摘要： A servo-steering valve for a hydraulic servo-steering arrangement includes an input shaft, an output shaft and a valve. The valve comprises first and second valve members. The first and second valve members are rotatable relative to each other upon rotation of the input shaft relative to the output shaft. One of the valve members is rotatably arranged. The servo-steering valve further comprises a restoring element. The rotatable valve member is biased by the restoring element so as to assume a non-rotated initial position.

摘要： A valve device (10) for a hydraulic servo-steering arrangement includes two valve elements (18, 14) which can be rotated from a neutral position relative to each other, in order to thereby achieve the superimposition of an additional steering moment. The valve device (10) further includes a linear actuator (33) and a gear (20) coupling the two valve elements (18, 14) to each other. The gear (20) converts a linear stroke of the linear actuator (30) into a rotation. The gear (20) includes a first cogwheel (22) with teeth inclined in a first direction in relation to the axial direction of the cogwheel. The first cogwheel (20) is coupled to the first valve element (18). The gear (20) further includes a second cogwheel (30) with teeth inclined in a second direction opposed to the first direction. The second cogwheel (30) is axially displaceable by the linear actuator (33).

摘要： A method to actively trigger a servo valve of a hydraulic power steering system is disclosed herein. In the method, a present steering wheel torque is ascertained by a sensor. The method also includes the step of a desired rack-and-pinion force offset is specified. The method also includes the step of a desired steering wheel torque offset is specified. The method also includes the step of a desired shape of a power steering characteristic curve is specified. On the basis of the specified offset values, the ascertained steering wheel torque and the specified shape of the power steering characteristic curve, a setpoint is ascertained for a differential pressure at a hydraulic cylinder of the power steering system. Based on the steering wheel torque and on the setpoint for the differential pressure at the hydraulic cylinder, a setpoint is ascertained for a setting angle (φ) of a valve component. The method also includes the step of rotating an appropriate valve component of the servo valve until the setpoint of the setting angle of the valve component is reached.
