Title (EN) POWER REGENERATION SYSTEM FOR WORK VEHICLES

(JA) 作業車両の電力回生システム
Abstract:
(EN) The present invention makes effective use of regenerative electrical power without providing a high-voltage DC line with a power storage device such as a battery. A power regeneration system for work vehicles comprises: a first generator (12) and a second generator (31) which are driven by the engine (11); a first electrical circuit (C1) for supplying electrical power to traveling motors (10L, R); a second electrical circuit (C2) for supplying electrical power to an auxiliary machine (35); a step-down device (21) which supplies electrical power from the first electrical circuit to the second electrical circuit; and a controller (51) which determines whether the travel mode of a work vehicle is the powering mode or the regenerative mode and controls the drive of the step-down device. In the regenerative mode, the controller supplies regenerative electrical power from the first electrical circuit to the second electrical circuit via the step-down device, and drives the auxiliary machine with the regenerative electrical power.
(FR) La présente invention permet une utilisation efficace de l'énergie électrique régénérative sans fournir de ligne CC à haute tension avec un dispositif d'emmagasinage d'énergie tel qu'une batterie. Un système de régénération de puissance pour véhicules de travail comprend : un premier générateur (12) et un second générateur (31) qui sont entraînés par le moteur (11) ; un premier circuit électrique (C1) pour apporter de l'énergie électrique à des moteurs de déplacement (10L, R) ; un second circuit électrique (C2) pour apporter de l'énergie électrique à une machine auxiliaire (35) ; un dispositif abaisseur (21) qui apporte de l'énergie électrique du premier circuit électrique au second circuit électrique ; et un dispositif de commande (51) qui détermine si le mode de déplacement d'un véhicule de travail est le mode alimentation ou le mode régénératif et commande l'entraînement du dispositif abaisseur. Dans le mode régénératif, le dispositif de commande apporte de l'énergie électrique régénérative du premier circuit électrique au second circuit électrique par l'intermédiaire du dispositif abaisseur, et commande la machine auxiliaire avec la puissance électrique régénérative.
