Description

PORTE-MOYEU POUR VEHICULE AUTOMOBILE, COMPRENANT UN SUPPORT RELIE AU CHASSIS DU VEHICULE, ET UN AXE LIE A CE SUPPORT La présente invention concerne un porte-moyeu pour roue d'un véhicule automobile, ainsi qu'un véhicule automobile équipé de telles porte-moyeux. Les véhicules automobiles comportent généralement un train arrière lié à la caisse du véhicule, comprenant des bras de suspension recevant chacun un porte-moyeu. Chaque porte-moyeu comporte un axe de roue comprenant des roulements, qui supportent et guident le moyeu de la roue. Pour certains véhicules réalisés notamment en petites séries, on souhaite utiliser des plateformes communes pour réduire les coûts d'études et d'industrialisation. On peut notamment utiliser un train arrière commun comportant les mêmes porte-moyeux, pour réaliser des gammes de véhicules comprenant des voies arrière, ou distance transversale entre les plans médians des roues arrière, qui soient différentes. Ces voies arrière différentes peuvent correspondre en particulier à des impératifs techniques, ou à des contraintes liées au style du véhicule. Il est connu notamment par le document FR-1519640, de disposer sur un arbre de roue supporté par un essieu et entraîné par le moteur, un moyeu de roue qui peut se déplacer axialement sur son arbre, pour réaliser un réglable de l'écartement des roues. Le moyeu est bloqué ensuite sur l'arbre par un système de cône serré par des vis. Cette solution a notamment pour inconvénient de modifier le déport latéral de la roue par rapport aux roulements qui la supportent, ce qui change la charge sur ces roulements. Une autre solution connue consiste à interposer axialement entre le bras de suspension et le porte-moyeu, une entretoise qui écarte ce porte-moyeu de l'axe du véhicule. De cette manière, les roulements sont déplacés en même temps que la roue supportée, et le déport transversal de cette roue par rapport aux roulements n'est pas modifié. The present invention relates to a hub carrier for a wheel of a motor vehicle, as well as to a motor vehicle equipped with such carriers. The invention relates to a wheel hub carrier for a motor vehicle, and to a motor vehicle equipped with such carriers. hubs. Motor vehicles generally comprise a rear axle linked to the vehicle body, comprising suspension arms each receiving a hub carrier. Each hub carrier has a wheel axle including bearings, which support and guide the hub of the wheel. For some vehicles made especially in small series, it is desired to use common platforms to reduce the costs of studies and industrialization. In particular, it is possible to use a common rear axle comprising the same hub carriers, to produce ranges of vehicles comprising rear tracks, or transverse distance between the median planes of the rear wheels, which are different. These different rear tracks may correspond in particular to technical requirements, or constraints related to the style of the vehicle. It is known in particular from the document FR-1519640, to have on a wheel shaft supported by an axle and driven by the motor, a wheel hub which can move axially on its shaft, to achieve an adjustable distance of the wheels. wheels. The hub is then locked on the shaft by a cone system tightened by screws. This solution has the particular disadvantage of modifying the lateral offset of the wheel relative to the bearings that support it, which changes the load on these bearings. Another known solution is to interpose axially between the suspension arm and the hub carrier, a spacer that separates the hub carrier from the axis of the vehicle. In this way, the bearings are moved at the same time as the wheel supported, and the transverse offset of this wheel relative to the bearings is not changed.

Il est alors nécessaire de développer une nouvelle entretoise pour chaque modification de l'écartement des roues, ce qui oblige à gérer un nombre de pièces plus important. La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure, et de proposer un porte-moyeu comportant un moyen simple et économique permettant de modifier l'écartement des roues. Elle propose à cet effet un porte-moyeu en particulier pour véhicule automobile, comprenant un support relié au châssis du véhicule, et un axe de roue lié à ce support, recevant des roulements de guidage d'une roue, caractérisé en ce que le support comporte de plus un guidage axial permettant un déplacement de l'axe de roue par rapport à ce support, et un moyen de blocage de cet axe de roue sur le support. Un avantage du porte-moyeu selon l'invention, est qu'en faisant coulisser l'axe de roue sur le support, puis en assurant ensuite un blocage de cet axe grâce au moyen de blocage, on peut sans composant additionnel, régler la voie du véhicule. De plus le porte-moyeu selon l'invention peut comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles. It is then necessary to develop a new spacer for each change of the wheel spacing, which requires managing a larger number of parts. The present invention is intended to avoid these disadvantages of the prior art, and to provide a hub carrier comprising a simple and economical means for changing the spacing of the wheels. To this end, it proposes a hub carrier, in particular for a motor vehicle, comprising a support connected to the chassis of the vehicle, and a wheel axle connected to this support, receiving guide bearings from a wheel, characterized in that the support further comprises an axial guide allowing a displacement of the wheel axle relative to this support, and a locking means of this wheel axle on the support. An advantage of the hub carrier according to the invention is that by sliding the wheel axle on the support, and then then ensuring a locking of this axis through the locking means, one can without additional component, adjust the way of the vehicle. In addition, the hub carrier according to the invention can comprise one or more of the following characteristics, which can be combined with one another.

Avantageusement, le support comprend un alésage centré suivant l'axe de la roue. Le support peut comprendre une partie ayant sensiblement la forme d'une plaque disposée suivant un plan transversal à l'axe de la roue, et une partie tubulaire axiale comportant l'alésage. Advantageously, the support comprises a bore centered along the axis of the wheel. The support may comprise a portion having substantially the shape of a plate disposed in a plane transverse to the axis of the wheel, and an axial tubular portion having the bore.

Avantageusement, l'alésage comprend un taraudage dans lequel vient se visser un filetage de l'axe de roue. L'axe de roue peut être étagé, et comporter successivement en partant de l'intérieur du véhicule, un épaulement d'un diamètre supérieur à celui de l'alésage du support, le filetage, et une partie d'un diamètre réduit recevant les roulements. Advantageously, the bore comprises a thread in which is screwed a thread of the wheel axle. The wheel axle may be staggered, and comprise successively from the inside of the vehicle, a shoulder of a diameter greater than that of the bore of the support, the thread, and a portion of a reduced diameter receiving the bearings.

L'extrémité de l'axe de roue tournée vers l'intérieur du véhicule, peut comporter une empreinte pouvant recevoir une clé pour visser ou dévisser cet axe dans l'alésage du support. Suivant un mode de réalisation, le moyen de blocage comporte une goupille qui est emmanchée dans des perçages du support et de l'axe de roue. Avantageusement, la goupille est disposée suivant un diamètre, et traverse de part en part la partie tubulaire ainsi que l'axe de roue. L'invention a aussi pour objet un véhicule automobile, comprenant un porte-moyeu comportant un support relié au châssis du véhicule, et un axe fixé à ce support, recevant des roulements de guidage d'une roue, ce porte-moyeu comportant de plus l'une quelconque des caractéristiques précédentes. 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 : - la figure 1 présente en perspective un porte-moyeu fixé sur un train arrière, comprenant une entretoise de réglage de l'écartement de la roue selon l'art antérieur ; - la figure 2 présente en perspective un porte-moyeu selon l'invention ; - les figures 3 et 4 présentent en coupe axiale, des vues de ce porte-moyeu dont l'axe est placé suivant deux positions axiales extrêmes. La figure 1 présente un train arrière 1 comportant un bras de suspension 2 disposé longitudinalement sur le côté du véhicule. L'avant du bras de suspension 2 comporte une articulation 4 fixée à la caisse du véhicule, dont l'axe est disposé sensiblement transversalement. Les deux bras de suspension 2 sont reliés entre eux par une traverse déformable 6, qui comporte une élasticité en torsion pour permettre un débattement indépendant des deux roues arrière. The end of the wheel axle facing the interior of the vehicle, may include a fingerprint can receive a key to screw or unscrew this axis in the bore of the support. According to one embodiment, the locking means comprises a pin which is fitted into bores of the support and the wheel axle. Advantageously, the pin is arranged in a diameter, and passes right through the tubular portion and the wheel axle. The invention also relates to a motor vehicle, comprising a hub carrier having a support connected to the chassis of the vehicle, and an axis fixed to the support, receiving guide bearings of a wheel, the hub carrier further comprising any of the foregoing features. 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 accompanying drawings, in which: FIG. hub fixed on a rear axle, comprising a wheel spacing adjustment spacer according to the prior art; - Figure 2 shows in perspective a hub carrier according to the invention; - Figures 3 and 4 show in axial section, views of the hub carrier whose axis is placed in two extreme axial positions. Figure 1 shows a rear axle 1 having a suspension arm 2 disposed longitudinally on the side of the vehicle. The front of the suspension arm 2 comprises a hinge 4 attached to the vehicle body, whose axis is arranged substantially transversely. The two suspension arms 2 are interconnected by a deformable cross member 6, which comprises a torsional elasticity to allow an independent movement of the two rear wheels.

La partie arrière du bras de suspension 2 comporte un réceptacle 8 recevant la base d'un ressort hélicoïdal de suspension non représenté, et une tôle 10 verticale, disposée suivant un plan sensiblement perpendiculaire à un axe transversal, qui reçoit un porte-moyeu 12 de roue Le porte-moyeu 12 comporte un support formant une plaque, supportant un axe de roue perpendiculaire 16 qui reçoit un roulement de roue 18. Le roulement 18 reçoit sur sa bague extérieure, un moyeu 22 comportant un disque de frein 20, et des moyens de fixation de la jante d'une roue non représentée. Une entretoise plate 14 formée dans un profilé en alliage d'aluminium, est interposée entre le support du porte-moyeu 12, et la tôle 10 du bras de suspension 2. L'entretoise 14 comporte des perçages axiaux réalisés dans le profilé, qui reçoivent des vis de serrage axiales permettant de serrer en même temps le support 12 et cette entretoise, sur le bras de suspension 2. Pour ajuster la voie du train arrière 1, il faut prévoir des entretoises 14 ainsi que des vis de serrage, de différentes longueurs. Cela nécessite des études spécifiques pour chaque train arrière, ainsi qu'une gestion de différents composants qui est onéreuse. Les figures 2 à 4 présentent un porte-moyeu 30 comprenant un support 32 formant une plaque disposée suivant un plan sensiblement perpendiculaire à un axe transversal, qui comporte une partie tubulaire axiale 34 centrée suivant l'axe de la roue. La plaque du support 32 comporte une série de perçages axiaux 46 recevant des vis de fixation, pour un serrage direct de cette plaque sur la tôle verticale 10 du train arrière 1, qui est identique à celui selon l'art antérieur présenté précédemment. The rear part of the suspension arm 2 comprises a receptacle 8 receiving the base of a helical suspension spring not shown, and a vertical plate 10, arranged in a plane substantially perpendicular to a transverse axis, which receives a hub carrier 12 of The hub carrier 12 comprises a support forming a plate, supporting a perpendicular wheel axle 16 which receives a wheel bearing 18. The bearing 18 receives on its outer ring, a hub 22 having a brake disc 20, and means fastening the rim of a wheel not shown. A flat spacer 14 formed in an aluminum alloy profile, is interposed between the support of the hub carrier 12, and the sheet 10 of the suspension arm 2. The spacer 14 has axial bores made in the profile, which receive axial clamping screws for simultaneously clamping the support 12 and this spacer on the suspension arm 2. To adjust the way of the rear axle 1, it is necessary to provide spacers 14 and clamping screws, of different lengths. . This requires specific studies for each rear axle, as well as a management of different components that is expensive. Figures 2 to 4 show a hub carrier 30 comprising a support 32 forming a plate disposed in a plane substantially perpendicular to a transverse axis, which comprises an axial tubular portion 34 centered along the axis of the wheel. The support plate 32 comprises a series of axial bores 46 receiving fixing screws, for a direct clamping of this plate on the vertical plate 10 of the rear axle 1, which is identical to that according to the prior art presented above.

La partie tubulaire 34 reçoit dans son alésage comportant un taraudage, un axe de roue 44 étagé comprenant successivement en partant de l'intérieur du véhicule, un épaulement 36 d'un diamètre supérieur à celui de l'alésage, un filetage 38 qui se visse dans le taraudage, une partie lisse d'un diamètre réduit recevant le roulement de roue 18, et à nouveau une partie filetée 42 recevant un écrou de serrage de ce roulement. The tubular portion 34 receives in its bore having a thread, a stepped wheel axis 44 comprising successively starting from the inside of the vehicle, a shoulder 36 of a diameter greater than that of the bore, a thread 38 which is screwed in the tapping, a smooth portion of a reduced diameter receiving the wheel bearing 18, and again a threaded portion 42 receiving a clamping nut of the bearing.

L'extrémité de l'axe 44 tournée vers le côté intérieur du véhicule, comporte une empreinte hexagonale creuse 40 pouvant recevoir une clé pour visser ou dévisser cet axe dans la partie tubulaire 34. Le filetage 38 de l'axe 44 est environ deux fois plus long que la partie tubulaire 34 du support 32, on peut ainsi en exerçant une rotation de l'axe 44 avec la clé, facilement déplacer cet axe et régler sa position transversale, sur une course qui peut aller par exemple jusqu'à 50 mm. En variante, le guidage axial de l'axe 44 constitué par le filetage 38 coopérant avec le taraudage de la partie tubulaire 34, pourrait comprendre d'autres moyens comme un guidage lisse de l'axe dans l'alésage du porte-moyeu 32. Une fois l'axe 44 mis en place dans la position souhaitée par vissage, une goupille radiale 50 est emmanchée dans des perçages débouchant suivant un diamètre, qui traversent de part en part la partie tubulaire 34 ainsi que l'axe. Cette goupille 50 qui est montée serrée, assure ainsi un blocage de l'axe 44 qui ne peut plus tourner, cet axe est maintenu définitivement en position. De plus cette goupille 50 serrée, annule des petits jeux qui pourraient rester entre le filetage de l'axe 44, et le taraudage du support 32. The end of the axis 44 facing the inside of the vehicle, has a hollow hexagonal recess 40 can receive a key for screwing or unscrew this axis in the tubular portion 34. The thread 38 of the axis 44 is about twice longer than the tubular portion 34 of the support 32, it is thus possible by exerting a rotation of the axis 44 with the key, easily move this axis and adjust its transverse position, on a stroke that can go for example up to 50 mm . As a variant, the axial guidance of the axis 44 constituted by the threading 38 cooperating with the tapping of the tubular portion 34, could comprise other means such as a smooth guide of the axis in the bore of the hub carrier 32. Once the axis 44 is placed in the desired position by screwing, a radial pin 50 is fitted into holes opening out in a diameter, which pass right through the tubular portion 34 and the axis. This pin 50 which is mounted tightly, thus ensuring a locking of the axis 44 which can no longer rotate, this axis is permanently maintained in position. In addition this pin 50 tight, cancels small clearances that could remain between the thread of the axis 44, and the tapping of the support 32.

En variante d'autres moyens de blocage de l'axe 44 pourraient être utilisés, comme par exemple une goupille disposée tangentiellement, ou une vis de serrage tangentielle qui serrerait la partie tubulaire 34 sur cet axe. La figure 3 représente une position de l'axe 44 complètement rentrée vers l'intérieur du véhicule, la figure 4 une position complètement sortie vers l'extérieur du véhicule, cet axe comportant deux perçages suivant des diamètres, pour recevoir la goupille 50 dans ces deux positions. On réalise ainsi un moyen de réglage simple, ne nécessitant pas de composant additionnel, pour régler la voie du train arrière du véhicule. L'ensemble comprenant la roue, le dispositif de freinage qui peut comporter un disque ou un tambour, et les roulements, est déplacé en même temps, sa géométrie n'étant pas modifiée. Alternatively other locking means of the axis 44 could be used, such as a tangentially arranged pin, or a tangential clamping screw that would tighten the tubular portion 34 on this axis. FIG. 3 shows a position of the axle 44 fully retracted towards the inside of the vehicle, FIG. 4 a position completely extended towards the outside of the vehicle, this axle having two holes in diameters for receiving the pin 50 in these two positions. This provides a simple adjustment means, requiring no additional component, to adjust the path of the rear axle of the vehicle. The assembly comprising the wheel, the braking device which may comprise a disc or a drum, and the bearings, is moved at the same time, its geometry being not modified.

Le réglage de la voie peut se faire rapidement de manière très flexible, lors de la préparation du train arrière, ou au dernier moment sur la chaîne d'assemblage du véhicule, suivant la version de véhicule réalisée. En variante et pour sensiblement un même coût, on pourrait avoir plus de deux positions de réglage, avec des perçages supplémentaires dans l'axe 44 entre les deux positions d'extrémité, pour bloquer ces différentes positions. Ces perçages suivant un diamètre peuvent notamment être réalisés dans différents plans transversaux. On notera que le moyen de réglage suivant l'invention demande seulement une modification du porte-moyeu 30, et peut s'adapter sur un bras de suspension arrière 2 réalisé suivant l'art antérieur, sans modifier ce bras. Track adjustment can be done quickly and flexibly, when preparing the rear axle, or at the last moment on the vehicle assembly line, depending on the version of the vehicle. Alternatively and for substantially the same cost, there could be more than two adjustment positions, with additional holes in the axis 44 between the two end positions to block these different positions. These holes according to a diameter can in particular be made in different transverse planes.
