Abstract
Description
L'invention concerne un dispositif de transmission de couple pour véhicule automobile ayant au moins deux essiéux entrainés et un moteur disposé transversalement au sens de la marche avec une boute de vitesses qui entraine par l'intermédiaire d'un jeu d'engrenages à denture droite aussi bien le boîtier du différentiel de l'un des essieux qu'un arbre -intermédiaire qui peut être accouplé à la roue dentée conique menante d'un renvoi d'angle pour assurer l'entraînement en rotation d'un arbre de transmission aboutissant à l'autre essieu du véhicule. The invention relates to a torque transmission device for a motor vehicle having at least two driven axles and a motor arranged transversely to the direction of travel with a gearbox which drives via a set of spur gears. both the differential housing of one of the axles and an intermediate shaft which can be coupled to the bevel gear driving a bevel gear to ensure the rotational drive of a drive shaft leading to the other axle of the vehicle.
Dans un dispositif connu de transmission de ce genre (DE-OS 32 41 943), l'arbre intermédiaire est supporté par ses deux extrémités seulement dans un carter approprié. In a known transmission device of this kind (DE-OS 32 41 943), the intermediate shaft is supported by its two ends only in a suitable casing.
La roue dentée conique menante du renvoi d'angle est calée sur cet arbre intermédiaire à proximité immédiate de l'un des paliers tandis que, au voisinage de l'autre palier, le pignon mené du jeu d'engrenages à denture droite est monté fou sur l'arbre intermédiaire. Le pignon possède des crabots d'accouplement en rotation et peut être accouplé en rotation avec l'arbre intermédiaire au moyen d'un manchon baladeur à denture complémentaire de crabotage.Etant donné que l'arbre intermédiaire n'est supporté que par ses deux extrémités et que, par suite de la disposition du pignon conique mené du renvoi d'angle entre la roue dentée conique menante et le manchon baladeur à crabots, il existe un intervalle relativement grand entre les deux paliers de cet arbre intermédiaire, celui-ci est exposé à une flexion relativement importante qui peut conduire à une perturbation des engrènements des dentures et, aussi, en conséquence, à des bruits plus élevés. Vient s'ajouter à ceià le fait que la totalité des forces dues à l'engrènement des dentures dj renvoi d'angle doit être supportée par l'arbre intermédiaire car la roue dentée conique menante n'a pas d'appui propre.The bevel gear driving the bevel gear is fixed on this intermediate shaft in the immediate vicinity of one of the bearings while, in the vicinity of the other bearing, the driven pinion of the set of gears with straight teeth is mounted idly on the intermediate shaft. The pinion has rotational coupling dogs and can be coupled in rotation with the intermediate shaft by means of a sliding sleeve with complementary clutch gear. As the intermediate shaft is only supported by its two ends and that, as a result of the arrangement of the bevel gear driven from the bevel gear between the driving bevel gear and the sliding clutch sleeve, there is a relatively large gap between the two bearings of this intermediate shaft, it is exposed to a relatively large bending which can lead to a disturbance of the meshes of the teeth and, also, consequently, to higher noises. Added to this is the fact that all the forces due to the meshing of the teeth dj bevel gear must be supported by the intermediate shaft because the driving bevel gear does not have its own support.
On connait assurément déjà un dispositif d'entra;- nement analogue (DE-OS 33 34 905) dans lequel la roue dentée conique menante du renvoi d'angle qui est logé dans un carter particulier est supportée par les deux extrémités prolongées des deux côtés de son moyeu, dans ce même carter, et guide en rotation une des extrémités de l'arbre intermédiaire dont l'autre extrémité est supportée par une autre partie du carter. L'accouplement en rotation de l'arbre intermédiaire avec le moyeu prolongé de la roue dentée conique menante se fait à l'extérieur du carter du renvoi d'angle au moyen d'un manchon baladeur.Il en résulte alors une extension relativement grande dans le sens de l'axe de l'arbre intermédiaire ce qui a des conséquences désavantageuses pour les conditions du soutien parce que l'arbre intermédiaire est supporté dans une autre partie du carter que le mDyeu de La roue dentée conique du renvoi d'angle qui reçoit cet arbre par son autre extrémité. There is certainly already known a drive device; - similar arrangement (DE-OS 33 34 905) in which the driving bevel gear of the bevel gear which is housed in a particular casing is supported by the two ends extended on both sides of its hub, in this same casing, and guides in rotation one of the ends of the intermediate shaft whose other end is supported by another part of the casing. The coupling of the intermediate shaft in rotation with the extended hub of the driving bevel gear takes place outside the gearbox housing by means of a sliding sleeve, resulting in a relatively large extension in the direction of the axis of the intermediate shaft which has disadvantageous consequences for the conditions of the support because the intermediate shaft is supported in another part of the casing than the mDyeu of the bevel gear of the bevel gear which receives this tree by its other end.
L'invention a donc pour but de faire disparaître ces défauts et de perfectionner le dispositif de transmission défini plus hat de façon que, tout en obtenant un bon soutien de la roue dentée conique menante du renvoi d'angle et en diminuant la charge de flexion de l'arbre intermédiaire, on obtienne une rédJction de la longueur du dispo siti f dans le sens de cet arbre. The object of the invention is therefore to eliminate these faults and to improve the transmission device defined above so that, while obtaining good support for the bevel gear drive of the bevel gear and reducing the bending load. of the intermediate shaft, a reduction in the length of the available position is obtained in the direction of this tree.
Ce résultat est obtenu par l'invention grâce au fait que la roue dentée conique menante est supportée d'un câté par son moyeu dans une cloison intermédiaire et ds l'autre côté par l'arbre intermédiaire, qui a trois points d'appui, un à chacune de ses deux extrémités et un autre dans l'intervalle, dans le moyeu de La roue dentée conique menante, le moyeu portant du côté de la denture de cette roue menante des crabots d'accouplement en rotation dont la denture coplémentaire de crabotage est prévue sur un manchon baladeur calé en rotation sur t'arbre intermédiaire. This result is obtained by the invention thanks to the fact that the driving bevel gear is supported on a side by its hub in an intermediate partition and on the other side by the intermediate shaft, which has three support points, one at each of its two ends and another in the meantime, in the hub of the driving conical toothed wheel, the hub carrying on the side of the teeth of this driving wheel rotating coupling dogs, including the complementary teeth of dog clutch is provided on a sliding sleeve fixed in rotation on the intermediate shaft.
Etant donné que la roue dentée conique menante du renvoi d'angle a deux paliers, d'une part dans la cloison intermédiaire et d'autre part sur l'arbre intermédiaire, cette roue est bien soutenue et seule une partie des forces résultant de l'engrènement doit être supportée par l'arbre intermédiaire lui-même. Cet arbre intermédiaire est soutenu non seulement à ses extrémités mais aussi à peu près en son milieu à l'aide du moyeu de la roue dentée conique menante de sorte que la flexion est de prime abord notablement réduite et que l'on peut se contenter d'un arbre intermé- diaire de dimensions plus faibles.De plus, l'ensemble du dispositif est raccourci dans le sens de l'axe de l'arbre intermédiaire parce que la roue dentée conique menante du renvoi d'angle est elle-même utilisée comme une partie de l'accouplement avec l'arbre intermédiaire et qu'il suffit de prévoir la place nécessaire aux deux parties de l'accouplement qui sont de toute façon indispensables en plus de la roue dentée conique menante. Since the bevel gear driving the bevel gear has two bearings, on the one hand in the intermediate wall and on the other hand on the intermediate shaft, this wheel is well supported and only part of the forces resulting from the The meshing must be supported by the intermediate shaft itself. This intermediate shaft is supported not only at its ends but also approximately in its middle using the hub of the driving bevel gear so that the bending is at first remarkably reduced and that one can be satisfied with '' an intermediate shaft of smaller dimensions.Moreover, the entire device is shortened in the direction of the axis of the intermediate shaft because the bevel gear driving the bevel gear is itself used as a part of the coupling with the intermediate shaft and it suffices to provide the space necessary for the two parts of the coupling which are in any case essential in addition to the driving bevel gear.
La figure unique annexée montre en coupe à titre d'exemple les parties essentielles selon l'invention d'un dispositif de transmission pour. véhicules automobiles ayant au moins deux essieux entrainés. The single appended figure shows in section by way of example the essential parts according to the invention of a transmission device for. motor vehicles with at least two driven axles.
On se reportera à cette figure au cours de la description qui suit d'un mode particulier de réalisation de l'invention. Reference will be made to this figure during the following description of a particular embodiment of the invention.
Dans cet exemple, le véhicule automobile a un moteur (non représenté) monté transversalement au sens de la marche auquel est associée une boute de vitesses disposée parallèlement à l'axe. Cette boite de vitesses entraîne par l'intermédiaire de roues dentées à denture droite 1, 2, 3, 4 aussi bien le boîtier du différentiel de l'un des essieux 6 qu'un arbre intermédiaire 7. Cet arbre intermédiaire 7 peut être accouplé en rotation avec la roue dentée conique menante 8 d'un renvoi d'angle à roues coniques 8,9 dont le pignon conique de renvoi 9 fait partie intégrante d'un arbre 10 qui porte une bride 11 à laquelle est accouplée en rotation un arbre de transmission aboutissant à l'autre essieu. In this example, the motor vehicle has a motor (not shown) mounted transversely to the direction of travel with which there is associated a speed bottle arranged parallel to the axis. This gearbox drives by means of toothed wheels with straight teeth 1, 2, 3, 4 both the differential housing of one of the axles 6 and an intermediate shaft 7. This intermediate shaft 7 can be coupled in rotation with the driving bevel gear 8 of a bevel gear 8.9 whose conical bevel gear 9 is an integral part of a shaft 10 which carries a flange 11 to which is coupled a rotation shaft transmission leading to the other axle.
Comme on le voit, la roue dentée conique menante 8 du renvoi d'angle 8, 9 est supportée d'un côté dans une cloison intermédiaire 12 et, de l'autre côté, au moyen d'un palier 13 monté sur l'arbre intermédiaire 7, tandis que ce dernier possède trois points d'appui, un à chacune de ses deux extrémités et un palier lisse 14 situé sensiblement en son milieu dans le moyeu 8a de la roue dentée conique 8. Le moyeu 8a est pourvu du côté denté de la roue conique 8 de crabots 15 d'accouplement en rotation dont la denture antagoniste 16 est disposée sur un manchon baladeur 17 qui est calé en rotation avec l'arbre intermédiaire 7. As can be seen, the driving bevel gear 8 of the bevel gear 8, 9 is supported on one side in an intermediate partition 12 and, on the other side, by means of a bearing 13 mounted on the shaft intermediate 7, while the latter has three support points, one at each of its two ends and a plain bearing 14 located substantially in its middle in the hub 8a of the bevel gear 8. The hub 8a is provided on the toothed side of the bevel wheel 8 of clutch coupling dogs 15 in rotation, the opposing teeth 16 of which are disposed on a sliding sleeve 17 which is locked in rotation with the intermediate shaft 7.
Pour la clarté du dessin, les pièces du dispositif destinées à la manoeuvre du manchon baladeur 17 ne sont pas représen tées. For clarity of the drawing, the parts of the device intended for the operation of the sliding sleeve 17 are not shown.
