Abstract
Description
La présente invention concerne un synchroniseur pour un pignon monté libre en rotation sur un arbre. The present invention relates to a synchronizer for a pinion mounted freely in rotation on a shaft.
Elle s'applique plus particulièrement à la fabrication de boîtes de vitesses pour véhicule automobile. It applies more particularly to the manufacture of gearboxes for a motor vehicle.
On connaît déjà dans l'état de la technique un synchroniseur pour pignon monté libre en rotation sur un arbre, comprenant un baladeur de commande à colonnettes et des surfaces tronconiques de friction complémentaires liées en rotation, respectivement, avec le baladeur et le pignon. There is already known in the prior art a synchronizer for a pinion mounted freely in rotation on a shaft, comprising a sliding guide player with balusters and frustoconical surfaces of complementary friction linked in rotation, respectively, with the sliding gear and the pinion.
Le baladeur comporte une couronne dentée de crabotage destinée à coopérer avec une denture de crabotage complémentaire solidaire du pignon. The player has a dog clutch ring intended to cooperate with complementary dog clutch teeth fixed to the pinion.
Dans un tel synchroniseur à colonnettes, la couronne de crabotage est disposée radialement entre les surfaces coniques de friction et l'axe de l'arbre. Le diamètre de la couronne de crabotage est donc relativement faible ce qui conduit à un effort d'engagement des dentures de crabotage relativement important et à des performances de transmission de couple limitées. In such a column synchronizer, the clutch gear is arranged radially between the conical friction surfaces and the axis of the shaft. The diameter of the dog clutch ring is therefore relatively small, which leads to a relatively large engagement effort of the dog clutch teeth and to limited torque transmission performance.
Des synchroniseurs à colonnettes sont décrits par exemple dans US-A-3 286 801 et FR-A-2 556 437. Column synchronizers are described for example in US-A-3,286,801 and FR-A-2,556,437.
On connaît également dans l'état de la technique un synchroniseur pour un pignon monté libre en rotation sur un arbre, du type "Borg-Warner", comprenant un moyeu porté par l'arbre et lié en rotation avec celui-ci, un manchon de commande monté coulissant axialement sur le moyeu et lié en rotation avec ce dernier, le manchon étant muni d'une denture interne de crabotage destinée à coopérer, lorsque le manchon est dans une position axiale extrême d'engagement, avec des dentures complémentaires ménagées sur deux organes dentés dont le premier est porté par le moyeu et le second est lié en rotation avec le pignon, de manière à lier en rotation le moyeu et les deux organes de crabotage, et du type comprenant deux surfaces tronconiques de friction mâle et femelle ménagées sur deux organes de friction dont le premier est lié en rotation avec le moyeu, au moins dans une position du manchon de commande, et le second est lié en rotation avec le pignon, les surfaces de friction étant disposées radialement entre la denture de crabotage du manchon et l'axe de l'arbre. Also known in the prior art is a synchronizer for a pinion mounted free in rotation on a shaft, of the "Borg-Warner" type, comprising a hub carried by the shaft and linked in rotation with the latter, a sleeve. control mounted sliding axially on the hub and linked in rotation with the latter, the sleeve being provided with an internal dog clutch teeth intended to cooperate, when the sleeve is in an extreme axial engagement position, with complementary teeth formed on two toothed members, the first of which is carried by the hub and the second of which is linked in rotation with the pinion, so as to rotate the hub and the two dog clutch members, and of the type comprising two frustoconical male and female friction surfaces provided on two friction members, the first of which is linked in rotation with the hub, at least in one position of the control sleeve, and the second is linked in rotation with the pinion, the surfaces of f riction being arranged radially between the clutch teeth of the sleeve and the axis of the shaft.
Des synchroniseurs de type "Borg-Warner" sont décrits par exemple dans US-A-2 221 901 et FR-A-1 499 952. Borg-Warner synchronizers are described for example in US-A-2,221,901 and FR-A-1,499,952.
L'invention a pour but d'optimiser l'efficacité de ce dernier type de synchroniseur. The invention aims to optimize the efficiency of the latter type of synchronizer.
A cet effet l'invention a pour objet un synchroniseur du type "Borg-Warner" précité, caractérisé en ce que la surface de friction mâle est ménagée sur le premier organe de friction et converge vers le pignon, et la surface de friction femelle est ménagée dans le second organe de friction et diverge vers le moyeu. To this end, the subject of the invention is a synchronizer of the aforementioned "Borg-Warner" type, characterized in that the male friction surface is formed on the first friction member and converges towards the pinion, and the female friction surface is formed in the second friction member and diverges towards the hub.

L'invention sera mieux comprise à la lecture de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés dans lesquels
- la figure 1 est une demi-vue en coupe axiale d'un synchroniseur selon un premier mode de réalisation de l'invention ;
- les figures 2 et 3 sont des vues partielles similaires à la figure 1 montrant respectivement des synchroniseurs selon des second et troisième modes de réalisation de l'invention.The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings in which
- Figure 1 is a half view in axial section of a synchronizer according to a first embodiment of the invention;
- Figures 2 and 3 are partial views similar to Figure 1 respectively showing synchronizers according to second and third embodiments of the invention.
On a représenté sur la figure 1 un synchroniseur selon un premier mode de réalisation de l'invention, désigné par la référence générale 10. FIG. 1 shows a synchronizer according to a first embodiment of the invention, designated by the general reference 10.
Ce synchroniseur est de type double et sa structure est globalement symétrique par rapport à son plan médian M. This synchronizer is of the double type and its structure is generally symmetrical with respect to its median plane M.
Les composants doubles de ce synchroniseur sont désignés par des chiffres de référence identiques indicés
A ou B selon leur position à droite ou à gauche du plan M en considérant la figure 1.The double components of this synchronizer are designated by identical reference numerals.
A or B according to their position on the right or on the left of the plane M by considering figure 1.
On reconnaît sur cette figure un arbre 12, d'axe
X, sur lequel est fixé axialement et immobilisé en rotation un moyeu 14. De part et d'autre de ce moyeu, par rapport au plan médian M, sont disposés deux pignons 16A et 16B qui sont immobilisés axialement mais libres en rotation sur l'arbre 12.We recognize in this figure a tree 12, axis
X, on which is axially fixed and immobilized in rotation a hub 14. On either side of this hub, relative to the median plane M, are arranged two pinions 16A and 16B which are axially immobilized but free to rotate on the tree 12.
Le synchroniseur 10 comporte également un manchon de commande 18 qui est susceptible d'être déplacé axialement par rapport au moyeu 14 sous l'action d'une fourchette de commande 20 qui est reçue dans une rainure 22 ménagée dans la périphérie du manchon de commande 18. The synchronizer 10 also includes a control sleeve 18 which can be moved axially relative to the hub 14 under the action of a control fork 20 which is received in a groove 22 formed in the periphery of the control sleeve 18 .
Les différentes positions axiales du manchon 18 par rapport au moyeu 14 résultent de la coopération de moyens d'armement classiques comprenant notamment des anneaux élastiques 24A,24B et des rampes 26A,26B ménagés sur la surface interne du manchon 18. The different axial positions of the sleeve 18 relative to the hub 14 result from the cooperation of conventional arming means comprising in particular elastic rings 24A, 24B and ramps 26A, 26B formed on the internal surface of the sleeve 18.
Pour les raisons de symétrie précisées plus haut, on ne décrira, dans ce qui suit, qu'une moitié gauche ou droite du synchroniseur illustré sur la figure 1. For the reasons of symmetry specified above, only a left or right half of the synchronizer illustrated in FIG. 1 will be described in the following.
Le manchon 18 est muni d'une denture de crabotage interne 28 destinée à coopérer, lorsque ce manchon est dans une position axiale extrême d'engagement, avec des dentures complémentaires 30A,30B,32A,32B ménagées sur deux organes denté. The sleeve 18 is provided with an internal clutch teeth 28 intended to cooperate, when this sleeve is in an extreme axial position of engagement, with complementary teeth 30A, 30B, 32A, 32B formed on two toothed members.
Un premier organe denté forme une bague 34A,34B liée en rotation au moyeu 14 avec un jeu angulaire. On notera que cette bague porte l'anneau élastique correspondant 24A,24B. A first toothed member forms a ring 34A, 34B linked in rotation to the hub 14 with an angular play. It will be noted that this ring carries the corresponding elastic ring 24A, 24B.
Le second organe denté est délimité par un prolongement axial 36A,36B du pignon correspondant. The second toothed member is delimited by an axial extension 36A, 36B of the corresponding pinion.
Lorsque le manchon 18 est dans sa position axiale extreme d'engagement, il lie en rotation le moyeu 14, le pignon 16A,16B et la bague 34A,34B. When the sleeve 18 is in its extreme axial engagement position, it rotatably links the hub 14, the pinion 16A, 16B and the ring 34A, 34B.
Le synchroniseur 10 comporte en outre au moins deux surfaces tronconiques de friction mâle 38A,38B et femelle 40A,40B. La surface de friction mâle 38A,38B est ménagée sur un organe de friction formant un prolongement axial 42A,42B du coulisseau 34A,34B et converge vers le pignon correspondant 16A,16B. La surface de friction femelle 40A,40B est ménagée dans un second organe de friction constitué par une douille conique 44A,44B liée en rotation, de façon connue en soi, avec le pignon 16A,16B correspondant. La surface de friction femelle 40A,40B diverge vers le moyeu 14. The synchronizer 10 further comprises at least two frustoconical male friction surfaces 38A, 38B and female 40A, 40B. The male friction surface 38A, 38B is formed on a friction member forming an axial extension 42A, 42B of the slide 34A, 34B and converges towards the corresponding pinion 16A, 16B. The female friction surface 40A, 40B is formed in a second friction member constituted by a conical sleeve 44A, 44B linked in rotation, in a manner known per se, with the corresponding pinion 16A, 16B. The female friction surface 40A, 40B diverges towards the hub 14.
La douille conique 44A,44B est logée dans un évidement annulaire 46A,46B ménagé dans le prolongement axial 36A,368 du pignon correspondant, de façon que la denture 32A,32B du second organe denté entoure cet évidement et la douille 44A,44B. The conical bush 44A, 44B is housed in an annular recess 46A, 46B formed in the axial extension 36A, 368 of the corresponding pinion, so that the toothing 32A, 32B of the second toothed member surrounds this recess and the bush 44A, 44B.
On notera donc que les surfaces tronconiques de friction 38A,38B,40A,40B sont disposées radialement entre les dentures de crabotage 28,30A,30B,32A,32B et l'axe X de l'arbre 12. It will therefore be noted that the frustoconical friction surfaces 38A, 38B, 40A, 40B are arranged radially between the interconnection teeth 28.30A, 30B, 32A, 32B and the axis X of the shaft 12.
Sur la figure 1, on a également représenté une douille conique de friction supplémentaire 48A,48B, liée en rotation avec la bague 34A,34B. Cette douille supplémentaire 48A,48B est intercalée entre la douille précédente 44A,44B et un contour de l'évidement 46A,46B de forme complémentaire à cette douille supplémentaire. In Figure 1, there is also shown an additional conical friction sleeve 48A, 48B, linked in rotation with the ring 34A, 34B. This additional socket 48A, 48B is interposed between the previous socket 44A, 44B and a contour of the recess 46A, 46B of shape complementary to this additional socket.
Dans l'exemple illustré sur la figure 1, la douille supplémentaire 48A,48B est délimitée, comme l'autre douille 44A,44B, par des surfaces internes et externes tronconiques divergeant vers le moyeu 14. In the example illustrated in FIG. 1, the additional socket 48A, 48B is delimited, like the other socket 44A, 44B, by frustoconical internal and external surfaces diverging towards the hub 14.
En variante, la surface externe de la douille supplémentaire 48A,48B et le contour complémentaire à cette surface de l'évidement 46A,46B peuvent être cylindriques, la friction s'effectuant alors sur les deux surfaces tronconiques, externe et interne, de la douille 44A,44B. As a variant, the external surface of the additional sleeve 48A, 48B and the contour complementary to this surface of the recess 46A, 46B may be cylindrical, the friction then taking place on the two frustoconical surfaces, external and internal, of the sleeve 44A, 44B.
Sur la figure 2, on a représenté un second mode de réalisation du synchroniseur 10 selon l'invention. In Figure 2, there is shown a second embodiment of the synchronizer 10 according to the invention.
Dans ce cas, le second organe de crabotage 36A est fabriqué séparément du pignon 16A, par exemple par découpage fin d'une tôle, puis est fixé de façon connue en soi sur le pignon. In this case, the second clutch device 36A is manufactured separately from the pinion 16A, for example by fine cutting of a sheet, then is fixed in a manner known per se to the pinion.
Sur la figure 3, on a représenté un troisième mode de réalisation du synchroniseur 10 selon l'invention. In Figure 3, there is shown a third embodiment of the synchronizer 10 according to the invention.
Dans ce cas, le second organe denté et le second organe de friction sont délimités par le même prolongement axial 36A du pignon 16A. In this case, the second toothed member and the second friction member are delimited by the same axial extension 36A of the pinion 16A.
La surface tronconique de friction femelle 40A est constituée par le contour de l'évidement 46A. The frustoconical female friction surface 40A is formed by the contour of the recess 46A.
L'invention comporte de nombreux avantages. The invention has many advantages.
La denture de crabotage 28 du manchon de commande 18 a un diamètre relativement important permettant de minimiser l'effort d'engagement de cette denture 28 dans les dentures complémentaires 30A,30B,32A,32B et d'optimiser la transmission de couple entre l'arbre et le pignon. The dog clutch teeth 28 of the control sleeve 18 have a relatively large diameter making it possible to minimize the engagement force of this teeth 28 in the complementary teeth 30A, 30B, 32A, 32B and to optimize the transmission of torque between the tree and pinion.
La surface tronconique de friction femelle, ménagée dans le pignon de façon à être intercalée radialement entre la denture de crabotage de ce pignon et l'axe de l'arbre, permet d'optimiser l'efficacité du synchroniseur. En effet, le pignon portant la surface tronconique femelle est allégé par rapport au cas classique où ce pignon porte par un prolongement axial la surface tronconique mâle, ce qui réduit l'inertie du pignon. De plus, le fait de ménager la surface de friction femelle dans le pignon permet d'augmenter le diamètre moyen de cette surface par rapport à un synchroniseur classique dans lequel cette surface femelle est portée par le moyeu, et par suite d'accroître le couple d'entraînement par frottement du pignon avant crabotage. The frustoconical female friction surface, formed in the pinion so as to be interposed radially between the clutch teeth of this pinion and the axis of the shaft, makes it possible to optimize the efficiency of the synchronizer. Indeed, the pinion carrying the female frustoconical surface is lightened compared to the classic case where this pinion carries by an axial extension the male frustoconical surface, which reduces the inertia of the pinion. In addition, the fact of providing the female friction surface in the pinion makes it possible to increase the average diameter of this surface compared to a conventional synchronizer in which this female surface is carried by the hub, and consequently to increase the torque. drive by friction of the pinion before clutching.
