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 Steering motors (4a, 4b) connected to said steering devices (3a, 3b), each of which includes a high-pressure port (Pa, Pb) and a low-pressure port (Ta, Tb) ), a working port arrangement with two working ports (La, Ra; Lb, Rb) connected to said steering motors (4a, 4b), control valves (5a, 5b) and measuring motors (6a, 6b). The steering system should have comfortable steering characteristics. To this end, in each of said steering devices (3a, 3b), said measuring motor (6a, 6b) is arranged between one of said working ports (La, Ra; Lb, Rb) and said In the working lines (19a, 20b) between the control valves (5a, 5b).

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...
