Title (EN) ELECTRO HYDRAULIC DRIVE AND CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE ET D'ENTRAÎNEMENT ÉLECTROHYDRAULIQUE
Abstract:
(EN) A operator supporting electrohydraulic drive and control system based on, position sensors (8) (9), a electronic control unite ECU (2), a recovery, storing and re-use system for energy, and with actuator (3) (4) and the drive control valve (6) (7) bolted together in one (3+6) (4+7) unite and with the valve (6) (7) independently of the ECU (2) is controlling effective use of pump capacity and recovery of energy and with control of speed for low speeds, or prevented speed by valves (6) (7) or pump (10) (10a) (11) (11a) displacement and for higher speed with control of deplacement of pumps and motors and with valves (6) (7) at the same time controlled to be fully open.
(FR) L'invention concerne un système de commande et d'entraînement électrohydraulique d’aide à l’opérateur, basé sur des capteurs de position (8) (9), une unité de commande électronique (ECU) (2), un système de récupération, de stockage et de réutilisation d'énergie, ainsi qu'un actionneur (3) (4) et une vanne de commande d'entraînement (6) (7) boulonnées ensemble pour former une même unité (3+6) (4+7) ; la vanne (6) (7), indépendamment de l'ECU (2), commande l'utilisation efficace de la capacité de pompe et la récupération d'énergie et réalise une commande de vitesse pour des vitesses faibles, ou une vitesse empêchée par le déplacement des vannes (6) (7) ou de la pompe (10) (10a) (11) (11a), et pour une vitesse plus élevée avec la commande du déplacement de pompes et de moteurs avec les vannes (6) (7) commandées en même temps pour être complètement ouvertes.
