Sealing and functional testing of stop valve in vehicle pneumatic spring arrangement involves determining axle/chassis distance after opening valve and comparing with demand value

摘要

The method involves setting a displacement at individual gas springs (10) for which at least one damping element is compressed with the valve (22) open, setting the gas springs to part of their total displacement between damping elements after closing the valve and determining the distance between the axle and vehicle chassis after opening the valve using a measurement device and comparing with a demand value.
