A clamp assembly is provided for securing a panel or fairing to an I-beam, and comprises a pair of side blocks and a clamping block, together with a single bolt to secure them in place. Each of the side blocks as an inclined wedge surface, and the T-shaped clamping block has similarly sloped wedge surfaces along the sides of the leg of the T. When a bolt this passed through side legs of the side blocks, and through or under the clamping block, a sliding and wedging action between the inclined and sloped wedge surfaces occurs. Moreover, a clamping action between the top surface of the clamping block and the lower surface of the lower flanges of the I-beam is also induced.

The aerodynamic skirt assembly for attachment to a trailer may comprise a side skirt fairing, a transition, and a vented skirt fairing. The transition may be located aft of the side skirt fairing and forward of the vented skirt fairing. The vented skirt fairing may be located aft of the transition. The vented skirt fairing may comprise at least one longitudinal vent configured to allow air to flow therethrough. The vented skirt fairing may extend outwardly of the side of the trailer frame to accommodate the wheels. One or more mounting brackets may be used to couple the elongated skirt panel, the transition, and the vented skirt fairing to one or more transverse structural support members. A rear exhaust fairing may be located aft of the vented skirt fairing and coupled to one or more transverse structural support members.

A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer. The strut assembly may comprise a mounting plate, a strut body, and a spring. The spring may be substantially rectangular. The mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls. The strut body rotatably may be coupled to the pair of spaced apart sidewalls on the mounting bracket. The spring may be coupled to an upper surface of the strut body and configured to contact an underside of the mounting plate of the mounting bracket to resist inward deflection from an external force applied to the strut body.

A side skirt assembly for attachment to a trailer of a tractor-trailer, particularly to a trailer frame comprising transverse structural support members extending between sides of the trailer. The side skirt assembly comprises an elongated skirt panel, an elongated support and one or more skirt support members. The side skirt assemble comprises an inner surface and an outer surface. The elongated support is coupled to the elongated skirt panel on the inner surface thereof proximate an upper edge of the elongated skirt panel and extends at least a portion of the length of the elongated skirt panel. The more skirt support members couple the elongated skirt panel to a corresponding one or more or of the transverse structural support members.

A clamp assembly is provided for securing a panel or fairing to an I-beam, and comprises a pair of side blocks and a clamping block, together with a single bolt to secure them in place. Each of the side blocks as an inclined wedge surface, and the T-shaped clamping block has similarly sloped wedge surfaces along the sides of the leg of the T. When a bolt this passed through side legs of the side blocks, and through or under the clamping block, a sliding and wedging action between the inclined and sloped wedge surfaces occurs. Moreover, a clamping action between the top surface of the clamping block and the lower surface of the lower flanges of the I-beam is also induced.
