Description

"DISPOSITIF DE FIXATION ETANCHE D'UN RACCORD TOURNANT A UN CONDUIT DESTINE A ETRE SOLIDARISE A UNE STRUCTURE FIXE, TELLE QU'UN CARTER D'UNE BOITE DE VITESSES D'UN VEHICULE AUTOMOBILE". "DEVICE FOR THE SEALING OF A CONNECTION TURNING TO A CONDUIT INTENDED TO BE SOLIDARIZED TO A FIXED STRUCTURE, SUCH AS A CRANKCASE OF A GEARBOX OF A MOTOR VEHICLE".

La présente invention concerne un dispositif de fixation étanche d'un raccord tournant à un conduit destiné à être solidarisé à une structure fixe et à travers lesquels peut circuler un fluide. The present invention relates to a device for sealing a rotating connection to a conduit intended to be secured to a fixed structure and through which a fluid can flow.

Elle s'applique en particulier mais de manière non limitative à des boîtes de vitesses robotisées à commande hydraulique où le passage de vitesses s'effectue notamment à l'aide d'actionneurs hydrauliques de structure spécifique pouvant être implantés aisément dans les carters de ces boîtes de vitesses. Chaque actionneur hydraulique comprend un vérin intégré à un axe fixe de déplacement d'une fourchette de passage de vitesse et se pose alors le problème de raccorder l'axe de vérin de fourchette à un tuyau d'alimentation en fluide hydraulique. Il est connu par le document EP 0 072 889 de raccorder l'une dans l'autre deux parties tubulaires d'un système hydraulique pour constituer un joint tournant. Cependant, ce genre de raccord hydraulique tournant étanche est d'une structure extrêmement complexe et, en tout cas, n'est pas du tout adapté pour être implanté dans une boîte de vitesses pour rendre cette dernière la plus compacte possible. La présente invention a pour but de proposer un raccord tournant étanche qui peut être directement intégré de manière simple à un axe de vérin de fourchette pour loger cet ensemble dans une boîte de vitesses de façon la plus compacte possible. A cet effet, selon l'invention, le dispositif de fixation étanche d'un raccord tournant à un conduit destiné à être solidarisé à une structure fixe et à travers lesquels peut circuler un fluide, tel qu'un fluide hydraulique, est caractérisé en ce qu'il comprend un cavalier monté sur le conduit, destiné à solidariser le conduit à la structure fixe et dont les deux branches sont introduites respectivement dans deux fentes traversant la paroi du conduit pour faire saillie partiellement à l'intérieur du conduit et s'engager dans une gorge d'un tronçon tubulaire du raccord tournant logé dans le conduit de manière que le cavalier maintienne axialement le tronçon tubulaire dans le conduit et autorise une libre rotation de ce tronçon relativement au conduit. De préférence, le cavalier est en forme de plaque rigide disposée perpendiculairement à l'axe longitudinal du conduit et comportant deux oreilles externes formant les branches du cavalier et pouvant être fixées à la structure fixe. Les oreilles de ce cavalier comportent chacune un perçage de passage d'une vis de fixation à la structure fixe. It applies in particular but in a nonlimiting manner to robotized gearboxes with hydraulic control where the shifting is carried out in particular using hydraulic actuators of specific structure that can be easily implanted in the housings of these boxes. speeds. Each hydraulic actuator comprises a jack integrated in a fixed axis of movement of a shift fork and then the problem is connected to connect the fork cylinder shaft to a hydraulic fluid supply pipe. It is known from document EP 0 072 889 to connect one another in the other two tubular parts of a hydraulic system to form a rotary joint. However, this type of hydraulic rotating tight fitting is of an extremely complex structure and, in any case, is not at all adapted to be implanted in a gearbox to make the latter as compact as possible. The object of the present invention is to propose a sealed rotary coupling which can be directly integrated in a simple manner with a fork jack axis in order to house this assembly in a gearbox in the most compact manner possible. For this purpose, according to the invention, the device for sealing a rotating connection to a conduit intended to be secured to a fixed structure and through which a fluid, such as a hydraulic fluid, can be circulated is characterized in that it comprises a jumper mounted on the conduit, intended to secure the conduit to the fixed structure and whose two branches are respectively introduced into two slots through the wall of the conduit to partially project inside the conduit and engage in a groove of a tubular section of the rotary coupling housed in the conduit so that the rider axially maintains the tubular section in the conduit and allows free rotation of this section relative to the conduit. Preferably, the jumper is in the form of a rigid plate disposed perpendicularly to the longitudinal axis of the conduit and having two outer ears forming the arms of the rider and can be fixed to the fixed structure. The ears of this rider each comprise a piercing passage of a fixing screw to the fixed structure.

Avantageusement, le tronçon tubulaire du raccord tournant comporte entre son extrémité libre située dans le conduit et la gorge de ce tronçon un joint torique en appui d'étanchéité dans le conduit. Les deux fentes du conduit sont diamétralement 25 opposées et situées à proximité d'une extrémité libre du conduit. Le raccord tournant peut être extérieurement relié à un tuyau d'alimentation en fluide. Le raccord tournant comporte une partie coudée 30 extérieurement solidaire du tronçon tubulaire logé dans le conduit et pouvant être relié au tuyau d'alimentation en fluide. Dans une application préférée, le conduit est un axe de vérin de fourchette de passage de vitesses dans 35 une boîte de vitesses à commande hydraulique pour un véhicule automobile et le cavalier est fixé dans le carter de la boîte de vitesses. Advantageously, the tubular section of the rotary coupling comprises between its free end located in the duct and the groove of this section an O-ring in sealing support in the duct. The two slots of the duct are diametrically opposed and located near a free end of the duct. The rotating union can be externally connected to a fluid supply pipe. The rotating coupling has a bent portion 30 externally secured to the tubular section housed in the conduit and can be connected to the fluid supply pipe. In a preferred application, the conduit is a gearshift cylinder shaft in a hydraulically driven gearbox for a motor vehicle and the jumper is secured in the gearbox housing.

L'invention sera mieux comprise, et d'autres buts, caracteristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels : - la figure 1 est une vue en perspective avec coupe partielle d'un raccord tournant de l'invention intégré à un axe de vérin de fourchette de passage de vitesse ; - la figure 2 est une vue en coupe suivant la ligne II-II de la figure 1 ; et - la figure 3 est une vue en perspective de l'axe du vérin de fourchette de la figure 1. En se reportant aux figures, la référence 1 désigne un axe tubulaire fixe de vérin de fourchette de passage de vitesses implanté dans un carter, non représenté, d'une boîte de vitesses, notamment robotisée, à commande hydraulique. Un tel axe de vérin est connu en soi comme faisant 20 partie d'un actionneur hydraulique et n'a pas besoin d'être davantage détaillé. Un ensemble formant raccord tournant 2 est fixé de manière étanche à l'une des extrémités de l'axe 1 et comporte un raccord externe rapide 3 permettant de 25 brancher l'ensemble formant raccord externe tournant 2 à un tuyau d'alimentation en fluide hydraulique pouvant circuler à travers l'ensemble 2 et l'axe 1. L'ensemble formant raccord tournant 2 se présente sous la forme d'une pièce coudée à angle droit comportant 30 le raccord externe 3 et un tronçon tubulaire interne 4 logé coaxialement dans l'axe 1 et en communication de fluide avec le raccord 3 auquel il est raccordé par l'intermédiaire d'un renvoi d'angle 5 extérieur à l'axe 1 et situé de manière adjacente à l'extrémité libre 35 correspondante de cet axe. Selon l'invention, l'ensemble formant raccord tournant 2 est fixé à l'axe 1 par l'intermédiaire d'un cavalier 6 monté sur l'axe 1 et dont les deux branches 7 sont introduites respectivement dans deux fentes 8 traversant la paroi de l'axe 1 pour faire saillie partiellement à l'intérieur de cet axe et s'engager dans une gorge 9 du tronçon tubulaire 4 de l'ensemble formant raccord tournant 2 de manière que le cavalier 6 maintienne axialement le tronçon tubulaire 4 dans l'axe 1 et autorise une libre rotation de ce tronçon relativement à cet axe. The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly in the following explanatory description made with reference to the accompanying drawings given solely by way of example illustrating an embodiment. of the invention and in which: - Figure 1 is a perspective view in partial section of a rotary coupling of the invention integrated with a shift cylinder shaft shift; - Figure 2 is a sectional view along the line II-II of Figure 1; and FIG. 3 is a perspective view of the axis of the fork jack of FIG. 1. Referring to the figures, the reference numeral 1 denotes a fixed tubular axis of a shifter fork jack implanted in a casing, not shown, a gearbox, including robotic, hydraulically controlled. Such a cylinder axis is known per se as part of a hydraulic actuator and need not be further detailed. A rotating coupling assembly 2 is sealingly attached to one end of the shaft 1 and has a quick external connector 3 for connecting the rotating external coupling assembly 2 to a hydraulic fluid supply pipe. The rotary coupling assembly 2 is in the form of a right angle bent piece having the outer connector 3 and an inner tubular section 4 coaxially housed in the housing. 1 axis and in fluid communication with the connector 3 to which it is connected via an angle of reference 5 outside the axis 1 and located adjacent to the corresponding free end 35 of this axis. According to the invention, the assembly forming a rotating connection 2 is fixed to the axis 1 by means of a jumper 6 mounted on the axis 1 and whose two branches 7 are respectively introduced into two slots 8 passing through the wall of the axis 1 to project partially inside this axis and engage in a groove 9 of the tubular portion 4 of the assembly forming a rotating connection 2 so that the rider 6 axially maintains the tubular section 4 in the 1 axis and allows free rotation of this section relative to this axis.

En outre, le cavalier 6 est destiné à être fixé à une partie correspondante dans le carter de la boîte de vitesses afin d'immobiliser l'axe 1 dans ce carter. De préférence, le cavalier 6 se présente sous la forme d'une plaque rigide comportant entre ses deux branches 7 une découpe centrale 10 sensiblement en forme de U dont les deux bords latéraux sont engagés respectivement dans les deux fentes diamétralement opposées 8 de l'axe 1 et dans la gorge 9 du tronçon tubulaire 4 de l'ensemble formant raccord tournant 2 lorsque la plaque formant cavalier 6 est solidarisée à l'axe 1 en s'étendant perpendiculairement à la direction longitudinale de cet axe. L'encastrement des deux fentes 8 de l'axe 1 entre les deux branches 7 du cavalier 6 s'effectue avec jeu et ces deux branches s'engagent dans la gorge 9 du tronçon tubulaire 4 pour permettre d'immobiliser cet axe en translation relativement au cavalier 6 qui est ensuite fixé à la partie correspondante du carter de la boîte de vitesses. In addition, the jumper 6 is intended to be fixed to a corresponding portion in the housing of the gearbox to immobilize the axis 1 in this housing. Preferably, the jumper 6 is in the form of a rigid plate having between its two branches 7 a substantially U-shaped central cutout 10 whose two lateral edges are respectively engaged in the two diametrically opposite slots 8 of the axis. 1 and in the groove 9 of the tubular section 4 of the assembly forming a rotary coupling 2 when the forming plate 6 is secured to the axis 1 extending perpendicularly to the longitudinal direction of this axis. The recessing of the two slots 8 of the axis 1 between the two branches 7 of the jumper 6 is performed with clearance and these two branches engage in the groove 9 of the tubular section 4 to allow to immobilize this axis in translation relatively to the rider 6 which is then attached to the corresponding part of the gearbox housing.

La plaque du cavalier 6 comporte deux oreilles externes définissant les deux branches 7 du cavalier 6 et qui comportent chacune au moins un perçage 11 permettant le passage d'une vis, non représentée, de fixation du cavalier 6 à la paroi correspondante du carter de la boîte de vitesses. Le tronçon tubulaire 4 de l'ensemble formant raccord tournant 2 comporte entre son extrémité libre située dans l'axe 1 et la gorge 9 de ce tronçon un joint torique 12 en appui d'étanchéité dans l'axe 1. Comme cela ressort de la figure 3, les deux fentes diamétralement opposées 8 de l'axe 1 sont situées à proximité de l'extrémité libre de l'axe 1 adjacente au renvoi d'angle 5 permettant de raccorder en équerre le tronçon 4 et le raccord rapide 3 de l'ensemble formant raccord tournant 2. Le dispositif de fixation ci-dessus décrit de l'invention a pour avantage que la plaque formant cavalier 6 permet à la fois d'une part le blocage en translation l'un par rapport à l'autre de l'axe 1 et de l'ensemble formant raccord tournant 2 tout en assurant la libre rotation de l'ensemble formant raccord tournant 2 relativement à l'axe 1 et d'autre part la fixation de l'axe 1 et de l'ensemble formant raccord tournant 2 dans le carter de boîte de vitesses avec un moyen d'étanchéité simple à joint torique 12 entre le tronçon tubulaire 4 de l'ensemble formant raccord tournant 2 et l'axe 1. En utilisant que trois éléments pour assurer ces fonctions, le coût de fabrication de ce dispositif de fixation est extrêmement réduit et le montage de ce dispositif est extrêmement rapide. En outre, la conception simple de ce dispositif conduit également à une réalisation simple de la partie du carter de la boîte de vitesses à laquelle doit être fixé le cavalier 6. Le dispositif de fixation de l'invention a été décrit dans l'application à une boîte de vitesses à commande hydraulique dite robotisée, mais il est bien entendu qu'il peut s'appliquer dans tout autre domaine technique nécessitant un raccordement étanche entre un ensemble formant raccord tournant et une conduite destinés à la circulation d'un fluide sous pression. The rider plate 6 has two outer ears defining the two branches 7 of the rider 6 and each having at least one hole 11 allowing the passage of a screw, not shown, for fixing the rider 6 to the corresponding wall of the housing of the gearbox. The tubular section 4 of the assembly forming a swivel connector 2 has between its free end located in the axis 1 and the groove 9 of this section an O-ring 12 in sealing engagement in the axis 1. As is apparent from FIG. 3, the two diametrically opposite slots 8 of the axis 1 are located near the free end of the axis 1 adjacent to the bevel gear 5 for connecting square section 4 and the quick connector 3 of the 2. The above-described fastening device of the invention has the advantage that the jumper plate 6 allows both the locking on the one hand in translation with respect to the other. the axis 1 and the assembly forming a rotating coupling 2 while ensuring the free rotation of the assembly forming a rotary coupling 2 relative to the axis 1 and secondly the fixing of the axis 1 and the assembly forming a rotating union 2 in the transmission case with a sealing means O-ring single tee 12 between the tubular portion 4 of the rotating coupling assembly 2 and the axis 1. Using only three elements to perform these functions, the manufacturing cost of this fastener is extremely small and the assembly of this device is extremely fast. In addition, the simple design of this device also leads to a simple embodiment of the part of the gearbox housing to which the jumper 6 must be attached. The fastening device of the invention has been described in the application to a gearbox with hydraulic control called robotic, but it is understood that it can be applied in any other technical field requiring a sealed connection between a rotating assembly and a pipe for the circulation of a fluid under pressure .
