Abstract

A double-acting, weight distributing trailer hitch (10) includes a drawbar assembly (20) and a hitchhead assembly (16). The drawbar assembly is releasably connected to the tow vehicle and includes a first coupling component (30) at its rearward end. The hitchhead assembly includes a second coupling component (88) and a rearwardly extending yoke (72). A drawbar extension (66) is connected to the yoke. The drawbar extension is pivotally mounted to the hitch ball (46) along a first horizontal axis (68) that is transverse to the direction of travel. A rearward portion of the drawbar extension is pivotally interconnected to the trailer along a pivot (302) defining a second horizontal axis, which is parallel to the first horizontal axis and located behind the hitch ball.
This creates an overlap between the forward end of the trailer and the drawbar extension. A coil spring assembly (300) dampens movement of the trailer.
