An air spring includes a cover, a base element and a flexible bellows clamped in a pressure-tight fashion between the cover and base element. A level-measuring device, integrated at least partially into the bellows, detects the height of the air spring. The level-measuring device has at least the following: a) at least one angle sensor which is integrated into the bellows, is connected at least in a rotationally fixed fashion to the cover or the base element and has an element which can rotate with respect to a base, b) a mechanical coupling, which is connected, at one end, to the rotatable element of the angle sensor and at the other end, to the cover or to the piston, such that when the height of the air spring changes an angle of at least one element of the mechanical coupling is changed and the angle sensor generates an angle signal which is dependent on the change in angle of the element, c) an evaluation device which assigns the angle signal originating from the angle sensor to a height level of the air spring. |
