Description

DISPOSITIF DE MONTAGE UNIVERSEL PERMETTANT LE MONTAGE DE PLAQUETTES DE FREIN SUR UNE CHAPE D ' UN FREIN A DISQUE  UNIVERSAL MOUNTING DEVICE FOR ASSEMBLING BRAKE PADS ON A DISK OF A DISC BRAKE
[001] L'invention concerne le domaine des freins à disque et plus particulièrement un dispositif de montage de plaquettes de frein sur une chape d' étrier d'un frein à disque . [001] The invention relates to the field of disc brakes and more particularly to a brake pad mounting device on a caliper yoke of a disc brake.
[002] Dans un véhicule équipé de freins à disque, chaque roue qui doit être freinée comporte un disque de freinage associé à un dispositif de freinage destiné à freiner le mouvement de rotation du disque par friction. Le disque de freinage et le dispositif de freinage sont respectivement solidaires de la roue et du châssis du véhicule. [002] In a vehicle equipped with disc brakes, each wheel to be braked comprises a brake disc associated with a braking device for braking the rotational movement of the disc by friction. The brake disk and the braking device are respectively integral with the wheel and the chassis of the vehicle.
[003] Plus particulièrement, le dispositif de freinage comprend deux plaquettes de frein disposés de part et d'autre du disque de freinage. Chaque plaquette est mobile perpendiculairement au plan du disque selon une direction axiale et est guidé par des extensions prévues sur les bords latéraux appelées « oreilles de montage » dans des logements ménagés dans une chape d' étrier. [004] Des organes de commandes permettent d'exercer une pression sur les plaquettes de frein selon la direction axiale pour mettre ces dernières au contact du disque de freinage. Ainsi, lors d'un freinage, les deux plaquettes de frein viennent enserrer le disque de freinage par déplacement en direction du disque et par contact sur ce dernier, freinant la rotation du disque. [003] More particularly, the braking device comprises two brake pads disposed on either side of the brake disc. Each plate is movable perpendicularly to the plane of the disk in an axial direction and is guided by extensions provided on the side edges called "mounting ears" in housings formed in a yoke yoke. [004] Control members allow to exert pressure on the brake pads in the axial direction to put the latter in contact with the brake disc. Thus, during braking, the two brake pads come to grip the brake disc by moving towards the disc and by contact thereon, slowing the rotation of the disc.
[005] Pour améliorer le coulissement , il est répandu de monter les patins de frein sur la chape d' étrier au moyen de deux glissières, chacune des glissières étant montée intercalée entre l'une des oreilles d'une plaquette de frein et le logement associé ménagé dans la chape d' étrier. [006] Les glissières, de manière classique en soi, consistent en une lame rigide, le plus souvent métallique, pliée et agencée pour assurer, une fois fixée sur la chape d'étrier, le guidage des plaquettes de frein lors de leur déplacement par rapport à la chape. Le montage de telles glissières s'avère cependant fastidieux dans la mesure où il est nécessaire de procéder à autant d'opérations de montage qu'il est nécessaire de glissières. [005] To improve the sliding, it is common to mount the brake pads on the yoke clevis by means of two rails, each of the rails being mounted interposed between one of the ears of a brake pad and the housing partner arranged in the yoke of stirrup. [006] The slides, in a conventional manner per se, consist of a rigid blade, usually metal, folded and arranged to ensure, once fixed on the yoke clevis, guiding the brake pads during their movement by compared to the screed. The mounting of such slides is however tedious to the extent that it is necessary to perform as many editing operations as it is necessary slides.
[007] Afin de tenter de palier cet inconvénient, des glissières ont été proposées comprenant deux lames pliées raccordées l'une à l'autre par un bras de raccordement rigide. La figure 1A illustre un frein à disque 100 équipé de ce type de glissières. Comme pour les glissières classiques précédemment décrites, les lames 101, 102sont conformées pour recevoir l'une des oreilles 106A, 107A d'un des plaquettes de frein 106, 107. [007] In an attempt to overcome this drawback, slides have been proposed comprising two folded blades connected to one another by a rigid connection arm. Figure 1A illustrates a disc brake 100 equipped with this type of slides. As for the conventional slides previously described, the blades 101, 102 are shaped to receive one of the lugs 106A, 107A of one of the brake pads 106, 107.
[008] L'utilisation de telles glissières reste cependant limitée en ce sens qu'elles dépendent, de par leur structure, à une taille donnée d'un disque de freinage. En effet, le bras de raccordement 105 reliant les lames 101, 102 implique un écartement déterminé entre les lames. Les disques de freinage variant en terme d'épaisseur d'un véhicule à un autre, il est donc nécessaire de prévoir pour chaque taille de disque de freinage, i.e. épaisseur de disque de freinage, une glissière spécifique. On entend par « glissière spécifique » une glissière dont les lames présentent un écartement adapté pour permettre le passage du disque de freinage entre lesdites lames. En d'autres termes, à chaque épaisseur d'un disque de freinage, correspond une glissière spécifique, et par conséquent un outillage dédié. [008] The use of such slides remains however limited in that they depend, by their structure, a given size of a brake disc. Indeed, the connecting arm 105 connecting the blades 101, 102 implies a determined spacing between the blades. Since the brake discs vary in thickness from one vehicle to another, it is therefore necessary to provide for each braking disc size, i.e. brake disc thickness, a specific slide. The term "specific slide" means a slide whose blades have a spacing adapted to allow the passage of the brake disc between said blades. In other words, at each thickness of a braking disc, corresponds a specific slide, and therefore a dedicated tool.
[009] L'invention vise à remédier à ces problèmes en proposant un dispositif de montage des plaquettes de frein sur une chape d'un frein à disque pouvant être utilisé quelle que soit la taille du disque de freinage monté dans la chape. [009] The invention aims to remedy these problems by proposing a device for mounting the brake pads on a clevis of a disc brake that can be used whatever the size of the brake disc mounted in the screed.
[0010] A cet effet, et selon un premier aspect, l'invention propose un dispositif de montage de plaquettes de frein sur une chape d'un frein à disque, la chape comportant deux bras en forme de U disposés à une distance donnée l'un de l'autre pour permettre le passage d'un disque de freinage, le dispositif comprenant une première lame formant glissière apte à recevoir une oreille de montage d'une première plaquette et une deuxième lame formant glissière apte à recevoir une oreille de montage d'une deuxième plaquette, les première et deuxième lames étant maintenues écartées l'une à l'autre par un bras de raccordement, ledit bras de raccordement étant configuré pour permettre d'ajuster l'écartement entre les première et deuxième lames à la distance donnée entre les deux bras de la chape. For this purpose, and according to a first aspect, the invention provides a brake pad mounting device on a clevis of a disk brake, the yoke having two U-shaped arms disposed at a given distance. one of the other to allow the passage of a brake disc, the device comprising a first slide forming blade adapted to receive a mounting lug of a first wafer and a second slide forming blade adapted to receive a mounting lug a second wafer, the first and second blades being held apart from one another by a connecting arm, said connecting arm being configured to adjust the distance between the first and second blades at a distance; given between the two arms of the screed.
[0011] Ainsi, de par la configuration du bras de raccordement reliant les lames l'une à l'autre, la taille du dispositif de montage peut être modulée en fonction de la distance aménagée entre les deux bras de la chape et donc en fonction de la taille du disque de freinage. Thus, by the configuration of the connecting arm connecting the blades to one another, the size of the mounting device can be modulated according to the distance between the two arms of the yoke and therefore depending the size of the brake disc.
[0012] Avantageusement, le bras de raccordement comporte une zone déformable permettant d'ajuster l'écartement entre les première et deuxième lames. Plus particulièrement, la déformation du bras permet de réduire ou d' augmenter l'écartement entre les lames formant glissière. Advantageously, the connecting arm comprises a deformable zone for adjusting the spacing between the first and second blades. More particularly, the deformation of the arm makes it possible to reduce or increase the spacing between the slider blades.
[0013] Selon un mode de réalisation particulier, la zone déformable est formée de plis transversaux aptes à être dépliés en tout ou partie pour permettre l'ajustement du dispositif de montage à la chape sur laquelle il doit être fixé . [0014] A cette fin, le matériau utilisé, par exemple une tôle d'acier, présentera une capacité de mise en forme suffisante pour assurer cette formation de plis avec une altération des propriétés mécaniques aussi réduite que possible. According to a particular embodiment, the deformable zone is formed of transverse folds adapted to be unfolded in whole or in part to allow adjustment of the mounting device to the yoke on which it must be fixed. For this purpose, the material used, for example a steel sheet, will have sufficient shaping capacity to ensure the formation of folds with an alteration of mechanical properties as small as possible.
[0015] Avantageusement, la zone déformable s'étend entre les première et deuxième lames, sur tout ou partie de la longueur du bras de raccordement. Advantageously, the deformable zone extends between the first and second blades over all or part of the length of the connecting arm.
[0016] Selon un mode de réalisation, la zone déformable est configurée pour se déformer de manière symétrique par rapport à un plan de symétrie correspondant au plan du disque lorsque le dispositif de montage est fixé sur la chape . According to one embodiment, the deformable zone is configured to deform symmetrically with respect to a plane of symmetry corresponding to the plane of the disk when the mounting device is fixed on the yoke.
[0017] Avantageusement, le bras de raccordement comporte une première zone déformable ménagée sur une portion de jonction de la première lame à la deuxième lame et une deuxième zone déformable ménagée sur une portion de maintien du dispositif de montage sur la chape lorsque ledit dispositif est fixé sur cette dernière, la portion de jonction et la portion de maintien formant le bras de raccordement . Advantageously, the connection arm comprises a first deformable zone formed on a junction portion of the first blade to the second blade and a second deformable zone formed on a holding portion of the mounting device on the yoke when said device is fixed on the latter, the connecting portion and the holding portion forming the connecting arm.
[0018] L'invention concerne également un frein à disque de véhicule automobile comprenant au moins un dispositif de montage tel que décrit précédemment fixé sur une face latérale d'une chape. The invention also relates to a motor vehicle disc brake comprising at least one mounting device as described above attached to a side face of a yoke.
[0019] L'invention concerne également un frein à disque de véhicule automobile comprenant deux dispositifs de montage tel que décrits précédemment, lesdits dispositifs étant fixés sur la chape en regard l'un de l'autre. [0020] D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit, faite en référence aux dessins annexés, dans lesquels : The invention also relates to a motor vehicle disc brake comprising two mounting devices as described above, said devices being fixed on the yoke facing one another. Other objects and advantages of the invention will become apparent from the following description, made in reference to the accompanying drawings, in which:

[0021] Pour plus de clarté, les éléments identiques ou similaires des différents modes de réalisation sont repérés par des signes de référence identiques sur l'ensemble des figures .  - Figure 4 shows a perspective view of a mounting device according to a second embodiment of the invention. For clarity, identical or similar elements of the different embodiments are identified by identical reference signs throughout the figures.
[0022] En relation avec la figure 1B, il est décrit un frein à disque 1 comprenant deux plaquettes de frein 3, 4 montées sur une chape 5 fixe par l'intermédiaire de deux dispositifs de montage 2 selon l'invention. In connection with Figure 1B, there is described a disc brake 1 comprising two brake pads 3, 4 mounted on a yoke 5 fixed by means of two mounting devices 2 according to the invention.
[0023] Plus particulièrement, la chape 5 comporte deux bras 50, 51 juxtaposés en forme de U, les extrémités 50A, 50B, 51A, 51B de chaque bras 50, 51 disposées en vis-à-vis étant reliées entre elles par une zone de jonction 52, 53. Comme le montre la figure 1B, chacune des plaquettes de frein 3, 4 est disposée sur l'un des bras 50, 51, entre les extrémités 50A, 50B et 51A, 51B. More particularly, the yoke 5 comprises two arms 50, 51 juxtaposed U-shaped, the ends 50A, 50B, 51A, 51B of each arm 50, 51 arranged vis-à-vis being interconnected by a zone junction 52, 53. As shown in Figure 1B, each of the brake pads 3, 4 is disposed on one of the arms 50, 51, between the ends 50A, 50B and 51A, 51B.
[0024] De manière classique, les plaquettes de frein 3, 4 sont montées sur la chape 5 par l'intermédiaire de deux dispositifs de montage 2, appelés communément glissières, de forme complémentaire à celle de la chape 5, et plus particulièrement à celle des faces internes des branches de la forme en U des bras 50, 51. Ces dispositifs sont agencés pour permettre le guidage des plaquettes lors de leur déplacement en coulissement l'une vers lxautre ou en sens inverse . Conventionally, the brake pads 3, 4 are mounted on the yoke 5 by means of two mounting devices 2, commonly called slides, complementary shape to that of the yoke 5, and more particularly to that the inner faces of the arms of the U-shaped arms 50, 51. These devices are arranged to allow the guiding of the wafers during their sliding displacement one to l x other or in the opposite direction.
[0025] Plus particulièrement, chaque dispositif de montage 2 comprend une première et une deuxième lame 20, 40 reliées entre elles par un bras de raccordement 30 lequel maintient lesdites lames 20, 40 à une distance déterminée d l'une de l'autre. More particularly, each mounting device 2 comprises a first and a second blade 20, 40 interconnected by a connecting arm 30 which maintains said blades 20, 40 at a determined distance from one another.
[0026] Afin d'assurer le guidage des plaquettes, chaque lame 20, 40 présente une pliure formant une gorge 21, 41 destinées à recevoir des oreilles de montage 3A, 3B 4A, 4B (3B, 4B non visibles sur les figures) prévues sur les faces latérales des plaquettes de freins 3, 4. La forme de ces gorges peut être en U ou en V-figure 4), ou selon toute autre forme. Ces formes sont avantageusement reprises sur les faces latérales internes 500, 510 des bras 50, 51. Par le terme « faces latérales internes », on désigne les faces en regard desquelles les plaquettes de frein 3, 4 doivent être disposées. To ensure the guiding of the plates, each blade 20, 40 has a fold forming a groove 21, 41 for receiving mounting ears 3A, 3B 4A, 4B (3B, 4B not visible in the figures) provided on the lateral faces of the brake pads 3, 4. The shape of these grooves can be in U or V-Figure 4), or in any other form. These forms are advantageously taken up on the internal lateral faces 500, 510 of the arms 50, 51. By the term "internal lateral faces", one designates the faces opposite which the brake pads 3, 4 must be arranged.
[0027] Plus particulièrement, les gorges 21, 41 de chaque lame 20, 40 sont délimitées par une aile supérieure 210, 410, une aile inférieure 212, 412 et un fond 211, 411, le fond 211, 411 de la gorge et l'aile inférieure 212, 412 assurant respectivement les fonctions de guidage et de coulissement des oreilles de montage 3A, 3B, 4A, 4B des plaquettes de frein par rapport à la chape 5. More particularly, the grooves 21, 41 of each blade 20, 40 are delimited by an upper flange 210, 410, a lower flange 212, 412 and a bottom 211, 411, the bottom 211, 411 of the groove and the lower wing 212, 412 respectively providing the guiding and sliding functions of the mounting lugs 3A, 3B, 4A, 4B of the brake pads relative to the yoke 5.
[0028] Selon l'invention, le bras de raccordement 30 est configuré pour permettre un ajustement de la distance d entre les deux lames 20, 40. According to the invention, the connecting arm 30 is configured to allow adjustment of the distance d between the two blades 20, 40.
[0029] Pour ce faire, et selon le mode de réalisation décrit, le bras de raccordement 30 comporte une zone déformable 31. La présence de cette zone a pour avantage de permettre d'adapter l'écartement des deux lames 20, 40 entre elles en fonction de l'écartement entre les deux bras 50, 51 de la chape 5. To do this, and according to the embodiment described, the connecting arm 30 comprises a deformable zone 31. The presence of this zone has the advantage of allowing to adjust the spacing of the two blades 20, 40 between them according to the spacing between the two arms 50, 51 of the yoke 5.
[0030] Dans le mode de réalisation décrit, la zone déformable 31 comporte plusieurs plis transversaux 31a aptes à être dépliés en tout ou partie pour permettre l'ajustement du dispositif de montage 2 à la chape sur laquelle il doit être fixé. Ainsi, comme illustré sur la figure 3, lorsque la distance y séparant les bras 50, 51 de la chape 5 diffère de la distance d entre les lames 20, 40, il est procédé à un réajustement de la longueur du bras de raccordement. Plus particulièrement, lorsque la distance y séparant les bras 50, 51 de la chape 5 est supérieure à la distance d entre les lames 20, 40, il est procédé à un allongement du bras de raccordement par déploiement des plis de la zone déformable 31. La zone déformable 31 sera déployée jusqu'à obtenir un écartement entre les lames 20, 40 sensiblement équivalent à la distance y séparant les bras 50, 51 de la chape 5. In the embodiment described, the deformable zone 31 comprises several transverse folds 31a able to be unfolded in whole or in part to allow the adjustment of the mounting device 2 to the yoke on which it must be fixed. Thus, as illustrated in Figure 3, when the distance between the arms 50, 51 of the yoke 5 differs from the distance d between the blades 20, 40, it is readjusted the length of the connecting arm. More particularly, when the distance between the arms 50, 51 of the yoke 5 is greater than the distance d between the blades 20, 40, it is proceeded to an elongation of the connecting arm by unfolding the folds of the deformable zone 31. The deformable zone 31 will be deployed until a separation between the blades 20, 40 is substantially equivalent to the distance y between the arms 50, 51 of the yoke 5.
[0031] La zone déformable 31 sera désignée par la suite sous l'expression de zone d'ajustement 31. [0032] Selon une configuration avantageuse, la zone d'ajustement 31 présente une déformation plastique suffisante pour permettre également un rapprochement des lames l'une de l'autre. The deformable zone 31 will be designated hereinafter as the adjustment zone 31. According to an advantageous configuration, the adjustment zone 31 has a plastic deformation. sufficient to allow the blades to move closer to each other.
[0033] Comme illustré sur les figures 2 et 3, la zone d'ajustement 31 s'étend entre les première et deuxième lames 20, 40. Il est bien entendu évident qu'il s'agit d'un exemple de réalisation, et qu'elle peut ne pas s'étendre sur toute la longueur du bras de raccordement 30. Elle sera cependant définie de manière à assurer un écartement des lames 20, 40 suffisant pour permettre un ajustement du dispositif de montage 2 à toutes les tailles des disques de freinage . As illustrated in Figures 2 and 3, the adjustment zone 31 extends between the first and second blades 20, 40. It is of course obvious that this is an embodiment, and that it may not extend over the entire length of the connecting arm 30. It will however be defined so as to ensure a spacing of the blades 20, 40 sufficient to allow adjustment of the mounting device 2 to all sizes of disks braking.
[0034] Dans le mode réalisation précédemment décrit, le dispositif de montage 2 est maintenu sur la chape 5 par emboîtement du fait de la forme et le cas échéant de la fonction ressort conférée aux lames 20, 40 lors de leur fabrication . In the embodiment described above, the mounting device 2 is held on the yoke 5 by interlocking due to the shape and if necessary the spring function conferred to the blades 20, 40 during their manufacture.
[0035] La figure 4 illustre un dispositif de montage 2 dont le maintien est assuré non pas par les lames 20, 40 elles-mêmes, mais par le bras de raccordement 30, ce dernier portant des moyens de maintien. Figure 4 illustrates a mounting device 2 which is maintained not by the blades 20, 40 themselves, but by the connecting arm 30, the latter carrying holding means.
[0036] Plus particulièrement, dans le mode de réalisation illustré, le bras de raccordement 30 comprend une portion de raccordement 300 reliant les lames 20, 40 l'une à l'autre et une portion 310 agencée pour maintenir le dispositif de montage 2 sur la chape 5. More particularly, in the illustrated embodiment, the connecting arm 30 comprises a connecting portion 300 connecting the blades 20, 40 to one another and a portion 310 arranged to hold the mounting device 2 on the screed 5.
[0037] La portion 310 comportent deux languettes 60, 62 s' étendant entre les deux lames 20, 40, dans une direction opposée à celle de l'ouverture des gorges associées 21, 41 de manière à ce que, lorsque le dispositif de montage 2 est placé sur la chape 5, chaque lame 20, 40 chevauchant l'un des bras de la chape 50, 51, les languettes de maintien 60, 62 viennent en appui contre la face inférieure de la zone de jonction 52, 53 de la chape 5. The portion 310 comprises two tongues 60, 62 extending between the two blades 20, 40, in a direction opposite to that of the opening of the associated grooves 21, 41 so that when the mounting device 2 is placed on the yoke 5, each blade 20, 40 overlapping one of the arms of the yoke 50, 51, the retaining tabs 60, 62 abut against the underside of the junction zone 52, 53 of the yoke 5.
[0038] Afin de renforcer les languettes 60, 62, ces dernières sont reliées l'une à l'autre par une entretoise 61 qui constitue également une zone d'ajustement. To reinforce the tabs 60, 62, the latter are connected to one another by a spacer 61 which also constitutes an adjustment zone.
[0039] Afin de permettre d'ajuster l'écartement entre les deux lames 20, 40 à la distance ménagée entre les deux bras 50, 51 de la chape 5, l'entretoise 61 est constituée pour se déformer conjointement avec la zone d'ajustement 31 de la portion de raccordement 300. L'entretoise 61 constitue ainsi une deuxième zone déformable du bras de raccordement 30. To allow to adjust the spacing between the two blades 20, 40 at the distance between the two arms 50, 51 of the yoke 5, the spacer 61 is formed to deform jointly with the zone of adjustment 31 of the connecting portion 300. The spacer 61 thus constitutes a second deformable zone of the connecting arm 30.
[0040] La ou les zone (s) déformable ( s ) étant réalisée (s) à partir d'une tôle métallique, telle qu'une tôle d'acier, la déformation est obtenue à l'aide d'un outil industriel. Les caractéristiques de cette tôle, à la fois par son épaisseur et sa nuance sont telles que, une fois la zone ajustée à la chape par un outil industriel adapté, cette zone ne se déforme plus lors du fonctionnement du dispositif de freinage. [0041] Avantageusement, les deux zones déformables 31, 61 sont configurées pour se déformer symétriquement par rapport à un plan de symétrie correspondant au plan du disque de freinage lorsque le dispositif de montage 2 est fixé sur la chape 5. [0042] L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention. The zone (s) deformable (s) being made (s) from a metal sheet, such as a steel sheet, the deformation is obtained using an industrial tool. The characteristics of this sheet, both by its thickness and its shade are such that, once the area adjusted to the yoke by a suitable industrial tool, this area no longer deforms during operation of the braking device. Advantageously, the two deformable zones 31, 61 are configured to deform symmetrically with respect to a plane of symmetry corresponding to the plane of the braking disk when the mounting device 2 is fixed on the yoke 5. [0042] The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
