Description

La présente invention concerne un distributeur d'allumage à commande magnétique pour moteur à combustion interne, constitué d'un rotor entraîné en rotation par l'arbre de commande comprenant un manchon susceptible de tourillonner sur l'arbre de commande et sur lequel est fixé un disque à dents polaires coopérant avec le disque correspondant du stator et d'un bobinage disposé entre les éléments polaires du rotor et du stator.The present invention relates to a magnetically controlled ignition distributor for an internal combustion engine, consisting of a rotor driven in rotation by the control shaft comprising a sleeve capable of pivoting on the control shaft and on which is fixed a disc with polar teeth cooperating with the corresponding disc of the stator and of a winding arranged between the polar elements of the rotor and the stator.

Il est connu de tels distributeurs d'allumage à commande magnétique dans lequel le stator est en contact magnétique avec un aimant permanent de forme annulaire concentrique à l'arbre de commande et est constitué d'un disque à dents polaires devant lesquelles défilent les dents polaires du rotor entre lesquels, rotor-stator, est disposé un bobinage porté par un bobineau dont l'embase est maintenue entre les deux paliers supports constituant le boîtier du distributeur.It is known to have such magnetically controlled ignition distributors in which the stator is in magnetic contact with a permanent magnet of annular shape concentric with the control shaft and consists of a disc with polar teeth in front of which the polar teeth pass of the rotor between which, rotor-stator, is disposed a winding carried by a reel whose base is held between the two support bearings constituting the distributor housing.

Dans de tels montages, pour assurer le pincement de l'embase de la bobine et conséquemment son maintien, il importe que les paliers supports soient usinés avec précision.In such arrangements, in order to pinch the base of the coil and consequently maintain it, it is important that the support bearings are machined with precision.

Cette précision est parfois incompatible avec une fabrication de grande diffusion dans laquelle des tolérances d'usinage sont prévues.This precision is sometimes incompatible with mass production in which machining tolerances are provided.

Il se trouve que dans les cas extrêmes de tolérance, le pincement de l'embase ne soit pas assuré de manière effective. Il en résulte du fait des vibrations qui agissent sur le distributeur, une détérioration rapide de celui-ci.It turns out that in extreme cases of tolerance, the pinching of the base is not effectively ensured. As a result of the vibrations which act on the dispenser, this rapidly deteriorates.

L'invention permet de pallier ces inconvénients et concerne à cet effet un distributeur d'allumage à commande magnétique pour moteur à combustion interne du type précité remarquable en ce que l'embase du bobineau sur laquelle est fixée la bobine est enserrée entre les deux paliers supports du boîtier du distributeur par l'intermédiaire d'une bague entretoise élastique.The invention overcomes these drawbacks and for this purpose relates to a magnetically controlled ignition distributor for an internal combustion engine of the aforementioned type remarkable in that the base of the coil on which the coil is fixed is clamped between the two bearings distributor housing supports by means of an elastic spacer ring.

Selon une autre caractéristique de l'invention, la bague entretoise élastique comporte une pluralité de dents équidistantes sur l'un au moins de ses bords périphériques.According to another characteristic of the invention, the elastic spacer ring has a plurality of equidistant teeth on at least one of its peripheral edges.

Le distributeur d'allumage représenté sur la figure 1 est constitué de manière connue de deux paliers supports 1a, 1b dans les coussinets 3, 4 desquels tourillonne l'arbre de commande 2.The ignition distributor represented in FIG. 1 is made up in a known manner of two support bearings 1a, 1b in the bearings 3, 4 of which journals the control shaft 2.

L'arbre de commande 2 porte un rotor 5 constitué d'un manchon 6 qui porte en son extrémité supérieure un disque à dents polaires 7 et entraîné en rotation par l'arbre de commande 2 ; un stator 8 constitué d'un disque à dents polaires 9 contre lequel est disposé un aimant permanent 10 de forme annulaire plat assurant le contact magnétique et disposé concentriquement à l'arbre de commande 2 et maintenu en position par des moyens connus de fixation sur le disque à dents polaires 9, devant lesquelles défilent les dents polaires 7 correspondantes du rotor 5, un bobinage 11 de forme annulaire coaxial à l'arbre de commande 2 et disposé à l'intérieur et entre les éléments polaires du rotor 5 et du stator 8.The control shaft 2 carries a rotor 5 consisting of a sleeve 6 which carries at its upper end a disk with polar teeth 7 and driven in rotation by the control shaft 2; a stator 8 consisting of a polar tooth disc 9 against which is disposed a permanent magnet 10 of flat annular shape ensuring magnetic contact and disposed concentrically with the control shaft 2 and held in position by known means for fixing to the disc with polar teeth 9, in front of which the corresponding polar teeth 7 of the rotor 5 pass, a coil 11 of annular shape coaxial with the control shaft 2 and disposed inside and between the polar elements of the rotor 5 and the stator 8 .

Le bobinage 11 est porté par un bobineau 12 dont l'embase 13 est maintenue en appui conformément à l'invention par une bague entretoise élastique 14 circulaire. La liaison électrique du bobinage 11 est assurée par un dispositif de branchement 15 traversant la cloison du palier support inférieur 1 a du boîtier 1.The coil 11 is carried by a coil 12 whose base 13 is held in abutment in accordance with the invention by an elastic spacer ring 14 circular. The electrical connection of the winding 11 is provided by a connection device 15 passing through the partition of the lower support bearing 1 a of the housing 1.

Selon la représentation de la figure 2, l'embase 13 du bobineau 12 réalisé avantageusement par moulage de matière plastique se présente sous la forme d'une croix dont l'une des branches comporte, fixées par surmoulage sur son extrémité, deux fiches métalliques mâles 19. de connexion adaptées à se raccorder aux extrémités du bobinage 11, lesquelles fiches 19 correspondent à des fiches femelles d'un dispositif de connexion 15 dans lesquelles elles s'insèrent.According to the representation of FIG. 2, the base 13 of the spool 12 advantageously produced by molding of plastic material is in the form of a cross, one of the branches of which comprises, fixed by overmolding on its end, two male metal plugs 19. connection adapted to be connected to the ends of the winding 11, which plugs 19 correspond to female plugs of a connection device 15 into which they are inserted.

L'embase 13 du bobineau 12 repose sur la surface d'appui d'un embrèvement 1c réalisé à l'extrémité libre du palier support 1 a et est indexé en position angulaire par des moyens d'indexation non représentés. On assure de la sorte, l'alignement des fiches entre elles.The base 13 of the coil 12 rests on the bearing surface of a recess 1c produced at the free end of the support bearing 1a and is indexed in angular position by means of indexing not shown. This ensures the alignment of the sheets between them.

Comme représenté sur les figures 2 et 3, la bague entretoise élastique 14 circulaire en matière plastique possède en son bord périphérique supérieur une pluralité de dents 14a obtenues de matières. Chaque dent 14a est constituée d'un groupe de deux lèvres 14b, 14c divergentes. Ces lèvres 14b, 14c sont susceptibles de se déformer par écrasement sous l'action de la force F crée par l'assemblage des deux paliers supports 1 a, 1 b du boîtier 1. Cette déformation élastique permet le rattrapage automatique des jeux.As shown in Figures 2 and 3, the elastic elastic spacer ring 14 made of plastic material has at its upper peripheral edge a plurality of teeth 14a obtained from materials. Each tooth 14a is made up of a group of two divergent lips 14b, 14c. These lips 14b, 14c are liable to deform by crushing under the action of the force F created by the assembly of the two support bearings 1a, 1b of the housing 1. This elastic deformation allows the automatic take-up of the clearances.

A son bord périphérique inférieur, la bague entretoise élastique 14 possède des échancrures 14d dont le fond est en appui sur les branches de l'embase 13 du bobineau 12 et qui déterminent des saillies dont les bords forment des butées empêchant en rotation ladite embase 13 par rapport à la bague entretoise élastique 14.At its lower peripheral edge, the elastic spacer ring 14 has notches 14d, the bottom of which bears on the branches of the base 13 of the bobbin 12 and which determine projections whose edges form stops. preventing said base 13 from rotating relative to the elastic spacer ring 14.

Selon une autre caractéristique de l'invention, l'une de ces dites échancrures 14d se présente sous la forme d'une queue d'aronde 14e adaptée à permettre le passage et le maintien en position du dispositif de connexion 15.According to another characteristic of the invention, one of these said notches 14d is in the form of a dovetail 14e adapted to allow the passage and the holding in position of the connection device 15.

Le dispositif de connexion 15 représenté sur la figure 3 est avantageusement réalisé par moulage de matière plastique et se présente en regard des fiches métalliques mâles 19 de connexion ménagées à l'extrémité de l'une des branches de l'embase 13 du bobineau 12 et sur lesquelles il se raccorde électriquement par l'intermédiaire des fiches femelles correspondantes noyées dans ledit dispositif de connexion 15. Le dispositif de connexion 15 est introduit dans l'ouverture prévue à cet effet dans le palier support inférieur la du boîtier 1 et s'engage dans l'échancrure 14d en forme de queue d'aronde 14e de la bague entretoise élastique 14. Pour cela la partie 15a du dispositif de connexion 15 qui s'encastre dans la queue d'aronde 14e a une forme telle à exercer sur la bague entretoise élastique 14 un effort de bas en haut tendant à procurer une déformation supplémentaire des lèvres (14b, 14c) des dents 14a de cette dernière au droit de l'encastrement.The connection device 15 shown in FIG. 3 is advantageously produced by plastic molding and is presented opposite the male metal plugs 19 for connection formed at the end of one of the branches of the base 13 of the coil 12 and on which it is electrically connected via the corresponding female plugs embedded in said connection device 15. The connection device 15 is inserted into the opening provided for this purpose in the lower support bearing 1a of the housing 1 and engages in the notch 14d in the form of a dovetail 14e of the elastic spacer ring 14. For this, the part 15a of the connection device 15 which is embedded in the dovetail 14e has a shape such as to exert on the ring elastic spacer 14 an effort from bottom to top tending to provide additional deformation of the lips (14b, 14c) of the teeth 14a of the latter at the right of the fitting.

Pour se faire, la partie 15a du dispositif de connexion 15 comporte de moulage, des plans 15b dont les pentes sont approximativement correspondantes à celles de la queue d'aronde 14e de l'échancrure 14d de la bague entretoise élastique 14, mais avec une dépouille progressive pour procurer un effet de coin et de glissement vers le haut.To do this, the part 15a of the connection device 15 comprises molding, planes 15b whose slopes are approximately corresponding to those of the dovetail 14e of the notch 14d of the elastic spacer ring 14, but with a draft progressive to provide a corner effect and upward sliding.

Le mode de réalisation représenté par la figure 4 diffère essentiellement du précédent en ce que la bague entretoise élastique 16 est métallique et comporte sur ses bords périphériques des échancrures 16a ménagées sur l'un de ses bords périphériques correspondant aux saillies 16b de l'autre bord périphérique.The embodiment represented by FIG. 4 essentially differs from the previous one in that the elastic spacer ring 16 is metallic and has on its peripheral edges notches 16a formed on one of its peripheral edges corresponding to the projections 16b on the other edge. peripheral.

Lesdites saillies 16b sont de largeur inférieure aux échancrures 16a et sont disposées approximativement au milieu desdites échancrures 16a.Said projections 16b are of width less than the notches 16a and are arranged approximately in the middle of said notches 16a.

Le palier support 1 du boîtier 1 prend appui, au montage, sur les saillies 16b de la bague entretoise élastique 16 et conséquemment exerce une pression sur l'embase 13 du bobineau 12 par les saillies 16c qui reposent sur les branches de ladite embase 13.The support bearing 1 of the housing 1 is supported, during mounting, on the projections 16b of the elastic spacer ring 16 and consequently exerts pressure on the base 13 of the coil 12 by the projections 16c which rest on the branches of said base 13.

La bague entretoise élastique 16 est obtenue par roulage ou cambrage d'un flanc de manière à ce que le diamètre de ladite bague entretoise élastique 16 soit légèrement plus grand que le diamètre intérieur du palier support inférieur 1a du boîtier 1 ce qui lui donne une certaine élasticité radiale facilitant son maintien provisoire en cours de montage.The elastic spacer ring 16 is obtained by rolling or bending a sidewall so that the diameter of said elastic spacer ring 16 is slightly larger than the inside diameter of the lower support bearing 1a of the housing 1 which gives it a certain radial elasticity facilitating its temporary maintenance during assembly.

Les deux extrémités de la bague entretoise élastique 16 s'insèrent dans une rainure 17b de l'embase 17a du dispositif de connexion 17 et permettent ainsi le verrouillage effectif dudit dispositif de connexion 17.The two ends of the elastic spacer ring 16 are inserted in a groove 17b of the base 17a of the connection device 17 and thus allow the effective locking of said connection device 17.

Selon un autre mode de réalisation représenté de la figure 5, la bague entretoise élastique 18 est métallique et est percée d'une pluralité d'ouverture 18a en forme de lumière, parallèles à ses bords périphériques, lesdites lumières 18a donnant l'élasticité à la bague entretoise élastique 18 en étant disposées approximativement au droit des branches de l'embase 13 du bobineau 12.According to another embodiment shown in Figure 5, the elastic spacer ring 18 is metallic and is pierced with a plurality of apertures 18a in the form of light, parallel to its peripheral edges, said lights 18a giving the elasticity to the elastic spacer ring 18 while being disposed approximately at right angles to the branches of the base 13 of the bobbin 12.

Il est évident que d'autres modes de réalisation de la bague entretoise élastique peuvent être obtenus sans pour cela sortir du cadre de l'invention comme par exemple lesdites bagues peuvent être réalisées indifféremment en matière métallique ou plastique.It is obvious that other embodiments of the elastic spacer ring can be obtained without departing from the scope of the invention, for example said rings can be made either of metallic or plastic material.
