摘要： An aspect of the present disclosure relates to a steering system having first and second steering circuits in fluid communication with a fluid actuator wherein the steering circuits are disposed in parallel to each other. The second steering circuit includes a proportional valve having a load-sense feature in selective fluid communication with a load-sense connection and the first steering circuit. The load-sense feature is open to the first steering circuit when the proportional valve is in a neutral position and closed to the first steering circuit when the proportional valve is moved to a first or second steering position. When the proportional valve is actuated from the neutral position to the first or second steering position the movement of the proportional valve closes the load sense feature from the first steering circuit and operates to deactivate the first steering circuit.

摘要： A steerable, self-propelled vehicle (20) includes a rotatable steering column that is connected to control the steering angle of one or more ground-engaging members of the vehicle. The vehicle includes between the steering column and the ground-engaging member a first steering servomechanism having at least a first steering assistance characteristic; a second steering servomechanism having a second steering assistance characteristic also being connected to act on the steering column. A controller is provided for causing the first and second steering assistance characteristics to influence the steering of the vehicle in dependence on one or more one or more control commands generated in the controller.

摘要： The invention relates to a control system (300) for a working machine (101), comprising a device (301) for changing direction of the working machine, an operator controlled lever (307), and an electronic control unit (351) adapted to receive an input signal indicative of desired direction from the position of the operator controlled element and to generate an output signal for producing a change of direction of the working machine, corresponding to the position of the operator controlled element, via said device (301). The control system (300) comprises an electronic safety device (353) adapted to be controlled by the position of the operator controlled element (307) and adapted to allow control of the device (301) via said output signal and to block control of the device (301) via said output signal, respectively, depending on the position of the operator controlled element.

摘要： The invention relates to a hydraulic steering system for a vehicle, especially for a mobile working machine. The inventive steering system has a steering unit (12) which is controlled by a first steering mechanism (11), said first steering mechanism being configured in the form of a steering wheel (11), and which has a first fluid connection (29) and a second fluid connection (30). The first fluid connection is connected to a steering motor (14, 14') pressure chamber (35, 36') which is subjected to pressure for a steer angle to the left. The second fluid connection is connected to a steering motor (14, 14') pressure chamber (36, 35') which is subjected to pressure for a steer angle to the right. The steering system also has a control valve (13) which is controlled by a second steering mechanism (55). Said second steering mechanism is configured in the form of a joystick (55) and also has fluid connections (143, 144) connected to the pressure chambers (35, 36', 36, 35') of the steering motor (14, 14'). The invention aims to provide a simple means of ensuring that a steering action with the first steering mechanism (11) takes priority over a steering action with the second steering mechanism (33). To this end, the control valve (13) can only be actuated when the steering unit (12) is in the neutral position.

摘要： A system for controlling the flow of fluid to a fluid pressure operated device (C) is disclosed. The system includes a controller of the type comprising first and second valve means (35, 37) for defining a first fluid path (MFP) and a second fluid path (AFP) in response to movement of a first input means (W) and a second input means (J), respectively. The second input means includes an electromagnetic actuator (65) to actuate the second valve means in response to an electrical input signal (CS). The system includes sensing means (S, PS, G, P), which can sense a predetermined condition and generate an interrupt signal in response thereto. Furthermore interrupt means are provided which interrupt the electrical input signal in response to the interrupt signal.
