Abstract
A header transport steering system is provided that allows the tongue of the header transport to pivot and translates the movement of the tongue to all of the wheels of the header transport. Front steering linkages are coupled to the tongue, and are configured to oscillate front wheels in response to rotation of the tongue. Walking tandem beams are connected to the frame and are configured to rotate in height with respect to the frame.
Claims15
A header transport steering system comprising:
- a frame comprising a front support beam and a rear support beam;
- a tongue pivotably coupled to said front support beam of said frame such that said tongue is capable of rotating about a coupling;
- a plurality of front wheels coupled with said frame;
- a plurality of rear wheels coupled with said frame;
- a front steering linkage coupled to said tongue and configured to oscillate said plurality of front wheels in response to rotation of said tongue;
- a plurality of walking tandem beams coupled to said rear support beam and configured to rotate in relation to said rear support beam;
- a front-to-rear linkage coupled to said front steering linkage and said rear support beam;
- and
- a plurality of rear connecting links coupled to at least one of said walking tandem beams, wherein each rear connecting link is configured to rotate in relation to said walking tandem beam, wherein each walking tandem beam is configured to rotate independently in relation to said rear support beam.
