    The invention relates to an aerodynamic hubcap filtering a wheel of a vehicle, in particular an automobile.
    [0002] In order to avoid, on the one hand, the dissipation of particles from the brake pads in the ambient air and, on the other hand, the dirt on the wheels of the vehicles caused by these same particles, it is known to integrate dust filters near the brake pads.
    It is further known from US 2015/0091367 a brake particle filter attached to the rim of a wheel of a vehicle. This filter comprises a filter grid fixed inside the corresponding wheel of the vehicle.
    However, this particulate filter is not suitable for optimizing the collection of braking particles. A portion of these particles is therefore likely to be disseminated in the atmosphere and / or dirty the corresponding wheel of the vehicle.
    The present invention aims to overcome the above disadvantages of the prior art.
    To achieve this object, the invention relates to an aerodynamic wheel cap of a wheel of a vehicle, in particular a motor vehicle, the wheel having a cylindrical rim and a wheel disk having ventilation orifices, characterized in that embellisher comprises an inner portion formed by a turbine fixed coaxially in the rim vis-à-vis the wheel disk to deflect the lateral air flow to the outside of the wheel through radial perforations defined by the blades of the turbine during the driving in rotation of the wheel, an outer portion fixed coaxially in the rim and comprising radial openings defined at least by branches arranged radially between a central portion and a peripheral edge of this outer portion to allow the air flow having passed through the radial perforations of the turbine out of the wheel through the radial openings of the outer part during its training e n rotation, the hubcap further comprising at least one filter disposed coaxially between the inner and outer parts for filtering the particles in suspension in the air flow passing through the wheel during its rotational drive.
    In another feature, the inner portion is fixed by a central portion thereof to the wheel disc.
    In another feature, the outer portion is formed by a turbine identical to the turbine forming the inner portion and fixed to the wheel disk, and the radial branches are formed by the blades of the outer portion.
    In another feature, the radial branches of the outer portion define a plurality of distinct sectors regularly spaced around the central portion of the outer portion and in that each sector comprises therein blades for channeling the flow of air coming out of the wheel through the radial apertures formed between the blades and the radial branches of each concentric sector.
    In another feature, the filter is annular and has a diameter to cover the inner portion.
    The invention also relates to a vehicle wheel, in particular an automobile wheel, comprising a filtering aerodynamic trim as described above.
    The invention also relates to a vehicle, in particular an automobile, each of whose wheels is as described above.
    The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying drawings given solely by way of example illustrating two Embodiments of the invention and in which: - Figure 1 shows an exploded perspective view of a filter aerodynamic embellisher according to a first embodiment; - Figure 2 shows a perspective view of the hubcap of Figure 1 mounted on a wheel; - Figure 3 shows a front view of a second embodiment of the invention of a filter aerodynamic wheel cover mounted on a wheel.
    [0014] With reference to FIGS. 1 to 3, reference numeral 1 denotes a wheel that may comprise a tire to form a wheel / tire assembly of a vehicle, in particular an automobile.
    The wheel 1 of the vehicle consists, in a conventional manner, of a rim 2 and a central wheel disc 3. The rim 2 is the one or two-section profiled circle, which is fixed perpendicularly to the disc of the wheel. wheel 3. The wheel disk 3 is perforated to reduce its weight and create, during the operation of the vehicle (illustrated by the arrow R in FIGS. 2 and 3), an axial air flow for cooling the brakes: the disk of wheel 3 comprises ventilation holes 4 formed between branches 5, which are arranged radially between the central portion of the wheel 1 and the peripheral edge of the rim 2.
    According to the invention, the wheel also comprises a filtering aerodynamic hubcap 6 comprising an inner portion 7 formed by a turbine. This turbine 7 is fixed in the rim 2 coaxially vis-à-vis the wheel disk 3. Preferably, the turbine 7 is fixed by a central portion 8 thereof to the wheel disk 3 using wheel nuts 18, passing through orifices 19 provided for this purpose in the central portion 8 of the turbine 7. The blades 9 of the turbine, extending radially from the center of the turbine 8 towards its outer peripheral edge, are inclined by relative to the general plane of the wheel I, so as to deflect the lateral air flow and amplify the axial air flow directed towards the outside of the wheel 1 during its driving in rotation, through radial perforations 10 defined between the blades 9 of the turbine 7.
    Preferably, the turbine 7 forming the inner part of the hubcap 6 is made of plastic by injection molding.
    The aerodynamic filter cap 6 also includes an outer portion 11 coaxially fixed in the rim 2. In order to allow the axial air flow, amplified by the inner portion 7 of the hubcap 6 when the driving in rotation of the corresponding wheel 1, out of this wheel, the outer portion 11 also comprises radial openings 15, 15a defined at least by radial branches 14, 14a whose structures will be specified below according to two embodiments of the invention. These structures, in addition to allowing the flow of air out of the wheel 1, channels it into the radial openings 15, 15a of the outer portion 11. The outer portion 11 is fixed by a central portion 12 thereof to wheel disc 3 using the wheel nuts 18, passing through orifices 19 provided for this purpose in the central portion 12 of the outer portion II.
    In a first embodiment of the invention shown in Figures 1 and 2, the outer portion 11 is formed by a turbine identical to the turbine forming the inner portion 7. The turbine of the outer portion 11 is attached to the disk wheel 3 via the wheel nuts 18 passing through the orifices 19 of the turbine of the outer portion 11, and the radial apertures 15 are defined by the blades 14 of the turbine 11 extending radially from the center 12 of the turbine towards its edge external device. These blades 14 are inclined relative to the general plane of the wheel 1, so as to direct the axial air flow to the outside of the wheel 1 during its driving in rotation, through the radial perforations 15 defined by the blades 14 of the turbine of the outer part 11.
    In a second embodiment of the invention shown in Figure 3, the radial openings 15 of the outer portion 11 are defined by branches 14 arranged radially between a central portion 12 and an outer peripheral edge of the outer portion 11. These radial branches 14a define several distinct sectors 13 regularly spaced around the central portion 12 of the outer portion 11. For example, five sectors 13 are shown in Figure 3.
    In addition, each sector 13 comprises in the latter blades 16 for channeling the axial air flow out of the wheel 1 through the radial openings 15a formed between the blades 16 and the radial branches 14a of each sector 13 as an example, three blades 16 per sector 13 are shown in FIG. 3.
    In order to channel the axial air flow, the blades 16 of the outer portion 11 may be profiled in "aircraft wing". Preferably, the "wing" profile of the blades 16 is a "CLARK Y" type profile, of relatively simple shape, very effective on a small scale. The profile "CLARK Y" is a particular aerodynamic profile, very widely used in aeronautical construction and model making. In addition, the blades are inclined relative to the general plane of the hubcap 6, that is to say relative to the general plane of the wheel 1.
    Referring again to Figures 1 to 3, the aerodynamic filter cap 6 also comprises at least one filter 17 coaxially disposed between the inner and outer portions 7 and 11 of the hubcap 6. In the embodiments shown in the figures, a single filter 17 is installed. This filter is preferably made of foam material, such as the air filters of internal combustion engines. As shown in the figures, the filter 17 is annular and is sandwiched between the inner 7 and outer 11 parts of the hubcap 6. In addition, it has a substantially identical diameter to the wheel disk 3 so as to cover the portion internal 7 of the hubcap 6.
    The aerodynamic filter cap 6 according to the invention, by the presence of at least one foam filter 17, allows to rid the air flow through the corresponding wheel 1 of the braking particles in suspension, thus avoiding the dirt on the hubcap 6 and wheel 1 and the release of these particles into the atmosphere. In addition, by the presence of the aerodynamic inner and outer parts 7, the lateral air flow is deflected and channeled in the wheel 1 outwardly to emerge from the latter, allowing not only to promote the cooling of the brakes, but especially to optimize the trapping in the filter 17 of the braking particles carried in the air flow passing through the wheel 1.
    The configuration as described is not limited to the embodiment described above and shown in the figures. It has been given only as a non-limiting example. Multiple modifications can be made without departing from the scope of the invention. In particular, one could imagine a conventional fastening system of the hubcap 6 on the edge of the rim 2 of the wheel 1, if the drawing of the outer peripheral edges of the inner 7 and outer 11 respectively allows it. For example and in a nonlimiting manner, a conventional fastening system comprises a plurality of fastening tabs secured to the outer peripheral edges respectively of the inner and outer portions 7 and 11 of the trim and regularly spaced, these tabs being intended to be clipped on the edge of the rim to allow the embedding of the hubcap in the rim 2. One could also imagine a hubcap 6 whose inner portion 7 is identical to the outer portion 11 according to the second embodiment. Finally, the hubcap 6 may comprise several coaxially superimposed filters 17 arranged between the inner and outer portions 7 and 7 of the hubcap 6 according to the invention.
