Description
La présente invention concerne une roue pour un véhicule, notamment pour un véhicule automobile, a fréquence de résonnance optimisée.The present invention relates to a wheel for a vehicle, in particular for a motor vehicle, with an optimized resonance frequency.
La présente invention concerne plus particulièrement une roue qui comprend une jante pour monter un pneumatique, un moyeu pour le montage de la roue sur le véhicule et un voile qui relie la jante au moyeu, ladite roue comportant moins une pièce de recouvrement qui est solidarisé contre une paroi du voile et qui permet d’optimiser la fréquence de résonnance de la roue.The present invention relates more particularly to a wheel which comprises a rim for mounting a tire, a hub for mounting the wheel on the vehicle and a disc which connects the rim to the hub, said wheel comprising at least one cover piece which is secured against a wall of the veil and which makes it possible to optimize the resonance frequency of the wheel.
Il est connu du document FR-A1-3071772 d’avoir une roue qui comprend une jante pour monter un pneumatique, un moyeu pour le montage de la roue sur le véhicule et un voile qui relie la jante au moyeu, ladite roue comportant moins une pièce de recouvrement qui est solidarisée contre une paroi du voile et qui permet d’optimiser la fréquence de résonnance de la roue.It is known from document FR-A1-3071772 to have a wheel which comprises a rim for mounting a tire, a hub for mounting the wheel on the vehicle and a web which connects the rim to the hub, said wheel comprising at least one cover piece which is secured against a wall of the veil and which makes it possible to optimize the resonance frequency of the wheel.
La pièce de recouvrement est formée dans un matériau composite d’épaisseur constante, ne recouvrant que partiellement la paroi interne ou externe du voile de la roue, rajoutant du poids à des endroits non nécessaires ou créant une discontinuité inertielle qui risque de créer une fatigue des branches de la roue, risquant de dégrader la tenue mécanique du voile de la roue.The cover piece is formed from a composite material of constant thickness, only partially covering the internal or external wall of the wheel flange, adding weight in unnecessary places or creating an inertial discontinuity which risks creating fatigue in the wheels. spokes of the wheel, risking degrading the mechanical strength of the wheel flange.
La roue selon l’invention permet de remédier à cet inconvénient.The wheel according to the invention overcomes this drawback.
Il comporte en effet, selon une première caractéristique, une roue pour un véhicule, notamment pour un véhicule automobile, qui comprend une jante pour monter un pneumatique, un moyeu pour le montage de la roue sur le véhicule et un voile qui relie la jante au moyeu, ladite roue comportant moins une pièce de recouvrement qui est solidarisée contre une paroi du voile, telle que, suivant une direction radiale du voile de la roue, ladite pièce de raccordement présente une épaisseur variable.It comprises in fact, according to a first characteristic, a wheel for a vehicle, in particular for a motor vehicle, which comprises a rim for mounting a tire, a hub for mounting the wheel on the vehicle and a web which connects the rim to the hub, said wheel comprising less than one cover piece which is secured against a wall of the disc, such that, in a radial direction of the disc of the wheel, said connecting piece has a variable thickness.
Selon une première caractéristique de l’invention, le voile comporte une paroi interne qui est destinée à être orientée vers le dispositif de freinage du véhicule lorsque la roue est montée sur le véhicule, ladite pièce de raccordement est solidarisée contre la paroi interne du voile de la roue.According to a first characteristic of the invention, the veil comprises an internal wall which is intended to be oriented towards the braking device of the vehicle when the wheel is mounted on the vehicle, said connecting piece is secured against the internal wall of the veil of wheel.
Selon une deuxième caractéristique de l’invention, la pièce de recouvrement est formée par plusieurs couches d’un matériau composite.According to a second characteristic of the invention, the cover piece is formed by several layers of a composite material.
La variation d’épaisseur de la pièce de recouvrement est obtenue par une variation du nombre de couches du matériau composite.The variation in thickness of the cover piece is obtained by varying the number of layers of the composite material.
Au moins une des couches du matériau composite présente une orientation de ces fibres qui est différente des autres couches.At least one of the layers of the composite material has an orientation of these fibers which is different from the other layers.
Selon une troisième caractéristique de l’invention, la pièce de recouvrement se prolonge du moyeu jusqu’à la jante.According to a third feature of the invention, the cover piece extends from the hub to the rim.
Selon un premier mode de réalisation préférentiel, le voile comportant des ouvertures délimitant des branches, chaque branche est au moins en partie recouverte par une pièce de recouvrement.According to a first preferred embodiment, the veil comprising openings delimiting branches, each branch is at least partly covered by a covering piece.
Selon un second mode de réalisation, le voile comporte une unique pièce de recouvrement.According to a second embodiment, the veil comprises a single covering piece.
La présente invention concerne aussi un véhicule qui comporte une roue avec une telle pièce de recouvrement tel que solidarisée sur la paroi interne de son voile.The present invention also relates to a vehicle which comprises a wheel with such a covering piece as secured to the internal wall of its disc.
Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
En référence à ces dessins, un véhicule comporte une roue 1 qui comprend une jante 2 pour monter un pneumatique, un moyeu 3 pour le montage de la roue 1 sur le véhicule et un voile 4 qui relie la jante 2 au moyeu 3 (seule la roue étant représentée).With reference to these drawings, a vehicle comprises a wheel 1 which comprises a rim 2 for mounting a tire, a hub 3 for mounting wheel 1 on the vehicle and a disc 4 which connects rim 2 to hub 3 (only the wheel being shown).
Sur la figure 1 la roue 1 est représentée avec la face interne de visible, rendant visible la paroi interne 41 du voile 4, permettant de voir une pièce de recouvrement 5 qui est solidarisée contre la paroi interne 41 du voile 4.In Figure 1 the wheel 1 is shown with the inner face visible, making the inner wall 41 of the veil 4 visible, allowing to see a cover piece 5 which is secured against the inner wall 41 of the veil 4.
Est défini comme paroi interne du voile 4 de la roue 1, la paroi du voile 4 qui est destinée à être orientée vers le dispositif de freinage du véhicule lorsque le moyeu 3 est monté sur le véhicule.Is defined as the inner wall of the veil 4 of the wheel 1, the wall of the veil 4 which is intended to be oriented towards the braking device of the vehicle when the hub 3 is mounted on the vehicle.
Le voile 4 comporte cinq ouvertures 42 qui délimitent cinq branches 43, chaque branche 43 étant recouverte par une pièce de recouvrement 5, qui sont toutes identiques.The veil 4 has five openings 42 which delimit five branches 43, each branch 43 being covered by a cover piece 5, which are all identical.
Une telle pièce de recouvrement 5 permet de créer un amortissement acoustique pour une roue 1 réalisée en aluminium où les branches 43 rentrent en résonnance avec une fréquence de résonnance de l’ordre de 300 Hz.Such a cover piece 5 makes it possible to create acoustic damping for a wheel 1 made of aluminum where the branches 43 come into resonance with a resonance frequency of the order of 300 Hz.
Chaque pièce de recouvrement 5 se prolonge du moyeu 3 jusqu’à la jante 2, créant une continuité dans la pièce de recouvrement 5 ainsi solidarisée, ne créant pas de rupture inertielle au niveau des branches 43 lors de la rotation de la roue 1 ce qui serait néfaste pour la tenue mécanique des branches 43 d’une telle roue 1.Each cover piece 5 extends from the hub 3 to the rim 2, creating continuity in the cover piece 5 thus secured, not creating any inertial rupture at the level of the branches 43 during the rotation of the wheel 1 which would be detrimental to the mechanical strength of the branches 43 of such a wheel 1.
Comme plus particulièrement visible sur la figure 2, la pièce de recouvrement 5 présente une épaisseur variable, avec une variation de l’épaisseur qui est préférentiellement orientée suivant une direction radiale du voile 4 de la roue 1.As more particularly visible in Figure 2, the cover piece 5 has a variable thickness, with a variation of the thickness which is preferably oriented in a radial direction of the web 4 of the wheel 1.
Une telle variation de l’épaisseur de la pièce de recouvrement 5 permet de mettre de la matière aux endroits nécessaires pour porter la fréquence de résonnance autour de 400 Hz sans créer de surépaisseur et donc de rajouter inutilement de la masse avec l’excédent d’inertie que cela entraine, aux endroits non nécessaires.Such a variation in the thickness of the cover piece 5 makes it possible to put material in the places necessary to bring the resonance frequency around 400 Hz without creating extra thickness and therefore to add mass unnecessarily with the excess of inertia that this entails, in unnecessary places.
Sur la figure 2 est représentée une vue en coupe suivant une section AA’ avec, du moyeu 3 vers la jante 5, une première épaisseur e1, une deuxième épaisseur e2 et une troisième épaisseur e3 de la pièce de recouvrement 5.In Figure 2 is shown a sectional view along a section AA 'with, from the hub 3 to the rim 5, a first thickness e1, a second thickness e2 and a third thickness e3 of the cover piece 5.
La variation d’épaisseur de la pièce de recouvrement 5 est obtenue par une variation du nombre de couches du matériau composite qui la constitue.The variation in thickness of the cover piece 5 is obtained by varying the number of layers of the composite material which constitutes it.
Chaque couche peut avoir des fibres qui sont orientées suivant différentes directions pour donner plus de souplesse ou plus de rigidité à la pièce de recouvrement 5, permettant obtenir la réponse en fréquence le plus intéressante vis-à-vis du bruit total généré par la roue 1.Each layer can have fibers which are oriented in different directions to give more flexibility or more rigidity to the cover piece 5, making it possible to obtain the most interesting frequency response with respect to the total noise generated by the wheel 1 .
Une telle pièce de recouvrement 5 peut aussi être réalisée en une seule partie pour recouvrir les cinq branches, mais cela rend plus compliqué l’optimisation de l’orientation des fibres qui forcément ne seront pas orientées de la même façon pour chaque branche 43.Such a cover piece 5 can also be made in a single part to cover the five branches, but this makes it more complicated to optimize the orientation of the fibers which necessarily will not be oriented in the same way for each branch 43.
Dans l’exemple tel que représenté, l’épaisseur maximale est obtenue au plus proche du moyeu 3 de la roue 1, avec donc e1 qui est supérieur à e2, lui-même supérieur à e3.In the example as shown, the maximum thickness is obtained closest to the hub 3 of the wheel 1, with therefore e1 which is greater than e2, itself greater than e3.
