  • Patent number: 7077413
    Abstract: Spring suspension for interconnecting an axle to the frame of a commercial, land-based and wheeled vehicle. An end support for an axle is included that has a cantilever spring interconnected by an interposed axle holder to an air-spring bridge. The cantilever spring extends forwardly; that is, toward the front end of the incorporating vehicle, from the axle holder. Oppositely, the bridge extends rearwardly from the axle holder. The forwardly extending cantilever spring elongately extends between two terminal ends thereof. These two ends constitute a front frame-secured end and a back axle holder-secured end. The rearwardly projecting bridge extends between its own two terminal ends, and constitutes a front axle holder-secured end and a back air-spring secured end. The front frame secured end of the cantilever spring is distantly positioned away from the back air-spring supported end of the bridge member.
