Abstract: A controlled steering system includes a sliding carriage attached to the steering at least one steering rod. As the carriage slides from one side of the horizontal pivot pint of the towbar, the direction off steering with respect to the towbar reverses. Also, the distance of the sliding carriage from the horizontal pivot point controls the degree of steering. By controlling the movement of the sliding carriage in response to measurements of towbar angle, the backing process can be partially or completely automated.

Abstract: A steering system for steering a heavy haul trailer dolly comprising a turntable mounted on the dolly for connecting to another trailer unit. The dolly comprising a main frame, a wheel group mounted to the main frame, and a pivot frame mounted to the main frame between the turntable and the wheel group. A counter-steering linkage connects the pivot frame and the turntable. Hydraulic cylinders connect the pivot frame and the wheel group.
