Deployable aerodynamic device for rear of a cargo body

This invention provides aerodynamic structures for the rear of a cargo body that move between a deployed position and a retracted position. The aerodynamic structures are typically three-sided, with a top panel and opposing side panels that form a partial cavity at the rear of the body. The panels e...

description	This invention provides aerodynamic structures for the rear of a cargo body that move between a deployed position and a retracted position. The aerodynamic structures are typically three-sided, with a top panel and opposing side panels that form a partial cavity at the rear of the body. The panels employ tensioned flexible (e.g. fabric) panels or rigid/semi-rigid panels that are stowed, rolled, or folded in a retracted position against the rear of the door frame (for flexible panels) of the cargo body, or along the sides of the cargo body (for rigid/semi-rigid panels). The rigid/semi-rigid panels can be stored within nacelles that protect the panels and improve aerodynamic performance. Various linkages, including rotating rigid members attached to the rear of the body can coordinate movement between a top panel and side panels between deployed and retracted positions and a variety of powered and non-powered actuators can facilitate panel movement.
