    [0001] The present invention relates to a device for damping torsional oscillations, in particular for a motor vehicle transmission system. In such an application, the torsion oscillation damping device may 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 motor acyclisms. Alternatively, in such an application, the torsional oscillation damping device may be integrated with a friction disk of the clutch or with a hydrodynamic torque converter. Such a device for damping torsional oscillations conventionally uses a support and one or more pendular bodies movable relative to this support. The displacement relative to the support of each pendular body is generally guided by two rolling members cooperating each on the one hand with a running track secured to the support, and on the other hand with one or more running tracks integral with the pendulum body . Each rolling member is then received in a window formed in the support and specific to this rolling member, a portion of the contour of this window forming the running track secured to the support. It is then necessary to make twice as many windows in the support as there are pendular bodies. When each pendulum body comprises two pendular masses riveted together and that these rivets are each received in a clean and distinct opening of a aforementioned window, for example according to what is disclosed in the application DE 10 2006 028 556, the number of passages in the support increases further. There is thus a need to simplify the support of a pendulum-type torsional oscillation damping device without affecting the filter performance provided by this device. The invention aims to meet this need, and it succeeds, according to one of its aspects, with a device for damping torsional oscillations, comprising: a support able to move in rotation about an axis, - a plurality of pendular bodies, each pendular body being movable relative to the support, 30 and - a plurality of rolling members, each running member cooperating with a first rolling track secured to the support and with at least one second running track secured to a pendulum body, the displacement of each pendular body relative to the support being guided by two of these rolling members, the support comprising a plurality of windows in each of which two members of are received, one of these rolling members cooperating with at least one second running track secured to one of the pendular bodies and the other of these rolling members cooperating with at least one second bearing track secured to another of these pendulum bodies, said pendular bodies being circumferentially adjacent. According to the invention, each window formed in the support receives two rolling members associated with separate pendular bodies. This reduces the number of windows to be accommodated in the support by at least two in comparison with the devices according to the prior art. Such a support is thus easier to achieve and its mechanical strength can be improved.
    [0002] Each of these windows may have a closed contour, and part of this contour may then define the first raceway with which cooperates one of the rolling members received in this window and guiding the displacement of one of the pendular bodies, while that another part of this contour defines the first rolling track with which the other rolling member received in this window co-operates and guiding the displacement of the neighboring circumferential pendulum body. 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 the device is that in which the pendulum bodies are subjected to a centrifugal force, but not to torsional oscillations from the acyclisms of the engine. 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 5 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 a "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, in particular three or six pendulous bodies. All these pendular bodies may succeed one another circumferentially. The device can 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. According to a first example of implementation of the invention, each pendulum body may comprise two first abutment damping members, each first abutment damping member circumferentially protruding towards the circumferentially adjacent pendulum body, so as to that two first abutment damping members circumferentially opposite and respectively belonging to two circumferentially adjacent pendular bodies can come into contact with each other during a displacement of these pendular bodies, each first damping member of stop being disposed in one of the windows of the support. Two first abutment damping members circumferentially facing each other and carried by circumferentially adjacent pendulums may be received at least partly in the same window of the support. Each first abutment damping member is for example exclusively contained in a window of the support. As a variant, each first abutment damping member may not only extend into a window formed in the support but also project axially from and other of this window. As will be seen later, each pendulum body may comprise two pendular masses between which the support is axially arranged, and there may then exist planes perpendicular to the axis of rotation of the support in which the first damping member stopper is disposed beyond a circumferential end of a pendulum mass. According to a second example of implementation of the invention, the device may comprise a plurality of synchronization members connecting two adjacent circumferential pendulums in pairs, each synchronizing member being disposed in one of the windows of the support. Such synchronizing members prevent the pendular bodies from making asynchronous relative movements and thus improve the damping effect. Each window of the support then receives a rolling member guiding the displacement of a pendular body, a rolling member guiding the displacement of another pendulum body 10 circumferentially neighboring, and the synchronizing member connecting said pendular bodies. Each synchronizing member may be rigidly coupled to the two pendular bodies that it connects. In a variant, each synchronizing member is articulated on each of these pendular bodies, being for example a link pivotally mounted on each of these pendular bodies. Each synchronization member may or may not be deformable. According to either of the above exemplary embodiments, each pendular body may comprise at least one second abutment damping member against the support. Each pendulum body comprises for example two second abutment damping members. Each of these second 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 position of rest, or - at the end of a displacement in the non-trigonometric direction of this pendulum body from the rest position, or - in the event of a radial fall of the pendulum body, for example when stopping the engine of the vehicle. Where appropriate, each second abutment damping member can damp the abutment of the pendulum body against the support at the end of a movement in the trigonometrical or non-trigonometric direction respectively from the rest position, but also in case radial fall of the pendulum body. Each first and second abutment damping members may have resilient properties for damping shocks associated with 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. According to the first exemplary embodiment of the invention, each first abutment damping member and a second abutment damping member may form different parts of a single piece. In other words, each pendulum body can then comprise at each of its circumferential ends a part: a portion of which circumferentially projects in the direction of the neighboring pendulum body circumferentially, so as to form a first abutment damping member, and - Of which another part forms a second abutment damping member. According to the second exemplary embodiment of the invention, each synchronizing member and each second abutment damping member can form different parts of one and the same piece. In other words, each pendulum body may comprise at each of its circumferential ends a part: a part of which forms a synchronizing member, another part of which forms a second abutment damping member of this pendulum body, and - Another part extends into the circumferentially adjacent pendulum body and forms a second abutment damping member of the circumferentially adjacent pendulum body. In all of the foregoing, each pendular body may comprise: a first and a second pendular mass axially spaced relative to each other, the first pendular mass being disposed axially on one side of the support and the second pendulum mass being arranged axially on a second side of the support, and - at least one connecting member of the first and second pendulum masses, matching said masses. In this case, the second abutment damping member may extend around all or part of a connecting member. Each pendulum body may extend angularly over a global angle value measured from the axis of rotation between two circumferential ends which correspond to the circumferential ends of the pendulum masses of this body, each second raceway being arranged inside. an angular sector measured from the axis of rotation and extending from a circumferential end of the pendulum body towards the other circumferential end of this pendulum body, the ratio between this angular sector and the overall angle being comprised between 1/15 and 1/2, being for example between 0.1 and 0.25. Such a position of the second rolling tracks makes it possible to angularly offset each running member the outermost of the pendulum body. In this way, the movement of each pendulum body is more precise and more stable with constant manufacturing tolerance.
    [0003] The amplitude of the deflection of each pendulum body can moreover be increased. Such a position of the rolling members can further increase the polar inertia of the pendulum body, which is advantageous when this pendulum body has the aforementioned combined movement. The second integral running track of the pendulum body may be defined by the connecting member. A portion of the contour of this connecting member defines for example the second rolling track. 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 via its axial ends to each pendulum mass. Each pendular body may then comprise two connecting members matching the first and second pendulum masses, each connecting member defining a second raceway cooperating respectively with one of the two rolling members guiding the displacement of the pendular body relative to to the support. Each rolling member then cooperates with a single second raceway. In this case, each window receiving two rolling members may also receive a connecting member of a pendulum body and a connecting member of the pendulum body circumferentially adjacent. In each window is then: - a connecting member of a pendular body and a rolling member guiding the displacement of the pendulum body, and - a connecting member of another pendular body and a rolling member guiding the 20 displacement of this other pendulous body. Each rolling member can then be stressed only in compression between the first and second raceways mentioned above. These first and second race tracks cooperating with one and the same rolling member may be at least partly radially opposite, that is to say that there are planes perpendicular to the axis of rotation in which these tracks of rolling both extend. Such a device for damping torsional oscillations thus has a number of passages formed in the very reduced support since, for a number n of pendular bodies, n windows allow the guidance of these n pendular bodies and the connection between the pendular masses of each of these pendular bodies. When the second raceways are offset angularly outwardly from the pendular bodies, as mentioned above, these windows may have a particularly small angular dimension. As a variant, each rolling member may cooperate with two second race tracks integral with the pendulum body, one of these second raceways being defined by the first pendulum mass and the other of these second raceways being defined by the second pendulum mass. Each connecting member is then for example a rivet, being received 3036762 7 in a different opening of the support of the window in which a rolling member is received. Each rolling member can then comprise successively axially: a portion disposed in a cavity of the first pendulum mass and cooperating with the second rolling track formed by a portion of the contour of this cavity, a portion disposed in a window of the support and cooperating with the first rolling track formed by a portion of the contour of this window, and - a portion disposed in a cavity of the second pendulum mass and cooperating with the second raceway formed by a portion of the contour of this cavity. According to this variant, each pendular body may comprise at least one, in particular two, connecting member matching the first and the second pendulum masses, all the connecting members of this pendulum body being arranged in the angular space defined between the two organs. rolling guide the displacement of the pendulum body relative to the support. The connecting member or members may then be arranged in the central zone, angularly speaking, of the pendulum body.
    [0004] Still according to this variant in which two second races integral with the pendular bodies are provided, but alternatively to the preceding paragraph, it is possible that all or part of the connecting members of the pendulum body are received in windows already receiving running gear. Each window formed in the support receives, for example, then: a connecting member of a pendular body and a rolling member guiding the displacement of this pendulum body, and a connecting member of another pendular body and an organ rolling guide the movement of this other pendulous body. In this case, the rolling members are then arranged radially outwardly with respect to the connecting members. Similarly to what has been mentioned above, the number of openings in the support for guiding the pendular bodies and the connection between the pendular masses of each of these pendular bodies is then particularly reduced. In all the foregoing, the device may comprise at least one interposition piece of which at least one part is axially arranged between the support and a pendulum mass of the pendular body. 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.
    [0005] 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. The interposition pieces can be positioned on a pendulum body so that there is always at least one interposition piece at least part of which is axially interposed between a pendulum mass and the support, whatever the relative positions of the support and said mass when moving relative to the support of the pendulum body. In all the foregoing, the device may comprise: at least one first pendular body for filtering a first order value of the torsional oscillations, and at least one second pendular body for filtering a second order value. torsional oscillations, different from the first order value. 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 damper 15, a hydrodynamic torque converter or a friction clutch disc , comprising a device for damping torsional oscillations as defined above. The support of the torsion oscillation damping device can then be one of: - a component web, - a component guide washer, - a component phasing washer, or - a separate support of said web , said guide washer and said phasing washer. 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 torsion oscillation damping device according to a first example of implementation of the invention, - Figure 2 is a detail of Figure 1, - Figure 3 is a view similar to Figure 2 of a FIGS. 4 and 5 are different views of a variant of the second embodiment of the invention; FIG. torsion damping device according to the invention, and - Figures 7 and 8 show a detail of another device for damping torsional oscillations according to the invention.
    [0006] FIG. 1 shows a device 1 for damping torsional oscillations according to an embodiment of the invention. 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 an unrepresented component of such a transmission system, this component being for example a double damping flywheel, a hydrodynamic torque converter or a clutch disk. This component can be part of a propulsion system of a motor vehicle, the latter comprising a thermal engine including three or four cylinders.
    [0007] In FIG. 1, the device 1 is at rest, that is to say that it does not filter the torsional oscillations transmitted by the propulsion chain because of the acyclisms of the heat engine. As known, such a component may comprise a torsion damper having at least one input member, at least one output member, and circumferentially acting elastic return members which are interposed between said input and output elements. exit. 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 in question: a support 2 capable of moving in rotation about an axis X, and a plurality of pendular bodies 3 movable relative to the support 2. In the example under consideration, six Pendulum bodies 3 are provided, being uniformly distributed around the periphery of the axis X. The support 2 of the damping device 1 can be constituted by: an input element of the torsion damper; an output element or an intermediate phasing element disposed between two series of spring of the damper, - an element connected in rotation to one of the aforementioned elements and distinct from the latter, then being for example a support specific to the device 1.
    [0008] 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 solidifying the two pendulum masses 5. In FIGS. 2 and 3, one of the pendulum masses 5 is not shown, so as to better see the support 2. The connecting members 6, still called "spacers", are in the example considered angularly offset. Each connecting member 6 is here offset angularly towards the outside of each pendulum body 3. Each body 3 extends angularly over a global angle value a measured from the axis of rotation X of the support 2 between two circumferential ends, which respectively correspond to the circumferential ends 7 and 8 of the pendulum masses 5 of this body, and each connecting member 6 is then disposed within a peripheral zone 9 of the pendulum body, this peripheral zone 9 extending from a end 7 or 8 of the pendulum body 3 towards the other end 8 or 7 of this pendulum body on an angular sector 13 measured from the X axis, the ratio (3 / a being between 1/15 and 1/2 , being in particular between 0.1 and 0.25, in other words, and as can be seen in particular in FIG. 1, each pendulum body 3 comprises, in the example described, when one moves inside the this pendulair body e 3 from a circumferential end 7 to its other circumferential end 8 successively: - a peripheral zone 9 in which is disposed one of the connecting members 6 of the pendulum body 3, - a central zone 10 devoid of a connecting member 6, and - Another peripheral zone 9 in which is disposed the other connecting member 6 of the pendulum body 3. In the example of Figures 1 to 5, each end of a connecting member 6 is force-fitted into an opening 17 arranged in one of the pendulum masses 5 of the pendulum body 3, so as to join together these two pendulum masses 5. Alternatively, each end of a connecting member is secured to one of the pendulum masses 5 by welding. The device 1 also comprises rolling members 11 guiding the displacement of the pendular bodies 3 relative to the support 2. The rolling members 11 are here rollers 30 having several different successive diameters. 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. As shown in the figures, two rolling members 11 associated with two different and circumferentially adjacent pendulum bodies 3 are received in the same window 19 formed in the support 2. In other words, within the same window 19, a transmission member is received. bearing 11 guiding the displacement of a pendulum body 3 and a rolling member 11 guiding the displacement of another pendulum body 3 which is circumferentially adjacent. Each window 19 has a closed contour 16 and a portion of this contour 16 defines a first rolling track 12 integral with the support 2, on which one of the rolling members 11 received in this window 19 will roll, while another part of this closed contour 16 defines another first rolling track 12 secured to the support 2, on which the other rolling member 11 received in the window 19 will roll. In the example of Figures 1 to 5, each window 19 also receives: - a connecting member 6 of a pendulum body 3, and - a connecting member 6 of another pendulous body 3 which is circumferentially adjacent. Each connecting member 6 defines in the example of Figures 1 to 5 a second rolling track 13 which is integral with the pendulum body 3 which this connecting member 6 belongs and on which rolls one of the rolling members 11 to guide the movement of this pendulum body 3 with respect to the support 2. In the example of FIGS. 1 and 2, synchronization members 20 are provided. Each synchronizing member 20 is here interposed between two pendulum bodies 3 circumferentially neighboring it connects them. Each synchronizing member 20 is here integral with each of the pendular bodies 3 that it connects.
    [0009] Each pendulum body 3 also comprises two second abutment damping members 25 of this pendulum body against the support 2. One of these second abutment damping members 25 comes into contact, for example, with the support 2 at the resulting from a movement in the counterclockwise direction of the pendulum body 3 from its rest position, and also in the event of a radial fall of this pendulum body 3, while the other second stop damping member 25 comes into contact with the support 2 at the end of a displacement in the non-trigonometric direction of the pendular body 3 from its rest position, and if necessary also in the event of a radial fall of this pendulum body 3. Each second damping member of stop 25 is for example radially positioned between a connecting member 6 and the contour 16 of the window 19. Each second stop damping member 25 extends in the example of Figures 1 and 2 between two extremes axial threads, each of which is received in a hole in one of the pendulum masses 5, so as to secure this second abutment damping member 25 to each of these pendulum masses 5.
    [0010] As can be seen in FIG. 2, each second abutment damping member 25 may be made of several parts, and one of these parts may form a single piece with a synchronizing member 20, this part being here in elastomer. Figures 3 to 5 show different variants of a second example of implementation 5 of the invention. In FIGS. 3 to 5, one of the pendulum masses 5 of the pendulum body 3 is not shown. This second example of implementation differs from that described with reference to Figures 1 and 2 in that the device 1 is devoid of synchronizing members 20. Each pendulum body 3 comprises according to this second example two first damping members of stop 30, each first abutment damping member 30 circumferentially protruding beyond one of the circumferential ends 7 and 8 of the pendulum body 3 towards the circumferentially adjacent pendulum body 3. In this way, two first abutment damping members 30 circumferentially opposite and respectively belonging to two circumferentially adjacent pendulous bodies 3 may come into contact with each other during a displacement of these pendulum bodies 3. These first 15 circumferentially opposite abutment damping members 30 are, as shown in FIG. 3, received in the same window 19 formed in the support 2. As can be seen in FIGS. 3 to 5, each first member of FIG. The abutment damping 30 is at least partially disposed in a window 19. Again according to FIGS. 3 to 5, each first abutment damping member 30 is made in one piece with all or part of a second housing member. 25 This piece is for example made of elastomer or rubber. In the example of FIG. 3, each first abutment damping member 30 extends exclusively inside a window 19. In the example of FIGS. 4 and 5, each first abutment damping member 30 extends not only inside a window 19, but also axially on either side of this window 19. Each first abutment damping member 30 extends for example along an circumferential end 7 or 8 of the pendulum body 3. As can be seen in Figure 5, when each second abutment damping member 25 is in one piece, a single piece can form both a first member 30 of stop damping 30 and a second stop damping member 25. Reference will now be made to FIGS. 6 to 8 of other examples of torsion oscillation damping devices 1 according to the invention. The examples of FIGS. 6 to 8 differ from what has been described with reference to FIGS. 1 to 5 in that each rolling member 11 cooperates with two second raceways 13 which are not defined by a connecting member 6. One of these second raceways 13 is defined by a portion of the contour 35 of a recess 35 formed in the first pendulum mass 5 while the other of these second raceways 13 is defined by a portion of the contour of a cavity 35 formed in the second pendulum mass 5 of the pendulum body 3. Each rolling member 11 comprises successively axially in the example of Figure 7: - a portion disposed in a cavity 35 of the first pendulum mass 5 and cooperating with the second raceway 13 formed by a portion of the contour of this cavity 35, - a portion disposed in a window 19 of the support 2 and cooperating with the first raceway 12 formed by a portion of the contour of this window 19, and 10 - a portion disposed in a cavity 35 of the second pendulum mass 5 and cooperating with the second raceway 13 formed by a portion of the contour of this cavity 35. Each body pendulum 3 further comprises connecting members 6 matching the two pendulum masses 5 of the pendulum body 3, but these connecting members 6 are different from those described with reference to Figures 1 to 6. The connecting members 6 are here rivets. Each rivet 6 is for example provided with a stop damping member 45 visible in Figure 7, the latter being in the form of a ring made of a material such as elastomer. In the example of FIG. 6, the rivets 6 are arranged in the central zone 10 of a pendular body 3 and pass through a cavity of the support 2 different from a window 19. Each pendulum body 3 comprises in this example two rivets 6 which are angularly surrounded on each side by a rolling member 11. Similarly to what has been described above, each window 19 formed in the support receives on the one hand a rolling member 11 guiding the displacement of a pendulum body 3 and on the other hand a rolling member 11 guiding the displacement of another pendulum body 3 circumferentially neighboring. FIGS. 7 and 8 differ from what has just been described with reference to FIG. 6 in that rivets 6 are also received in windows 19. In other words, and as can be seen in FIG. each window formed 19 in the support 2 then receives: - a rivet 6 of a pendular body 3 and a rolling member 11 guiding the displacement of this pendulum body 3, and - a rivet 6 of another pendulum body 3 and a bearing member 11 guiding the displacement of this other pendulum body 3. In FIG. 7, the pendular bodies 3 are not completely represented, one of the pendulum masses 5 of each pendulum body 3 not being represented, for reasons for clarity of the drawing. Although not shown in FIGS. 6 to 8, the device 1 according to these figures may comprise synchronizing members similar to those described with reference to FIGS. 1 and 2 or the first 14 abutment damping members similar to those described. with reference to FIGS. 3 to 5. The invention is not limited to the examples which have just been described.
