Abstract: For a hydraulic rack-and-pinion steering assembly for which a working piston is guided in a hydraulic cylinder which features an end limit stop by which, in an end position of the working piston, a path for the pressure agent supplied to the working piston by drill holes for the pressure agent is formed from the working space under pressure to a space of less pressure, in order to improve the hydraulic rack-and-pinion steering assembly such that it is simple to manufacture at limited cost, a rack-and-pinion steering assembly is improved by having, in the region of each pressure supply drill hole, at least one drill hole which can be executed and sealed from the housing exterior and which can be connected by means of a connecting line to the respective pressure supply.

Abstract: In order to additionally develop a conventional steering valve in such a way that it has a simple and economical design and is insensitive to pressure pulsations, a conventional steering valve is additionally developed by arranging at least one essentially coaxial chamber that extends in the shape of an arc and can be charged with hydraulic pressure either directly or indirectly on the input shaft or the output shaft, with at least one piston element that is directly or indirectly connected to the other shaft being arranged in the aforementioned chamber such that it can be moved along an essentially arc-shaped path.

Abstract: The invention concerns a device for securing a bearing shell (2) of a joint, particularly for suspension systems of motor vehicles, in a retaining opening (3a), particularly of a suspension rod or stabilizer. In order to reduce the processing efforts necessary for securing the bearing shell (2) and thus the manufacturing costs, the bearing shell (2) is formed with a conical cover surface (2a), which narrows in the direction of the coupling pin (1), on which a clamp collar (6) with a correspondingly conical opposing surface (6a) is arranged which is supported with its cylindrical cover surface (6b) in the retaining opening (3a).

Abstract: The invention pertains to a ball joint, having a ball joint socket (1), inside of which the ball (3c) of a ball-ended spindle (3) is arranged in a rotatable and tiltable manner by means of a bearing shell (2) that supports the ball (3c) below its largest diameter on a bearing surface that has the shape of a ball race, namely under the influence of spring force generated by a spring element (4) that simultaneously forms the upper bearing shell and is supported on the underside of a cover (5) that closes the ball joint socket (1). In order to entirely eliminate all manufacturing tolerances during assembly of the ball joint and provide defined spring forces that compensate for the wear-related elasticity of the ball joint until a defined wear is reached after assembly, the cover (5) which is realized in such a way that its outer diameter exceeds the inner diameter of the ball joint socket (1) in the initial state is nonpositively supported in the ball joint socket (1) with its edge (5c).
