L'invention sera mieux comprise, et d'autres buts, caractéristiques, 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 : 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. The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which will follow with reference to the accompanying drawings given solely by way of example illustrating an embodiment. of the invention and in which:
- 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 ;  - Figure 1 is a perspective view in partial section of a rotating coupling of the invention integrated with a shift cylinder shaft shift;

- la figure 3 est une vue en perspective de l'axe du vérin de fourchette de la figure 1.  - Figure 3 is a perspective view of the axis of the fork jack of 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 .  Referring to the figures, the reference numeral 1 designates a fixed tubular shaft of a shifting fork jack implanted in a casing, not shown, of a gearbox, particularly robotized, hydraulically controlled.
Un tel axe de vérin est connu en soi comme faisant partie d'un actionneur hydraulique et n'a pas besoin d'être davantage détaillé.  Such a cylinder axis is known per se as part of a hydraulic actuator and does not need to be more detailed.
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 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.  A rotating coupling assembly 2 is sealingly attached to one end of the shaft 1 and has a quick external coupling 3 for connecting the rotating external coupling assembly 2 to a hydraulic fluid supply pipe which can move through the set 2 and the axis 1.
L'ensemble formant raccord tournant 2 se présente sous la forme d'une pièce coudée à angle droit comportant 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 correspondante de cet axe.  The rotating coupling assembly 2 is in the form of a right angle bent piece having the outer connector 3 and an inner tubular section 4 housed coaxially in the axis 1 and in fluid communication with the coupling 3 to which it is connected via an outer ring gear 5 to the axis 1 and located adjacent to the corresponding free end of this axis.
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 . According to the invention, the rotating coupling assembly 2 is fixed to the axis 1 via 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 section tubular 4 of the assembly forming a rotating connection 2 so that the rider 6 axially keeps the tubular section 4 in the axis 1 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.  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.
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.  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 rotating assembly 2 when the plate forming a jumper 6 is secured to the axis 1 extending perpendicularly to the longitudinal direction of this axis.
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 .  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.  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.
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. The tubular portion 4 of the assembly forming a rotating coupling 2 has between its free end located in the axis 1 and the groove 9 of this section an O-ring 12 in sealing support in the axis 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.  As can be seen 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 angle gear 5 making it possible to connect the section 4 and the quick coupling 3 of the rotating union assembly 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.  The above-described fixing device of the invention has the advantage that the jumper plate 6 allows both on the one hand the blocking in translation with respect to the other of the axis 1 and the assembly forming a swivel connector 2 while ensuring the free rotation of the swivel assembly 2 relative to the axis 1 and secondly the attachment of the spindle 1 and the swivel assembly 2 to the housing of a gearbox with a single O-ring sealing means 12 between the tubular section 4 of the rotating coupling assembly 2 and the axis 1. Using only three elements to perform these functions, the manufacturing cost of this Fixing device is extremely reduced and the mounting 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 case to which the jumper 6 must be attached.
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 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 tight connection between a set forming a rotating coupling and a pipe for the circulation of a fluid under pressure.
