Abstract
The subject invention reveals an air spring arrangement comprising: a first mounting member, a second mounting member, an air spring volume, a height sensor, a controllable valve, a position controllable drive, wherein the first mounting member and the second mounting member are arranged so as to mount the air spring volume to corresponding vehicle members, wherein the height sensor is arranged so as to sense a distance between the first mounting member and the second mounting member, wherein the controllable valve is arranged so as to connect the inside of the air spring volume with the outside of the air spring volume, wherein the position controllable drive is arranged so as to drive the controllable valve with respect to an opening grade of the controllable valve, and wherein the position controllable drive is controlled based on the sensed distance between the first mounting member and the second mounting member.
