ABSTRACT:
In many instances it has been a recent trend to incorporate the use of electronic controls into various machine functions to reduce the fatigue of an operator. When incorporated into the steering functions of a machine, the electronic controls often do not provide an operator with an "automotive" feel and thus do not work as well in some machine applications as they do in others. The present invention incorporates a mechanical feedback through the steering controls to provide the operator with a feel similar to that of an automotive environment. In addition, the steering controls operate in a manner which provides a variable ratio of steering wheel rotation to steering control valve actuation depending upon the articulation angle of the machine. In so doing, the function of the steering controls will vary with and enhance the operation of each specific mode of machine operation.
