PNEUMATIC SPRING UNIT

The invention relates to wireless transmission of control signals for automatic level regulation in an air suspension system. Preferably, an air spring bellows unit (4) is used, in which a valve unit (5), a control unit (12) and an air spring bellows (2) form a common structural unit, which is held on a support (83) of the commercial vehicle. According to the invention, the air spring bellows unit (4) has a transmitter and/or receiver for wireless signal transmission, whereby a control signal from a remotely arranged control unit can be transmitted wirelessly to the air spring bellows unit (4) via the receiver.
