Description
L'invention concerne un dispositif aérodynamique montable sur un véhicule automobile. The invention relates to an aerodynamic device mountable on a motor vehicle.
On sait qu'il est très important d'améliorer l'aérodynamisme d'un véhicule automobile. Un bon aérodynamisme améliore les performances, contribue à l'économie de carburant et augmente la sécurité. We know that it is very important to improve the aerodynamics of a motor vehicle. Good aerodynamics improve performance, contribute to fuel economy and increase safety.
Compte tenu de l'importance de cette question, de nombreuses recherches ont été faites dans le domaine de l'aérodynamisme. Cependant, ces recherches se sont jusqu'à présent limitées à l'étude des formes extérieures des carrosseries, des pare-brises ou à la mise en oeuvre de boucliers ou de volets. En outre , on s'est très peu préoccupé des problèmes d'aérodynamisme au niveau des planchers des véhicules. En effet, l'air qui pénètre sous les tôles, en particulier sous le plancher et le châssis du véhicule est freinez il se produit des turbulences ce qui provoque, bien sur, une résistance à l'avancement du véhicule. Given the importance of this question, much research has been done in the field of aerodynamics. However, this research has so far been limited to the study of the external forms of bodies, windshields or the implementation of shields or shutters. In addition, very little attention was paid to aerodynamic problems in the vehicle floors. In fact, the air which penetrates under the sheets, in particular under the floor and the chassis of the vehicle is braked, turbulence occurs which causes, of course, resistance to the advancement of the vehicle.
L2inventxona pour but dRaméliorer l'aérodynamisme d'unvéhicule à ce niveau. L2inventxona aims to improve the aerodynamics of a vehicle at this level.
Le dispositif aérodynamique de l'invention, montrable sur un véhicule automobile, est caractérisé en ce qu'il comporte un carénage, fixé sous ledit véhicule en vue de faciliter l'écoulement de l'air sous le plancher de celui-ci. The aerodynamic device of the invention, which can be displayed on a motor vehicle, is characterized in that it comprises a fairing, fixed under said vehicle in order to facilitate the flow of air under the floor thereof.
Selon un mode de réalisation préféré de l'invention, > dit carénage s'étend sous toute la surface du plancher du véhicule. Il peut aussi s'étendre sur une partie seulement de cette surface. According to a preferred embodiment of the invention,> said fairing extends under the entire surface of the vehicle floor. It can also extend over only part of this surface.
Selon un autre mode particulier de l'invention, la face du carénage en regard dudit plancher est munie de canaux longitudinaux, de préférence parallèles entre eux et s'étendant sous les éléments dudit véhicule faisant saillie du plancher. According to another particular embodiment of the invention, the face of the fairing opposite said floor is provided with longitudinal channels, preferably parallel to each other and extending under the elements of said vehicle projecting from the floor.
De préférence, lesdits canaux s'étendent sur sensiblement toute la longueur du carénage. Preferably, said channels extend over substantially the entire length of the fairing.
Selon un autre mode de réalisation-préféré de l'invention, ledit carénage est réalisé en une polyoléfine, tel que le polyéthylène. According to another preferred embodiment of the invention, said fairing is made of a polyolefin, such as polyethylene.
Le dispositif de l'invention améliore très sensiblement l'aérodynamisme du véhicule sur lequel il est monté. En particulier, tous les éléments faisant saillie du plancher, tels que les parties en relief des carters, les organes de transmissions, les réservoirs, n'offrent plus de résistance à l'air et celui-ci est canalisé entre les canaux parallèles s'étendant sous ces éléments. The device of the invention very significantly improves the aerodynamics of the vehicle on which it is mounted. In particular, all the elements projecting from the floor, such as the raised parts of the casings, the transmission members, the tanks, no longer offer resistance to air and the latter is channeled between the parallel channels. extending under these elements.
Le dispositif de l'invention élimine tout tourbillon ou turbulence d'air et effectue une évacuation dirigée de celui-ci, sous le véhicule, grâce aux canaux parallèles précités . Ceci a pour conséquence d'augmenter la stabilité directionnelle du véhicule, lesdits canaux produisant un effet comparable à celui produit par la quille ou la coque d'un bateau avançant dans l'eau. The device of the invention eliminates any vortex or turbulence of air and performs a directed evacuation thereof, under the vehicle, using the aforementioned parallel channels. This has the effect of increasing the directional stability of the vehicle, said channels producing an effect comparable to that produced by the keel or hull of a boat advancing in the water.
En conséquence, le dispositif de l'invention permet d'augmenter la vitesse du véhicule tout en réalisant des économies de carburant et en améliorant les conditions de sécurité, grâce à irne meilleure tenue de route du véhicule. Par ailleurs, le dispositif assure une protection supplémentaire du châssis, du plancher et des organes du véhicule situés au niveau de celui-ci. En outre, le dispositif améliore l'étanchéité, par exemple il sert d'écran au plancher contre la poussière et l'eau. Consequently, the device of the invention makes it possible to increase the speed of the vehicle while achieving fuel savings and improving safety conditions, thanks to a better handling of the vehicle. Furthermore, the device provides additional protection for the chassis, the floor and the components of the vehicle located at the level thereof. In addition, the device improves the seal, for example it serves as a screen for the floor against dust and water.
On notera aussi que le dispositif de l'invention permet d'améliorer l'isolation thermique et phonique du véhicule contribuant ainsi à augmenter le confort de celui-ci. It will also be noted that the device of the invention makes it possible to improve the thermal and sound insulation of the vehicle thus contributing to increasing the comfort thereof.
Enfin, les polyoléfines, notamment le polyéthylène, s'avèrent particulièrement adaptées comme matériau pour réaliser le carénage de l'invention. En effet, les polyoléfines sont caractérisées par leur excellente tenue aux hydrocarbures, leur bonne résistance aux chocs et par le fait qutelles conservent leur flexibilité à des températures très basses. En outre, la boue, la neige ou la glace n'y adhèrent pas. Finally, polyolefins, in particular polyethylene, prove to be particularly suitable as a material for carrying out the fairing of the invention. Indeed, polyolefins are characterized by their excellent resistance to hydrocarbons, their good impact resistance and by the fact that they retain their flexibility at very low temperatures. In addition, mud, snow or ice does not adhere to it.
L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparattront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant différents modes de réalisation de l'invention et dans lequels

En faisant référence à la figure 1, on peut voir un véhicule 1 muni du dispositif aérodynamique 2 de l'invention. Ce dispositif comporte un carénage 3 fixé sous le plancher 4 du véhicule. De préférence, le carénage 3 s' étend sensiblement sous toute la surface du plancher du véhicule, par exemple de la calandre ou du pare-choc avant 5 jusqu'au voisinage de la partie arrière du véhicule,par exemple de son pare-choc arrière26. Referring to Figure 1, one can see a vehicle 1 provided with the aerodynamic device 2 of the invention. This device comprises a fairing 3 fixed under the floor 4 of the vehicle. Preferably, the fairing 3 extends substantially under the entire surface of the vehicle floor, for example of the grille or the front bumper 5 as far as the vicinity of the rear part of the vehicle, for example of its rear bumper26 .
Le profil longitudinal du carénage 3 correspondra, de préférence, sensiblement à celui du plancher 4. The longitudinal profile of the fairing 3 will preferably correspond substantially to that of the floor 4.
En outre, la face du carénage 3 en regard du plancher 4 pourra présenter des parties en creux 6, 7 correspondant respectivement à l'essieu avant 8 et à l'essieu et au pont arrière 9 du véhicule.In addition, the face of the fairing 3 opposite the floor 4 may have recessed portions 6, 7 corresponding respectively to the front axle 8 and to the axle and to the rear axle 9 of the vehicle.
Le carénage sera de préférence fixé avec un certain décalage, de l'ordre de 1 à 2 cm, par rapport au plancher du véhicule. Un tel montage permet une certaine circulation d'air entre le carénage et le plancher ce qui empêche la corrosion ou la rouille de celui-ci. The fairing will preferably be fixed with a certain offset, of the order of 1 to 2 cm, relative to the floor of the vehicle. Such an arrangement allows some air circulation between the fairing and the floor, which prevents corrosion or rusting of the latter.
Le carénage est fixé au plancher par tout moyen connu, par exemple par des vis. Il pourra être monobloc ou réalisé en plusieurs éléments. The fairing is fixed to the floor by any known means, for example by screws. It can be in one piece or made of several elements.
En faisant référence maintenant à la figure 2, on peut voir un élément 10 du carénage conforme à un premier mode de réalisation de l'invention. La face il de cet élément qui est en regard du plancher du véhicule , lorsque le carénage y est fixé, est munie de canaux longitudinaux tels que 12, 13, c'est-à-dire s'étendant de l'avant vers l'arrière du véhicule. De préférence, ces canaux sont parallèles entre eux. De plus, ils s'étendent sous les éléments du véhicule faisant saillie des planchers. Ces éléments peuvent être des parties en relief de carters ou de réservoirs, ou des organes de transmission ou toutes autres aspérités susceptibles d'opposer une résistance à l'avancement du véhicule. Ces éléments en saillie viendront donc se loger, au moins en partie, dans lesdits canaux lors de la mise en place du carénage .Par exemple, le canal 13 peut s'étendre sous l'arbre de transmission reliant le moteur au pont arrière. Referring now to Figure 2, we can see an element 10 of the fairing according to a first embodiment of the invention. The face il of this element which is opposite the vehicle floor, when the fairing is attached thereto, is provided with longitudinal channels such as 12, 13, that is to say extending from the front towards the rear of the vehicle. Preferably, these channels are parallel to each other. In addition, they extend under the elements of the vehicle projecting from the floors. These elements can be raised parts of casings or tanks, or transmission members or any other roughness likely to oppose resistance to the advancement of the vehicle. These projecting elements will therefore be housed, at least in part, in said channels when the fairing is put in place. For example, channel 13 can extend under the drive shaft connecting the engine to the rear axle.
De préférence, lesdits canaux s'étendent sur sensible ment toute lalongueur du carénage.Par ailleurs, ils présentent une section transversale qui peut être soit semi-circulaire, comme dans le cas du canal 12, soit triangulaire, comme dans le cas du canal 13. Le type de section sera choisi en fonction de l'élément en saillie sous lequel vient se placer le canal. Preferably, said channels extend over substantially the entire length of the fairing. Furthermore, they have a cross section which can be either semi-circular, as in the case of channel 12, or triangular, as in the case of channel 13. The type of section will be chosen according to the projecting element under which the channel is placed.
Des emplacements sur chaque élément de carénage 10 seront prévus pour la fixation au plancher. On a repéré par des traits d'axe 14 de tels emplacements pour le passage , par exemple, de vis de fixation. Locations on each fairing element 10 will be provided for attachment to the floor. These locations have been identified by axis lines 14 for the passage, for example, of fixing screws.
L'élément 10 est muni sur chacun de ses côtés longitudinaux d'une bordure 15 tournée en direction du plancher du véhicule. The element 10 is provided on each of its longitudinal sides with an edge 15 facing towards the floor of the vehicle.
Un regard 16 peut Qtre prévu dans l'élément de carénage, notamment pour l'accès à certains éléments du véhicule tels que les orifices de vidange degndssagedecon- trolle oud'entretien.Un tel.regard rend inutile la dépose du carénage notamment lorsqu'on désire effectuer une vidange. A manhole 16 can be provided in the fairing element, in particular for access to certain elements of the vehicle such as the drain or degndssagedecontrol or maintenance orifices. Such a look makes it unnecessary to remove the fairing especially when want to drain.
La figure 3 illustre un autre mode de réalisation de l'invention. On peut voir dans cette figure deux éléments 17, 18 formant une partie du carénage de l'invention. Ces éléments sont constitués suivant le même principe que l'élément 10 qui vient autre décrit. FIG. 3 illustrates another embodiment of the invention. We can see in this figure two elements 17, 18 forming part of the fairing of the invention. These elements are constituted according to the same principle as the element 10 which has just been described.
Néanmoins, ils présentent des différences de forme par rapport à celui-ei. En particulier, ils sont munis de canaux longitudinaux 19, 20 disposés symétriquement par rapport à un canal central 21. Tous ces canaux présentent une section semi-circulaire. Un regard 22 est prévu sur l'élément 17. Les éléments 17 et 18 sont pourvus sur leurs côtés longitudinaux d'une bordure 23 tournée vers le sol.Nevertheless, they present differences of form compared to this one. In particular, they are provided with longitudinal channels 19, 20 arranged symmetrically with respect to a central channel 21. All these channels have a semi-circular section. A look 22 is provided on the element 17. The elements 17 and 18 are provided on their longitudinal sides with an edge 23 facing towards the ground.
Les traits d'axe 24 indiquent un emplacement possible pour le passage de vis de fixation. The axis lines 24 indicate a possible location for the passage of fixing screws.
Comme cela apparaît sur les figures 3 et 4, les éléments 17 et 18 sont assemblés entre eux par embot~tement. As shown in Figures 3 and 4, the elements 17 and 18 are assembled together by embot ~ tement.
Par exemple, l'élément 18 peut comporter sur la bordure d'un de ses c8tés latéraux une languette 25 destinée à venir s'emboîter dans un évidement correspondant, non représenté, prévu sur une face etenkordure d'unc & latéral de ltéMment 17. Le trait d'axes 27 indiquent un emplacement possible pour les vis de fixation des deux éléments l'un à l'autre.For example, the element 18 may comprise on the edge of one of its lateral sides a tongue 25 intended to come to fit in a corresponding recess, not shown, provided on a side and side edge of a side 17. The center line 27 indicates a possible location for the screws for fixing the two elements to each other.
Naturellement de nombreuses variantes de l'kventon sontpossibl. Naturally many variants of the kventon are possible.
On comprendra tout d'abord que l'invention n'est pas limitée aux modes deréalisation qui viennent autre décrits. En particulier, la forme des éléments de carénage sera adaptée aux formes spécifiques des planchers et des structures propres à chaque type de véhicule.Les regards pourront être disposés en des emplacements quelconques du carénage, en fonction de la disposition des organes mécaniques du véhicule. It will be understood first of all that the invention is not limited to the embodiments which come other described. In particular, the shape of the fairing elements will be adapted to the specific shapes of the floors and structures specific to each type of vehicle. The manholes may be arranged in any locations of the fairing, depending on the arrangement of the mechanical members of the vehicle.
D'autre part, on pourra concevoir tout. autre système d'assemblage convenable des différents éléments formant le carénage. Par ailleurs, bien qu'il soit préférable que les canaux s'étendent sur toute la longueur du carénage, il est possible de concevoir que les canaux, ou tout au moins une partie de ceux-ci, ne s'étendent que sur une portion du carénage. On the other hand, we can design everything. another suitable assembly system for the various elements forming the fairing. Furthermore, although it is preferable that the channels extend over the entire length of the fairing, it is possible to conceive that the channels, or at least a part of them, extend only over a portion of the fairing.
Dien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et représentés qui n'ont été donnés qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre de la protection comme revendiquée. Of course, the invention is in no way limited to the embodiments described and shown which have been given only by way of example. In particular, it includes all the means constituting technical equivalents of the means described as well as their combinations if these are executed according to the spirit and implemented in the context of protection as claimed.
