Air spring and assembling device and method thereof

The invention discloses an air spring and an assembling device and method thereof, and relates to the field of automobile air springs. The air spring comprises an air bag, a guide sleeve and an elastic mechanism; the guide sleeve is sleeved on the outer ring of the air bag; and the elastic mechanism is supported in an inner cavity of the air bag, and the elastic mechanism can open the air bag and press the air bag and the guide sleeve together in a natural state. The air spring provided by the invention has the advantages that the problems that a traditional pressing ring is difficult to enter an air bag due to the fixed size, accurate positioning is difficult, and the pressing ring and the air bag are prone to distortion after assembly are solved, and the assembly effect is good. 本发明公开了一种空气弹簧及其装配装置、装配方法，涉及汽车空气弹簧领域，空气弹簧包括气囊、导套、弹性机构；所述导套套在所述气囊的外圈；所述弹性机构支撑在所述气囊的内部空腔中，所述弹性机构自然状态下能够将所述气囊撑开并与所述导套压在一起。本发明的优点在于：克服了传统压环由于尺寸固定导致的难以进入气囊、准确定位难以及装配后压环和气囊容易扭曲等问题，装配效果好。
