Aerodynamic trucking systems
An aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer. The aerodynamic fairing assembly may comprise a front skirt fairing and a rear skirt comprising a transition. The transition may extend outwardly of the side skirt fairing at a distance from the centerline of the trailer. The side skirt faring and rear skirt fairing are coupled to the trailer by one or more struts.
1. An aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a top, bottom, front, rear, a pair of sides, a trailer frame having a centerline, transverse structural support members extending between sides of the trailer defining a trailer envelope, and longitudinal members extending along a length of the trailer, and having at least one rear wheel assembly situated below the trailer frame, the aerodynamic fairing assembly comprising:
a side skirt fairing comprising an inner surface and an outer surface;
a rear skirt fairing located aft of the side skirt fairing and comprising a transition extending outwardly of a side of the trailer envelope at a distance from the centerline of the trailer; and
one or more struts configured to couple the side skirt fairing and the transition to one or more of the transverse structural support members.
2. The aerodynamic fairing assembly of claim 1 , wherein the struts rotatably couple the side skirt fairing and the rear skirt fairing to one or more or of the transverse structural support members.
3. The aerodynamic fairing assembly of claim 1 , wherein the side skirt fairing is substantially straight and runs parallel to the centerline of the trailer.
4. The aerodynamic fairing assembly of claim 1 , wherein the side skirt fairing is substantially straight and is angled outwardly from the centerline of the trailer along the longitudinal axis from a front edge to a rear edge of the side skirt.
5. The aerodynamic fairing assembly of claim 1 , wherein the side skirt fairing is generally planar and formed by a plurality of sections.
6. The aerodynamic fairing assembly of claim 1 , wherein the aerodynamic fairing assembly is constructed from an injection molded material.
7. The aerodynamic fairing assembly of claim 6 , wherein the injection molded material comprises an injection molded mixture of polycarbonate and ABS plastic.
8. The aerodynamic fairing assembly of claim 1 , further comprising a front fairing located forward of the side skirt fairing.
9. The aerodynamic fairing assembly of claim 1 , wherein the transition is angled outwardly with respect to the centerline of the trailer to cause misdirection of the air prior to reaching the rear of the trailer.
10. The aerodynamic fairing assembly of claim 1 , further comprising:
a forward panel coupled to the sides of the trailer adjacent the rear of the trailer,
a transition located aft of the forward panel, and
a rear panel located aft of the transition and coupled to the rear door frame, wherein the transition is angled outwardly to cause misdirection of the air prior to reaching the rear door frame.
11. An aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a top, bottom, front, rear, a pair of sides, a rear door frame, and a trailer frame having a centerline, transverse structural support members extending between sides of the trailer defining a trailer envelope, and longitudinal members extending along a length of the trailer, the aerodynamic fairing assembly comprising:
a side skirt fairing comprising an inner surface and an outer surface;
a rear skirt fairing comprising a transition located aft of the side skirt fairing and extending outwardly of the side of the trailer envelope;
one or more struts configured to couple the side skirt fairing and the rear skirt fairing to one or more or of the transverse structural support members; and
an exit skirt fairing comprising:
a forward panel coupled to the side of the trailer adjacent the rear of the trailer,
a transition located aft of the forward panel, and
a rear panel located aft of the transition and coupled to the rear door frame, wherein the transition is angled outwardly to cause misdirection of the air prior to reaching the rear door frame.
12. The aerodynamic fairing assembly of claim 11 , further comprising a front fairing located forward of the side skirt fairing.
13. The aerodynamic fairing assembly of claim 12 , wherein the one or more struts are configured to couple the front skirt fairing to one or more or of the transverse structural support members.
14. The aerodynamic fairing assembly of claim 11 , wherein each side skirt fairing is substantially straight and is angled outwardly from the centerline of the trailer along a longitudinal axis from a front edge to a rear edge of the side skirt.
15. The aerodynamic fairing assembly of claim 11 , wherein the side skirt fairing is generally planar and formed by a plurality of sections.
16. The aerodynamic fairing assembly of claim 11 , wherein the aerodynamic fairing assembly is constructed from an injection molded material.
