    Device for damping torsional oscillations
    The present invention relates to a torsion oscillation damping device in particular adapted to be integrated in a transmission chain of a motor vehicle.
    Such a device may comprise a torque limiter. It is in particular known to rivet friction linings of this torque limiter on a disc. In such cases, each liner has an oversized thickness. Indeed, it is necessary to have sufficient thickness between the rivets and the friction surface of the linings to prevent the rivet heads from rubbing and degrading the damping device of torsional oscillations when the linings wear out. .
    It is also necessary to have sufficient thickness between the rivets and the disk to allow the holding of these rivets.
    It is necessary to provide a minimum of material around the holes related to the rivets to preserve the integrity of the seal. Finally, these holes, opening, reduce the friction surface.
    US Pat. No. 2013116054 also discloses a device for damping torsional oscillations, in particular comprising a torque limiter, a torsional torsional oscillation damping device and an additional torsional vibration damper, both rotating around a single torsion oscillator. axis. The additional torsion oscillation damper comprises in particular an input element, an output element and springs between these input and output elements opposing the relative pivoting of these two elements.
    In such a device, the torsional torsional oscillation damper is positioned radially above the torque limiter. Such a device therefore does not have a compactness, especially not a satisfactory radial compactness. The invention aims to improve this type of device. The invention thus relates in particular to a device for damping torsional oscillations, in particular for a motor vehicle transmission chain, comprising: a shock absorber for oscillating torsional oscillations; an absorber for additional torsional oscillations , comprising an input member, an output member, both rotatable about an axis of rotation and at least one mechanical energy accumulator member arranged between the input and output members, and - a torque limiter comprising at least one friction lining fixed on a disk integral in rotation with the input element of the additional torsional oscillation damper, characterized in that the lining is fixed to the limiter disk in a surface connection, in particular a surface bond by adhesion. The combined action of the two dampers makes it possible to obtain a satisfactory damping of the torsional oscillations by the device.
    Thanks to this surface connection, the torque limiter is devoid of intermediate solid part, source of axial size. The invention makes it possible in particular to limit the axial size of the limiter at the level of the lining. Indeed, compared to a device in which the lining is riveted to the limiter disk, the thickness of the lining of the device according to the invention is reduced by the thickness of the rivet head and a thickness related to the counterbore of the filling.
    According to the invention, it is possible to minimize the radial thickness of the friction lining while having an identical friction surface, the holes linked to the rivets being non-existent.
    The reduced axial dimension of the torque limiter at the level of the friction lining makes it possible to have an additional space for accommodating other elements of the device, in particular the pendulum damper.
    This additional space in front of the limiter allows for a compact module, compact, and performs several functions.
    The disk of the limiter may be plane, the two faces of this disk may be parallel and perpendicular to the axis of rotation.
    The surface connection may extend in a plane, preferably in a plane perpendicular to the axis of rotation.
    The surface connection can be established between the total surface of a face of the liner and the limiter disk. This connection can be made in a single manufacturing step, which advantageously makes it possible to reduce the manufacturing costs of the device.
    Alternatively the surface connection can be established only between a portion of a face of the liner and the disk of the limiter.
    Preferably, the liner is overmolded on the limiter disk to form the surface bond by adhesion.
    Alternatively, the gasket may be glued or welded to the limiter disc to form the adhesion surface bond. The absence of a rivet makes it possible to have a lining having an axial thickness which may be less than 1 mm, preferably less than 0.5 mm.
    For the limiter, such a thickness of packing is sufficient, the configurations of the device in which the lining can be made to wear being the exception.
    The lining may comprise a continuous wire wound and impregnated with a connecting matrix. Alternatively, the liner may comprise fibers added to a bonding matrix.
    The lining may have a form of annular disc of axis of rotation. Such a lining is drilled around the axis of rotation. Alternatively, the liner may take the form of a disk portion, in which case the limiter may comprise a plurality of spaced apart linings, in particular circumferentially, from each other and arranged regularly about the axis of rotation.
    Preferably, the limiter comprises at least two packings disposed on either side of the limiter disc, in particular only one packing on each side when these have an annular disk shape, in particular a plurality of packings when these have an annular disk portion shape. From one side to the other of the limiter disk, the linings may face each other in pairs or they may be staggered. The axial thickness of the assembly formed by the trim or discs of the limiter may be less than 3 mm, preferably less than 2 mm, more preferably less than 1.5 mm.
    This small thickness, especially compared to the thickness of riveted linings, provides a satisfactory available space in front of these fittings to accommodate other elements of the device, including the pendulum damper.
    This advantageously makes it possible to obtain a device for damping torsional oscillations that is more compact than those of the prior art.
    The device may include a rotary output hub about the axis of rotation. This output hub can be secured to each of the torsion damping dampers so that the pendulum damper and the additional damper are integral in rotation. Thus the pendulum damper can rotate the additional damper and vice versa.
    This output hub may be able to transmit a torque, for example, to a driven shaft. The additional damper can be centered on the output hub. The additional damper can be integral with the output hub, in particular via its output element. The output element of the additional damper is, for example, forcibly mounted on the output hub. Alternatively the output hub can be engrained by the output member of the additional damper.
    Preferably, a plurality of mechanical energy storage members is arranged between the input and output elements of the additional damper.
    The mechanical energy storage members counteract the pivoting of the output member relative to the input member.
    The mechanical energy accumulator members may be springs, in particular curved springs. The additional damper may comprise an auxiliary annular web and two guide rings, mounted on either side of the auxiliary web. The guide washers can axially maintain the accumulator organs of mechanical energy. The input element of the additional damper may be formed by the guide washers, the output member then being formed by the auxiliary web.
    Alternatively, the input member of the additional damper may be formed by the auxiliary web, the output member being then formed by the guide washers.
    In both cases, windows are formed in the auxiliary web and in the guide washers to receive the mechanical energy storage members. The pendulum damper can also be centered on the output hub. The pendulum damper may comprise a rotary pendulum support around the axis of rotation. The pendulum damper may be centered on the output hub via its output member.
    The pendular support may be rotatably connected to the output hub, for example by force fitting, for example by gearing. The pendular support may not extend radially beyond the liner. The pendular damper may comprise at least one pendular mass, preferably a plurality of pendular masses, able to move freely relative to the pendular support and guided by the same pendular support.
    The pendulum mass can be mounted at the periphery, in particular external, of the pendular support. The pendulum mass is driven in a pendulum operation and may for example comprise two parts mounted axially on either side of the pendular support and interconnected by one or more spacers each through an opening of the pendular support. A roller can cooperate with a raceway formed in each spacer and with the edge of the corresponding opening of the pendular support.
    Alternatively, the roller can cooperate with two raceways, each formed in an opening of a portion of the pendulum mass, and with a third raceway formed by the edge of an opening of the pendulum support different from the openings of the support pendular dedicated to the spacers.
    In each of these cases, several rollers may be provided for each pendulum mass.
    In each case, the axial thickness of the pendular damper at the level of the pendulum mass may be between 9 and 15mm.
    In response to torsional oscillations or rotational acyclisms, each pendulum mass moves in such a way that its center of gravity oscillates pendulum.
    Preferably, the pendulum mass and the lining are offset axially.
    When looking at the device for damping torsional oscillations along the axis of rotation, the pendulum mass can describe a zone of motion that can be superimposed at least partially with the movement zone described by the lining. The areas of movement of the lining and the pendulum mass overlap axially at least partially.
    Thus, in certain configurations of the device, there is an axis parallel to the axis of rotation passing through both the pendulum mass and the friction lining. In such cases, the lining and the pendulum mass can therefore be axially opposite one another. The assembly formed by the trim or pads and the limiter disk and the pendular mass or masses may extend according to a coinciding diameter.
    When several lining and / or pendulum masses are provided, the movement zones of each lining may coincide and the movement zones of each pendulum mass may coincide.
    When measured along an axis parallel to the axis of rotation passing through the pendulum mass and the lining, the axial thickness of the pendulum damper on the one hand and the axial thickness of the assembly formed by the one or more fittings and the limiter disk on the other hand can check a ratio between 3 and 8, preferably between 5 and 7.5. The pendular damper is thus thicker than the assembly formed by the trim or pads of the limiter on which they are attached. The axial thickness of the pendulum damper being maximum at the level of the pendulum mass, when measured along the axis of rotation, the maximum thickness of the pendular damper and the thickness of the assembly formed by the or the fittings and the limiter disc can check the same ratio as the one just above. The available space in front of the lining makes it possible to accommodate one or more pendulum masses having a satisfactory thickness. The filtration performance of the pendulum damping being in particular related to the mass of the pendular masses, the device thus makes it possible to filter the acyclisms effectively.
    The device may comprise a torque input element, in particular a flywheel integral in rotation, in particular by means of a plurality of rivets, drive discs, in particular two drive disks, concentric rotational axis and apartment at the torque limiter.
    In case of overtorque applied to the limiter, the or lining can slide relative to the drive discs.
    The two drive discs are axially spaced apart so that they frame the trim or discs of the limiter. These two drive discs can move closer to each other when one moves away from the axis of rotation to be in contact. At this contact zone, a plurality of rivets can make it possible to secure the two drive disks. These two drive discs can be fixed radially beyond the trim or seals.
    The limiter may also include a rotary drive plate about the axis of rotation and able to move axially. The training tray can be arranged to be the two training discs. The drive plate can be secured in rotation of the two drive discs.
    The trim or pads may be interposed between the drive plate and one of the drive discs.
    When the limiter has linings disposed on either side of the limiter disk, each can be supported on a face of a drive disk or on a face of the drive plate.
    In case of overtorque applied to the limiter, the packings are arranged to slide, especially in rotation, relative to the drive disc and the drive plate on which they rest.
    An elastic member, preferably a Belleville washer, may also be interposed between one of the two drive discs and the drive plate. The resilient member may be supported on the face of the drive plate opposite the face of the plate on which rests one or the linings. The elastic member makes it possible to hold the drive plate in abutment with the trim or gaskets, despite the wear of this or these gaskets. The elastic member may be prestressed so as to permanently exert a calibrated pressure force on the drive plate, allowing the pinch or the fittings between this training plate and the drive disc
    In addition or independently of what has been previously said, the pendulum damper can be arranged downstream, in the torque transmission sense, of the additional damper. The additional damper can be arranged between the limiter and the pendulum damper in the sense of torque transmission. The pendulum damper can be axially offset from the limiter. The pendulum damper can be axially offset from the additional damper. The pendulum damper can be axially framed between the input element of the device and the additional damper. The pendulum damper may be axially framed between the input element of the device, in particular the primary flywheel, and the limiter. The pendulum damper can be arranged outside the path taken by the couple.
    The limiter can be centered on the flywheel.
    The limiter may be radially beyond the additional damper. The invention also relates to a motor vehicle chain comprising a module as described above. The invention will be better understood and other details, features and advantages of the invention will become apparent on reading the following description given by way of non-limiting example with reference to the accompanying drawings, in which: FIG. 1 is a view , schematic and partial, in section, of an exemplary device for damping torsional oscillations according to the invention. - Figure 2 shows areas of movement of a friction lining and a pendulum mass.
    FIG. 1 shows a torsion oscillation damping device 1 for a motor vehicle transmission chain, comprising: - a pendulum torsion oscillator 2, - an additional torsional vibration absorber 3 , comprising an input member, an output member, both rotatable about an axis of rotation X, and a plurality of mechanical energy accumulator members arranged between the input and output members, and - a torque limiter 4 comprising at least one friction lining 5 fixed to a disk 6 integral in rotation with the input element of the additional torsional oscillation damper 3.
    In the example considered, the mechanical energy accumulator members are curved springs 9 which counteract the pivoting of the input element with respect to the output element.
    In the example considered, the additional damper 3 comprises an auxiliary annular web 10 forming the output element of the additional damper 3 and two guide rings 11 forming the input element of this damper. These two guide washers 11 are mounted on either side of the auxiliary web 10 and windows 12 are formed in the auxiliary web 10 and in the guide washers 11 to receive the springs 9. In addition, the guide washers 11 axially maintain these springs 9 so that they can not escape.
    In the example considered, the limiter 4 is radially beyond the additional damper 3 and the disc of the limiter 6, plane, is fixed to one of the guide washers 11 by a plurality of fasteners, by example of rivets.
    Two X-shaped annular disk-shaped packings 5 are disposed on either side of the limiter disk 6 (one liner on each side) and fixed on this disk in a bonding surface connection.
    Note that in the example, gaskets 5 shaped disk portion may be disposed on either side of the disk of the limiter 6 to replace the annular disk-shaped lining.
    These liners may comprise a continuous yarn wound and impregnated with a binding matrix and / or fibers added to a connecting matrix.
    In the example under consideration, the adhesion surface bond extends along a plane perpendicular to the X axis, the gaskets 5 and the limiter disk 6 having plane facing surfaces perpendicular to the X axis.
    This adhesion surface bond is established between the total surface of a face of the liner and the disk of the limiter 6. In the example under consideration, the adhesion surface bond can also be established only between a part of the face of the lining. 5 and the limiter disk 6.
    In the example under consideration, the linings 5 are overmolded on the disk of the limiter 6 to form the surface bond by adhesion. Note that the gaskets 5 can also be welded or glued.
    In the example considered, the gaskets 5 each have an axial thickness of less than 1 mm, preferably less than 0.5 mm, and the axial thickness of the assembly formed by the gaskets 5 and the limiter disk 6 is less than 3 mm, preferably less than 2mm, more preferably less than 1.5mm.
    The limiter 4 comprises two concentric drive disks X axis, integral with each other, and a drive plate 16 rotatable about the axis X, able to move axially, arranged between the two drive discs 15 and integral in rotation of these two discs.
    The gaskets 5 are interposed between the drive plate 16 and one of the drive discs 15 so that they rest permanently on one face of the drive disk 15 and on one face of the drive plate 16.
    In case of overtorque applied to the limiter 4, the packings 5 are arranged to slide in rotation relative to the drive disk 15 and the drive plate 16 on which they rest.
    In the example considered, an elastic member, here a Belleville washer 18, is interposed between the other of the two drive discs 15 and the drive plate 16, the Belleville washer 18 is therefore resting on the face of the plateau drive 16 opposite to the face of this plate on which the liner 5 rests. This Belleville washer 18 makes it possible to hold the drive plate 16 in abutment with the linings 15, despite the wear of these linings 5. The Belleville washer 18 is prestressed in such a way as to permanently exert a calibrated pressure force on the drive plate 16 allowing pinching of the linings 5 between this drive plate 16 and the drive disc 15.
    In the example under consideration, the assembly formed by the linings 5 and the disk of the limiter 6 on which they are overmoulded is arranged to be able to slide in rotation with respect to the drive discs 15 and the drive plate 16 in the event of overtorque applied to the limiter 4.
    The two drive discs 15 thus frame the packings 5 and the disc of the limiter 6 and when one moves away from the X axis these two drive discs 15 come closer to each other until be in touch. At this contact zone, a plurality of rivets 20 makes it possible to secure the two drive discs 15.
    The two drive disks 15 are thus secured radially beyond the lining 5 and radially at the same level, these two disks are secured in rotation to a torque input element of the device 1. In the example considered, the Torque input member is a flywheel 21 formed in several distinct parts.
    In the example considered, the flywheel 21 is intended to be fixed on a driving shaft such as a crankshaft of an internal combustion engine.
    In the example considered, the torque is transmitted from the flywheel 21 to the limiter 4 and to the additional damper 3, the auxiliary web 10 forming the output member is integral with an output hub of the device 23 by mounting by force.
    This output hub 23, rotatable about the X axis, is able to transmit a torque, for example, to a driven shaft not shown here.
    In the example considered, the additional damper 3 is centered on the output hub 23 via the auxiliary web 10.
    Furthermore, the pendulum damper 2 comprises a rotatable support 25 rotatable about the X axis and a plurality of pendulum masses 26. This pendulum damper 2 is centered and integral with the output hub 23 via the pendular support 25.
    The pendular support 25, which does not extend radially beyond the lining 5, is integral and centered on the output hub 23 by force fitting. The pendular support 25 is formed of a single piece and rigid. The pendulum support 25 is devoid of any part having a remarkable elasticity.
    The pendulum masses 26, mounted at the periphery of the pendular support 25, are able to move freely relative to this support while being guided by it.
    The pendular masses 26 are each driven in a pendulum operation and have two parts 27 mounted axially on either side of the pendular support 25 and interconnected by two spacers each through an opening of the pendular support 25. A roller 29 cooperates with two raceways, each formed in an opening 30 of a portion 27 of the pendulum mass 26, and with a third raceway formed by the edge of an opening 31 of the pendular support 25 different from the openings of the pendular support dedicated to spacers.
    In response to torsional oscillations or rotational acyclisms, each pendulum mass 26 moves so that its center of gravity oscillates pendulum.
    In the example considered, the axial thickness 36 of the pendular damper 2 at the level of the pendular masses 26 is between 9 and 15mm.
    In the example considered, the swinging damper 2 is axially offset from the additional damper 3 and the limiter 4. Furthermore, this swinging damper 2 is outside the path taken by the couple. Indeed, the torque would always be transmitted by the device 1 in the absence of the pendulum damper 2.
    In the example considered, the additional damper 3 is disposed between the limiter 4 and the swinging damper 2 in the torque transmission sense.
    In the example considered, the pendulum masses 26 and the liners 5 are axially offset and they overlap at least partially when viewing the device 1 along the X axis.
    It is possible to observe this overlap in FIG. 2 which represents zones of movement respectively of the gaskets 5 and the pendulum masses 26.
    The movement zones of the pendular masses 26 or the gaskets 5 are the set of positions occupied by these pendular masses and these gaskets.
    The pendulum masses 26 all describe the same movement zone 32, this zone of movement is superimposed axially and partially with the movement zone 33 described by the linings 5. In certain configurations of the device 1, there is at least one axis parallel to the X axis traversing both a liner 5 and a pendulum mass 26.
    In the example considered and with reference to FIG. 1, when measured along an axis parallel to the X axis traversing both a pendular mass 26 and a lining 5, the axial thickness 36 of the pendulum damper 2 of FIG. one part and the axial thickness 35 of the assembly formed by the linings 5 and the disk of the limiter 6 on the other hand satisfy a ratio of between 3 and 8, preferably between 5 and 7.5. The invention is not limited to the examples which have just been described.
