摘要:
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.
摘要:
The invention relates to a roll stabilizer for the chassis of a motor vehicle, comprising an actuator (3), which is mounted between anti-roll bar halves (1, 2) and which rotates these about a rotation axis in opposite directions as necessary. The curved path carriers (4, 5) of the actuator that are assigned to the roll stabilizer halves (1, 2) are each provided with a curved path (17, 18) inside of which a coupling element (13) is guided that can be displaced along these curved paths (17, 18) via an actuating drive (7, 10). The U-shaped or V-shaped curved path (18) of one curved path carrier (5) has two curved path branches (19, 20) that are arranged in a mirror symmetric manner in relation to a longitudinal central plane containing the rotation axis of the actuator (3).

摘要:
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. A brake unit (14, 28), which can be actuated by an external force on the suspension side and acts on the nut (7) or the spindle and rotates them, and which builds up a friction torque opposing a nut rotation or the spindle rotation, which acts between the nut (7) or the spindle (6) and a fixed actuator element (22, 35) or between a drive shaft of the drive motor (10) and a fixed actuator element (45) associated therewith, is provided.
摘要:
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. A tool operates on and reshapes the blank (57) from the exterior by exercising radial forces (F), whereby during the reshaping process the inner circumferential surface of the blank (57) is shaped according to the counter profile and to the projecting part (59) of the tool arbor (56) such that the screw-shaped track (4) and the deflecting recess (23) are formed.

摘要:
A spindle nut for a ball screw is provided, having a continuous ball track (1) for balls (2), a ball groove (3,14) for the balls (2) extending on an inner periphery of the spindle nut about the rotational axis thereof and along a helical line, the ball groove extending across at least one thread (4), and a diversion device (5), in order to divert with its diverting channel (9) balls (2) from one end of the thread (4) to the beginning of the thread (4). The spindle nut is provided with ball inlets (13, 16), on the one side connected to the ball groove (3, 14) and, on the other side connected to the diverting channel (9), with the ball groove (3, 14) and the ball inlet (13, 16) both having identical cross-sectional profiles.
