ABSTRACT:
A combination air fairing and auxiliary braking device (10) for use in connection with trucks, vans, trailers, or the like vehicles. The device (10) includes an air fairing structure (14) which serves to produce a preselected outline and reduce the drag resulting from air resistance during motion of the vehicle (12). A plurality of relief doors (16) are carried by the air fairing structure (14), and are operable between closed and opened positions such that the drag is reduced when the relief doors (16) are closed, and the drag is increased when the relief doors (16) are opened. A system (40) is provided for selectively opening and closing the relief doors (16) at preselected time. For example, the relief doors (16) are open to increase the drag as a vehicle is slowing down to provide auxiliary braking forces.
