Description
Dispositif d'essuyage de vitre d'automobile à entraînement pendulaire du bras portant le balai
Etat de la technique.Automobile window wiping device with pendulum drive of the arm carrying the brush
State of the art.
L'invention concerne un dispositif d'essuyage pour les glaces d'un véhicule automobile, comportant un bras portant le balai dessuie-glace entraîné suivant un mouvement pendulaire sur la glace et dont le segment d'extrémité opposé à celui du balai est relié à la carrosserie du véhicule par un articulé, le quadrilatère articulé ayant deux leviers oscillants montés sur la carrosserie de manière fixe à chaque extrémité et dont l'autre extrémité est reliée de manière articulée au segment d'extrémité du bras d'essuyage. The invention relates to a wiping device for the windows of a motor vehicle, comprising an arm carrying the wiper blade driven in a pendular movement on the glass and the end segment of which opposite to that of the blade is connected to the vehicle body by an articulated, the articulated quadrilateral having two oscillating levers mounted on the body in a fixed manner at each end and the other end of which is connected in an articulated manner to the end segment of the wiper arm.
On connaît déjà un dispositif d'essuyage dont les deux leviers oscillants sont chaque fois guidés dans deux paliers fixes. Le fonctionnement de ce dispositif d'essuyage peut engendrer des bruits gênants transmis par les paliers à la tringlerie et ainsi à la carrosserie du véhicule et que l'on ne peut éviter qu'au prix d'une fabrication plus coûteuse ou par des interventions ultérieures. A wiping device is already known, the two oscillating levers of which are each guided in two fixed bearings. The operation of this wiping device can generate annoying noises transmitted by the bearings to the linkage and thus to the vehicle body and which can only be avoided at the cost of more expensive manufacturing or by subsequent interventions. .
A cet effet l'invention concerne un dispositif d'essuyage caractérisé en ce qu'au moins l'un des quatre paliers comporte des éléments amortisseurs élastiques portant un élément de palier pour un tourillon de palier et permettant un échappement essentiellement radial de l'élément de palier dans le bras d'essuyage. To this end the invention relates to a wiping device characterized in that at least one of the four bearings comprises elastic damping elements carrying a bearing element for a bearing journal and allowing an essentially radial escape of the element bearing in the wiper arm.
Le dispositif d'essuyage selon l'invention offre l'avantage d'assurer, grâce au palier souple recevant le levier oscillant, nécessairement un fonctionnement calme sans bruit, et cela sans nécessiter la mise en oeuvre de moyens supplémentaires. The wiping device according to the invention offers the advantage of ensuring, thanks to the flexible bearing receiving the oscillating lever, necessarily quiet operation without noise, and this without requiring the implementation of additional means.
Suivant d'autres caractéristiques intéressantes
- les éléments amortisseurs élastiques sont prévus sur au moins l'un des paliers, reliant le bras oscillant au segment d'extrémité du bras d'essuyage.According to other interesting characteristics

Description de l'exemple de réalisation.Description of the exemplary embodiment.
Un pare-brise 10 représenté à la figure 1 d'un véhicule automobile non détaillé est équipé de deux dispositifs d'essuyage 12, 14 traitant chacun un champ d'essuyage 16, 18. Le champ d'essuyage 18 traité par le dispositif d'essuyage 14 a une forme de segment de cercle. A windshield 10 shown in FIG. 1 of a non-detailed motor vehicle is equipped with two wiping devices 12, 14 each treating a wiping field 16, 18. The wiping field 18 treated by the device d wiping 14 has the shape of a circle segment.
Le dispositif d'essuyage 12 balaye par contre un champ 16 dont la forme est différente de celle d'un segment de cer cle. Le dispositif d'essuyage 12 fait l'objet des explications ci-après. Le dispositif d'essuyage 12 est un dispositif d'essuyage appelé dispositif pendulaire comprenant un bras d'essuyage 20. Ce bras porte à son extrémité un balai d'essuyage 22 appliqué contre la glace 10 à nettoyer. Le montage du bras d'essuyage 20 sur la carrosserie du véhicule se fait par l'intermédiaire d'un quadrilatère articulé.On the other hand, the wiping device 12 scans a field 16 whose shape is different from that of a ring segment. The wiping device 12 is the subject of the explanations below. The wiping device 12 is a wiping device called a pendulum device comprising a wiping arm 20. This arm carries at its end a wiping blade 22 applied against the glass 10 to be cleaned. The mounting of the wiper arm 20 on the vehicle body is done by means of an articulated quadrilateral.
Le quadrilatère articulé se compose de deux bras oscillants 24 et 26 dont une extrémité est montée de manière pendulaire sur des paliers 28, 30.solidaires du bâti ou de la carrosserie. L'autre extrémité des bras oscillants 24, 26 est reliée de manière articulée par des paliers 32 et 34 au bras d'essuyage. Grâce au quadrilatère articulé 28-34, le balai exécute un mouvement d'essuyage sur la vitre 10 qui diffère d'une forme de segment de cercle car le mouvement pendulaire est combiné à un mouvement de translation engendré par le quadrilatère articulé. Cela permet au champ d'essuyage 16 du balai 22 de mieux nettoyer un coin portant la référence 36 à la figure 1 que ne le permettrait un mouvement de balayage suivant un segment de cercle. The articulated quadrilateral consists of two oscillating arms 24 and 26, one end of which is mounted pendulumly on bearings 28, 30, which are integral with the frame or the bodywork. The other end of the swinging arms 24, 26 is connected in an articulated manner by bearings 32 and 34 to the wiping arm. Thanks to the articulated quadrilateral 28-34, the brush performs a wiping movement on the window 10 which differs from a shape of a circle segment since the pendulum movement is combined with a translational movement generated by the articulated quadrilateral. This allows the wiping field 16 of the brush 22 to better clean a corner bearing the reference 36 in Figure 1 than would allow a sweeping movement along a circle segment.
Comme le montre la figure 2, le palier 34, situé entre l'une des extrémités du levier oscillant 26 et du bras 20, est conçu comme suit. A son extrémité opposée au palier fixe 30, le levier oscillant 26 est muni d'un goujon 38 solidaire du levier oscillant et dont l'extrémité opposée à celle du levier oscillant 26 comporte un chapeau 40 en forme de bride. Entre le chapeau 40 et le levier oscillant 26 se trouve le bras de balayage 20 qui est muni d'un passage 42 à ce niveau. Un élément amortisseur 44 en matière élastique est fixé dans le passage 42. Cet élément amortisseur a essentiellement une forme annulaire et son centre comporte un élément de palier pour le tourillon de palier 38. Dans l'exemple de réalisation, l'élément de pa lier est formé par une douille 46 montée fixe et imperdable dans l'élément amortisseur 44. Celui-ci est lui-même relié solidairement et de manière imperdable au bras de balayage 20. Dans l'exemple de réalisation, cela est assuré par une forme particulière du passage 42 portant la référence 48 à la figure 2-. As shown in Figure 2, the bearing 34, located between one end of the swing lever 26 and the arm 20, is designed as follows. At its end opposite to the fixed bearing 30, the oscillating lever 26 is provided with a stud 38 secured to the oscillating lever and the end opposite to that of the oscillating lever 26 comprises a cap 40 in the form of a flange. Between the cap 40 and the oscillating lever 26 is the scanning arm 20 which is provided with a passage 42 at this level. A damping element 44 of elastic material is fixed in the passage 42. This damping element has essentially an annular shape and its center comprises a bearing element for the bearing pin 38. In the embodiment, the pa is formed by a socket 46 mounted fixed and captive in the damping element 44. The latter is itself integrally and captively connected to the scanning arm 20. In the embodiment, this is ensured by a particular form of the passage 42 bearing the reference 48 in FIG. 2-.
A ses deux extrémités, la douille 46 comporte chaque fois un collet annulaire 50 dépassant des faces frontales respectives de l'élément amortisseur 44. Entre le levier oscillant 26 et le collet annulaire 50 de la douille 46 tourné vers ce levier on a une rondelle 52. La douille de palier 46 est réalisée de préférence en métal. Le montage de l'élément amortisseur élastique 44 est représenté pour le palier 34. On peut toutefois envisager de réaliser également de manière correspondante les points de palier 28, 30, 32, comme cela a été décrit pour le palier 34. At its two ends, the sleeve 46 each has an annular collar 50 projecting from the respective front faces of the damping element 44. Between the oscillating lever 26 and the annular collar 50 of the sleeve 46 turned towards this lever, there is a washer 52 The bearing bush 46 is preferably made of metal. The mounting of the elastic damping element 44 is shown for the bearing 34. However, it is also possible to envisage making the bearing points 28, 30, 32 correspondingly, as has been described for the bearing 34.
L'élément amortisseur 44 élastique permet dans certaines limites un échappement essentiellement radial de l'élément de palier du bras d'essuyage 20, constitué dans l'exemple de réalisation par la douille 46. L'échappement radial signifie également que la douille 46 peut se placer en biais par rapport au bras 20, l'axe de la douille faisant avec l'axe du passage 42 un angle aigu.The elastic damping element 44 allows, within certain limits, an essentially radial escape from the bearing element of the wiping arm 20, constituted in the embodiment by the bush 46. The radial escapement also means that the bush 46 can place itself at an angle to the arm 20, the axis of the sleeve making an acute angle with the axis of the passage 42.
De manière complémentaire, il est à remarquer que l'élément de palier ne signifie pas nécessairement une douille de palier 46 ou un moyen analogue. Il est clair que l'élément de palier peut également être constitué par un perçage de palier réalisé dans l'élément amortisseur 44 et qui guide directement le tourillon de palier 38. In addition, it should be noted that the bearing element does not necessarily mean a bearing bush 46 or the like. It is clear that the bearing element can also be constituted by a bearing hole made in the damping element 44 and which directly guides the bearing pin 38.
