[1] The invention relates to a set of two concentric parts fitted into each other of a mobility device. The invention also relates to a damping flywheel comprising such an assembly. Finally, the invention relates to a method of assembling two concentric parts of a mobility device. The mobility device can be a vehicle, in particular a motor vehicle.

Arrière-plan technologique Technological background
[2] [Fig. 1] est illustré un double volant amortisseur 1 comprenant une masse primaire 2 et une masse secondaire 3 entre lesquels est interposé un organe élastique (non illustré). La masse secondaire 3 comporte un plateau 4, un moyeu 5, un anneau de liaison 6 et un disque 7. Le disque 7 sert de support pour un dispositif pendulaire 9. Le plateau 4 forme un appui pour l’organe élastique. Le moyeu 5 forme une collerette 8 s’étendant radialement et formant un support de liaison avec le plateau 4 et le disque 7, le plateau 4 et le disque 7 étant liés au moyeu 5 de part et d’autre de la collerette 8. [2] [Fig. 1] is illustrated a double damping flywheel 1 comprising a primary mass 2 and a secondary mass 3 between which is interposed an elastic member (not illustrated). The secondary mass 3 comprises a plate 4, a hub 5, a connecting ring 6 and a disc 7. The disc 7 serves as a support for a pendulum device 9. The plate 4 forms a support for the elastic member. The hub 5 forms a collar 8 extending radially and forming a connection support with the plate 4 and the disc 7, the plate 4 and the disc 7 being connected to the hub 5 on either side of the collar 8.
[3] [Fig. 2] et [Fig. 3] est illustré l’assemblage d’une partie de la masse secondaire 3. L’anneau de liaison 6 est d’abord posé sur une première face 10 de la collerette 8. Puis le disque 7 est positionné sur l’anneau de liaison 6 et lié en rotation au moyeu 5 par rivetage du disque 7, de l’anneau de liaison 6 avec la collerette 8. [3] [Fig. 2] and [Fig. 3] is illustrated the assembly of part of the secondary mass 3. The connecting ring 6 is first placed on a first face 10 of the flange 8. Then the disc 7 is positioned on the connecting ring 6 and connected in rotation to the hub 5 by riveting the disc 7, the connecting ring 6 with the collar 8.
[4] Ainsi, l’assemblage du moyeu 5, de l’anneau de liaison 6 et du disque 7 nécessite un certain nombre d’opérations qui rendent le procédé d’assemblage complexe et coûteux. [4] Thus, the assembly of the hub 5, the link ring 6 and the disc 7 requires a number of operations which make the assembly process complex and expensive.
Résumé summary
[5] Une idée à la base de l’invention consiste à proposer un ensemble de deux pièces concentriques emmanchées l’une dans l’autre visant à résoudre les problèmes précités. [5] An idea underlying the invention is to provide a set of two concentric pieces fitted into each other aimed at solving the aforementioned problems.
[6] Pour ce faire, l’invention propose un ensemble de deux pièces concentriques emmanchées l'une dans l'autre, dont l'une centrale est cylindrique et dont l'autre est en forme de disque avec une ouverture centrale dentelée pour solidariser angulairement les deux pièces l'une avec l'autre après emmanchement de l’une sur l’autre, le disque étant bloqué axialement sur la pièce centrale par une première butée formée par la pièce centrale et par une deuxième butée formée après soudage avec apport de matière. [6] To do this, the invention provides a set of two concentric pieces fitted into one another, the central one of which is cylindrical. and the other of which is in the form of a disc with a serrated central opening for angularly securing the two parts to one another after fitting one onto the other, the disc being axially locked on the central part by a first stop formed by the central part and by a second stop formed after welding with addition of material.
[7] Grâce à l’invention, l’assemblage est réalisé plus simplement et nécessite que très peu d’étapes. L’assemblage est également réalisé de telle manière à bloquer axialement en position le disque selon deux directions opposées. [7] Thanks to the invention, the assembly is carried out more simply and requires very few steps. The assembly is also carried out in such a way as to axially block the disc in position in two opposite directions.
[8] Selon d’autres modes de réalisation de l’invention, l’ensemble peut comporter une ou plusieurs des caractéristiques décrites ci-dessous : le soudage est réalisé par une technologie par soudage telle que MIG (Métal Inert Gas), TIG (Tungsten Inert Gas), MAG (Métal Active Gas), CMT (Cold Métal Transfer) ou laser. la pièce centrale forme une collerette s’étendant radialement et formant la première butée. le disque présente un pourtour interne avec un premier diamètre compris entre un deuxième diamètre délimité par un pourtour externe de la pièce centrale et un deuxième diamètre délimité par un sommet de la collerette. [8] According to other embodiments of the invention, the assembly may include one or more of the characteristics described below: the welding is carried out by welding technology such as MIG (Metal Inert Gas), TIG ( Tungsten Inert Gas), MAG (Metal Active Gas), CMT (Cold Metal Transfer) or laser. the central piece forms a flange extending radially and forming the first stop. the disc has an internal periphery with a first diameter between a second diameter delimited by an external periphery of the central part and a second diameter delimited by a top of the collar.
[9] L’invention a aussi pour objet un procédé d'assemblage de deux pièces concentriques emmanchées l'une dans l'autre, dont l'une est cylindrique et dont l'autre est en forme de disque avec une ouverture centrale dentelée ayant des dents qui, lors de l'emmanchement sur celle-ci, permettent de solidariser angulairement les deux pièces l'une avec l'autre, dans lequel il comporte les étapes suivantes : bloquer axialement le disque sur la pièce centrale selon une première direction par appui sur une première butée formée par la pièce centrale bloquer axialement le disque sur la pièce centrale selon une deuxième direction par une deuxième butée formée après soudage par apport de matière, emmanchement des deux pièces l’une dans l’autre jusqu’à appui des deux pièces l’une contre l’autre, et soudage par apport de matière des deux pièces entre elles. [9] The invention also relates to a method of assembling two concentric pieces fitted into one another, one of which is cylindrical and the other of which is disc-shaped with a serrated central opening having teeth which, when fitting onto the latter, allow the two parts to be angularly secured to one another, in which it comprises the following steps: axially locking the disc on the central part in a first direction by bearing on a first stop formed by the central part axially block the disc on the central part in a second direction by a second stop formed after welding by addition of material, fitting of the two parts one inside the other until the support of the two parts against each other, and welding by addition of material of the two parts between them.
[10] Selon un mode de réalisation, le procédé comporte également l’étape suivante : souder le disque et la pièce centrale par la technologie par soudage telle que MIG (Métal Inert Gas), TIG (Tungsten Inert Gas), MAG (Métal Active Gas), CMT (Cold Métal Transfer) ou laser.

[23] La [Fig. 4] illustre un moyeu 10 et un disque 11 avant assemblage selon un premier exemple de réalisation de l'invention. La [Fig. 5] illustre le moyeu 10 et le disque 11 assemblés selon le premier exemple de l’invention. Le moyeu 10 et le disque 11 peuvent faire partie d’un double volant amortisseur d’un véhicule automobile (non illustrés). Le disque 11 peut faire partie d’une masse secondaire (non représentée) d’un tel double volant amortisseur et servir de support à un dispositif pendulaire (non représenté). Le moyeu 10 et le disque 11 forment deux pièces concentriques. [23] [Fig. 4] illustrates a hub 10 and a disc 11 before assembly according to a first exemplary embodiment of the invention. The [Fig. 5] illustrates the hub 10 and the disc 11 assembled according to the first example of the invention. The hub 10 and the disc 11 may form part of a double damping flywheel of a motor vehicle (not shown). The disc 11 can form part of a secondary mass (not shown) of such a double damping flywheel and serve as a support for a pendulum device (not shown). The hub 10 and the disc 11 form two concentric parts.
[24] Le moyeu 10 présente une partie allongée cylindrique 12 et une collerette 13 s’étendant radialement à partir de la partie cylindrique 12. La partie cylindrique 12 présente sur un pourtour interne une surface cannelée 14 apte à s’engrener avec une surface correspondante formée par un arbre, dans un exemple un arbre de transmission de boîte de vitesses. Le pourtour externe 15 de la partie cylindrique 12 présente une surface lisse. [24] The hub 10 has an elongated cylindrical part 12 and a flange 13 extending radially from the cylindrical part 12. The cylindrical part 12 has on an internal periphery a grooved surface 14 adapted to mesh with a corresponding surface formed by a shaft, in one example a gearbox transmission shaft. The outer periphery 15 of the cylindrical part 12 has a smooth surface.
[25] Le disque 11 présente dans cet exemple une forme de pot avec un orifice central 16 bordé d’un bord périphérique dentelé 17. Le bord périphérique dentelé 17 présente un diamètre compris entre celui délimité par le pourtour externe 15 de la partie cylindrique 12 du moyeu 10 et celui délimité par un sommet 18 de la collerette 13. [25] The disc 11 has in this example the shape of a pot with a central orifice 16 bordered by a serrated peripheral edge 17. The serrated peripheral edge 17 has a diameter between that delimited by the periphery external 15 of the cylindrical part 12 of the hub 10 and that delimited by a top 18 of the collar 13.
[26] Les dents formées par le bord périphérique 17 sont réalisées avec une dureté plus importante que celle formée par le pourtour externe 15. Ainsi, au moment de l’assemblage du moyeu 10 et du disque 11 l’un avec l’autre, les dents vont s’incruster dans la matière formée par le moyeu 10 assurant ainsi la solidarisation en rotation du moyeu 10 et du disque 11 l’un avec l’autre. [26] The teeth formed by the peripheral edge 17 are produced with a greater hardness than that formed by the outer periphery 15. Thus, when the hub 10 and the disc 11 are assembled with each other, the teeth will become embedded in the material formed by the hub 10 thus ensuring the rotational connection of the hub 10 and the disc 11 to one another.
[27] Le disque 11 est placé autour du moyeu 10 tout en étant retenu axialement par appui contre la collerette 18 selon une première direction. Une fois le moyeu 10 et le disque 11 assemblés, le disque 11 est également retenu axialement selon une deuxième direction, opposée à la première direction. Cette retenue axiale s’effectue par l’intermédiaire d’un point de soudure 19. Ce point de soudure 19 est réalisé par l’intermédiaire de technologies du type MIG (Métal Inert Gas), MAG (Métal Active Gas), TIG (Tungsten Inert[27] The disc 11 is placed around the hub 10 while being retained axially by resting against the collar 18 in a first direction. Once the hub 10 and the disc 11 are assembled, the disc 11 is also retained axially in a second direction, opposite to the first direction. This axial retention is effected by means of a weld point 19. This weld point 19 is produced by means of technologies of the MIG (Metal Inert Gas), MAG (Metal Active Gas), TIG (Tungsten) type. Inert
Gas), CMT (Cold Métal Transfer) ou par laser. Gas), CMT (Cold Metal Transfer) or by laser.
[28] Les [Fig. 6] et [Fig. 7] illustrent l’assemblage d’un moyeu 10a et d’un disque 11a selon un autre exemple de l’invention. Le moyeu 10a et le disque 11a sont assemblés l’un avec l’autre jusqu’à ce que le disque 11a vienne en butée contre la collerette 13a [Fig. 6], [Fig. 7] Le disque 11a présente au niveau de son bord périphérique interne, bordant le pourtour périphérique interne dentelé 17a, une face première face axiale 20a. Ainsi, le disque 11 a vient en appui par sa première face d’appui 20a contre une surface correspondante formée par la collerette 13a. Puis, un point de soudure 19a est appliqué entre le disque 11a et le moyeu 10a comme illustré en 19a[28] The [Fig. 6] and [Fig. 7] illustrate the assembly of a hub 10a and a disc 11a according to another example of the invention. The hub 10a and the disc 11a are assembled with each other until the disc 11a abuts against the flange 13a [Fig. 6], [Fig. 7] The disc 11a has, at its internal peripheral edge, bordering the indented internal peripheral periphery 17a, a first axial face 20a. Thus, the disc 11a comes to bear by its first bearing face 20a against a corresponding surface formed by the collar 13a. Then, a weld point 19a is applied between the disc 11a and the hub 10a as illustrated at 19a
[Fig. 7] Comme pour l’exemple précédent, ce point de soudure 19a est réalisé par l’intermédiaire de technologies du type MIG (Métal Inert Gas), MAG (Métal Active Gas), TIG (Tungsten Inert Gas), CMT (Cold Métal Transfer) ou par laser. Ce point de soudure 19a est réalisée sur une deuxième face axiale 21 a, opposée à la face axiale 20a.j [Fig. 7] As for the previous example, this weld point 19a is produced by means of technologies of the MIG (Metal Inert Gas), MAG (Metal Active Gas), TIG (Tungsten Inert Gas), CMT (Cold Metal Transfer) type. ) or by laser. This weld point 19a is made on a second axial face 21a, opposite to the axial face 20a.j
