Abstract
An anti-sway trailer hitch connection is provided for use between a towing vehicle and a trailer and includes structure whereby slight left and right lateral movement of the forward end of the towing vehicle will not be translated into right and left lateral movement, respectively, of the forward end of the trailer, and thereby eliminates the tendency of a trailer to sway back and forth while a towing vehicle changes lanes on a highway or is acted on by cross-wind gusts from the passing of a large vehicle.
