A pneumatic suspension, has at least the following components, an air-spring cover, air-spring piston, air-spring bellows in the form of axial bellows or transverse bellows which form a first air-spring loop, a vibration damper and a connection to the chassis. The pneumatic suspension has an articulated component located on the air-spring cover in the vicinity of the air-spring bellows. The component allows pivotal displacements when under pressure and forms a second air-spring loop which extends substantially in a radial direction. It also relates to advantageous variants of the articulated component, both for the axial bellows with an external guide and for the transverse bellows without an external guide. It relates to the use of a supporting bearing with a connection to the axial bellows. The pneumatic suspension is used in particular for the front axle of a motor vehicle.
