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

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 clamping device includes a first clamping plate and a second clamping plate, the first clamping plate being rotatable between a released position and a clamped position in relation to the second clamping plate. The clamping device further includes a rolling body which establishes contact between the first and second clamping plates. The second clamping plate includes a clamping ramp with a contour for the rolling body so that when the clamping plates are rotated in relation to each other, the space between the clamping plates changes. The first clamping plate has a surface which forms a plane on which the rolling body rolls from the released position to the clamped position.

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

Roll stabilizer for the chassis of a motor vehicle

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