Abstract
Description
L'invention se rapporte au domaine des roues de véhicules automobiles et concerne plus particulièrement les roues ayant une jante et un voile de roue réalisés en des matériaux différents.The invention relates to the field of motor vehicle wheels and relates more particularly to wheels having a rim and a wheel wall produced from different materials.
Une roue se compose essentiellement d'un voile de roue de forme circulaire sur lequel est monté le moyeu et d'une jante destinée à recevoir un pneumatique. La jante et le voile sont fixés I'un à I'autre, le plus souvent par soudage.A wheel essentially consists of a wheel wall of circular shape on which the hub is mounted and a rim intended to receive a tire. The rim and the web are attached to each other, most often by welding.
Pour des questions d'esthétique et pour diminuer le poids de la roue, on réalise souvent le voile par emboutissage en aluminium, alliage d'aluminium ou autre alliage léger. Cependant, afin de conserver les caractéristiques mécaniques de la roue et notamment la résistance aux chocs, il est nécessaire que la jante soit en un matériau résistant comme l'acier. For aesthetic reasons and to reduce the weight of the wheel, the veil is often made by stamping aluminum, aluminum alloy or other light alloy. However, in order to preserve the mechanical characteristics of the wheel and in particular the impact resistance, it is necessary for the rim to be made of a resistant material such as steel.
Or, il nest pas toujours possible de souder deux matériaux différents, notamment I'acier et l'aluminiun. Dans ce cas, la jante et le voile sont fixés l'un à l'autre par des moyens tels que vissage, rivetage, clippage. However, it is not always possible to weld two different materials, notably steel and aluminum. In this case, the rim and the web are fixed to each other by means such as screwing, riveting, clipping.
Ces procédés sont relativement longs à mettre en oeuvre et/ou n'assurent pas toujours une fixation ìable. These methods are relatively long to implement and / or do not always provide an easy fixation.
L'invention a pour but de remédier à ces inconvénients en proposant une roue, notamment de véhicule automobile, présentant une jante et un voile de roue réalisés en des matériaux différents qui puissent être fixés l'un à l'outre facilement et de manière fiable Selon la principale caractéristique de l'inven- tion, la jante et le voile sont fixés l'un à l'autre par clinchage.The object of the invention is to remedy these drawbacks by proposing a wheel, in particular for a motor vehicle, having a rim and a wheel disc made of different materials which can be fixed together easily and reliably. According to the main characteristic of the invention, the rim and the web are fixed to each other by clinching.
On entend par "clinchage" l'assemblage à froid des matières obtenu par linterpénétration des éléments à assembler. Dans le cas de deux tôles, le clinchage peut être réalisé par emboutissage de ces deux tôles entre un poinçon et une matrice qui pré sente une cavité ayant une forme apte à créer un repli rendant impossible toute séparation ultérieure des deux pièces.By clinching is meant the cold assembly of the materials obtained by the interpenetration of the elements to be assembled. In the case of two sheets, clinching can be achieved by stamping these two sheets between a punch and a die which has a cavity having a shape capable of creating a fold making any subsequent separation of the two parts impossible.
Le clinchage peut être effectué en plusieurs zones réparties suivant le pourtour de la roue et une zone de clinchage peut comporter un ou plusieurs points de clinchage.Clinching can be carried out in several zones distributed along the circumference of the wheel and a clinching zone can comprise one or more clinching points.
Dans le cas où la jante présente une gorge par laquelle elle est en contact avec le voile de roue, les points de clinchage sont situés sur cette gorge. Si la jante et le voile de roue sont en contact I'un avec l-autre suivant une surface conique de liaison, les points de clinchage sont situés sur cette dernière.In the case where the rim has a groove through which it is in contact with the wheel disc, the clinching points are located on this groove. If the rim and the wheel disc are in contact with each other along a conical connecting surface, the clinching points are located on the latter.
Enfin, selon un dernier aspect de l'invention, le voile de roue est en aluminium ou en un alliage léger tel qu'un alliage d'aluminium tandis que la jante est en un matériau tel que l-acier. Finally, according to a last aspect of the invention, the wheel arch is made of aluminum or a light alloy such as an aluminum alloy while the rim is made of a material such as l-steel.
L'invention apparaîtra mieux à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :
- la Figure 1 est une vue schématique en coupe dune roue
de véhicule automobile conforme à l-invention
- la Figure 2 est une vue en coupe à échelle agrandie d'un
point de clinchage de la roue de la figure 1;
- la Figure 3 est une vue partielle semblable à la figure
1 montrant comment une zone de clinchage peut comporter
plusieurs points de clinchage;
- la Figure 4 est une vue semblable à la figure 1 illus
trant un deuxième mode de réalisation d'une roue conforme
à I'invention; et
- la Figure 5 est une vue en coupe à échelle agrandie d'un
point de clinchage de la roue de la figure 4.The invention will appear better on reading the description which follows, given solely by way of example and made with reference to the appended drawings in which:
- Figure 1 is a schematic sectional view of a wheel
motor vehicle according to the invention
- Figure 2 is a sectional view on an enlarged scale of a
clinching point of the wheel of FIG. 1;
- Figure 3 is a partial view similar to the figure
1 showing how a clinching area can include
several clinching points;
- Figure 4 is a view similar to Figure 1 illus
trant a second embodiment of a conforming wheel
to the invention; and
- Figure 5 is a sectional view on an enlarged scale of a
clinching point of the wheel of figure 4.
La figure 1 montre une roue de véhicule, portant la référence générale 1, qui se compose essentiellement d'un voile de roue 2 présentant en son centre une ouverture 3 destinée à recevoir un moyeu (non représenté) et sur lequel est fixée une jante 4 destinée à loger un pneumatique 5. Dans un but de simplification, les autres éléments de la roue n'ont pas été représentés sur les figures.Figure 1 shows a vehicle wheel, bearing the general reference 1, which essentially consists of a wheel wall 2 having in its center an opening 3 intended to receive a hub (not shown) and on which a rim 4 is fixed intended to accommodate a tire 5. For the sake of simplification, the other elements of the wheel have not been shown in the figures.
Dans I'exemple illustré à la figure 1, la jante 4 présente une gorge 6 par laquelle elle est fixée à un rebord 7 situé à la périphérie du voile 2. Selon l-inventionv cette fixation est effectuée par clinchage en des points de clinchage tels que 8.In the example illustrated in FIG. 1, the rim 4 has a groove 6 by which it is fixed to a flange 7 situated at the periphery of the web 2. According to the invention, this fixing is carried out by clinching at clinching points such than 8.
La figure 2 montre à échelle agrandie le point de clinchage 8 situé à la partie supérieure de la roue de la figure 1. On voit qu'à cet endroit, la jante 4 et le rebord 7 du voile 2 ont été déformés par clinchage, c'est-à-dire dans ce cas par emboutissage entre un poinçon de forme sensiblement cylindrique et une matrice dans laquelle est ménagée une cavité dont les parois s'évasent de lvouverture vers le fond. Après cette opération, la face extérieure de la jante 4 présente une dépression 9 ayant sensiblement la forme du poinçon. Sa face intérieure ainsi que le voile de roue 2 présentent un repli 10, correspondant à la forme de la cavité. La zone de contact entre les deux tôles présente donc une section en Z tout autour de la dépression 9, rendant impossible toute séparation ultérieure des deux pièces et réalisant ainsi une étanchéité parfaite.FIG. 2 shows on an enlarged scale the clinching point 8 situated at the upper part of the wheel of FIG. 1. It can be seen that at this point, the rim 4 and the flange 7 of the web 2 have been deformed by clinching, c that is to say in this case by stamping between a punch of substantially cylindrical shape and a die in which is formed a cavity whose walls widen from the opening towards the bottom. After this operation, the outer face of the rim 4 has a depression 9 having substantially the shape of the punch. Its inner face and the wheel disc 2 have a fold 10, corresponding to the shape of the cavity. The contact zone between the two sheets therefore has a Z-shaped section all around the depression 9, making any subsequent separation of the two parts impossible and thus achieving perfect sealing.
Le clinchage est effectué en plusieurs zones de clinchage réparties sur le pourtour de la roue (par exemple trois zones à 1200 ou quatre zones à 90*). Sur la figure 1, les zones de clinchage visibles à la partie supérieure et à la partie infé rieure de la roue ne comportent qu'un seul point de clinchage 8, mais il pourrait y en avoir plusieurs comme cela est illustré à la figure 3* le nombre et la disposition des points de clinchage seront déterminés dans chaque cas particulier en fonction des caractéristiques mécaniques demandées
Sur cette figure, on voit que la zone de clinchage 11, située à la partie supérieure de la roue 1, comporte deux points de clinchage raz et 8b situés dans un même plan radial de la roue (qui est le plan de la figure 3). Bien entendu, on ne sortirait pas du cadre de l'invention en prévoyant, dans une zone donnée, un nombre de points de clinchage différent, ou en les disposant autrement, par exemple suivant une direction périphérique (c'est-à-dire perpendiculaire au plan de la figure 3).Clinching is carried out in several clinching zones distributed around the circumference of the wheel (for example three zones at 1200 or four zones at 90 *). In FIG. 1, the clinching zones visible at the upper part and at the lower part of the wheel have only one clinching point 8, but there could be several as illustrated in FIG. 3 * the number and arrangement of clinching points will be determined in each particular case according to the mechanical characteristics requested
In this figure, it can be seen that the clinching zone 11, located at the upper part of the wheel 1, comprises two clinching points flush and 8b situated in the same radial plane of the wheel (which is the plane of FIG. 3) . Of course, it would not be departing from the scope of the invention to provide, in a given area, a different number of clinching points, or by arranging them otherwise, for example in a peripheral direction (that is to say perpendicular in the plan of figure 3).
La figure 4 montre un deuxième mode de réalisation d'une roue conforme à lwinvention dans lequel le voile de roue 2 présente, à sa périphérie, une surface conique 12 par laquelle il est fixé à la jante 4. C'est sur cette surface 12 que se trouvent les points de clinchage 8.FIG. 4 shows a second embodiment of a wheel in accordance with the invention in which the wheel disc 2 has, at its periphery, a conical surface 12 by which it is fixed to the rim 4. It is on this surface 12 that the clinching points are 8.
La figure 5 illustre à échelle agrandie un point de clinchage de ce second mode de réalisation. Dans ce cas, c'est le voile 2 qui présente, sur sa face extérieure, une dépression 13 correspondant à la forme du poinçon tandis que sa face intérieure et la jante 4 présentent un repli 14 ayant une section en Z. Il est bien entendu qu'on ne sortirait pas du cadre de l'inven- tion, aussi bien sur la figure 2 que sur la figure 5, en inversant le sens du clinchage.FIG. 5 illustrates on an enlarged scale a clinching point of this second embodiment. In this case, it is the web 2 which has, on its outer face, a depression 13 corresponding to the shape of the punch while its inner face and the rim 4 have a fold 14 having a Z section. It is understood that it would not go beyond the scope of the invention, both in FIG. 2 and in FIG. 5, by reversing the direction of clinching.
L'invention présente de nombreux avantages puisqu elle permet de réaliser facilement une roue dans laquelle la jante et le voile de roue sont en des matériaux différents. Le clinchage est une opération simple et rapide, donc d-un faible cout de revient, qui permet d~obtenir une fixation sure et fiable ainsi qu'une étanchéité parfaite au niveau de la jante. Enfin, le voile et la jante peuvent conserver leurs revêtements initiaux, ce qui ameliore I'esthétique de la roue.The invention has many advantages since it makes it possible to easily produce a wheel in which the rim and the wheel disc are made of different materials. Clinching is a simple and fast operation, therefore of a low cost price, which allows to obtain a secure and reliable fixing as well as a perfect seal at the rim. Finally, the web and the rim can keep their original coatings, which improves the aesthetics of the wheel.
Enfin, il est bien entendu que l'invention ne se limite pas aux modes de réalisation décrits et représentés, mais qu'on peut imaginer de nombreuses variantes sans sortir du cadre de l-in- Invention C'est ainsi qu'on pourra faire varier le nombre et l'emplacement des points de clinchage en fonction de chaque cas particulier et que ceux-ci peuvent se trouver ailleurs que sur la gorge de la jante ou une surface conique de liaison, pourvu que la surface de contact entre la jante et le voile puisse être pincée entre le poinçon et la matrice. Finally, it is understood that the invention is not limited to the embodiments described and shown, but that one can imagine many variants without departing from the scope of the invention. This is how we can do vary the number and location of clinching points according to each particular case and that these can be located elsewhere than on the groove of the rim or a conical connecting surface, provided that the contact surface between the rim and the veil can be pinched between the punch and the matrix.
