Abstract:
The invention relates to a wheel suspension for motor vehicles with level adjustment of the body, having a vertical adjusting device (22; 80) 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 (34) of at least one support spring (14), wherein the vertical adjusting device (22; 80) is outwardly sealed by at least one enclosing rubber-elastic bellows (50, 52; 100). 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 (54, 56; 102) enclosed by the bellows (50, 52; 100) is connected directly or indirectly to an auxiliary volume (66; 108) positioned outside of the bellows (50, 52; 100).
