Abstract: A torsion gooseneck coupler has a pin box that is designed to be affixed to an existing trailer. The pin box has a pin box torsion end and a lower assembly that each have a corresponding torsion bar. The torsion bars extend outwardly where each affixes to a corresponding torsion arm. The lower assembly is designed to affix to a towing vehicle. The lower assembly has an upper and a lower torsion tube that each has a corresponding torsion bar. The upper torsion arm affixes the upper torsion bar of the pin box assembly to the upper torsion bar of the lower assembly. Correspondingly, a lower torsion arm affixes the lower torsion bars of the pin box assembly to the lower assembly. The torsion tubes and bars resist rotation and cooperate to allow limited movement and provide resistance to forces along the axes of the upper and lower assemblies.

Abstract: A torsion receiver hitch is provided having a drawbar portion and a ball mount portion. The drawbar portion can affix to a towing vehicle and the ball mount portion can receive and affix a trailer. The drawbar portion is coupled to the ball mount portion with torsion arms that are affixed to torsion bars. The torsion bars are carried in corresponding torsion tubes affixed to the drawbar and ball mount portion. The ball mount portion can move with respect to the drawbar portion between a compression and tension position. The ball mount portion and drawbar portion remain parallel between the compression and tension position. Located between the compression and tension positions is a rest position. The rest position corresponds to no force being applied between the drawbar portion and ball mount portion.

Abstract: A torsion trailer coupler is affixed to a trailer between the tongue and an adjustable coupler. The torsion trailer coupler has a trailer side that affixes to the trailer and a coupler side that affixes to the adjustable coupler. The trailer side has torsion tubes that carry torsion bars and the coupler side has torsion tubes that carry torsion bars. The torsion bars between the trailer and coupler side are connected with torsion arms. The torsion trailer coupler moves between an unloaded position where the torsion bars and arms are at rest and a loaded position where force is applied between the sides and the torsion bars rotate about their central axes. The torsion bars, arms and sides cooperate to absorb transient forces between a towing vehicle and the tongue of the trailer.
