In an air spring system of a motor vehicle having a pressure line extending between a compressor and a pressure storage or air springs of the motor vehicle, the pressure line includes a section between a dryer and the air springs with a variable flow cross-section and with one electromagnetically actuable switching valve arranged in parallel with the variable flow cross-section and providing unrestricted flow when opened.

A combined spring-and-shock-absorber system for supporting wheel suspensions or axles on a vehicle body has a tubular roll bellows (U-bellows) arranged between a wheel-bearing or wheel-controlling connection and a connection on the vehicle body side, the bellows being arranged between an outer bell and a rolling piston, the outer bell and the rolling piston, in each case, having at least partially varying diameters over the height of the corresponding component, and having walls that contact the tubular roll bellows. Both ends of the tubular roll bellows being sealingly secured on the rolling piston at segments having different diameters, the lower mounting section having a larger diameter than the upper mounting section. For this purpose, a tubular roll bellows is used, which is configured as a differential roll bellows, whose interior is filled with a fluid and communicates with a hydraulic accumulator supported on the chassis and/or vehicle body. On the basis of the present invention, a combined spring-and-shock-absorber system is developed, which contains a friction-free displacement device in a thin construction.

In a motor-vehicle spring-strut support bearing for mounting a piston rod of the spring strut to a vehicle support element, the piston is mounted in the support element to a connecting element which is connected to the support element by an annular resilient spring element disposed between the connecting element and the support element and axial stops are provided including a spherically curved surface on the support element, which limit axial movement of the piston rod upon compression of the spring strut by a vehicle wheel in one direction and upon rebound of the wheel in the opposite direction, the arrangement providing a force-centering support of the spring strut piston rod on the spring strut support.
