Description
ARBRE DE DISTRIBUTEUR DALLUMAGE
La présente invention concerne un arbre de distributeur d'allumage notamment pour véhicule automobile, dans lequel l'arbre est retenu axialement dans un palier de tourillonnement.IGNITION DISTRIBUTOR SHAFT
The present invention relates to an ignition distributor shaft, in particular for a motor vehicle, in which the shaft is retained axially in a journal bearing.
Pour assurer une telle retenue il est connu de fixer par soudure électrique une rondelle sur l'arbre, or pour ce faire l'arbre doit comporter à l'opposé de son dispositif d'entrainement un épaulement chanfreiné contre lequel vient s'appuyer la rondelle qui est alors soudée électriquement, de ce fait pour l'obtention d'un tel arbre il est nécessaire d'usiner une partie de l'arbre pour réaliser l'épaulement, de chanfreiner cet épaulement, de souder la rondelle, ce qui entraine une déformation de l'arbre et nécessite une opération de redressage, le prix de revient d'un tel arbre est très élevé.To ensure such retention, it is known to fix a washer on the shaft by electrical welding, but to do this the shaft must have, opposite its drive device, a chamfered shoulder against which the washer bears. which is then electrically welded, therefore to obtain such a shaft it is necessary to machine part of the shaft to make the shoulder, to chamfer this shoulder, to weld the washer, which results in a deformation of the tree and requires a straightening operation, the cost price of such a tree is very high.
La présente invention a pour but de remédier à cet inconvénient et concerne à cet effet un arbre de distributeur d'allumage du type comportant à l'opposé de son dispositif d'entrainement des moyens qui coopérent avec un palier de tourillonnement pour assurer en partie sa retenue axiale dans ledit palier, caractérisé en ce que son diamètre extérieur est le meme de part et d'autre des moyens lesquels sont constitués par une gorge moletée, réalisée dans l'arbre et dons laquelle est immobilisée une rondelle butée obtenue par apport de matière.The object of the present invention is to remedy this drawback and for this purpose relates to an ignition distributor shaft of the type comprising, opposite its drive device, means which cooperate with a journal bearing to partially ensure its axial retainer in said bearing, characterized in that its outer diameter is the same on either side of the means which consist of a knurled groove, produced in the shaft and thus which is immobilized a stop washer obtained by adding material .
La description qui va suivre en regard des schémas annexés fera mieux comprendre comment l'invention peut être réalisée.The description which follows with reference to the appended diagrams will make it easier to understand how the invention can be implemented.
La figure 1 représente en coupe un distributeur équipé d'un arbre conforme à l'invention.Figure 1 shows in section a dispenser equipped with a shaft according to the invention.
La figure 2 représente un arbre connu.Figure 2 shows a known tree.
La figure 3 représente un arbre conforme à l'invention.Figure 3 shows a tree according to the invention.
Le distributeur 5 représenté à . . la figure 1 comprend un boitier qui sert de palier de tourillonnement 2 à l'arbre du distributeur 1 qui entreine en rotation le doigt de distributeur 8 sous la sollicitation du dispositif d'entrainement 4. The distributor 5 shown in. . FIG. 1 comprises a housing which serves as a journaling bearing 2 for the shaft of the distributor 1 which rotates the distributor finger 8 under the stress of the drive device 4.
La retenue axiale de l'arbre 1 dans le palier 2 est réalisée d'une part, vers le dispositif d'entrainement 4, après assemblage de l'arbre dans le palier, par tout élément connu additif tel que "circlips", goupille ; et d'autre part, à l'opposé du dispositif d'entrainement, par des moyens 3 solidaires de l'arbre 1 qui coopérent avec la face correspondante du palier 2. The axial retention of the shaft 1 in the bearing 2 is carried out on the one hand, towards the drive device 4, after assembly of the shaft in the bearing, by any known additive element such as "circlips", pin; and on the other hand, opposite the drive device, by means 3 integral with the shaft 1 which cooperate with the corresponding face of the bearing 2.
L'arbre 10 connu représenté à la figure 2 comporte une partie 13 de diamètre réduit du coté opposé au dispositif d'entrainement, on chanfrein 11 assure la liaison entre la partie 13 et le reste de l'arbore 10, une rondelle en tale 12 est maintenue en appui contre le chanfrein 11, puis soudée électriquenent. Cette soudure nécessite une opération de redressage de 11 arbre 1 qui s'est déformé par l'élévation importante localisée de la température, et peut alors ttre fragile.The known shaft 10 shown in Figure 2 has a portion 13 of reduced diameter on the side opposite to the drive device, chamfer 11 provides the connection between the portion 13 and the rest of the shaft 10, a washer in tale 12 is held in abutment against the chamfer 11, then electrically welded. This welding requires a straightening operation of 11 shaft 1 which has been deformed by the significant localized rise in temperature, and can then be fragile.
Conformément à l'invention l'arbre 1 représenté à la figure 3 n'est soumis à aucune élévation importante de température. According to the invention the shaft 1 shown in Figure 3 is not subject to any significant rise in temperature.
Il est réalisé à partir d'un barreau cylindrique de diamètre constant, dans lequel au niveau des doyens 3 est réalisée une gorge 6 dont le fond est violeté, une rondelle butée 7 est ensuite surmoulée dans cette gorge 6 et est maintenue solidaire de l'arbre 1 par accrochage de la matière dans le moletage. It is produced from a cylindrical bar of constant diameter, in which at the level of the deans 3 a groove 6 is produced, the bottom of which is purple, a stop washer 7 is then molded into this groove 6 and is held integral with the shaft 1 by attachment of the material in the knurling.
Cette rondelle 7 obtenue de préférence par apport d'un alliage de type wzasak" (nom déposé) dans la gorge 6 peut aussi être réalisée en matière plastique suivant les nécessités. L'arbre ainsi obtenu n'a alors subi aucune déformation par de hautes température, sa fragilité est réduite au minimum et il n'y a aucun risque que la soudure cède. This washer 7 preferably obtained by adding an alloy of the wzasak "(registered name) type into the groove 6 can also be made of plastic as required. The shaft thus obtained has not undergone any deformation by high temperature, its fragility is reduced to a minimum and there is no risk that the weld will yield.
