Abstract
Description
La présente invention concerne un différentiel, notamment pour une transmission de véhicule automobile. The present invention relates to a differential, in particular for a motor vehicle transmission.
L'invention concerne plus particulièrement un différentiel du type comportant au moins une paire de pignons satellites opposés montés libres en rotation sur un axe dont les extrémités sont reçues dans des orifices ménagés dans deux portions opposées de la paroi du boîtier du différentiel. The invention relates more particularly to a differential of the type comprising at least one pair of opposite planet gears mounted free in rotation on an axis whose ends are received in orifices formed in two opposite portions of the wall of the differential housing.
Dans un différentiel de ce type, également appelé différentiel sphérique, le couple est transmis aux satellites par l'intermédiaire de leur axe de rotation. In a differential of this type, also called a spherical differential, the torque is transmitted to the satellites via their axis of rotation.
Afin d'améliorer les conditions de fonctionnement du différentiel, et d'éviter notamment des phénomènes de grippage des satellites, il s'est avéré souhaitable que les extrémités de l'axe soient libres en rotation dans les orifices de la paroi du boîtier qui les reçoivent. In order to improve the operating conditions of the differential, and in particular to avoid phenomena of seizure of the satellites, it has proved desirable that the ends of the axis are free to rotate in the orifices of the wall of the housing which receive.
Il s'est donc avéré nécessaire d'assurer une retenue axiale de l'axe par rapport au boîtier du différentiel. It therefore proved necessary to ensure an axial retention of the axis relative to the differential housing.
Afin de réduire l'encombrement radial du différentiel, il a déjà été proposé dans le document FR-A2.490.764 que les moyens de retenue axiale de l'axe soient agencés à l'intérieur du différentiel et coopèrent avec une portion médiane de l'axe située entre les deux pignons satellites. In order to reduce the radial size of the differential, it has already been proposed in document FR-A2.490.764 that the axial retaining means of the axis are arranged inside the differential and cooperate with a middle portion of the axis located between the two planet gears.
Dans cette solution, l'axe est maintenu en position à l'aide d'un téton circulaire formé à l'extrémité de l'ensemble du planétaire de sortie du différentiel et qui est reçu dans une gorge formée dans la portion médiane de l'axe des pignons satellites. Cette solution est complexe et difficile à mettre au point car il est nécessaire d'assurer un positionnement axial précis et constant de l'extrémité du planétaire conique sur laquelle est formé le téton de retenue afin de s'assurer que ce dernier est bien constamment en position dans la gorge de l'axe de rotation des satellites. In this solution, the axis is held in position by means of a circular stud formed at the end of the assembly of the planetary output from the differential and which is received in a groove formed in the middle portion of the axis of the planet gears. This solution is complex and difficult to develop since it is necessary to ensure precise and constant axial positioning of the end of the conical sun gear on which the retaining stud is formed in order to ensure that the latter is indeed constantly in position in the groove of the axis of rotation of the satellites.
De plus, la surface de contact entre le téton et les flancs de la gorge est très faible et la fiabilité de la retenue axiale n'est pas assurée en cas d'usure des surfaces en contact, et notamment du téton, qui est solidaire en rotation du planétaire. In addition, the contact surface between the stud and the sides of the groove is very small and the reliability of the axial retention is not ensured in the event of wear of the contact surfaces, and in particular of the stud, which is integral in planetary rotation.
Afin de remédier à ces inconvénients, l'invention propose un différentiel du type mentionné précédemment, caractérisé en ce que les moyens de retenue axiale de l'axe des pignons satellites comportent un organe de retenue lié en translation axiale à la portion médiane de l'axe et qui comporte deux faces de butée opposées dont chacune s'étend en regard d'une surface d'appui du pignon satellite correspondant. In order to remedy these drawbacks, the invention provides a differential of the type mentioned above, characterized in that the axial retaining means of the axis of the planet gears comprise a retaining member linked in axial translation to the middle portion of the axis and which has two opposite abutment faces, each of which extends opposite a bearing surface of the corresponding satellite pinion.
Selon d'autres caractéristiques de l'invention :
- l'organe de retenue axiale entoure au moins partiellement la portion médiane de l'axe
- l'organe de retenue axiale est réalisé sous la forme d'une pince emboîtée élastiquement sur la portion médiane de l'axe ;
- la portion médiane de l'axe est une portion de diamètre réduit délimitée axialement par deux épaulements opposés qui coopèrent avec des faces d'extrémité opposées de l'organe de retenue pour immobiliser axialement ce dernier par rapport à l'axe de rotation des pignons satellites
- les faces d'extrémité opposées de l'organe de retenue constituent les faces de butée de l'organe qui coopèrent avec les faces d'appui correspondantes des pignons satellites
- dans le cas d'un différentiel comportant une seconde paire de satellites opposés dont chacun est monté libre en rotation sur un demi-axe dont l'extrémité radiale externe est reçue dans un orifice ménagé dans une portion de la paroi du boîtier du différentiel, les axes de rotation des deux paires de satellites étant orthognaux, l'organe de retenue axiale des satellites de la première paire comporte deux fourches de retenue dont chacune est reçue dans une gorge formée sur l'extrémité radiale interne du demi-axe correspondant pour retenir axialement ce dernier.According to other characteristics of the invention:
- the axial retaining member at least partially surrounds the middle portion of the axis
- The axial retaining member is produced in the form of a clamp fitted elastically on the middle portion of the axis;
- The middle portion of the axis is a portion of reduced diameter delimited axially by two opposite shoulders which cooperate with opposite end faces of the retaining member to immobilize the latter axially with respect to the axis of rotation of the pinions satellites
- the opposite end faces of the retaining member constitute the abutment faces of the member which cooperate with the corresponding bearing faces of the planet gears
- in the case of a differential comprising a second pair of opposite satellites, each of which is mounted to rotate freely on a half-axis whose external radial end is received in an orifice formed in a portion of the wall of the differential housing, the axes of rotation of the two pairs of satellites being orthognal, the axial retaining member of the satellites of the first pair comprises two retaining forks each of which is received in a groove formed on the internal radial end of the corresponding semi-axis to retain axially the latter.

On reconnaît à la figure 1 un différentiel sphérique 10 dont le boîtier est réalisé en deux parties 12 et 14 assemblées entre elles par des liaisons filetées 16. FIG. 1 recognizes a spherical differential 10, the housing of which is produced in two parts 12 and 14 assembled together by threaded connections 16.
Le demi-boîtier 14, de gauche en considérant la figure 1, comporte la couronne d'entraînement 18 du différentiel. The half-housing 14, on the left when considering FIG. 1, comprises the drive ring 18 of the differential.
Le boîtier 10 renferme deux pignons planétaires coniques 20 et 22 liés en rotation à deux demi-arbres de sortie 24 et 26 d'axe de rotation commun X-X. The housing 10 contains two conical planetary gears 20 and 22 linked in rotation to two output half-shafts 24 and 26 with a common axis of rotation X-X.
Les planétaires 20 et 22 coopèrent avec deux pignons satellites opposés 28A et 28B qui sont montés libres en rotation autour d'un axe géométrique Y-Y perpendiculaire à l'axe X-X des planétaires. The planets 20 and 22 cooperate with two opposite satellite pinions 28A and 28B which are mounted free in rotation about a geometric axis Y-Y perpendicular to the axis X-X of the planets.
Les deux satellites 28A et 28B sont montés libres en rotation sur les portions d'extrémité opposées 30A et 30B d'un axe porte-satellites 32 qui est lui-même monté libre en rotation dans le demi-boîtier 12. The two satellites 28A and 28B are mounted free in rotation on the opposite end portions 30A and 30B of a planet carrier axis 32 which is itself mounted free in rotation in the half-housing 12.
A cet effet, les extrémités 30A et 30B sont reçues dans des perçages correspondants 34A et 34B formés dans deux portions opposées de la paroi du demi-boîtier 12. To this end, the ends 30A and 30B are received in corresponding holes 34A and 34B formed in two opposite portions of the wall of the half-housing 12.
Conformément à l'invention, l'axe porte-satellites 32 est retenu axialement, selon la direction Y-Y dans le demi-boîtier 12 au moyen d'un organe de retenue axiale 36. According to the invention, the planet carrier axis 32 is retained axially, in the direction Y-Y in the half-housing 12 by means of an axial retaining member 36.
Dans le premier mode de réalisation illustré aux figures 1 et 2, l'organe de retenue axiale 36 est réalisé sous la forme d'une pièce en tôle pliée déformable élastiquement qui est emboîtée sur la portion médiane 38 de l'axe 32. In the first embodiment illustrated in FIGS. 1 and 2, the axial retaining member 36 is produced in the form of an elastically deformable folded sheet metal part which is fitted onto the middle portion 38 of the axis 32.
La portion 38 est dans ce cas une portion de diamètre réduit délimité axialement par deux épaulements 40A et 40B. The portion 38 is in this case a portion of reduced diameter delimited axially by two shoulders 40A and 40B.
La pièce 36, qui est réalisée sous la forme d'une pince qui présente en section transversale un profil qui entoure la portion médiane 38, est délimitée axialement par deux surfaces d'extrémités opposées 42A et 42B qui s'étendent dans des plans parallèles perpendiculaires à l'axe Y-Y. The part 36, which is made in the form of a clamp which has in cross section a profile which surrounds the middle portion 38, is delimited axially by two opposite end surfaces 42A and 42B which extend in parallel perpendicular planes to the YY axis.
Les surfaces d'extrémités 42A et 42B coopèrent avec les épaulements 40A et 40B, pour immobiliser axialement l'organe de retenue 36 par rapport à l'axe 32. The end surfaces 42A and 42B cooperate with the shoulders 40A and 40B, in order to immobilize the retaining member 36 axially with respect to the axis 32.
Les surfaces d'extrémité opposées 42A et 42B de l'organe de retenue 36 coopèrent également avec les flancs radiaux 44A et 44B des pignons satellites 28A et 28B qui constituent des surfaces d' appui pour les surfaces d'extrémité 42A et 42B. The opposite end surfaces 42A and 42B of the retaining member 36 also cooperate with the radial sides 44A and 44B of the planet gears 28A and 28B which constitute bearing surfaces for the end surfaces 42A and 42B.
Ainsi, l'axe 32 est maintenu axialement dans le boîtier 10 par coopération des surfaces d'extrémité 42A et 42B qui viennent en butée contre les surfaces d'appui correspondantes 44A et 44B. Thus, the axis 32 is held axially in the housing 10 by cooperation of the end surfaces 42A and 42B which abut against the corresponding bearing surfaces 44A and 44B.
Dans la variante illustrée à la figure 3, l'axe 32 est un axe de diamètre constant et l'organe de retenue 36 doit dans ce cas être monté serré sur la portion médiane 38 de manière à être immobilisé axialement par rapport à l'axe 32. In the variant illustrated in Figure 3, the axis 32 is an axis of constant diameter and the retaining member 36 must in this case be mounted tight on the middle portion 38 so as to be immobilized axially relative to the axis 32.
On décrira maintenant les variantes de réalisation illustrées aux figures 4 à 8. The variant embodiments illustrated in FIGS. 4 to 8 will now be described.
Dans ces modes de réalisation, le boîtier 10 renferme une seconde paire de satellites 46C et 46D. In these embodiments, the housing 10 contains a second pair of satellites 46C and 46D.
Les satellites 46C et 46D sont montés libres en rotation autour d'un axe géométrique Z-Z qui est perpendiculaire aux axes X-X et Y-Y. The satellites 46C and 46D are mounted free to rotate about a geometric axis Z-Z which is perpendicular to the axes X-X and Y-Y.
Chaque satellite 46C, 46D est monté libre en rotation autour d'un demi-axe correspondant 48C, 48D dont l'extrémité radiale externe 50C, 50D est montée libre en rotation dans un perçage correspondant 52C, 52D formé dans des portions correspondantes du demi-boîtier 12. Each satellite 46C, 46D is mounted free in rotation around a corresponding half-axis 48C, 48D whose external radial end 50C, 50D is mounted free in rotation in a corresponding hole 52C, 52D formed in corresponding portions of the half housing 12.
Conformément à l'invention, l'organe de retenue axiale 36 est réalisé sous la forme d'une pièce unique qui assure simultanément la retenue axiale des satellites 28A et 28B de la première paire et des satellites 46C et 46D de la seconde paire. According to the invention, the axial retaining member 36 is produced in the form of a single piece which simultaneously ensures the axial retaining of the satellites 28A and 28B of the first pair and of the satellites 46C and 46D of the second pair.
Comme dans le cas des modes de réalisation des figures 1 à 3, l'organe de retenue 36, qui est ici réalisé sous la forme d'une noix ou croisillon, comporte une portion centrale en deux demi-parties 54A et 54B qui entoure et chevauche la portion médiane de diamètre réduit 38 de l'axe 32 des pignons 28A et 28B. As in the case of the embodiments of FIGS. 1 to 3, the retaining member 36, which is here produced in the form of a nut or crosspiece, comprises a central portion in two half-parts 54A and 54B which surrounds and overlaps the middle portion of reduced diameter 38 of the axis 32 of the pinions 28A and 28B.
Les portions 54A et 54B sont délimitées axialement par des faces d'extrémité opposées 42A et 42B qui coopèrent avec les faces radiales en vis-à-vis 44A et 44B des satellites 20A et 20B. The portions 54A and 54B are delimited axially by opposite end faces 42A and 42B which cooperate with the radial faces opposite 44A and 44B of the satellites 20A and 20B.
Selon la direction perpendiculaire, l'organe de retenue 36 comporte deux fourches 56C et 56D agencées symétriquement de part et d'autre des portions 54A et 54B, qui sont reçues chacune respectivement dans une gorge 58C, 58D formée au voisinage de l'extrémité radiale interne du demi-axe correspondant 50C, 50D. In the perpendicular direction, the retaining member 36 comprises two forks 56C and 56D arranged symmetrically on either side of the portions 54A and 54B, which are each received respectively in a groove 58C, 58D formed in the vicinity of the radial end internal of the corresponding semi-axis 50C, 50D.
L'organe de retenue axiale des quatre satellites peut ainsi être mis en place simultanément sur la portion de diamètre réduit 38 et autour des extrémités radiales internes des demi-axes 50C et 50D en venant enfourcher ces éléments lors de sa mise en place, le boîtier 10 étant ouvert depuis la gauche en considérant la figure 4. The axial retaining member of the four satellites can thus be put in place simultaneously on the reduced diameter portion 38 and around the internal radial ends of the half-axes 50C and 50D by straddling these elements when it is put in place, the housing 10 being open from the left considering FIG. 4.
Dans le mode de réalisation illustré aux figures 4 à 6, l'organe de retenue axiale 36 est réalisé sous la forme d'une pièce massive usinée tandis que, dans le mode de réalisation illustré aux figures 7 et 8, l'organe de retenue 36 dont la conception générale est identique est réalisé sous la forme d'une pièce en tôle découpée et emboutie. In the embodiment illustrated in FIGS. 4 to 6, the axial retaining member 36 is produced in the form of a solid machined part while, in the embodiment illustrated in FIGS. 7 and 8, the retaining member 36, the general design of which is identical, is produced in the form of a cut and stamped sheet metal part.
