ABSTRACT:
An apparatus to control the air as it passes a tractor trailer combination as they travel along a road. This device will allow for variable redirection of the air flow to allow various desired effects to be met. The flow of air is streamlined to minimize the effects of cross winds. Air pressure responsive plates are provided at the ends of laterally extending gates mounted on tractor trailer combinations to minimize the effects of sudden drafts of air that sweep across roadways. A method of redirecting the air flow for ventilation and cooling purposes for both refrigeration units and brake components is provided. Air ducts are provided for the transport of the redirected air for the ventilation and cooling of the brake components. Additionally the air flow can be directed to impact with the exterior vertical front face of the trailer section to create an air drag which will create resistance to forward travel. Deflection protection is provide for the vehicle as a whole and for the refrigeration unit specifically.
