Embodiment Construction

[0021] The hydraulic steering system 1 includes a first steering circuit 2a and a second steering circuit 2b. The first steering circuit 2a comprises a first steering device 3a and a first steering motor 4a connected to the first steering device 3a. The first steering device 3a comprises a supply port arrangement with a high pressure port Pa and a low pressure port Ta, a working port arrangement with a first working port La and a second working port Ra, where both working ports La, Ra are connected to the steering motor 4a. The first steering device 3a also includes a control valve 5a and a measuring motor 6a. Finally, the first steering circuit 2a comprises a supply pump 7a connected to the high pressure port Pa and a tank 8a connected to the low pressure port Ta.

[0022] In a similar manner, the second steering circuit 2b comprises a second steering device 3b and a second steering motor 4b. The second steering device 3b comprises a second control valve 5b and a second mea...

Abstract

A hydraulic steering system (1) is described comprising a first steering circuit (2a) and a second steering circuit (2b), each of said steering circuits (2a, 2b) comprising a steering device (3a, 3b) and a steering motor (4a, 4b) connected to said steering device (3a, 3b), each of said steering devices (3a, 3b) comprising a supply port arrangement having a high pressure port (Pa, Pb) and a low pressure port (Ta, Tb), a working port arrangement having two working ports (La, Ra; Lb, Rb) connected to said steering motor (4a, 4b), a control valve (5a, 5b), and a measuring motor (6a, 6b). Such a steering system should have a comfortable steering behavior. To this end in each of said steering devices (3a, 3b) said measuring motor (6a, 6b) is arranged in a working line (19a, 20b) between said control valve (5a, 5b) and one of said working ports (La, Ra; Lb, Rb).

Description

technical field [0001] The present invention relates to a hydraulic steering system comprising a first steering circuit and a second steering circuit, each of said steering circuits comprising a steering device and a steering motor connected to said steering device, each of said steering devices being A supply port arrangement having a high pressure port and a low pressure port, a work port arrangement having two work ports connected to the steering motor, a control valve and a gauge motor are included. Background technique [0002] Such a steering system is known for example from EP2186710A1. [0003] The use of two steering circuits has the advantage of greater reliability. The risk of dangerous states during operation of a vehicle equipped with the steering system is reduced. When a vehicle equipped with this steering system is driven, the driver actuates a steering member connected to the control valve, for example a steering wheel. Depending on the direction of steer...
