Description

SYSTEME DE FIXATION ANTIVOL POUR ENJOLIVEUR DE ROUE COMPRENANT UN JONC OUVERT ELASTIQUE  ANTI-THEFT FASTENING SYSTEM FOR A WHEEL SHEET COMPRISING AN ELASTIC OPEN JUNK
La présente invention concerne un système de fixation d'un enjoliveur de roue de véhicule automobile, ainsi qu'un véhicule automobile équipé d'enjoliveurs maintenus par de tels systèmes. The present invention relates to a fastening system for a wheel trim of a motor vehicle, and a motor vehicle equipped with hubcaps maintained by such systems.
Certaines roues de véhicules automobiles reçoivent sur la face extérieure de la jante un enjoliveur assurant une esthétique et une finition particulière, notamment en cachant les écrous de roue, ou en recouvrant les ouvertures de la jante pratiquées pour permettre un refroidissement du frein.  Some motor vehicle wheels receive on the outer face of the rim a trim for a particular aesthetic and finish, including hiding the wheel nuts, or covering the openings of the rim made to allow cooling of the brake.
On dispose généralement ces enjoliveurs sur des jantes réalisées en tôle d'acier, et aussi sur certaines jantes en aluminium. On peut en particulier à partir d'une même jante standard, donner des aspects différents suivant le type de véhicule à assembler.  These hubcaps are generally available on rims made of sheet steel, and also on some aluminum wheels. One can in particular from the same standard rim, give different aspects depending on the type of vehicle to assemble.
Un type d'enjoliveur connu moulé en matière plastique, comporte sur sa face intérieure dirigée vers la jante, près de son périmètre, une succession de pattes élastiques formant un cercle comprenant des bossages tournés radialement vers l'extérieur. Un jonc métallique circulaire engagé à l'intérieur de ces pattes, tend à les écarter vers l'extérieur.  A known type of hubcap molded plastic, has on its inner face directed towards the rim, near its perimeter, a succession of elastic tabs forming a circle comprising bosses turned radially outwardly. A circular metal ring engaged inside these legs, tends to spread outward.
Lors de la mise en place de l'enjoliveur sur la jante en pressant axialement dessus, les pattes élastiques sont d'abord resserrées vers l'axe de la roue pour permettre aux bossages de passer un épaulement, puis ces bossages s'ajustent dans une rainure circulaire de la jante, le jonc métallique les pressant de manière permanente pour les maintenir dans cette rainure.  When placing the hubcap on the rim by pressing axially above, the resilient tabs are first tightened towards the axis of the wheel to allow the bosses to pass a shoulder, then these bosses fit into a circular groove of the rim, the metal ring pressing them permanently to hold them in this groove.
Un problème qui se pose avec ce type d'assemblage est qu'il faut prévoir à la fois une souplesse suffisante des pattes pour permettre un montage et un démontage assez facile de l'enjoliveur, et un maintien important évitant de le perdre en route. De plus il est simple de les voler en tirant dessus.  A problem that arises with this type of assembly is that it is necessary to provide both sufficient flexibility of the tabs to allow mounting and easy disassembly of the hubcap, and a significant maintenance avoiding losing it en route. Moreover it is simple to fly them by shooting on them.
Un autre type d'enjoliveur connu comporte une forme tubulaire alignée sur chaque vis de fixation de la roue, comprenant une extrémité se resserrant après la tête de vis pour assurer un clipsage. Toutefois on a aussi des difficultés pour réaliser à la fois un maintien efficace, et une facilité de montage et de démontage. De plus le vol est simple à pratiquer. Another type of hubcap known comprises a tubular shape aligned on each wheel fixing screw, comprising an end tightening after the screw head to ensure clipping. However, there are also difficulties in achieving both effective maintenance, and ease of assembly and disassembly. Moreover the flight is simple to practice.
Un autre type d'enjoliveur connu comporte un perçage central recevant une vis qui est serrée sur un écrou de la jante. Il faut alors manœuvrer la vis sur un certain nombre de tours pour assurer le montage ou le démontage, ce qui est relativement long. De plus un desserrage de cette vis avec les vibrations du roulage peut arriver, et on peut perdre la vis lors du démontage.  Another type of known hubcap comprises a central bore receiving a screw which is tightened on a rim nut. It is then necessary to maneuver the screw on a certain number of turns to ensure the assembly or the disassembly, which is relatively long. Moreover a loosening of this screw with the vibrations of the rolling can happen, and one can lose the screw during disassembly.
Un autre type d'enjoliveur connu, présenté notamment par le document DE-C2-3505145, comporte un verrou central actionné par une clé, comprenant un loquet qui est introduit dans une ouverture de la jante de forme radiale, comprenant une position angulaire définie. Par une manœuvre de la clé, le loquet est tourné de manière à venir s'accrocher derrière la jante, sur le côté de l'ouverture radiale.  Another type of known hubcap, presented in particular by DE-C2-3505145, comprises a central latch actuated by a key, comprising a latch which is introduced into a radially shaped opening of the rim, comprising a defined angular position. By a maneuver of the key, the latch is turned so as to hang behind the rim, on the side of the radial opening.
Ce type de fixation de l'enjoliveur est relativement complexe à réaliser. This type of attachment of the hubcap is relatively complex to achieve.
De plus il est difficile d'assurer par la rotation de la serrure un serrage du loquet sur la jante, donnant une absence de jeu dans la fixation de l'enjoliveur. Moreover it is difficult to ensure by the rotation of the lock a tightening of the latch on the rim, giving an absence of play in the fastening of the hubcap.
Par ailleurs il est important de disposer d'un système de fixation de l'enjoliveur qui soit simple, facile et rapide à installer, tout en ne risquant pas de perdre d'éléments, que ce soit lors du démontage de l'enjoliveur ou du roulage du véhicule.  Furthermore it is important to have a fastening system of the hubcap that is simple, easy and quick to install, while not risking any loss of elements, whether during disassembly of the hubcap or the driving the vehicle.
La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.  The present invention is intended to avoid these disadvantages of the prior art.
Elle propose à cet effet un système de fixation pour enjoliveur de roue de véhicule automobile, prévu pour maintenir l'enjoliveur comportant un perçage central, serré sur la face extérieure de la jante disposant d'un alésage central, remarquable en ce qu'il comporte un bouchon présentant sur sa face extérieure une empreinte codée accessible à un outil spécifique pour l'entraîner en rotation, une rondelle maintenue axialement à l'intérieur du bouchon, disposant de moyens de blocage angulaire sur la jante, et un jonc ouvert élastique réalisant une expansion radiale pour s'ajuster dans une gorge intérieure de l'alésage central de la jante, le bouchon et la rondelle présentant de plus des formes d'accrochage des extrémités du jonc pour entraîner par la rotation du bouchon un resserrage radial de ce jonc. It proposes for this purpose a fastening system for wheel trim of a motor vehicle, provided to maintain the hubcap comprising a central bore, tight on the outer face of the rim having a central bore, remarkable in that it comprises a plug having on its outer face a coded fingerprint accessible to a specific tool to drive it in rotation, a washer held axially inside the plug, having angular locking means on the rim, and a resilient open ring producing a radial expansion to fit into an inner groove of the central bore of the rim, the cap and the washer having further forms of attachment of the ends of the ring to cause by the rotation of the plug a retightening radial of this ring.
Un avantage de ce système de fixation est que de manière simple, par une rotation du bouchon dans un sens avec l'outil correspondant, on resserre radialement le jonc ce qui permet de le dégager de la gorge intérieure. De plus le système de fixation conservant tous ses éléments reliés entre eux, on ne peut pas perdre d'éléments après un démontage de l'enjoliveur.  An advantage of this fastening system is that in a simple manner, by a rotation of the plug in one direction with the corresponding tool, the ring is tightened radially which makes it possible to disengage it from the internal groove. In addition the fastening system retaining all its interconnected elements, you can not lose items after disassembly of the hubcap.
Par ailleurs seule la face extérieure du bouchon comprenant l'empreinte codée étant accessible, une personne malveillante ne peut pas chercher à démonter une pièce particulière du système de fixation, pour essayer de voler l'enjoliveur ou la roue.  Moreover, only the outer face of the cap comprising the coded footprint being accessible, a malicious person can not seek to disassemble a particular part of the fastening system, to try to steal the hubcap or the wheel.
Le système de fixation selon l'invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.  The fastening system according to the invention may further comprise one or more of the following features, which may be combined with each other.
Avantageusement, le jonc ouvert est disposé axialement entre le bouchon et la rondelle.  Advantageously, the open ring is disposed axially between the plug and the washer.
Dans ce cas, la rondelle peut être centrée sur un téton du bouchon. De plus, la rondelle est avantageusement calée axialement sur le téton par un circlips.  In this case, the washer may be centered on a plug nipple. In addition, the washer is advantageously wedged axially on the stud by a circlip.
En particulier, le jonc peut être disposé autour d'un épaulement axial de la rondelle.  In particular, the ring may be arranged around an axial shoulder of the washer.
Avantageusement, l'épaulement axial comporte un évidement suivant un secteur angulaire, recevant des retours vers le centre des extrémités du jonc.  Advantageously, the axial shoulder comprises a recess along an angular sector, receiving returns towards the center of the ends of the rod.
Avantageusement, le jonc comporte un grand retour de manœuvre vers le centre, qui est engagé dans une rainure du bouchon sensiblement diamétrale.  Advantageously, the ring has a large return maneuver towards the center, which is engaged in a groove of the substantially diametral plug.
Avantageusement, les moyens de blocage angulaire de la rondelle sur la jante comportent des tenons axiaux dirigés vers le côté intérieur. Avantageusement, l'empreinte codée est directement formée dans la matière du bouchon. Advantageously, the angular locking means of the washer on the rim comprise axial tenons directed towards the inner side. Advantageously, the coded imprint is directly formed in the plug material.
L'invention a aussi pour objet un véhicule automobile comportant des roues équipées d'enjoliveurs maintenus par un système de fixation comportant l'une quelconque des caractéristiques précédentes.  The invention also relates to a motor vehicle having wheels equipped with hubcaps held by a fastening system having any of the preceding features.
L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d'exemple, en référence aux dessins annexés dans lesquels :  The invention will be better understood and other features and advantages will appear more clearly on reading the following description given by way of example, with reference to the appended drawings in which:
- la figure 1 présente en coupe axiale un système de fixation selon l'invention maintenant un enjoliveur sur une jante en alliage d'aluminium ; et - Figure 1 shows in axial section a fastening system according to the invention now a hubcap on an aluminum alloy rim; and
- les figures 2 et 3 sont deux vue éclatées de ce système de fixation, présentant respectivement le côté extérieur et le côté intérieur. - Figures 2 and 3 are two exploded view of this fastening system, having respectively the outer side and the inner side.
La figure 1 présente un moyeu de roue de véhicule 2, guidé en rotation suivant l'axe principal A par des roulements 6 fixés dans un porte-moyeu 4 maintenu par la suspension du véhicule. Un arbre de roue 8 traversant le moyeu 2, est maintenu axialement serré par un écrou 10 fixé à son extrémité extérieure.  Figure 1 shows a vehicle wheel hub 2, guided in rotation along the main axis A by bearings 6 fixed in a hub carrier 4 held by the suspension of the vehicle. A wheel shaft 8 passing through the hub 2 is held axially tight by a nut 10 fixed at its outer end.
Le moyeu 2 comporte du côté extérieur, un centrage 12 recevant successivement la partie centrale plane d'un disque de frein 14, et un alésage de centrage d'une jante en aluminium 16. La jante en aluminium 16 et le disque de frein 14 sont maintenus serrés par une succession de vis non représentées, disposées suivant des axes B répartis autour de l'axe principal A.  The hub 2 comprises on the outer side, a centering 12 successively receiving the flat central portion of a brake disc 14, and a centering bore of an aluminum rim 16. The aluminum rim 16 and the brake disc 14 are held tight by a succession of screws not shown, arranged along B axes distributed around the main axis A.
Un enjoliveur 22 plaqué sur la face extérieure de la jante 16, est maintenu serré sur cette jante par un système de fixation 20 traversant un perçage central de cet enjoliveur, et venant s'ajuster dans un alésage central de la jante 24. Le système de fixation 20 est bloqué axialement par un jonc ouvert 26 qui réalise une expansion radiale dans une gorge circulaire intérieure 28 de l'alésage central 24 de la jante 1 6.  A hubcap 22 plated on the outer face of the rim 16, is held tight on this rim by a fastening system 20 passing through a central bore of this hubcap, and fitting into a central bore of the rim 24. The system of FIG. 20 is fastened axially by an open ring 26 which performs a radial expansion in an inner circular groove 28 of the central bore 24 of the rim 1 6.
Le contour extérieur de l'enjoliveur 22 est en appui sur la jante 16, le système de fixation 20 réalisant une légère déformation axiale élastique de cet enjoliveur vers cette jante afin de maintenir une pression constante sur les appuis qui garantit une absence de jeu, et donc évite une usure ainsi que des bruits lors du roulage du véhicule. The outer contour of the hubcap 22 is supported on the rim 16, the fastening system 20 producing a slight elastic axial deformation of this hubcap to this rim to maintain a constant pressure on the supports which ensures a lack of play, and thus avoids wear and noise during the running of the vehicle.
L'enjoliveur 22 peut être en particulier en matière plastique moulée, ou en tout autre matière comme une tôle en acier ou en aluminium, ou en matériaux composites, de manière à former une protection ainsi qu'une esthétique particulière.  The hubcap 22 may be in particular molded plastic, or any other material such as a steel sheet or aluminum, or composite materials, so as to form a protection and a particular aesthetic.
Les figures 1 , 2 et 3 présentent le système de fixation 20 comprenant successivement en partant du côté extérieur, un bouchon 30, le jonc élastique 26, une rondelle 32 et un circlips annulaire de maintien axial de cette rondelle 34.  FIGS. 1, 2 and 3 show the fastening system 20 successively comprising, starting from the outside, a plug 30, the elastic ring 26, a washer 32 and an annular circlip for axially holding this washer 34.
Le bouchon 30 comporte sur sa face intérieure un épaulement axial de grand diamètre 40, prévu pour recevoir le perçage central de l'enjoliveur 22, puis pour se centrer dans l'alésage central de la jante 24. En particulier le diamètre de l'alésage central 24 peut être d'environ 60mm, ce qui représente une dimension courante pour ce type de roue.  The cap 30 has on its inner face a large diameter axial shoulder 40, designed to receive the central bore of the hubcap 22, then to center in the central bore of the rim 24. In particular the diameter of the bore central 24 can be about 60mm, which is a common dimension for this type of wheel.
Le bouchon 30 comporte ensuite un téton axial de petit diamètre 42 comprenant une rainure annulaire extérieure 44 prévue pour recevoir le circlips 34, ce téton axial présentant une rainure diamétrale 46 sur toute sa longueur.  The plug 30 then comprises a small diameter axial stud 42 comprising an outer annular groove 44 provided for receiving the circlip 34, this axial stud having a diametrical groove 46 along its entire length.
Le jonc 26 formé dans un fil métallique de section circulaire, constitue un cercle ouvert couvrant environ 80 à 90% du périmètre, présentant sur une première extrémité un petit retour de blocage vers le centre 50, et sur la deuxième extrémité un grand retour de manœuvre vers le centre 52 disposé suivant un diamètre, qui est engagé dans la rainure 46 du bouchon 30.  The ring 26 formed in a wire of circular section, constitutes an open circle covering about 80 to 90% of the perimeter, having on a first end a small blocking return towards the center 50, and on the second end a large return of maneuver towards the center 52 arranged in a diameter, which is engaged in the groove 46 of the plug 30.
La rondelle 32 comporte un perçage central ajusté sur le téton axial de petit diamètre 42 du bouchon 30, puis maintenu par le circlips 34 de manière à permettre une rotation libre de cette rondelle.  The washer 32 has a central bore fitted on the small diameter axial stud 42 of the plug 30, and then held by the circlip 34 so as to allow free rotation of this washer.
La partie circulaire du jonc 26 est ajustée autour d'un épaulement axial 54 de la rondelle 32, tourné vers le côté extérieur, comprenant un évidement suivant un secteur angulaire 56, recevant le retour de blocage 50 et le retour de manœuvre 52. Au repos ces deux retours 50, 52 sont ajustés dans l'évidement 56, de manière à limiter l'expansion radiale du jonc 26 suivant un rayon nécessaire pour permettre son engagement dans la gorge intérieure 28 de la jante 16. The circular portion of the ring 26 is fitted around an axial shoulder 54 of the washer 32, turned towards the outer side, comprising a recess along an angular sector 56, receiving the blocking return 50 and the return 52. At rest these two returns 50, 52 are fitted in the recess 56, so as to limit the radial expansion of the rod 26 along a radius necessary to allow its engagement in the inner groove 28 of the rim 16.
La face intérieure de la rondelle 32 comporte quatre tenons 58 dirigés axialement vers le côté intérieur, qui sont engagés chacun dans un creux correspondant de la jante 16 formé au fond de l'alésage central de cette jante 24, de manière à assurer un blocage anti-rotation de cette rondelle.  The inner face of the washer 32 comprises four pins 58 directed axially towards the inner side, which are each engaged in a corresponding recess in the rim 16 formed at the bottom of the central bore of this rim 24, so as to ensure an anti-lock. -rotation of this washer.
Le bouchon 30 comporte sur sa face extérieure un creux cylindrique comprenant au centre une forme 60 directement réalisée dans la matière du bouchon, permettant l'engagement d'une clé, ainsi qu'une flèche 62 tournée vers la gauche, indiquant le sens de rotation de la clé pour permettre un démontage du système de fixation 20.  The cap 30 has on its outer face a cylindrical hollow comprising in the center a shape 60 directly made in the plug material, allowing the engagement of a key, and an arrow 62 turned to the left, indicating the direction of rotation of the key to allow disassembly of the fastening system 20.
La forme permettant l'engagement de la clé 60 présentée ici est hexagonale. Avantageusement cette forme dispose d'un profil particulier adapté pour un embout de démontage spécifique pour ce véhicule, réalisant un antivol. Avantageusement l'embout de démontage est identique pour au moins un écrou de fixation de chaque roue, ce qui permet d'utiliser un seul outillage pour démonter les enjoliveurs 22 et les roues.  The shape allowing the engagement of the key 60 presented here is hexagonal. Advantageously, this form has a particular profile adapted for a specific disassembly tip for this vehicle, providing a lock. Advantageously the disassembly tip is identical for at least one fastening nut of each wheel, which allows the use of a single tool to disassemble the hubcaps 22 and wheels.
Un capuchon 68 comprenant un couvercle extérieur 74, venant fermer le creux du bouchon 30, comporte des bossages radiaux 66 recevant un jonc intérieur 70 qui maintient une pression radiale sur ces bossages, afin de les engager dans une gorge intérieure annulaire 64 de la partie cylindrique de ce creux. On réalise ainsi un clipsage du capuchon 68 sur le bouchon 30 en pressant dessus axialement, un perçage 72 de la face de ce capuchon permettant son retrait en engageant un outil dedans pour tirer sur le capuchon.  A cap 68 comprising an outer cover 74, closing the hollow of the cap 30, comprises radial bosses 66 receiving an inner ring 70 which maintains a radial pressure on these bosses, to engage them in an annular inner groove 64 of the cylindrical portion from this hollow. Thus, the cap 68 is clipped onto the cap 30 by pressing axially on it, a bore 72 of the face of this cap allowing its removal by engaging a tool in it to pull on the cap.
Avantageusement le bouchon 30 et la rondelle 32 sont réalisés par un moulage d'une matière plastique, ce qui permet de produire de manière économique des formes complexes.  Advantageously, the plug 30 and the washer 32 are made by molding a plastic material, which makes it possible to economically produce complex shapes.
Le fonctionnement du système de fixation 20 et le suivant. La mise en place de l'enjoliveur 22 et de son système de fixation 20 se fait simplement après avoir orienté angulairement ce système pour ajuster les tenons 58 dans les creux correspondants de la jante 16, en frappant avec la main ou un maillet sur le bouchon 30 pour resserrer radialement le jonc 26, et l'engager dans la gorge intérieure 28 de l'alésage central 24. Le jonc 26 s'écarte ensuite automatiquement dans cette gorge 28 en effectuant une expansion radiale. The operation of the fastening system 20 and the following. The fitting of the hubcap 22 and its fastening system 20 is done simply after angularly orienting this system to adjust the pins 58 in the corresponding recesses of the rim 16, by striking with the hand or a mallet on the plug 30 to tighten radially rod 26, and engage in the inner groove 28 of the central bore 24. The rod 26 then automatically deviates in this groove 28 by performing a radial expansion.
Pour le retrait du système de fixation 20 et de l'enjoliveur 22, l'opérateur retire le capuchon 68, puis tourne avec l'embout approprié le bouchon 30 dans le sens indiqué par la flèche 62.  For the removal of the fastening system 20 and the hubcap 22, the operator removes the cap 68, then rotates with the appropriate end cap 30 in the direction indicated by the arrow 62.
La rainure diamétrale 46 du bouchon 30 entraîne en rotation le retour de manœuvre 52 alors que le retour de blocage 50 est bloqué en rotation par la rondelle 32, elle-même bloquée par ses tenons 58, ce qui impose un resserrage vers l'axe du jonc 26. Le jonc 26 se dégage ainsi de la gorge intérieure 28 de l'alésage central 24, le système de fixation 30 peut coulisser librement vers l'arrière en tirant dessus.  The diametrical groove 46 of the plug 30 rotates the operating return 52 while the blocking return 50 is locked in rotation by the washer 32, itself blocked by its pins 58, which imposes a tightening towards the axis of the 26. The ring 26 thus disengages from the inner groove 28 of the central bore 24, the fastening system 30 can slide freely backwards by pulling on it.
On obtient ainsi un système de fixation simple et économique, comprenant la forme d'entraînement par une clé 60 directement intégrée dans le bouchon 30, ce qui empêche de la perdre. Le système de fixation facile à mettre en place et à retirer, assure un maintien efficace évitant de perdre l'enjoliveur lors du roulage du véhicule, ainsi qu'une protection efficace contre le vol.  This provides a simple and economical fastening system, including the drive shape by a key 60 directly integrated in the plug 30, which prevents losing it. The easy-to-install and retractable attachment system ensures effective maintenance without losing the hubcap when driving the vehicle, as well as effective protection against theft.
