Title (EN) WORK VEHICLE
(FR) ENGIN DE CHANTIER
(JA) 作業車両
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 vehicle is a work vehicle comprising a variable-capacity supercharger in which the boost pressure is changeable, and a work device that is driven by pressure oil discharged from a working hydraulic pump. The work vehicle comprises: 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 rotation speed of an engine and/or the maximum vehicle speed of the work vehicle when the temperature of the supercharger control device is higher than a predetermined temperature compared to when the temperature is lower than the predetermined 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 qui est entraîné par une huile sous pression refoulée par une pompe hydraulique de travail. L'engin de chantier comprend : 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 la vitesse de rotation maximale d'un moteur et/ou la vitesse maximale de l'engin de chantier lorsque la température du dispositif de commande de compresseur de suralimentation est supérieure à une température prédéterminée par comparaison à la situation dans laquelle la température est inférieure à la température prédéterminée.
(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、作業車両は、過給圧を変更可能な可変容量式の過給機と、作業用油圧ポンプから吐出される圧油によって駆動される作業装置と、を備えた作業車両であって、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所定温度よりも高いときには、前記所定温度よりも低いときに比べて、エンジンの最高回転速度および前記作業車両の最高車速のうちの少なくとも1つを制限する主制御装置と、を備えている。
