ABSTRACT:
A four-wheel steering system in a wheeled vehicle includes a lateral control shaft operatively connected at its opposite ends with a set of rear steerable road wheels, and a rear-wheel steering mechanism operatively connected to a front-wheel steering linkage for effecting axial displacement of the control shaft in response to operation of the front-wheel steering linkage. In the rear-wheel steering mechanism, a hydraulic power cylinder is adapted to control axial displacement of the control shaft in such a manner that the control shaft is returned to and retained in a neutral position in the occurrence of unexpected trouble in a hydraulic control circuit of the power cylinder to retain the rear road wheels in their neutral positions.
