Abstract
The invention relates to a wheel suspension for motor vehicles with level adjustment of the body, having a vertical adjusting device () which is disposed between a wheel guide element and the superstructure of the motor vehicle and which is particularly designed as a ball screw mechanism driven by an electric motor and acts on an adjusting plate spring () of at least one support spring (), wherein the vertical adjusting device () is outwardly sealed by at least one enclosing rubber-elastic bellows (). In order to prevent deformation of the at least one bellows and ingress of dirt or moisture into the vertical adjusting device, the invention proposes that the interior space () enclosed by the bellows () is connected directly or indirectly to an auxiliary volume () positioned outside of the bellows ().
