Agencement pour le montage d'un élément de protection sur une extrémité d'une barre appartenant à un mécanisme d'entraînementArrangement for mounting a protection element on one end of a bar belonging to a drive mechanism
[0001] L'invention propose un agencement pour le montage d'un dément de protection d'une articulation sur une extrémité d'une barre appartenant à un mécanisme d'entiaînement d'au moins un balai d'essuyage.The invention provides an arrangement for mounting a protective element of a hinge on one end of a bar belonging to a housing mechanism of at least one wiper blade.
[0002] L'invention propose plus particulièrement un agencement pour le montage d'un élément de protection d'une articulation sur une extrémité d'une première barre appartenant à une tringlerie d'un système d'essuyage, ladite extrémité de k première barre étant reliée à une extrémité libre d'une deuxième barre du système d'essuyage, par l'intermédiaire de moyens d'articulation qui sont du type à rotule, ledit élément de protection consistant en un joint de rotule qui est agencé entre les extrémités des deux barres de manière à envelopper au moins en partie les moyens d'articulation.The invention more particularly proposes an arrangement for mounting a protection element of a hinge on one end of a first bar belonging to a linkage of a wiper system, said end of k first bar. being connected to a free end of a second bar of the wiper system, by means of hinge means which are of the ball type, said protection element consisting of a ball joint which is arranged between the ends of the two bars so as to envelop at least partially the hinge means.
[0003] On a représenté à k figure 1 une partie d'un système d'essuyage 10 pour un véhicule automobile selon l'art antérieur, qui comporte un palier 12 de guidage d'un arbre 14 d'entiaînement d'un baki d'essuyage (non représenté), en rotation autour d'un axe A globalement vertical.[0003] FIG. 1 shows part of a wiper system 10 for a motor vehicle according to the prior art, which comprises a bearing 12 for guiding a drive shaft 14 of a baki d wiping (not shown), rotating about an axis A generally vertical.
[0004] L'arbre 14 est entiaîné en rotation alternée autour de son axe principal A par un ensemble motoréducteur (non représenté) au moyen d'une timonerie, ou tringlerie 16.The shaft 14 is alternately rotated about its main axis A by a geared motor assembly (not shown) by means of a wheelhouse, or linkage 16.
[0005] A cet effet, l'arbre 14 porte, à son extrémité inférieure, un levier 20 qui s'étend globalement perpendicukirement à l'axe principal A de l'arbre 14. Le levier 20 est relié à son extrémité libre 20a à une première extrémité 18 d'une bielle 22 qui est entraînée par le motoréducteur.For this purpose, the shaft 14 carries, at its lower end, a lever 20 which extends generally perpendicular to the main axis A of the shaft 14. The lever 20 is connected to its free end 20a to a first end 18 of a connecting rod 22 which is driven by the geared motor.
[0006] De plus, dans le cas d'un système d'essuyage du pare-brise avant d'un véhicule comportant deux bakis d'essuyage, et par conséquent deux arbres 14 d'entraînement, dont un seul arbre 14 est représenté ici, chaque arbre 14 porte un levier 20, et les extrémités libres de ces leviers 20 sont reliées par une barre de liaison 24 de sorte que les mouvements des deux arbres 14 sont liés.In addition, in the case of a wiper system of the front windshield of a vehicle having two wiping bulbs, and therefore two drive shafts 14, a single shaft 14 is shown here each shaft 14 carries a lever 20, and the free ends of these levers 20 are connected by a connecting bar 24 so that the movements of the two shafts 14 are connected.
[0007] L'extrémité 18 de k bielle 22 est articulée par mpport à l'extrémité 20a du levier 20 par une liaison du type à rotule, qui comporte ici un doigt 26 qui est monté sur l'extrémité libre 20a du levier 20, et dont l'embout 28 du doigt 26 est sphérique et est apte à être reçu dans un logement 30 associé, qui est porté par l'extrémité 18 de k bielle 22.The end 18 of k connecting rod 22 is articulated by mpport to the end 20a of the lever 20 by a connection of the ball type, which here comprises a finger 26 which is mounted on the free end 20a of the lever 20, and whose tip 28 of the finger 26 is spherical and is adapted to be received in an associated housing 30, which is carried by the end 18 of k connecting rod 22.
[0008] Ce logement 30 est de forme cylindrique de diamètre interne globalement égal au diamètre de l'embout sphéique 28 du doigt 26, et le logement 30 est réalisé dans un dément 32 rapporté sur l'extrémité 18 de k bielle 22, généralement appelé "boîte à rotule", et qui est monté dans un orifice 38 complémentaire de l'extrémité 18 de k bielle 22. [0009] Enfin, le doigt 26 est enveloppé par un joint de rotule 36 qui est agencé entre l'extrémité 18 de k bielle 22 et l'extrémité libre 20a du levier 20, pour protéger l'embout sphérique 28 et le logement 30 de divers déments polluants tels que de l'eau ou des poussières. [0010] La barre de liaison 24 est elle aussi montée articulée par rapport à l'extrémité 20a du levier 20 par une liaison à rotule simikire à celle reliant l'extrémité 18 de k bielle 22 à l'extrémité 20a du levier 20. [0011] La barre de liaison 24 porte ainsi une boîte à rotule 32 simikire à celle qui est portée par l'extrémité 18 de k bielle 22. [0012] Aussi, l'extrémité 20a du levier porte deux doigts 26, chacun associé à k bielle 22 ou à k barre de liaison 24. [0013] Enfin, un joint de rotule 36 est aussi agencé entre k barre de liaison 24 et l'extrémitéThis housing 30 is of cylindrical shape with an internal diameter generally equal to diameter of the spherical tip 28 of the finger 26, and the housing 30 is made in a member 32 attached to the end 18 of k connecting rod 22, generally called "ball-and-socket", and which is mounted in a hole 38 complementary to the end 18 of k rod 22. Finally, the finger 26 is wrapped by a ball joint 36 which is arranged between the end 18 of k rod 22 and the free end 20a of the lever 20, to protect the ball end 28 and housing 30 of various polluting elements such as water or dust. The connecting bar 24 is also mounted articulated relative to the end 20a of the lever 20 by a ball joint connection to that connecting the end 18 of k connecting rod 22 at the end 20a of the lever 20. [ 0011] The connecting bar 24 thus carries a 32 simikire ball joint to that which is carried by the end 18 of k connecting rod 22. [0012] Also, the end 20a of the lever carries two fingers 26, each associated with k connecting rod 22 or at the connecting rod 24. Finally, a ball joint 36 is also arranged between the connecting bar 24 and the end
20a du levier 20, pour protéger cette deuxième articuktion. [0014] Selon les enseignements de l'art antérieur, chaque joint de rotule 36 est monté par emboîtement élastique sur l'extrémité 18 de k bielle 22, par exemple sur une partie associée de k boîte à rotule 32. [0015] Un tel mode de montage du joint de rotule 36 pose de nombreux problèmes lors d'un montage à k chaîne du système d'essuyage 10. [0016] En effet, il est parfois difficile d'orienter et de saisir correctement le joint de rotule 36 sur une ligne de montage, avant son montage sur l'extrémité 18 de k bielle 22. [0017] De plus, l'emboîtement élastique est parfois mal réalisé, ce qui peut provoquer une désolidarisation du joint de rotule 36 d'avec l'extrémité 18 de k bielle 22. [0018] L'invention a pour but de proposer un agencement pour le montage d'un joint de rotule sur une extrémité de bielle, permettant de résoudre de tels problèmes de montage. [0019] Dans ce but, l'invention propose un agencement du type décrit précédemment, caractérisé en ce que le joint de rotule est réalisé par moukge d'une matière pkstique sur l'extrémité de k première barre. [0020] Selon d'autres caractéristiques de l'invention, prises isolément ou en combinaison :20a of the lever 20, to protect this second articuktion. According to the teachings of the prior art, each ball joint 36 is mounted by resilient interlocking on the end 18 of k connecting rod 22, for example on an associated part of k ball box 32. [0015] Such a The method of mounting the ball joint 36 poses many problems during a chain mounting of the wiper system 10. [0016] Indeed, it is sometimes difficult to correctly orient and grasp the ball joint 36 on the ball joint. a mounting line, before mounting on the end 18 of k rod 22. [0017] In addition, the resilient interlock is sometimes poorly achieved, which can cause a disengagement of the ball joint 36 from the end The invention aims to provide an arrangement for mounting a ball joint on a connecting rod end, to solve such mounting problems. For this purpose, the invention provides an arrangement of the type described above, characterized in that the ball joint is formed by mukge of a material on the piskel of the first bar. According to other features of the invention, taken separately or in combination:
- l'extrémité de k première barre comporte au moins un orifice qui est apte à être traversé par une partie du joint de rotule ; - l'extrémité de k première barre comporte un trou central de montage d'un composant des moyens d'articulation et comporte une pluralité d'orifices qui sont répartis régulièrement autour du trou central ;- The end of the first bar comprises at least one orifice which is adapted to be traversed by a portion of the ball joint; the end of the first bar comprises a central mounting hole of a component of the articulation means and comprises a plurality of orifices which are evenly distributed around the central hole;
- l'extrémité de k première barre est globalement pkne, et le joint de rotule comporte une première portion enveloppant les moyens d'articuktion qui est agencée sur une première face de kdite extrémité, située en vis-à-vis de k deuxième barre et qui comporte une deuxième portion de solidarisation du joint de rotule à l'extrémité de k première barre, qui est agencée sur k deuxième face de l'extrémité de k première barre, et les deux portions du joint de rotule sont reliées par k partie du joint de rotule traversant l'orifice de l'extrémité de k première barre ;- The end of k first bar is generally pkne, and the ball joint comprises a first portion surrounding the articuktion means which is arranged on a first face of kdite end, located vis-à-vis the second bar and which comprises a second securing portion of the ball joint at the end of the first bar, which is arranged on the second face of the end of the first bar, and the two portions of the ball joint are connected by k part of the ball joint passing through the hole of the end of the first bar;
- k première barre est une bielle de k tringlerie du système d'essuyage et k deuxième barre est un levier qui est porté par un arbre d'entraînement d'un baki d'essuyage en rotation alternée autour de l'axe principal de l'arbre.The first bar is a link rod of the wiper system and the second bar is a lever which is carried by a drive shaft of a wiping baki in alternating rotation around the main axis of the wiper. tree.

- k figure 4 est une section de l'agencement représenté à k figure 3. [0022] Dans k description qui va suivre, des éléments identiques, simikires ou analogues seront désignés par les mêmes chiffres de référence. [0023] On a représenté aux figures 2 à 4 une extrémité 18 d'une barre 22 de k tringlerie 16 d'un système d'essuyage 10 qui est simikire au système d'essuyage 10 décrit précédemment, en référence à un mode de réalisation selon l'art antérieur. [0024] Ici, l'extrémité 18 de k barre 22 représentée est l'extrémité 18 de k bielle 22, et elle est montée articulée par rapport à l'extrémité libre 20a du levier 20. [0025] L'extrémité 18 de k barre 22 porte ainsi, un joint de rotule 36 de protection du doigtFigure 4 is a section of the arrangement shown in Figure 3. [0022] In the following description, identical, similar or similar elements will be designated by the same reference numerals. FIGS. 2 to 4 show an end 18 of a bar 22 of the linkage 16 of a wiper system 10 which is similar to the wiper system 10 described above, with reference to one embodiment according to the prior art. Here, the end 18 of k bar 22 shown is the end 18 of k connecting rod 22, and is articulated relative to the free end 20a of the lever 20. The end 18 of k 22 door bar as well, a ball joint 36 finger protection
26 et du logement 30 de k boîte à rotule 32. [0026] Cependant, il sera compris que l'invention n'est pas limitée au montage du joint de rotule 36 sur l'extrémité 18 de k bielle 22, et que l'invention concerne aussi le montage du joint de rotule 36 sur une autre barre de k tringlerie 16, comme par exemple sur le levier 20 ou sur k barre de liaison 24. [0027] La bielle 22 est ici réalisée par découpe et pliage d'une bande métallique. Ainsi, l'extrémité 18 de k bielle 22 est globalement pkne. [0028] L'extrémité 18 de k bielle 22 porte ainsi k boîte à rotule 32 qui est montée dans un orifice centeil 38 de l'extrémité 18 de k bielle 22. [0029] Comme on peut le voir plus en détail à k figure 4, k boîte à rotule 32 est montée dans l'orifice central 38 par moukge sur l'extrémité 18 de k bielle 22. [0030] Le joint de rotule 36 est monté sur l'extrémité 18 de k bielle 22 de manière qu'il comporte une première portion 40 formant un bourrelet annukire qui est agencée sur k face 18s de l'extrémité 18 de k bielle 22, qui est en vis-à-vis de l'extrémité 20a du levier 20 et qui est formée de manière qu'elle enveloppe le doigt 26 d'articuktion et de manière à pouvoir se déformer en fonction des déplacements rektifs de k bielle 22 par rapport au levier 20. [0031] Le joint de rotule 36 comporte aussi une portion 42 qui est agencée sur l'autre face26 and the housing 30 of k ball box 32. However, it will be understood that the invention is not limited to mounting the seal of ball 36 on the end 18 of k connecting rod 22, and that the invention also relates to the mounting of the ball joint 36 on another linkage bar 16, such as on the lever 20 or on the connecting bar 24. The rod 22 is here produced by cutting and folding a metal strip. Thus, the end 18 of k link 22 is globally pkne. The end 18 of k connecting rod 22 thus k ball box 32 which is mounted in a centeil hole 38 of the end 18 of k rod 22. As can be seen in more detail at k figure 4, k ball box 32 is mounted in the central hole 38 by mukge on the end 18 of k rod 22. The ball joint 36 is mounted on the end 18 of k connecting rod 22 so that it comprises a first portion 40 forming an annular bead which is arranged on the face 18s of the end 18 of k connecting rod 22, which is opposite the end 20a of the lever 20 and which is formed so that it envelops the finger 26 of articuktion and so as to be deformable according to the relative displacements of k rod 22 relative to the lever 20. [0031] The ball joint 36 also comprises a portion 42 which is arranged on the other face
18i de l'extrémité 18 de k bielle 22, et qui est reliée à k première portion 40, pour maintenir le bourrelet 36 sur l'extrémité 18 de k bielle 22. [0032] Conformément à l'invention, le joint de rotule 36 est réalisé par moukge d'une matière pkstique sur l'extrémité 18 de k bielle 22. [0033] Selon le mode de réalisation représenté aux figures, le joint de rotule 36 est moulé au travers de l'extrémité 18 de k bielle 22, c'est-à-dire que l'extrémité 18 de k bielle 22 comporte au moins un orifice 44 qui est tmversé par une portion du joint de rotule 36, pour relier k première portion 40 à k deuxième portion 42. [0034] Ici, l'extrémité 18 de k bielle 22 comporte une plumlité d'orifices 44 qui sont répartis de manière homogène autour de l'orifice central 38, en formant des arcs d'un cercle coaxial à l'orifice central 38. [0035] Selon une variante de réalisation non représentée, le joint de rotule 36 est réalisé par moukge autour de l'extrémité 18 de k bielle 22.
