Abstract[English]
A hydraulic drive includes a hydraulic circuit having a hydraulic machine, a hydraulic consumer, a first hydraulic line, and a second hydraulic line. The hydraulic drive further includes an inertia charging arrangement having a hydraulic motor configured, in response to a power failure of the hydraulic drive, to receive hydraulic fluid from a high-pressure line of the first and second hydraulic lines and to expel hydraulic fluid to a low-pressure line of the first and second hydraulic lines, and a hydraulic pump operably connected to the hydraulic motor such that the hydraulic motor drives the hydraulic pump. The hydraulic pump is configured to pump hydraulic fluid from a reservoir into the low-pressure line.[French]
L'invention concerne un entraînement hydraulique comportant un circuit hydraulique équipé d'une machine hydraulique, d'un consommateur hydraulique, d'une première conduite hydraulique et d'une seconde conduite hydraulique. L'entraînement hydraulique comporte en outre un dispositif de charge par inertie équipé d'un moteur hydraulique conçu pour, en cas de panne d'alimentation de l'entraînement hydraulique, recevoir un fluide hydraulique provenant d'une conduite haute pression parmi les première et seconde conduites hydrauliques et pour refouler ce fluide hydraulique vers une conduite basse pression parmi les première et seconde conduites hydrauliques, et d'une pompe hydraulique reliée fonctionnellement au moteur hydraulique de sorte que le moteur hydraulique entraîne la pompe hydraulique. La pompe hydraulique est conçue pour acheminer le fluide hydraulique depuis un réservoir vers la conduite basse pression.
