DISPOSITIF DE TRANSMISSION POUR UN ESSUIE-GLACE POUR TRANSMISSION DEVICE FOR A WINDSCREEN WIPER
VEHICULE AUTOMOBILEMOTOR VEHICLE
La présente invention se rapporte à un dispositif de transmission pour un essuie-glace (avant ou arrière) pour The present invention relates to a transmission device for a wiper (front or rear) for
véhicule automobile,.motor vehicle,.
Plus spécifiquement, L'invention a pour objet un dispositif de transmission comprenant un arbre ou goujon porte-bras ayant une extrémité plantée avec interaction More specifically, the subject of the invention is a transmission device comprising a shaft or arm-holding stud having an end planted with interaction
dans une ouverture centrale d'une roue dentée. in a central opening of a toothed wheel.
Selon La technique actuel Le, L'extrémité de cet arbre ou goujon portebras, insérée dans La roue dentée, est dotée d'un créne Lage, et la surface de l'ouverture centra Le de la roue dentée est lisse L'arbre ou goujon porte-bras est réalisé en un matériau (acier) de très bonne qualité, ou dans un matériau présentant des caractéristiques de résistance moyennes, et dans ce second cas, l'extrémité qui doit être plantée dans La roue dentée doit être soumise à un traitement de durcissement, par exemple par induction à haute fréquence. Dans un cas comme dans L'autre, Le dispositif de According to the current technique Le, The end of this shaft or studs, inserted in the toothed wheel, is provided with a lage, and the surface of the central opening Le of the toothed wheel is smooth The tree or stud arm holder is made of a very good quality material (steel), or in a material with average resistance characteristics, and in this second case, the end which must be planted in The toothed wheel must be subjected to a treatment hardening, for example by high frequency induction. In one case as in the other, the device
transmission se révèle plutôt coûteux. transmission is rather expensive.
Le but de la présente invention est de réaliser un dispositif de transmission du type indiqué ci-dessus, qui, à prestations sensiblement équivalentes, serait plus The object of the present invention is to provide a transmission device of the type indicated above, which, with substantially equivalent performance, would be more
simp Le et moins onéreux à réaliser. simp Le and less expensive to make.
Ce but est atteint selon L'invention, au moyen d'un dispositif de transmission du type spécifié ci- dessus, dont La principale caractéristique réside dans le fait que la surface de L'ouverture centra Le de ladite roue dentée est crénelée, et que L'extrémité de L'arbre p Lantée dans Ladite ouverture, avant Le montage, est Lisse. D'une manière qui convient, et qui est par ailleurs déjà connue, ladite roue dentée peut être réalisée par frittage ou découpure Avec ces types d'usinage, le crénelage de l'ouverture centrale de ladite roue dentée est réalisé de façon simple, et n'implique aucun coût This object is achieved according to the invention, by means of a transmission device of the type specified above, the main characteristic of which resides in the fact that the surface of the central opening Le of said toothed wheel is crenellated, and that The end of the lantern shaft in said opening, before mounting, is smooth. In a suitable manner, and which is moreover already known, said toothed wheel can be produced by sintering or cutting. With these types of machining, the aliasing of the central opening of said toothed wheel is carried out in a simple manner, and no cost involved
supplémentaire substantiel.additional substantial.
Selon l'invention, il s'avère donc possible d'utiliser un arbre ou un goujon porte-bras en acier à basse résistance, sans qu'il soit nécessaire d'avoir recours à un traitement local de durcissement par induction, et sans qu'il soit nécessaire de créneler According to the invention, it therefore turns out to be possible to use a shaft or an arm-carrying stud made of low-resistance steel, without the need to have recourse to a local induction hardening treatment, and without '' it is necessary to crenelate
l'extrémité dudit arbre.the end of said tree.
D'autres caractéristiques et avantages de L'invention vont apparaître à La Lecture de la Other characteristics and advantages of the invention will appear on reading the
description détaillée qui suit, effectuée avec référence detailed description which follows, carried out with reference
au dessin annexe, donné à pur titre d'exemple non limitatif, dans lequel est montré en perspective un dispositif de transmission selon l'invention, avant l'opération d'insertion avec interaction de l'arbre ou in the accompanying drawing, given purely by way of nonlimiting example, in which a transmission device according to the invention is shown in perspective, before the insertion operation with interaction of the shaft or
goujon porte-bras, dans la roue dentée d'extrémité. arm support stud, in the end gear.
En se reportant au dessin, un dispositif de transmission pour un essuie-glace pour véhicule automobile selon l'invention comprend un arbre ou goujon porte-bras 1, réalisé par exemple en acier de type 44 Mn 56 Referring to the drawing, a transmission device for a windscreen wiper for a motor vehicle according to the invention comprises a shaft or arm support stud 1, made for example of steel type 44 Mn 56
(résistance environ 880 N/mm 2).(resistance about 880 N / mm 2).
Une extrémité la de l'arbre 1 est lisse, et au cours du montage, e L Le est insérée avec interaction dans l'ouverture centrale 3 a d'une roue dentée 3 Comme cela apparaît sur le dessin, La surface de l'ouverture One end of the shaft 1 is smooth, and during assembly, e L Le is interactively inserted into the central opening 3 a of a toothed wheel 3 As shown in the drawing, The surface of the opening
centrale 3 a de la roue dentée 3 est rayée ou crénelée. central 3 a of the gear 3 is scratched or crenellated.
Cette roue dentée peut être, de façon appropriée, This gear can be, suitably,
réalisée par frittage ou par découpure (potinçonnement). made by sintering or cutting (punching).
Ces types d'usinage permettent de réaliser la roue dentée déjà dotée du crénelage ou rayage interne, sans que ceci ne comporte de difficulté particulière ou n'engendre These types of machining make it possible to produce the toothed wheel already provided with the aliasing or internal scoring, without this presenting any particular difficulty or causing
d'augmentation sensible du coût.significant increase in cost.
L'extrémité la de l'arbre 1 est donc insérée avec interaction dans l'ouverture crénelée 3 a de La roue dentée 3, de manière à rendre lesdits éléments solidaires The end 1a of the shaft 1 is therefore inserted with interaction in the crenellated opening 3a of the toothed wheel 3, so as to make said elements integral
en torsion et axialement.in torsion and axially.
