PURPOSE: An air suspension system is provided to suppress frequent operation of a leveling valve by absorbing frequent height variations between the frame of a vehicle and a main shaft through substituting a lever connecting the leveling valve and the main shaft with a flexible component. CONSTITUTION: An air suspension system comprises an air spring(1), a leveling valve(10) and a lever(14). The air spring(1) is mounted between a body frame(12) and an axle(18), maintains a gap between the body frame(12) and the axle(18) and absorbs impacts transferred from a road surface. The leveling valve(10) is installed to provide and exhaust properly compressed air to the air spring(1) according to a distance from the body frame(12) and the axle(18). Both ends of the lever(14) are connected to a locker of the leveling valve(10) and a rod(16). One end of the rod(16) is connected to the axle(18). One end of the lever(14) connected to the locker of the leveling valve(10) is helically formed and made of elastic material.
