    Support for pendular damping device and pendular damping device comprising such a support
    The present invention relates to a pendular damping device, in particular for a motor vehicle transmission system.
    In such an application, the pendulum damping device can be integrated with a torsion damping system of a clutch capable of selectively connecting the heat engine to the gearbox, in order to filter the vibrations due to the acyclisms of the engine. Such a torsion damping system is for example a double damping flywheel.
    Alternatively, in such an application, the pendulum damping device may be integrated with a friction disc of the clutch or a hydrodynamic torque converter or a flywheel secured to the crankshaft or a double clutch dry or wet.
    Such a pendular damping device conventionally implements a support and one or more pendular bodies movable relative to this support, the displacement relative to the support of each pendulum body being guided by two rolling members cooperating on the one hand with bearing tracks secured to the support, and secondly with rolling tracks secured to the pendulum body.
    The support of the pendular damping device must generally: on the one hand ensure the physical connection of the pendular damping device to the rest of the transmission system, and on the other hand be sufficiently robust to guide the displacement of the pendular bodies while by resisting the shocks exerted on him in operation by these pendular bodies.
    It is known, in response to this double constraint, to use a support in two distinct parts, one of these parts of the support being specific to the physical connection to the rest of the transmission system, and the other of these parts of the support being specific for guiding the displacement of the pendular bodies. Such a support is nevertheless expensive to produce.
    There is a need to take into account the double constraint mentioned above in a simple and inexpensive way. The aim of the invention is to meet this need and it achieves this, according to one of its aspects, with the aid of a support for pendular damping device, comprising: a first part able to be connected to a component of a motor vehicle transmission system, and - a second part in which is provided at least a first raceway adapted to cooperate with a rolling member to guide the displacement of a pendulum body, the first part and the second part being rigidly interconnected and the first part being obtained by cutting the central zone of the second part.
    According to the invention, the first part and the second part of the support are made from a single piece, for example a steel sheet. As a result, it is not necessary to use two separate starting pieces to carry out the support. The falls of the second part then form the first part of the support.
    The two-part separation of the starting piece makes it possible to adapt each part of the support to the stress that this part must allow to hold, before rigid coupling between these two parts. For example, the second part, after cutting, is subjected to a hardening treatment in order to increase its robustness. This treatment is for example a heat treatment allowing a contribution of carbon to harden the second part of the support. The carbon input is done for example by carbonitriding or nitriding. This hardening treatment then does not affect the first part of the support which has been separated from the second part of the support, which is all the more advantageous as such a heat treatment may make it more difficult for a solder connection of the first part of the support. part of the support to the rest of the transmission system.
    Alternatively or additionally, a coating for attenuating the vibrations of the support during an impact exerted by the mass on this support can be deposited on the second part of the support, once the first portion cut. The coating may be Deltaflon ™ sold by the company Fluorotechnique (R). This coating can be applied to the support by projection, electrolysis or vapor phase. Such a coating implements PTFE.
    When cutting the first part, the first race or tracks may have already been formed in the second part of the support.
    Alternatively, when cutting the first part, the first race or tracks have not yet been formed in the second part of the support.
    For the purposes of the present application: - "axially" means "parallel to the axis of rotation of the support", - "radially" means "along an axis belonging to a plane orthogonal to the axis of rotation of the support and intersecting this axis of rotation of the support ", -" angularly "or" circumferentially "means" around the axis of rotation of the support ", -" orthoradially "means" perpendicular to a radial direction ", -" integral "means" rigidly coupled ", and - the rest position of a pendulum body is that in which the pendulum body is centrifuged without being subjected to torsional oscillations from the acyclisms of the engine.
    The first part of the support may have on its radially outer periphery an alternation of solid portions and empty portions, the second part of the support having on its radially inner periphery an alternation of solid portions and empty portions. When moving along a given diameter, it is thus possible, on the one hand, to encounter an alternation of solid portions and empty portions of the first part of the support, and on the other hand an alternation of solid portions and portions. empty of the second part of the support.
    Each solid portion, respectively empty, of the first part of the support may have a shape complementary to that of an empty portion, respectively full, of the second part of the support. This complementarity of shape can result from the cutting of the first part in the second part of the support.
    Each solid portion of the first portion of the support has, for example, in a plane orthogonal to the axis of rotation, a petal shape. The set of solid portions of the first part of the support here forms the radially outer zone of the first part of the support. Each solid portion of the first portion of the support extends for example radially outwardly from a ring forming the radially inner zone of the first part of the support. The connection of the support to the rest of the transmission system can be done via this radially inner zone of the first part of the support.
    The first part of the support can be axially offset with respect to the second part of the support. The first part of the support can mainly extend radially inside the second part of the support.
    Each solid portion, respectively empty, of the first portion of the support may be axially facing all or part of a solid portion, respectively empty, of the second part of the support. In other words, when one rigidly connects the first part and the second part of the support, for example once the treatment or treatments mentioned above, the first and second part is positioned so that the portions full of the first part of the support are axially facing full portions of the second part of the support.
    The rigid connection between the first and the second part of the support can implement coupling members, each coupling member being received in an area of a solid portion of the first portion of the support and in a zone of a solid portion. of the second part of the support which are axially opposite. These coupling members may be axially extending rivets. Each solid portion of the first portion of the support can be rigidly connected to a solid portion of the second portion of the support via at least one coupling member, in particular at least one rivet.
    Alternatively, the rigid connection between the first portion and the second portion of the support implements a press fit. The solid portions of the first portion of the support may have different dimensions relative to each other. Thus, a solid portion of the first part of the support of a first type has, for example, a small radially inner dimension and a high radially external dimension while a solid portion of the first part of the second type of support has a dimension radially inward elevation and a small radially outer dimension. The rigid connection is then effected by forcing in force: the solid portions of the first part of the support of the first type in empty portions of the second part of the support resulting from the cutting of the full portions of the first part of the support of the second type and the solid portions of the first part of the support of the second type in empty portions of the second part of the support resulting from the cutting of solid portions of the first part of the support of the first type. The force fit is thus done for each solid portion of the first part of the support of the first type at its radially outer dimension while the force fit is made for each solid portion of the first part of the support of the second type. at its radially inner dimension. The invention further relates, in another of its aspects, to a pendular damping device, comprising: a support as defined above, and at least one movable pendular body with respect to the support, the displacement relative to the support of the pendular body being guided by at least one rolling member cooperating on the one hand with the first raceway and on the other hand with at least one second raceway secured to the pendulum body.
    The displacement of the pendular body relative to the support can be guided by two rolling members in which case the damping device is called "two-wire".
    Each rolling member cooperates for example with at least one first running track secured to the support and with at least one second running track integral with the pendulum body. Each rolling member cooperates for example with the running track (s) integral with the support and with the running track (s) integral with the pendular body only via its outer surface.
    Each rolling member is for example a roll of circular section in a plane perpendicular to the axis of rotation of the support. This roll may comprise several successive cylindrical portions of different radius. The axial ends of the roll may be devoid of a thin annular flange. The roller is for example made of steel. The roll may be hollow or full.
    In all the foregoing, the device comprises for example a number of pendulum bodies between two and eight, including three, four, five or six pendulous bodies. All these pendular bodies may succeed one another circumferentially. The device may thus comprise a plurality of planes perpendicular to the axis of rotation in each of which all the pendular bodies are arranged.
    In all that precedes the shape of the aforementioned first and second runways may be such that each pendular body is only displaced relative to the support in translation about a fictitious axis parallel to the axis of rotation of the support.
    As a variant, the shape of the rolling tracks may be such that each pendular body is displaced with respect to the support both: in translation about a fictitious axis parallel to the axis of rotation of the support and also in rotation around the center of gravity of said pendulum mass, such a movement being again called "combined movement" and disclosed for example in the application DE 10 2011 086 532.
    According to an exemplary implementation of the invention, the pendulum body may comprise a first pendular mass axially disposed on a first side of the second part of the support and a second pendular mass axially arranged on a second side of the second part. the support, the first and the second pendulum mass being secured to each other by at least one connecting member.
    According to this exemplary implementation of the invention, the pendulum damping device may comprise a noise attenuation system occurring during an impact of the pendular body on the support, this attenuation system being disposed axially from each side of the second part of the support and axially tightening the latter.
    The attenuation system can make it possible to take into account the undesirable noise and / or vibration of the support occurring especially during the start-up or during the stopping of the engine of the vehicle. Starting and stopping the heat engine correspond to low speeds that can cause desynchronization of the pendular bodies relative to the support, so that these pendular bodies can drop radially and strike against the support. Such shock can then cause these vibrations and / or these undesirable noises.
    The noise attenuation system may comprise a first element axially disposed on a first side of the second part of the support and a second element axially disposed on a second side of this second part of the support.
    This first and second element may be separate parts secured to the support, for example to the second part of the support, in particular by attachment to areas of the second part of the support arranged radially beyond the solid portions of this second part. This attachment is made for example by screwing, riveting, ultrasonic welding, heat sealing ...
    Each element of the attenuation system may have on its radially inner periphery an alternation of full portions and empty portions. For example, there exists an empty portion of the first element of said system which is axially facing a solid portion of the second element of said system, while being axially facing an empty portion of the first part of the support and a portion empty of the second part of the support. These two elements of the attenuation system can be fixed together via these two solid portions through the empty axial space formed by the empty portions of the support.
    Alternatively, there may be zones of each element of the noise attenuation system which are axially facing a solid portion of the first portion of the support and a solid portion of the second portion of the support, and the attachment from the noise attenuation system to the support can be via screws or rivets received in these zones and these full portions. This fixation can still implement other means.
    In another variant, the first and the second element of the noise attenuation system may be a single piece overmolded on the second part of the support.
    The second part of the support may carry at least one axial interposition piece arranged axially facing the first pendulum mass or the second pendulum mass, this axial interposition piece being in particular a coating deposited on the support.
    Such an interposition piece can thus limit the axial displacement of the pendular mass relative to the support, thereby avoiding axial shocks between said parts, and thus wear and unwanted noises, especially when the support and / or the pendulum mass are made of metal.
    When the interposition piece is a coating, this coating is for example as mentioned above.
    Alternatively, the axial interposition piece may be a pad carried by the support. This pad may be plastic and be hooked on the support via one or more fasteners mounted in one or more holes of the support.
    The interposition pieces can be positioned on the support so that there is always at least one interposition piece of which at least part is axially interposed between a pendulum mass and the support, whatever the relative positions. support and said mass.
    According to this exemplary implementation, each pendulum body may comprise at least one abutment damping member, adapted to simultaneously come into contact with the pendulum body and the support in relative positions of the pendular body relative to the support. These relative positions are for example: the position at the end of a displacement in the counterclockwise direction of this pendulum body from the rest position to filter a torsion oscillation, and / or the position at the end of a displacement in the non-trigonometric direction of the pendulum body from the rest position for filtering a torsional oscillation, and / or - the position at the end of a radial fall of this pendulum body, in particular when starting or stopping the vehicle engine.
    Each abutment damping member may be dedicated to a connecting member of the pendular body and carried by the latter. Each abutment damping member may have elastic properties for damping shocks related to the contact between the support and the pendulum body. This damping is then allowed by a compression of the abutment damping member, the latter being for example elastomer or rubber.
    According to a first preferred embodiment, the rolling member cooperates with a single first raceway and with only one second raceway, and the second raceway is defined by the connecting member of the pendular body. A portion of the contour of this connecting member defines for example the second rolling track. Alternatively, a coating may be deposited on this portion of the contour of the connecting member to form the second raceway. Such a connecting member is for example force-fitted via each of its axial ends into an opening in one of the pendular masses. Alternatively, the connecting member may be welded or screwed or riveted via its axial ends on each pendulum mass.
    According to the first preferred embodiment, the displacement of each pendular body relative to the support can be guided by at least two rolling members, in particular exactly two rolling members. Two connecting members each cooperating with a rolling member may be provided.
    Each rolling member can then be stressed only in compression between the first and second raceways mentioned above. These first and second raceways cooperating with the same rolling member may be at least partly radially opposite, that is to say that there are plans perpendicular to the axis of rotation in which these tracks both extend.
    According to the first preferred embodiment, each rolling member can be received in a window of the support already receiving a connecting member and receiving no other rolling member. This window is for example defined by a closed contour, a portion of which defines the first rolling track secured to the support which cooperates with this rolling member.
    According to a second preferred embodiment, the rolling member cooperates on the one hand with a single first raceway secured to the support, and on the other hand with two second raceways integral with the pendulum body. Each pendulum mass then has an opening of which part of the contour defines one of these second raceways.
    According to this second preferred embodiment, each connecting member includes for example several rivets, and this connecting member is received in a window of the support, while the rolling member is received in an opening of the support, distinct from a window receiving a liaison member.
    According to this second preferred embodiment, two rolling members can guide the displacement of the pendular body relative to the support, and each rolling member cooperates with a first rolling track dedicated to this rolling member and with two second running tracks dedicated to this running gear.
    According to this second preferred embodiment, each rolling member can then comprise successively axially: a portion disposed in an opening of the first pendulum mass and cooperating with the second rolling track formed by a part of the contour of this opening, a portion disposed in an opening of the support and cooperating with the first raceway formed by a portion of the contour of this opening, and - a portion disposed in an opening of the second pendulum mass and cooperating with the second raceway formed by a portion of the contour of this opening.
    According to this first example of implementation, there is a single support guiding via its second part the displacement of the pendular bodies.
    According to a second example of implementation, the displacement of each pendulum body can be guided by two supports, each being as mentioned above. These two supports are then axially offset and integral. In this case, the pendulum body may comprise only a pendulum mass disposed axially between the two supports, or if necessary several pendular masses secured together and arranged axially between the two supports.
    According to this second example of implementation of the invention, each support may carry a noise attenuation system occurring during an impact of the pendular body on this support, this attenuation system being disposed axially on each side of the support and axially tightening the latter. In a variant, the noise attenuation system associated with each support is arranged axially only on the side of this support which is opposite the pendulum body. The invention further relates, in another of its aspects, to a component for transmission system of a motor vehicle, the component being in particular a double damping flywheel, a hydrodynamic torque converter, a flywheel integral with the crankshaft, or a clutch friction disc or a double clutch dry or wet, this component comprising a pendular damping device as defined above.
    The support of the pendular damping device may then be one of: - a web of the component, - a guide washer of the component, - a phasing washer of the component, or - a separate support of said web, said washer of guide and said phasing washer.
    In the case where the device is integrated with a flywheel secured to the crankshaft, the support can be integral with this flywheel.
    The component is in particular a clutch friction disc. In such a case, the support may be connected to the hub of the friction disc. The first part of the support is for example welded to this hub. The invention further relates, in another of its aspects, to a method of producing a support for pendular damping device, comprising the following steps: - cutting the central zone of a sheet to form a first part support member adapted to be connected to a vehicle transmission system component, the remainder of the sheet forming a second support portion having at least a first raceway adapted to cooperate with a rolling member to guide the movement of a pendular body, and - rigidly connect the first part and the second part.
    The method may include the step of subjecting the second portion, after the cutting step and before the rigid bonding step to the first portion, to a curing treatment, such as carbonitriding or nitriding.
    All or part of what has been mentioned in connection with the preceding aspect of the invention still applies to this other aspect. The invention will be better understood on reading the following description of a nonlimiting example of implementation thereof and on examining the appended drawing in which: FIG. part a transmission system component with a pendulum damping device, and - Figure 2 shows the component of Figure 1 when assembled
    FIG. 1 shows a transmission system component 1 comprising a pendular damping device 2 according to an exemplary implementation of the invention.
    This component 1 is here a clutch friction disc, only the hub 3 being shown here. This component 1 is for example associated with a thermal engine including two, three or four cylinders.
    The pendulum damping device 2 comprises in the example under consideration: a support 4 able to move in rotation about an axis X, and a plurality of pendular bodies movable relative to the support 4.
    In the example considered, three pendulous bodies 5 are provided, being uniformly distributed around the periphery of the X axis.
    It can be seen in FIGS. 1 and 2 that the support 4 here comprises two distinct parts 7 and 8.
    The first part 7 extends mainly radially inside the second part 8 and this first part 7 serves to physically connect the pendular damping device 2 to the hub 3, in particular by welding.
    The second part 8 serves to guide the displacement of the pendulum bodies 5, as will be seen later.
    The first part 7 is here obtained by cutting the central zone of the second part of the support 8.
    As can be seen in FIG. 1, the first portion 7 of the support 4 has, in the example described on its radially outer periphery, an alternation of solid portions 10 and empty portions 11.
    Similarly, the second portion 8 of the support 4 has on its radially inner periphery an alternation of solid portions 12 and empty portions 13.
    Because of the cutting performed, each solid portion 10 of the first portion 7 of the support has a shape complementary to the shape of each empty portion 13 of the second portion 8 of the support 4, and each solid portion 12 of the second portion 8 of the support 2 has a shape complementary to the shape of each empty portion 11 of the first portion 7 of the support 4. It is thus found that each solid portion 10 has the shape of a petal, extending radially outwardly from a ring 14 fixed on the hub 3.
    As can be seen in FIG. 2, in the assembled state, each solid portion 10 of the first portion 7 of the support 4 is axially opposite a solid portion 12 of the second portion 8 of the support 4. Similarly, each empty portion 11 of the first portion 7 of the support 4 is axially opposite an empty portion 13 of the second portion 8 of the support 4.
    Each solid portion 10 and 12 here has a through hole and the positioning of the first portion 7 and the second portion 8 of the support 4 allows to align these two holes axially, so that a screw or a rivet 15 forming a coupling is received through these two holes.
    In the example considered, the second portion 8 of the support 4 generally has a ring shape having two opposite sides which are here planar faces.
    As can be seen in FIGS. 1 and 2, each pendulum body 5 comprises in the example under consideration: two pendular masses 6, each pendulum mass 6 extending axially facing one side of the second part 7 of the support 4, and two connecting members 20 solidarisant the two pendulum masses 6.
    The connecting members 20, also called "spacers", are in the example considered angularly offset.
    In Figures 1 and 2, the pendulum damping device 2 is at rest, that is to say, it does not filter the torsional oscillations transmitted by the propulsion chain due to the acyclisms of the engine.
    In the example of the figures, each end of a connecting member 20 is welded to a pendulum mass 6. In variants, each of these ends could be force-fitted into an opening in one of the pendular masses 6 of the pendulum body 5, so as to join together these two pendular masses 6.
    Each connecting member 20 extends partly in a window 22 formed in the second part 7 of the support 4. In the example considered, the window 22 defines a void space inside the support, this window being delimited by a closed contour.
    The device 2 further comprises in the example in question rolling members 21 guiding the displacement of the pendular bodies 5 relative to the support 4. The rolling members are for example rollers.
    In the example described, the movement relative to the support 4 of each pendulum body 5 is guided by two rolling members 21, each of them cooperating in the example of the figures with one of the connecting members 20 of the body pendulum 5.
    Each rolling member cooperates here with a single first running track secured to the support 4, and with only one second running track integral with the pendulum body 5 to guide the displacement of the pendulum body 5.
    In the example considered, each second raceway is formed by a portion of the radially outer edge of a connecting member 20.
    Each first rolling track is defined by a portion of the contour of a window 22.
    Each first raceway is thus disposed radially facing a second raceway, so that the same running surface of a running gear 21 rolls alternately on the first raceway and on the second raceway. . The rolling surface of the rolling member 21 is here a cylinder of constant radius.
    As can be seen in Figures 1 and 2, the abutment damping members of the pendulum body 5 against the support 4 are provided. First abutment damping members 23 are carried by the pendulum body, each connecting member 20 being associated with a first abutment damping member 23. These first abutment damping members 23 are here configured to interpose between the associated connecting member 20 and the radially inner edge of the window 22 receiving this connecting member 20. Second stop damping members 26 are provided, being also carried by the pendulum body 5 and configured to bear against the radially outer edge of the second portion 8 of the support 4 for low radial positions of this pendulum body 5.
    As can still be seen in FIGS. 1 and 2, the component 1 also comprises, in the example under consideration, a system for attenuating the noise that occurs during an impact of the pendulum body 5 on the support 4. Attenuation system 30 is here disposed on each side of the second portion 8 of the support 4 and axially clamps the latter.
    The attenuation system 30 here comprises a first element 31 arranged axially on a first side of the second part 8 of the support 4 and a second element 32 arranged axially on a second side of this second part 8.
    This first 31 and second 32 element are here separate parts secured to the second portion 8 of the support 4, this fastening including implementing a screwing or hot riveting of plastic rivets.
    As can be seen in Figures 1 and 2, each element 31 and 32 of the attenuation system 30 has on its radially inner periphery an alternation of empty portions 33 and full portions 34. It is noted in Figure 2 that each portion full 34 of the first element 31 is axially opposite a solid portion 34 of the second element 32, while being axially opposite a void portion 11 of the first portion 7 of the support 4 and an empty portion 13 of the second portion 8 of the support 4. These solid portions 34 each have a hole 35, and these two holes are aligned to receive a screw or a rivet axially disposed in the empty portions 11 and 13 of the first and second part of the support 4 The invention is not limited to the example which has just been described.
