Description

Pare-boue perfectionné de véhicule automobile et véhicule équipé d'un tel pare-boue Advanced mudguard for a motor vehicle and vehicle equipped with such a mudguard
L'invention concerne un pare-boue de véhicule automobile, comprenant une paroi concave prévue pour être fixée à la carrosserie du véhicule et pour entourer partiellement une roue du véhicule.The invention relates to a motor vehicle fender, comprising a concave wall adapted to be fixed to the vehicle body and to partially surround a wheel of the vehicle.
On a remarqué que les pare-boue étaient le siège de phénomènes vi- bratoires à l'origine du passage de bruits depuis l'extérieur du véhicule vers l'habitacle, et que les dispositifs connus d'isolation phonique perdaient de leur efficacité selon les positions relatives de la caisse et des liaisons au sol.It has been noted that the mud flaps were the site of vibration phenomena causing the passage of noises from the outside of the vehicle towards the passenger compartment, and that the known soundproofing devices lost their effectiveness according to the relative positions of the body and the ground connections.
L'invention a pour but d'améliorer l'isolation acoustique de l'habitacle vis-à-vis de l'extérieur, au niveau des roues du véhicule, quel que soit le débat- tement de suspension supporté par le véhicule.The invention aims to improve the acoustic insulation of the passenger compartment vis-à-vis the outside, at the wheels of the vehicle, regardless of the suspension debate supported by the vehicle.
A cet effet, l'invention a pour objet un pare-boue du type exposé ci- dessus, comprenant en outre une paroi d'isolation phonique, reliée à ladite paroi concave par l'intermédiaire d'une liaison déformable, et adaptée pour être fixée à une pièce de la liaison au sol associée à la roue. Suivant d'autres caractéristiques de l'invention, prises seules ou selon toutes les combinaisons envisageables :To this end, the subject of the invention is a mudguard of the type set out above, further comprising a soundproofing wall, connected to said concave wall via a deformable link, and adapted to be attached to a part of the ground connection associated with the wheel. According to other features of the invention, taken alone or according to any conceivable combination:
- la liaison déformable comprend un volet plié en accordéon ;the deformable connection comprises an accordion-folded flap;
- le volet est adapté pour constituer un écran d'isolation phonique autour de l'axe de roue ; - le pare-boue est réalisé d'une pièce ; etthe shutter is adapted to form a soundproofing screen around the wheel axle; - the mudguard is made in one piece; and
- le pare-boue est réalisé en matière plastique, notamment par moulage par injection ou par soufflage.- The mudguard is made of plastic, in particular by injection molding or blowing.
L'invention vise également un véhicule automobile comprenant au moins un pare-boue du type exposé précédemment. Des formes particulières de réalisation de l'invention vont maintenant être décrites plus en détail en référence aux dessins annexés sur lesquels :The invention also relates to a motor vehicle comprising at least one mudguard of the type described above. Particular embodiments of the invention will now be described in more detail with reference to the accompanying drawings in which:
- la figure 1 est une vue schématique en perspective d'un pare-boue de véhicule automobile, conformément à un premier mode de réalisation de l'invention ; - la figure 2 est une vue schématique en coupe axiale, dans le plan vertical 2-2 indiqué sur la figure 1 , d'une roue de véhicule automobile, d'une liaison au sol associée, et du pare-boue de la figure 1 monté sur la carrosserie du véhicule ;- Figure 1 is a schematic perspective view of a motor vehicle mudguard, according to a first embodiment of the invention; FIG. 2 is a diagrammatic view in axial section, in the vertical plane 2-2 shown in FIG. 1, of a motor vehicle wheel, a associated ground connection, and the mudguard of Figure 1 mounted on the vehicle body;
- la figure 3 est une vue analogue à la figure 1 , illustrant un deuxième mode de réalisation de l'invention. Sur la figure 1 , on a représenté un pare-boue 1 de véhicule automobile, conforme à un premier mode de réalisation de l'invention.- Figure 3 is a view similar to Figure 1, illustrating a second embodiment of the invention. In Figure 1, there is shown a mudguard 1 of a motor vehicle, according to a first embodiment of the invention.
Ce pare-boue 1 comprend essentiellement une paroi concave 3, une plaque 5 de fixation à la carrosserie, une paroi 7 d'isolation phonique, et un volet 9 de liaison entre la paroi concave 3 et la paroi d'isolation phonique 7. La paroi concave 3 présente une forme générale incurvée prévue pour entourer partiellement une roue du véhicule , lorsque le pare-boue est fixé sur la carrosserie.This mudguard 1 essentially comprises a concave wall 3, a plate 5 for attachment to the bodywork, a soundproofing wall 7, and a connecting flap 9 between the concave wall 3 and the sound-insulating wall 7. concave wall 3 has a generally curved shape intended to partially surround a wheel of the vehicle, when the mudguard is attached to the bodywork.
Dans tout ce qui suit, les termes "interne" et "externe" s'entendront par rapport à la courbure générale de la pièce, les faces internes d'une pièce étant celles tournées vers la roue.In all that follows, the terms "internal" and "external" will be understood in relation to the general curvature of the part, the internal faces of a part being those facing the wheel.
En outre, les termes d'orientation comme "longitudinal" ou "latéral" s'entendront par rapport à l'orientation générale du véhicule, sur lequel le pare- boue 1 est supposé monté. D'autre part, l'axe longitudinal du véhicule est supposé horizontal. La paroi concave 3 comprend une bande supérieure 11 ayant une section, dans un plan médian longitudinal et vertical P, essentiellement en forme de C.In addition, the orientation terms such as "longitudinal" or "lateral" will be understood in relation to the general orientation of the vehicle, on which the mudguard 1 is supposed to be mounted. On the other hand, the longitudinal axis of the vehicle is assumed horizontal. The concave wall 3 comprises an upper band 11 having a section, in a longitudinal and vertical central plane P, substantially C-shaped.
La paroi concave 3 comprend également, obturant une face latérale du C, une paroi de fermeture 13 également concave. La plaque de fixation 5 est solidaire de la bande supérieure 11 , et s'étend à partir d'une extrémité du C.The concave wall 3 also comprises, closing a side face of the C, a closure wall 13 also concave. The fixing plate 5 is integral with the upper band 11, and extends from one end of the C.
La paroi d'isolation 7 est essentiellement plane et s'étend parallèlement au plan longitudinal P. Elle est reliée par son bord supérieur au bord inférieur de la paroi de fermeture 13, par l'intermédiaire du volet 9. La paroi d'isolation 7 est en outre formée avec une lumière 15 de fixation à une pièce de liaison au sol associée à la roue.The insulation wall 7 is essentially flat and extends parallel to the longitudinal plane P. It is connected by its upper edge to the lower edge of the closure wall 13, through the flap 9. The insulation wall 7 is furthermore formed with a fixing light 15 to a ground connection piece associated with the wheel.
Le volet 9 est plié en accordéon, suivant des plis parallèles orientés de façon longitudinale, parallèlement au bord inférieur de la paroi de fermeture 13 et au bord supérieur de la paroi d'isolation 7. De préférence, le pare-boue 1 est réalisé d'une pièce, par exemple en matière plastique injectée ou soufflée.The shutter 9 is folded in accordion, according to parallel folds oriented longitudinally, parallel to the lower edge of the closure wall 13 and the upper edge of the insulation wall 7. Preferably, the mudguard 1 is made in one piece, for example injected or blown plastic material.
La paroi concave 3 et la plaque de fixation 5 sont dotées d'une pluralité de trous 17, ou plus généralement d'organes de fixation, servant à fixer le pare-boue 1 sur la caisse (ou carrosserie) du véhicule.The concave wall 3 and the fixing plate 5 are provided with a plurality of holes 17, or more generally fasteners, for fixing the mudguard 1 to the body (or bodywork) of the vehicle.
Sur la figure 2, on a représenté le pare-boue 1 de la figure 1 monté sur la caisse 20 d'un véhicule.In Figure 2, there is shown the mudguard 1 of Figure 1 mounted on the body 20 of a vehicle.
Sur cette figure, on a illustré le fait que la paroi concave 3 est fixée rigidement, par l'intermédiaire des trous de fixation 17, à la caisse 20 de façon à entourer partiellement la roue associée 21.In this figure, it is illustrated that the concave wall 3 is fixed rigidly, via the fixing holes 17, to the body 20 so as to partially surround the associated wheel 21.
La roue 21 est reliée à la caisse par l'intermédiaire d'une liaison au sol schématisée sous la référence 23, susceptible de débattement et de déplacement par rapport à la caisse 20. La référence numérique générale 23 désigne également en particulier l'une des pièces de la liaison au sol, telle que le triangle de suspension.The wheel 21 is connected to the body by means of a ground connection shown schematically under the reference 23, capable of deflection and displacement relative to the body 20. The general reference numeral 23 also designates in particular one of the parts of the ground connection, such as the wishbone.
Dans l'exemple représenté, le triangle de suspension est engagé au travers de la lumière 15, de telle sorte que la paroi d'isolation 7 est fixée à ce triangle de suspension 23.In the example shown, the suspension triangle is engaged through the light 15, so that the insulation wall 7 is fixed to this suspension triangle 23.
Ainsi, lors de déplacements ou débattements de suspension de la roue 21 et de la liaison au sol 23 par rapport à la caisse 20, la paroi d'isolation 7 se déplace solidairement en sollicitant le volet 9 en déformation correspondante (en étirement ou en contraction) .Thus, during displacements or deflections of suspension of the wheel 21 and the ground connection 23 with respect to the body 20, the insulating wall 7 moves in solidarity by biasing the flap 9 in corresponding deformation (in stretching or contraction ).
La paroi d'isolation 7 et le volet 9 constituent des écrans d'isolation phonique qui limitent la propagation, le long des axes de roue, des phénomènes vibratoires sonores prenant naissance au voisinage de la roue.The insulating wall 7 and the flap 9 constitute sound insulation screens which limit the propagation along the wheel axles of the vibratory sound phenomena originating in the vicinity of the wheel.
La paroi d'isolation 7 ainsi que le volet 9 contribuent ainsi, en accompagnant les déplacements en débattement de la roue et de la liaison au sol, à limiter la propagation de certains bruits vers l'intérieur de l'habitacle.The insulating wall 7 and the flap 9 thus contribute, by accompanying displacements in displacement of the wheel and the connection to the ground, to limit the propagation of certain noises towards the interior of the passenger compartment.
Sur la figure 3, on a représenté un pare-boue 101 conforme à un deuxième mode de réalisation de l'invention.In Figure 3, there is shown a mudguard 101 according to a second embodiment of the invention.
Ce pare-boue 101 est analogue, dans sa constitution, au pare-boue 1 décrit précédemment, la paroi concave 3 et la plaque de fixation 5 étant similaires ou identiques aux précédentes. Le pare-boue 101 ne diffère du pare-boue 1 décrit précédemment qu'en ce que la paroi disolation 107 et le volet 9 s'étendent le long du bord inférieur de la paroi de fermeture 13 sur une longueur plus importante, et de façon continue sur le bord inférieur d'extrémité de la bande 1 1 , du côté opposé à la plaque de fixation 5.This mudguard 101 is similar in its constitution to the mudguard 1 described above, the concave wall 3 and the fixing plate 5 being similar or identical to the previous ones. The mudguard 101 differs from the mudguard 1 described above only in that the insulation wall 107 and the flap 9 extend along the lower edge of the closure wall 13 over a longer length, and so continuous on the lower end edge of the band 1 1, the opposite side to the fixing plate 5.
Ainsi, la paroi 107 et le volet 109 sont coudés avec une portion s'étendant sensiblement suivant un plan longitudinal, et une portion s'étendant sensiblement suivant un plan transversal.Thus, the wall 107 and the flap 109 are bent with a portion extending substantially along a longitudinal plane, and a portion extending substantially in a transverse plane.
Le montage du pare-boue 101 sur la caisse du véhicule et son fonctionnement sont en tous points analogues à ce qui a été décrit pour le mode de réalisation précédent, et ne seront donc pas décrits à nouveau. The mounting of the mudguard 101 on the vehicle body and its operation are in all respects similar to that described for the previous embodiment, and will not be described again.
