PURPOSE: A leveling system of an air suspension vehicle is provided to improve freedom of design and to easily perform mounting work by installing a valve mechanism to the inside of an air spring. CONSTITUTION: A leveling system of an air suspension vehicle has a valve mechanism(50) installed to the inside of an air bag(11) of an air spring(10). In the valve mechanism, an air supply line and an air exhaust line are opened by rack and pinion actions of according to compression or extension of the air spring. The valve mechanism comprises a rod(51) fixed to an upper bracket(12) of the air spring; rotating disks(52) rotatably mounted on the lower sides of the rod through a pin(53); and a rack bar(54) fixed to a lower bracket(13) of the air spring. The rotating disk forms a supply groove corresponding to the lower end of the supply line, to open the supply line, and an exhaust groove corresponding to the lower end of the exhaust line, to open the exhaust line. Pinions are integrally formed to the inner surface of the disks. The rack bar has a rack formed on the side and the rack bar is engaged with the pinion of the rotating disk. Thus, the height of the vehicle and the position of the vehicle are maintained regularly.
