Abstract:

A vehicle suspension system couples an axle to a vehicle frame so that the axle pivots about a first location with respect to the frame when the axle has a first range of articulation. The axle pivots about a second location with respect to the frame extending laterally out from the first location when the axle has a second range of articulation greater than the first range of articulation. When the axle exceeds the second range of articulation, the suspension system retains the axle in a substantially rigid contact with the vehicle frame.
