Air suspension with lifting bag is a kind of which lifting bag can lift the axle up when the trailer is unloading , this function can save fuel and reduce damage on the road .
The current market of buses have suspension system consisting of either mechanical or air suspension system. Compared to its counterpart, air suspension system has significant benefits. Vehicle height can be maintained at a particular value irrespective of it load by varying the pressure and also standard coaches have a system called ferry lift. This allows the air suspension to be raised above the normal ride height level to originally aid loading and unloading the vehicle on and off ferries due to their steep ramps and risk of grounding out, but can be used on rough ground or on steep crests. Although the ferry lift may be installed on some buses, the Kneel Down facility is more common on public transport buses. This helps reduce the step height for easy ingress of passengers.The Kneel Down facility is also used when using the built in wheel chair ramps. Due to several advantages air suspension has been extensively used in commercial vehicles since 1980.
Introduction If we look at the different suspension systems used in motor vehicles today, the most apparent difference between them is that they are either mechanical or air suspension systems. Both types are, of course, incapable of meeting all technical requirements. If they are, however, directly compared, it soon becomes apparent that air suspension offers major benefits compared with mechanical suspension systems. As a result air suspension systems are used to an increasing extent in commercial vehicles. Benefits of Air Suspension Systems 1. By changing the bellows pressure, depending on the load carried on the vehicle, the distance between the road surface and the vehicle’s superstructure addresses the same level. This means that the boarding or loading height, and the headlight settings, remain constant. 2. Spring comfort remains almost unchanged across the whole of the loading range; again this is achieved by changing the bellows pressure. The passenger on a motor coach will always perceive the same pleasant type of oscillations. Sensitive loads can thus be carried without being severely damaged. The well-known “jumping” of an unladen or partially laden trailer no longer occurs if an air suspension system is used. 3. The stability of the steering system and the transfer of the braking forces are improved since all wheels always have good adhesion to the road surface. 4. The pressure in the air bellows, depending on the load the vehicle carries, is ideal for use in controlling automatic load-sensitive braking. 5. In the area of control for interchangeable platforms, air suspension systems are an excellent basis for cost-effective loading and unloading of containers. 6. The kneeling effect often required for routine buses can easily be achieved by venting the nearside air bellows
