An aerodynamic drag reduction system includes a side panel configured to be coupled to a rear swing door to extend generally vertically at least partially along a height of a trailer and a top panel configured to be coupled to the rear swing door to extend generally horizontally at least partially along a width of the trailer. The drag system includes a cable system configured to connect the side and top panels to prevent upward movement of the top panel beyond its generally horizontal position. The cable system includes a first cable with a first end coupled to an inner surface of the side panel, and a second cable and a third cable each with a first end coupled to a bottom surface of the top panel. A second end of each of the first cable, the second cable, and the third cable is coupled together at a juncture.

Aerodynamic rear drag reduction system for a trailer

A nose gap reducer for reducing drag on a vehicle is disclosed. The nose gap reducer may be coupled to a vehicle such as a trailer of a semi-trailer truck for example. The trailer may be positioned between a tractor unit or between another trailer.

Nose gap reducers for trailers

An aerodynamic rear drag reduction system is configured to be coupled to a frame assembly of a trailer including a rear frame and a rear swing door. The drag reduction system includes a top panel configured to be coupled to a top portion of the rear swing door to extend generally horizontally along a top portion of the rear frame of the trailer. The drag reduction system also includes a folding mechanism coupled to the top panel to move the top panel between a fully-deployed position wherein the top panel is configured to extend rearwardly generally away from the rear end of the trailer and a collapsed position wherein the top panel is configured to lie generally adjacent the rear swing door of the trailer. The folding mechanism is configured to be coupled to a door locking mechanism of the trailer.

An aerodynamic rear drag reduction system of the present disclosure is configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door. The drag reduction system includes a side panel configured to be coupled to the rear swing door to extend generally vertically at least partially along a height of the trailer; and a folding mechanism coupled to the side panel. The folding mechanism moves the side panel between (i) a fully-deployed position wherein the side panel is configured to extend generally rearwardly away from the rear end of the trailer and (ii) a fully-stowed position wherein an inner surface of at least a portion of the side panel is configured to lie generally adjacent the rear swing door. The folding mechanism is configured to be coupled to a door locking mechanism of the trailer for movement therefrom.

An aerodynamic rear drag reduction system of the present disclosure is configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door. The drag reduction system includes a top panel configured to be coupled to the rear swing door of the trailer and a hinge configured to couple the top panel to the rear swing door. The hinge includes a planar bracket configured to be coupled to the rear swing door, an L-shaped bracket configured to be coupled to the top panel, and a hinge joint configured to couple together the planar bracket and the L-shaped bracket. The hinge joint is configured to rotate about a pivot axis that is substantially parallel to a top edge of the rear frame of the trailer when the top panel is coupled to the rear swing door.
