Abstract: A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.

Abstract: A roll stabilization system (1) for a motor vehicle which has a DC voltage converter (6) associated with an electric roll stabilizer (2). By way of the DC voltage converter, a feed voltage can be transformed into a supply voltage for the roll stabilizer (2). To produce as compact a structure as possible, the DC voltage converter (6) is integrated in the electric roll stabilizer (2).

Abstract: A vibration damper with a piston, a piston rod fastened to the piston, a working chamber divided by the piston into a first working chamber and second working chamber, and a generator drivable by movement of the piston rod. The damping force of the vibration damper can be influenced by energization of the generator. An energizable component part is provided that short-circuits the windings of the generator when unenergized and cancels the short circuit when energized.

Abstract: A preloading device for a piston valve of a vibration damper includes a spring element which is fitted by an inner diameter onto a radially inner centering device which serves for inner centering of the spring element in the installed state of the preloading device. To provide a preloading device for a piston valve by which a reliable inner centering of a spring element can be ensured but which can be placed with low expenditure on assembly at the same time, the spring element is axially fixed at the centering device via retaining means in that the retaining means at least partially enclose the spring element axially on both sides and are rigidly connected to the centering device in each instance.

Abstract: Energy-recuperating vibration damper having a cylinder in which a displacer executes a limited operating movement in a working chamber so that a pressurized fluid is supplied to a fluid motor which drives a generator. A compensation chamber compensates for a change in volume of the pressurized fluid. A pressure accumulator is provided in addition to the compensation chamber, which pressure accumulator communicates with and is parallel-connected to the fluid motor.
