Filed:

May 6, 2010

Appl. No.:

12/775095

Inventors:

Michael Lorenzo Henderon - Piedmont SC, US
Stephen Alfred Wulff - Simpsonville SC, US

Assignee:

SmartTruckSystems, LLC - Greenville SC

International Classification:

B62D 35/00

US Classification:

2961804, 293117

Abstract:

An apparatus for reducing the drag of a trailer is provided. The apparatus can further include a pair of fairings configured to be positioned on opposite sides of a trailer in front of wheels on the bottom of a trailer, a pair of fairings configured to be positioned on opposite sides of a trailer behind the wheels on the bottom of a trailer, with both pairs of fairings placed and shaped to direct the air smoothly around the wheels and tires and through the center of the trailer. The apparatus can also include a ramp in front of the suspension components, aerodynamically shaped wings on the axles, and a rear diffuser, such components configured to direct air smoothly between the trailer suspension and the ground. The directed high energy air from the apparatus results in a reduced trailer base drag.

Assignee:

SmartTruck Systems, LLC - Greenville SC

International Classification:

G02B 7/182

US Classification:

359872

Abstract:

In accordance with certain embodiments of the present disclosure, a mirror assembly for a vehicle is described. The mirror assembly includes a first curved wall, a second curved wall, a bottom portion, and a top portion. The first curved wall and second curved wall each extend from the bottom portion to the top portion and are joined to one another along a respective first side of each of the first curved wall and the second curved wall. The first curved wall, second curved wall, bottom portion, and top portion define an area comprising a reflecting surface. Each respective second side of each of the first curved wall and the second curved wall extends beyond the plane defined by the area and assists in a reduction in drag when fluid flow contacts the mirror assembly.

International Classification:

B62D 35/00
B62D 35/02

US Classification:

2961804, 2961815

Abstract:

In accordance with certain embodiments of the present disclosure, a vehicle trailer is provided. The vehicle trailer includes a roof and a floor separated from each other by a pair of opposing walls that extend along the length of the floor. The roof, floor, and walls define a space accessible by a trailer door with each of the walls having a front edge and a rear edge and having a height that extends from the floor to the roof. The height is substantially the same along at least a portion of the length of the walls. The vehicle trailer further includes a pair of side wall fairings having a leading edge and trailing edge. Each side wall fairing is positioned on a different wall from the other adjacent to the rear edges of each of the walls such that the leading edge of each side wall fairing contacts the wall and the trailing edge of each side wall fairing does not contact the wall. Each side wall fairing has an upward incline and downward incline. The side wall fairings can be utilized with one or more other components that are described herein.

Inventors:

- Greenville SC, US
Stephen Alfred Wulff - Simpsonville SC, US

International Classification:

B62D 35/00

Abstract:

A nose fairing for a cargo enclosure may generally include a nose body configured to extend outwardly from a front wall of the enclosure. The nose body may include an upper nose wall, a lower nose wall and a leading edge region extending between the upper and lower nose walls. The upper nose wall may include a concave region that terminates at the leading edge region such that the nose fairing transitions directly from the concave region of the upper nose wall to the leading edge region. The lower nose wall may include a convex region that terminates at the leading edge region such that the nose fairing transitions directly from the convex region of the lower nose wall to the leading edge region. The leading edge region may define a radius of curvature that differs from a radius of curvature of the convex region of the lower nose wall.
