Abstract
A damping air spring and shock absorber combination for heavy-duty vehicle axle/suspension systems includes a damping air spring and a shock absorber both operatively attached to the axle/suspension system. The damping air spring primarily provides damping to the axle/suspension system over a first range of frequencies. The shock absorber primarily provides damping to the axle/suspension system over a second range of frequencies. The first range of frequencies is from about 0.0 Hz to about 6.0 Hz and the second range of frequencies is from about 0.0 Hz to about 13.0 Hz.
