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, which comprises at least the following: at least 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 least one 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 provided with an integrated module solenoid valve device (22c, 22d) and with an electronic module control unit (24c, 24d) integrated in the module solenoid valve device (22c, 22d) for control purposes, wherein the electronic module control unit (24c, 24d) processes the at least one desired level signal and the at least one actual level signal, and wherein the module solenoid valve device (22c, 22d) is connected to the at least one air-spring bellows (12a, 12b) and to the at least one compressed-air reservoir, and wherein the electronic module control unit (24c, 24d) is designed so as to control the module solenoid valve device (22c, 22d) depending on the at least one actual level signal and the at least one desired level signal in such a manner that, by ventilating the at least one air-spring bellows (12a, 12b) with compressed air from the at least one compressed-air reservoir or by venting the at least one air-spring bellows (12a, 12b) into a pressure sink (40c, 40d), the actual level of the at least one section of the chassis is adapted to the desired level.
