Title (EN) ACCUMULATOR DEVICE AND HYDROPNEUMATIC SUSPENSION
(FR) DISPOSITIF ACCUMULATEUR ET SUSPENSION HYDROPNEUMATIQUE
(DE) SPEICHERVORRICHTUNG UND HYDROPNEUMATISCHE FEDERUNG
Abstract:
(EN) The invention relates to an accumulator device (10), consisting of at least two accumulator elements (14, 16) which are combined to form a structural unit (12) and have independently from one another their own accumulator characteristic curves (18, 20), in particular as a result of different preload pressures, wherein the respective accumulator characteristic curves (18, 20) provide a combined total accumulator characteristic curve (22), according to which a fluid can be stored in the structural unit (12) and can be retrieved therefrom. The invention further relates to a hydropneumatic suspension system (24) having such an accumulator device (10).
(FR) L'invention concerne un dispositif accumulateur (10) constitué d'au moins deux unités accumulateurs (14, 16) regroupées en une unité modulaire (12) et présentant, indépendamment l'une de l’autre, des courbes caractéristiques d'accumulation (18, 20) propres, notamment en raison des différences de pression de précontrainte, les courbes caractéristiques d’accumulation (18, 20) respectives une fois réunies formant une courbe caractéristique d'accumulation globale (22) selon laquelle un fluide peut être stocké dans l'unité modulaire (12) et prélevé de cette dernière. L'invention concerne en outre un système de suspension hydropneumatique (24) pourvu d’un tel dispositif accumulateur (10).
(DE) Die Erfindung betrifft eine Speichervorrichtung (10), bestehend aus mindestens zwei zu einer Baueinheit (12) zusammengefassten Speichereinrichtungen (14, 16), die unabhängig voneinander eigene Speicherkennlinien (18, 20), insbesondere aufgrund von unterschiedlichen Vorspanndrücken, aufweisen, wobei die jeweiligen Speicherkennlinien (18, 20) zusammengefasst eine Gesamt-Speicherkennlinie (22) ergeben, gemäß der ein Fluid in die Baueinheit (12) speicherbar und aus dieser abrufbar ist. Die Erfindung betrifft ferner ein hydropneumatisches Federungssystem (24) mit einer solchen Speichervorrichtung (10).
