METHOD FOR MONITORING THE WEAR OF AN AIR SUSPENSION FOR MOTOR VEHICLES
The invention relates to a method for monitoring the wear of an air suspension for motor vehicles, wherein a filling volume of a spring bellows (4) determines a level position (5) of an air spring (3) and the level position (5) is continuously detected by a height sensor (10). The invention provides for comparing the level position (5) detected by the height sensor (10) with a predetermined upper level position value (14) for a high level position and a predetermined lower level position value (15) for a low level position. Instances of level attainment, (25) when the detected level position (5) exceeds the upper level position value (14) or the detected level position (5) falls below the lower level position value (15), are counted (11, 12). From the count (11, 12) of the instances of level attainment (25), a wear status (17) of the air suspension is concluded.
