Structure et procédé de positionnement de transport à essieu directeur

摘要

A steering axle assembly (18) of a work machine such as an agricultural harvester (10) includes telescoping axles (30, 32) and wheel assemblies (24, 26) on the telescoping axles (30, 23), with front and rear hydraulic cylinders (50, 52, 70, 72) for axially and angularly adjusting positions of the wheel hub assemblies, including steering the hubs to angles sufficient to minimize a width of the steering axle assembly (18) for transport.
