Description

DESCRIPTION

Title of the invention: Pendulum damping device and Method of manufacturing such a device

[1] The present invention relates to pendular damping devices, in particular for a clutch of a transmission system, such as used for example in the automotive field. The invention also relates to a method of manufacturing such a pendulum damping device.

[2] Such a pendulum damping device is conventionally used to filter the vibrations due to the acyclisms of the engine of a motor vehicle, the frequency of the acyclisms varying in particular as a function of the number of cylinders in operation and the speed of rotation of the engine. . In known manner, the pendulum damping device comprises an annular support intended to be driven in rotation, and one or more pendular bodies, mounted to oscillate on the support about an axis parallel to the axis of rotation of the support.

[3] A pendulum body is conventionally formed by a pair of oscillating masses, sandwiching the support and rigidly integral with one another, generally by means of a connecting member extending through a window formed in the support and cutouts made in the oscillating masses provided for this purpose. The movement of a pendulum body relative to the support is generally guided by two rolling members each cooperating with a support rolling track and a pendulum body rolling track. The bearing tracks of the support and pendulum body extend so that in use the running gear is in centrifugal and centripetal support, respectively, on said tracks.

[4] Each specific engine of order n, includes different criteria based on their filtration capacity, size, free space, positioning on the transmission system, number of cylinders, etc. provide pendular damping devices of orders n which are different and able to adapt to the same small footprint.

[5] These elements of the pendulum bodies of different n orders are therefore differently designed in order to be specifically tuned according to the number of cylinders in the engine, which imposes complex manufacturing operations, as well as an additional cost.

[6] It was also found that, during the stages of manufacture and assembly of pendulum damping devices of different orders, the parts produced from the same range (oscillating mass, running gear, linkage) and suitable for different orders were mixed. This distinction between pieces of n, different orders of the same range is hardly perceptible to the human eye.

[7] These sources of errors on production lines generate assembly problems, detection of erroneous parts, non-compliance, as well as a production delay and an increase in the scrap rate. Current solutions are not entirely satisfactory. There is a need to standardize the parts in production as much as possible. [8] To this end, the invention proposes, according to a first aspect, a method of manufacturing a pendulum damping device suitable for filtering a first order n1 of pendulum damping, comprising the following steps: a. Provide X axis support; b. Provide at least one independent oscillating mass of the first order n1; vs. Cut in the support at least one support rolling track suitable for the first order n1; d. Provide an independent first order n1 running gear and a connecting member adapted to the first order n1; or. Provide an independent first order n1 connecting member and a running gear adapted to the first order n1; e. Fit the independent first order n1 running gear and the n1 first order matched connecting gear, or the n1 first order independent connecting gear and a n1 first order matched rolling gear, with the independent oscillating weight of the first order n1 within the blank of the support;

[9] An independent first order oscillating mass n1 can also be defined as a “standard” oscillating mass. The so-called standard oscillating weight is in particular of identical shape and size regardless of the n order of the device.

[10] An independent first order n1 running gear can also be defined as a “standard” running gear. The so-called standard running gear is in particular of identical shape and dimension regardless of the n order of the device. The link member suitable for order n1 is chosen in particular from a range of link members suitable for different orders. Each connecting member is in particular adapted to a specific order.

[11] Alternatively, an independent first order link member n1 can also be defined as a “standard” link member. The so-called standard connecting member is in particular of identical shape and dimension whatever the n order of the device.

The running gear suitable for order n1 is chosen in particular from a range of running gear suitable for different orders. Each running gear is in particular adapted to a specific order.

[12] In the context of the request, the expressions “independent of the first order n1” and “standard” are used in particular in an equivalent manner.

[13] This manufacturing process, according to the first aspect of the invention, has the advantage of standardizing as much as possible the production of pendulum damping devices with different n order requirements. Such a manufacturing process makes it possible to provide certain same so-called “standard” parts, during the manufacture of various pendulum damping devices, and this independently of their order linked to the engine and of the number of cylinders in operation. Thus, the manufacturing steps are simplified.

[14] By “standard” part, we can define an independent component of order n ,. Any component "independent of the order n," is designed in opposition to the order n, of the motor. In in other words, certain parts of the pendulum damping device no longer need to be tuned specifically according to the number of cylinders of the engine.

[15] By "standard" part, we mean any part designed in opposition to the order n of the engine, that is to say standardized or equal parts, in other words parts of identical shapes and dimensions whatever the length. order of the final device, and which adapt to the other “non-standard” parts of the device. The differences in the same range of parts are eliminated, for "standard" oscillating masses, for running gear

"Standards" or for the "standard" liaison bodies. In other words, for any order n, of a device, i.e. order value n, of a device, we will systematically use these only so-called "standard" parts.

[16] By "non-standard" or "adapted to a specific order" part, conversely, we mean any part specifically designed and adapted to be granted to the required order of the engine. For example, for a part suitable for order n1, its specific characteristics (shapes, predetermined dimensions, etc.) are modified to meet the requirements of said engine.

[17] In the context of the application, the expression "non-standard" can thus be used instead of "suitable for order n1 or n2" or "suitable for different orders".

[18] In the context of the application, by "order n," is meant for a pendulum damping device a value of tuning order n, main, which is defined according to the number of cylinders of the engine. The pendulum damping device thus filters the vibrations at order n, for which the vibrations generated by the acyclisms of the motor are the greatest.

[19] According to step b, therefore, only one type or reference of "standard" oscillating weight is supplied for any of the n orders required by the engine. According to this method, the manufacturing steps of such an oscillating weight are simplified by using a single range of tools.

[20] Also, depending on step d or d, only one type of "standard" running gear or linkage is provided for any of the n orders required by the engine. According to this method, the manufacturing steps of such a rolling or connecting member are simplified by using a single range of tools. Finally, only the parts granted to order n1 (“non-standard”) are chosen to complete the assembly on a specific engine of order n ,, said non-standard parts adapted to order n1 allowing the specific tuning of the order n1. device according to the order n1 required by the engine, so as to finalize said device.

[21] By standardizing the manufacture of these parts regardless of the pendulum damping device to be manufactured, the handling and assembly steps are simplified. Confusion is avoided, manufacturing errors and rejects are reduced. The overall production costs and times of such resulting damping devices are also reduced.

[22] The invention also proposes, according to a second aspect, a method of manufacturing a pendulum damping device adapted to filter a first order n1 of pendulum damping, comprising the following steps: a. Provide X axis support; b. Provide at least one independent oscillating mass of the first order n1; vs. Cut in the support at least one support rolling track suitable for the first order n1; d. Provide an independent running member of the first order n1 and a connecting member adapted to the first order n1, the connecting member being chosen from a range of connecting members adapted to different orders; e. Fit the independent first order running gear n1 and the connecting member adapted to the first order n1, with the independent first order oscillating weight n1 within the cutout of the support;

[23] This manufacturing process, according to the second aspect of the invention, has the advantage of providing a single type of "standard" running gear, identical and opposite to the order n1. That is, of the same shape and identical dimensions, regardless of the first order n1 required by the engine. This method therefore makes it possible to reduce the costs, errors and manufacturing time of the connecting members of each pendulum damping device, by using a single range of tools.

[24] According to a third aspect, the invention proposes a method of manufacturing a pendulum damping device adapted to filter a first order n1 of pendulum damping, comprising the following steps: a. Provide X axis support; b. Provide at least one independent oscillating mass of the first order n1; vs. Cut in the support at least one support rolling track suitable for the first order n1; d. Provide an independent first order n1 link and a suitable first order n1 running gear, the running gear being chosen from a range of running gear suitable for different orders; e. Mount the independent first order n1 link member and a suitable first order n1 rolling member, with the independent first order n1 oscillating weight within the cutout of the support;

[25] This manufacturing process, according to the third aspect of the invention, has the advantage of providing a single type of "standard" linkage, identical and opposite to the order n1. That is, of the same shape and identical dimensions, regardless of the first order n1 required by the engine. This method therefore makes it possible to reduce the costs, errors and manufacturing time of the connecting members of each pendulum damping device, by using a single range of tools.

[26] The first, second and third aspects of the invention may exhibit any of the characteristics described below taken independently of each other:

[27] - Advantageously, the connecting member is force-fitted into the standard oscillating weight during the assembly step; [28] - Alternatively, the connecting member is riveted with the standard oscillating weight during the assembly step. This solution is particularly effective for riveted connecting members because these riveted connections consume a lot of space;

[29] - Advantageously, the connecting members adapted to different orders n, (“non-standard”), can comprise:

- at least one manufacturing step common to all models of connecting members in the range, forming a semi-finished metal part, in particular by cutting and forming a sheet in a press,

- at least one differentiation step, including in particular the machining of the contour to be adapted to a specific order, for example to the first order n1;

[30] The at least one common manufacturing step can be the formation of the inner periphery identical to all the links.

[31] The at least one differentiating step can be the machining of an outer periphery forming part of the contour of the struts, so as to adapt it to that of a specific order.

[32] - Advantageously, the running gear adapted to different orders n can include:

- at least one manufacturing step common to all models of running gear in said range, forming a semi-finished metal part according to a predefined diameter, by cutting and forming a sheet in a press,

[33] The at least one common manufacturing step can be the formation of an initial metal part with a constant thickness or length "L".

[34] Advantageously, the initial metal part can comprise a predefined radius R or predefined diameter. The predefined radius "R" or the default predefined diameter of the initial common metal part can be sized in order n, the highest in the range (order of the engine including the largest number of cylinders). In other words, the other specific radii or diameters of the other remaining “non-standard” rolling members are logically smaller than said predefined radius or predefined diameter by default.

[35] The at least one differentiating step can be the machining of the running surface of the running gear, adjusting and reducing it to the radius suited to a specific order;

[75] Other features and advantages of the invention will become apparent on reading the following description and on examining the appended drawing in which:

- [Fig. 1] shows a partial view of a torsional oscillation damping device according to a second embodiment of the invention;

- [Fig. 2] shows, in perspective, a “standard” connecting member of the device of [FIG. 1];

- [Fig. 3] shows a partial front view of a torsional oscillation damping device according to a first embodiment;

- [Fig. 4] shows, in perspective, different possible forms of a "non-standard" connecting member according to the device of [Fig. 3];

- [Fig. 5] shows, in perspective, a “standard” rolling member of the device of [FIG. 3];

- [Fig. 6] shows a view similar to [FIG. 3] but with an alternative embodiment of the connecting member;

[76] In the various figures, identical references are used to designate identical or similar members. In particular, all of the variants and all of the embodiments described can be combined with one another if there is nothing to prevent this combination from a technical point of view.

[77] By "centrifugal support" is meant a support force comprising a component oriented away from the X axis of rotation. Unless otherwise indicated, "axially" means

"Parallel to the axis of rotation X of the support"; “Radially” means “along a transverse axis intersecting the axis of rotation of the support”; “Angularly” or “circumferentially” means “around the axis of rotation of the support”.

[78] By "vehicle" is meant motor vehicles, which include not only passenger vehicles, but also industrial vehicles, which includes in particular heavy goods vehicles, public transport vehicles or agricultural vehicles, but also any transport device enabling a living being and / or an object to pass from one point to another. [79] The term “pendulum body” is understood to mean an oscillating mass which is mounted so as to oscillate on the support in response to the acyclisms of the engine of order n, (n1, n2, n3, etc.) of the vehicle. A pendulum body is conventionally constituted by a pair of oscillating masses, or “pendular masses”, extending so as to sandwich the support and rigidly integral with one another. A pendulum body further comprises at least one connecting member, also called a spacer, adapted to pair the pair of oscillating masses with one another. A pendulum body can also be formed by a single oscillating mass. The single oscillating weight can be sandwiched between two supports.

[80] By "braking" is meant the action of friction opposing a movement without blocking it completely. Two parts are said to be "rigidly joined" or "paired" when they are permanently immobilized in relation to each other. This immobilization may result from fixing the first part to the second part directly or through one or more intermediate parts. The rest position of the device is that in which the pendulum bodies are subjected to a centrifugal force, but not to torsional oscillations originating from the acyclisms of the motor of order n ,.

[81] Pendulum bodies are said to be "supported by centrifugal force" when the rotational speed of the support is sufficient to keep the pendulum bodies pressed radially outwardly against the running gear, and through them against the support. Unless otherwise indicated, the verbs "comprise", "present" or "understand" should be interpreted broadly, that is to say without limitation. The thickness is measured along the X axis of rotation.

[82] A torsional oscillation damper device 10, partially shown in FIGURE 3 according to a first embodiment of the invention, comprises at least a first pendulum damping device 1. The first pendulum damping device 1, in particular suitable for equipping a transmission system, here in a motor vehicle, is for example integrated into a component of such a transmission system.

[83] This component being, for example, a double damping flywheel, or a flywheel integral with the crankshaft, a double clutch, or a clutch friction disc. This component may form part of a power train of a motor vehicle, the latter possibly comprising a heat engine or even a combustion and explosion engine, the engine having a predetermined number of cylinders, for example three, four or six cylinders, whose acyclisms define one or more orders n1, n2, etc ... required for the first device 1 of said damping device 10.

[84] A high order n comprises a large number of cylinders in operation of the engine. Conversely, a low n order has a low number of cylinders operating the engine.

[85] In the examples illustrated, the first device 1 is adapted to filter a first order n1 of pendular damping. The second device 2 is adapted to filter a second order n2 of pendular damping. The second order n2 is different from the first order n1. For example, the second order n2 can be adapted to a higher number of cylinders in operation of the engine than that of the first order n1. [86] To be tuned to the desired pendular damping order, the first device 1 can include at least one "non-standard" part differently designed to be adapted to the target order, for example n1. This in order to specifically adapt said device to a different number of cylinders in operation of the engine.

[87] The first device 1 can also include identical parts called

"Standards", designed without influence of the target order n1 of the engine. Thus, whatever the targeted order of the device to be manufactured, these only so-called "standard" parts are systematically used. The various standard and non-standard parts will be explained in the remainder of the description.

[88] The first pendulum damping device 1 comprises at least one pendulum body 13 which is mounted on a support 12. The first device 1 preferably comprises a plurality of pendulum bodies 13 mounted on the support 12.

[89] Each pendulum body 13 of the first device 1 comprises at least one oscillating mass 14. Each pendulum body 13 comprises at least one connecting member 20 matching the at least one oscillating mass 14 through a window 15 of support 12.

[90] In the examples illustrated, each pendulum body 13 can comprise two oscillating masses 14 which are paired by means of at least one connecting member commonly called a "spacer" 20. In FIGURES 1 and 3, each pendulum body 13 comprises two spacers 20. Conversely, at least one pendulum body 13 illustrated in FIGURE 6 may include a single spacer 20.

[91] Each spacer 20 can be riveted respectively to the oscillating masses 14. Alternatively, each spacer 20 can be force-fitted respectively into the oscillating masses 14, illustrated in particular in FIGURE 1.

[92] Generally, each strut 20 may include a main body which extends radially and circumferentially, and is generally arcuate in shape.

[93] The main body extends radially between a radially outer upper face called "outer periphery" 22 and a radially inner lower face called "inner periphery" 21.

[94] Each main body extends circumferentially between a first circumferential end 23 and a second circumferential end 24.

[95] The inner periphery 21 is located radially as close as possible to the X axis and it may extend angularly between the two opposite circumferential ends 23 and 24. The inner periphery 21 can cooperate respectively with an inner edge of the window

15. The inner periphery 21 may be concave in shape.

[96] The outer periphery 22 is located radially furthest from the X axis and may extend angularly between the two opposite circumferential ends 23 and 24. The outer periphery 22 may be concave in shape.

[97] The spacer 20 may be "non-standard". It is then adapted to the order n1 of said first device 1. Consequently, the spacer 20 can be cut specifically according to the order n1 of the first device 1. [98] Each oscillating mass 14 comprises a main body which extends radially and circumferentially, and is generally arcuate in shape. The main body extends radially between radially inner 6i and radially outer 6th edges of the oscillating mass 14. The main body extends circumferentially between a first circumferential end 141 and a second circumferential end 142. The oscillating masses 14 of the first device 1 may be located on either side of the support 12 and are axially facing each other.

[99] Alternatively, each pendulum body 13 comprises a single oscillating weight 14 and two supports 12. In such a situation, the two supports 12 of the first device 1 can be matched by means of at least one connecting member such as a riveting positioned radially inwardly with respect to the pendulum body (s). Thus, the two supports 12 can be axially facing each other. Consequently, the oscillating mass 14 is located respectively between the two supports 12.

[100] Two covers can then be positioned axially around the assembly formed by the two supports and the pendulum bodies. In this situation we can thus find successively axially for the first device 1: one of the covers, one of the supports 12, the oscillating weight 14, the other of the supports 12, and the other of the covers.

[101] Advantageously, the support 12 can be an input element of the torsion damper, an output element or an intermediate phasing element arranged between two series of spring of the damper, or an element connected in rotation to one of the aforementioned elements and distinct from the latter, then being for example a support specific to said first device 1.

[102] The support 12 of said first pendulum damping device 1 can then be one of a component guide washer, a component phasing washer, or a separate support for said web, said guide washer and said phasing washer. In the case where the device is integrated into a flywheel integral with the crankshaft, the support may be integral with this flywheel.

[103] The support 12 can still be other, such as a flange.

[104] In the examples considered, the support 12 has the overall shape of a ring formed by a cut metal sheet, generally steel, with a thickness typically less than 10 mm (millimeters), preferably less than 9 mm, of preferably less than 8 mm.

[105] The support 12 extends axially between two opposite side faces 16. The two side faces 16 can be flat. The two side faces 16 may extend between a radially inner edge and a radially outer edge. The radially inner edge may conventionally be circular in shape.

[106] At least one window 15 passes through the support 12 depending on its thickness. Each of the windows 15 defines an empty space inside said support 12. Preferably, as many windows 15 as there are pendulum bodies 13 pass through the support 12. Each spacer 20 can pass through a window 15 of the support 12. Each spacer 20 can be respectively fully received in the thickness of said window 15. Advantageously, at least part of the parts of each pendulum body 13, 13 ′ can be “standardized” for equip several different orders of devices. Consequently, the “standard” part (s), that is to say here of identical design, can equip various pendulum damping devices, independently of their target order n. In addition, a standard part necessarily cooperates with one or more non-standard parts.

[107] In the illustrated examples of the first embodiment, at least one oscillating weight 14 can be independent of order n1, ie "standardized". Its shape and dimensions are the same regardless of the first device and the order n1 targeted by the latter. The at least one oscillating weight 14 can then be “standardized”, that is to say designed without influence of the value of the targeted order n1 or else independently formed with respect to the value of the targeted order n1 of the target. first device.

[108] In such a situation, the design of the standard oscillating masses 14 may be identical. Said oscillating masses 14 will therefore always have the same shapes

"Standard" and the same "standard" dimensions regardless of the order n1 required of the motor (adaptable to several values of orders n, different ...).

[109] The first device 1 further comprises at least one running member 40 which is independent of the order n1 of the first device 1, called "standard" running member 40. The standard running gear 40 is independent of the order n1 of the first device 1, ie of identical shape and dimensions regardless of the order n ,.

[110] The rolling member 40 is, for example, a roller. Alternatively, the running gear can be a ball or a ball bearing. In a variant not shown, a pendulum body 13 can be mounted oscillating on the support 12, for example by means of a single rolling member 40.

[111] Alternatively, each pendulum body 13 is mounted oscillating on the support 12 by means of two rolling members 40, as illustrated for example in FIGURE 6. The two rolling members 40 can pass through a single window 15 of the support 12 and guide the movement of the oscillating weight (s) 14, of a pendulum body 13 relative to the support 12.

[112] In general, the rolling member 40 defines two side faces 44 which are substantially transverse. The two side faces 44 of the rolling element 40 can extend radially between the rolling surface 43 facing the oscillating masses 14. The two side faces 44 of the rolling element 40 can have a domed shape.

[113] Each rolling member 40 can advantageously pass through a window 15 of the support and guide the movement of the oscillating weight (s) 14 relative to the support 12. In the examples considered, each rolling member 40 can run on a rolling track. support 41 integral with the support 12 when the pendulum body 13 is supported by centrifugal force. The curvature of the support raceway 41 may be convex.

[114] Each rolling member 40 can roll on a pendulum body rolling track 42 integral with the pendulum body 13, when the pendulum body 13 is supported by centrifugal force. The pendulum body rolling track 42 may have a concave shape. That is, the curvature of the pendulum body raceway 42 may be in a direction opposite to the curvature of the support raceway 41.

[115] More specifically, each rolling member 40 of the first device 1 can successively comprise axially:

- a portion disposed in an opening of one of the first oscillating masses 14 and cooperating with the first pendulum body rolling track 42 formed by part of the outline of this opening,

a portion disposed in the window 15 of the support 12 and cooperating with a first support rolling track 41 formed by a part of the outline of this window 15, and

- A portion disposed in an opening of the other first oscillating weight 14 and cooperating with the first pendulum body rolling track 42 formed by part of the outline of this opening.

[116] At least a part of the window 15 may form a support rolling track 41. The window 15, and subsequently the support rolling track 41, can be cut inside the support 12. The windows 15 can be cut out inside the support 12. The windows 15 can be regularly distributed over the entire circumference respectively of the support 12.

[117] More precisely, the edges of the windows 15, in particular the radially outer parts of said edges, can define the first support rolling tracks 41.

[118] As a variant, the spacer 20 of the first device 1 can form the first pendulum body rolling track 42 or the first pendulum body rolling tracks 42 when two rolling members 40 are in the same window 15. So more precisely, the outer periphery 22 of the spacer 20 can form the track (s) of the pendulum body 42.

[119] The support runway 41 can be “non-standard”. It is adapted to order n1 of said first device 1. Therefore, the support rolling track 41 can be cut specifically according to the order n1 of the first device 1 with which it cooperates. Subsequently, at least part of the windows 15 can be adapted to order n1 of said first device 1.

[120] In general, the shape of the support 41 and pendulum body 42 rolling tracks may be such that each pendulum body 13 is moved relative to the support 12 at the same time: in translation around a fictitious axis parallel to the axis of rotation X of the support 12 and, also in rotation around the center of gravity of said pendulum body 13, such a movement also being called “combined movement” and disclosed for example in application DE 102011 086 532.

[121] As a variant, the shape of the aforementioned support 41 and pendulum body 42 rolling tracks may be such that each pendulum body 13 is only moved relative to the support 12 in translation around a fictitious axis parallel to the axis. X of support rotation 12.

[122] Each rolling member 40 can be freely mounted in a window 15 of the support 12. Each rolling member 40 can have a running surface 43 adapted to be at least partially in contact with the support rolling track 41 and the pendulum body rolling track 42 respectively.

[123] Each rolling member 40 can be a cylinder of constant radius “R”. Each rolling member 40 can be blind. Each rolling member 40 can pass through.

[124] Each rolling member 40 can only be stressed in compression between the pendulum body rolling track 42 and the support rolling track 41. The pendulum body rolling track 42 and the support rolling track 41 cooperating with the same rolling member 40 may be at least partially radially facing each other, that is to say that there are planes perpendicular to the X axis of rotation in which these rolling tracks both extend.

[125] Each rolling member 40 can cooperate with the pendulum body rolling track 42 and with the support rolling track 41 only via its outer rolling surface 43.

[126] Roll 40 can be "standardized" to fit several different orders of devices. Consequently, the “standard” design of the running elements or rollers 40 is identical. That is, they have the same "standard" shapes and dimensions regardless of the value of the n1 order required of the engine. In FIGURES 3, 4 and 6, the rolling surface 43 of the rollers may be the same, the advantage is to improve the stages of manufacture of such rolling elements independently of the ordering needs of the engine.

In the examples considered, the pendular bodies 13 are preferably distributed equangularly around the axis X. Preferably, their number is equal to two. Their number may be less than four. All the pendular bodies 13 can succeed one another circumferentially. The device 1, 2 can thus comprise a plurality of planes perpendicular to the axis X of rotation in each of which all the pendulum bodies 13 are arranged.

[127] Advantageously, all of the pendulum body rolling tracks 42 can have exactly the same shape between them.

[128] In the first embodiment, at least part of the parts of the pendulum body can be "non-standard". There is shown in FIGURES 3 to 4 various shapes and dimensions of models of "non-standard" spacers 20 constituting a range of n-order spacers, adapted to different order values, for example n1, n2 and n3. .

[129] The order value of n1 is different from the order value of n2. The order value of n1 is different from the order value of n3. The order value of n3 is different from the order value of n2. The pendulum body raceways 42 of the "non-standard" spacers 20 are shown in solid or dotted lines. Each of these pendulum body raceways 42 is suitable for filtration of a separate order value.

[130] In particular, three types or models of different "non-standard" spacers 20 are illustrated in FIGURES 3 and 4, respectively adapted to three orders n1, n2, n3 different from each other. It is specified here that the rollers 40 can be “standard”. [131] The outer periphery 22 of the spacer 20 may be non-standard. Each inner periphery 21 can be standard. Therefore, the outer 22 and inner 21 peripheries are of different design from one another.

[132] Specifically, the pendulum body rolling track 42 of the spacer 20, adapted to the order n3 higher than the others (having a greater number of cylinders in operation than the orders n1 or n2), has a closed type curvature, thinner or narrower, compared to the rolling tracks of pendulum bodies suitable for other orders n1 and n2. Such a non-standard closed curvature has the advantage of faster roller movement. This bearing track of the “non-standard” pendulum body of the device can be formed and adapted only according to this order n3.

[133] Specifically, the pendulum body rolling track 42 of the spacer 20, adapted to the order n1 lower than the others, has an open type curvature, more flattened or widened, compared to the tracks of pendulum body bearings suitable for other n2 and n3 orders. Such a non-standard open curvature has the advantage of slower roller movement. This bearing track of the “non-standard” pendulum body of the device can be formed and adapted only in this order n1.

[134] In general, these different forms of curvature of the spacers are visible from the given observation point, located for example on the X axis of rotation, obviously according to an arbitrary interval sufficiently close to observe and identify the given model. spacer.

[135] Advantageously, each spacer 20 is distinguished from other models of order n, different by a specific sequence of circumferential end profiles 23 and 24, which can also be an identifying element of the given spacer model. Such design differences between outer peripheries, and consecutively between bearing tracks of the pendulum body 13, do not allow the spacers 20 to be adapted to a different order of pendular damping than theirs, during assembly on the device and its vehicle operation.

[136] As a reminder, the inner periphery 21 may conversely be of identical shape and dimensions for any of the spacers 20. The different spacers 20 in the range can have an identical number "I" of standard contact points. 211, 212, 213, 214 formed independently of the order n1.

[137] Said standard contact points can be distributed over said inner contour or periphery of each spacer. This "I" number is between two and six "standard" contact points.

[138] The standard contact points 211, 212, 213, 214 can be arranged on either side of the spacer, on its standard internal periphery 21, preferably they are arranged symmetrically with respect to an axis S passing through the middle of the spacer and / or intersecting the X axis of rotation of the support.

[139] The first device 1 further comprises at least one stop damping system 50. The stop damping system 50 can be made of an elastic material, for example an elastomer or rubber. Elastic properties presented by the stop damping system 50 can allow the damping of shocks related to the coming into contact of the pendulum body 13 and the support 12.

[140] The abovementioned stop damping system 50 can then dampen all the abutment positions against the support 12 of the pendulum body 13.

[141] The stop damping system 50 is suitable for damping the coming into stop position against the support 12 of the pendulum body 13 during the radial fall and / or the saturation of the latter of said pendulum body 13. The system stop damping 50 can be further adapted to cushion the coming into the stop position against the support 12 of the pendulum body 13 when the latter moves from the rest position in the counterclockwise direction and to cushion the coming into the stop position against the support 12 of the pendulum body 13 when the latter moves from the rest position in the non-trigonometric direction.

[142] Alternatively, the stop damping system 50 can be formed from a single piece or body extending circumferentially, and disposed radially under one of the elements constituting the pendulum body 13.

[143] The stop damping system 50 can be rigidly secured to the connecting member 20. The stop damping system 50 can be directly rigidly secured to the connecting member 20. Alternatively, the system of stop damping 50 may be rigidly integral with the connecting member 20 by means of a third element. More particularly, each stop damping system 50 can be rigidly secured to a single connecting member or spacer 20. Each stop damping system 50 can be rigidly secured to the underside of a single connecting member or spacer 20.

[144] The stop damping system 50 of the first device 1 may include two stop elements arranged on either side of the spacer. Preferably, a stop element is arranged between two immediately adjacent standard contact points 211, 212, 213, 214.

[145] In the examples illustrated, the stop elements can be "standard", and consequently the stop cushioning systems can be "standard".

[146] More specifically, the standard oscillating weight 14 can include specific housings adapted to said “standard” stop elements. Specific accommodations can be standard. The center of gravity of the stopper damping system 50 or the center of gravity of the stopper elements can, by nature, move relative to the oscillating mass 14 while being integral with the latter when the pendulum body 13 is in position. oscillation. Thus, the pendulum body 13 can further comprise standard stop elements, which further promotes the reduction of manufacturing costs without reducing the quality of filtration or increasing the noise.

[147] Alternatively, the stop damping system 50 can be rigidly secured to an oscillating mass 14. The stop damping system 50 can be directly rigidly secured to an oscillating mass 14. The damping system of stop 50 may be rigidly secured to an oscillating mass 14 via a third element. More particularly, each stop damping system 50 can be rigidly secured to a single oscillating mass 14. Each stop damping system 50 can be rigidly secured to the radially inner edge 6i of a single oscillating mass 14.

[148] The torsional oscillation damping device 10 of the first embodiment may further include a second pendulum damping device 2.

[149] The second device 2 is identical to the first device 1 except that:

- The support running tracks 41 ’formed in the openings 15’ of the second support 12 ’of the second device 2 are adapted to an order n2 different from the order n1 of the first device 1;

- The pendulum body rolling tracks 42 ’formed on the second spacers 20’ of the second device 2 are adapted to an order n2 different from the order n1 of the first device 1;

[150] Thus, the rollers 40 of the first device 1 can be identical to the rollers 40 ’of the second device 2. Thus the pendulum body of the first device is identical to the pendulum body of the second device. The spacers 20 of the first device 1 may be different from the spacers 20 ’of the second device 2.

[151] Logically, the oscillating masses 14, 14 "" standard "of the first and second devices 1, 2 are of identical shape and dimensions.

[152] The first and second supports 12, 12 'can form one and the same part, of one-piece shape and common to the devices 1, 2. Alternatively, the first and second supports 12, 12' can be separate from one of the 'other, and located for example both at two separate locations of the vehicle transmission system.

[153] The invention also relates to a second embodiment shown in FIGURES 1 and 2. The second embodiment incorporates all the characteristics of the first embodiment with the exception of the following elements:

- The spacers 20B can be “standard”. Each spacers 20B includes a pendulum bearing raceway 42B independent of the value of order n1.

- The rollers 40B can be "non-standard", as illustrated in the example of FIGURE 1. The convex shape of the rolling surface 43B of the roller 40B is only suitable according to the order n1 of the first device 1.

[154] In the case of “non-standard” rollers, the different non-standard cylinders can be of different radius, so as to define different rollers. Therefore, the running surfaces 43B can be of different contours from each other.

[155] Advantageously, the length "L" of said rolls is identical, in other words of constant dimension whatever the order to be adapted on the roll (step or common characteristic for the range of rollers). [156] When the torsional oscillation damping device 10 of the second embodiment further comprises a second pendulum damping device 2, the rollers 40B of the first device 1 may be different from the rollers 40B of the second device 2. The spacers 20B of the first device 1 can be identical to the spacers 20B of the second device 2.

[157] We will now describe the manufacturing process of the first pendulum damping device 1 of order n1 according to the first embodiment of the invention.

Manufacturing includes, among other things, the following steps:

- In a first step, we provide an X axis support 12;

- According to a second step, at least one standard oscillating mass 14 is provided, that is to say an oscillating mass 14 of predefined shape and which is independent of the order n1 of said device;

- In a third step, is cut in said support 12 at least one support rolling track 41 adapted to the targeted order n1 of said device;

- In a fourth step, we provide a connecting member 20 adapted to the targeted order n1 of said device. Said connecting member 20 is chosen from a range of connecting members suitable for different orders. A standard rolling member 40 is also provided, that is to say a rolling member of predefined shape and which is independent of the order n1 of said device;

- In a fifth step, we mount the standard rolling member 40 and the connecting member 20 adapted to the targeted order n1, with the standard oscillating weight 14 within the cutout 15 of the support 12.

[158] This method of manufacturing the second pendulum damping device 2 of order n2 is identical to the manufacturing process of the first pendulum damping device 1 of order n1 except that the elements are adapted to an order. to order n2.

[159] Advantageously, the “non-standard” spacers adapted to different orders ni, comprise at least one manufacturing step common to all the models of connecting members in the range, followed by one or more differentiation steps. .

[160] The at least one common manufacturing step may include forming a semi-finished metal part, specifically cutting and forming a sheet in a press. The at least one common manufacturing step can be the formation of the inner periphery identical to all the connecting members. In other words, we can cut with the same tool all the "standard" shapes of the connecting members, that is to say all the shapes other than the outer periphery adapted to a target order.

[161] The at least one differentiation step can be the machining of the contour of the spacer to adapt it to a specific order, for example to the first order n1, more precisely, the machining of an outer periphery of the spacer. [162] In other words, the rectification of the contour or of the convex shape forms an outer periphery adapted to a specific targeted order, for example to the first order n1 (orders n1 <n,). For the outer peripheries, it will be necessary to change the tooling, and therefore the cutting station according to the order to be targeted, in order to form an outer periphery or pendulum body rolling track 42 specifically adapted to the target order;

[163] We now describe the manufacturing process of the first pendulum damping device 1 of order n1 according to a second embodiment of the invention. The steps of the second embodiment differ from those of the first embodiment in that:

- In a fourth step, a rolling member 40B is provided adapted to the targeted order n1 of said device. Said link member 40B is chosen from a range of link members suitable for different orders. A connecting member 20B is also provided, that is to say a spacer of predefined shape and which is independent of the order n1 of said device;

- In a fifth step, the standard connecting member 20B and the rolling member 40B adapted to the targeted order n1 are mounted, with the standard oscillating weight 14B within the cutout 15B of the support 12B;

[164] This method of manufacturing the second pendulum damping device 2 of order n2 is identical to the manufacturing process of the first pendulum damping device 1 of order n1 except that the elements adapted to an order are adapted to order n2.

[165] Advantageously, the various “non-standard” running gear 40B suitable for different orders n can include a manufacturing step common to all the running gear models of said range, followed by one or more steps of differentiation.

[166] The at least one common manufacturing step can be the forming of a semi-finished metal part common to the various rolling elements 40B, according to a predefined diameter. The formation of an initial metal part can be formed by forming a sheet, by striking or by machining or by pressing.

[167] The formation of an initial metal part may include a predefined radius R or predefined diameter. The predefined radius R or the default predefined diameter of the initial common metal part is dimensioned according to the order n, the highest in the range (order of the engine comprising the greatest number of cylinders).

[168] In other words, the other specific radii or diameters of the other remaining “non-standard” rolling gears are logically smaller than said predefined radius or predefined diameter by default.

[169] The at least one common manufacturing step is the formation of rolling elements 40 with a constant thickness or length "L";

[170] The at least one differentiation step can be the machining of the contour or of the rolling surface 43 of the rolling member to adapt it to a specific order, for example to the first order n1. That is, by adjusting and reducing the radius R or the diameter predefined, so as to adapt it to that of a specific order, for example to the first order n1 (orders n1 <n,). As a result, during the differentiation step, the rolling surface 43 of the rolling member is reduced in order to adapt it to a specific order of the engine.

[171] In these two embodiments, a range of "non-standard" parts can include at least two different models of parts, in other words two types of different shapes and sizes, each adapted according to one of the orders n1, n2 different to equip the pendulum damping devices.

[172] Advantageously, a range can include at least three different types of non-standard parts, as illustrated in FIGURES 3 to 5. A single range of "non-standard" parts can include at most six different types for a range. , and preferably at most five different types for a range. Advantageously, the support 12, 12B is precut, the cutout can form a window 15, 15B.

[173] Advantageously, the connecting member 20, 20B can be force-fitted into the standard oscillating weight 14, 14B during the fifth assembly step. Alternatively, the connecting member 20, 20B can be riveted with the oscillating weight 14,

14B standard in the fifth assembly step.

[174] Of course, the invention is not limited to the particular embodiments described above. In particular, combinations of the various alternative embodiments described above are possible.
