The conditioning of cross winds by providing up to four separate groups of segmented panels being the main segmented panels of the segmented air deflector, opposing segmented side pivotal panels, opposing segmented upper side pivotal panels and opposing segmented lower side pivotal panels. Various i
The conditioning of cross winds by providing up to four separate groups of segmented panels being the main segmented panels of the segmented air deflector, opposing segmented side pivotal panels, opposing segmented upper side pivotal panels and opposing segmented lower side pivotal panels. Various implementations of application of these groups provide versatility for varying conditions and vehicle configurations. A method of measuring for cross wind conditions and selective engaging the various deployed segmented panels is disclosed. The use of wing members either fixed or variably mounted on or about the various panels to condition, and therefore better control wind flow, is taught.

Cross wind conditioning means to provide for a selective redirection of air flow to reduce the effect of cross winds on a tractor, the tractor adaptable to tow a trailer, the tractor and the trailer forming a tractor trailer combination, the tractor having a roof area, a direction of forward travel, a left and right directional orientation corresponding to a position facing forward in the direction of forward travel of the tractor, an imaginary center line extending through the tractor corresponding to the direction of forward travel, a tractor housing, a left rear vertically oriented trailing edge of the tractor housing, a right rear vertically oriented trailing edge of the tractor housing, the trailer having a forward face, the forward face having a perimeter formed by an upper edge, a right side edge, a left side edge and a lower edge, the right side edge and the left side edge both corresponding to a directional orientation facing forward in the direction of forward travel of the tractor, the cross wind conditioning means comprising: a) a segmented air deflector attachable to the roof area of the tractor, the segmented air deflector having a directional orientation following attachment, the directional orientation including left, right, forward and rear and corresponding to the directional orientation of the tractor, the segmented air deflector having a left side, a right side, a forward edge, a rear upper edge, a left rear vertically oriented trailing edge and a right rear vertically oriented trailing edge all corresponding to the directional orientation of the segmented air deflector following attachment, the segmented air deflector comprising: 1) a frame system; 2) a plurality of segmented panels attached to the frame system, each segmented panel having a plurality of planar outer surfaces with a linear juncture between adjoining surfaces, the segmented air deflector having alternating positions being a closed position and an open position, the closed position providing characteristics to stream line air flow around the trailer during motion of the tractor trailer combination to reduce drag, the closed position having a continuous segmented surface area formed by the plurality of segmented panels, the open position placing at least one of the segmented panels in a moved position to cause redirection of the air flow during motion of the tractor trailer combination to cause the air flow to impinge the forward face of the trailer to exert a braking force on the tractor trailer combination; 3) a drive means to provide for a selective movement of at least one of the segmented panels to transfer the segmented air deflector between the alternating positions; b) a left side panel mounted on the left side of the segmented air deflector and having a substantially vertical orientation between the roof area of the tractor and the continuous segmented surface area of the segmented air deflector while the segmented air deflector is in the closed position, the left side panel having a left portal; c) a right side panel mounted on the right side of the segmented air deflector and having a substantially vertical orientation between the roof area of the tractor and the continuous segmented surface area of the segmented air deflector while the segmented air deflector is in the closed position, the right side panel having a right portal; d) a left side pivotal panel pivotally mounted on the left side panel and substantially filling the left portal, the left side pivotal panel having alternating positions, the alternating positions being a closed position and an open position, the closed position prohibiting entry of air flow through the left portal, the open position allowing entry of air flow through the left portal; e) a right side pivotal panel pivotally mounted on the right side panel and substantially filling the right portal, the right side pivotal panel having alternating positions, the alternating positions being a closed position and an open position, the closed position prohibiting entry of air flow through the right portal, the open position allowing entry of air flow through the right portal; f) a first left drive means to provide for a selective transfer of the left side pivotal panel between the alternating positions; g) a first right drive means to provide for a selective transfer of the right side pivotal panel between the alternating positions; h) a first left side measuring means to provide for determining a predetermined presence of cross wind conditions on the left side of the tractor trailer combination; i) a first right side measuring means to provide for determining a predetermined presence of cross wind conditions on the right side of the tractor trailer combination; j) a first left control means to provide for continually testing the first left side measuring means to determine a change in status, the change in status being alternatively between a measurement below the predetermined presence of cross wind conditions and a measurement above the predetermined presence of cross wind conditions, the change in status causing activation of the first left drive means to transfer the left side pivotal panel between the alternating positions; k) a first right control means to provide for continually testing the first right side measuring means to determine a change in status, the change in status being alternatively between a measurement below the predetermined presence of cross wind conditions and a measurement above the predetermined presence of cross wind conditions, the change in status causing activation of the first right drive means to transfer the right side pivotal panel between the alternating positions; whereby the respective first measuring means would signal a change in status of cross wind conditions and the respective first control means would cause the respective first drive means to cause the respective side pivotal panels to be placed in one of the alternating position closed when cross wind conditions are not present on that respective side and open when cross wind conditions are present on that respective side.
