Description
Montage de roue entrainéeparun joint homocinétique.Wheel mounting driven by a constant velocity joint.
L'invention concerne un montage de roue de véhicule entrainéepar un joint homocinétique dont le palier à roulement possède une bague extérieure à bride de fixation à un support de moyeu de roue et une bague intérieure solidaire du moyeu de roue.The invention relates to a vehicle wheel mounting driven by a constant velocity joint, the rolling bearing has an outer ring with a flange for fixing to a wheel hub support and an inner ring integral with the wheel hub.
Selon la demande de brevet FRA 2 005 9ôi, la bague intérieure du roulement est réunie au moyeu de roue et à l'élément mené du joint tournant homocinétique. Ce type de montage est très délicat à réaliser, car tous les organes doivent être très exactement centrés et fixés les uns aux autres avant d'être réunis de façon inséparable, afin que le bon fonctionnement soit garanti ; des tolérances de fabrication très étroites doivent être en outre observées. Sur les formes de réalisation dans lesquelles la bague intérieure du palier est soudée au corps extérieur du joint, il peut arriver que des étincelles et des projections de soudure endommagent les pistes de roulement du palier.According to patent application FRA 2 005 9oi, the inner ring of the bearing is joined to the wheel hub and to the driven element of the constant velocity joint. This type of assembly is very delicate to carry out, because all the members must be very exactly centered and fixed to each other before being joined inseparably, so that the proper functioning is guaranteed; very close manufacturing tolerances must also be observed. In the embodiments in which the inner ring of the bearing is welded to the outer body of the seal, it may happen that sparks and weld spatter damage the rolling tracks of the bearing.
Selon le brevet FRA 2 408 473, l'élément mené du joint possède une face radiale de raccordement par soudure au moyeu support de la bague intérieure du roulement et une face de butée et d'appui axial de ladite bague.According to patent FRA 2 408 473, the driven element of the seal has a radial face for connection by welding to the support hub of the inner race of the bearing and a stop face and axial support for said race.
Le problème non résolu par ce montage réside dans le fait que l'on ne peut procéder simplement au remplacement du roulement de roue ou de l'élément du joint homocinétique sans détruire certains éléments cons- titutifs de l'ensemble monté. Un autre problème non résolu réside dans le fait que le roulement ne peut constituer un sous-ensemble livré assemblé prêt au montage sur l'élément du joint homocinétique.The problem not solved by this assembly lies in the fact that it is not possible to simply replace the wheel bearing or the element of the constant velocity joint without destroying certain constituent elements of the assembled assembly. Another unresolved problem lies in the fact that the bearing cannot constitute a sub-assembly delivered assembled ready for mounting on the element of the constant velocity joint.
Partant de l'état de la technique précité, l'invention s'est posé le problème de réaliser un moyeu de roue économique grâce à l'utilisation de composants simples et d'usiner l'élément mené du joint homocinétique de telle sorte que l'assemblage du moyeu soit amélioré et simplifié. Starting from the aforementioned state of the art, the invention posed the problem of producing an economical wheel hub thanks to the use of simple components and of machining the driven element of the constant velocity joint so that the 'hub assembly is improved and simplified.
Conformément à l'invention, ce problème est résolu par le fait que l'élément mené du joint homocinétique se prolonge axialement vers le palier à roulement par une queue creuse dont la surface cylindrique constitue une surface de portée d'assemblage avec le moyeu porteur de la roue.According to the invention, this problem is solved by the fact that the driven element of the constant velocity joint extends axially towards the rolling bearing by a hollow tail, the cylindrical surface of which constitutes an assembly bearing surface with the bearing hub. wheel.
L'avantage de ce montage réside dans le fait que l'élément mené du joint homocinétique et le moyeu de la roue peuvent être fabriqués séparément et ne seront réunis qu'après vérification de leur bon fonc tionnement. Son avantage complémentaire réside dans le fait que le moyeu peut être soudé ou assemblé à des éléments menés de joints homocinétiques différents, sans augmentation notable des coûts de fabrication.The advantage of this assembly lies in the fact that the driven element of the constant velocity joint and the hub of the wheel can be manufactured separately and will not be assembled until their proper functioning has been checked. Its additional advantage lies in the fact that the hub can be welded or assembled to driven elements of different constant velocity joints, without appreciable increase in manufacturing costs.
I1 est à remarquer que le palier à roulement peut être séparé ou intégré soit à l'élément mené du joint homocinétique ainsi que l'enseigne l'état de la technique, soit au moyeu de roue. It should be noted that the rolling bearing can be separated or integrated either into the driven element of the constant velocity joint as indicated by the state of the art, or into the wheel hub.
Sur un montage avec palier à roulement séparé, le serrage axial exercé sur la bague intérieure du roulement est assuré par un dispositif d'immobilisation axiale conventionnel de la queue de l'élément du joint homocinétique par rapport au moyeu.On a mounting with a separate rolling bearing, the axial tightening exerted on the inner ring of the bearing is ensured by a conventional axial immobilization device of the tail of the constant velocity joint element relative to the hub.
Sur un montage avec palier à roulement intégré du type dans lequel le moyeu ou l'élément mené du joint homocinétique portent les chemins des corps roulants, la liaison entre le moyeu et l'élément de joint homocinétique peut être réaliseepar soudure ou par assemblage mécanique conventionnel.On an assembly with an integrated rolling bearing of the type in which the hub or the driven element of the constant velocity joint carries the paths of the rolling bodies, the connection between the hub and the constant velocity joint element can be made by welding or by conventional mechanical assembly .
Des exemples de réalisation de l'invention sont représentés schématiquement sur le dessin dont les figures montrent une demi-coupe axiale d'un montage de roue directrice motrice de véhicule automobile.Examples of embodiments of the invention are shown diagrammatically in the drawing, the figures of which show an axial half-section of a drive wheel assembly for a motor vehicle.
La figure 1 décrit un montage de roue à roulement intégré où l'élément mené du joint homocinétique est assemblé par soudure au moyeu porte roue. Figure 1 describes a wheel assembly with integrated bearing where the driven element of the constant velocity joint is assembled by welding to the wheel hub.
La figure 2 décrit un montage de roue à roulement rapporté sur une portée extérieure de l'élément mené du joint homocinétique assemblé par soudure au moyeu porte roue.FIG. 2 describes a mounting of a rolling wheel attached to an outer surface of the driven element of the constant velocity joint assembled by welding to the wheel carrier hub.
La figure 3 décrit un montage de roue à roulement intégré au moyeu.FIG. 3 describes a bearing wheel assembly integrated into the hub.
La figure 4 décrit un montage de roue à roulement rapporté au moyeu.FIG. 4 describes a mounting of a rolling wheel attached to the hub.
Le montage de roue représenté à la figure i comporte essentiellement un moyeu l muni à l'une de ses extrémités d'une bride 2 dont la face extérieure recevant un disque de frein 3 est tournée vers la roue du véhicule non représentée. La face intérieure de la bride 2 se prolonge d'abord radialement vers le corps du moyeu par un épaulement 4 ou butée axiale puis axialement par une portée cylindrique 5 d'assemblage par soudure à l'élément mené 6 d'un joint homocinetique. The wheel assembly shown in FIG. I essentially comprises a hub l provided at one of its ends with a flange 2, the outer face of which receiving a brake disc 3 faces the wheel of the vehicle, not shown. The inner face of the flange 2 extends first radially towards the body of the hub by a shoulder 4 or axial stop, then axially by a cylindrical surface 5 for assembly by welding to the driven element 6 of a constant velocity joint.
L'élément mené 6 du joint homocinétique présente à cet effet une queue creuse 7 qui s'étend vers le palier à roulement 8 jusqutà l'épaule- ment 4 et dont la surface cylindrique alésée interne 9 constitue la surface d'assemblage avec le moyeu l. The driven element 6 of the constant velocity joint has for this purpose a hollow tail 7 which extends towards the rolling bearing 8 up to the shoulder 4 and whose cylindrical internal bored surface 9 constitutes the assembly surface with the hub l.
La bague extérieure fixe Il du palier 8 porte les pistes de roulement des corps roulants 10 et possède une bride de fixation 12 à un support de montage pivotant 13 ainsi que cela est bien connu.The fixed outer ring 11 of the bearing 8 carries the rolling tracks of the rolling bodies 10 and has a fixing flange 12 to a pivoting mounting support 13 as is well known.
Les pistes de roulement des corps 10 intégrées à l'élément 6 suppléent à l'emploi d'une bague intérieure de roulement conventionnelle.The rolling tracks of the bodies 10 integrated into the element 6 replace the use of a conventional inner race ring.
Le montage précité permet la constitution d'un sous-ensemble préassemblé constitué principalement par l'élément 6 du joint homocinétique et par l'ensemble des organes du palier 8.The aforementioned assembly allows the constitution of a pre-assembled sub-assembly constituted mainly by the element 6 of the constant velocity joint and by all the bodies of the bearing 8.
Le montage est complété par l'assemblage du sous-ensemble précité sur le moyeu 1 et sa solidarisation avec le moyeu par un procédé de soudure au rayon laser. On assemble enfin les divers constituants du joint homocinétique. The assembly is completed by assembling the aforementioned sub-assembly on the hub 1 and securing it to the hub by a laser beam welding process. Finally, the various constituents of the constant velocity joint are assembled.
La figure 2- - montre une variante du montage représenté à la figure 1.Figure 2- - shows a variant of the assembly shown in Figure 1.
Les éléments correspondants de ce montage sont ceur de la figure 1 et portent de ce fait des repères correspondants augmentés de l'in- dice 200.The corresponding elements of this arrangement are the cores of FIG. 1 and therefore bear corresponding marks increased by the index 200.
Directement sur la queue creuse 207 de l'élément 206, est usinée une portée 216 de roulement qui reçoit une ou deux bagues intérieures217, 218 du roulement à déux rangées de corps roulants 10 à contact oblique.Directly on the hollow tail 207 of the element 206, a bearing surface 216 is machined which receives one or two inner rings 217, 218 of the two-row bearing of rolling bodies 10 with oblique contact.
La bague extérieure Il du roulement, qui porte les pistes de roulement des corps 10, possède une bride de fixation 12 au support 13.The outer ring II of the bearing, which carries the tracks of the bodies 10, has a fixing flange 12 to the support 13.
Les bagues intérieures 217, 218 sont par ailleurs disposées entre l'épaulement 204 de la bride 202 et une deuxième face d'appui et de butée 219 prévue sur 1 élément 206 du joint homocinétique.The inner rings 217, 218 are also arranged between the shoulder 204 of the flange 202 and a second bearing and abutment face 219 provided on 1 element 206 of the constant velocity joint.
Le processus de réalisation de ce montage est le suivant
On monte l'ensemble du roulement avec la bague intérieure 217, 218 sur la queue 207 de l'élément 206. On pousse ensuite l'ensemble précité en direction de la bride 202 pour qu'il vienne en contact avec l'épaulement 204. On serre axialement l'élément 206 du joint homocinétique et le moyeu 201 jusqu'à l'obtention de la pression de-contact suffisante entre la face d'appui 219 et la face latérale de la bague 218.The process for producing this assembly is as follows
The bearing assembly is mounted with the inner ring 217, 218 on the tail 207 of the element 206. The above-mentioned assembly is then pushed in the direction of the flange 202 so that it comes into contact with the shoulder 204. The element 206 of the constant velocity joint and the hub 201 are tightened axially until sufficient contact pressure is obtained between the bearing face 219 and the lateral face of the ring 218.
On opère ensuite la liaison par soudure entre la queue 207 et le moyeu 201au niveau de lasurface cylindrique d'assemblage et alésage 209 prévue à la périphérie interne de la queue 207. The connection is then made by welding between the tail 207 and the hub 201 at the level of the cylindrical surface for assembly and bore 209 provided at the internal periphery of the tail 207.
La variante de réalisation du montage de roue, représentée à la figure 3, qui n'a pas besoin d'entre décrite dans son ensemble, possède une configuration semblable à celle des figures 1, 2 et porte de ce fait les repères correspondants des organes et éléments du montage précédemment décrit à la figure 1 augmentés de l'indice 300. I1 y a toutefois lieu de remarquer que la surface de raccordement de la qu eue 307 au moyeu 301 est constituée par une denture ou cannelure 320 situées à la surface cylindrique externe de la queue 307. The variant embodiment of the wheel assembly, shown in FIG. 3, which does not need to be described as a whole, has a configuration similar to that of FIGS. 1, 2 and therefore bears the corresponding references of the members and elements of the assembly previously described in FIG. 1 increased by the index 300. It should however be noted that the connection surface of the rod 307 to the hub 301 consists of a toothing or groove 320 situated on the cylindrical surface tail external 307.
L'élément mené 306 du joint de transmission possède une configuration générale creuse qui peut porter le triaxe à galets d'un joint homocinétique tel que décrit dans le brevet français 2 298 035 et qui se prolonge par la queue 307 emboitée dans une denture intérieure 321 d'assemblage portée par le moyeu 301. The driven element 306 of the transmission joint has a generally hollow configuration which can carry the roller triaxis of a constant velocity joint as described in French patent 2,298,035 and which is extended by the tail 307 fitted into an internal toothing 321 assembly carried by the hub 301.
La bague extérieure fixe 311 du palier à roulement est comparable à celle représentée sur le montage de la figure 1 ou 2. The fixed outer ring 311 of the rolling bearing is comparable to that shown in the assembly of FIG. 1 or 2.
La bague intérieure réalisée sous forme de piste de roulement est intégrée au moyeu 301. Le moyeu 301 porte par ailleurs deux épaulements latéraux 322, 323 axialement séparés par la denture 320 et possède un nez orienté vers le diamètre extérieur de l'élément mené 306 du joint homocinétique. Une telle configuration du moyeu 301 limite l'encombrement axial et radial du montageoaux exemples précédents bien que le plan médian A du palier 308 soit axialement décalé par rapport au plan médian B de la queue 307.The inner ring produced in the form of a running track is integrated into the hub 301. The hub 301 also carries two lateral shoulders 322, 323 axially separated by the teeth 320 and has a nose oriented towards the outside diameter of the driven element 306 of the constant velocity joint. Such a configuration of the hub 301 limits the axial and radial size of the montageoaux previous examples although the median plane A of the bearing 308 is axially offset from the median plane B of the tail 307.
Le processus de réalisation de ce montage est le suivant - On monte l'ensemble palier de roulement intégré au moyeu 301 sépa
rément de la transmission.The process for producing this assembly is as follows - We mount the bearing assembly integrated into the hub 301 sep
transmission.
- On assemble la transmission complète incluant le joint homocinétique assemblé sur ltensemble constitué par le moyeu et le roulement. - The complete transmission is assembled including the constant velocity joint assembled on the assembly constituted by the hub and the bearing.
- On immobilise axialement les deux ensembles ainsi assemblés au moyen
d'une rondelle arrêtoir ou tout autre moyen connu 330 susceptible
d'exercer un effort de serrage axial suffisant sur l'épaulement 322
dans le but de limiter les déplacements axiaux parasites éventuels
du moyeu 301 par rapport au joint homocinétique.- The two assemblies thus assembled are axially immobilized by means
a locking washer or any other known means 330 capable of
to exert a sufficient axial clamping force on the shoulder 322
in order to limit possible parasitic axial displacements
of the hub 301 with respect to the constant velocity joint.
Selon l'exemple représenté à la figure 4 qui n'est qu'une variante du montage précédent, la bague intérieure du roulement 417 est emboitée sur le moyeu 401 et on exerce par un moyen de serrage conventionnel 430 un effort axial dans le but d'immobiliser axialement le palier 408 entre deux épaulements.d'appui 404 et 419 respectivement situés sur la bride 402 et sur l'élément mené 406 du joint homocinétique. According to the example shown in Figure 4 which is only a variant of the previous assembly, the inner ring of the bearing 417 is fitted on the hub 401 and is exerted by a conventional clamping means 430 an axial force for the purpose of axially immobilize the bearing 408 between two support shoulders 404 and 419 respectively located on the flange 402 and on the driven element 406 of the constant velocity joint.
Les exemples dtcrits en référence. des figures 3, 4 présententl'avan- tage d'autoriser la séparation aisée des éléments du montage dans le but de remplacer localement les pièces Jzfectueuses sans mise au rebut des pièces récupérables.The examples described with reference. of Figures 3, 4 show the advantage of allowing easy separation of the assembly elements with the aim of locally replacing the defective parts without discarding the recoverable parts.
L'ensemble des exemples décrits autorise l'emploi d'éléments menés de joints homocinétiques obtenus par un procédé de filage connu en soi en une ou plusieurs parties assemblées. All of the examples described allow the use of driven elements of constant velocity joints obtained by a spinning process known per se in one or more assembled parts.
