Abstract:
1. An air spring for vehicle running gear, comprising an air spring cover and a rolling piston, wherein the air spring cover and the rolling piston are connected by an air spring bellows, wherein the air spring cover has a first, body-side clamping region and a second, piston-side clamping region for the air spring bellows, wherein the first and the second clamping region are designed to receive a first clamping ring and a second clamping ring for clamping the air spring bellows, wherein the first clamping ring and the second clamping ring are designed to fix the air spring bellows on the air spring cover, wherein the rolling piston and the air spring bellows have a common first air volume in the inner space thereof, wherein the end of the rolling piston closest to the running gear has a third clamping region, wherein the third clamping region is designed to receive a third clamping ring, wherein the third clamping ring is designed to seal off the first air volume from the external environment, wherein the air spring cover has a second air volume, wherein the air spring bellows forms an outer wall of the first air volume and of the second air volume, with the result that the first air volume and the second air volume are sealed off from an external environment, wherein the second clamping ring is arranged in such a way that the first air volume is spatially separated from the second air volume, wherein the air spring cover is designed to accommodate a switching valve, which is designed to allow a first air path between the first air volume and the second air volume in one operating state, thus enabling the second air volume to be linked to the first air volume.
