Abstract
An axle assembly for transporting a load bearing frame includes a first axle operably coupled to an axle mount of the load bearing frame by a first articulation structure, and a second axle spaced a distance from the first axle and operably coupled to the axle mount by a second articulation structure. The first articulation structure is rotationally coupled to the axle mount by a first articulation connection, and the second articulation structure is rotationally coupled to the axle mount by a second articulation connection. A suspension system is operably coupled to both the first articulation structure and the second articulation structure. In a first mode of operation, the suspension system forms a substantially rigid connection between the first articulation structure and the second articulation structure. In response to an upward articulation of the first articulation structure towards the load bearing frame, the substantially rigid connection causes the second articulation structure to articulate down and away from the load bearing frame. In a second mode of operation, the suspension system articulates both the first articulation structure and the second articulation structure towards the load bearing frame.
