초록

A frame extension device for the reduction of aerodynamic drag and for improved performance of ground vehicles by increasing the pressure on the base of the vehicle by stabilizing the wake flow. The device is particularly suited for tractor-trailers utilizing a roll-up type rear door in that it does not block any part of the door opening. The device is of sufficient thickness to support the weight of an unloading device.

청구항

What is claimed is: 1. An aerodynamic frame extension device for reducing the aerodynamic drag when attached to a rear door frame of a tractor-trailer, the aft surface of the door frame having a perimeter with a top, bottom and sides that define a door opening, the device comprising: a frame structure comprised of four rigid panels integrally connected to each other, the frame being substantially permanently affixed to the perimeter of the aft surface of the rear door frame; wherein the frame structure has a vertical height equal to at least the vertica...
