Abstract

The invention concerns a device for a vehicle, for height adjustment of a vehicle superstructure, which at one end has a first means for pivoting on a sprung mass (2) of the vehicle and at the other end a second means for pivoting on an unsprung mass (3) of the vehicle, a vibration damper (4) damping a relative movement of the sprung mass and unsprung masses (2, 3), and a self-pumping air spring (5) which supports the sprung and unsprung masses (2, 3) against each other in a sprung fashion. The vibration damper (4) according to the invention has a damping characteristic which is adjustable during operation, preferably steplessly adjustable. The invention also concerns a method for height adjustment of a vehicle superstructure by means of such a device.
