Abstract
A steering system for a trailer is disclosed. A drawbar is attached to an elongated slide, with the slide attached to the trailer for rotation about a pivot axis. A carriage is mounted for movement along the slide and between ends of the slide. At least one control rod extends between the carriage and a steered wheel of the trailer. With the carriage positioned to one side of the pivot axis, the trailer wheels are steered in the direction of sideways towbar displacement when towed, and with the carriage positioned to the other side of the pivot axis, the trailer wheels are steered in the opposite direction of sideways towbar displacement when backed. An electrical, hydraulic, pneumatic or manual actuator may be used to move and position the carriage on the slide.
