La partie 6, filetée, forme une vis 14 permettant d'assurer la liaison entre l'élément de suspension et le support 5 par l'intermédiaire d'un écrou ou de tout autre partie taraudée. Part 6, threaded, forms a screw 14 for ensuring the connection between the suspension element and the support 5 by means of a nut or any other threaded portion.
La partie 7 est intégrée au support. Cette partie 7 comporte un corps 10 muni à son extrémité d'une tête 9. Cette tête 9 comporte au moins un méplat 11. Sur la figure 1, le goujon 4 comporte six méplats 11. Le plan passant par chaque méplat 11 est parallèle à l'axe D. Ces méplats 11 permettent de bloquer le goujon 4 en rotation autour de l'axe D. Le corps 10 comporte au moins une rainure 12 et au moins deux bossages 15 de part et d'autre de chaque rainure 12. Sur la figure 2, le goujon 4 comporte trois rainures 12 et quatre bossages 15. Les rainures 12 et les bossages 15 sont perpendiculaires à l'axe D. Ces rainures 12 et ces bossages 15 ont un rôle de blocage en translation selon l'axe D. De cette façon, le goujon 4 est maintenu et peut subir les sollicitations du ris GMP. Part 7 is integrated into the support. This part 7 comprises a body 10 provided at its end with a head 9. This head 9 comprises at least one flattened portion 11. In FIG. 1, the stud 4 comprises six flats 11. The plane passing through each flat 11 is parallel to the axis D.

Le procédé de fabrication d'un support 5 comportant un 20 goujon 4 comporte les étapes suivantes: - le goujon 4 est positionné et maintenu dans un moule de support 5, - la matière du support 5 est coulée dans le moule. The method of manufacturing a support 5 having a stud 4 comprises the following steps: - the stud 4 is positioned and held in a support mold 5, the material of the support 5 is cast in the mold.
L'écoulement de la matière du support 5 autour du goujon 4 est facilité grâce à la forme des rainures 12 et des bossages 15. Les rainures 12 sont creuses et les bossages 15 sont de forme de partie de tore. Ainsi, la matière peut être répartie de façon homogène et la matière ne comporte pas ou très peu de bulles d'air autour du goujon 4. De cette façon, la fragilisation du support 5 est considérablement 3réduite. The flow of the material of the support 5 around the stud 4 is facilitated by the shape of the grooves 12 and the bosses 15. The grooves 12 are hollow and the bosses 15 are torus-shaped portion. Thus, the material can be homogeneously distributed and the material has little or no air bubbles around the stud 4. In this way, the embrittlement of the support 5 is considerably reduced.
La matière du support 5 est choisie de façon à ce que son point de fusion est inférieur à celui de la matière du goujon 4. Le goujon 4 peut être en acier et le support 5 en aluminium. The material of the support 5 is chosen so that its melting point is less than that of the material of the stud 4. The stud 4 can be made of steel and the support 5 is made of aluminum.
L'association du goujon 4 au support 5 permet de minimiser les coûts. Le nombre des étapes pour monter le tampon est réduit puisqu'il n'est plus nécessaire de monter le goujon 4 dans le support 5. En effet, lors de l'étape de fabrication du support 5, l'insertion du goujon 4 est également réalisée. The association of the stud 4 to the support 5 makes it possible to minimize the costs. The number of steps for mounting the buffer is reduced since it is no longer necessary to mount the pin 4 in the support 5. Indeed, during the step of manufacturing the support 5, the insertion of the stud 4 is also performed.
Ce goujon 4 n'est pas limité au support de boîte de vitesse. Il o peut être intégré dans tout type de support 5. 20 This stud 4 is not limited to the gearbox support. It can be integrated in any type of support 5. 20
