Abstract
A device for the suspension and for roll stabilization of motor vehicles achieves the required roll stiffness as well as the required lift stiffness without any additional springs by coordinating the ratio of the piston areas to the piston ring areas of the spring cylinders with simultaneous active engagement by an actuator integrated between the cross-wired lines.
Claims4
A device for roll stabilization and suspension of a motor vehicle, the motor vehicle including at least one vehicle wheel, comprising:
- an active suspension system acted upon by a pressure medium, each vehicle wheel being connected to a body of the motor vehicle via the active suspension system, the active suspension system including:
- a plurality of spring cylinders, piston areas and ring areas of the spring cylinders being configured in a ratio so that additional stabilizers and springs are unnecessary;
- lines cross-connecting the spring cylinders via damping elements and hydraulic accumulators provided in the lines;
- and
- an actuator connecting the cross-connected lines.
