     BACKGROUND 
       [0002]    With today&#39;s emphasis on fuel savings and green energies, aerodynamics continue to be a priority of most vehicle design engineers. In accordance therewith, vehicle designs undergo many stringent wind tunnel tests that study the effects of air moving past solid objects. 
         [0003]    Many years ago, wind tunnels were initially used as a means of studying airplanes in flight. Since then, emphasis on fuel efficiencies has prompted use of the wind tunnel in the design of land vehicles as well. The wind tunnel was envisioned as a means of reversing the usual paradigm. Rather than a moving a vehicle through still air, the wind tunnel moves the air past a still vehicle. Moving the air rather than the vehicle enables an engineer or researcher to more effectively study and manage aerodynamic effects. 
         [0004]    In addition to aerodynamic effects, wind-tunnel testing is often applied to land vehicles to determine ways to reduce the power required to move the vehicle on roadways at a given speed. In the study of land vehicles, interaction between the road and the vehicle plays a significant role in performance and results. Thus, this interaction is taken into consideration when interpreting the test results. In actual scenarios, the roadway is moving relative to the vehicle but the air is stationary relative to the roadway. In most wind tunnel tests, air is moving relative to the roadway, while the roadway is stationary relative to the test vehicle. In order to address this phenomenon, some automotive-test wind tunnels employ moving belts under the test vehicle in an effort to approximate real-world conditions. 
         [0005]    Today, aerodynamic hoods, roofs, skirts, etc. are employed to lower wind drag of land vehicles. There exists an ongoing need in the art to continue to develop aerodynamic products and designs that enhance wind drag efficiencies. 
       SUMMARY 
       [0006]    The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements of the innovation or to delineate the scope of the innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later. 
         [0007]    The innovation disclosed and claimed herein, in one aspect thereof, comprises an aerodynamic wheel cover for use on land vehicles. In aspects, the wheel cover can be applied to the front wheels of long-haul trucks in order to enhance aerodynamic effects and reduction of wind drag. The covers can be manufactured of a resilient material which permits the cover to flex when exposed to aerodynamic forces, however, the covers can be suitably rigid so as to refrain from contact with a rotating wheel. 
         [0008]    In one aspect, the wheel cover(s) is fixedly mounted thereby creating an aerodynamic cover that can reduce wind drag. In another aspect of the subject innovation, the wheel cover(s) can turn or redirect with the wheel(s) and steering. For example, the cover can be attached to the wheel such that it turns as the wheel turns. In other aspects, the cover can be attached to the steering linkage to effect tracking of the wheel and steering. 
         [0009]    To the accomplishment of the foregoing and related ends, certain illustrative aspects of the innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the innovation can be employed and the subject innovation is intended to include all such aspects and their equivalents. Other advantages and novel features of the innovation will become apparent from the following detailed description of the innovation when considered in conjunction with the drawings.

     DETAILED DESCRIPTION 
       [0016]    The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the innovation. 
         [0017]    Referring initially to the drawings,  FIG. 1  illustrates an example perspective view of a truck body  100  that employs an aerodynamic wheel cover  102  in accordance with the innovation. In aspects, the wheel cover  102  is applied to, or positioned outside, the front wheels of long-haul trucks in order to enhance aerodynamic effects and reduction of wind drag. It will be appreciated that, on multi-wheel steering vehicles, e.g., four-wheel steering, the articulating wheel cover  102  can be applied to the rear wheels as desired. In operation, covers  102  can be manufactured of a resilient material which permits the cover  102  to flex while being sufficiently rigid so as to withstand aerodynamic forces. It is to be appreciated that most any material, including but not limited to, plastic, aluminum, composite, metal, alloy, resilient material, non-resilient material, or the like can be employed to manufacture the wheel cover  102 . 
         [0018]    As will be shown and described in greater detail below, in aspects, the wheel cover(s)  102  is fixedly mounted thereby creating an aerodynamic cover that can reduce wind drag. In another aspect of the subject innovation, the wheel cover(s)  102  can turn, pivot or redirect (e.g., articulate) in synchronization with the wheel(s) and steering. For example, the cover  102  can be rotatably attached to the wheel such that it turns as the wheel turns. In other words, a rotatable hub can be employed to attach the wheel cover to the wheel (e.g., lugs  408 ). In still other aspects, the cover  102  can be attached to the steering linkage to effect tracking of the wheel and steering. 
         [0019]    Referring now to  FIGS. 2 and 3 , an alternative example of a truck cab  200  having an aerodynamic wheel cover  202  incorporated therein is shown. As described herein, the wheel cover  202  can be integrally molded or attached as appropriate. The attachment can be fixedly or removeably by design. Further, the cover(s)  202  can be attached to the wheel and/or steering so as to effect movement with the wheel and/or steering. 
         [0020]    It is to be understood that wheel cover  202  can be integrally molded into the overall body design of the truck shown in  200 . In aspects, the wheel cover(s)  202  can be fixedly or removeably attached by way of brackets or other frictional attachment means. It is to be understood that most any bracket or attachment means can be used without departing from the features, functions and benefits of the innovation and claims appended hereto. 
         [0021]    Referring now to  FIG. 4 , an example wheel cover assembly  400  is shown in accordance with aspects of the innovation. As illustrated, the cover assembly  400  can include a shield or cover panel  402  that is configured and positioned on a vertical plane consistent with a wheel  404 . In this aspect, the cover portion  402  can be rotatably mounted to the wheel using a fixed connection  406 . In this aspect, the cover can be of circular shape substantially the same (or smaller) size (circumference) of the wheel and/or tire. In other aspects, the cover  402  can be of a half moon or other shape so as to effect or enhance aerodynamic properties of the innovation. 
         [0022]    In an aspect, the panel  402  can be directly mounted (e.g., bolted) to the wheel lugs  408 . In this embodiment, it will be appreciated that it is imperative that the cover  402  be of smaller size in relation to the outer circumference of the tire. In other aspects, adapter plates (not shown) can be employed to fixedly, and rotatably attach the panel to the wheel. It is to be appreciated that most any method of rotatably attaching a panel  402  to a wheel  404  is contemplated and to be included within the scope of this disclosure and claims appended hereto. 
         [0023]    Turning now to  FIG. 5 , an alternative example of a wheel cover assembly  500  is shown in accordance with aspects of the innovation. As illustrated, the assembly  500  can include a panel  502  that is non-rotatably mounted to a wheel  504 . In this aspect, the cover  502  can employ a rotatable adapter or mounting plate  506 . Here, the plate  506  can be attached to a wheel and include bearings or the like that enable the adapter to spin with the wheel  506  while maintaining the position of the panel  502  (e.g., held stationary without spinning) 
         [0024]    It will be appreciated that, because the panel does not rotate in this example, the shape can be consistent with that of  FIGS. 1 ,  2  and  3  herein. Similarly, as indicated by the dashed arrow in  FIG. 5 , the panel  502  can, if desired, be mounted at a height above the tire height. These features, functions and benefits will be appreciated by those skilled in the art. Further, consistent with  FIGS. 5 and 6  (infra), the panel  502  is capable of tracking the direction of the wheel  504  as indicated by the arc-shaped arrow. 
         [0025]    Referring now to  FIG. 6 , an alternative example of a wheel cover assembly  600  is shown in accordance with aspects. Generally, the assembly includes a panel  602  that shields or otherwise covers a wheel  604 . The cover  602  can be attached to steering, linkage, suspension or other components by mechanism (e.g., linkage)  606 . It will be appreciated that most any means of attaching the panel  602  to the steering components can be used without departing from the spirit and/or scope of the innovation as described herein. 
         [0026]    While specific configurations are shown and described in this specification, it will be understood that other aspects can be employed that facilitate the features, functions and benefits of the innovation. For instance, other aerodynamic wheel covers can be employed upon the front wheels of a long haul truck. Similarly, other aspects can include components and connections that enable panels to track or turn with the steering of a vehicle, e.g., long haul truck. These aspects are to be included within the scope of this specification. 
         [0027]    While the aspects described herein are directed to long haul truck applications, it is to be understood that the features, functions and benefits of the innovation can be applied to most any land vehicle without departing from the spirit and scope of this disclosure. Additionally, deflector (or deflector apparatus)  304 , louvers  104  or the like can be employed so as to alleviate forces of air upon the panes, e.g., upon turning. Further, aspects can employ quick disconnects or hinges so as to assist in removal, for example, in maintenance situations. These alternative aspects are to be included within the scope of the innovation and claims appended hereto. 
         [0028]    In summary, what has been described above includes examples of the innovation. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the subject innovation, but one of ordinary skill in the art may recognize that many further combinations and permutations of the innovation are possible. Accordingly, the innovation is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
