Abstract
Description
L'invention a pour objet un dispositif de nettoyage de glaces de véhicules automobiles, comportant un groupe pour déplacer en mouvement pendulaire au moins un arbre relié à un essuie-glace, une pompe pour refouler du liquide de lavage d'un réservoir à l'une des embouchures d'un perçage lofai gitudinal pratiqué dans l'arbre, l'autre embouchure de ce per- çage étant reliée à une buse de projection dont l'orifice de projection est dirigé vers la glace à nettoyer. The subject of the invention is a motor vehicle window cleaning device, comprising a group for moving in pendular movement at least one shaft connected to a windscreen wiper, a pump for delivering washing liquid from a tank to the one of the mouths of a longitudinal lofai hole made in the tree, the other mouth of this hole being connected to a projection nozzle whose projection orifice is directed towards the glass to be cleaned.
On connaît déjà un dispositif de ce ty- pe dans lequel une conduite de refoulement flexihle provenant de la pompe de refoulement est assemblée rigidement avec lwarbre
La conduite de refoulement doit donc, pendant le fonctionnement du dispositif, partieiper au mouvement pendulaire de l'arbres ce qui exige un certain volume libre pour que la conduite, r61 lativement molle, ne soit pas endommagée. Dans le cas des conduites plus robustes, le risque existe d'une rupture de conduit par fatigue.A device of this type is already known in which a flexible delivery line coming from the delivery pump is rigidly assembled with the shaft.
The discharge line must therefore, during operation of the device, be part of the pendulum movement of the shafts, which requires a certain free volume so that the line, which is laterally soft, is not damaged. In the case of more robust pipes, the risk exists of a pipe break by fatigue.
L'invention a pour but d'éviter les in- convénients mentionnés précédemment et concerne à cet effet un dispositif du type ci-dessus caractérisé en ce que l'extrémité de l'arbre présentant la première embouchure pénètre dans wa ment en forme de pot reposant par une collerette sur une paroi traversée par l'arbre, le bout de l'arbre dans le pot étant espacé du fond de pot, et en ce qu'une conduite de refoulement la pompe débouche dans le volume qui se trouve entre la face de bout et le fond du pot. The object of the invention is to avoid the drawbacks mentioned above and to this end relates to a device of the above type, characterized in that the end of the shaft having the first mouth penetrates into a pot-like shape. resting by a flange on a wall traversed by the tree, the end of the tree in the pot being spaced from the bottom of the pot, and in that a discharge line the pump opens into the volume which is located between the face end and the bottom of the pot.
Par rapport aux réalisations connus, le dispositif de nettoyage conforme à liinvention a pour avaa- ge que la conduite de refoulement est assemblée avec un élément de construction solidaire du chamois. Cette conduite peut donc être déterminée sans tenir compte de l'angle du mouvement pen; dulaire de l'arbre. Le passage du liquide de lavage de l'él4Don1 de construction solidaire du châssis à l'arbre pendulaire a par l'intermédiaire du volume situé entre la face de bout de 1' arbre et le fond du pot. Compared with known embodiments, the cleaning device according to the invention has the advantage that the discharge pipe is assembled with a construction element integral with the chamois. This conduct can therefore be determined without taking into account the angle of the pen movement; dular of the tree. The passage of the washing liquid from the el4Don1 of construction integral with the chassis to the pendular shaft has via the volume situated between the end face of the shaft and the bottom of the pot.
Des dispositions indiquées dans la eni te penmettent d'obtenir des modes de réalisation avantageux ét des perfectionnements du dispositif de nettoyage conforme à I, invention. Provisions indicated in the eni allow you to obtain advantageous embodiments and improvements of the cleaning device according to I, invention.
L'invention est décrite ci-après avec référence aux dessins annexes représentant un exemple de réalisation , dessins dans lesquels:
-la figure 1 est une vue de dessus d' un groupe de commande mettant un essuis-glace en mouvement;
-la figure 2 est une vue en coupe effectuée suivant la ligne II-II de la figure 1;
-la figure 3 est une vue à plus grande échelle d'un détail désigné par III sur la figure 2.The invention is described below with reference to the accompanying drawings representing an exemplary embodiment, drawings in which:
FIG 1 is a top view of a control group putting a wiper in motion;
FIG 2 is a sectional view taken along line II-II of Figure 1;
FIG. 3 is a view on a larger scale of a detail designated by III in FIG. 2.
Ce dispositif de nettoyage de glaces de véhicules automobiles, représenté schématiquement sur la figure 1, comporte un groupe de commande 10 constitué par un moteur électrique et un mécanisme pendulaire associé à ce moteur. Un arbre d'essuie-glace 12 est monté pour tourner dans le groupe de commande 10 (figure 2) , un essuie-glace étant calé à l'ex- trémité non représentée de cet arbre. L'essuie-glace repose sur le pare-brise,(non représenté), d'un véhicule automobile et il a pour tâche de maintenir exempt d'encrassement, par le mouvement pendulaire provoqué par l'arbre d'essuie-glace 12, le chainp visuel du chauffeur du véhicule automobile. This motor vehicle window cleaning device, shown diagrammatically in FIG. 1, comprises a control group 10 constituted by an electric motor and a pendulum mechanism associated with this motor. A wiper shaft 12 is mounted for rotation in the control group 10 (FIG. 2), a wiper being wedged at the end, not shown, of this shaft. The wiper rests on the windshield, (not shown), of a motor vehicle and its task is to keep it free from fouling, by the pendulum movement caused by the wiper shaft 12, the visual chain of the driver of the motor vehicle.
Le groupe de commande 10 est disposé dans un carter dont une paroi 14 est traversée par l'extrémité 16, représentée sur la figure 2, de l'arbre d'essuie glace 12
L'extrémité 16 de l'arbre d'essuie-glace 12 pénètre dans un élément de construction en forme de pot 18 fixé de façon étanche sur la paroi 14 par une collerette de bordure 20. L'élément de construction 18 est en matière plastique et est, de préférence, moulé par injection sur la paroi 14, enclenché dans cette paroi 14 ou assemblé avec elle par rivetage. Le fond 22 de l'élément de construction 18 en forme de pot se trouve à une certaine distance de la face de bout 24, dirigée yers lui, de l'arbre d' essuie-glace 12. Un volume cylindrique 26 est ainsi ménagé entre la face de bout 24 et le fond 22 du pot.The control group 10 is disposed in a casing, one wall 14 of which is crossed by the end 16, shown in FIG. 2, of the wiper shaft 12
The end 16 of the wiper shaft 12 enters a pot-shaped construction element 18 fixed in a sealed manner to the wall 14 by an edge flange 20. The construction element 18 is made of plastic and is preferably injection molded on the wall 14, engaged in this wall 14 or assembled with it by riveting. The bottom 22 of the pot-shaped building element 18 is located at a certain distance from the end face 24, directed yers him, of the wiper shaft 12. A cylindrical volume 26 is thus formed between the end face 24 and the bottom 22 of the pot.
Dans ce volume 26 débouche une conduite d'amenée 30 disposée dans une tubulure de raccord 28 formée sur l'élément de construction 18. Dans l'exemple de réalisation considéré, la tubulure de raccord 28 est disposée radialement par rapport au volume 26. Mais on peut aussi envisager de former cette tubulure sur la paroi du fond de l'élément de construction en forme de pot 18, de telle sorte que la conduite d'amenée est disposée dans la direction de l'axe de arbre deetssuie glace 12. In this volume 26 opens a supply pipe 30 disposed in a connection tube 28 formed on the construction element 18. In the embodiment considered, the connection tube 28 is arranged radially relative to the volume 26. But it is also conceivable to form this tubing on the bottom wall of the pot-shaped building element 18, so that the supply line is arranged in the direction of the axis of the shaft 12.
Dans l'arbre d'essuie-glace 12 est pratiqué un perçage longitudinal axial 32 dont une embouchure 34 aboutit dans le volume 26. A l'autre embouchure, non repré- sentée, du perçage longitudinal axial 32 est raccordée une cot duite non représentée qui va à la base de projection, qui n'est pas représentée non plus, l'orifice de projection de cette base étant dirigé vers ia glace à nettoyer.Pour obtenir une étanchéité correcte entre la paroi latérale 36 de l'élément de construction 18 et l'arbre d'essuie-glace 12, l'extrémité 16 de cet arbre 12 est munie dans sa surface latérale d'une rainure annu laire 38 dans laquelle est insérée une bague torique 40 as sur rant l'étanchéité du volume cylindrique 26 vis-à-vis de l'ex- térieur. Le passage, par lequel l'arbre d'essuie-glace 12 sr6- verse la paroi 14 présente un diantre un peu plus grand que celui de 1'arbre. On a ainsi la place pour disposer un joint d étanchéité 42 (figure 3) qui repose par deux livres d'étanché- ité 44, 46 sur la surface latérale de l'arbre d'essuie-glace 12. In the wiper shaft 12 is made an axial longitudinal bore 32, a mouth 34 terminates in the volume 26. The other mouth, not shown, of the axial longitudinal bore 32 is connected a not shown cot which goes to the projection base, which is not shown either, the projection orifice of this base being directed towards the glass to be cleaned. To obtain a correct seal between the side wall 36 of the building element 18 and the wiper shaft 12, the end 16 of this shaft 12 is provided in its lateral surface with an annular groove 38 in which is inserted an O-ring 40 as on the tightness of the cylindrical volume 26 vis-à-vis the exterior. The passage through which the wiper shaft 12 flows through the wall 14 has a slightly larger diameter than that of the shaft. There is thus room to have a seal 42 (FIG. 3) which rests by two sealing books 44, 46 on the lateral surface of the wiper shaft 12.
Etant donné que la lèvre d'étanchéité 46 du joint d'étanchéité 42 est disposée à une certaine distan- ce de la bague torique 40, une place est ménagée pour un volume annulaire 48 présentant plusieurs orifices 50, de préférence quatre orifices, répartis sur le pourtour du bord annulaire. Since the sealing lip 46 of the seal 42 is disposed at a certain distance from the O-ring 40, a place is provided for an annular volume 48 having several orifices 50, preferably four orifices, distributed over the periphery of the annular edge.
Comme on le voit sur la figure 1, une xronduite de refoulement 52 est raccordée à la tubulure de raccord 28 de l'élément de construction 18. Cette conduite est reliée à une pompe de refoulement 54. La conduite de refoulement 52 est munie d'une tubulure re d'aspiration 56 qui plonge dans un réservoir 58 dans lequel se trouve du liquide de lavage.As can be seen in FIG. 1, a discharge pipe 52 is connected to the connection pipe 28 of the building element 18. This pipe is connected to a delivery pump 54. The delivery pipe 52 is provided with a suction tube 56 which plunges into a reservoir 58 in which there is washing liquid.
Lors de son fonctionnement, la pompe 54 refoule par la conduite de refoulement 52 et la conduite d' amenée 30 du liquide de lavage dans le volume cylindrique 26 de l'élément de construction en forme de pot 18. A partir de là, le liquide de lavage est envoyé dansSl'arbre d'essuie-glace 12 par l'embouchure 34 du perçage longitudinal axial 32. Le liquide est ensuite envoyé à la buse de projection et, de là, à la gla ce à nettoyer. During its operation, the pump 54 delivers via the delivery line 52 and the supply line 30 for washing liquid into the cylindrical volume 26 of the pot-shaped building element 18. From there, the liquid The washing fluid is sent to the wiper shaft 12 through the mouth 34 of the axial longitudinal bore 32. The liquid is then sent to the spray nozzle and, from there, to the ice to be cleaned.
A la longue, il peut arriver qu'une
faible quantité de liquide de lavage franchisse la bague tori que 40. La pénétration de ce liquide dans le groupe de commande est cependant empêchée par la levre d'étanchéité 46 du joint d'étanchéité 42. Cette faible quantité de liquide s'accumule dans le volume annulaire 48 d'où elle est évacuée par l'un des orifices 50. La lèvre d'étanchéité 44 du joint d'étanchéité 42 empêche la sortie du lubrifiant du volume intérieur du groupe de commande. In the long run, it may happen that a
small amount of washing liquid crosses the tori ring 40. The penetration of this liquid into the control unit is however prevented by the sealing lever 46 of the seal 42. This small amount of liquid accumulates in the annular volume 48 from which it is discharged through one of the orifices 50. The sealing lip 44 of the seal 42 prevents the lubricant from leaving the interior volume of the control group.
