  • Patent number: 9221316
    Abstract: 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.
