초록 ▼

An air inflated bag of inflexible sheet material includes a front portion which is mounted on the body or cab of a vehicle such as a tractor hitched to a semi-trailer. A rear portion of the inflated bag extends between the cab and the trailer body to provide for a smooth non-turbulent flow of air around the cab and to the side and top walls of the trailer body for significantly reducing the aerodynamic drag on the tractor-trailer vehicle. The front portion of the bag is provided with a generally horizontal inlet which is located directly above the front windshield of the cab to direct a portion of the upward flow of air over the cab into the bag and thereby effect dynamic inflation of the bag at a predetermined road speed. The bag may be collapsed to a folded condition adjacent the cab for when the tractor is being driven without a trailer, and a bottom recess is formed within the rear portion of the bag to provide for extending service lines between the cab and the trailer. A low flow of air may be provided through the bag for supplying air to an air conditioning or refrigeration system, and the bag may be made adjustable for accommodating variations in the space between the cab and the trailer.

Apparatus for mounting on the upper portion of a first body of a wheel supported road vehicle to reduce the aerodynamic drag produced by a generally vertical front wall of a second body projecting above the first body, said apparatus comprising an air enclosure member defining an air chamber and including a flexible wall, means for mounting said enclosure member on the upper portion of the first body in a position where said flexible wall projects upwardly and rearwardly over the first body and also in front of and toward the front wall of the second body and is exposed to the flow of air over the first body when the vehicle is moving forwardly along a road, said flexible wall being capable of collapsing inwardly in response to the pressure exerted by the flow of air over the first body, means defining a ram air inlet for said air enclosure member and located above the first body, said air inlet being positioned to receive directly a small portion of the air flowing over the first body for pressurizing said chamber with sufficient pressure to avoid collapsing of said flexible wall and to cause the air enclosure member to streamline the flow of air past the first body and the vertical front wall of the second body, and the forward projected area of said inlet is substantially small relative to the forward projected area of said air enclosure member to minimize aerodynamic drag associated with said air inlet.
