摘要： A two speed steering system for use with articulated vehicles, characterized by a steering wheel; a power steering servo; primary and secondary controls carried by one section of the articulated vehicle for controlling the speed with which the power steering servo steers; a double bar link that is pivotally connected with the primary and secondary controls and with an interconnection link between it and the other section of the vehicle; the interconnection link being disposed laterally from the pivot connection so that it tends to restore the double bar link in response to actual steer imparted to the sections of the articulated vehicle. The primary control has a weak spring that permits its movement, within its limits, before movement of the secondary control, with its stronger spring, is effected. Thus, a first speed of steering is effected by the primary control, but if a greater magnitude is signaled than the primary control is adapted to effect, the secondary control is brought into play to speed up the steering. Also disclosed are specific and preferred embodiments of apparatus.
