Abstract

The transmission comprises a shaft with three, equi-spaced radial arms terminating in a spherical end (3). A carrier (12) with spherical bearing surface (4), rotates about the arm (3). This assembly slides with a tube (10) with three pairs of equi-spaced longitudinal tracks (11). Ball bearings (15) contained in a cage (16) are interposed between the tracks (11) and carriers (12). The bearing surfaces (14a,14b) of the carriers are tapered such that the distance between these surfaces and the tracks (11) increase from the central stops (17). ADVANTAGE - Ball bearings and carriers (12) are maintained in mean relative positions and rolling contact is thus maintained.

Description

La présente invention concerne les joints homocinétiques coulissants pouvant être utilisés, notamment, dans des transmissions latérales de véhicule automobile. The present invention relates to sliding homokinetic joints that can be used, in particular, in lateral transmissions of a motor vehicle.

On a décrit au brevet principal FR-A-85 05 995 un joint homocinétique coulissant comprenant un premier organe orienté suivant un premier axe et portant trois bras radiaux qui sont régulièrement espacés angulairement et délimitent des portées sphériques, un deuxième organe ayant un deuxième axe sécant avec le premier et pouvant former un angle avec lui, ce deuxième organe délimitant trois paires de chemins de roulement constitués par des surfaces cylindriques de section sensiblement circulaire et de génératrices parallèles à l'axe du deuxième organe, des éléments intermédiaires disposés entre lesdites portées sphériques et lesdits chemins de roulement, ces éléments intermédiaires délimitant d'une part une portée sphérique coopérant avec la portée sphérique associée du premier organe et d'autre part une piste pour des billes qui sont retenues par une cage.et constituent des éléments de roulement interposés entre les éléments intermédiaires et les chemins de roulement du deuxième organe. Patent FR-A-85 05 995 discloses a sliding constant velocity joint comprising a first member oriented along a first axis and carrying three radial arms which are regularly spaced angularly and delimit spherical bearings, a second member having a second axis intersecting with the first and being able to form an angle with it, this second member delimiting three pairs of raceways constituted by cylindrical surfaces of substantially circular section and generatrices parallel to the axis of the second member, intermediate elements disposed between said spherical bearing surfaces and said raceways, these intermediate elements delimiting on the one hand a spherical bearing cooperating with the associated spherical bearing surface of the first member and on the other hand a track for balls which are retained by a cage.and constitute rolling elements interposed between the intermediate elements and the runways of the second member.

Un tel joint possède des propriétés de libre coulissement et d'absence de réactions axiales qui en constituent les avantages principaux. Les éléments constitutifs du joint et notamment les éléments inter médiaires sont proportionnés de telle façon que pour les débattements normaux des organes du véhicule qu'ils relient, le joint fonctionne avec un mouvement en libre roulement des billes.Cependant, lors de situations exceptionnelles telles que franchissement d'une bordure de trottoir, passage du véhicule dans un "nid de poule", il arrive que le débattement axial du joint soit suffisamment important pour que les billes ne fonctionnent plus en libre roulement mais au contraire en glissement, ce qui se traduit par une résistance au coulissement relativement élevée. I1 en résulte
- l'apparition aléatoire de bruits liés au changement de mode de fonctionnement du joint,
- une augmentation des pressions de contact entre les billes et les chemins de roulement et donc une diminution de la durée de vie.
Such a seal has properties of free sliding and absence of axial reactions which are the main advantages. The constituent elements of the seal and in particular the intermediate elements are proportioned in such a way that for the normal deflections of the bodies of the vehicle they connect, the seal operates with a free rolling movement of the balls. However, in exceptional situations such as crossing a sidewalk, passing the vehicle in a "pothole", it happens that the axial movement of the seal is large enough that the balls do not work in free rolling but on the contrary sliding, which translates by a relatively high sliding resistance. I1 results
the random appearance of noises related to the change of operating mode of the joint,
an increase in contact pressures between the balls and the raceways and therefore a decrease in the service life.

L'invention a précisément pour objectif de résoudre ce problème et de perfectionner un joint tel que défini ci-dessus pour lui procurer un libre coulissement optimal quelles que soient ses conditions d'utilisation. The invention specifically aims to solve this problem and improve a seal as defined above to provide it free sliding optimal whatever its conditions of use.

A cet effet, un joint homocinétique coulissant tel que défini précédemment est caractérisé en ce que la piste ménagée sur chaque élément intermédiaire comporte deux portions dont la distance au chemin de roulement associé va en augmentant depuis une partie centrale de l'élément intermédiaire vers chacune de ses extrémités. For this purpose, a sliding homokinetic joint as defined above is characterized in that the track formed on each intermediate element comprises two portions whose distance to the associated raceway increases from a central part of the intermediate element to each of its ends.

L'invention va être décrite plus en détails ci-dessous en se référant aux dessins annexés donnés uniquement à titre d'exemple et sur lesquels
Les Fig. 1 A, I B, 1 C, 1 D illustrent schématiquement le fonctionnement d'un joint coulissant suivant le brevet principal;
La Fig. 2 est une vue en coupe d'un tel joint;
Les Fig. 3 et 4 sont des vues partielles à plus grande échelle illustrant un agencement selon l'invention.
The invention will be described in more detail below with reference to the accompanying drawings given by way of example and in which
Figs. 1A, 1B, 1C, 1D schematically illustrate the operation of a sliding joint according to the main patent;
Fig. 2 is a sectional view of such a seal;
Figs. 3 and 4 are partial views on a larger scale illustrating an arrangement according to the invention.

On a représenté de façon quelque peu schématique sur les figures 1 A à 1 D et sur la Fig. 2 un joint homocinétique coulissant tel que décrit dans le brevet FR-A-85 05 995, comprenant un premier organe constitué par un arbre 1 d'axe X-X, portant un tripode 2 comportant lui-meme trois bras ou tourillons radiaux 3, régulièrement espacés angulairement et qui délimitent des surfaces latérales sphériques convexes 4. Shown somewhat schematically in FIGS. 1A to 1D and in FIG. 2 a sliding constant velocity joint as described in patent FR-A-85 05 995, comprising a first member constituted by a shaft 1 of axis XX, carrying a tripod 2 itself comprising three arms or radial journals 3, regularly spaced angularly and delimiting convex spherical lateral surfaces 4.

Le joint comporte un deuxième organe constitué par un barillet 10 d'axe Y-Y, délimitant six chemins de roulement 11. Ces chemins de roulement ont une forme cylindrique, de section sensiblement circulaire et de génératrices parallèles à l'axe Y-Y. The seal comprises a second member constituted by a barrel 10 of axis Y-Y, delimiting six raceways 11. These raceways have a cylindrical shape, of substantially circular section and generatrices parallel to the Y-axis.

Chaque bras ou tourillon 3 à portées sphériques se trouve ainsi disposé entre deux chemins de roulement il du barillet et entre chaque portée sphérique et le chemin de roulement associé 11 est disposé un élément intermédiaire 12 délimitant sur un côté une portée sphérique concave 13 coopérant avec les surfaces de portée sphériques convexes des bras ou tourillons, et de l'autre côté des pistes 14 disposées en vis-à-vis des chemins de roulement du barillet. Each arm or pin 3 with spherical bearings is thus disposed between two raceways il of the cylinder and between each spherical bearing and the associated raceway 11 is disposed an intermediate element 12 delimiting on one side a concave spherical bearing surface 13 cooperating with the convex spherical bearing surfaces of the arms or journals, and the other side of the tracks 14 arranged vis-à-vis the raceways of the barrel.

Enfin, des billes 15 sont interposées entre lesdites pistes 14 et lesdits chemins de roulement 11, ces billes pouvant être, comme connu en soi, maintenues par des cages 16. Finally, balls 15 are interposed between said tracks 14 and said raceways 11, these balls being, as known per se, held by cages 16.

Suivant un mode de réalisation particulièrement avantageux, les éléments intermédiaires sont constitués par des barrettes et chaque piste coopérant avec les billes est divisée en deux portions ou deux segments 14a, 14b séparés par une paroi centrale 17. According to a particularly advantageous embodiment, the intermediate elements are constituted by bars and each track cooperating with the balls is divided into two portions or two segments 14a, 14b separated by a central wall 17.

Une telle réalisation permet de limiter le nombre de billes à une pour chaque segment de piste, comme représenté sur les Fig. 1 A à 1 D. Such an embodiment makes it possible to limit the number of balls to one for each segment of the track, as represented in FIGS. 1 to 1 D.

Ces figures illustrent le fonctionnement d'un tel joint, lors d'un débattement axial de plus en plus important, à partir d'une position extrême repré sensée à la Fig. 1 A. These figures illustrate the operation of such a seal, during an increasingly greater axial deflection, from an extreme position as shown in FIG. 1 A.

Sur la Fig. 1 B, le joint occupe une position axiale moyenne, les billes étant symétriques par rapport à un plan P passant par les axes des bras radiaux 3. In FIG. 1 B, the joint occupies an average axial position, the balls being symmetrical with respect to a plane P passing through the axes of the radial arms 3.

Le passage de la position de la Fig. 1 A à la position de la Fig. 1 B s'effectue par un roulement pur des billes et donc dans les meilleures conditions de libre coulissement axial. The passage of the position of FIG. 1A at the position of FIG. 1 B is carried out by a pure bearing of the balls and therefore in the best conditions of free axial sliding.

Il en est de même pour le passage de la position de la Fig. 1 B à la position de la Fig. 1 C, de sorte que pour la course C 1 représentée sur cette
Fig. 1 C, le joint fonctionne dans des conditions optimales de coulissement.
It is the same for the passage of the position of FIG. 1 B at the position of FIG. 1 C, so that for the stroke C 1 shown on this
Fig. 1 C, the seal operates under optimal conditions of sliding.

Par contre, pour atteindre la position de la
Fig. 1 D, les billes doivent travailler en glissement, et donc avec des efforts de coulissement relativement élevés. il en résulte notamment comme inconvénient une apparition aléatoire de bruits liés au changement de mode de fonctionnement du joint, et ce même durant des utilisations normales de ce joint, ainsi qu'une augmentation des charges sur les éléments de roulement, par suite de la dissymétrie dans la position des billes, ce qui a pour conséquence une augmentation des pressions de contact et donc une diminution de la durée de vie.
On the other hand, to reach the position of
Fig. 1 D, the balls must work in sliding, and therefore with relatively high sliding forces. this results in particular as a disadvantage a random appearance of noises related to the change of operating mode of the seal, and this even during normal uses of this seal, as well as an increase of the loads on the rolling elements, as a result of the dissymmetry in the position of the balls, which results in an increase in contact pressures and therefore a decrease in the service life.

Suivant l'invention et comme représenté aux
Fig. 3 et 4, lus pistes 14 prévues sur les éléments intermédiaires, tout en étant cylindriques, ont des génératrices qui au lieu d'être parallèles aux génératrices des chemins de roulement Il du barillet, sont orientées de telle façon que la distance entre les deux segments de piste ménagés sur chaque élément in- termédiaire et le chemin de roulement qui leur fait face va en augmentant depuis la partie centrale de cet élément vers ses extrémités.
According to the invention and as shown in
Fig. 3 and 4, the lanes 14 provided on the intermediate elements, while being cylindrical, have generatrices which instead of being parallel to the generatrices of the raceways 11 of the barrel, are oriented in such a way that the distance between the two segments Each of the intermediate tracks on each intermediate element and the raceway facing them is increasing from the central part of this element towards its ends.

En d'autres termes, si l'on désigne par Z-Z l'axe du chemin de roulement 11 et par V-V et W-W les deux axes des deux segments de piste prévus sur un élément intermédiaire, dans la position représentée à la Fig. 2, qui correspond à une position moyenne, les deux axes V-V et W-W forment un anglei avec l'axe Z-Z. In other words, if Z-Z denotes the axis of the raceway 11 and V-V and W-W the two axes of the two segments of track provided on an intermediate element, in the position shown in FIG. 2, which corresponds to an average position, the two axes V-V and W-W form an angle with the axis Z-Z.

La valeur de cet angle peut etre faible, par exemple inférieure à 1-. The value of this angle may be small, for example less than 1.

Dès que le joint est appelé à transmettre un couple, un effort Q est appliqué au centre de la portée sphérique de l'élément intermédiaire, en contact avec la portée correspondante du tripode. Cet effort est transmis aux billes et se décompose en deux ef- forts P1 et P2 dont la direction est normale aux axes des pistes de l'élément intermédiaire. As soon as the seal is called to transmit a torque, a force Q is applied to the center of the spherical bearing of the intermediate element, in contact with the corresponding range of the tripod. This force is transmitted to the balls and is broken down into two forces P1 and P2 whose direction is normal to the axes of the tracks of the intermediate element.

Sur la Fig. 3, les efforts P1 et P2 sont égaux. Ils sont appliqués aux billes qui sont en équilibre sous l'effet
- des réactions T1 et T2 au contact des billes et des pistes, qui sont toutes deux normales à l'axe des pistes 11 du barillet;
- des composantes F1 et F2 au contact entre les billes et les cages. Ces composantes s'opposent à la tendance naturelle qu'auraient les billes à s'écarter. Dans le cas d'une disposition symétrique, comme représenté sur la Fig. 2, ces composantes F1 et F2 sont égales en valeur et opposées en direction. Leur résultante est nulle et la cage 16 est simplement soumise à une tension.
In FIG. 3, the efforts P1 and P2 are equal. They are applied to the balls that are in balance under the effect
- T1 and T2 reactions in contact with the balls and tracks, which are both normal to the axis of the tracks 11 of the barrel;
- F1 and F2 components in contact between the balls and the cages. These components are opposed to the natural tendency of the logs to deviate. In the case of a symmetrical arrangement, as shown in FIG. 2, these components F1 and F2 are equal in value and opposite in direction. Their resultant is zero and the cage 16 is simply subjected to a tension.

Si, comme représenté sur la Fig. 3, les billes sont excentrées, on constate ce qui suit
- les charges transmises aux billes ne sont plus égales. Dans le cas de la figure 4, par exemple, la charge P2 a augmenté alors que la charge P1 a diminué;
- l'inclinaison du segment de piste 14b par rapport au . chemin de roulement 11 du barillet a augmenté d'une quantité d < correspondant à l'inclinaison générale de l'élément intermédiaire, alors que l'inclinaison du segment de piste 14a a diminué d'autant;
- il en résulte que la composante F2 est beaucoup plus grande que la composante F1. La cage est donc soumise à un effort F2 - F1 qui tend à ramener les billes vers la position centrale d'équilibre.
If, as shown in FIG. 3, the balls are eccentric, we see the following
the charges transmitted to the balls are no longer equal. In the case of FIG. 4, for example, the charge P2 has increased while the charge P1 has decreased;
the inclination of the segment of track 14b with respect to. raceway 11 of the barrel has increased by an amount d <corresponding to the general inclination of the intermediate element, while the inclination of the segment of track 14a has decreased accordingly;
it follows that the component F2 is much larger than the component F1. The cage is therefore subjected to a force F2 - F1 which tends to return the balls to the central equilibrium position.

Si l'on néglige les efforts de résistance en roulement des billes qui sont très faibles par rapport aux efforts transmis, la valeur de l'effort de recentrage est donnée par la formule suivante
F2 - F1 = 2 Q.g , x/a où
- Q représente l'effort exercé sur l'élément intermédiaire, sous couple;
-o( est l'angle d'inclinaison des pistes exprimé en radians;
I représente la moitié de la distance entre les centres des deux billes;
x représente l'écart entre la position de l'élément intermédiaire et sa position de symétrie par rapport aux billes.
If the bearing resistance forces of the balls, which are very small compared to the forces transmitted, are neglected, the value of the refocusing force is given by the following formula
F2 - F1 = 2 Qg, x / a where
Q represents the force exerted on the intermediate element, under torque;
-o (is the angle of inclination of the tracks expressed in radians;
I represents half the distance between the centers of the two balls;
x represents the difference between the position of the intermediate element and its position of symmetry with respect to the balls.

La valeur de l'effort de rappel ou de recentrage est donc proportionnelle au couple transmis, à l'angle d'inclinaison des pistes, et à l'écart par rapport à une position symétrique d'équilibre. The value of the return or refocusing force is therefore proportional to the torque transmitted, to the angle of inclination of the tracks, and to the deviation from a symmetrical equilibrium position.

A titre d'exemple, pour un joint transmettant un couple de 300 mN, les efforts Q sont de l'or- dre de 4000 N. By way of example, for a seal transmitting a torque of 300 mN, the forces Q are of the order of 4000 N.

Pour un rapport x/a de 0,5, un angle d'inclinaison très faible de l'ordre de 0,5 degré permet d'obtenir un effort de recentrage de l'ordre de 35 N. For a ratio x / a of 0.5, a very low angle of inclination of the order of 0.5 degrees makes it possible to obtain a recentering effort of the order of 35 N.

On voit donc que l'agencement proposé permet de remédier de façon efficace au problème posé en assurant un rappel automatique des éléments de roulement vers une position moyenne symétrique dans laquelle ils peuvent fonctionner de façon optimale, éliminant ainsi un fonctionnement avec glissement, même dans des conditions d'utilisation extrêmes du joint.  It can therefore be seen that the proposed arrangement makes it possible to effectively remedy the problem posed by ensuring an automatic return of the rolling elements to a symmetrical average position in which they can operate optimally, thus eliminating sliding operation, even in extreme conditions of use of the joint.
