An air resistance reducing assembly for use in tandemly coupled vehicles, one of the vehicles being a hauling, another of the vehicles being a trailing vehicle, the trailing vehicle including a front wall and a top panel, an the air deflector having leading and trailing edges disposed transversely of the direction of forward movement of the vehicles and carried at an upper leading end portion of the trailing vehicle, the deflector overlying the surface of upper leading end portion while remaining disposed respectively behind and below the plane of the front wall and the top panel, the air deflector being formed and disposed to deflect air to pass therebeneath adjacent the surface of the upper leading end portion and along the top of the trailing vehicle.

1. An air resistance assembly for use in combination with tandemly coupled vehicles, one of said vehicles being a hauling vehicle, another of said vehicles being a trailing vehicle, said hauling vehicle and said trailing vehicle each normally having a drag following therebehind serving to act upon and tend to retard the vehicle movement through air, said drag acting parallel and opposite to the direction of movement of said vehicles, said trailing vehicle including a front wall and a top panel, air deflector means having leading and trailing edges disposed transversely of the direction of forward movement of said vehicles and carried at an upper leading end portion of said trailing vehicle, said deflector overlying the surface of said upper leading end portion while remaining disposed respectively behind and below the plane of said front wall and said top panel, said air deflector means being formed and disposed to deflect air to pass therebeneath adjacent the surface of said upper leading end portion and along the top of said trailing vehicle, the last named said means serving to evacuate sufficient air from behind the hauling vehicle to substantially reduce said drag acting thereon. 2. An air resistance reducing assembly for use in combination with tandemly coupled vehicles, one of said vehicles being a hauling vehicle, another of said vehicles being a trailing vehicle, said hauling vehicle and said trailing vehicle normally having a drag following therebehind serving to act upon and tend to retard the vehicle movement through air, said drag acting parallel and opposite to the direction of movement of said vehicles, said trailing vehicle including a front wall and a top panel, air deflector means disposed transversely of the direction of forward movement of said vehicles and carried at an upper leading end portion of said trailing vehicle, said upper leading end portion being sufficiently relieved to dispose said air deflector means behind the plane of said front wall and beneath the plane of said top panel, said air deflector means being formed and disposed to deflect and pass air therebeneath along said upper leading end portion and along the top panel of said trailing vehicle, the last named said means serving to evacuate sufficient air from behind the hauling vehicle to substantially reduce said drag acting thereon. 3. An air resistance reducing assembly according to claim 2 in which said last named means comprises an air deflection panel formed to include an arcuate shape as viewed in end elevation cross-section thereof, said upper leading end portion of said trailing vehicle being formed with an arcuately curved surface beneath said top panel, and means supporting said air deflection panel in spaced relation from said end portion, the leading edge of said deflection panel being spaced farther from said end portion than the spacing between the trailing edge thereof and said end portion to provide a region of convergent air flow from both above and below said air deflection panel for withdrawing air from behind the hauling vehicle and to hold the air flow closely adjacent to the top surfaces of said trailing vehicle. 4. A van type trailer of a type adapted to be towed by a hauling vehicle normally having a drag following therebehind and serving to act upon and tend to retard the vehicle movement, said drag acting parallel and opposite to the direction of movement of said vehicle, said trailer having front and top walls, and an upper leading front end portion formed with an upwardly and rearwardly curved surface, an air deflection panel carried by said front end portion and lying substantially entirely behind the plane of said front wall, said panel having an arcuate shape as viewed in end elevation cross-section thereof, means supporting said panel in spaced relation from said surface and transversely of the trailer, the leading edge of said panel being spaced further from said end portion than the spacing between the trailing edge thereof and said end portion to provide a region of convergent air flow from both above and below said panel for withdrawing air from behind the hauling vehicle to relieve the drag following said hauling vehicle.
