DESCRIPTION
Air springs have been used in heavy duty vehicle suspension systems for nearly a century, where they have been able to provide usefulness by taking advantage of the compressed air required for vehicle braking systems. Air springs have provided a two-fold advantage over mechanical leaf- or coil-springs. One advantage with air suspension is the extra comfort provided by being able to vary the air pressure inside the spring, which changes the spring rate, and therefore, ride quality. Additionally, because variable control over air pressure adjusts the deck or trailer height, aligning loading docks to the level of the deck is possible when dock plates are unavailable.
With changing loads, air spring reacts initially by changing the distance between air spring support and coach body. then actuating height monitoring valve( leveling valve ), either by taking the compressed air to the air spring or releasing air pressure from it to the atmosphere this process continues until the required height is maintained this mechanism ensures a constant floor height on coaches provided with air springs, irrespective of the load.
