Description
La présénte invention concerne d'une manière générale les dispositifs amortisseurs de torsion, notamment les frictions d'embrayage pour vénicules automobiles, du genre comportant, au moins trois parties coaxiales deux à deux montées rotatives l'une par rapport à l'autre dans les limites d'un secteur de débattement angulaire déterminé et à l'encontre des moyens élastiques, à savoir une première -partie comportant un moyeu, une deuxième partie comportant un voile de moyeu avec, entre lui et le moyeu, des moyens d'engrènement à jeu, et une troisième partie comportant au moins un flasque, qui forme transversalement une pièce annulaire autour du moyeu mais sans relation avec celui-ci. The present invention relates in general to torsion damping devices, in particular clutch friction for motor vehicles, of the type comprising, at least three coaxial parts two to two rotatably mounted relative to one another in the limits of a determined angular displacement sector and against the elastic means, namely a first part comprising a hub, a second part comprising a hub plate with, between it and the hub, meshing means with game, and a third part comprising at least one flange, which transversely forms an annular part around the hub but without relation to the latter.
On a décrit dans la demande principale FR-.A-8704614 du 2-4-87 un dispositif amortisseur de torsion, notamment pour véhicules automobiles, comportant un moyeu (10), au moins un voile de moyeu (12), qui forme trans.versalement une pièce annulaire autour du moyeu (10) avec, entre lui et ledit moyeu (10), des moyens d'engrènement à jeu et des moyens élastiques à action circonférentielle (18),.au moins un flasque (23), accouplé au voile de moyeu (12) par des moyens élastiques à action circonférentielle (33A, 33B), qui forme transversalement une pièce annulaire autour du moyeu (10), mais sans relation avec celui-ci, un organe d'interposition comportant deux flasques mobiles (138, 140), sensibles à la force centrifuge, montés mobiles entre une position d'attente pour laquelle ils sont inactifs, et-, au-delà d'une vitesse de rotation déterminée, une position de service, pour laquelle intervenant entre le moyeu (10) et le voile de moyeu (12); pour un sens de rotation relatif au moins de ceux-ci, ils sollicitent, dans ledit sens de rotation, une portion au moins des moyens élastiques à action circonférentielle autres que ceux agissant normalement entre eux, et des moyens élastiques de rappel (65) aptes à solliciter en direction de leur dite position d'attente lesdits flasques mobiles (138, 140).Cette demande met en oeuvre deux flasques mobiles (138, 140), qui sont reliés l'un à l'autre par àu moins un organe de transmission (239) pivotant par rapport à ceux-ci, en sorte qu'un déplacement radial de l'un des flasques mobiles (138,140) provoque un pivotement de l'organe de transmission et un déplacement radial en sens inverse de l'autre flasque mobile (138,140). There has been described in the main application FR-.A-8704614 of 2-4-87 a torsion damping device, in particular for motor vehicles, comprising a hub (10), at least one hub wall (12), which forms trans .versally an annular part around the hub (10) with, between itself and said hub (10), interlocking means with play and elastic means with circumferential action (18),. at least one flange (23), coupled to the hub web (12) by elastic means with circumferential action (33A, 33B), which transversely forms an annular part around the hub (10), but without relation to the latter, an interposing member comprising two movable flanges (138, 140), sensitive to centrifugal force, mounted movable between a waiting position for which they are inactive, and-, beyond a determined rotation speed, a service position, for which intervening between the hub (10) and the hub web (12); for at least one relative direction of rotation, they urge, in said direction of rotation, at least a portion of the elastic means with circumferential action other than those acting normally between them, and elastic return means (65) capable to solicit in the direction of their said waiting position said movable flanges (138, 140). This request implements two movable flanges (138, 140), which are connected to each other by at least one member of transmission (239) pivoting relative to them, so that a radial displacement of one of the movable flanges (138,140) causes a pivoting of the transmission member and a radial displacement in opposite direction of the other flange mobile (138,140).
L'organe de transmission est monté radialement fixe et rotatif par rapport aux flasques mobiles. Des moyens d'entraînement sont prévus entre l'organe de transmission et chacun des flasques mobiles. The transmission member is mounted radially fixed and rotatable relative to the movable flanges. Drive means are provided between the transmission member and each of the movable flanges.
Pour accrochage des moyens élastiques, chaque flasque mobile 138, 140 présente une patte 250 en forme de L formée à la faveur d'un retour en équerre. For attachment of the elastic means, each movable flange 138, 140 has a tab 250 in the shape of an L formed by virtue of a square return.
La mise au point de l'invention a démontré l'intérêt d'améliorer la résistance de la patte. La demanderesse a recherché également à simplifier le montage. The development of the invention has demonstrated the advantage of improving the resistance of the tab. The Applicant has also sought to simplify assembly.
La présente invention a pour objet de résoudre ces problèmes et donc de perfectionner le dispositif- de la demande principale. The object of the present invention is to solve these problems and therefore to improve the device of the main application.
Suivant l'invention, un dispositif amortisseur de torsion, notamment pour véhicules automobiles, selon la revendication 1 du brevet principal, dans lequel, pour accrochage des moyens élastiques de rappel, chaque flasque mobile présente une patte, est caractérisé en ce que la patte s'étend globalement axialement et en ce qu'elle possède un bord relevé par rapport au plan du flasque mobile. Grâce à l'invention, d'une part, la patte ne risque pas d'être endommagée lors du pliage en équerre, et, d'autre part, grâce au bord relevé il devient possible d'accrocher aisément l'extrémité du ressort de rappel et donc de simplifier le montage. According to the invention, a torsion damping device, in particular for motor vehicles, according to claim 1 of the main patent, in which, for hooking elastic return means, each movable flange has a tab, is characterized in that the tab s 'extends generally axially and in that it has a raised edge relative to the plane of the movable flange. Thanks to the invention, on the one hand, the lug is not likely to be damaged during bending at an angle, and, on the other hand, thanks to the raised edge it becomes possible to easily hook the end of the spring. reminder and therefore simplify assembly.
Selon une autre caractéristique, la patte est délimitée par l'ouverture çentrale du flasque mobile et par une ouverture de dégagement de celui-ci située en dessous de la boutonnière. According to another characteristic, the tab is delimited by the central opening of the movable flange and by a release opening of the latter located below the buttonhole.
Ainsi seul l'extrémité de la patte peut être tranchée ce qui augmente la robustesse de la patte. Avantageusement la patte possède un creux évasé au niveau du bord de l'ouverture de dégagement. Thus only the end of the tab can be cut which increases the robustness of the tab. Advantageously, the tab has a flared hollow at the edge of the clearance opening.
Ceci permet le positionnement automatique de l'extrémité en forme de crosse d'évêque d'un ressort de rappel. Le montage se fait en tirant transversalement l'extrémité du ressort s'ouvrant puis restant serrée sur la patte pour diminution des bruits. On peut également monter le ressort perpendiculairement à la patte puis effectuer un pivotement. This allows automatic positioning of the bishop's butt end of a return spring. The assembly is done by transversely pulling the end of the opening spring then remaining tight on the tab to reduce noise. You can also mount the spring perpendicular to the lug and then pivot.

Dans la variante représentée chaque flasque mobile 138,140 présente une patte 250 pour l'accrochage des moyens élastiques de rappel 65 ici des ressorts à boudin. In the variant shown each movable flange 138, 140 has a tab 250 for hooking the elastic return means 65 here coil springs.
Suivant l'invention (figure 6) la patte 250 s'étend axialement, perpendiculairement à la face latérale 261, globalement transversale, du flasque mobile 138,140 et possède un bord relevé 350 en surélévation par rapport au plan du flasque mobile 138,140. Le bord est relié par une zone arrondie 351 à une zone d'enracinement 352 dans le plan du flasque.According to the invention (Figure 6) the tab 250 extends axially, perpendicular to the lateral face 261, generally transverse, of the movable flange 138,140 and has a raised edge 350 raised above the plane of the movable flange 138,140. The edge is connected by a rounded zone 351 to a rooting zone 352 in the plane of the flange.
La patte 250 est. délimitée par l'ouverture centrale 45 et une ouverture de dégagement 353 située en-dessous de la boutonnière 43. Leg 250 is. delimited by the central opening 45 and a clearance opening 353 located below the buttonhole 43.
Cette patte 250 présente, au bord de l'ouverture 353; un creux 355 évasé pour recevoir l'extrémité arrondie 354, en forme de crosse d'évêque, du ressort 65 réalisé à laide d'un fil de section circulaire. This tab 250 has, at the edge of the opening 353; a hollow 355 flared to receive the rounded end 354, in the form of a bishop's butt, of the spring 65 produced using a wire of circular section.
Le creux 355 forme donc un berceau pour l'extrémité 354, qui constitue une agrafe avec une portion teminale courbe d'engagement 356, se raccordant à une portion circulaire 357, s'étendant sur plus de 1800, elle-même raccordée à une portion globalement verticale 358. Un rétrécissement de largeur D (figure 7) est donc créé. On notera que la largeur D est inférieure à l'épaisseur de la patte et que le montage du ressort 65 se fait par clipsage en tirant transversalement, l'autre extrémité 359 du ressort 65 étant accrochée dans le trou 246 de l'organe 239. The hollow 355 therefore forms a cradle for the end 354, which constitutes a staple with a curved teminal engagement portion 356, connecting to a circular portion 357, extending over more than 1800, itself connected to a portion generally vertical 358. A narrowing of width D (FIG. 7) is therefore created. It will be noted that the width D is less than the thickness of the tab and that the mounting of the spring 65 is done by clipping by pulling transversely, the other end 359 of the spring 65 being hooked in the hole 246 of the member 239.
En effet, il suffit d'introduire l'extrémité 354 dans l'ouverture 353 au niveau du creux 355 jusqu'à contacts de la portion 356 avec la patte 250 et de tirer. Lors de cette opération l'extrémité 354 s'ouvre (la largeur D augmentant), puis se referme une fois que la patte 250 a franchi le rétrécissement. Après montage l'extrémité 354 peut rester agrafée et donc serrée sur la patte 250, le rétrécissement ayant alors une largeur supérieure à la largeur D. Cette disposition réduit les bruits et le phénomènes d'usure. Le montage du ressort peut se faire également perpendiculairement au plan du flasque, la hauteur de la patte étant alors concernée, puis par redressement rendu possible par la portion circulaire 357. Indeed, it suffices to introduce the end 354 into the opening 353 at the hollow 355 until the portion 356 contacts the tab 250 and to pull. During this operation, the end 354 opens (the width D increases), then closes once the tab 250 has crossed the narrowing. After mounting the end 354 can remain stapled and therefore clamped on the tab 250, the narrowing then having a width greater than the width D. This arrangement reduces noise and the phenomenon of wear. The mounting of the spring can also be done perpendicular to the plane of the flange, the height of the tab then being concerned, then by straightening made possible by the circular portion 357.
Avantageusement à l'état libre la largeur D est inférieure à l'épaisseur de la patte 250, identique à celle du flasque 138, 140, en étant supérieure à la hauteur de la patte au niveau du creux 355 pour faciliter un montage dans tous les sens.Advantageously in the free state, the width D is less than the thickness of the tab 250, identical to that of the flange 138, 140, being greater than the height of the tab at the level of the hollow 355 to facilitate mounting in all meaning.
Avantageusement, les arêtes supérieures de la patte 250 sont chanfreinées. L'ouverture de l'extrémité 354 est facilitée par la portion 356, qui constitue un chanfrein de montage, tandis que le creux 355 positionne le ressort 65 qui trouve automatiquement sa place grâce à l'évasement; les arêtes chanfreinées de la patte 250 facilitant le montage et évitant des phénomènes d'incrustation. Advantageously, the upper edges of the tab 250 are chamfered. The opening of the end 354 is facilitated by the portion 356, which constitutes a mounting chamfer, while the hollow 355 positions the spring 65 which automatically finds its place thanks to the flaring; the chamfered edges of the tab 250 facilitating assembly and avoiding incrustation phenomena.
On notera que le montage peut se faire de part et d'autre du flasque mobile et que la patte 250 est résistance et ne risque pas d'être endommagée par un pliage en équerre ; seule l'extrémité du bord 350 est tranchée. It will be noted that the mounting can be done on either side of the movable flange and that the tab 250 is resistant and does not risk being damaged by bending at an angle; only the end of the edge 350 is cut.
Le crevé 199 s'étend transversalement, l'organe de transmission comportant alors un dégagement 303, en conséquence, comme décrit dans le ler certificat d'addition 87 10991 avec deux bords 304,305 perpendiculaires l'un par rapport à l'autre. The punctured 199 extends transversely, the transmission member then comprising a clearance 303, consequently, as described in the 1st certificate of addition 87 10991 with two edges 304, 305 perpendicular to one another.
Le voile 12 et le contre-voile 46 sont identiques, pour une meilleure répartition des efforts, et sont reliés et fixés par quatre entretoises 144 disposées sensiblement sur la même circonférence que les entretoises 24. The web 12 and the anti-web 46 are identical, for a better distribution of the forces, and are connected and fixed by four spacers 144 arranged substantially on the same circumference as the spacers 24.
Les deux entretoises 44 servent donc uniquement au guidage. The two spacers 44 therefore serve only for guiding.
Les rondelles de frottement 71, 72 sont en matière synthétique. On notera que la rondelle 71 est identique au palier 30 tandis que la rondelle 72 est identique à une rondelle 401 adjacente à l'autre rondelle de guidage et possède des têtons rectangulaires 402 engagés chacun dans une ouverture 403 de la rondelle de guidage 23. The friction washers 71, 72 are made of synthetic material. It will be noted that the washer 71 is identical to the bearing 30 while the washer 72 is identical to a washer 401 adjacent to the other guide washer and has rectangular pins 402 each engaged in an opening 403 of the guide washer 23.
Tout ceci provient de l'identité des rondelles de guidage. Les rondelles 70,74 consistent en des rondelles
Belleville.All this comes from the identity of the guide washers. Washers 70,74 consist of washers
Beautiful city.
Chaque flasque mobile possède deux dents 150, conjointement le moyeu 10 présente des rainures délimités par des bossages 154 pour recevoir ces dents 150. Each movable flange has two teeth 150, together the hub 10 has grooves delimited by bosses 154 to receive these teeth 150.
On notera l'inclinaison desdites dents 150 et rainures facilitant leur engagement mutuel aussi bien que leur désengagement ultérieur. Note the inclination of said teeth 150 and grooves facilitating their mutual engagement as well as their subsequent disengagement.
On voit en 155 le bombé du rebord radial de la fenêtre et en 241, 242 les pattes sous forme de retour en équerre pénétrant dans les encoches 243, 244 latérales des flasques 138, 140 pour formaticn des moyens d'entraînement entre l'organe de transmission 239 et chacun des flasque mobiles 138, 140. We see in 155 the domed radial rim of the window and in 241, 242 the tabs in the form of an angled return penetrating into the notches 243, 244 lateral of the flanges 138, 140 for formaticn drive means between the body transmission 239 and each of the movable flanges 138, 140.
On rappellera la disposition symétrique des pattes 243, 244 et que le déplacement-d'un des flasques 138, 140 entraîne grâce aux moyens d'entraînement 241, 243 et 242, 244 un pivotement de l'organe 239 autour de l'axe et un déplacement en sens inverse de l'autre flasque 140, 138. We will recall the symmetrical arrangement of the legs 243, 244 and that the movement of one of the flanges 138, 140 causes, by means of the drive means 241, 243 and 242, 244, a pivoting of the member 239 about the axis and a displacement in the opposite direction of the other flange 140, 138.
