Claim:
1. An air spring, comprising: a distance measurement sensor; an energy transforming unit comprising a propeller and a generator; a first mounting element being adapted for being mounted to a first vehicle portion; a second mounting element being adapted for being mounted to a second vehicle portion; an air volume arranged between the first mounting element and the second mounting element, wherein the energy transforming unit is adapted to transform a transition of the air spring from a first state (s wherein the propeller is adapted for being moved when transitioning from the first state to the second state and is adapted to drive the generator, wherein the generator generates the electrical energy; and wherein the distance measurement sensor is arranged within and receives the generated electrical energy within the air volume of the air spring; and a pneumatic pressure generator adapted for varying air pressure within the air spring, wherein the pneumatic pressure generator is positioned within the air volume of the air spring, and wherein the pneumatic pressure generator is adapted to modulate a pressure in the air volume when the generated electrical energy is below a threshold.
