそれぞれ設定する手順と、現在の押しのけ容積から隣接する容積への移行に対して基準時間をそれぞれ設定する手順と、圧力と下方基準値および上方基準値との関係とその継続時間を考慮して１段階小または大の容積に移行する手順を有する。【選択図】図２
