A pneumatically damped vehicle suspension system. The suspension system provides damping which is load-dependent, i.e., the amount of damping varies in approximate proportion to the load supported by the suspension system, thereby maintaining a nearly constant fraction of critical damping over the normal range of operating loads. The damping provided by the system is also frequency-dependent, a characteristic not achievable with hydraulic dampers. Two independent damping circuits provide maximum damping at the suspension's two resonant frequencies, or modes of vibration-the bounce mode and the axlehop mode. Relatively little damping is provided at other frequencies, resulting in improved isolation of road inputs.
