PURPOSE: An air spring apparatus for a vehicle is provided to minimize the length deformation of bellows by vertically moving bellows in accordance with the vertical movement of a lower arm. CONSTITUTION: An air spring apparatus for a vehicle(1) comprises a cap unit(10), bellows(20), a piston(30), and a bearing unit(40). The cap unit is equipped on a lower arm. The bellows are equipped on the upper part of the cap unit and rotate according to the movement of the cap unit. The lengths of the bellows are variable. The piston is positioned in the upper part of the cap unit and is combined with the bellows. The bearing unit is positioned on the upper part of the piston. The bearing unit rotates the piston following to the movement of the cap unit and guides the upward/downward movements of the piston in accordance with the rotation of the piston. |
