Abstract
The invention concerns a pneumatic springing system for vehicles with at least a first and a second part (3, 4), wherein the two parts (3, 4) are mounted vibration-mobile and pneumatically sprung in relation to each other by means of at least one pneumatic spring (8), wherein a first control device (10) is arranged to supply air to and extract air from the pneumatic spring (8), which carries out the extraction of air after a first travel end zone (62) of the springing system has been reached in which the pneumatic spring (8) is in a compressed state, and which carries out the supply of air after a second travel end zone (63) of the springing system has been reached in which the pneumatic spring (8) is in an extended state, wherein a second control device (20) is provided to supply air to the pneumatic spring (8) and disable the extraction of air from the pneumatic spring (8) during a pre-determinable first time interval (61) after a first travel end stop (58) in the first travel end zone (62) has been reached for the first time, and/or a third control device (30) is provided to extract air from the pneumatic spring (8) and disable the supply of air to the pneumatic spring (8) durin…
