  • Patent number: 9868327
    Abstract: A torsion hitch receiver is provided having a frame that has a portion that mounts to a vehicle. The frame includes an upper torsion tube that carries an upper torsion bar. Attached to the upper torsion tube is a torsion housing that affixes a lower torsion tube. The upper torsion bar has an upper torsion arm that rotates with the upper torsion bar, and a lower torsion bar, carried within the lower torsion tube, the lower torsion bar has lower torsion arms. Both upper and lower torsion arms attach to a receiver housing that can receive a draw bar. As weight is applied to the receiver housing, the torsion bars allow rotation. As the torsion bars rotate, the receiver housing moves up and down.
