    • The invention relates to a hydraulic steering system (1) with a hydraulic steering unit (2), a priority valve (4), a pump (3), which is connected with the steering unit (2) via a supply line (16), in which the priority valve is arranged (4), and with a load-sensing system and at least one additional pressure sink (5), which is connected with the priority valve (4). In this connection it is endeavoured to ensure the steering, also when the pressure sink has a consumption of load-sensing pressure. For this purpose, the load-sensing system has a first load-sensing line (9), with a pressure (LS) determined by the steering unit, which pressure determines the position of the priority valve (4), and a second load-sensing line (13), which is connected on the one side with the control input (6) of the pump (3) and the additional pressure sink (5) and on the other side with a point in the supply line (16), means being provided for the adaptation of the pressure in the second load-sensing line (13) to the pressure in the first load-sensing line (9).
    • 本发明涉及一种具有液压转向单元(2),优先阀(4),泵(3)的液压转向系统(1),其经由供应管线(16)与转向单元(2)连接, ,其中配置有优先阀(4),并具有与优先阀(4)连接的负载感测系统和至少一个附加压力槽(5)。 在这方面,也努力确保转向,当压力传感器消耗负载感测压力时也是如此。 为此,负载感测系统具有第一负载感测线(9),其中压力(LS)由转向单元确定,该压力决定优先阀(4)的位置, 感测线路(13),其一侧与泵(3)的控制输入端(6)和附加压力传感器(5)连接,另一侧与供电线路(16)中的点连接, 提供用于将第二负载感测线路(13)中的压力适应于第一负载感测线路(9)中的压力的​​装置。

    • This invention relates to a fully hydraulic steering (1) with a steering unit (2) having a supply connection arrangement (P, T) and a working connection arrangement with two working connections (L, R), a first steering motor (3), which acts upon at least one first wheel, a second steering motor (5), which acts upon at least one second wheel, both steering motors (3, 5) being connected in series with the steering unit (2) in at least one operation mode. It is endeavoured to improve the steering behaviour. For this purpose, a compensation valve arrangement (17, 17’, 17’’) is provided, with which the inlet or outlet of a fluid amount between the two steering motors (3, 5) can be controlled.
    • 本发明涉及一种具有转向单元(2)的全液压转向装置(1),该转向装置具有供给连接装置(P,T)和具有两个工作连接(L,R)的工作连接装置,第一转向马达(3) ,其作用在至少一个第一轮上,第二转向马达(5),其作用在至少一个第二轮上,两个转向马达(3,5)在至少一个与所述转向单元(2)串联连接 操作模式。 努力改善转向行为。 为此,设置补偿阀装置(17,17',17“),可以控制两个转向马达(3,5)之间的流体量的入口或出口。
