The invention relates to a threaded mechanism with rolling bodies that comprises a spindle rod (1), a spindle nut (4) at least partially enclosing said spindle rod, and a number of interposed rolling bodies (3). The inventive mechanism is especially characterized in that the spindle nut (4) is provided with an axial and a radial bearing that is adapted to receive both tilting motions of the spindle nut (4) about its longitudinal axis as well as radial motions at an angle to its longitudinal axis.

The invention relates to a roll stabiliser for the chassis of a motor vehicle. According to the invention, the actuator (3, 38) of said roll stabiliser, which can be actuated by means of independent energy as required, counteracts a roll. Said actuator (3, 38) comprises at least one additional energy accumulator (33a, 57), the stored energy of said accumulator also counteracting the roll.

The invention relates to a ball screw (1) comprising a ball caster spindle (3) and a driven spindle nut (2) arranged thereon. Balls (7) are arranged in a continuously rotatable manner in at least one endless ball channel (8), said ball channel (8) comprising a load section (9) which is wound around the ball caster spindle (3) and defined by ball tracks (10, 11) of the ball caster spindle (3) and the spindle nut (2), and a load-free recycling section (12) which continuously connects the beginning and end thereof. A regreasing device (15) which is arranged on the spindle nut (2) in a rotationally fixed manner supplies lubricant to the ball channel (8) using centrifugal force.

The invention relates to a spindle nut for a ball screw, comprising a continuous ball track (1) for balls (2), a ball groove (3, 14) for the balls (2), extending on the inner periphery of the spindle nut about the rotational axis thereof and along a helical line, said ball groove extending across at least one thread (4), and a diversion device (5). In the diverting channel (9) thereof, balls (2) are diverting from one end of a thread (4) to a beginning of a thread (4). The spindle nut is provided with ball inlets (13, 16) connected on one end to the ball groove (3, 14) and on the other end to the diverting channel (9). The ball groove (3, 14) and the ball inlet (13, 16) have identical cross-sectional profiles.

The invention relates to a roll stabiliser for the chassis of a motor vehicle, comprising an actuator (3) which is arranged between two halves of the stabiliser (1, 2) and rotates the same in relation to each other, as required, about a rotational axis. Said actuator (3) is provided with a failsafe device (34) which interconnects the two halves of the stabiliser (1, 2), as required, in a rotationally fixed manner.

Disclosed is a method for the production of a spindle nut (3) of a spherical thread drive mechanism. The inner circumference of said spindle nut (3) comprises at least one screw-shaped track (4) which is formed thereupon as a single piece and the threads (38) of which are separated by means of shoulders (6). Said shoulder (6) is interrupted at least at one peripheral position by a deflecting recess (23) in order to redirect balls (13) from one thread into an adjacent thread (38). The inventive method comprises the following steps: a tool arbor (56), the outer circumference of which is provided with a counter-profile of the screw-shaped track (4) and a projecting part (59) for each deflecting recess, is disposed inside a hollow blank (57); a tool exercising radial forces (F) acts upon and reshapes the blank (57) from the outside, the inner circumferential surface of the blank (57) being shaped according to the counter-profile and the projecting part (59) of the tool arbor (56) during the reshaping process such that the screw-shaped track (4) and the deflecting recess (23) are formed. The invention also relates to a device for carrying out said method.

The invention relates to a device for modifying the wheel camber of a wheel (1) on a motor vehicle, in which the wheel (1) is pivotally mounted on a wheel carrier (5, 51) by means of a pivot bearing (4, 50). According to the invention, a pivoting plane that is described by the pivot bearing (4, 50) extends in an approximately transversal manner to the central plane (E) of the wheel, the position of a virtual centre of rotation (D) of the pivot bearing (4, 50) lying above the wheel contact plane and on the side of the central plane (E) of the wheel that faces towards the vehicle.

The invention relates to a release bearing (8) used in a clutch release device (1) for actuating a friction clutch in automobiles. In order to seal an annular gap (14) that is regulated between the inner ring (9a) and the outer ring (10) of the release bearing (8), a sealing element (17a) is provided which is fixed to the inner ring (9a). In order to mount the sealing element (17a) on the inner ring (9a) in a non-positive manner, a preload spring (13) is supported on a branch (20) of the sealing element (17a).
