Specific implementation mode
The purpose of the present invention is in particular, in that provide a kind of aerodynamics wheel hub for being assemblied on the wheel RV of vehicle
Cover EA.
Hereinafter, as non-limiting example, it is believed that vehicle is motor type.The vehicle is, for example, car.But
It is the vehicle the present invention is not limited to the type.The present invention is in fact related to including any of at least one wheel with wheel hub cover
Vehicle.Therefore, the present invention refers at least to land vehicle.
In Fig. 1 to Fig. 5, direction X is known as longitudinal direction, because the direction is parallel to the longitudinal direction of vehicle, direction Y claims
For horizontal direction, because the direction is parallel to the horizontal direction of vehicle, and direction Z is known as vertical direction, because the direction is flat
Row is in the vertical direction of vehicle.Therefore longitudinal direction X is perpendicular to transverse direction Y, and vertical direction Z is transversely to the machine direction direction X
And transverse direction Y.
Fig. 1 and Fig. 2 diagrammatically illustrates the wheel RV of vehicle respectively without and with air force according to the present invention
Learn the example of wheel hub cover EA.As shown, wheel RV include general cylindrical wheel rim JR, be equipped with radial aperture AR and
With the wheel rim JR disc VR being fixedly connected and the outer surface for being placed on disc VR front (so that (almost) is completely hidden
Hide disc VR) and the aerodynamics wheel hub cover EA that is for example fixedly connected with wheel rim JR.
X, transverse direction Y and vertical direction Z extend wheel rim JR along the longitudinal direction.The wheel rim is for example formed from steel.
Disc VR is for example made in steel or aluminum.The disc includes the periphery being preferably welded on the inner surface of wheel rim JR
Edge.It is noted that on Fig. 1 and Fig. 2 in the non-limiting example shown, disc VR include for allow air by 16
A radial aperture AR.But the wheel rim may include any amount of radial aperture AR more than or equal to two.

Ground is connected.The aerodynamics wheel hub cover can be made of metal or plastic material (such as polyamide).
In addition, as shown on Fig. 2 and Fig. 3, it is somebody's turn to do (aerodynamics) wheel hub cover EA and includes central part PC, surrounds central part
The periphery edge BP of point PC and extends between central part PC and periphery edge BP and (and be attached at the central part
Between the periphery edge) blade PE.
These blades PE is separated two-by-two by air duct PA, and with can be by lateral air stream from (wheel RV's)
External direction (disc VR's) radial aperture AR transfers or the on the contrary profile of (external from radial aperture AR directions) transfer.Air
Therefore it is shifted in the air duct PA between being limited to blade PE.
Each of central part PC and periphery edge BP be shaped as defining air is guided towards radial aperture AR it is inclined
To device DA, and it therefore can limit turbulent flow.
For example, the profile of blade PE can be the profile of aircraft wing.Under the non-limiting situation, which for example can
Enough it is the referred to as profile of NACA.Therefore, which is more precisely, for example, the profile for being known as " Clark Y " or " Joukovski ".
It is noted that the blade PE with aircraft wing profile includes the front coupled by " lower surface " and " upper surface "
There is overvoltage below the lower surface, described in edge (bord d ' attaque) BA and back edge (bord de fuite) BF
There are negative pressure (sous-pression) above upper surface.The air to be shifted arrives first at leading edge BA.Moreover, this blade
PE has the theoretical thrust axis across its all theoretical thrust center.
In the case of wheel RV, in example as shown herein, when the lower surface of the blade is oriented towards spoke
When plate VR, each blade PE shifts lateral air stream from (wheel RV's) is external towards (disc VR's) radial aperture AR.Cause
This is in sucking pattern.It is noted that in a variant which is not illustrated, each blade PE can have the following table being oriented outside
Face, in this case, air stream is from (disc VR's) radial aperture AR towards (wheel RV's) flows outside.Therefore in blowout
Pattern.
It is noted that on Fig. 2 and Fig. 3 in the non-limiting example shown, the quantity etc. for the blade PE that wheel hub cover EA includes
Yu Shiliu.Therefore the quantity of radial aperture AR of the quantity equal to disc VR.Therefore, each blade PE and corresponding radial aperture
AR is associated.But this is not enforceable.In fact, the desirable any value more than or equal to two of the quantity of blade PE.
