Abstract:
(EN) A mobile working machine, in particular an agricultural device such as a self-propelled sprayer, comprising a structure which is hydraulically supported with respect to an undercarriage by means of cylinders (2, 4) having a piston chamber (6) and a rod chamber (8), wherein a switching device (18, 22, 36, 38) is provided which, in a switching position, fluidically connects the piston chamber (6) of a cylinder (2, 4) to the rod chamber (8) of another cylinder (2, 4), and vice versa, <b>characterised in that</b>, as part of the switching device, first valves (18, 22) and second valves (36, 38) are connected on the fluid-conveying connection (12, 14) between the piston chamber (6) of the one cylinder (2, 4) and the rod chamber (8) of the other cylinder (2, 4), the first valves (18, 22) each being connected on the input side to the piston chamber (6) and to a first hydraulic accumulator (28, 30) and the second valves (36, 38) being connected on the input side to the rod chamber (8) and on the output side to a second hydraulic accumulator (32, 34).
(FR) L'invention concerne un engin de travail mobile, en particulier un appareil agricole tel qu'un pulvérisateur automoteur, comprenant une carrosserie qui est supportée hydrauliquement par rapport à un train roulant au moyen de cylindres (2, 4) comprenant une chambre de piston (6) et une chambre de tige (8), un dispositif de commutation (18, 22, 36, 38) étant prévu, lequel relie fluidiquement, dans une position de commutation, la chambre de piston (6) d'un cylindre (2, 4) à la chambre de tige (8) d'un autre cylindre (2, 4) et inversement, caractérisé en ce que des premières (18, 22) et deuxièmes soupapes (36, 38) sont respectivement raccordées à la liaison fluidique (12, 14) respective entre la chambre de piston (6) de l'un des cylindres (2, 4) et la chambre de tige (8) de l'autre cylindre (2, 4) en tant que partie du dispositif de commutation, soupapes parmi lesquelles les premières soupapes (18, 22) sont raccordées respectivement côté entrée à la chambre de piston (6) et à respectivement un premier accumulateur hydraulique (28, 30) et les deuxièmes soupapes (36, 38) sont raccordées respectivement côté entrée à la chambre de tige (8) et côté sortie à respectivement un deuxième accumulateur hydraulique (32, 34).
(DE) Eine fahrbare Arbeitsmaschine, insbesondere landtechnisches Gerät wie selbstfahrende Spritze, mit einem Aufbau, der gegenüber einem Fahrwerk mittels Kolbenraum (6) und Stangenraum (8) aufweisenden Zylindern (2, 4) hydraulisch abgestützt ist, wobei eine Schalteinrichtung (18, 22, 36, 38) vorgesehen ist, die in einer Schaltstellung den Kolbenraum (6) eines Zylinders (2, 4) mit dem Stangenraum (8) eines anderen Zylinders (2, 4) und umgekehrt fluidführend verbindet, dadurch gekennzeichnet, dass an der jeweiligen fluidführenden Verbindung (12, 14) zwischen Kolbenraum (6) des einen Zylinders (2, 4) und dem Stangenraum (8) des anderen Zylinders (2, 4) als Teil der Schalteinrichtung jeweils erste (18, 22) und zweite Ventile (36, 38) angeschlossen sind, von denen die jeweils ersten (18, 22) eingangsseitig an den Kolbenraum (6) und an jeweils einen ersten Hydrospeicher (28, 30) angeschlossen sind und die jeweils zweiten Ventile (36, 38) eingangsseitig an den Stangenraum (8) und ausgangsseitig an jeweils einen zweiten Hydrospeicher (32, 34) angeschlossen sind.
