Abstract
A damping air spring for heavy-duty vehicle axle/suspension systems. The damping air spring includes a first chamber and a second chamber and at least one opening between the first chamber and second chamber to provide restricted fluid communication between the first chamber and the second chamber. An adsorptive material is disposed within the first chamber or the second chamber and works in conjunction with the at least one opening to provide damping characteristics to the air spring over a first and second critical range of frequencies.
