Description

La présente invention concerne un dispositif de fixation amovible pour une bobine d'allumage pour moteur à combustion interne, utilisée notamment dans les dispositifs d'allumage statique du type une bobine par bougie. La présente invention concerne également une bobine d'allumage utilisant ce dispositif.The present invention relates to a removable fixing device for an ignition coil for an internal combustion engine, used in particular in static ignition devices of the coil-by-spark type. The present invention also relates to an ignition coil using this device.

Classiquement un dispositif d'allumage pour moteur à combustion interne est constitué d'un allumeur distributeur comprenant lui-même le rupteur, le condensateur, le système d'avance centrifuge complété par un ou plusieurs dispositifs de corrections à dépression et enfin le doigt de distribution dans la tête d'allumeur, appelée encore tête de distribution, d'une bobine haute tension et de bougies, une par cylindre en général.Conventionally, an ignition device for an internal combustion engine consists of a distributor igniter itself comprising the breaker, the condenser, the centrifugal advance system supplemented by one or more vacuum correction devices and finally the distribution finger. in the igniter head, also called distribution head, a high-voltage coil and spark plugs, one per cylinder in general.

Les limites de cet allumage "mécanique" classique sont nombreuses, on peut citer : la tenue des contacts du rupteur dans le temps, l'optimisation de la bobine difficile : compromis entre énergie élevée et limitation de l'intensité du courant primaire coupé par le rupteur, etc...The limits of this classic "mechanical" ignition are numerous, we can cite: the resistance of the contactor over time, the optimization of the coil difficult: compromise between high energy and limitation of the intensity of the primary current cut by the breaker, etc ...

Les exigences des moteurs modernes, en matière de consommation, de performances et de pollution et le développement de l'électronique ont conduit à la mise au point de nouveaux dispositifs d'allumage et en particulier les dispositifs d'allumage dits "statique" dans lesquels ont été supprimées toute ou partie des pièces mécaniques sujettent à l'usure en les remplaçant par des éléments statiques à base d'électronique. Parmi les différents dispositifs réalisés, le plus avancé technologiquement et le plus performant est l'allumage électronique intégral avec une bobine par bougie. Cette organisation basée sur l'utilisation d'une bobine par bougie permet notamment de supprimer le faisceau de câbles haute tension puisque les bobines sont disposées le plus attenantes possible des bougies qu'elles desservent : chaque bobine se situant au-dessus de sa bougie sensiblement dans l'axe de cette dernière. Différents montages ont vu le jour, on peut notamment cité l'allumage S.D.I. développé par la société SAAB, décrit dans le brevet EP-153.927, à décharge capacitive, entièrement statique, à avance cartographique et commandé par microprocesseur avec positionnement angulaire et régime moteur fournis par un capteur sur le vilebrequin. Cet allumage comporte toute la partie haute tension contenue dans une cassette métallique, cette cassette s'enchassant dans le couvre-culasse.The requirements of modern engines, in terms of consumption, performance and pollution and the development of electronics have led to the development of new ignition devices and in particular so-called "static" ignition devices in which all or part of the mechanical parts subject to wear have been removed by replacing them with static electronic components. Among the various devices produced, the most technologically advanced and the most efficient is the integral electronic ignition with one coil per spark plug. This use-based organization of a coil per spark plug allows in particular to remove the bundle of high voltage cables since the coils are arranged as adjoining as possible to the spark plugs they serve: each coil being located above its spark plug substantially in the axis of the latter . Various assemblies have emerged, in particular the SDI ignition developed by the company SAAB, described in patent EP-153,927, with capacitive discharge, entirely static, with map advance and controlled by microprocessor with angular positioning and engine speed supplied by a sensor on the crankshaft. This ignition includes all the high-voltage part contained in a metal cassette, this cassette being encased in the cylinder head cover.

L'inconvénient d'un tel système est le manque d'accessibilité aux bougies, en effet pour accéder à une bougie il convient de déposer toute la cassette, or le changement des bougies demeurent encore une opération assez fréquente et qui doit demeurer à la portée des particuliers.The disadvantage of such a system is the lack of accessibility to the candles, in fact to access a candle it is necessary to remove the entire cassette, or changing the candles is still a fairly frequent operation and must remain within reach individual.

La présente invention a donc pour objectif un dispositif de fixation amovible d'une bobine pour dispositif d'allumage statique sur un couvre-culasse qui permet rapidement et aisément le montage et le démontage de la bobine de manière à accéder facilement à la bougie et qui soit très peu onéreux.The present invention therefore has for its object a removable fixing device for a coil for a static ignition device on a cylinder head cover which allows quickly and easily the assembly and disassembly of the coil so as to easily access the spark plug and which either very inexpensive.

Conformément à l'invention, le dispositif de fixation amovible sur un couvre-culasse de moteur à combustion interne d'une bobine d'allumage, utilisée notamment pour la mise en oeuvre d'un dispositif d'allumage statique du type une bobine par bougie, est caractérisé en ce qu'il comprend au moins une agrafe élastique,ment déformable qui est fixée par une extrémité sur la bobine d'allumage et dont l'autre extrémité coopère élastiquement avec le couvre-culasse.According to the invention, the removable fixing device on a cylinder head cover of an internal combustion engine of an ignition coil, used in particular for the implementation of a static ignition device of the coil by spark plug type , is characterized in that it comprises at least one elastic, mentally deformable clip which is fixed by one end to the ignition coil and the other end of which cooperates elastically with the cylinder head cover.

Selon une autre caractéristique de l'invention, le dispositif de fixation comprend deux agrafes disposées de part et d'autre de la bobine, ces agrafes obtenues par moulage faisant partie intégrante du boîtier ou carter de la bobine d'allumage.According to another characteristic of the invention, the fixing device comprises two clips arranged on either side of the coil, these clips obtained by molding forming an integral part of the housing or casing of the ignition coil.

Selon une autre caractéristique de l'invention , ladite agrafe présente sensiblement la forme d'un U dont l'une des branches est fixée à la bobine d'allumage et dont l'autre branche comporte un décrochement coopérant élastiquement avec un épaulement porté par le couvre-culasse.According to another characteristic of the invention, said clip has substantially the shape of a U, one of the branches of which is fixed to the ignition coil and the other branch of which has a recess which cooperates elastically with a shoulder carried by the cylinder head cover.

L'invention concerne également une bobine d'allumage pour moteur à combustion interne, utilisée notamment pour la mise en oeuvre d'un dispositif d'allumage statique du type une bobine par bougie, agencée pour un dispositif de fixation selon l'invention.The invention also relates to an ignition coil for an internal combustion engine, used in particular for the implementation of a static ignition device of the coil-by-spark type, arranged for a fixing device according to the invention.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit d'un mode de réalisation de l'invention donnée à titre d'exemple non limitatif en référence au dessin annexé dans lequel :

  • la figure 1 est une vue en élévation d'une bobine d'allumage associée à une bougie montée sur une culasse visible en coupe,
  • la figure 2 est une de dessus du même ensemble.
Other characteristics and advantages of the invention will appear better in the following detailed description of an embodiment of the invention given by way of nonlimiting example with reference to the appended drawing in which:
  • FIG. 1 is an elevation view of an ignition coil associated with a spark plug mounted on a cylinder head visible in section,
  • Figure 2 is a top view of the same assembly.

En se reportant aux figures on voit une bobine d'allumage 3 logée en partie dans un évidement 8 du couvre-culasse 6 du moteur à combustion dont seules les parties constitutives de l'invention ont été figurées.Referring to the figures we see an ignition coil 3 housed in part in a recess 8 of the cylinder head cover 6 of the combustion engine of which only the constituent parts of the invention have been shown.

La bobine 3 est connectée à une bougie 4 par l'intermédiaire d'une douille 2 cylindrique assurant la liaison électrique. La bobine 3 se trouve ainsi disposée à la verticale du puit de bougie 7 formé dans la culasse 1 du moteur.The coil 3 is connected to a spark plug 4 by means of a cylindrical socket 2 ensuring the electrical connection. The coil 3 is thus placed vertically on the spark plug well 7 formed in the cylinder head 1 of the engine.

La bobine 3 se présente extérieurement sous la forme d'un boîtier 10 de forme sensiblement parallélépipèdique comportant un collet périphérique 13 également parallélépipèdique. Ce boîtier 10 en matière plastique obtenu par moulage comporte deux prolongations 5 formant deux agrafes élastiquement déformables en saillie sur deux côtés opposés du boîtier 10.The coil 3 is externally in the form of a housing 10 of substantially parallelepiped shape having a peripheral collar 13 also parallelepiped. This plastic housing 10 obtained by molding has two extensions 5 forming two elastically deformable staples projecting on two opposite sides of the housing 10.

Ces agrafes 15, assurent la fixation amovible de la bobine 3 sur le couvre-culasse 6, conformément à l'invention.These staples 15 ensure the removable fixing of the coil 3 on the cylinder head cover 6, in accordance with the invention.

Les agrafes 5 présentent une forme sensiblement un U. L'une des branches du U, formant chaque agrafe, est rattachée au boîtier 10 au niveau du collet 13 tandis que l'autre branche comporte un décrochement 12 qui est apte à prendre élastiquement appui sous un épaulement 9 du couvre-culasse 6 en saillie dans l'évidement 8 et présente une extrémité libre recourbée vers le boîtier 10.The staples 5 have a shape substantially a U. One of the branches of the U, forming each staple, is attached to the housing 10 at the level of the collar 13 while the other branch has a recess 12 which is able to take elastic support under a shoulder 9 of the cylinder head cover 6 projecting into the recess 8 and has a free end curved towards the housing 10.

La forme de l'évidement 8 est parfaitement complémentaire au boîtier 10 de la bobine 3 ce qui empêche tout déplacement de cette dernière dans le plan horizontal tandis que le fond de l'évidement 8 et les épaulements 9 empêchent tout déplacement vertical.The shape of the recess 8 is perfectly complementary to the housing 10 of the coil 3 which prevents any displacement of the latter in the horizontal plane while the bottom of the recess 8 and the shoulders 9 prevent any vertical displacement.

Le déblocage de la bobine s'effectue très simplement, il suffit de presser les extrémités libres des deux agrafes 5 vers le boîtier 10 pour dégager les décrochements 12 des épaulements 9 puis d'extraire verticalement la bobine. Le blocage est encore plus simple puisqu'il suffit d'enfoncer la bobine dans son logement pour que les agrafes 5 se mettent seules en positions et assurent le verrouillage de la bobine 3 sur le couvre-culasse 6, les décrochements 12 en appui sous les épaulements 9.The release of the coil is very simple, just press the free ends of the two clips 5 towards the housing 10 to release the recesses 12 of the shoulders 9 and then extract the coil vertically. The blocking is even simpler since it suffices to push the reel into its housing so that the clips 5 move into position alone and ensure the locking of the reel 3 on the cylinder head cover 6, the recesses 12 bearing under the shoulders 9.

On a donc réalisé suivant l'invention une fixation amovible pour une bobine d'allumage pour moteur à combustion interne, utilisée notamment dans les dispositifs d'allumage statique du type une bobine par bougie, qui est d'une conception simple, peu coûteuse et qui permet le montage et le démontage sans outillage spécial de cette bobine.There is therefore produced according to the invention a removable attachment for an ignition coil for an internal combustion engine, used in particular in static ignition devices of the coil-by-spark type, which is of a simple design, inexpensive and which allows the assembly and disassembly without special tools of this coil.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Ainsi les deux prolongations 5 formant deux agrafes élastiquement déformables peuvent être fabriquées séparément du boîtier 9 et assemblées à ce boîtier par vissage, collage ou tout autre moyen de fixage.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example. Thus the two extensions 5 forming two elastically deformable staples can be manufactured separately from the housing 9 and assembled to this housing by screwing, gluing or any other fixing means.
