Embodiment Construction

[0021] figure 1 A hydraulic steering arrangement 1 is shown schematically, comprising: a supply port arrangement with two supply ports 2, 3; a return port arrangement with two return ports 4, 5; and a work port arrangement, It has two working ports 6,7.

[0022] Furthermore, the steering arrangement 1 comprises a first valve arrangement 8 and a second valve arrangement 9 . The first valve arrangement 8 includes a first supply side 10 connected to the first supply port 2 and the first return port 4 . Furthermore, the first valve arrangement 8 comprises a first output side 11 connected to the working ports 6 , 7 . Similarly, the second valve arrangement 9 comprises a second supply side 12 connected to the second supply port 3 and the second return port 5 and a second output side 13 connected to the working ports 6 , 7 .

[0023] The two work ports 6, 7 are connected to a hydraulic actuator 14, such as a steering motor. The actuator 14 acts on steered wheels (not shown). For...

Abstract

A hydraulic steering arrangement (1) is described herein comprising: a supply port arrangement with at least one supply port (2, 3); a return port arrangement with at least one return port (4, 5); A working port arrangement of two working ports (6, 7); a first valve arrangement (8) having a first supply side (10) connected to the supply port arrangement and a first output side (11) connected to the working port arrangement a second valve arrangement (9) having a second supply side (12) connected to the supply port arrangement and a second output side (13) connected to the work port arrangement; and a steering command device (19). The object of the invention is to improve the steering behaviour. For this, at a neutral steering angle, the second valve arrangement (9) connects the first output side (11) to the return port arrangement and the first valve arrangement (8) connects the second output side (13) to the return port arrangement .

Description

technical field [0001] The present invention relates to a hydraulic steering arrangement comprising: a supply port arrangement with at least one supply port; a return port arrangement with at least one return port; a work port arrangement with two work ports; a first valve arrangement, It has a first supply side connected to the supply port arrangement and a first output side connected to the work port arrangement; a second valve arrangement with a second supply side connected to the supply port arrangement and a second supply side connected to the work port arrangement the output side; and the steering command device. Background technique [0002] The driver uses the steering command device to determine the direction in which a vehicle equipped with this steering arrangement should be steered. The steering command device may be, for example, a steering wheel or a joystick. The steering command device may also be a component of a remote control or GPS steering to automatic...
