Description

L'invention porte sur le domaine des moteurs à combustion. Elle porte plus précisément sur les moteurs à combustion comportant une pompe haute pression pour l'alimentation et la mise en pression d'un système d'injection de carburant.The invention relates to the field of combustion engines. It relates more specifically to combustion engines comprising a high pressure pump for supplying and pressurizing a fuel injection system.

Les moteurs à combustion, et notamment les moteurs dit à injection directe, c'est-à-dire comportant des injecteurs de carburant débouchant directement dans les chambres de combustion, comportent une pompe à carburant dite « pompe haute pression » permettant de mettre et maintenir en pression le carburant dans une rampe d'alimentation des injecteurs. Bien que plus fréquente sur les moteur de type Diesel, cette technologie peut également concerner les moteurs à allumage commandé (généralement appelés moteurs à essence).The combustion engines, and in particular the direct injection engines, that is to say having fuel injectors opening directly into the combustion chambers, comprise a fuel pump called "high pressure pump" to put and maintain pressurizing the fuel in a feed ramp of the injectors. Although it is more common on Diesel engines, this technology can also include spark ignition engines (commonly known as gasoline engines).

La pompe à haute pression est entrainée mécaniquement par le moteur qu'elle alimente. En pratique, la pompe à haute pression présente un arbre d'entrée, dont la rotation actionne un moyen de pompage, typiquement un piston mobile dans un cylindre.The high-pressure pump is mechanically driven by the engine it feeds. In practice, the high pressure pump has an input shaft, the rotation of which actuates a pumping means, typically a piston movable in a cylinder.

L'arbre de la pompe est doté d'une roue dentée pour son entraînement. La mise en rotation de la roue dentée, et donc de l'arbre d'entrée de la pompe peut être assuré par une autre roue dentée, ou, plus communément par une courroie ou une chaîne. Cette courroie ou chaîne est typiquement celle de distribution du moteur, reliant un vilebrequin du moteur à l'arbre à cames (ou aux arbres à cames) actionnant les soupapes.The pump shaft is equipped with a gear wheel for its drive. The rotation of the toothed wheel, and therefore of the input shaft of the pump can be ensured by another gear, or more commonly by a belt or a chain. This belt or chain is typically that of engine timing, connecting a crankshaft of the engine to the camshaft (or camshafts) actuating the valves.

Un mauvais calage de la pompe haute pression par rapport au vilebrequin induit dans l'ensemble du système des efforts fluctuants dans la courroie se traduisant par des couples induits au niveau des poulies, ce qui est néfaste à la fiabilité dans le temps du système. Généralement, aucun dispositif particulier assurant un calage ou une indexation précise de la pompe haute pression par rapport au vilebrequin du moteur n'est nécessaire, car la pompe est bien souvent entrainée directement par le vilebrequin, de sorte qu'il n'y a pas de structure de transmission (courroie, chaîne, etc.) dans laquelle elle génère des fluctuations. Mais, lorsque la pompe est entrainée via une telle structure de transmission, les fluctuations générées peuvent entraîner une rupture de courroie de distribution, potentiellement destructrice du moteur, ou l'endommagement des paliers ou roulement d'arbres (arbre de pompe, vilebrequin, arbre à came) engendrant un risque de défaillance ou la génération de bruits et vibrations.An incorrect setting of the high pressure pump relative to the crankshaft induces throughout the system of fluctuating stresses in the belt resulting in induced torque at the pulleys, which is detrimental to the reliability over time of the system. Generally, no particular device ensuring accurate setting or indexing of the high pressure pump relative to the crankshaft of the engine is necessary, because the pump is often driven directly by the crankshaft, so that there is no transmission structure (belt, chain, etc.) in which it generates fluctuations. But, when the pump is driven via such a transmission structure, the fluctuations generated can cause a rupture of the timing belt, potentially destructive of the engine, or the damage of the bearings or rolling of shafts (pump shaft, crankshaft, shaft to cam) generating a risk of failure or the generation of noise and vibrations.

En outre, un bon calage entre la pompe haute pression et le moteur est nécessaire pour que les efforts générés par la pompe ne perturbent pas le moteur lors de son démarrage, et, en particulier, il est nécessaire d'avoir un calage optimal pour permettre le démarrage systématique du moteur dans un temps réduit, typiquement en deux points mort hauts du cycle du moteur pour un moteur à 4 cylindres. Cela est fondamental pour les applications automobiles dotées d'un système d'arrêt et redémarrage automatique du moteur (système bien connu sous l'expression anglophone « stop and start »).In addition, a good wedging between the high pressure pump and the motor is necessary so that the forces generated by the pump do not disturb the engine when it starts, and in particular, it is necessary to have an optimal setting to allow the systematic starting of the engine in a reduced time, typically in two high dead points of the engine cycle for a 4-cylinder engine. This is fundamental for automotive applications with an automatic engine shutdown and restart system (known as "stop and start").

On connait du document EP2088308A1 un dispositif correspondant au préambule de la revendication 1.We know of the document EP2088308A1 a device corresponding to the preamble of claim 1.

Il convient donc de concevoir un moyen permettant d'assurer que la pompe est montée, typiquement en usine de montage des moteurs, avec un calage adéquat vis-à-vis du moteur qu'elle équipe. L'invention tend à résoudre cette problématique par un moyen simple.It is therefore necessary to design a means to ensure that the pump is mounted, typically in engine assembly plant, with a suitable timing vis-à-vis the engine that team. The invention aims to solve this problem by a simple means.

Plus précisément, l'invention porte donc sur un dispositif comportant

  • une pompe à carburant pour moteur à combustion, comportant une roue dentée pour son entraînement,
  • un moyen d'indexation immobilisant la roue dentée dans une position donnée par rapport à un corps de la pompe, le moyen d'indexation (2) comportant un moyen de fixation sur le corps de la pompe,
caractérisé en ce que le moyen de fixation comporte une ou plusieurs extensions (24,24') insérées dans des orifices que comporte le corps de la pompeMore precisely, the invention therefore relates to a device comprising
  • a fuel pump for a combustion engine, comprising a gear wheel for its drive,
  • an indexing means immobilizing the toothed wheel in a given position with respect to a body of the pump, the indexing means (2) comprising a fixing means on the body of the pump,
characterized in that the fastening means comprises one or more extensions (24,24 ') inserted into holes in the body of the pump.

L'invention permet ainsi le transport et la manutention d'une pompe à carburant dans une position donnée de son cycle de fonctionnement, ce qui permet de la monter sur un moteur présentant lui-même une position prédéfinie dans son cycle afin de garantir le calage souhaité entre la pompe à carburant et le moteur.The invention thus allows the transport and the handling of a fuel pump in a given position of its operating cycle, which makes it possible to mount it on a motor having itself a predefined position. in its cycle to ensure the desired timing between the fuel pump and the engine.

De préférence, le moyen d'indexation comporte un bouchon de forme interne comportant au moins une dent s'engrenant avec la roue dentée pour la bloquer en rotation vis-à-vis du moyen d'indexation.Preferably, the indexing means comprises an internally shaped plug having at least one tooth meshing with the toothed wheel to lock it in rotation vis-à-vis the indexing means.

De préférence, la roue dentée comporte une marque destinée à être mise en regard d'un repère que comporte le moyen d'indexation. Cette mise en correspondance assure et garantit un calage donné de la pompe dans son cycle.Preferably, the toothed wheel comprises a mark intended to be placed opposite a reference mark that comprises the indexing means. This mapping ensures and ensures a given timing of the pump in its cycle.

De préférence, ces extensions présentent une élasticité radiale de sorte à être maintenues sur la pompe à carburant sous l'effet de cette élasticité.Preferably, these extensions have a radial elasticity so as to be maintained on the fuel pump under the effect of this elasticity.

Selon un mode de réalisation préférentiel de l'invention, chaque extension est insérée dans un orifice de la pompe à carburant destiné à recevoir une vis de montage de la pompe à carburant sur un moteur.According to a preferred embodiment of the invention, each extension is inserted into an orifice of the fuel pump for receiving a mounting screw of the fuel pump on a motor.

L'invention porte aussi sur un procédé de montage d'une pompe à carburant sur un moteur à combustion, caractérisé par les étapes de :

  • Fourniture d'un dispositif tel que précédemment décrit ;
  • Retrait du moyen d'indexation ;
  • Assemblage de la pompe à carburant sur le moteur et de moyens d'entrainements synchrones de la roue dentée.
The invention also relates to a method of mounting a fuel pump on a combustion engine, characterized by the steps of:
  • Providing a device as previously described;
  • Removing the indexing means;
  • Assembly of the fuel pump on the engine and synchronous drive means of the gear wheel.

Selon le mode de réalisation de l'invention, ces deux dernières étapes du procédé peuvent être interverties (le retrait du moyen d'indexation devant précéder nécessairement l'assemblage de la pompe seulement si les moyens de fixation de la pompe sur le moteur, typiquement les alésages dans lesquels on positionne des vis de fixation, sont masqués par le moyen d'indexation, par exemple par les moyens de fixation du moyen d'indexations sur le corps de la pompe.According to the embodiment of the invention, these last two steps of the method can be interchanged (the removal of the indexing means necessarily preceding the assembly of the pump only if the means of fixing the pump on the engine, typically the bores in which fixing screws are positioned are masked by the indexing means, for example by the fixing means of the indexing means on the body of the pump.

L'invention est décrite plus en détail ci-après et en référence aux figures représentant schématiquement le système dans son mode de réalisation préférentiel.The invention is described in more detail below and with reference to the figures schematically showing the system in its preferred embodiment.

La figure 1 présente selon une vue en trois dimensions un dispositif conforme à une variante préférentielle de l'invention.The figure 1 present in a three-dimensional view a device according to a preferred embodiment of the invention.

La figure 2 présente une vue d'un détail d'un dispositif conforme à une variante préférentielle de l'invention.The figure 2 shows a view of a detail of a device according to a preferred embodiment of the invention.

La figure 3 présente selon une vue en trois dimensions d'un premier point de vue un moyen d'indexation tel que mis en jeu dans une variante préférentielle de l'invention.The figure 3 according to a three-dimensional view of a first point of view, an indexing means as implemented in a preferred variant of the invention.

La figure 4 présente selon un second point de vue un moyen d'indexation tel que mis en jeu dans une variante préférentielle de l'invention.The figure 4 presents according to a second point of view an indexing means as implemented in a preferred variant of the invention.

A la figure 1 on a représenté selon une vue en trois dimensions un dispositif conforme à une variante préférentielle de l'invention. Un tel dispositif comprend une pompe à carburant 1. La pompe à carburant 1 est arrangée pour être entraînée en rotation par une roue dentée 11. Lors du montage de pompe sur un moteur, et de sa liaison avec un vilebrequin du moteur à l'aide d'un dispositif d'entrainement synchrone, la position angulaire, le « calage » de la pompe 1 et donc de sa roue dentée 11 d'entraînement doit être parfaitement maîtrisé pour être calé par rapport au cycle de fonctionnement du moteur (typiquement, on cale la pompe par rapport à un point mort bas du moteur).To the figure 1 there is shown in a three-dimensional view a device according to a preferred embodiment of the invention. Such a device comprises a fuel pump 1. The fuel pump 1 is arranged to be rotated by a gear wheel 11. When mounting pump on a motor, and its connection with a crankshaft of the engine using of a synchronous drive device, the angular position, the "setting" of the pump 1 and therefore of its drive gear 11 must be perfectly controlled to be wedged with respect to the operating cycle of the engine (typically hold the pump in relation to a bottom dead center of the engine).

Dans l'invention, un moyen d'indexation 2 est disposé de sorte à immobiliser la roue dentée (et donc la pompe) dans une position prédéfinie. Pour ce faire, le moyen d'indexation peut comporter une dent 23 s'engrenant avec la roue dentée.In the invention, an indexing means 2 is arranged so as to immobilize the toothed wheel (and therefore the pump) in a predefined position. To do this, the indexing means may comprise a tooth 23 meshing with the toothed wheel.

Pour ce faire, le moyen d'indexation est préférentiellement un bouchon présentant une forme interne complémentaire de la roue dentée 11, c'est-à-dire une forme par rapport à laquelle les dents de la roue dentée 11 sont immobilisées en rotation.To do this, the indexing means is preferably a plug having an internal shape complementary to the toothed wheel 11, that is to say a shape with respect to which the teeth of the toothed wheel 11 are immobilized in rotation.

Tel que présenté en détail à la figure 2, une ouverture 21 peut être ménagée dans le moyen d'indexation afin de pouvoir mettre en correspondance une marque 12 portée par la roue dentée 11 avec un repère 22 que comporte le moyen d'indexation 2.As detailed in the figure 2 an opening 21 may be provided in the indexing means in order to be able to match a mark 12 carried by the toothed wheel 11 with a mark 22 which the indexing means 2 comprises.

Afin de maintenir le moyen d'indexation 2 sur le corps de la pompe à carburant 1, on le dote préférentiellement d'une ou plusieurs extensions 24, 24'. Les extensions 24, 24' présentent préférentiellement une élasticité radiale, et tendent à s'écarter lorsqu'elles sont insérées dans des orifices du corps de pompe. Préférentiellement, les extensions 24, 24' sont conformées pour être introduites dans les alésages prévus pour recevoir des vis de fixation de la pompe à carburant 1 sur un moteur. Les moyens de fixations mis en jeu peuvent donc être, comme présenté en figure 3, des plots fendus longitudinalement pour leur conférer une élasticité radiale.In order to maintain the indexing means 2 on the body of the fuel pump 1, it is preferably provided with one or more extensions 24, 24 '. The extensions 24, 24 'preferably have a radial elasticity, and tend to move away when they are inserted into orifices of the pump body. Preferably, the extensions 24, 24 'are shaped to be introduced into the bores provided to receive fixing screws of the fuel pump 1 on a motor. The fastening means involved can therefore be, as presented in figure 3 , split ends longitudinally to give them a radial elasticity.

La figure 4 présente selon un second point de vue le moyen d'indexation 2 présenté en figure 3. Le moyen d'indexation 2 est ici vu « de dessous », c'est-à-dire montrant la cavité dans laquelle la roue dentée de la pompe à carburant 1 sera insérée.The figure 4 according to a second point of view the indexing means 2 presented in figure 3 . The indexing means 2 is here seen "from below", that is to say showing the cavity in which the toothed wheel of the fuel pump 1 will be inserted.

L'invention propose ainsi un dispositif permettant d'assurer le respect de la position du pignon à partir de la fin de l'assemblage chez le fournisseur jusqu'au début de l'assemblage en usine de montage de moteurs. Ainsi, la roue dentée de la pompe est correctement phasée par rapport à sa structure d'entrainement synchrone liée au vilebrequin du moteur, et ce à la dent près. Au final, ceci assure, par la limitation des couples subis, une bonne tenue mécanique de l'ensemble du système d'entrainement, notamment de la courroie qu'il peut comporter.The invention thus provides a device for ensuring compliance with the position of the pinion from the end of the assembly at the supplier until the beginning of assembly in engine assembly plant. Thus, the gear wheel of the pump is properly phased with respect to its synchronous drive structure connected to the crankshaft of the engine, and this to the tooth near. In the end, this ensures, by limiting the torques suffered, a good mechanical strength of the entire drive system, including the belt it may contain.
