Abstract: A pilot device for a hydraulic directional valve includes a displacement sensor, a pilot valve, an actuating device, a coil assembly, and a circuit board. The displacement sensor has a sensor axis and the pilot valve has a valve axis. The valve axis and the sensor axis are arranged substantially parallel to one another so as to lie in a reference plane. The actuating device and the coil assembly are arranged adjacent to one another. The circuit board is arranged parallel to the reference plane. In each case, to establish an electrical contact, the coil assembly, the actuating device, and an electrical plug connection are either soldered directly to the circuit board or are in breakable electrical contact with a respectively associated, rigid contact assembly. The contact assembly is soldered directly to the circuit board.

Abstract: A bearing for a ball screw drive may include a ball nut that is rotatable about a longitudinal axis and intended to receive a threaded spindle concentrically. The ball nut may be arranged in an inner ring and at least partially in an intermediate ring and an outer ring of the bearing. A belt pulley may be connected to the intermediate ring for rotation therewith, wherein an outer circumferential surface of the inner ring may be convex in some regions and an inner circumferential surface of the intermediate ring may be concave in some regions. The ball nut may be arranged in the bearing so as to be tiltable with respect to the belt pulley. The inner ring may be connected to the ball nut for rotation therewith and may be immovable in an axial direction. The intermediate ring may be connected via spring elements to the inner ring for rotation therewith.

Abstract: The invention relates to a ball screw (20) comprising a ball nut (21), a roller bearing (22) and a belt pulley (23) arranged on the roller bearing (22). The ball nut (21) is arranged in the roller bearing (22) such that there is no reduction in tension between that of the belt pulley (23) and an assisting engine arranged to the side of the ball screw (20).

Abstract: A bearing arrangement may involve two spring systems that are decoupled from one another. Some bearing arrangements may include components such as a bearing housing, a bearing, spring elements for supporting the bearing in the housing, and an abutment that can be moved in an axial direction of the bearing. Further, a method for assembling a bearing arrangement may involve a compensation mechanism having dimensions that can be subsequently adapted.

Abstract: The invention relates to an axially active wave spring having a closed annular body with a central x-axis, the annular body being undulated periodically over the circumference in the direction of the x-axis, in which the wave spring has a spring height in the direction of the x-axis, which spring height is different on the inner circumference of the wave spring than on the outer circumference of the wave spring.

Abstract: The invention relates to a servo-assisted steering system, in particular for a motor vehicle, having a servo motor which drives an axially displaceable component via a nut (1) which is mounted in a frame (9, 10) in a rotatable manner in a bearing (4), wherein the nut (1) engages with a threaded spindle (2) formed on the component and is supported via the bearing (4) elastically with respect to the frame (9, 10) in the axial direction by means of spring elements (18, 20) and is supported on the frame (9, 10) in the radial direction along a narrow encircling contact surface (8, 30), wherein the spring elements (18, 20) are corrugated springs.
