초록 ▼

A two wheeled trailer is provided with steerable wheels which are hydraulically actuatable according to the articulation angle between the trailer and a towing vehicle and to the forward and reverse mode of travel of these vehicles. In one embodiment, the angle to which the wheels are steered in response to the detected articulation angle may be less for forward travel than for reverse. Also, the wheels may be caused to assume a substantially straight ahead, non-steering configuration at forward speeds above a particular set point, with the steering automatically resumable upon lowering of the speed below another set point. Still another embodiment provides for steering of the wheels, whenever there is a transition between forward and reverse and an articulation angle exists, in a manner that prevents “crabbing”of the trailer relative to the towing vehicle.

대표청구항 ▼

An apparatus for steering the wheels of a two wheel trailer, and comprising: means for detecting an articulation angle between said trailer and a towing vehicle; means for steering said wheels by changing a wheel steering angle automatically according to changes in said articulation angle; means for identifying forward and rearward directions of travel of said trailer; a fluid circuit having a motive fluid for effecting said steering in response to said detecting and for interconnecting said angle detecting and said steering via said circuit; valve means for controlling a direction of flow of said motive fluid; and means for controlling routing of said motive fluid through said circuit via said valve means and automatically according to each of said directions of travel so as to provide a particular sense of said wheel steering angle according to said direction of travel.
