    摘要： The invention relates to an air spring (1) comprising a cover (4), a base element (6) and with a flexible bellows (8) clamped in a pressure-tight fashion between the latter, and comprising a level-measuring device (10), integrated at least partially into the bellows (8), for detecting the height of the air spring (1). The invention proposes that the level-measuring device (10) has at least the following: a) at least one angle sensor (12) which is integrated into the bellows (8), is connected at least in a rotationally fixed fashion to the cover (4) or the base element (6) and has an element (14) which can rotate with respect to a base (16), b) a mechanical coupling (30, 30', 30", 30'", 30""), which is connected, at one end, to the rotatable element (14) of the angle sensor (12) and at the other end, to the cover (4) or to the piston (6), in such a way that when the height of the air spring (1) changes an angle (ω) of at least one element (30; 30a'; 30a"; 30a'"; 30a"") of the mechanical coupling (30, 30', 30", 30'", 30"") is changed and the angle sensor (12) generates an angle signal which is dependent on the change in angle of the element (30; 30a'; 30a"; 30a'"; 30a""), c) an evaluation device (18) which assigns the angle signal originating from the angle sensor (12) to a height level of the air spring (1).
