A first embodiment of a vehicle air bag spring suspension system utilizing a swing arm as a member of a four-bar linkage subsystem wherein the suspension system with the airbag spring is compressed by the linkage opposite the swing arm's fulcral point relative the supported wheel. The air bag further serves as an inherently, partially dampened spring having a non-linear spring compression rate, so as to firmly keep the vehicle tires firmly planted to a rough surface, with the system further benefitting from both the reduced total and unsprung weight of the air bag system and the higher frequency response of the air bag spring. A second embodiment employs two actuator arms per wheel, wherein one inside actuator arm contacts a fixed air bag spring and cooperates with the other outside actuator arm and a rotating actuator shaft inside a frame tube to dampen wheel movement.
