摘要： A method of controlling a power steering system having an adjusting mechanism for adjusting at least one vehicle wheel is disclosed herein. The system includes a steering wheel, a position sensor, and a drive system, such as a servo pump driven by an electric motor, to provide steering assistance a steering wheel and a position sensor. It is determined whether the adjusting mechanism is approaching an end position. If it is found that the adjusting mechanism is approaching the end position, then the drive system is controlled in such a way that it provides a diminishing steering assistance.

摘要： The invention concerns a method of manufacturing a joint housing, in particular for vehicle track rods, having an integral shaft with an internal thread designed to hold a longitudinal pin, the housing being produced from a blank with a ball-like enlargement at one end. In order to ensure low manufacturing costs and low consumption of energy and materials, a longitudinal cavity with a diameter exceeding that of the internal thread and a length exceeding that of the threaded section is first produced in the shaft of the blank by rearwards cup extrusion and the diameter of the threaded section subsequently reduced to that of the thread core while at the same time shaping the surface of the wall to give a flat key face, the overall process being a cold-forming one. Finally, both the external and internal features of the housing are produced by heading, cupping, punching and forming to size perpendicular to the longitudinal axis in the region of the enlargement.

摘要： The invention concerns a steering valve with a closed center for supplying an actuator with hydraulic pressure, the steering valve comprising an input shaft, and output shaft, a torsionally resilient element which is connected at one end to the input shaft and at the other end to the output shaft, a control pressure switching arrangement and a torque/axial force conversion unit. A spring loaded seat valve is located in a bore of the input shaft, and closes a fluid passage passing through the torsion tube. The torque/axial force convertor opens the seat valve when relative twisting of the input shaft with respect to the valve casing occurs. According to the invention, in order to improve the response dynamics of such a steering valve, the valve comprises at least one axial bore for supplying hydraulic pressure. At one end this bore is closed by a valve which is loaded by the torque/axial force conversion unit against the hydraulic pressure.

摘要： The invention discloses a method for controlling the hydraulic pressure in a power steering device that serves for supplying compressed oil to the left and the right chamber of a power steering cylinder via a rotary slide valve with the aid of a pump, wherein a reaction piston arranged on the input shaft in axially movable and rotationally rigid fashion and connected to the control sleeve of the rotary slide valve via an elastic rotary coupling is inserted between the input shaft and the control sleeve of the rotary slide valve, and wherein a hydraulic reaction device controlled by a control unit with dependence on speed and which serves to control the reaction pressure is arranged in a return line for the hydraulic medium which leads away from the reaction piston. According to the invention, the changes in the hydraulic pressure are determined and used as control parameters for the hydraulic reaction device that is controlled with dependence on speed in addition to the parameter speed.
