ABSTRACT:
A thin gooseneck assembly is provided for use in the chassis of a semi-trailer intended for hauling freight containers. The gooseneck assembly is formed by a fabricated tube extending longitudinally to define substantially the entire length of the gooseneck. The fabricated tube includes a lower plate having a pair of upstanding side defining flanges. A rearward portion of the lower plate includes a pair of longitudinal slots for receiving in fixed relation the web of a longitudinal beam which extends from the gooseneck to the rearward end of the semi-trailer. The top flange of each longitudinal beam is fixed to an upper surface of the lower plate so that a lower surface of each top flange is in surface-to-surface contact with the lower plate upper surface. An upper plate is positioned parallel to the lower plate and fixed to upper portions of the side-defining flanges. A kingpin for coupling the chassis to a tractor fifth wheel projects downward through the lower plate of the fabricated tube. A rearward margin of the upper plate of the gooseneck assembly includes a downwardly inclined portion joining the upper plate to an upper surface of the top flanges of the longitudinal beams.
