  • Aerodynamic underbody device for trailer (and box-truck)
    Patent number: 6837536
    Abstract: A belly pan, or membrane of rigid yet flexible material is of elongated shaped outline to be mounted along the bottom of tractor-trailer to improve the aerodynamic performance. The belly pan is provided with a tapered front portion to be attached to the frontal portion of the trailer to the approximate location of the truck hitch. The belly pan extends rearwardly, under the trailer, between the rear wheels in a rectangular portion and the rearward edge is affixed to the ICC bumper of the trailer. An aerodynamic shaped deflector is attached to the frontal portion of the landing gear of the trailer and attaches to the belly pan for reducing drag between the underside of the trailer and the support beams of the landing gear. A similar aerodynamic shaped deflector is attached to the frontal portion of the ICC bumper and attached to the belly pan for reducing drag between the underside of the trailer and the beams of the ICC bumper.
