ABSTRACT:
The exact spring height as well as the spring pressure can be determined with a single arrangement for the optimal utilization of the axle loads of a multi-axle air spring suspended vehicle and to control the distance between the chassis and the axle. An air spring (2) is equipped with an ultrasonic pulse/echo measuring system. The air spring (2) includes a transmitter/receiver component (14) arranged on the chassis and a first reference electrode (20) and a reflector component (16) fixed to the axle. The air spring height can be determined in a conventional manner from the relative value of the running times of the ultrasonic pulses which are traversed on the reference path and the measuring path. A second reference reflector (22) is mounted at a different distance to the first reference reflector (20). For the determination of pressure, the transmitting power or the receiving amplification of the second reference reflector (22) is controlled in such a manner that the amplitude (intensity) of the sonic waves, which are reflected from the first reference reflector (20), remains at a constant value. This amplitude (intensity) is measured via the sonic transducer (14).
