Abstract
The disclosure relates to the configuration and method of fabrication of the forward underbody of a semitrailer. A lower plate of the underbody has two inverted channels welded thereto. A kingpin extends downwardly through an aperture in the lower plate and is welded in position between the two inverted channels. The kingpin and the channels are braced by laterally spaced gussets which are welded in position thereto. A top plate with angular edge flanges fills the space between the inverted channels, the edge engaging sloping corners of the channels and forming a right angle therwith. Continuous welds secure the top plate to the channels which are below the top surface thereof. The assembly thus provided is extremely strong, light in weight, and capable of assembly with conventional welding equipment and without need of repositioning the several elements during the assembly and welding process. Critical welds are spaced from the high stress areas of the secured elements.
