Abstract
(EN)
 A control device (40) of a wheel loader calculates a first ratio, which is the ratio of a value corresponding to the target travel distance that serves as the target when the wheel loader travels to a position at which excavated objects are discharged after excavation by the bucket, and a value corresponding to the target elevation amount that serves as the target when the boom is raised after the start of movement. The control device (40) also calculates the difference between the first ratio and a second ratio, which is the ratio of a value corresponding to the actual distance the wheel loader travels after the start of movement to the position at which excavated objects are discharged after excavation by the bucket, and a value corresponding to the actual amount the boom is raised after the start of movement. The control device (40) then controls the transmission torque that is transmitted from the engine to the drive wheels such that the difference between the first ratio and the second ratio is zero.

L'invention concerne un dispositif de commande (40) de chargeuse montée sur roues, qui calcule un premier rapport qui est le rapport entre une valeur correspondant à la distance de déplacement cible servant de distance cible lorsque la chargeuse montée sur roues se déplace vers une position où les objets excavés sont déchargés après excavation par un godet, et une valeur correspondant à la quantité d'élévation de cible qui sert de cible lorsque la flèche est levée après le début du déplacement. Le dispositif de commande (40) calcule également la différence entre le premier et un second rapport, qui est le rapport entre une valeur correspondant à la distance réelle que la chargeuse montée sur roues parcourt après le début du déplacement vers la position où les objets excavés sont déchargés après excavation par le godet, et une valeur correspondant à la quantité réelle de levage de la flèche après le début du déplacement. Le dispositif de commande (40) commande ensuite le couple de transmission qui est transmis du moteur aux roues d'entraînement, de telle sorte que la différence entre le premier rapport et le second rapport est nulle.

 ホイールローダーの制御装置40は、ホイールローダーがバケットによる掘削後に掘削物を排出する位置まで走行する際の目標となる目標走行距離に対応する値と、移動が開始された後にブームが上昇する際の目標となる目標上昇量に対応する値との比である第1比率を求める。また、制御装置40は、ホイールローダーがバケットによる掘削後に掘削物を排出する位置までの移動を開始してから実際に走行した距離に対応する値と、移動が開始された後にブームが実際に上昇した量に対応する値との比である第2比率との差を求める。そして、制御装置40は、第1比率と第2比率との差が0になるように、エンジンから駆動輪に伝達される伝達トルクを制御する。
