WORK MACHINE, WORK MACHINE CONTROLLER, AND WORK MACHINE CONTROL METHOD
To reduce shock occurring when switching from whole wheel driving to rear wheel driving.SOLUTION: A work machine has front wheels, a front wheel driving device to drive the front wheels to rotate, rear wheels, a rear wheel driving device to drive the rear wheels to rotate, a clutch that selectively couples the front wheels and the front feel driving device, and a controller to control the front wheel driving device and the clutch. When receiving input of command to maintain rotation driving of the rear wheels by the rear wheel driving device and stop rotation driving of the front wheels by the front wheel driving device, the controller starts reducing a rotation driving force transmitted from the front wheel driving device to the front wheels. When determining that the rotation driving force becomes smaller than a determination value, or that a prescribed time passed after starting reducing the rotation driving force, the controller releases the clutch.SELECTED DRAWING: Figure 5
【課題】全輪駆動から後輪駆動に切り替える際のショックを低減する。【解決手段】作業機械は、前輪と、前輪を回転駆動させる前輪駆動装置と、後輪と、後輪を回転駆動させる後輪駆動装置と、前輪と前輪駆動装置とを選択的に連結するクラッチと、前輪駆動装置およびクラッチを制御するコントローラとを備えている。コントローラは、後輪駆動装置による後輪の回転駆動を維持し前輪駆動装置による前輪の回転駆動を停止させる指令の入力を受けると、前輪駆動装置から前輪に伝達される回転駆動力の減少を開始する。コントローラは、回転駆動力が判定値よりも小さくなったと判断されるか、または、回転駆動力の減少を開始してから一定時間が経過したと判断されると、クラッチを解放する。【選択図】図５
