Abstract: A level control for vehicles has at least one air spring cushioning a vehicle body relative to a vehicle axle. A compressed air generator is connected to the air spring by an air dryer and to the atmosphere by a check valve opening in the intake direction of the generator. The air spring can be connected to the atmosphere for discharge via a pneumatically controllable first directional valve. The air spring pressure is applied to a pneumatic control input of the first directional valve via a second controllable directional valve. The input of the first directional valve can be connected to the atmosphere for ending discharge of the spring. A line with a compressed air accumulator branches off from the air spring supply line via a first changeover valve. The accumulator is connected to the intake side of the generator via a second changeover valve.

Abstract: According to a method for controlling the air volume in a closed pneumatic spring system of a vehicle, an air-powered pump supplies at least two pneumatic springs and/or a compressed air reservoir with a specific air volume as needed such that the air pressure prevailing in the respective pneumatic spring and/or the compressed air reservoir is at a level which causes a vehicle body resting on the pneumatic spring to be positioned at a desired distance from the roadway or the vehicle axle. In order to obtain largely constant control velocities at different load conditions of the vehicle while using a smaller compressed air reservoir than in previously known systems, the pneumatic spring pressure (P) is measured in at least two of the pneumatic springs, the distance (HN, NN, TN) of the vehicle body to the roadway or the vehicle axle is determined, the axle load (AL) of at least one vehicle axle is determined from the pneumatic spring pressure (P) and the distance (HN, NN, TN) of the vehicle body to the roadway or the vehicle axle, a target system air volume (PV_SOLL) is determined in accordance with the respective axle load (AL), and the actual system air volume is adjusted to said target system air volume by actuating the air-powered pump or a relief valve.

Abstract: A sensor for a height control system in a trailing arm suspension uses a transducer to detect changes in position of a trailing arm relative to a vehicle and sends a proportional signal to a microprocessor that, in turn, actuates a pneumatic valve operably connected to an air spring between the trailing arm and the vehicle. The transducer includes an optical bridge, a variable capacitor, or a flexible variable resistor.
