ABSTRACT:
An anti-sway trailer hitch for connecting a trailer to a tow vehicle. The hitch includes a first pivotal element attached to the tow vehicle and a second pivotal element attached to the trailer with a set of a converging link assembly on the first element connecting it to the second element. The converging link assembly projects the effective pivot point forward adjacent the rear axle of the tow vehicle and prevents lateral sway while allowing changes in the angular relationship between the two elements as the tow vehicle and trailer negotiate turns. The second pivotal element includes a yoke attached to the trailer frame. The yoke includes Spaced apart side members with a hitch ball mount in sliding engagement with the side members. The trailer is attached to the hitch ball. A pivotally attached strut extends between the first pivotal element and the-hitch ball mount. As the radius of the Converging links shortens or lengthens during and after turns, and the yoke is drawn toward or away from the tow vehicle, the strut maintains the hitch ball mount, with the trailer attached thereto, at a predetermined distance from the tow vehicle. The strut also reduces push-pull stresses on the converging link assembly by directing those stresses to the tow vehicle hitch bar.
