Abstract: A strut member to be secured to the floor structure includes a top skirt-contacting portion for the aerodynamic skirt panel to be secured thereto, a lower skirt-contacting portion for the aerodynamic skirt panel to be secured thereto distant from the top skirt-contact portion, and a strut portion connecting the top skirt-contact portion to the lower skirt-contacting portion. The strut member provides a clearance in which the skirt panel is free of contact with the strut member between the top skirt-contact portion and the lower skirt-contacting portion. The strut portion is configured to resiliently buckle between a buckled position upon the skirt panel undergoing a force exceeding a threshold value toward the strut member and an original position when no force is applied and when the skirt panel is undergoing a force that is less than the threshold value.

Abstract: There is described a top fairing for a trailer adapted to decrease drag and manage water. The top fairing comprises a surface for guiding air thereover, comprising a leading flange; a leading surface having a leading radius, the leading surface being joined to the leading flange and extending in a rearward direction; and a tailing surface having a tailing radius, the tailing surface in continuity to the leading surface in the rearward direction. The top fairing comprises openings disposed in the leading flange for managing water through the leading flange.

Abstract: An aerodynamic skirt assembly is described therein, the aerodynamic skirt assembly comprising a ribbed skirt panel with at least one rib associated with the ribbed skirt panel to alter mechanical properties of the ribbed skirt panel, wherein the rib is providing a longitudinal stiffness of a thinner ribbed skirt panel that is comparable to a thicker non-ribbed skirt panel while allowing momentarily elastic deformation of the ribbed skirt panel when the ribbed skirt panel is contacting a foreign object while returning automatically to a non-deformed configuration when the ribbed skirt panel is not contacting the foreign object.

Abstract: A skirt securing connector assembly for securing an aerodynamic skirt panel to a trailer is provided, the skirt securing connector assembly comprising an upper attachment portion adapted to secure the skirt securing connector assembly to the trailer, a lower attachment portion adapted to secure a lower portion of the aerodynamic skirt panel and a strut member connected, at a first end thereof, to the upper portion of the skirt securing connector assembly and connected, at a second end thereof, to the lower portion of the skirt securing connector assembly, the strut member including a longitudinal axis between the first end and the second end, the strut member including a concave portion extending along the longitudinal axis, the concave portion increasing an inertia moment of the strut member to sustain a force applied by air routing on the aerodynamic skirt.

Abstract: There is provided a method of securing a strut portion to an I-beam of a vehicle, the securing mechanism comprising a pair of opposed clamps, each including a gripping portion, a securing portion, an abutting portion and a fastener adapted to apply tension on the clamps toward each other for moving the clamps toward each other and compress the strut portion to the I-beam.

Abstract: A skirt securing connector assembly for securing an aerodynamic skirt panel to a trailer is provided, the skirt securing connector assembly comprising an upper attachment portion adapted to secure the skirt securing connector assembly to the trailer, a lower attachment portion adapted to secure a lower portion of the aerodynamic skirt panel and a strut member connected, at a first end thereof, to the upper portion of the skirt securing connector assembly and connected, at a second end thereof, to the lower portion of the skirt securing connector assembly, the strut member including a longitudinal axis between the first end and the second end, the strut member including a concave portion extending along the longitudinal axis, the concave portion increasing an inertia moment of the strut member to sustain a force applied by air routing on the aerodynamic skirt.

Abstract: This invention relates to an actuated aerodynamic air drag reducing apparatus for reducing the air drag of a vehicle, the actuated aerodynamic air drag reducing apparatus being adapted to move between an expanded configuration and a retracted configuration by an actuator on a basis of a signal associated to the behavior of the vehicle. The actuator being connected to a slider selectively connected to a pair of pivotable elongated members for being used between a plurality of configurations.

Abstract: This invention relates to a retractable aerodynamic air drag reducing apparatus for reducing the air drag of a vehicle, the retractable aerodynamic air drag reducing apparatus being adapted to move between an expanded configuration and a retracted configuration on a basis of a signal from the vehicle.
