(FR) ENGIN DE CHANTIER
(JA) 作業機械
Abstract:
(EN) The purpose of the invention is to suppress an increase in temperature of a control device for a supercharger and to increase the life of the control device for the supercharger. This work machine is a work machine comprising a variable-capacity supercharger in which the boost pressure is changeable, and a work device. The work machine comprises: a variable-capacity working hydraulic pump that is driven by an engine, and that supplies pressure oil to an actuator which drives the work device; a supercharger control device that controls the supercharger; a temperature detection device that detects the temperature of the supercharger control device; and a main control device that limits the maximum absorption torque of the working hydraulic pump when the temperature of the supercharger control device is higher than a first temperature compared to when the temperature is lower than the first temperature.
(FR) L'invention a pour but de supprimer une augmentation de température d'un dispositif de commande pour un compresseur de suralimentation et d'augmenter la durée de vie du dispositif de commande pour le compresseur de suralimentation. Cet engin de chantier est un engin de chantier comprenant un compresseur de suralimentation à capacité variable, dans lequel la pression de suralimentation est modifiable, et un dispositif de travail. L'engin de chantier comprend : une pompe hydraulique de travail de capacité variable qui est entraînée par un moteur et qui fournit de l'huile sous pression à un actionneur qui entraîne le dispositif de travail ; un dispositif de commande de compresseur de suralimentation qui commande le compresseur de suralimentation ; un dispositif de détection de température qui détecte la température du dispositif de commande de compresseur de suralimentation ; un dispositif de commande principal qui limite le couple d'absorption maximal de la pompe hydraulique lorsque la température du dispositif de commande de compresseur de suralimentation est supérieure à une première température par rapport à la situation dans laquelle la température est inférieure à la première température.
(JA) 過給機の制御装置の温度上昇を抑え、過給機の制御装置の寿命を向上するために、作業機械は、過給圧を変更可能な可変容量式の過給機と、作業装置を備えた作業機械であって、エンジンにより駆動され、前記作業装置を駆動させるアクチュエータに圧油を供給する可変容量型の作業用油圧ポンプと、前記過給機を制御する過給機制御装置と、前記過給機制御装置の温度を検出する温度検出装置と、前記過給機制御装置の温度が第1温度よりも高いときには、前記第1温度よりも低いときに比べて、前記作業用油圧ポンプの最大吸収トルクを制限する主制御装置と、を備えている。
