- the invention also relates to a damping flywheel of such a mobility device.
- 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.
- FIG. 2 [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.
- An idea underlying the invention is to provide a set of two concentric pieces fitted into each other aimed at solving the aforementioned problems.
- 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.
- 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.
- 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.
- 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.
- the method also comprises the following step: weld the disc and the central part by welding technology such as MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), MAG (Metal Active Gas), CMT (Cold Metal Transfer) or laser.
- MIG Metal Inert Gas
- TIG Transmissionsten Inert Gas
- MAG Metal Active Gas
- CMT Cold Metal Transfer
- the invention finally relates to a double damping flywheel, characterized in that it comprises two concentric parts forming an assembly according to one of claims 1 to 4 assembled by the method according to claim 5, the central part constituting a hub of the double flywheel able to cooperate with a shaft while the other part constitutes a plate of the double flywheel forming a support for an elastic member, or else a plate forming an additional inertia, or else a support for a pendulum device.
- FIG. 1 illustrates a sectional view of a double damping flywheel according to the prior art
- FIG. 2 illustrates an exploded perspective view of part of the double damping flywheel according to [Fig. 1]; [15] [Fig. 3] illustrates an assembled perspective view of the part according to
- FIG. 4 illustrates an exploded perspective view of part of a set of two concentric pieces according to one embodiment of the invention
- [17] illustrates a view of the part illustrated in [Fig. 4] in assembled condition
- FIG. 6 illustrates a step of the method of assembling a set of two concentric parts according to another embodiment of the invention
- [Fig. 7] illustrates another step of the method of assembling an assembly of two concentric parts according to another embodiment of the invention
- axially means “parallel to an axis of rotation X of the device”
- “Radially” means “along a transverse axis intersecting the axis of rotation of the device”
- Angularly” or “circumferentially” means “around the axis of rotation of the device”.
- 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.
- 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.
- 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.
- 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.
- 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
- 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.
- the disc 11a comes to bear by its first bearing face 20a against a corresponding surface formed by the collar 13a.
- a weld point 19a is applied between the disc 11a and the hub 10a as illustrated at 19a
- 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
