  • Publication number: 20200317260
    Abstract: A hydraulic steering arrangement 1 is described comprising a supply port arrangement having at least a supply port (2, 3), a return port arrangement having at least a return port (4, 5), a working port arrangement having two working ports (6, 7), a first valve arrangement (8) having a first supply side (10) connected to the supply port arrangement (2, 3) and a first output side (11) connected to the working port arrangement (6, 7), a second valve arrangement (9) having a second supply side (12) connected to the supply port arrangement (2, 3) and a second output side (13) connected to the working port arrangement (6, 7), and a steering command device (19). It is an object of the present invention to improve the steering behaviour. To this end in a neutral steering angle the second valve arrangement (9) connects the first output side (11) to the return port arrangement (4, 5) and the first valve arrangement (8) connects the second output side (13) to the return port arrangement (4, 5).

  • Publication number: 20200114955
    Abstract: A hydraulic steering arrangement (1) comprising a supply port arrangement having a pressure port and a tank port, a working port arrangement having two working ports (L, R), a mechanical steering unit (3) connected to a steering wheel (2) and being arranged between the supply port arrangement and the working port arrangement (L, R), supply valve means (12) having a connection to the pressure port and to the working port arrangement (L, R) and being controlled by a controller (10), and a steering wheel sensor (9) connected to the controller (10) is described. Such a steering arrangement could allow a comfortable feeling for the driver.

  • Patent number: 10308280
    Abstract: Hydraulic steering (1) is disclosed comprising a high pressure port (P), a low pressure port (T), two working ports (CL, CR), a manual steering section (3), and a steering valve section having a steering valve 5 and a hydraulic driving arrangement (6) adjusting hydraulically a position of said steering valve. A change from automatic steering to manual steering should be reliably ensured when the manual steering section is directly influenced by a driver. To this end, a switching valve (11) is provided, which is actuatable between a first position in which said driving arrangement (6) is supplied with hydraulic fluid under pressure, and a second position in which a supply of hydraulic fluid to said driving arrangement (6) is interrupted, wherein said switching valve (11) is hydraulically actuated into said second position by a pressure generated upon actuating of said manual steering section (3).

  • Patent number: 9707998
    Abstract: A method for controlling steering of a vehicle (1) is provided, the vehicle (1) defining two or more steerable axes, and the vehicle (1) comprising a number of wheels (2), each of said wheels (2) being associated with one of said steerable axes in such a manner that steering of a given wheel (2) is obtained by steering the steerable axis associated therewith. The method comprises providing a first, a second and a third steering input. The first steering input defines a point of intersection between a virtual steering axis (4) and a longitudinal center axis defined by the vehicle (1). The second steering input defines an angle between the virtual steering axis (4) and the longitudinal center axis. The third steering input defines a position of a center of rotation (5) along the virtual steering axis (4).

  • Patent number: 9261084
    Abstract: A hydraulic control arrangement (1) is described having a directional valve (2), a metering pump unit which has at least two metering pumps (3, 4) which are connected hydraulically in parallel and are operable mechanically in parallel, and a shut-off valve (6) in hydraulic connection between two of the at least two metering pumps (3, 4), a pump connection (P) and a tank connection (T) which are connected to said metering pump unit by way of the directional valve (2), and two working connections (L, R) connected to the directional valve (2), a control input (8) of the shut-off valve (6) being connected to the pump connection (P) by means of a control valve. Such a control arrangement should be operated at a high hydraulic pressure and at the same time it should be made sure that the shut-off valve is actuated only when the required high pressure is available.
