Abrégé
(DE)
Die Erfindung betrifft einen hydrostatischen Antrieb mit einem offenen hydraulischen Kreislauf (2) und einem geschlossenen hydraulischen Kreislauf (3). In dem offenen hydraulischen Kreislauf (2) ist zumindest ein hydraulischer Verbraucher (20, 21) einer Arbeitshydraulik: (18) angeordnet. Der geschlossene hydraulische Kreislauf (3) umfasst zumindest einen Arbeitskreislauf (37) und einen Fahrkreislauf (36), wobei in dem Arbeitskreislauf (37) zumindest ein weiterer hydraulischer Verbraucher (23) angeordnet ist.
(EN)
The invention relates to a hydrostatic drive with an open hydraulic circuit (2) and a closed hydraulic circuit (3). At least one hydraulic load (20, 21) of a working hydraulic system (18) is arranged in the open hydraulic circuit (2). The closed hydraulic circuit (3) comprises at least one working circuit (37) and one travel circuit (36), wherein at least one further hydraulic load (23) is arranged in the working circuit (37).
(FR)
L'invention concerne un mécanisme d'entraînement hydrostatique comprenant un circuit (2) hydraulique ouvert et un circuit (3) hydraulique fermé. Au moins une charge (20, 21) hydraulique d'un équipement (18) hydraulique de travail est disposée dans le circuit (2) hydraulique ouvert. Le circuit (3) hydraulique fermé comprend un circuit (37) de travail et un circuit (36) de déplacement, au moins une charge (23) hydraulique supplémentaire étant disposée dans le circuit (37) de travail.
