ABSTRACT:
A level control arrangement for motor vehicles having air springs which are functionally responsive to the vehicle load. A predetermined distance of the vehicle frame from the vehicle axis can be maintained by charging or discharging the air springs. The control arrangement includes a safety valve which can be controlled by the pressure in the air springs. When the vehicle is overloaded, or if a malfunction occurs in the control apparatus of the level control arrangement, the safety valve limits the pressure in the air springs to a preselected maximum safe pressure.
