Aerodynamic component mounting assembly for tractor trailer

A mounting assembly for coupling an air drag reduction system to a trailer to be transported by an over-the-road tractor, the mounting assembly comprising:

• a frame to be suspended adjacent to an underside of the trailer;
• a receiver supported adjacent to a first end of the frame, wherein the receiver comprises a channel with an aperture that is to receive a portion of a flange of a structural beam of the trailer when installed;
• a fastening mechanism that is pivotally coupled to the frame and is separated by an adjustable distance along the frame from the receiver, the fastening mechanism comprising a camming wheel that is pivotal about an axis of rotation and is positioned to contact another portion of the structural beam and urge the receiver towards the flange, wherein,
• a position of the axis of rotation is adjustable relative to the frame by pivotal adjustment of the fastening mechanism between a first position where the wheel initially makes contact with the another portion of the structural beam and a second position where the wheel is partially compressed against the another portion of the structural beam;
• and
• a locking device that interferes with pivotal adjustment of the fastening mechanism from the second position.
