CHASSIS AIR-SUSPENSION DEVICE FOR SUPPORTING A CHASSIS OF A UTILITY VEHICLE ON RUNNING GEAR, INCLUDING LEVEL CONTROL

The invention relates to a chassis air-suspension device (1) for supporting a chassis of a utility vehicle (2) on running gear, including level control. The device comprises at least the following: atleast one central electronic control unit (24c) which predetermines at least one desired level signal characterizing a desired level for at least one section of the chassis, at least one level sensor(14, 16a, 16b) which produces an actual level signal characterizing an actual level of the at least one section of the chassis, at least one air-spring bellows (12a, 12b) which supports the at leastone section of the chassis in relation to the running gear, and at least one compressed-air reservoir. According to the invention, the chassis air-suspension device (1) is constructed modularly and comprises, as modules, at least the central electronic control unit (24c) and additionally at least one electropneumatic air-suspension module (18, 20), wherein the at least one electropneumatic air-suspension module (18, 20) is
