摘要： A hydraulic steering system (1) includes a steering command device (2) having a steering sensor (3), a steering motor (6), a wheel sensor (9), a pressure source (P), and control means (12) controlling a fluid supply from the pressure source (P) to the steering motor (6), wherein the control means (12) has an open loop control (19). Such a steering system should have a good relationship between steering input from the operator and steering behaviour of the vehicle to be steered. To this end the control means (12) include in addition to the open loop control (19) a closed loop control (20), wherein cross-over transition means (21) are provided which are connected to the open loop control (19) and to the closed loop control (20) and control a transition between the open loop control (19) and the closed loop control (20).

摘要： A fluid controller includes a first fluid meter defining a first plurality of volume chambers and a second fluid meter defining a second plurality of volume chambers. A selector assembly, disposed between the first fluid meter and the second fluid meter, includes a selector plate defining a bore and a selector valve disposed in the bore. The selector valve is adapted for rotational movement between a first position and a second position and includes a first face and an oppositely disposed second face. The selector valve defines a plurality of thru-passages that extend axially through the first and second faces and that is adapted to provide fluid communication between the first and second volume chambers in the first position. The selector valve defines a groove disposed on the second face. The groove recirculates fluid from the second plurality of volume chambers when the selector valve is in the second position.

摘要： A vehicle including a steering system for moving a pair of wheels supported by a wheel support structure relative to a vehicle structure to achieve steering of the vehicle whilst the vehicle is travelling. The system including a pressure source for providing a supply of pressurized fluid through first and second steering valves to fluid operated first and second actuators, each of which includes an actuating member. The steering valves are operator controlled to provide the pressurized fluid, at least when the steering system is in a first operating mode, from both the first steering valve to the first actuator and from the second steering valve to the second actuator to achieve steering. When the steering system is operating in a second operating mode, only one of the first and second steering valves provides pressurized fluid from the source to a respective one of the actuators to achieve steering.
