Description

La présente invention concerne un dispositif d'avance centrifuge pour distributeur d'allumage de moteur à combustion interne.The present invention relates to a centrifugal advance device for an ignition distributor of an internal combustion engine.

Les dispositifs d'avance centrifuge connus sont plus particulièrement constitués d'un régulateur centrifuge à masselottes comportant de nombreux éléments qui se déplacent les uns par rapport aux autres intérieurement ou en surface ce qui implique leur frottement entre eux et conséquemment leur usure.The known centrifugal advance devices consist more particularly of a centrifugal flyweight regulator comprising numerous elements which move relative to one another internally or on the surface, which implies their friction with one another and consequently their wear.

Il est connu d'employer le plus souvent possible une matière plastique pour les surfaces de contact ce qui réduit notablement cette usure mais alors chaque type de régulateur d'avance est constitué de pièces spécifiques différentes selon l'amplitude de l'avance désirée et le sens de rotation SH ou SIH de l'arbre de rotation ce qui, devant la pluralité de régulateurs d'avances nécessaire pour équiper un parc de véhicules, entraine une multiplication importante des références des éléments constitutifs et conséquemment un prix de revient inutilement élevé.It is known to use as often as possible a plastic material for the contact surfaces which considerably reduces this wear but then each type of advance regulator is made up of different specific parts according to the amplitude of the desired advance and the direction of rotation SH or SIH of the rotation shaft which, in front of the plurality of advance regulators necessary to equip a fleet of vehicles, leads to a significant multiplication of the references of the constituent elements and consequently an unnecessarily high cost price.

La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un dispositif d'avance centrifuge pour distributeur d'allumage de moteur à combustion interne du type constitué d'un plateau solidaire de l'arbre de commande du distributeur, plateau qui comporte : des pions autour desquels pivotent des masses centrifuges sous l'action de la vitesse de rotation de l'arbre de commande, des butées de limitation du pivotement des masses centrifuges, des pions qui permettent sa liaison souple au moyen de ressorts avec un plateau solidaire d'un des éléments du dispositif de déclenchement de l'allumage et qui comporte des pions qui limitent son décalage angulaire par rapport au plateau en venant en contact contre des butées dudit plateau et qui sont guidés dans des lumières réalisées dans le plateau, dispositif caractérisé en ce que les butées sont rapportées dans des logements réalisés dans le plateau et sont obtenues, lors d'une unique opération de moulage de matériau plastique, solidairement avec une rondelle de frottement fixée sous le plateau entre ce plateau et le boitier du distributeur d'allumage.The present invention aims to remedy these drawbacks and for this purpose relates to a centrifugal advance device for an internal combustion engine ignition distributor of the type consisting of a plate integral with the control shaft of the distributor, plate which includes: pins around which centrifugal masses pivot under the action of the speed of rotation of the control shaft, stops limiting the pivoting of the centrifugal masses, pins which allow its flexible connection by means of springs with a plate secured to one of the elements of the ignition triggering device and which comprises pins which limit its angular offset relative to the plate by coming into contact against the stops of said plate and which are guided in lights made in the plate, device characterized in that the stops are attached in housings made in the plate and are obtained, during a single material molding operation plastic, integrally with a friction washer fixed under the plate between this plate and the case of the ignition distributor.

  • La figure 4 est une vue en plan du plateau solidaire de l'arbre de commande du distributeur d'allumage.Figure 4 is a plan view of the plate secured to the control shaft of the ignition distributor.

De façon connue, selon la figure 1, le dispositif d'avance centrifuge est constitué d'un plateau 5 solidaire de l'arbre de commande1 du distributeur d'allumage : ce plateau 5 comporte : deux pions 6 diamétralement opposés autour desquels pivotent des masses centrifuges 7 sous l'action de la vitesse de rotation de l'arbre de commander deux butées 54 de limitation de pivotement des masses 7 ; deux pions12 diamétralement opposés dont la tête est reliée au moyen d'un ressort13 à la tête de deux pions 9 solidaires d'un plateau 11 solidaire d'un manchon 3 coaxial à l'arbre de commande 1 et porteur d'un élément 4 du dispositif de déclenchement de l'allumage ; deux lumières 52 dans lesquelles sont guidées les extrémités libres des pions 9 jusqu'à venir en contact avec des butées réalisées sur le plateau 5.In known manner, according to FIG. 1, the centrifugal advance device consists of a plate 5 secured to the control shaft 1 of the ignition distributor: this plate 5 comprises: two diametrically opposed pins 6 around which masses pivot centrifugal 7 under the action of the speed of rotation of the shaft to control two stops 54 for limiting the pivoting of the masses 7; two diametrically opposite pins 12, the head of which is connected by means of a spring 13 to the head of two pins 9 secured to a plate 11 secured to a sleeve 3 coaxial with the control shaft 1 and carrying an element 4 of the ignition trigger; two slots 52 in which the free ends of the pins 9 are guided until they come into contact with stops produced on the plate 5.

Dans le distributeur représenté à la figure 1 l'élément 4 du dispositif de déclenchement de l'allumage se présente sous la forme d'une pluralité de cornes qui défilent devant des cornes polaires fixes(non représentées).In the distributor shown in FIG. 1, the element 4 of the ignition triggering device is in the form of a plurality of horns which pass in front of fixed pole horns (not shown).

Cet élément 4 est progressivement décalé angulairement par rappor aux cornes polaires fixes sous l'action des masses 7 qui appuient sur une came 8 solidaire du manchon 3 lors de leur oscillation autour de leur pion 6 suivant la vitesse de rotation de l'arbre de commande 1.This element 4 is gradually angularly offset with respect to the fixed pole horns under the action of the masses 7 which press on a cam 8 secured to the sleeve 3 during their oscillation around their pin 6 according to the speed of rotation of the control shaft 1.

Le plateau 11 assure la limitation des sauts éventuels des masses 7 qui ne sont pas maintenues longitudinalement sur leur pion 6 de pivo tement.The plate 11 ensures the limitation of any jumps of the masses 7 which are not held longitudinally on their pin 6 of pivoting.

Conformément à l'invention les butées 101 qui limitent la course des pions 9 sont réalisées dans une rondelle de frottement 10 qui est ensuite fixée sous le plateau 5 entre ce plateau et le boitier 2 du distributeur d'allumage.According to the invention, the stops 101 which limit the stroke of the pins 9 are produced in a friction washer 10 which is then fixed under the plate 5 between this plate and the box 2 of the ignition distributor.

Cette rondelle de frottement 10 réalisée par moulage d'un matéria plastique se présente sous l'aspect d'un disque qui comporte deux oreilles dans lesquelles sont obtenus des pions 103 de maintien de ladite rondelle sous le plateau 5 et une partie centrale évidée pour le passage de l'arbre de commande 1.This friction washer 10 produced by molding a plastic material has the appearance of a disc which has two ears in which pins 103 are obtained for holding said washer under the plate 5 and a central part hollowed out for the passage of the control shaft 1.

Les butées 101 au nombre de deux sont diamétralement opposées et forment deux ressauts sur la surface de la rondelle et sont jouxtées chacune de part et d'autre par deux lumières 102, les quatre lumières ainsi réalisées sont concentriques à la rondelle et assurent un meilleur guidage des pions 9 par leur extrémité.The stops 101, two in number, are diametrically opposite and form two projections on the surface of the washer and are adjoined each on either side by two slots 102, the four slots thus produced are concentric with the washer and provide better guidance pawns 9 by their ends.

Afin de permetre l'assemblage de la rondelle de frottement 10 sous le plateau 5 celui-ci comporte deux trous 53 dans lesquels pénètrent les pions 103 de la rondelle 10 puis sont écrasés pour assurer un maintien par sertissage ; le plateau 5 comporte deux logements 51 de forme équivalente à celle des butées 101, jouxtées par une lumière 52, les deux lumières 52 ainsi réalisées sont diamétralement opposées.In order to allow the assembly of the friction washer 10 under the plate 5, the latter has two holes 53 into which the pins 103 of the washer 10 penetrate and are then flattened to maintain by crimping; the plate 5 comprises two housings 51 of shape equivalent to that of the stops 101, adjoined by a slot 52, the two slots 52 thus produced are diametrically opposite.

Lors du montage de la rondelle 10 sous le plateau 5 les lumières 52 sont en concordance avec deux lumières 102 diamétralement opposées.When mounting the washer 10 under the plate 5 the lights 52 are in agreement with two diametrically opposite lights 102.

Pour les variations de l'amplitude de l'avance, l'outil de découpe des lumières 52 est simplement décalé angulairement par rapport à un axe de référence donnée correspondant à une avance nulle telle que représenté par la position des pions 9 repère A, en traits interrompus) dans les lumières 102 et 52 visibles sur les figures 3b et 4.For variations in the amplitude of the advance, the light cutting tool 52 is simply angularly offset with respect to a given reference axis corresponding to a zero advance as represented by the position of the pins 9 mark A, in broken lines) in the slots 102 and 52 visible in FIGS. 3b and 4.

Le fait de réaliser les butées indépendantes du plateau 5 permet une standardisation de ce plateau pour les deux sens de rotation possibles de l'arbre de commande 1. Ainsi le plateau 5 peut être découpé de façon standard avec les logements de butée 51 et les lumières qui les jouxtent 52, ainsi que deux pattes diamétralement opposées qui après cambrage rempliront le rôle des butées de masses 54 -Suivant le sens de rotation de l'arbre, la rondelle 10 sera fixée sur la face adéquate du plateau 5 et les pattes 54 cambrées vers l'autre face. La rondelle 10 comportant quatre lumières 102 quelle que soit la face du plateau 5 qui la porte, deux lumières 102 seront toujours en concordance avec les lumières 52 du plateau.The fact of making the independent stops of the plate 5 allows a standardization of this plate for the two possible directions of rotation of the control shaft 1. Thus the plate 5 can be cut in a standard manner with the stop housings 51 and the lights which adjoin them 52, as well as two diametrically opposite lugs which after bending will fulfill the role of the mass stops 54 -Following the direction of rotation of the shaft, the washer 10 will be fixed on the appropriate face of the plate 5 and the lugs 54 cambered towards the other side. The washer 10 having four lights 102 whatever the face of the plate 5 which carries it, two lights 102 will always be in agreement with the lights 52 of the plate.

Un telle réalisation permet d'utiliser une même gamme d'éléments constitutifs du dispositif d'avance centrifuge quelle que soit l'amplitude d'avance désirée et quel que soit le sens de rotation SH et SIH de l'arbre de commande 1.Such an embodiment makes it possible to use the same range of constituent elements of the centrifugal advance device whatever the desired amplitude of advance and whatever the direction of rotation SH and SIH of the control shaft 1.
