The secondary mass 3 has a plate 4, a hub 5, a connecting ring 6 and a disc 7. The disc 7 serves as a support for the pendulum device 9. The plate 4 forms a support for the elastic member. The hub 5 forms a radially extending collar 8, the collar 8 together with the plate 4 and the disc 7 forming a connection support, the plate 4 and the disc 7 being connected to the hub 5 on both sides of the collar 8.

The disk has an inner periphery of a first diameter comprised between a second diameter defined by the outer periphery of the central member and a second diameter defined by the apex of the collar.
The utility model also relates to a method for assembling two concentric parts, one of which is push-fit into the other part, one of which is cylindrical and the other part is in the form of a disc with a toothed central opening having teeth which allow the two parts to be fixed angularly to each other when a push-fit is performed thereon, wherein the method comprises the steps of:
by bearing against a first stop formed by the central member, axially locking the disc to the central member in a first direction,
by means of a second stop formed after welding of the additive material, the disc is axially locked to the central part in a second direction,
press-fit one of the two parts into the other until the two parts bear against each other, and
the two parts are welded together by adding material.
According to one embodiment, the method further comprises the steps of:
welding techniques such as MIG (metal inert gas), TIG (tungsten inert gas), MAG (metal active gas), CMT (cold metal transfer) or by laser welding of the disc and the central part are used.
Finally, the utility model relates to a dual mass flywheel, characterized in that it has two concentric parts forming an assembly according to the above, the two concentric parts being assembled by a method according to the above, the central part constituting a hub of the dual mass flywheel, the hub being able to interact with a shaft, while the other part constitutes a plate of the dual mass flywheel forming a support for an elastic member, or constitutes a plate establishing additional inertia, or constitutes a support for a pendulum device.

Detailed Description
Unless otherwise indicated, "axial" means "parallel to the rotational axis X" of the device; "radial" means "along a transverse axis intersecting the axis of rotation of the device"; "angularly" or "circumferentially" means "about the axis of rotation of the device";
"front" or "rear" in the direction defined with respect to the axial orientation determined by the rotational axis X of the torque transmitting device, the "front" representing the portion located to the right in the figure, for example on one side of the gearbox, and the "rear" representing the portion to the left in the figure, for example on one side of the engine; and
"inner/inner" or "outer/outer" is with respect to the rotation axis X and in a radial orientation orthogonal to the axial direction, "inner" means a portion close to the rotation axis X, and "outer" means a portion distant from said rotation axis X.
Fig. 4 shows the hub 10 and the disc 11 before assembly according to the first exemplary embodiment of the present utility model. Fig. 5 shows a hub 10 and a disc 11 assembled according to a first example of the utility model. The hub 10 and the disc 11 may be part of a dual mass flywheel of a motor vehicle (neither shown). The disc 11 may be part of a secondary mass (not shown) of such a dual mass flywheel and serves as a support for a pendulum device (not shown). Hub 10 and disk 11 form two concentric parts.
Hub 10 has an elongated cylindrical portion 12 and a collar 13 extending radially from cylindrical portion 12. On the inner periphery, the cylindrical portion 12 has a splined surface 14, the splined surface 14 being capable of engaging with a corresponding surface formed by a shaft, which in one example is a gearbox drive shaft. The outer periphery 15 of the cylindrical portion 12 has a smooth surface.
In this example, the disc 11 has the form of a can having a central aperture 16, the central aperture 16 being defined by a toothed peripheral edge 17. The diameter of the toothed peripheral edge 17 is between the diameter defined by the outer periphery 15 of the cylindrical portion 12 of the hub 10 and the diameter defined by the apex 18 of the collar 13.
The teeth formed by the peripheral edge 17 have a hardness greater than that of the peripheral edge 15. Thus, when the hub 10 and the disc 11 are assembled to each other, the teeth will be embedded in the material formed by the hub 10, thereby ensuring that the hub 10 and the disc 11 are fixed for co-rotation with each other.
The disc 11 is placed around the hub 10 while still being axially held by abutment against the collar 18 in the first direction. Once the hub 10 and the disc 11 have been assembled, the disc 11 is also axially retained in a second direction opposite to the first direction. This axial retention is achieved by spot welds 19. The spot welds 19 are made using MIG (metal inert gas), MAG (metal active gas), TIG (tungsten inert gas), CMT (cold metal transfer) type techniques or by laser.
Fig. 6 and 7 show the assembly of a hub 10a and a disc 11a according to another example of the utility model. The hub 10a and the disc 11a are assembled with each other until the disc 11a abuts against the collar 13a [ fig. 6], [ fig. 7]. The disk 11a has a first face axial face 20a at its inner peripheral edge, which first face axial face 20a abuts the toothed inner Zhou Zhouyuan a. Thus, the disc 11a is supported by its first bearing surface 20a against the corresponding surface formed by the collar 13 a. Spot welds 19a are then applied between the disc 11a and the hub 10a as shown at 19a [ fig. 7]. Similar to the previous example, the spot welds 19a are made using MIG (metal inert gas), MAG (metal active gas), TIG (tungsten inert gas), CMT (cold metal transfer) type techniques or by laser. The spot welds 19a are formed on a second axial surface 21a opposite the axial surface 20 a.
