Abstract: A method for producing a threaded nut (10, 26) of a screw drive, in particular of a ball screw (7, 24), which threaded nut (10, 26) has, on one axial end, a recess (45) which extends over a circumferential segment and which is open at the end side, wherein said recess (45) is delimited radially by a circumferential wall of the threaded nut (10, 26), and wherein said recess (45) is delimited axially by a base (54) formed on the threaded nut (10, 26), and wherein said recess (45) is delimited in the circumferential direction by a stop surface (47), which is formed on the threaded nut (10, 26), for a projection (44), produced according to the following steps: a blank is deformed in a deformation process by deformation of material so as to form the recess (45), wherein the base (54) and the stop surface (47) and the circumferential wall are integrally connected to one another.

Abstract: A ball screw (7, 24), having a threaded spindle (8, 28) which is mounted in a rolling fashion by balls (9, 27) on a threaded nut (10, 26) and which is supported on an axial bearing (13, 25), wherein the threaded spindle (8, 28) is axially supported with its first bearing surface (18, 23), which is convexly shaped with a radius of curvature (R1), on a preferably conically designed second bearing surface (19, 22), wherein the first bearing surface (18, 23) and the second bearing surface (19, 22) make contact with one another along a contact path (37), wherein a quotient formed from the ratio of the radius of curvature (R1) to the radius (R2) of the contact path (37) assumes values of between 1.2 and 2.4 inclusive.

Abstract: A braking device, in particular for a motor vehicle, which has a brake disk, a brake caliper fitting around the brake disk, and two brake pads, which rest against the brake disk for the purpose of braking. One of the brake pads can be moved by a motor-driven ball screw which has a threaded spindle and a threaded nut. The ball screw is accommodated within the brake caliper. The threaded nut is connected to a piston which has the brake pad and which is seated on the threaded nut in such a way that it can be tilted relative to the threaded nut, and/or wherein the threaded spindle is mounted on the brake caliper in such a way that it can be tilted relative to the brake caliper.

Abstract: A suspension actuator (1) for positioning a movably mounted component of a motor vehicle suspension, including a first actuator component (4), which is to be connected to the movably mounted component, and a second actuator component (3), which is to be connected to a fixed suspension component, wherein both actuator components can be axially adjusted relative to one another via a ball-type linear drive (5), which includes a threaded spindle (6) and a nut (7) running thereon. Either the nut can be driven via a drive motor (10) for the axial adjustment of the threaded spindle or the spindle can be driven via a drive motor for axial adjustment of the nut.

Abstract: A ball screw (7, 24), having a threaded nut (10, 26) which is arranged on a threaded spindle (8, 28) and having a stop (43) for the circumferential abutment of the threaded nut (10, 26) in its stop position provided on the threaded spindle (8, 28), wherein the stop (43) has a first stop surface (47) assigned to the threaded nut (10, 26) and has a second stop surface (48) which is provided for abutting against the first stop surface (47) and which is assigned to the threaded spindle (8, 28), and, in the stop position, an axial overlap of the first stop surface (47) with the second stop surface (48) is provided, which overlap amounts to between 20% and 85% of the pitch of the threaded spindle (8, 28).
