Abstract
A trailer hitch assembly for connecting a towing vehicle to a towed trailer having symmetrical anti-sway features. The assembly includes a hitch ball rigidly affixed to a hitch beam extending transversely from the rear of the towing vehicle. A pair of spring-biased telescopic compressible and extendable control rods are connected to each end of the hitch beam and at their other ends to a control beam. A hitch bar is connected to the hitch ball on the towing vehicle and pivotally connected to the forward end of a trailer coupler that intersects and is pivotally connected to the central portion of the control beam by a pivot member. The pivot member is integral with the control beam and includes a control arm having a roller engaged with a downwardly opening slotted rearward end of the hitch bar. The trailer coupler includes a trailer hitch ball to which a trailer coupler socket is connected, with the trailer coupler socket being rigidly affixed to the tongue or frame of the towed vehicle.
