Abstract

The invention relates to the wheel of a motor vehicle, which is assembled by crimping and may be of a composite structure. It consists of a disc 1, more particularly made from moulded aluminium, and of a ring 2 generally made of sheet steel assembled on the disc by magnetoforming, and completed, if desired, by a part accommodated under the tyre bead. This type of wheel makes it possible to assemble without welding or screwing similar or different materials and to achieve a cost which is smaller than that of the currently used moulded metal sheet or moulded aluminium wheels.

Description

La présente invention a pour objet une roue à jante d'une seule pièce, à structure composite ou non, assembles par sertissage, destinée en particulier maiq non exclusivement à être montée sur une automobile. The present invention relates to a rim wheel in one piece, with a composite structure or not, assembled by crimping, intended in particular may not exclusively be mounted on an automobile.

Habituellement, les roues non moulées sont composées d'un disque (ou voile) embotté au-dessous du creux de jante et assemblé par soudure ou rivetage sur celle-ci, notamment dans le cas des roues à jante creuse destinées à recevoir des bandages pneumatiques avec ou sans chambre. Dans ce cas, le disque et la jante sont généralement réalisés dans le même matériau, le plus souvent en tale d'acier ou d'aluminium. Usually, the non-molded wheels are composed of a disc (or veil) swathed below the rim hollow and assembled by welding or riveting thereon, in particular in the case of hollow rim wheels intended to receive pneumatic tires. with or without bedroom. In this case, the disc and the rim are generally made of the same material, most often in steel or aluminum sheet.

Ce type de roue se compare aux roues réalisées entièrement en alliage lé- ger, moulé ou forgé, ou en plastique moulé, armé ou non de fibre de verre ou de carbone. Ces roues moulées ou forgées permettent d'obtenir des gains de poids et/ou des possibilités de style irréalisables avec la tôle emboutie. This type of wheel is compared to wheels made entirely of light alloy, molded or forged, or of molded plastic, reinforced or not with fiberglass or carbon. These cast or forged wheels allow weight savings and / or styling possibilities that cannot be achieved with stamped sheet metal.

Leur inconvénient est un prix de revient très supérieur aux roues en tôle d'acier, même agrémentées d'un enjoliveur.Their disadvantage is a cost price much higher than steel sheet wheels, even with a hubcap.

Afin de réduire le coût de ces roues moulées ou forgées, la jante est remplacée par de la tôle d'acier bon marché, éventuellement de la tôle d'aluminium ou de tout autre matériau approprié, cette jante étant assembles sur le voile par sertissage, notamment par magnétoformage. On conserve ainsi l'aspect de la roue moulée tandis que le coût de l'assemblage se trouve réduit par l'absence de boulonnage, rivetage, soudure ou autre procédé souvent difficile å utiliser avec des matériaux différents comme l'acier et l'aluminium. In order to reduce the cost of these cast or forged wheels, the rim is replaced by inexpensive steel sheet, possibly aluminum sheet or any other suitable material, this rim being assembled on the web by crimping, in particular by magnetoforming. This preserves the appearance of the molded wheel while the cost of assembly is reduced by the absence of bolting, riveting, welding or other process often difficult to use with different materials such as steel and aluminum. .

La Figure 1 représente la demi-coupe d'une roue tôle utilisée couramment. Figure 1 shows the half section of a sheet metal wheel commonly used.

Elle comprend une jante 1 avec son creux de jante 12 et son diamètre d'embo;- tage 13 où est assemblé le disque 2 par soudure ou rivetage. L'encombrement des freins est représenté par 11.It comprises a rim 1 with its rim recess 12 and its fitting diameter; - stage 13 where the disc 2 is assembled by welding or riveting. The size of the brakes is represented by 11.

La Figure 2 représente pour une roue composite le principe de la présente invention. La jante en tôle 1 avec son creux de jante 12 est assemblée sur le voile 2, réalisé par exemple en alliage léger moulé ou forgé, ou en plastique moulé, par sertissage autour de la forme 6, ce sertissage étant obtenu par ma gnétoformage ou autre procédé similaire. La jante 1 présente avant sertissage le profil extérieur représenté par la Fig.2a, notamment une partie cylindrique 3 où vient stembotter le disque 2, en appui sur la face 5 et centré sur le diamètre 4. Après sertissage, la jante prend la forme indiquée sur la Fig.2, notamment le hump 7. Le profil de jante est complété par une pièce rapportée 8 sur laquelle vient s'appuyer le talon du pneumatique.L'entraînement au couple se fait par des logements 9 pratiqués dans le voile 2, par exemple comme représenté sur la Fig.2, que la tôle de la jante vient complémentariser en 10 lors du sertissage. Ces logements peuvent être prévus ailleurs sur le voile 2, ou remplacés par des pièces rapportées : pions, vis, etc... traversant
la jante 1 et le voile 2 en un endroit approprié. (voir figure 5)
Le sertissage est représenté sur la Figure 2 au niveau du hump 7. Une tel
le opération peut être réalisée ailleurs sur la jante, notamment sous le creux
de jante 12, ou sous le bord de jante 14. Dans ce cas, la jante de départ a
vant sertissage comporte son profil terminé au niveau du seat extérieur. Figure 2 shows for a composite wheel the principle of the present invention. The sheet metal rim 1 with its rim recess 12 is assembled on the web 2, produced for example from molded or forged light alloy, or from molded plastic, by crimping around shape 6, this crimping being obtained by my gnoforming or other similar process. The rim 1 has, before crimping, the external profile represented by FIG. 2a, in particular a cylindrical part 3 in which the disc 2 comes to rest, bearing on the face 5 and centered on the diameter 4. After crimping, the rim takes the form indicated in FIG. 2, in particular the hump 7. The rim profile is completed by an insert 8 on which the tire bead rests. The torque drive is done by housings 9 made in the web 2, for example as shown in Fig.2, that the sheet of the rim comes to complement at 10 during crimping. These housings can be provided elsewhere on the web 2, or replaced by inserts: pins, screws, etc.
rim 1 and web 2 in a suitable location. (see figure 5)
The crimping is shown in Figure 2 at the hump 7. Such a
the operation can be carried out elsewhere on the rim, in particular under the hollow
rim 12, or under the rim edge 14. In this case, the starting rim has
vant crimping has its finished profile at the outer seat.

La Figure 3 représente le même principe d'assemblage que la Figure 2, mais
dans ce cas le voile est en tôle emboutie, par exemple en acier. On retrouve
le hump 7 obtenu au sertissage sur la forme 6 issue d'emboûtissage sur le voi
le 2, suivant le principe de la Figure 2a. On retrouve également la pièce
complémentaire 8, généralement en élastomère, logée sous le talon du pneuma
tique et les emboûtis 9 dans le voile 2 complementarises par les formes 10 de
la jante lors du sertissage. Une partie 15 peut éventuellement être obtenue
en contre dépouille lors de l'emboutissage du voile 2 pour l'accrochage d'en
joliveurs.Figure 3 shows the same assembly principle as Figure 2, but
in this case the veil is made of stamped sheet metal, for example steel. We find
the hump 7 obtained by crimping on the form 6 after stamping on the track
2, according to the principle of Figure 2a. We also find the room
complementary 8, generally made of elastomer, housed under the heel of the pneuma
tick and deep-drawn 9 in the veil 2 complementarises by the forms 10 of
the rim during crimping. Part 15 can optionally be obtained
undercut during stamping of the web 2 for the attachment of
trimmers.

La Figure 4 illustre le même principe mais avec un sertissage sous le bord
de jante 14. La jante au départ présente la forme illustrée en 4a ; le voile
est centré en 16, en appui sur 17 et comporte les logements 9 issus d'emboû-
tissage. Ce type de construction permet d'obtenir une roue aérodynamique sans
artifice supplémentaire et le coût qui en résulterait.Figure 4 illustrates the same principle but with a crimp under the edge
rim 14. The rim at the start has the shape illustrated in 4a; the veil
is centered in 16, resting on 17 and includes the housings 9 coming from emboû-
weaving. This type of construction makes it possible to obtain an aerodynamic wheel without
additional device and the resulting cost.

Dans tous les cas de figure représentés, on obtient une place supplémen
taire sous le creux de jante pour les freins par la suppression de l'emboi-
tage du disque ou de ltépaisseur de métal dans le cas des roues moulées.In all the cases represented, one obtains an additional place
keep quiet under the rim hollow for the brakes by eliminating the problem
disk or metal thickness in the case of cast wheels.

Il va de soi que des modifications peuvent être apportées aux modes de réa
lisation qui viennent d'être décrits, notamment par substitution de moyens
techniques équivalents, sans sortir pour cela du cadre de la présente inven
tion.It goes without saying that modifications can be made to the reaction modes.
