Roll stabilizers as an example for chassis actuators are used for compensating or suppressing rolling movements of a vehicle about its longitudinal axis. Such rolling movements are caused, in particular, when driving around curves due to centrifugal forces. A chassis actuator device is provided, in particular, a roll stabilizer, for a vehicle with a flange connection between an actuator and a stabilization component. A holder-side positive-locking contour is arranged on a holder section of the flange connection and a flange-side positive-locking contour is arranged on a flange. The positive-locking contours together form a positive-locking connection in the circumferential direction about a torsion axis A, and the flange-side positive-locking contour is arranged on a flange-side lateral surface and/or the holder-side positive-locking contour is arranged on a holder-side lateral surface.

Chassis actuator device for a vehicle

Split roll stabilizer of a motor vehicle, between the two stabilizer parts () of which an actuator () for a torsion of the stabilizer parts () can be effectively disposed, a sensor () for determining the torsional moment acting in the stabilizer parts () being provided.

Split roll stabilizer

A spindle nut for a ball screw is provided, having a continuous ball track () for balls (), a ball groove () for the balls () 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 (), and a diversion device (), in order to divert with its diverting channel () balls () from one end of the thread () to the beginning of the thread (). The spindle nut is provided with ball inlets (), on the one side connected to the ball groove () and, on the other side connected to the diverting channel (), with the ball groove () and the ball inlet () both having identical cross-sectional profiles.

Method for producing a spindle nut for a ball screw

A divided roll stabilizer of a motor vehicle between whose two stabilizer parts () an actuator () can be arranged for a torsion of the stabilizer parts (). At least one of the stabilizer parts () is provided with a torsion transmitting connecting part () for connection to the actuator (), and the connecting part () is magnetically coded.

Divided roll stabilizer

A slewing motor for an active roll stabilizer, which can be connected by its drive to one stabilizer half, and which can be connected on the stator side to another stabilizer half of a divided stabilizer. A torsion element, whose rotational rigidity is lower than the rotational rigidity of the stabilizer, is effectively arranged between the drive and the one stabilizer half.

Geared motor for an active roll stabilizer

An electromechanical actuator, especially for an anti-roll bar of a motor vehicle, that has two actuator elements, which can be rotated relative to each other about a common rotational axis, for which purpose an electric motor and a gearbox coupled therewith are provided. The electric motor is arranged in an actuator element for transmitting a torque, and an output shaft of the gearbox is coupled to the other actuator element. A mechanical overload coupling is provided in the torque-transmitting load path from the electric motor to the gearbox output shaft.

Electromechanical actuator, especially for an anti-roll of a motor vehicle

A suspension actuator () for positioning a movably mounted component of a motor vehicle suspension, including a first actuator component (), which is to be connected to the movably mounted component, and a second actuator component (), 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 (), which includes a threaded spindle () and a nut () running thereon. Either the nut can be driven via a drive motor () 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 (), which can be actuated by an external force on the suspension side and acts on the nut () 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 () or the spindle () and a fixed actuator element () or between a drive shaft of the drive motor () and a fixed actuator element () associated therewith, is provided.

Suspension actuator

A ball screw drive which has a ball nut arranged on a spindle. The ball nut has a nut element and a deflecting element that deflects balls out of one end of an endless ball channel defined by the ball nut and the spindle to a beginning of the ball channel. The deflecting element is retained on the nut element through a clip. At least one clip leg of the clip has a first, resiliently biased section and a second section separated from the first section by a slit. The first section resiliently suspends the deflecting element on the nut element and the second section retains the clip inseparably on the deflecting element.

Ball screw

A ball screw is provided having a ball roller screw () and a screw nut () arranged thereon, whereby the balls () are arranged to endlessly circulate in a ball channel () defined by ball tracks () on the ball roller screw () and the screw nut (). The ball channel () includes a load section () wound about the ball roller screw (), the beginning and end of which are endlessly connected by a load-free return section (). A minimum of two and a maximum of four balls () are housed in a common ball cage (), the cage pockets () of which each house one of the balls (), whereby the ball cage () includes discs () at the axial ends thereof and between adjacent balls (), that engage the ball channels (), and provided on the sides thereof facing the balls () with a concave receptacle () for the balls ().

Ball screw, having a spindle nut () which may be provided on a recirculating ball screw () and on the inner circumference of which turns () of ball grooves (), helically wound around an axis, are provided in which balls () can roll, at least one return element (), arranged on the outer circumference of the spindle nut () and provided with a return duct () for the balls (), at its two ends connecting a start of a turn () to an end of a turn () in order to permit a continuous recirculation of the balls (), the return element () between its two ends being supported on a support (), the return element () being resiliently supported by means of at least one spring element () on the support ().
