Description

ESSUIE-GLACE EQUIPE D'UNE CALE DE MONTAGE  WIPER EQUIPPED WITH MOUNTING BRACKET
[0001 ] La présente invention concerne un essuie-glace équipé d'une cale de montage. The present invention relates to a windscreen wiper equipped with a mounting wedge.
[0002] La présente invention concerne plus particulièrement un essuie-glace de véhicule, notamment du type d'une automobile, comportant au moins un arbre mobile monté à rotation sur un palier associé, chaque arbre étant relié à un bras portant une raclette ainsi qu'à au moins une bielle de liaison à un mécanisme d'entraînement. The present invention relates more particularly to a vehicle wiper, including the type of a car, comprising at least one movable shaft rotatably mounted on an associated bearing, each shaft being connected to an arm carrying a squeegee as well as at least one connecting rod to a drive mechanism.
[0003] Un essuie-glace connu de véhicule comprend habituellement un motoréducteur formant un moyen d'entraînement relié mécaniquement à un arbre mobile en rotation autour d'un palier tandis que l'extrémité libre de chaque arbre est liée à rotation sur un bras portant une raclette. A known vehicle wiper usually comprises a geared motor forming a drive means mechanically connected to a rotating shaft about a bearing while the free end of each shaft is rotatably connected to a bearing arm a raclette.
[0004] Un tel essuie-glace est monté sur des supports dédiés de la structure du véhicule par l'intermédiaire de chacun de ses paliers, voire par l'intermédiaire d'une cale de montage reliée au moyen d'entraînement. Such a windscreen wiper is mounted on dedicated supports of the vehicle structure via each of its bearings, or even via a mounting block connected to the drive means.
[0005] La position angulaire de chaque arbre de rotation par rapport au palier au travers duquel il s'étend, a une incidence sur la course de la raclette sur le pare- brise, lorsque l'essuie-glace est dans un état de fonctionnement. Une telle position angulaire influe donc la qualité perçue qu'a le client du véhicule de sorte que la position de la raclette répond à des préconisations très précises émanant du constructeur. The angular position of each rotation shaft relative to the bearing through which it extends, affects the race of the squeegee on the windshield, when the wiper is in an operating state . Such an angular position therefore influences the perceived quality that the customer of the vehicle so that the position of the squeegee meets very specific recommendations from the manufacturer.
[0006] C'est la raison pour laquelle, après avoir monté le palier sur la structure du véhicule, on opère un réglage de la position angulaire de l'arbre de rotation sur lequel est fixée solidairement la raclette de l'essuie-glace de sorte que la raclette est positionnée par rapport à un marquage physique réalisé sur le pare-brise. This is the reason why, after mounting the bearing on the vehicle structure, it operates a setting of the angular position of the rotation shaft on which is fixed integrally the squeegee of the wiper of so that the squeegee is positioned relative to a physical marking made on the windshield.
[0007] Une telle opération augmente le temps de fabrication d'un véhicule, d'autant plus qu'un essuie-glace comporte bien souvent plusieurs raclettes. Il faut alors dupliquer l'opération de réglage pour chacune des raclettes. [0008] Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. Such an operation increases the manufacturing time of a vehicle, especially since a wiper often has several squeegees. It is then necessary to duplicate the adjustment operation for each of the scrapers. An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
[0009] A cette fin, l'essuie-glace selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que le palier comprend un moyen d'immobilisation de l'arbre sur celui-ci, dans une position angulaire prédéterminée. To this end, the windscreen wiper according to the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the bearing comprises a means of immobilizing the shaft thereon in a predetermined angular position.
[0010] Un tel essuie-glace permet de réduire le temps de fabrication du véhicule puisque l'opération traditionnellement allouée au réglage de la position angulaire de chaque bras portant une raclette n'est plus utile. En effet, la conception de l'essuie- glace permet de figer la position angulaire de chaque arbre de rotation par rapport au palier de sorte que le montage de chaque palier d'essuie-glace sur la structure du véhicule, permet de positionner correctement l'axe de rotation par rapport à la structure du véhicule, par conséquent la raclette par rapport au pare-brise, sans avoir recours une quelconque opération de réglage. [001 1 ] Par ailleurs, l'essuie-glace de l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes : ledit moyen d'immobilisation comprend au moins une cale de montage reliée au palier, ce qui permet une fabrication simple et peu coûteuse. ledit moyen d'immobilisation comprend deux cale de montages disposées l'une au regard de l'autre, lesdites cales de montages bloquant en rotation la manivelle dans une position angulaire prédéterminée par rapport au palier, ce qui permet de créer une liaison sans jeu angulaire entre le palier et l'arbre destiné à recevoir le bras portant une raclette, améliorant d'autant la précision du positionnement angulaire de l'axe de rotation sur la structure du véhicule, par conséquent de la raclette sur le pare-brise, l'essuie-glace comprend deux manivelles reliées entre elles et montées chacune à rotation sur un palier associé par l'intermédiaire d'un arbre de rotation et en ce que ledit moyen d'immobilisation comprenant deux cales de montages reliées chacune à un palier, l'une des cales de montages étant destinée à former une butée au pivotement d'une des manivelles dans un sens, l'autre des cales de montages étant destinée à former une butée au pivotement de l'autre des manivelles dans un sens contraire, une telle immobilisation partielle de chaque manivelle dans un sens donné permet d'obtenir à moindre coût une précision quant à la position relative de chaque raclette sur le pare-brise. En outre l'assemblage des manivelles entre elles combiné à une telle immobilisation partielle assure l'immobilisation générale de chaque arbre de rotation dans une position angulaire. chaque cale de montage s'étend tangentiellement en saillie hors d'un palier, ce qui facilite la modification des palier d'essuie-glace traditionnellement utilisés sur les véhicules, tout en maîtrisant les coûts de développement pour améliorer la qualité perçue par le client du véhicule. la cale de montage est reliée au palier par un pion s'étendant radialement au palier et perpendiculairement à la cale de montage, ce qui permet un changement de matière entre le palier, la cale et le moyen liant le palier à la cale afin de répondre de façon la plus appropriée aux exigences de rigidité de la pièce, comme cela est par exemple le cas pour le palier ou la cale, mais aussi de déformation, comme cela est par exemple le cas pour le pion. chaque palier et tout ou partie dudit moyen d'immobilisation forment une pièce réalisée d'un seul tenant par surmoulage dudit moyen d'immobilisation sur le palier, ce qui reste une manière simple et peu onéreuse de fabrication de l'essuie-glace. - le pion ou le palier comprend une zone de rupture prédéterminée rendant apte la désolidarisation opérable soit manuellement, soit lors de la première mise en fonctionnement dudit mécanisme d'entraînement, du pion d'avec le palier, ce qui permet de rendre facilement opérationnelle le fonctionnement de l'essuie-glace malgré la présence de la cale de montage. - chaque palier et ledit moyen d'immobilisation sont des pièces distinctes assemblées l'une sur l'autre de manière démontable, ce qui rend la cale recyclable, voire réutilisable sur d'autres essuie-glaces. la cale de montage comprend un moyen de préhension définit par une zone à reliefs, ce qui facilite sa désolidarisation avec le palier, qu'il s'agisse d'une rupture ou d'un démontage de la cale pour libérer la rotation de l'arbre sur le palier associé. [0012] D'autres avantages et particularités de l'invention ressortent de la description de modes de réalisation faite ci-après en référence aux dessins annexés dans lesquels : Such a wiper reduces the manufacturing time of the vehicle since the operation traditionally allocated to adjusting the angular position of each arm carrying a squeegee is no longer useful. Indeed, the design of the windshield wiper makes it possible to fix the angular position of each rotation shaft relative to the bearing so that the mounting of each wiper bearing on the structure of the vehicle makes it possible to position the windscreen wiper correctly. axis of rotation relative to the vehicle structure, therefore the squeegee relative to the windshield, without resorting any adjustment operation. [001 1] Moreover, the wiper of the invention may comprise one or more of the following features: said immobilizing means comprises at least one mounting wedge connected to the bearing, which allows a simple manufacture and inexpensive. said immobilizing means comprises two shims arranged in relation to each other, said shims blocking in rotation the crank in a predetermined angular position relative to the bearing, which allows to create a connection without backlash between the bearing and the shaft for receiving the arm carrying a squeegee, thereby improving the accuracy of the angular positioning of the axis of rotation on the vehicle structure, therefore the squeegee on the windshield, the windscreen wiper comprises two cranks interconnected and each rotatably mounted on an associated bearing via a rotation shaft and in that said immobilizing means comprising two shims each connected to a bearing, the one of the shims being intended to form a stop pivoting of one of the cranks in one direction, the other of the shims of montages being intended to form an abutment to pivot the other of the cranks in a contrary direction, such partial immobilization of each crank in a given direction makes it possible to obtain at a lower cost a precision as to the relative position of each scraper on the windshield -broken. In addition the assembly of the cranks together combined with such partial immobilization ensures the general immobilization of each rotation shaft in an angular position. each mounting block extends tangentially projecting out of a bearing, which facilitates the modification of wiper bearings traditionally used on vehicles, while controlling development costs to improve the quality perceived by the customer of the vehicle. the mounting block is connected to the bearing by a pin extending radially from the bearing and perpendicular to the mounting block, which allows a change of material between the bearing, the shim and the means connecting the bearing to the shim to meet most suitably to the requirements of rigidity of the part, as is the case for example for the bearing or the wedge, but also deformation, as is the case for example for the pawn. each bearing and all or part of said immobilizing means form a part made in one piece by overmolding said immobilizing means on the bearing, which remains a simple and inexpensive way of manufacturing the wiper. - The pin or the bearing comprises a predetermined breaking zone making it suitable for the disconnection operable either manually or during the first operation of said drive mechanism, the pin with the bearing, which makes it easy to operate the operation of the wiper despite the presence of the mounting wedge. - Each bearing and said immobilizing means are separate parts assembled on one another in a removable manner, which makes the shim recyclable, or reusable on other windshield wipers. the mounting wedge comprises a gripping means defined by a relief zone, which facilitates its separation from the bearing, whether it is a break or a disassembly of the wedge to release the rotation of the tree on the associated landing. Other advantages and features of the invention emerge from the description of embodiments given below with reference to the accompanying drawings in which:
- la figure 1 est une vue en perspective d'une partie d'un essuie-glace pris isolément représenté dans un état de fonctionnement normal, selon l'invention, FIG. 1 is a perspective view of a portion of a wiper taken alone represented in a normal operating state, according to the invention,
- la figure 2 est une vue en perspective agrandissant la zone D de la figure 1 où sont représentés un palier, une bielle de liaison et des cales de montage, selon l'invention, FIG. 2 is a perspective view enlarging zone D of FIG. 1, showing a bearing, a connecting rod and mounting shims, according to the invention,
- la figure 3 est une représentation en perspective d'une cale de montage de la figure 2, prise isolément, selon l'invention. - Figure 3 is a perspective representation of a mounting block of Figure 2, taken separately, according to the invention.
[0013] En se reportant à la figure 1 , l'essuie-glace 1 est représenté dans sa version prête au montage sur la structure du véhicule, c'est-à-dire dépourvu des bras portant les raclettes venant en appui sur le pare-brise du véhicule. Referring to Figure 1, the windscreen wiper 1 is shown in its version ready for mounting on the vehicle structure, that is to say without arms bearing squeegee bearing on the bumper -brise vehicle.
[0014] Bien entendu, sans sortir du cadre de l'invention, l'essuie-glace est destiné à recevoir une seule raclette qui est conformée pour une utilisation sur une lunette arrière par exemple. Of course, without departing from the scope of the invention, the wiper is intended to receive a single squeegee which is shaped for use on a rear window, for example.
[0015] Comme cela est représenté sur la figure 1 , l'essuie-glace 1 comprend un motoréducteur 5, formant un moyen d'entraînement des raclettes, qui est rendu solidaire d'une plaque de support définissant un pied 21 arrière et deux oreilles 22 situées à l'opposé du pied 21 . As shown in Figure 1, the wiper 1 comprises a geared motor 5, forming a squeegee drive means, which is secured to a support plate defining a rear leg 21 and two ears 22 located opposite the foot 21.
[0016] L'essuie-glace comprend des arbres 2 disposés à l'intérieur de paliers 3. Chaque palier 3 est apte à être fixé de manière solidaire à la structure. Ils comprennent à cet effet une plaque de support formant une collerette 23 s'étendant radialement hors du corps principal du palier 3. [0017] Chaque collerette 23 et oreilles 22 comprennent des ouvertures destinées à recevoir une vis de fixation pour leur serrage contre une pièce de structure du véhicule. [0018] Le pied 21 arrière est chaussé par un élément de réduction de vibration, du type d'une gaine en caoutchouc, destiné à être emmanché en force dans un logement pratiqué dans la structure du véhicule. The wiper comprises shafts 2 disposed within bearings 3. Each bearing 3 is adapted to be fixed integrally to the structure. They comprise for this purpose a support plate forming a collar 23 extending radially out of the main body of the bearing 3. Each collar 23 and lugs 22 comprise openings intended to receive a fixing screw for their clamping against a workpiece of vehicle structure. The rear foot 21 is shod by a vibration reduction element, of the type of a rubber sheath, intended to be force-fitted into a housing made in the vehicle structure.
[0019] Les arbres 2 comprennent une extrémité libre sur laquelle un bras (non représenté) portant une raclette est fixé à rotation de sorte que la rotation de l'arbre engendre le déplacement de la raclette. The shafts 2 comprise a free end on which an arm (not shown) carrying a squeegee is fixed to rotate so that the rotation of the shaft causes the movement of the squeegee.
[0020] L'autre extrémité de l'arbre 2 est fixée à rotation à une manivelle 4. The other end of the shaft 2 is rotatably attached to a crank 4.
[0021 ] Les manivelles 4 sont reliées entre elles au moyen de bielles 14 selon une liaison pivot située au niveau de leurs extrémités libres. [0022] L'autre extrémité libre de chaque bielle 14 est reliée à l'arbre de sortie du motoréducteur par l'intermédiaire d'une manivelle (non représentée) montée solidaire à rotation dudit arbre de sortie. The cranks 4 are interconnected by means of connecting rods 14 in a pivot connection located at their free ends. The other free end of each connecting rod 14 is connected to the output shaft of the geared motor by means of a crank (not shown) mounted integral with rotation of said output shaft.
[0023] Le palier de l'essuie-glace comprend un moyen d'immobilisation de l'arbre sur le palier, dans une position angulaire prédéterminée. Un tel moyen d'immobilisation a volontairement été omis de la figure 1 pour la rendre plus claire. The bearing of the wiper comprises a means for immobilizing the shaft on the bearing, in a predetermined angular position. Such immobilization means has deliberately been omitted from FIG. 1 to make it clearer.
[0024] Toutefois, comme cela est représenté sur la figure 2, qui est un agrandissement de l'une des zones encerclées par des traits en pointillés de la figure 1 , portant en outre le repère général D, le palier 3 comprend un moyen 6 d'immobilisation. [0025] Dans ce qui suit, seulement un palier 3 sera décrit, sachant que selon les cas, l'autre palier de l'essuie-glace est conformé sensiblement à l'identique, à ceci près que la symétrie et position angulaire prédéterminée de la manivelle 4 par rapport au palier impliquent un autre positionnement dudit moyen 6 d'immobilisation sur le palier. [0026] Ledit moyen 6 d'immobilisation comprend au moins une cale 8 de montage. However, as shown in Figure 2, which is an enlargement of one of the areas encircled by dashed lines of Figure 1, further bearing the general reference D, the bearing 3 comprises a means 6 immobilization. In what follows, only a bearing 3 will be described, knowing that depending on the case, the other bearing of the wiper is shaped substantially identical, except that the symmetry and predetermined angular position of the crank 4 relative to the bearing imply another positioning of said immobilization means 6 on the bearing. Said immobilizing means 6 comprises at least one mounting shim 8.
[0027] La figure 2 représente un mode de réalisation préférée de l'invention, où chaque palier 3 est relié à un moyen 6 d'immobilisation qui comprend plusieurs cales 8 de montage. [0028] Plus particulièrement, les cales 8 de montage sont au nombre de deux, et disposées l'une au regard de l'autre, de façon sensiblement tangentielle au palier 3. [0027] Figure 2 shows a preferred embodiment of the invention, wherein each bearing 3 is connected to a means 6 of immobilization which comprises several mounting wedges 8. More particularly, the shims 8 of mounting are two in number, and arranged with respect to each other, substantially tangentially to the bearing 3.
[0029] L'écart entre les cales 8 de montage est sensiblement égal à la largeur de la manivelle 4 de sorte que celle-ci est bloquée en rotation dans une position angulaire prédéterminée par rapport au palier 3. C'est ainsi que la position des cales 8 de montage sur le palier 3 définissent la position de la manivelle 4, donc de l'arbre auquel elle est fixée, par rapport au palier 3. The distance between the shims 8 of assembly is substantially equal to the width of the crank 4 so that it is locked in rotation in a predetermined angular position relative to the bearing 3. This is how the position shims 8 for mounting on the bearing 3 define the position of the crank 4, therefore of the shaft to which it is fixed, relative to the bearing 3.
[0030] Selon un autre mode de réalisation non représenté, ledit moyen d'immobilisation comprenant deux cales 8 de montages reliées chacune à un palier 3. Ainsi, l'une des cales 8 de montages définit une butée au pivotement de la manivelle associée, dans un sens. L'autre des cales 8 de montages, qui est reliée à l'autre palier 3, définit une butée au pivotement de la manivelle 4 associée dans un sens contraire. According to another embodiment not shown, said immobilizing means comprising two shims 8 assemblies each connected to a bearing 3. Thus, one of the shims 8 assemblies defines a stop pivoting of the associated crank, in a sense. The other of the shims 8 of assemblies, which is connected to the other bearing 3, defines a stop pivoting of the associated crank 4 in a contrary direction.
[0031 ] La liaison des manivelles entre elles, opérée par un jeu de bielles 14, rend apte un blocage en rotation de chaque manivelle 4 par rapport au palier 3 associé, dans une position angulaire prédéterminée. The connection of the cranks to one another, operated by a set of connecting rods 14, makes it possible to block rotation of each crank 4 with respect to the associated bearing 3, in a predetermined angular position.
[0032] La hauteur de chaque cale 8 de montage est supérieure à l'épaisseur de chaque manivelle 4 de sorte que la surépaisseur relative définit un moyen de préhension qui est rendue facilement accessible. La cale 8 de montage s'étend ainsi en saillie verticale hors de la manivelle 4 de sorte qu'il est rendu possible un accès en aveugle à chaque cale 8 de montage en suivant la manivelle 4. The height of each shim 8 mounting is greater than the thickness of each crank 4 so that the relative allowance defines a gripping means which is made easily accessible. The mounting shim 8 thus extends in vertical projection out of the crank 4 so that blind access to each shim 8 of assembly is made possible by following the crank 4.
[0033] La liaison entre chaque cale 8 et le palier 3 est réalisée par l'intermédiaire d'un pion 7 s'étendant radialement au palier 3 et perpendiculairement à la cale 8 de montage, comme cela est représenté sur la figure 3. [0034] L'essuie-glace 1 est dans une version apte à son fonctionnement dépourvu de toute cale 8 de montage. C'est pour cela que la cale 8 est reliée au palier 3 par un pion 7 approprié pour désolidariser la cale du palier. The connection between each shim 8 and the bearing 3 is formed by means of a pin 7 extending radially to the bearing 3 and perpendicular to the shim 8 of assembly, as shown in Figure 3. [ 0034] The windscreen wiper 1 is in a version capable of functioning without any shim 8 of assembly. This is why the shim 8 is connected to the bearing 3 by a pin 7 suitable for separating the wedge from the bearing.
[0035] Le pion 7 fait saillie hors de la face de la cale 8 de montage orientée vers le bord 10 de la manivelle 4. Le pion 7 est une tige sensiblement cylindrique venue de matière avec la cale 8, voire une pièce rapportée. [0036] De préférence, le pion 7 et la cale 8 sont une même pièce obtenue, par exemple par un moulage d'une matière plastique. The pin 7 protrudes from the face of the mounting shim 8 oriented towards the edge 10 of the crank 4. The pin 7 is a substantially cylindrical rod integral with the shim 8, or an insert. Preferably, the pin 7 and the shim 8 are a single piece obtained, for example by a molding of a plastic material.
[0037] Le pion 7 est emmanché en force dans un trou de forme complémentaire réalisé à cet effet dans le palier 3. [0038] Selon une variante de réalisation, le pion 7 est surmoulé sur le palier 3. La désolidarisation entre toute cale 8 et un palier 3 est réalisée par cisaillement du pion 7. En outre, le pion 7 comprend une zone de rupture programmée, définit pour rompre la liaison sous l'effet prédéfini. The pin 7 is force-fitted into a hole of complementary shape made for this purpose in the bearing 3. According to an alternative embodiment, the pin 7 is overmolded on the bearing 3. The separation between any shim 8 and a bearing 3 is made by shearing the pin 7. In addition, the pin 7 comprises a programmed breaking zone, defined to break the connection under the predefined effect.
[0039] De manière avantageuse, le pion 7 est apte à se déformer jusqu'à sa rupture, ce qui rend possible soit la mise au rebut de la cale 8, soit le recyclage de celle-ci pour la fabrication d'une nouvelle cale. Advantageously, the pin 7 is able to deform until it breaks, which makes possible either the scrapping of the shim 8 or the recycling thereof for the manufacture of a new shim .
[0040] Le pion 7 est ainsi apte à se rompre sous l'effet d'un effort de rupture qui est soit issu de la main d'un opérateur, soit issu d'un couple de rotation de la manivelle 4 autour du palier 3, lors de la première mise en fonctionnement du motoréducteur 5. [0041 ] Dans le but de rendre plus aisé l'opération manuelle de désolidarisation de la cale 8 de montage hors de l'essuie-glace 1 , la partie de la cale 8 disposée verticalement en saillie hors de la manivelle 4, formant ledit moyen 9 de préhension de la cale, comprend une zone à reliefs augmentant localement le coefficient d'adhérence de la cale pour le doigt d'un opérateur, ce qui permet une prise améliorée et par voie de conséquence une rupture facilité du pion 7. The pin 7 is thus able to break under the effect of a breaking force that is either from the hand of an operator, or from a torque of rotation of the crank 4 around the bearing 3 when the gearmotor 5 is first put into operation. [0041] In order to make it easier to manually disengage the shim 8 from the wiper 1, the portion of the shim 8 disposed vertically protruding out of the crank 4, forming said means 9 for gripping the wedge, comprises a relief zone locally increasing the coefficient of adhesion of the wedge for the finger of an operator, which allows an improved grip and by a consequence of an easy break of the pawn 7.
[0042] Selon une autre variante de réalisation, le pion 7 est une tige filetée destinée à venir en prise avec un trou taraudé pratiqué dans le palier 3 de sorte que toute cale 8 est rendue facilement démontable par dévissage et réutilisable par vissage sur un palier 3 d'un autre essuie-glace. [0043] L'essuie-glace 1 équipé d'une telle cale 8 de montage réduit le temps de fabrication du véhicule et implique le fabricant dans le respecter les recommandations du constructeur de véhicule en ce qui concerne la position relative de la raclette par rapport au pare-brise du véhicule. According to another embodiment, the pin 7 is a threaded rod intended to engage with a threaded hole made in the bearing 3 so that any wedge 8 is made easily removable by unscrewing and reusable by screwing on a bearing 3 of another windshield wiper. The windscreen wiper 1 equipped with such a mounting wedge 8 reduces the vehicle manufacturing time and involves the manufacturer in the respect the recommendations of the vehicle manufacturer with respect to the relative position of the squeegee relative to to the windshield of the vehicle.
