(JA) ハイブリッド型作業機械
Abstract: front page image
(EN)A hybrid working machine includes: an engine (11); a motor generator (12) connected to the engine (11); a variable displacement pump (14) rotationally driven by the output of the engine (11); and a control unit (30) controlling the variable displacement pump (14) and the number of rotations of the engine (11). The control unit (30) controls the number of rotations of the engine (11) on the basis of hydraulic load.
(FR)Cette invention concerne un engin de chantier hybride, comprenant : un moteur (11); un moteur-générateur (12) relié au moteur (11); une pompe volumétrique (14) entraînée en rotation par la puissance utile du moteur (11); et une unité de commande (30) qui commande la pompe volumétrique (14) et le nombre de rotations du moteur (11). L'unité de commande (30) commande le nombre de rotations du moteur (11) sur la base d'une charge hydraulique.
(JA) ハイブリッド型作業機械は、エンジンと(11)と、エンジン(11)に連結された電動発電機(12)と、エンジン(11)の出力により回転駆動される可変容量式油圧ポンプ(14)と、エンジン(11)の回転数及び可変容量式油圧ポンプ(14)を制御する制御部(30)とを含む。制御部(30)は、油圧負荷に基づいてエンジン(11)を回転数制御する。
