The bus air suspension springs were derived from the need for improving thedriving comfort by absorbing librations, vibrations and sudden shocks in busescaused by structure of roads almost 50 years ago and the air suspension spring isused in almost all buses in Europe. We produce the air suspension springs to meetthe requirements for more comfortable driving and more optimum loading onvehicles.

The type of spring generally preferred for buses and light commercial vehicles is theroll springs. The roll springs are the springs having ultra spring sensitiveness. Theyprovide extremely comfortable suspension reaching high strokes without anyincrease in the operating diameter due to their long product lengths generally. Theplates and pistons produced in appropriate diameter and conic form may be easilymounted and demount to/from these products with both connection necks beingconic.However,the direction of the conic part with a narrow diameter must bemounted on the piston (axle-lower) and its direction with a wide diameter must bemounted on the plate (frame-upper) in the types produced in a conic form.

There are varied operating pressure intervals, connection heights, operatingspaces, operating frequencies and lifting forces for different areas of use.
