Description

"Agencement pour la connexion d'un réservoir d'alimentation en fluide de frei nage" L'invention concerne un agencement pour la connexion d'un réservoir d'alimentation en fluide de freinage à un maître- cylindre de freinage de véhicule automobile. L'invention concerne plus particulièrement un agencement pour la connexion d'un réservoir d'alimentation en fluide de freinage à un maître-cylindre longitudinal de freinage de véhicule automobile, du type dans lequel au moins une pipe d'alimentation inférieure liée au réservoir est reçue dans un perçage d'alimentation complémentaire du maître-cylindre et d u type dans lequel des moyens d'immobilisation verticale sont interposés entre la pipe et le maître-cylindre. On connaît de nombreux exemples d'agencements de ce type. Il s'agit pour la plupart d'agencement pour lesquels le réservoir d'alimentation comporte la pipe d'alimentation et est fixé directement au réservoir. Conventionnellement, le réservoir comporte deux pipes d'alimentation associée chacune à l'alimentation d'une des deux cambres du maître-cylindre. Les pipes sont emboîtées "Arrangement for the connection of a brake fluid supply reservoir" The invention relates to an arrangement for the connection of a brake fluid supply reservoir to a motor vehicle brake master cylinder. The invention relates more particularly to an arrangement for the connection of a brake fluid supply reservoir to a longitudinal master cylinder for braking a motor vehicle, of the type in which at least one lower supply pipe connected to the reservoir is received in a complementary supply bore of the master cylinder and of the type in which vertical immobilization means are interposed between the pipe and the master cylinder. Numerous examples of arrangements of this type are known. For the most part, this is an arrangement for which the supply tank includes the supply pipe and is fixed directly to the tank.

• directement dans le maître-cylindre et le réservoir est verrouillé par l'intermédiaire d'une goupille qui traverse le réservoir et un perçage du maître-cylindre. Cette conception ne permet pas d'automatiser de manière aisée le montage du réservoir sur le maître-cylindre car la mise en place de la goupille s'avère être une opération particulièrement délicate. Par ailleurs, cette conception ne permet pas la mise en place standardisée de réservoirs de types différents. Chaque réservoir doit comporter des buses adaptées et de ce fait, la conception d'un tel réservoir, généralement réalisé par moulage d'un matériau plastique, se révèle particulièrement onéreuse. Par ailleurs, dans le cadre de la fabrication du maître- cylindre, il peut être souhaitable de relier le maître-cylindre à un réservoir indépendant. Or la conception conventionnelle précitée ne permet pas de brancher rapidement un tube issu d'un réservoir indépendant dans le perçage d'alimentation du maître-cylindre. Enfin, le démontage du réservoir nécessite d'effectuer une purge du circuit de freinage. En effet, le démontage du réservoir prive le maître-cylindre de son alimentation en fluide de freinage et peut entraîner l'introduction de bulles d'air dans le circuit de freinage. L'invention permet de remédier à tous ces inconvénients en proposant un agencement permettant un montage rapide et standardisé d'un réservoir, qu'il s'agisse d'un réservoir indépendant ou d'un réservoir fixé au maître-cylindre. Dans ce but, l'invention propose un agencement du type décrit précédemment, caractérisé en ce qu'il comporte une embase intermédiaire, qui est reliée au réservoir par au moins une buse, qui comporte la pipe d'alimentation , et qu i est susceptible d'être descendue verticalement sur le maître-cylind re puis immobilisée sur le maître-cylindre par l'intermédiaire de moyens d'immobilisation verticale coopérant par encliquetage direct avec le maître-cylindre, pour permettre une fixation rapide de la pipe sur le maître-cylindre. Selon d'autres caractéristiques de l'invention : - le réservoir est fixé sur l'embase, la buse de l'embase étant reçue dans le réservoir et l'embase étant interposée entre le réservoir et le maître-cylindre, - la fixation d u réservoir sur l'embase est compatible avec différents types de réservoirs, pour permettre le montage de différents réservoirs sur l'embase, - en variante, le réservoir est indépendant de l'embase, la buse de l'embase étant reliée à une buse d u réservoir par l'intermédiaire d'un tube indépendant, - les moyens d'immobilisation verticale comportent au moins deux bras qui s'étendent sensiblement verticalement vers le maître-cylindre à partir d'un bord longitudinal de l'embase et un bras qui s'étend sensiblement verticalement vers le maître- cylindre à partir d'un bord longitudinal opposé de l'embase, des premier moyens de verrouillage étant disposés à proximité des extrémités des bras pour coopérer avec des seconds moyens de verrouillage portés par le maître-cylindre, - les bras sont flexibles transversalement de manière que, lorsque l'embase est descendue sur le maître-cylindre, les bras s'écartent au passage d'ergots transversaux du maître-cylindre formant les seconds moyens de verrouillage, puis se rétractent lorsque des perçages transversaux agencés à proximité des extrémités des bras et formant les premiers moyens de verrouillage reçoivent les ergots transversaux, - les bras comportent des gouttières de guidage des ergots qui sont formées dans des faces verticales intérieures des bras entre leurs extrémités et les perçages transversaux et qui sont destinées à coopérer avec des chanfreins supérieurs desdits ergots pour faciliter l'écartement des bras, - les bras sont réalisés en un matériau plastique. - l'embase comporte des moyens de préhension pour le montage de l'embase sur le maître-cylindre. - les bords longitudinaux opposés de l'embase sont conformés en empreintes formant une queue d'aronde pour permettre leur préhension par deux bras conformes d'un robot de montage automatisé. L'invention concerne aussi un procédé de montage d'une embase de réservoir sur un maître-cylindre du type selon un agencement du type décrit précédemment, caractérisé en ce qu'il comporte : - une première étape au cours de laquelle deux bras d'un robot de montage sont agencés chacun en regard d'une empreinte de la queue d'aronde de l'embase, - une deuxième étape au cours de laquelle les bras sont serrés sur l'embase de manière que l'extrémité de chacun des bras pénètre dans l'empreinte du bord correspondant de l'embase, - une troisième étape au cours de laquelle les bras positionnent l'embase au dessus du maître-cylindre, la pipe d'alimentation en regard du perçage d'alimentation , - une quatrième étape au cours de laquelle les bras descendent l'embase sur le maître-cylindre jusqu'à l'encliquetage des moyens d'immobilisation verticale, - une cinquième et dernière étape au cours de laquelle les bras sont écartés de l'embase. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective éclatée d'un agencement selon l'invention ; - le figure 2 est une vue en perspective illustrant la première étape du procédé selon l'invention ; - la figure 3 est une vue en perspective illustrant les deuxième et troisième étape du procédé selon l'invention ; - les figures 4 et 5 sont des vues en perspective illustrant la quatrième étape du procédé selon l'invention ; - la figure 6 est une vue en perspective illustrant la cinq uième étape du procédé selon l'invention ; - la figure 7 est une vue en perspective de détail du dessous de l'agencement au cours de la quatrième étape d u procédé ; - la figure 8 est une vue en perspective éclatée d'un second agencement selon l'invention. Dans la description qui va suivre, des chiffres de référence identiques désignent des pièces identiques ou ayant des fonctions similaires. Par convention, les termes "avant", "arrière", supérieur" , "inférieur" désignent respectivement des éléments ou des positions orientés respectivement vers la gauche, la droite, le haut, ou le bas des figures 1 à 8. On a représenté à la figure 1 l'ensemble d'un agencement • directly in the master cylinder and the tank is locked by means of a pin which crosses the tank and a hole in the master cylinder. This design does not easily automate the mounting of the reservoir on the master cylinder because the installation of the pin turns out to be a particularly delicate operation. Furthermore, this design does not allow the standardized installation of tanks of different types. Each tank must have suitable nozzles and therefore the design of such a tank, generally produced by molding a plastic material, proves to be particularly expensive. Furthermore, in the context of the manufacture of the master cylinder, it may be desirable to connect the master cylinder to an independent tank. However, the aforementioned conventional design does not allow rapid connection of a tube from an independent reservoir in the supply bore of the master cylinder. Finally, dismantling the tank requires performing a bleeding of the brake circuit. In fact, dismantling the reservoir deprives the master cylinder of its supply of braking fluid and can cause air bubbles to be introduced into the braking circuit. The invention overcomes all these drawbacks by proposing an arrangement allowing rapid and standardized mounting of a tank, whether it is an independent tank or a tank fixed to the master cylinder. To this end, the invention provides an arrangement of the type described above, characterized in that it comprises an intermediate base, which is connected to the reservoir by at least one nozzle, which comprises the supply pipe, and which is susceptible to be lowered vertically on the master cylinder and then immobilized on the master cylinder by means of vertical immobilization cooperating by direct snap-fastening with the master cylinder, to allow rapid fixing of the pipe on the master- cylinder. According to other characteristics of the invention: - the reservoir is fixed on the base, the nozzle of the base being received in the reservoir and the base being interposed between the reservoir and the master cylinder, - the fixing of the tank on the base is compatible with different types of tanks, to allow mounting of different tanks on the base, - alternatively, the tank is independent of the base, the nozzle of the base being connected to a nozzle of the tank via an independent tube, - The vertical immobilization means comprise at least two arms which extend substantially vertically towards the master cylinder from a longitudinal edge of the base and an arm which extends substantially vertically towards the master cylinder from an opposite longitudinal edge of the base, first locking means being arranged near the ends of the arms to cooperate with second locking means carried by the master cylinder, - the arms are transversely flexible so that, when the base is lowered onto the master cylinder, the arms move apart when transverse lugs pass from the master cylinder forming the second locking means, then retract when transverse bores arranged near the ends of the arms and forming the first locking means receive the transverse pins, - the arms include grooves for guiding the pins which are formed in s internal vertical faces of the arms between their ends and the transverse bores and which are intended to cooperate with upper chamfers of said lugs to facilitate the spacing of the arms, - the arms are made of a plastic material. - The base includes gripping means for mounting the base on the master cylinder. - The opposite longitudinal edges of the base are shaped into indentations forming a dovetail to allow their gripping by two conforming arms of an automated assembly robot. The invention also relates to a method of mounting a tank base on a master cylinder of the type according to an arrangement of the type described above, characterized in that it comprises: - a first step during which two arms of an assembly robot are each arranged opposite an imprint of the dovetail of the base, - a second step during which the arms are tightened on the base so that the end of each of the arms enters the imprint of the corresponding edge of the base, - a third step during which the arms position the base above the master cylinder, the supply pipe opposite the supply bore, - a fourth step during which the arms descend the base on the master cylinder until the means click into place vertical immobilization, - a fifth and final step during which the arms are moved away from the base. Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which: - Figure 1 is an exploded perspective view of an arrangement according to the invention. invention; - Figure 2 is a perspective view illustrating the first step of the method according to the invention; - Figure 3 is a perspective view illustrating the second and third step of the method according to the invention; - Figures 4 and 5 are perspective views illustrating the fourth step of the method according to the invention; - Figure 6 is a perspective view illustrating the fifth step of the method according to the invention; - Figure 7 is a detailed perspective view of the underside of the arrangement during the fourth step of the method; - Figure 8 is an exploded perspective view of a second arrangement according to the invention.

10 réalisé conformément à l 'invention. De manière connue, l'agencement 10 permet la connexion d'un réservoir 12 d'alimentation en fluide de freinage à un maître- cylindre 14 longitudinal de freinage de véhicule automobile. Au moins une pipe 16 d'alimentation inférieure, qui est liée au réservoir 12, est destinée à être reçue dans un perçage 1 8 d'alimentation complémentaire du maître-cylindre 14. Des moyens 20 d'immobilisation verticale sont par ailleurs interposés entre la pipe 16 et le maître-cylindre 14. Plus particulièrement, l'agencement 10 comporte de manière conventionnelle deux pipes 16 destinées chacune à pénétrer dans un perçage 18 d'alimentation associé du maître- cylindre 14. Chaque perçage 18 est destiné à alimenter en fluide de freinage une chambre interne associée du maître-cylindre 14. U n tel maître-cylindre 14, plus communément appelé maître- cylindre "tandem", est destiné à alimenter en fluide de freinage sous pression deux circuits indépendants de freinage du véhicule dans lequel il est monté. Dans une conception conventionnelle (non représentée), le réservoir 12 porte les pipes 16. Il est par ailleurs immobilisé sur le maître-cylindre 14 par l'intermédiaire d'une goupille. Le montage d'une telle goupille est particulièrement malaisé à réaliser à une échelle industrielle. La conception selon l'invention est particulièrement avantageuse en ce qu'elle permet un montage rapide et standardisé d'un réservoir 12, qu'il s'agisse d'un réservoir 12 indépendant ou d'un réservoir 12 fixé au maître-cylindre 14. Cette conception permet de réaliser le montage du réservoir 12 de manière industrielle, c'est à dire sur une ligne de fabrication automatisée. Conformément à l'invention , l'agencement 10 comporte une embase 22 intermédiaire, qui est reliée au réservoir 12 par au moins une buse 24, qui comporte la pipe 16 d'alimentation, et qu i est susceptible d'être descendue verticalement sur le maître- cylindre 14 puis immobilisée sur le maître-cylindre 14 par l'intermédiaire de moyens 20 d'immobilisation verticale coopérant par encliquetage direct avec le maître-cylindre 14, pour permettre une fixation rapide de la pipe 16 sur le maître-cylindre 14. Comme on peut le voir sur la figure 8, dans le mode de réalisation préféré de l'invention, l'embase comporte deux buses 24 qui communiquent chacune avec une pipe 16. Plus particulièrement, le réservoir 12 est fixé sur l'embase 22, les buses 24 de l'embase étant reçues et notamment emboîtées dans le réservoir 12. L'embase 22 est interposée entre le réservoir 12 et le maître-cylindre 14. La fixation du réservoir 12 sur l'embase 14 peut être assurée par les seules buses 24. Toutefois, de manière on limitative de l'invention, tout autre mode de réalisation de cette fixation peut être envisagé. Avantageusement la fixation du réservoir 12 sur l'embase est compatible avec différents types de réservoirs 12. Cette configuration permet le montage de différents réservoirs de formes et de capacités différentes, adaptés chacun à un véhicu le particulier, sur l'embase 14. L'embase est aussi particulièrement adaptée à un montage comportant un réservoir 12 indépendant. Ainsi, en variante, le réservoir 12 peut être indépendant de l'embase 24, les buses 24 de l'embase 22 étant reliée à une buse (non représentée) d'un réservoir indépendant par l'intermédiaire d'un tube indépendant (non représenté). Un tel réservoir 12 indépendant peut par exemple être utilisé pour tester successivement plusieurs maître-cylindres 14 en débranchant simplement les tubes des buses 24 à chaque changement de maître-cylindre 14. Conformément à l'invention , les moyens d'immobilisation verticale de l'embase 22 comportent au moins deux bras 26 qui s'étendent sensiblement verticalement vers le maître-cylind re 14 à partir d'un bord 30 longitudinal de l'embase 22 et un bras 28 qui s'étend sensiblement verticalement vers le maître-cylindre 14 à partir d'un bord longitudinal 32 opposé de l'embase 22. Des premiers moyens 34 de verrouillage sont disposés à proximité des extrémités 36, 38 des bras pour coopérer avec des seconds moyens 40 de verrouillage portés par le maître-cylindre 14. Ces premiers moyens 34 et ces seconds moyens 40 seront décrits plus en détails dans la suite de la présente description . Plus particulièrement, les bras 26, 28 sont flexibles transversalement de manière que, lorsque l'embase 22 est descendue sur le maître-cylindre 14, les bras 26, 28 s'écartent au passage d'ergots 40 transversaux du maître-cylindre formant les seconds moyens de verrouillage, comme représenté à la figure 4, puis se rétractent lorsque des perçages 34 transversaux agencés à proximité des extrémités des bras et formant les premiers moyens de verrouillage reçoivent les ergots 40 transversaux, comme représenté à la figure 5. Les ergots 40 s'étendent avantageusement transversalement à partir du fût cylindrique du maître cylindre 14. Avantageusement, pour faciliter l'introduction des ergots10 produced in accordance with the invention. In known manner, the arrangement 10 allows the connection of a reservoir 12 for supplying brake fluid to a longitudinal master cylinder 14 for braking a motor vehicle. At least one lower supply pipe 16, which is linked to the reservoir 12, is intended to be received in a bore 1 8 complementary supply to the master cylinder 14. Means 20 for vertical immobilization are also interposed between the pipe 16 and the master cylinder 14. More particularly, the arrangement 10 conventionally comprises two pipes 16 each intended to penetrate a bore 18 associated with the master cylinder supply 14. Each bore 18 is intended to supply fluid braking an associated internal chamber of the master cylinder 14. A master cylinder 14, more commonly known as a "tandem" master cylinder, is intended to supply brake fluid under pressure to two independent braking circuits of the vehicle in which it has climbed. In a conventional design (not shown), the reservoir 12 carries the pipes 16. It is moreover immobilized on the master cylinder 14 by means of a pin. The mounting of such a pin is particularly difficult to achieve on an industrial scale. The design according to the invention is particularly advantageous in that it allows rapid and standardized mounting of a reservoir 12, whether it is an independent reservoir 12 or a reservoir 12 fixed to the master cylinder 14 This design makes it possible to mount the reservoir 12 of industrially, i.e. on an automated manufacturing line. According to the invention, the arrangement 10 comprises an intermediate base 22, which is connected to the reservoir 12 by at least one nozzle 24, which comprises the supply pipe 16, and which i is capable of being lowered vertically onto the master cylinder 14 then immobilized on the master cylinder 14 by means of vertical immobilization means cooperating by direct snap-fastening with the master cylinder 14, to allow rapid fixing of the pipe 16 on the master cylinder 14. As can be seen in FIG. 8, in the preferred embodiment of the invention, the base comprises two nozzles 24 which each communicate with a pipe 16. More particularly, the reservoir 12 is fixed to the base 22, the nozzles 24 of the base being received and in particular fitted into the reservoir 12. The base 22 is interposed between the reservoir 12 and the master cylinder 14. The fixing of the reservoir 12 on the base 14 can be ensured by the sole nozzles 24. However, in a limiting manner of the invention, any other embodiment of this attachment can be envisaged. Advantageously, the attachment of the reservoir 12 to the base is compatible with different types of tanks 12. This configuration allows the mounting of different reservoirs of different shapes and capacities, each adapted to a particular vehicle, on the base 14. The base is also particularly suitable for an assembly comprising an independent reservoir 12. Thus, as a variant, the reservoir 12 can be independent of the base 24, the nozzles 24 of the base 22 being connected to a nozzle (not shown) of an independent reservoir via an independent tube (not represented). Such an independent tank 12 can for example be used to successively test several master cylinders 14 by simply disconnecting the tubes of the nozzles 24 at each change of master cylinder 14. According to the invention, the means for vertical immobilization of the base 22 include at least two arms 26 which extend substantially vertically towards the master- re cylinder 14 from a longitudinal edge 30 of the base 22 and an arm 28 which extends substantially vertically towards the master cylinder 14 from an opposite longitudinal edge 32 of the base 22. First means 34 locking are arranged near the ends 36, 38 of the arms to cooperate with second locking means 40 carried by the master cylinder 14. These first means 34 and these second means 40 will be described in more detail below. present description. More particularly, the arms 26, 28 are flexible transversely so that, when the base 22 is lowered onto the master cylinder 14, the arms 26, 28 move apart when passing transverse lugs 40 of the master cylinder forming the second locking means, as shown in FIG. 4, then retract when transverse bores 34 arranged near the ends of the arms and forming the first locking means receive the transverse lugs 40, as shown in FIG. 5. The lugs 40 advantageously extend transversely from the cylindrical barrel of the master cylinder 14. Advantageously, to facilitate the introduction of the pins
40 transversaux dans les perçages 34 transversaux, les bras 26, 28 comportent des gouttières 42 de guidage des ergots 40 qui sont formées dans des faces verticales intérieures 44 des bras 26, 28 entre leurs extrémités 36 et les perçages transversaux 34 et qui sont destinées à coopérer avec des chanfreins supérieurs40 transverse in the transverse bores 34, the arms 26, 28 comprise gutters 42 for guiding the pins 40 which are formed in internal vertical faces 44 of the arms 26, 28 between their ends 36 and the transverse bores 34 and which are intended for cooperate with upper chamfers
41 desdits ergots 40 pour faciliter l'écartement des bras 26, 28. Comme on l'a vu précédemment, les bras 26, 28 sont réalisés en un matériau sensiblement élastique en flexion pour permettre leur écartement. Tout matériau possédant de telles propriétés peut être utilisé pour la bonne réalisation de l'invention. Toutefois, dans le mode de réalisation préféré de l'invention , les bras 26, 28 sont réalisés en un matériau plastique. Par ailleurs, conformément à l'invention , l'embase 22 comporte des moyens 48 de préhension pour le montage de l'embase 22 sur le maître-cylindre 14. Ces moyens de préhension pourraient être destinés à la prise manuelle de l'embase 22 par un opérateur. Toutefois, dans le mode de réalisation préféré de l'invention , ces moyens 48 sont prévus pour la préhension de l'embase 22 à des fins de montage automatisé. A cet effet, les bords longitudinaux opposés 30 , 32 de l'embase sont conformés en queue d'aronde pour permettre leur préhension par deux bras 50 conformes d'un robot de montage automatisé. Chaque bord comporte une empreinte 48, les deux empreintes 48 formant la queue d'aronde. Ces bras 50, dont les extrémités 52 sont destinées à coopérer avec les empreintes 48 de queue d'aronde, ont été représentés aux figures 2 à 6. Dans cette configuration, un procédé de montage d'une embase 22 de réservoir sur un maître-cylindre 14 tels que précédemment décrits comporte une première étape au cours de laquelle les deux bras 50 d'un robot de montage sont agencés chacun en regard d'un bord 30, 32 de la queue d'aronde 48 de l'embase 22, comme représenté à la figure 2. Au cours de cette étape, les bras 50 peuvent par exemple assurer la préhension de l'embase 22 dans un magasin de stockage des embases 22. Puis le procédé comporte une deuxième étape au cours de laquelle les bras 50 sont serrés sur l'embase 22 de manière que l'extrémité de chacun des bras 50 pénètre dans l'empreinte 48 d u bord 30, 32 correspondant de l'embase 22. Dans cette configuration, les bras 50 maintiennent l'embase 22 d'une manière sensiblement analogue à celle qui a été représentée à la figure 3. A l'issue de cette deuxième étape, les bras 50 peuvent être déplacés pour déplacer l'embase selon une troisième étape dans une position, représentée à la figure 3, selon laquelle les bras 50 positionnent l'embase 22 au dessus du maître-cylindre 14, la pipe 16 d'alimentation étant agencée en regard du perçage 18 d'alimentation du maître-cylindre 14. Puis le procédé comporte une quatrième étape, représentée aux figures 4 et 5, au cours de laquelle les bras 26, 28 descendent l'embase 22 sur le maître-cylindre jusqu'à une position d'encliquetage des moyens 34, 40 d'immobilisation verticale, comme représenté plus particulièrement à la figure 5. Enfin le procédé comporte une cinquième et dernière étape au cours de laquelle les bras 50 sont écartés de l'embase 14, leurs extrémités 52 sortant des empreintes 48 et libérant ainsi le maître-cylindre 14 muni de son embase 22. 41 of said pins 40 to facilitate the spacing of the arms 26, 28. As we have seen previously, the arms 26, 28 are made of a material which is substantially elastic in bending to allow their spacing. Any material with such properties can be used for the proper realization of the invention. However, in the preferred embodiment of the invention, the arms 26, 28 are made of a plastic material. Furthermore, in accordance with the invention, the base 22 comprises gripping means 48 for mounting the base 22 on the master cylinder 14. These gripping means could be intended for manual engagement of the base 22 by an operator. However, in the preferred embodiment of the invention, these means 48 are provided for gripping the base 22 for the purpose of automated mounting. For this purpose, the opposite longitudinal edges 30, 32 of the base are shaped like a dovetail to allow their gripping by two arms 50 conforming to an automated assembly robot. Each edge has an imprint 48, the two imprints 48 forming the dovetail. These arms 50, the ends 52 of which are intended to cooperate with the dovetail imprints 48, have been shown in FIGS. 2 to 6. In this configuration, a method of mounting a base 22 of the reservoir on a master- cylinder 14 as previously described comprises a first step during which the two arms 50 of an assembly robot are each arranged opposite an edge 30, 32 of the dovetail 48 of the base 22, as shown in Figure 2. During this step, the arms 50 can for example ensure the gripping of the base 22 in a base storage store 22. Then the method comprises a second step during which the arms 50 are clamped on the base 22 so that the end of each of the arms 50 penetrates into the cavity 48 of the corresponding edge 30, 32 of the base 22. In this configuration, the arms 50 hold the base 22 of a substantially analogous to that which was tee shown in Figure 3. At the end of this second step, the arms 50 can be moved to move the base in a third step in a position, shown in FIG. 3, according to which the arms 50 position the base 22 above the master cylinder 14, the supply pipe 16 being arranged opposite the drilling 18 supplying the master cylinder 14. Then the method comprises a fourth step, shown in FIGS. 4 and 5, during which the arms 26, 28 descend the base 22 on the master cylinder to a latching position of the immobilizing means 34, 40 vertical, as shown more particularly in FIG. 5. Finally, the method comprises a fifth and final step during which the arms 50 are spaced from the base 14, their ends 52 leaving the imprints 48 and thus releasing the master cylinder 14 fitted with its base 22.
