Trailer skirt panel

ActiveUS7578541B2Reducing aerodynamic drag on road vehiclesIncrease air flowVehicle seatsWindowsAerodynamic dragEngineering
A skirt panel is provided herein for interconnection to another abutted similar skirt panel for attachment beneath a lower, outer longitudinally-extending edge of a trailer including a rear wheel assembly of a tractor-trailer rig, thereby to provide a continuous fairing extending downwardly from the trailer. The skirt panel includes a monolithic, generally-rectangular composite reinforced thermoplastic structure, having vertical lateral side edges configured and arranged for connection to associated vertical lateral side edges of abutting similar skirt panels. This provides a longitudinally-extending fairing for extending contiguously on each side of the trailer, a front face of the thermoplastic structure being provided with a plurality of longitudinally-extending, vertically-spaced-apart arcuate protrusions. The outer face of the thermoplastic panel preferably also is provided with dimples. The reinforcing comprising a panel secured to an inner face of the skirt panel and is provided with laterally-extending means whereby abutting skirt panels are secured to one another; whereby, when said fairing is secured to a lower portion of said trailer, the fairing extends downwardly from the trailer to from 60% to 80% of the distance to the road, so that a portion of any impinging air is directed laterally around the wheels of the rear wheel bogeys to reduce the aerodynamic drag of the trailer and of the wheel assembly.
