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 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: Method for producing a spindle nut of a ball screw, by provided the circumference of the nut with at least one through-opening for receiving a deflecting piece for balls of the ball screw. A hole punch arranged in the spindle nut and operable to punch out the through-opening from radially inward to radially outward through the casing of the spindle nut.

Abstract: A vehicle roll stabilizer for the chassis of a motor vehicle is provided, with its actuator (3, 38) being energized with independent energy, as necessary, for counteracting a roll. The actuator (3, 38) is provided with at least one additional energy accumulator (33a, 57), with its stored energy additionally counteracting the roll.

Abstract: Method for the production of a spindle nut (3) of a spherical thread drive mechanism, whereby the spindle nut (3) has at least one screw-shaped track (4) formed as a single piece on its inner circumference, whose threads (38) are limited by shoulders (6). The shoulder (6) is interrupted by a deflecting recess (23) at at least one deflecting position, in order to deflect balls (13) out of one thread into an adjacent thread (38). The method includes locating a tool arbor (56) in a hollow blank (57), whereby the tool arbor (56) has on its outer circumference a counter profile of the screw-shaped track (4) and a projecting part (59) for each deflecting recess.

Abstract: Roll stabilizer for the chassis of a motor vehicle having an actuator (3) arranged between stabilizer halves (1, 2) and rotating them relative to one another around a rotational axis, when necessary. The actuator (3) is provided with a failsafe device (34), which connects the two stabilizer halves (1, 2) in a torque proof manner, when necessary.

Abstract: A hydraulic system for a motor vehicle has at least one pressure restricting valve with a housing that has two or more connections. At least one conduit cross-section in the housing can be closed by means of a closing body that is movable axially against the action of an energy accumulator. At least a part of the axial travel of the closing body is damped by means of a damping device.
