Description
La présente invention a pour objet un ensemble de croisillon pour joint de transmission, du type comprenant un croisillon qui comporte un moyeu destiné<B>à</B> être relié<B>à</B> un arbre et sur lequel font saillie plusieurs bras, lesquels comportent chacun une surface de roulement cylindrique et un chapeau d'extrémité, un galet monté rotatif et coulissant sur chaque bras par l'intermédiaire d'une couronne d'aiguilles, et un organe de retenue de chaque galet et de la couronne d'aiguilles sur le bras. The present invention relates to a set of spider for transmission joint, of the type comprising a spider which comprises a hub for <B> to </ B> be connected <B> to </ B> a shaft and on which protrude a plurality of arms, each having a cylindrical bearing surface and an end cap, a roller rotatably mounted to slide on each arm via a ring of needles, and a retainer of each roller and the crown of needles on the arm.
L'invention s'applique, par exemple, aux joints homocinétiques<B>à</B> tripode utilisés dans des transmissions de véhicules automobiles. The invention is applicable, for example, to homokinetic joints <B> to </ B> tripod used in motor vehicle transmissions.
Dans les joints de transmission comprenant un ensemble de croisillon de ce type, les galets sont, après assemblage du joint, emprisonnés dans des pistes de l'élément femelle de ce joint. Par suite, si le joint est livré assemblé, les galets ne peuvent s'échapper de "l'eurs bras. In the transmission joints comprising a spider assembly of this type, the rollers are, after assembling the seal, trapped in tracks of the female element of this joint. As a result, if the seal is delivered assembled, the rollers can not escape from their arms.
En revanche, dans certains cas, il est nécessaire de livrer séparément, d'une part le croisillon équipé de galets et d'aiguilles, et d'autre part l'élément femelle, l'assemblage s'effectuant sur une chaÎne de montage du véhicule. Il est alors nécessaire de prévoir des moyens de retenue de chaque galet sur son bras. However, in some cases, it is necessary to deliver separately, on the one hand the spider equipped with rollers and needles, and on the other hand the female element, the assembly being performed on a mounting chain of the vehicle. It is then necessary to provide means for retaining each roller on its arm.
Dans la technologie actuelle de retenue des galets (voir par exemple les joints de type GI commercialisés par la société GNK GLAENZER SPICER), on utilise une bague de retenue axiale qui intègre deux fonctions<B>:</B> la retenue des aiguilles-et la retenue du galet. In the current roller retention technology (see for example GI type gaskets marketed by the GNK GLAENZER SPICER company), an axial retaining ring is used which integrates two functions <B>: </ B> the retention of the needles. and the retention of the roller.
Dans la partie de retenue des aiguilles, la bague est circulaire et fermée, tandis que, dans la partie de retenue du galet, elle comporte un ou plusieurs becquets qui font saillie radialement vers l'extérieur. In the needle retaining portion, the ring is circular and closed, while in the retaining portion of the roller, it has one or more spoilers that protrude radially outwardly.
Cette bague est montée axialement mobile sur le bras. Elle est associée<B>à</B> un jonc ouvert qui s'encliquette dans une gorge située<B>à</B> l'extrémité du bras, jonc qui permet le montage et la retenue de cette bague. Une fois montée, la bague est retenue entre les aiguilles et le jonc ouvert. La bague de retenue est conformée en coupelle d'une façon telle que les becquets de retenue de galet sont axialement décalés vers l'extrémité libre du bras par rapport<B>à</B> la surface de retenue des aiguilles afin de permettre aux galets de coulisser axialement pendant le fonctionnement. This ring is mounted axially movable on the arm. It is associated <B> with </ B> an open snap which snaps into a groove located at the end of the arm, ring which allows the assembly and the retention of this ring. Once mounted, the ring is retained between the needles and the ring open. The retaining ring is cup-shaped in such a way that the roller retention spoilers are axially offset towards the free end of the arm relative to the needle retaining surface to allow rollers slide axially during operation.
<B>A</B> cause des limitations d'espace, la bague est formée d'une façon telle que sa partie intermédiaire cylindrique coiffe le jonc ouvert lorsque les aiguilles sont montées. En conséquence, le montage est effectué de la façon suivante<B>:</B> la bague de retenue est enfilée sur le bras; le jonc ouvert est encliqueté dans la gorge<B>;</B> la bague de retenue est coulissée vers le jonc ouvert, coiffant ainsi celui-ci en libérant la place aux aiguilles, qui sont montées ensuite. Enfin, il faut monter le galet par-dessus les becquets de retenue de la bague. Ces derniers doivent donc<B>à</B> la fois permettre le passage du galet pour le montage et en assurer la retenue après le montage. Les efforts de retenue sont donc limités par cette double contrainte, la retenue est dite<B> </B> semi-positive <B> .</B> <B> A </ B> causes space limitations, the ring is formed in such a way that its cylindrical intermediate portion caps the ring when the needles are mounted. Consequently, the assembly is carried out in the following manner: the retaining ring is threaded onto the arm; the open ring is snapped into the groove <B>; </ B> the retaining ring is slid towards the open ring, thus capping the latter by releasing the place to the needles, which are then mounted. Finally, it is necessary to mount the roller over the retaining spoilers of the ring. These must therefore <B> to </ B> both allow the passage of the roller for mounting and ensure retention after assembly. The restraint forces are therefore limited by this double constraint, the restraint is called <B> </ B> semi-positive <B>. </ B>
Les désavantages de cette construction sont premièrement des efforts de retenue du galet limités et deuxièmement un coÛt d'assemblage élevé. The disadvantages of this construction are first limited roller restraint efforts and secondly high assembly cost.
L'invention a pour but de fournir des moyens de retenue des aiguilles et de galet qui soient économiques et qui permettent une retenue positive du galet même sous les contraintes d'espace habituellement présentes dans les joints du type précité. The object of the invention is to provide means for retaining the needles and roller which are economical and which allow positive retention of the roller even under the space constraints usually present in the joints of the aforementioned type.

The invention will be better understood by reading the description which will follow, given only by way of example and with reference to the appended drawings in which <B> : </ B> <B> - </ B> Figure <B> 1 </ B> is a meridian sectional view of a set of compliant braces <B> to </ B> the invention <B> Figure 2 is a top view of the spider assembly of Figure 1; Figure <-> </ b> B> 3 </ B> is a larger scale view of a detail in Figure 1, in another position of the wheel.
on a représenté sur la Figure<B>1</B> un ensemble de croisillon de joint de transmission homocinétique du type tripode. Cet ensemble de croisillon comprend un croisillon<B>1</B> constitué d'un corps central ou moyeu 2 annulaire d'axe X-X supposé horizontal sur lesquels font saillie radialement trois bras<B>3</B> d'axe Y-Y disposés angulairement <B>à</B> 1200 les uns des autres<B>;</B> et, sur chaque bras<B>3,</B> une couronne d'aiguilles 4, un galet<B>5</B> ayant une surface extérieure sphérique<B>6</B> et un alésage cylindrique<B>7,</B> et une bague<B>8</B> de retenue. FIG. 1 shows a homokinetic transmission joint assembly of the tripod type. This set of spider comprises a spider <B> 1 </ B> consisting of a central body or hub 2 annular XX axis assumed horizontal on which radially project three arms <B> 3 </ B> axis YY arranged angularly <B> to </ B> 1200 from each other <B>; </ B> and, on each arm <B> 3, </ B> a crown of needles 4, a roller <B> 5 </ B> having a spherical outer surface <B> 6 </ B> and a cylindrical bore <B> 7, </ B> and a retaining ring <B> 8 </ B>.
La bague<B>8</B> de retenue assure<B>à</B> elle seule une retenue axiale positive des aiguilles 4 et également une retenue positive du galet<B>5.</B> The retaining ring <B> 8 </ B> ensures <B> to </ B> it only a positive axial retention of the needles 4 and also a positive retention of the roller <B> 5. </ B>
Les expressions<B> </B> bas<B> , </B> haut<B> , </B> inférieur<B> </B> et <B> </B> supérieur<B> </B> font, dans la description qui suit, référence <B>à</B> l'axe X-X et<B>à</B> l'orientation des Figures<B>1</B> et<B>3,</B> de façon qu' inférieur<B> </B> désigne une position rapprochée de cet axe. <B> </ B> Bottom <B>, <B>, <B> </ B> Bottom, and <B> </ B> Bottom <B> </ B > in the following description, reference <B> to </ B> the axis XX and <B> to </ B> the orientation of Figures <B> 1 </ B> and <B> 3, </ B> so that <B> </ B> denotes a close position of this axis.
De même, les dénominations<B> </B> intérieur<B> </B> et <B> </B> extérieur<B> </B> sont utilisées par rapport<B>à</B> l'axe Y-Y de façon qu' <B> </B> intérieur<B> </B> désigne une position rapprochée de cet axe Y-Y. Similarly, the names <B> </ B> inside <B> </ B> and <B> <B> <B> <B> <B> </ B> are used in relation <B> to </ B> the YY axis so that <B> </ B> inside <B> </ B> designates a position close to this axis YY.
L'alésage central<B>9</B> du corps 2 est calé pour son montage sur un arbre de transmission non représenté. Chaque bras<B>3</B> comporte pr-'_#s de son extrémité libre une gorge de retenue<B>10</B> circu!3.;re d'axe Y-Y qui sépare la partie principale courante du bras<B>3</B> d'un chapeau d'extrémité<B>il.</B> Ce chapeau<B>11</B> est constitué successivement d'une partie inférieure cylindrique<B>11A,</B> d'une partie conique convergente 11B et une partie supérieure<B>11C</B> en forme de calotte sphérique. La partie courante du bras comporte une surface de roulement cylindrique 12 d'axe Y-Y qui se termine vers l'axe X-X au voisinage d'un épaulement 14 du corps 2.<B>A</B> son extrémité supérieure, la surface 12 est délimitée par la gorge circulaire<B>10.</B> The central bore <B> 9 </ B> of the body 2 is keyed for its mounting on a not shown drive shaft. Each arm <B> 3 </ B> has at its free end a retaining groove <B> 10 </ B> circu 3. Ye axis which separates the main part of the current arm <B> 3 </ B> of an end cap <B> il. </ B> This cap <B> 11 </ B> consists successively of a cylindrical lower part <B> 11A, < / B> of a convergent conical portion 11B and an upper portion <B> 11C </ B> shaped spherical cap. The current part of the arm comprises a cylindrical rolling surface 12 of axis YY which ends towards the axis XX in the vicinity of a shoulder 14 of the body 2. <B> A </ B> its upper end, the surface 12 is bounded by the circular gorge <B> 10. </ B>
Les aiguilles 4 sont reçues dans l'espace formé par la surface de roulement 12, l'épaulement 14 et la bague<B>8.</B> Elles roulent<B>à</B> la fois sur la surface de roulement 12 et dans l'alésage<B>7</B> du galet. Par conséquent, en absence de la bague<B>8,</B> le galet et les aiguilles pourraient s'échapper par coulissement vers l'extérieur des bras<B>3</B> qui les portent. The needles 4 are received in the space formed by the running surface 12, the shoulder 14 and the ring <B> 8. </ B> They roll <B> to </ B> both on the running surface 12 and in the bore <B> 7 </ B> of the roller. Therefore, in the absence of the ring <B> 8, </ B> the roller and needles could escape by sliding out of the arms <B> 3 </ B> that carry them.
Pour éviter ceci, et donc permettre une manutention sure du croisillon équipé des aiguilles et des galets, la bague<B>8</B> assure une retenue positive du galet et des aiguilles sur leur bras avant le montage de l'ensemble de croisillon dans l'élément femelle du joint, de la manière suivante. To avoid this, and thus allow safe handling of the spider equipped with needles and rollers, the ring <B> 8 </ B> ensures a positive retention of the roller and needles on their arm before mounting the set of spider in the female element of the seal, as follows.
Sur la Figure 2, on voit le bras<B>3</B> de la Figure<B>1</B> de dessus, avec le galet<B>5,</B> le chapeau<B>il</B> et la bague<B>8.</B> La bague<B>8</B> possède une fente verticale<B>15</B> inclinée<B>à</B> 450 su'r la direction radiale, qui traverse la totalité de la section transversale de la bague. In Figure 2, we see the arm <B> 3 </ B> of the Figure <B> 1 </ B> from above, with the roller <B> 5, </ B> the hat <B> it < / B> and the ring <B> 8. </ B> The ring <B> 8 </ B> has a vertical slot <B> 15 </ B> inclined <B> to </ B> 450 su'r the radial direction, which crosses the entire cross section of the ring.
Cette bague<B>8</B> est réalisée de préférence en acier<B>à</B> ressort. La bague<B>8</B> comporte un tronçon principal 20 intérieurement et extérieurement cylindrique. Lorsque la bague est au repos, ce tronçon 20 a un diamètre extérieur inférieur au diamètre de l'alésage<B>7</B> du galet et un diamètre intérieur légèrement inférieur au diamètre de la surface <B>11A</B> du bras. This ring <B> 8 </ B> is preferably made of steel <B> to </ B> spring. The ring <B> 8 </ B> has a main section 20 internally and externally cylindrical. When the ring is at rest, this section 20 has an outside diameter smaller than the diameter of the bore <B> 7 </ B> of the roller and an inside diameter slightly smaller than the diameter of the surface <B> 11A </ B> of the arm.
La bague<B>8</B> comporte en outre intérieurement,<B>à</B> son extrémité inférieure, un bourrelet 21 périphérique encliqueté dans la gorge<B>10</B> de retenue du bras, assurant ainsi la retenue axiale de la bague<B>8</B> sur le bras. The ring <B> 8 </ B> furthermore has, internally, <B> at </ B> its lower end, a peripheral bead 21 snapped into the retaining groove of the arm, thus ensuring the axial retention of the ring <B> 8 </ B> on the arm.
La surface intérieure 22 de la bague<B>8</B> enserre élastiquement la surface cylindrique<B>11A</B> du chapeau<B>11</B> et s'étend vers le haut presque jusqu'à l'extrémité du bras<B>3.</B> La tranche d'extrémité supérieure<B>23</B> de la bague est tronconique et convergente vers le haut. La tranche d'extrémité inférieure de la bague<B>8</B> forme une surface 24 de retenue des aiguilles. Elle est tronconique et s'évase vers le haut. En section méridienne (Figure<B>3),</B> la paroi 24 fait avec l'axe X-X un angle # faible, de<B>70</B> par exemple. <B>A</B> son autre extrémité, la bague<B>8</B> comporte extérieurement sur sa périphérie un rebord 26 de retenue du galet. Ce rebord<B>26</B> est décalé axialement par rapport au bourrelet 21, vers la partie supérieure du bras<B>3.</B> Le rebord <B>26</B> présente en regard du galet<B>5</B> une surface inférieure chanfreinée<B>28,</B> convergente vers le bas. Cette surface 28 est adaptée pour coopérer avec un chanfrein conjugué<B>30</B> ménagé<B>à</B> l'extrémité supérieure de l'alésage cylindrique<B>7</B> du galet, lorsque ce galet est dans une position supérieure extrême sur le bras<B>3.</B> Dans cette position, représentée sur la Figure<B>3,</B> l'alésage cylindrique<B>7</B> recouvre le tronçon principal 20 de la bague et le rebord<B>26</B> est reçu essentiellement dans l'espace délimité par le chanfrein<B>30</B> du galet. Ainsi le rebord<B>26</B> ne constitue pas un obstacle au déplacement libre du tripode dans l'élément femelle du joint, et n'interfère pas avec les parois internes de l'élément femelle du joint. Les surfaces sphérique fiC et tronconique 24 contribuent également<B>à</B> la réduction de l'encombrement du joint. The inner surface 22 of the ring <B> 8 </ B> elastically encloses the cylindrical surface <B> 11A </ B> of the cap <B> 11 </ B> and extends upwards almost to the top. The end of the arm <B> 3. </ B> The upper end edge <B> 23 </ B> of the ring is frustoconical and convergent upwards. The lower end edge of the ring <B> 8 </ B> forms a surface 24 for retaining the needles. It is frustoconical and flares upward. In meridian section (Figure <B> 3), </ B> the wall 24 makes with the axis X-X a low angle #, <B> 70 </ B> for example. <B> A </ B> at its other end, the ring <B> 8 </ B> has externally on its periphery a rim 26 for retaining the roller. This flange <B> 26 </ B> is offset axially relative to the bead 21, towards the upper part of the arm <B> 3. </ B> The flange <B> 26 </ B> presents next to the roller < B> 5 </ B> bottom bevelled bottom <B> 28, </ B> converging downward. This surface 28 is adapted to cooperate with a conjugated chamfer <B> 30 </ B> arranged <B> at </ B> the upper end of the cylindrical bore <B> 7 </ B> of the roller, when this roller is in an extreme upper position on the arm <B> 3. </ B> In this position, shown in Figure <B> 3, </ B> the cylindrical bore <B> 7 </ B> covers the main section 20 of the ring and the rim <B> 26 </ B> is received essentially in the space defined by the chamfer <B> 30 </ B> of the roller. Thus the flange <B> 26 </ B> does not constitute an obstacle to the free movement of the tripod in the female element of the seal, and does not interfere with the internal walls of the female element of the seal. The spherical and frustoconical surfaces 24 also contribute to reducing the bulkiness of the joint.
Afin d'assurer le montage d'un tel agencement, on monte tout d'abord la couronne d'aiguilles 4 et le galet<B>5,</B> puis enfin la bague<B>8,</B> qui est mise en place en se déformant élastiquement. La partie conique 11B du chapeau du bras<B>3</B> facilite le montage de la bague<B>8,</B> permettant une ouverture de la bague lorsqu'elle est poussée axialement vers le bas. on comprend que la bague<B>8</B> assure alors par l'intermédiaire du rebord<B>26</B> une retenue positive du galet<B>5.</B> In order to ensure the mounting of such an arrangement, the ring of needles 4 and the roller <B> 5, </ B> and finally the ring <B> 8, </ B> are first mounted. is put in place by deforming elastically. The conical portion 11B of the cap of the arm <B> 3 </ B> facilitates the mounting of the ring <B> 8, </ B> allowing an opening of the ring when it is pushed axially downwards. it is understood that the ring <B> 8 </ B> ensures then by means of the flange <B> 26 </ B> a positive retention of the roller <B> 5. </ B>
L'alésage<B>7</B> du galet<B>5</B> est légèrement plus grand que le diamètre extérieur du tronçon principal 20<B>à</B> l'état monté mais est choisi assez petit pour que le bourrelet 21 ne puisse pas s'échapper de la gorge de retenue<B>10</B> pendant que le galet exerce un effort sur la bague<B>8,</B> soit pendant la manipulation lors du montage du joint, soit pendant l'utilisation du joint sous angle. En outre, le diamètre de la surface<B>11A</B> est légèrement plus grand que le diamètre de la surface intérieure 22 lorsque la bague est au repos. Ceci a pour effet que la fente<B>15</B> ne se referme pas complètement lorsque la bague<B>8</B> est montée sur le bras<B>3.</B> Néanmoins, les diamètres doivent être choisis d'une telle façon que la fente<B>15</B> reste suffisamment petite pour que les aiguilles 4 ne s'y engagent pas pendant le fonctionnement. The bore <B> 7 </ B> of the roller <B> 5 </ B> is slightly larger than the outer diameter of the main section 20 <B> to </ B> the mounted state but is chosen rather small so that the bead 21 can not escape from the retaining groove <B> 10 </ B> while the roller exerts a force on the ring <B> 8, </ B> either during handling during assembly seal, or during the use of the angle joint. In addition, the diameter of the surface <B> 11A </ B> is slightly larger than the diameter of the inner surface 22 when the ring is at rest. This causes the <B> 15 </ B> slot to not close completely when the <B> 8 </ B> ring is mounted on the <B> 3 arm. </ B> However, the diameters must be chosen in such a way that the slot <B> 15 </ B> remains small enough that the needles 4 do not engage during operation.
En variante, le diamètre de la surface<B>11A</B> peut être légèrement plus petit que le diamètre de la surface intérieure 22 lorsque la bague<B>8</B> est au repos et, en conséquence la bague est montée libre sur le bras et la fente<B>15</B> se referme lors du montage. Dans cette variante, les dimensions du bourrelet 21 doivent être choisies d'une façon telle que la bague ne s'échappe pas de la gorge<B>10</B> pendant le fonctionnement. Alternatively, the diameter of the surface <B> 11A </ B> may be slightly smaller than the diameter of the inner surface 22 when the ring <B> 8 </ B> is at rest and, accordingly, the ring is free rise on the arm and the slot <B> 15 </ B> closes during assembly. In this variant, the dimensions of the bead 21 must be chosen in such a way that the ring does not escape from the groove <B> 10 </ B> during operation.
Il est<B>à</B> noter que grâce<B>à</B> la forme conique des surfaces 24 et<B>28</B> de la bague, les efforts axiaux exercés par les aiguilles et par le galet sur cette bague tendent<B>à</B> refermer celle-ci, et donc<B>à</B> améliorer la retenue de la bague sur le bras et<B>à</B> réduire la largeur de la fente<B>15</B> en fonctionnement. It is <B> to </ B> note that thanks to <B> to </ B> the conical shape of the surfaces 24 and <B> 28 </ B> of the ring, the axial forces exerted by the needles and by the roller on this ring tend to close it, and therefore to improve the retention of the ring on the arm and to reduce the width of the ring. the slot <B> 15 </ B> in operation.
De plus, l'utilisation d'une bague de retenue'c'omme proposé par l'invention permet de supprimer le jonc ouvert utilisé jusqu'à présent et ainsi de renforcer la bague<B>8</B> de retenue par la matière équivalente<B>à</B> ce Jonc. In addition, the use of a retaining ring'c 'as proposed by the invention allows to remove the open ring used until now and thus strengthen the ring <B> 8 </ B> retaining by the equivalent material <B> to </ B> this rush.
En variante, le bourrelet 21 et/ou le rebord<B>26</B> peuvent être discontinus, afin d'augmenter l'élasticité de la bague<B>8</B> pour faciliter sa mise en place.Alternatively, the bead 21 and / or the rim <B> 26 </ B> may be discontinuous, to increase the elasticity of the ring <B> 8 </ B> to facilitate its implementation.
