Description
REGULATETJR CENTRIFUGE D'UN DISTRIBUTEUR D'ALLUMAGE. REGULATETJR CENTRIFUGAL OF AN IGNITION DISTRIBUTOR.
La présente invention concerne un régulateur centrifuge d'ur distributeur d'allumage pouvmoteur à combustion interne du type comportant un ressort métallique dont l'extrémité en forme de boucle est accroché à un plateau par l'intermédiaire d'un axe métallique solidaire du plateau. The present invention relates to a centrifugal regulator of an internal combustion engine ignition distributor of the type comprising a metal spring, the loop-shaped end of which is attached to a plate by means of a metal axis integral with the plate.
Dans de tels régulateurs centrifuges un frottement se produit au niveau de la liaison du ressort avec l'axe, ces deux éléments étant métalliques il s'ensuit une usure par abrasion au niveau des surfaces de contact. In such centrifugal regulators, friction occurs at the connection of the spring with the axis, these two elements being metallic, this results in abrasion wear at the contact surfaces.
Il est connu de munir l'axe d'une enveloppe en matière plastique, or cet axe est soit rapporté sur le plateau ce qui nécessite une opération de fixation de cet axe sur le plateau soit découpé, puis cambré à l'extérieur du plateau, ce qui entraîne des chutes de matériau importantes. It is known to provide the axis with a plastic envelope, but this axis is either attached to the plate which requires an operation for fixing this axis on the plate is cut, then arched outside the plate, resulting in significant material drops.
La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un régulateur centrifuge d'un distributeur d'allumage pour moteur à combustion interné du type comportant un ressort métallique dont l'extrémité en forme de boucle est accrochée à un plateau par l'intermédiaire d'un axe métallique solidaire du plateau, caractérisé en ce que l'axe est obtenu de matière avec le plateau par extrusion à froid dudit plateau et qu'il comporte des moyens de maintien d'un revetement résistant à l'abrasion qui comporte une torge annulaire sur sa périphérie. The present invention aims to remedy these drawbacks and for this purpose relates to a centrifugal regulator of an ignition distributor for an internal combustion engine of the type comprising a metal spring whose loop-shaped end is hooked to a plate by means of a metal axis integral with the plate, characterized in that the axis is obtained in one piece with the plate by cold extrusion of said plate and that it comprises means for maintaining a coating resistant to abrasion which comprises an annular torge on its periphery.
La description qui va suivre en regard des figures annexées fera mieux comprendre comment l'invention peut être réalisée. The description which follows with reference to the appended figures will make it easier to understand how the invention can be implemented.
La figure 1 représente en coupe un plateau d'un régulateur centrifuge d'un distributeur au niveau de sa liaison avec un ressort métallique. Figure 1 shows in section a plate of a centrifugal regulator of a distributor at its connection with a metal spring.
La figure 2 représente une variante de la liaison du ressort métallique avec le plateau. Figure 2 shows a variant of the connection of the metal spring with the plate.
De façon connue, un régulateur centrifuge pour distributeur d'allumage comporte une pluralité de liaisons entre differents éléments métalliques et notamment entre un plateau 1, un axe 2 solidaire du plateau et un ressort 3. In a known manner, a centrifugal regulator for an ignition distributor comprises a plurality of connections between different metallic elements and in particular between a plate 1, an axis 2 secured to the plate and a spring 3.
Le ressort 3 comporte à son extrémité une boucle 4 qui s'accroche autour de l'axe 2. The spring 3 has at its end a loop 4 which hooks around the axis 2.
Conformément à l'invention l'axe 2 est obtenu de matière avec le plateau 1 par une opération d'extrudage à froid d'une partie du plateau 4, la matière de cette partie est alors repoussée sous la forme de l'axe 2 désiré, à l'extérieur de la face choisie du plateau 1 en laissant un évidement 9 sur la face opposée. According to the invention the axis 2 is obtained from material with the plate 1 by a cold extrusion operation of a part of the plate 4, the material of this part is then pushed back in the form of the desired axis 2 , outside the chosen face of the plate 1, leaving a recess 9 on the opposite face.
Cet axe 2 est ensuite recouvert d'un revêtement 6 résistant à l'abrasion notamment en matériau du type polyamide renforcé fibres de verre. This axis 2 is then covered with an abrasion-resistant coating 6, in particular of material of the polyamide type reinforced with glass fibers.
Selon la figure 1 le revêtement 6 est une gaine 6a enfilée autour de l'axe 2 puis maintenue par un sertissage 7 réalisé à l'extrémité libre de l'axe 2. Cette gaine ou entretoise comporte une gorge 10 sur sa face externe dans laquelle est logée l'extrémité en forme de boucle 4 du ressort 3. According to Figure 1 the coating 6 is a sheath 6a threaded around the axis 2 and then held by a crimping 7 made at the free end of the axis 2. This sheath or spacer has a groove 10 on its outer face in which the loop-shaped end 4 of the spring 3 is housed.
Ce revêtement 6 peut être avantageusement réalisé par un surmoulage 6b sur l'axe 2, lequel comporte des moyens connus de maintien de ce surmoulage 6b, telle que, par exemple une collerette 8 réalisée à l'extrémité dudit axe(tel que représenté à la figure 2) ou des crans réalisés à la périphérie de l'axe 2 lors de l'extrudage, ou tout autre moyen connu. This coating 6 can advantageously be produced by an overmolding 6b on the axis 2, which comprises known means for retaining this overmolding 6b, such as, for example a flange 8 produced at the end of said axis (as shown in FIG. Figure 2) or notches made at the periphery of the axis 2 during extrusion, or any other known means.
