    PENDULAR DAMPING DEVICE
    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 known as the double damping flywheel.
    Alternatively, in such an application, the pendulum damping device may be integrated with a friction disc of the clutch or with a hydrodynamic torque converter.
    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 pendular bodies. Each pendulum body comprises for example two pendular masses riveted together.
    It is known to choose the damping device, for example via the shape of the rolling tracks, so that the latter filters the excitation order of a two-cylinder combustion engine of the vehicle, also called "order 1 ", the order of excitation of a thermal engine being in known manner the number of explosions of this engine per revolution of crankshaft. Such devices are very sensitive to the force of gravity, the latter can then cause unwanted displacements of the pendular bodies, and thus affect the filter performance.
    To remedy this problem, it is for example known from the application DE 10 2012 221 103 to provide springs between two circumferentially adjacent pendulum bodies, so that the pendular bodies thus connected resist the force of gravity exerted alternately on the latter when the device is driven by a rotational movement. The insertion of these springs supposes to provide additional housings in the pendular bodies or to provide appropriate fastening means on these pendular bodies, which is expensive and complex. Due to the insertion of the springs, an additional resonant frequency appears elsewhere. The insertion of the springs may still require cutting open cutouts in the support of the device, thereby reducing the movement of the pendular bodies. In addition, it is necessary to correctly size the springs and the maintenance of the characteristics of the springs in time is not guaranteed. The object of the invention is to reduce the influence of gravity on the pendular bodies, in particular when the latter are intended to filter the excitation order of a two-cylinder combustion engine of the vehicle, while at the same time remedying all or some of the disadvantages above. The invention aims to meet this need, and it succeeds, according to one of its aspects, with the aid of a pendulum damping device, comprising: a support able to move in rotation around an axis, - at least one pendular body comprising: a first and a second pendular masses axially spaced relative to each other and movable relative to the support, the first pendular mass being arranged axially on a first side of the support and the second pendular mass being arranged axially on a second side of the support, and at least one connecting member of the first and second pendular masses matching said masses, and - at least one rolling member guiding the displacement of the pendulum body relative to the support, the rolling member cooperating on the one hand with a running track secured to the support and on the other hand with a running track secured to the pendulum body and defined by the connecting member, the rolling member exerting an axial clamping force on at least one of the pendulum masses during the displacement of the latter relative to the support.
    According to the invention, the axial clamping exerted by the rolling member on the pendulum mass, and therefore on the pendulum body, opposes the displacement of this pendulum body under the effect of gravity and thus hinders the action of gravity on this pendulum body. When the support rotates, each pendular body successively occupies the highest position around the axis of rotation of the support. The downward movement of the uppermost pendulum body is thus reduced by the rolling member which exerts on the pendulum body an axial clamping.
    For the purposes of the present application: - "axially" means "parallel to the axis of rotation of the support" or "parallel to the longitudinal axis of the rolling member", as appropriate, - "radially" means "the 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 the device is that in which the pendular bodies are subjected to centrifugal force, but not to oscillations of torsion from the acyclisms of the engine. The rolling member may exert an axial clamping force on only one of the pendular masses of the pendulum body, during the displacement of the pendulum body relative to the support.
    Alternatively, the rolling member may exert an axial clamping force on each pendular mass of the pendulum body during the displacement of the pendular body relative to the support. This reinforces the action exerted by the rolling member on the pendulum body to hinder the action of gravity on the pendulum body.
    According to a first example of implementation of the invention, the rolling member carries on at least one of its axial end faces a resilient axial bearing member exerting axial clamping on the pendulum mass. This axial clamping can be exerted over the entire range of displacement of the pendular body relative to the support. According to this first example, a washer may be mounted on the axial end face of the rolling member and the elastic axial bearing member may be formed by at least one leg of this washer. In this case, the washer is received in the axial end face of the rolling member facing the pendulum mass and axially clamped. The washer is for example fixed on the rolling member.
    In the case where the rolling member axially clamps only one pendular mass of the pendular body, this rolling member may have an axial end face of a shape different from that of its other axial end face, this difference of form being due to the reception of the washer on only one of these axial end faces. The other axial end face does not then come into contact with the other pendular mass of the pendulum body.
    In the case where the rolling member axially clamps each pendular mass of the pendular body, this rolling member may carry two separate washers, each washer being mounted on an axial end face of the rolling member and clamping axially via its paw the pendular mass of the pendular body which is axially opposite this axial end face.
    In the case where the rolling member axially clamps each pendular mass of the pendulum body, this rolling member may have a first axial end face accommodating a washer axially clamping via its leg the pendular mass of the pendular body which is axially opposite. of this first face, and a second axial end face bearing a protrusion coming into contact with the pendular mass of the pendular body which is axially opposite said second axial end face, so as to axially clamp the pendulum mass.
    According to this first example, the washer may be elastically deformable, so as to allow its mounting in a housing formed in the axial end face of the rolling member. This elastic deformation of the washer can be done in a plane perpendicular to the axis of rotation of the rolling member, when mounting the washer in the housing.
    The washer is for example made of alloy steel for spring.
    According to this first example, the washer may comprise: an annular radially outer portion extending circumferentially, and the tab extending from the radially outer annular portion towards the inside of the washer.
    The lug may project axially relative to the annular radially outer portion of the washer, at least before installation of the washer on the axial end face of the rolling member.
    The radially outer annular portion can extend continuously, that is to say form an uninterrupted ring. It may be a Belleville washer.
    In a variant, the annular radially outer portion of the washer may extend discontinuously, being split. The slot may have a variable circumferential extent. The slot extends for example on an angle measured between its two ends from the center of the annular outer portion of the washer and which is between 10 ° and 120 °, being in particular between 40 ° and 90 °, more particularly included between 50 ° and 70 °.
    When such a slot exists, the tab of the washer can be substantially rectilinear and have its free end facing the slot.
    In a variant, when such a slot exists, two distinct tabs may be defined by the washer. The slot extends for example between two returns extending towards the inside of the washer from its radially outer annular portion, and each return forms a tab.
    According to a second example of implementation of the invention, the rolling member is hollow so as to define a housing in which is received a spring, at least one end of this spring forming the elastic member of axial support. This accommodation can be one-eyed. One of the ends of the spring can be fixed to the bottom wall of this terminal housing while the other end of the spring protrudes out of the housing and bears axially on one of the pendulum masses, so as to exert the aforementioned axial clamping.
    In the case where the axial clamping is exerted by the rolling member on only one of the pendular masses of the pendular body, a single blind housing can be formed in the rolling member and a single spring is thus received in the body of the rolling.
    In the case where the rolling member exerts an axial clamping on each pendular mass of the pendulum body, two blind housings not communicating with each other can be formed in the rolling member. Each blind housing can then receive a spring having one end fixed to the bottom wall of this blind housing and another end protruding from this housing and pressing axially on one of the pendulum masses, so as to exert the axial clamping above. .
    In a variant of the case where the rolling member exerts an axial clamping on each pendulum mass, the housing formed in the rolling member may be through, so that each end of the spring received in this housing forms an elastic member of axial support on one of the respective pendulum masses of the pendulum body.
    We will now mention characteristics that can indifferently apply to one of the implementation examples mentioned above.
    Each rolling member may cooperate with the running track secured to the support and with the or running tracks integral with the pendulum body only via its outer surface. Thus, the same portion of this outer surface may roll alternately on the running track secured to the support and on a running track integral with the pendulum body when the running member moves.
    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.
    The shape of the first and second rolling tracks may be such that each pendulum 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 body, such a movement being again called "combined movement" and disclosed for example in the application DE 10 2011 086 532.
    The device comprises for example a number between two and eight, including three 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 of the above, the support can be made in one piece, being for example entirely metallic.
    As mentioned above, the integral running track of the pendular body is here defined by the connecting member of the pendulum 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 via its axial ends to each pendulum mass.
    Each pendulum body comprises for example two connecting members matching each pendulum mass of the body, each connecting member being integral with each of these pendular masses. 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.
    Each rolling member can be received in a window of the support receiving no other rolling member. This window is for example defined by a closed contour, a portion of the edge defines the rolling track secured to the support and cooperating with this rolling member.
    The displacement of each pendular body relative to the support can be guided by at least two rolling members, including exactly two rolling members. In this case, each rolling member exerts an axial clamping on at least one of the pendular masses of the pendulum body. For example, each rolling member exerts only axial clamping on the first pendulum mass of the pendular body, without exerting axial clamping on the second pendulum mass of the pendulum body. In a variant, each rolling member exerts an axial clamping on each of the pendular masses of the pendulum body. In another variant, only one of the rolling members guiding the displacement of the pendular body exerts an axial clamping on the pendular mass or masses of this pendulum body.
    Each rolling member exerts on the pendulum body with which it interacts, an axial clamping force of 0.5 N. The overall clamping force, expressed in Newtons, exerted by all the rolling members guiding the displacement of a pendulum body by relative to the support may be between 20% and 110% of the weight, expressed in Newtons, of this pendulum body. Preferably, this clamping force is between 50% and 90% of the weight of the pendulum body, in particular between 60% and 80% of this weight.
    In all the foregoing, the device may comprise at least one interposition piece of which at least a portion is axially disposed between the support and a pendular mass of the pendular body. The interposition piece is for example fixed on a pendular mass or the support or formed by a coating deposited on a pendular mass or on the support. Such an interposition piece can thus limit the axial displacement of the pendular body relative to the support, thus 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. Several interposition pieces, for example in the form of pads, may be provided. The interposition pieces are in particular made of a damping material, such as plastic or rubber.
    The interposition pieces are for example carried by the pendular bodies, being in particular fixed on the pendular bodies. The interposition pieces can be positioned on a pendular body so that there is always at least one interposition piece at least a portion of which is axially interposed between a pendulum mass and the support, whatever the positions relative to the support and said mass when moving relative to the support of the pendulum body.
    In all of the above, each pendular body may comprise at least one abutment damping member against the support. Each of these abutment damping members can then come into contact with the support to damp the abutment of the pendulum body against the latter, for example: - at the end of a displacement in the counterclockwise direction of this pendulum body from the rest position for filtering a torsional oscillation, and / or - following a displacement in the non-trigonometric direction of this pendulum body from the rest position to filter a torsional oscillation, and / or - in case radial drop of the pendulum body, for example when stopping the engine of the vehicle.
    Where appropriate, each abutment damping member can damp the stop of the pendulum body against the support at the end of a movement in the counterclockwise direction from the rest position, after a displacement in the direction non-trigonometric since the rest position but also in case of radial fall of the pendulum body. The same abutment damping member can thus be associated with a pendulum body for damping all the abovementioned contacts between the pendulum body and the support.
    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 then have a cylindrical shape with an axis parallel to the axis of rotation of the support.
    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 abutment damping member is for example elastomer or rubber. The invention further relates, in another of its aspects, a component for a transmission system of a motor vehicle, the component being in particular a double damping flywheel, a hydrodynamic torque converter or a clutch friction disc, comprising a pendulum 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. According to another of its aspects, the subject of the invention is also a vehicle powertrain comprising: a propulsion engine of the vehicle, in particular with two, three or four cylinders, and a component for a transmission system defined above. 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. 1 schematically represents a pendulum damping device according to an exemplary implementation of the invention, - Figure 2 partially a first embodiment of the invention, when the device is at rest, - Figure 3 is a view 2 to 6 schematically represent three washer variants with respect to that shown in FIG. 2, and FIG. 7 is similar to FIG. partial a second example of implementation of the invention, when the device is at rest.
    There is shown in Figure 1 a pendulum damping device 1.
    The damping device 1 is of the pendulum oscillator type. The device 1 is particularly suitable for equipping a motor vehicle transmission system, being for example integrated with a component not shown of such a transmission system, this component being for example a double damping flywheel, a hydrodynamic torque converter or a clutch friction disc.
    This component can be part of a powertrain of a motor vehicle, this group comprising a thermal engine including two, three or four cylinders.
    In Figure 1, the device 1 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 known manner, such a component may comprise a torsion damper having at least one input element, at least one output element, and circumferentially acting resilient return members which are interposed between said input and output elements. . For the purposes of the present application, the terms "input" and "output" are defined with respect to the direction of torque transmission from the engine of the vehicle to the wheels of the latter.
    The device 1 comprises in the example under consideration: a support 2 able to move in rotation about an axis X, and a plurality of pendular bodies 3 movable relative to the support 2.
    According to the examples of implementation of the invention which will be described later, the support 2 is unique. It will also be observed in FIG. 1 that three pendulous bodies 3 are provided, being uniformly distributed around the periphery of the X axis.
    The support 2 of the damping device 1 may consist of: - an input element of the torsion damper, - an output element, - an intermediate phasing element disposed between two sets of spring of the damper, or - an element linked in rotation to one of the aforementioned elements and distinct from the latter, then being for example a support specific to the device 1.
    The support 2 is in particular a guide washer or a phasing washer. The support may be other, for example a flange of the component.
    In the example considered, the support 2 generally has a ring shape having two opposite sides 4 which are here planar faces.
    As can be seen in particular in FIG. 1, each pendulum body 3 comprises in the example under consideration: two pendulum masses 5, each pendulum mass 5 extending axially facing one side 4 of the support 2, and two connecting members 6 solidarisant the two pendulum masses 5.
    In FIGS. 2 and 7, one of the pendulum masses 5 is not shown, so as to better see the support 2. In FIG. 3, the support 2 is not shown while the two pendulum masses 5 of FIG. pendulum body 3 are.
    The connecting members 6, also called "spacers", are in the example considered angularly offset.
    In the example of Figure 1, each connecting member 6 is secured to the pendulum masses 5 being force-fitted via each of its ends in an opening 17 formed in one of the pendulum masses 5. In variants not shown, each member link 6 can be screwed onto each pendulum 5, or each end of a connecting member 6 is secured to one of the pendulum masses 5 by welding.
    The device 1 also comprises rolling members 11 guiding the displacement of the pendulum bodies 3 relative to the support 2. The rolling members 11 are here rollers with or without several successive different diameters. Each rolling member 11 thus has a longitudinal axis Y parallel to the axis of rotation X of the support 2.
    In the example described, the movement relative to the support 2 of each pendulum body 3 is guided by two rolling members 11.
    Each rolling member 11 is received in a window 19 formed in the support 2. In the examples considered, each window 19 receives only one rolling member 11.
    Each rolling member cooperates on the one hand with a running track 12 integral with the support 2 and which is here formed by a portion of the edge of the window 19, and on the other hand with a rolling track 13 integral with the pendulum body 3 and defined by a portion of the radially outer edge of the connecting member 6.
    The device 1 further comprises stop damping members 20 which are visible in Figures 2 and 7. Each connecting member 6 is in the examples described associated with two separate abutment damping members 20. Each of these abutment damping members 20 has here an elongated shape along an axis parallel to the axis Y. Each abutment damping member 20 is here received in a recess 21 formed in a lateral edge of the link 6. Each abutment damping member 20 extends between two ends 22, each of these ends 22 being integrally received in a not shown housing of the pendular mass 5 axially opposite this end 22, so as to the stop damping member 20 is secured to the pendulum body 3. One of the abutment damping members 20 is positioned so as to damp the shocks associated with the abutment of the pendulum body 3 against the support 2 to the from a trigonometric movement from the home position of FIGS. 2 and 7 for filtering a torsional oscillation. The other abutment damping member 20 is positioned so as to damp the shocks associated with the abutment of the pendular body 3 against the support 2 at the end of a displacement in the non-trigonometric direction from the rest position. Figures 2 and 7 for filtering a torsional oscillation.
    Each abutment damping member 20 is in the example considered made of rubber.
    In variants, the abutment damping members may be other. Two abutment damping members 20 associated with the same connecting member 6 can thus be connected to each other by a bridge of material. In a variant, a single abutment damping member is associated with one and the same connecting member 6, this single abutment damping member damping the shocks between the pendulum body 3 and the support 2: at the end of a displacement in the counterclockwise direction of this pendulum body 3 from the rest position to filter a torsional oscillation, and - at the end of a displacement in the non-trigonometric direction of this pendulum body from the rest position to filter an oscillation torsion, and - in case of radial drop of the pendulum body, for example when stopping the engine of the vehicle.
    Two examples of implementation of the invention will now be described more specifically, with reference to FIGS. 2, 2, 4, 4, 4, 4, 4, 4 and 5, in which axial clamping is exerted on each pendulum body 3 in order to impede the action of gravity on this pendulum body. 3.
    In the examples of implementation which will be described, the axial clamping is exerted on each pendulum body 3 of the device 1 by the two rolling members 11 guiding the displacement relative to the support 2 of this pendulum body 3.
    According to the first example of implementation, described with reference to Figures 2 to 6, this axial clamping is exerted via an elastically deformable washer 25. A single elastically deformable washer 25 is here mounted on a rolling member 11. This rolling member 11 then has two axial end faces 27 of different shape, as can be seen in Figure 3. One of these axial end faces 27 is here hollow so as to define a housing 30 accommodating the elastically deformable washer 25, while the other axial end face 27 of the rolling member 11 is curved, having a protrusion 28 bearing axially against the pendular mass 5 axially facing this other axial end face 27.
    In this example, the other axial end face 27 does not accommodate an elastically deformable washer 25.
    The elastically deformable washer 25 is in this example made of alloy steel for spring. The washer 25 can be deformed in a plane perpendicular to the axis Y according to the arrows of Figure 5 when it is placed in the housing 30, so as to be maintained in this housing 30 once returned to its original shape.
    According to the four washer variants 25 shown in FIGS. 2, 4, 5 and 6, the elastically deformable washer 25 comprises: an annular radially outer portion 35 extending circumferentially, and at least one tab 37 extending from the annular radially outer portion 35 towards the inside of the washer and projecting axially with respect to this annular radially outer portion 35.
    In the examples of Figures 2, 4 and 5, the radially outer annular portion 35 extends discontinuously, being split. As can be seen, different circumferential extent values of slot 40 are possible. In the example of Figure 2, the slot 40 extends over an angle measured between its two ends from the center of the annular outer portion 35 of the washer 25 which is very small, being for example between 10 ° and 40 °. As a variant, the slot may be arranged at a larger angle, for example at an angle α of the order of 80 °, as shown in FIG.
    In the examples of FIGS. 2 and 4, the tab 37 is substantially rectilinear and its free end 41 is opposite the slot 40.
    In the example of Figure 5, the slot 40 is defined between two returns extending inwardly of the elastically deformable washer 25 from the radially outer annular portion 35. Each of these returns then defines a tab 37.
    In the example of Figure 6, the radially outer portion 35 of the washer 25 extends continuously, being devoid of slit. The elastically deformable washer 25 is for example a Belleville washer.
    In each of the examples described with reference to FIGS. 2 to 6, the lug (s) 37 carried by a rolling member (11) bear axially elastic support against a pendulum mass (5) of the pendulum body (3), so as to exert an axial clamping on this body. pendulum 3.
    A second exemplary implementation of the invention will now be described with reference to FIG. In this example, a through housing 50 is formed in each rolling member 11, between the two axial end faces 27 of the rolling member 11. This housing 50 receives a spring 51, each end 52 projects axially out of the housing 50. Each end 52 of the spring 51 forms, according to this second example of implementation, an elastic element for axial support on a pendular mass 5 of the pendular body 3, making it possible to exert an axial clamping on this pendulum body 3.
    In all the foregoing, the axial clamping can be exerted on the pendular body for any position of the latter relative to the support 2, that is to say that there is then no range of displacement of the pendulum body 3 relative to the support 2 in which no axial clamping is exerted by the rolling members 11 guiding the displacement of the pendulum body 3 on the latter. In all of the above, axial clamping can be of constant value. As a variant, the value of the axial clamping may vary during the displacement of the pendular body 3 with respect to the support 2.
    As a variant, the axial clamping is exerted on the pendulum body only in certain positions of the pendulum body 3 with respect to the support, that is to say that there exists one or more ranges of displacement in which no axial clamping n is exerted by the rolling members 11 guiding the displacement relative to the support 2 of the pendulum body 3.
    In all the foregoing, the overall clamping force, expressed in Newtons, exerted by all the rolling members guiding the displacement of a pendulum body relative to the support can be between 20% and 110% of the weight, expressed in Newtons. of this pendular body. Preferably, this clamping force is between 50% and 90% of the weight of the pendulum body, in particular between 60% and 80% of this weight. To obtain such a clamping force, one can play on the value of the coefficient of friction occurring during this tightening. The invention is not limited to the examples which have just been described.
    For example, according to the first example of implementation, the washer 25 may not be fully elastically deformable, only the tab 37 or only the tabs 37 having this elastically deformable nature.
