Description
La présente invention revendique la priorité de la demande française
L'invention concerne une fourchette de maintien d'un élément à un support, telle qu'une fourchette de maintien d'un porte-injecteur à une culasse de moteur thermique. L'invention concerne également un dispositif de fixation d'un porte-injecteur à une culasse d'un moteur thermique comprenant une telle fourchette.The invention relates to a fork for holding an element to a support, such as a fork for holding an injector holder to a cylinder head of a heat engine. The invention also relates to a device for fixing an injector holder to a cylinder head of a heat engine comprising such a fork.
Le maintien d'un porte-injecteur sur une culasse de moteur thermique peut être assuré par un élément de maintien du type fourchette ayant une extrémité venant en appui sur une surface supérieure du porte-injecteur, et une autre extrémité venant en appui sur une surface correspondante de la culasse, voir par example le document
Cette fourchette comprend également une ouverture centrale dans laquelle est engagée la vis de serrage qui est vissée dans la culasse. Après positionnement de cette fourchette, l'engagement et le serrage de la vis permettent de bloquer en translation le porte-injecteur en position dans la culasse.This fork also comprises a central opening in which is engaged the clamping screw which is screwed into the cylinder head. After positioning this fork, the engagement and tightening of the screw can block in translation the injector holder in position in the cylinder head.
Cependant, le porte-injecteur a une forme générale cylindrique, et le maintien ou la fixation de celui-ci par une fourchette ne permet pas de le bloquer en rotation avec la précision requise.However, the injector holder has a generally cylindrical shape, and the maintenance or attachment thereof by a fork does not allow to block in rotation with the required accuracy.
Le blocage de l'injecteur dans une position angulaire appropriée autour de son axe de révolution est cependant déterminant en ce qui concerne la qualité de la combustion.The blocking of the injector in an appropriate angular position around its axis of revolution is however decisive as regards the quality of the combustion.
En effet, un tel injecteur comprend une extrémité d'injection située dans la chambre de combustion, d'où partent à chaque injection plusieurs jets distincts qui sont régulièrement espacés les uns des autres autour de l'axe de révolution de l'injecteur.In fact, such an injector comprises an injection end located in the combustion chamber, from which, at each injection, a plurality of separate jets which are regularly spaced from each other around the axis of revolution of the injector.
La qualité de la combustion nécessite entre autres que l'un de ces jets, appelé jet de référence soit très proche de l'extrémité de la bougie d'allumage du moteur.The quality of the combustion requires among other things that one of these jets, called reference jet is very close to the end of the spark plug of the engine.
En cas de mauvais calage de la position angulaire de l'injecteur autour de son axe de révolution, la distance entre l'extrémité de la bougie et le jet le plus proche devient trop importante. Ce défaut de positionnement constitue notamment un handicap lors du démarrage à froid du véhicule et un obstacle à la réduction de la pollution.If the angular position of the injector is misaligned around its axis of revolution, the distance between the end of the candle and the nearest jet becomes too great. This lack of positioning is particularly a handicap during the cold start of the vehicle and an obstacle to the reduction of pollution.
Afin d'améliorer le positionnement angulaire de l'injecteur, il a été envisagé de recourir à une fourchette comprenant deux branches qui viennent en appui sur une surface supérieure du porte-injecteur tout en entourant une tête de ce corps d'injecteur.In order to improve the angular positioning of the injector, it has been envisaged to use a fork comprising two branches which bear against an upper surface of the injector holder while surrounding a head of this injector body.
La tête est prévue avec deux méplats, de sorte que l'engagement de la fourchette sur la tête permet d'immobiliser directement l'injecteur en rotation lors de son montage.The head is provided with two flats, so that the engagement of the fork on the head can directly immobilize the injector in rotation during its assembly.
Cependant, compte tenu de la distance séparant l'extrémité inférieure de l'injecteur et l'extrémité de la bougie, il s'avère qu'un faible écart de la position angulaire de l'injecteur par rapport à une position de référence se traduit par un écart trop important entre la bougie et le jet le plus proche.However, given the distance separating the lower end of the injector and the end of the spark plug, it turns out that a small difference in the angular position of the injector relative to a reference position results. by too great a distance between the candle and the nearest jet.
Le but de l'invention est de proposer une fourchette de maintien ou de fixation d'un porte-injecteur permettant d'assurer un positionnement angulaire précis de cet injecteur lors de son montage.The object of the invention is to provide a holding fork or attachment of an injector holder to ensure accurate angular positioning of the injector during its assembly.
A cet effet, l'invention a pour objet une fourchette de maintien d'un élément à un support, telle qu'une fourchette de maintien d'un porte-injecteur à une culasse de moteur thermique, cette fourchette comprenant une queue destinée à venir en appui sur le support et munie d'une ouverture centrale destinée à recevoir un élément de serrage au support, et deux branches destinées à venir en appui sur l'élément en entourant une tête de cet élément et comprenant au moins un méplat pour bloquer cet élément en rotation. Selon l'invention, la fourchette comporte un élément élastique équipant l'une de ses branches et définissant deux appuis élastiques interposés entre une face interne de cette branche et la tête de l'élément afin de maintenir un méplat de cette tête en appui sur une face interne de la branche opposée.For this purpose, the subject of the invention is a fork for holding an element to a support, such as a fork for holding an injector holder to an engine cylinder head, this fork comprising a tail intended to come supported on the support and provided with a central opening for receiving a clamping element to the support, and two branches intended to bear on the element by surrounding a head of this element and comprising at least one flat to block this rotating element. According to the invention, the fork comprises a resilient element equipping one of its branches and defining two elastic supports interposed between an inner face of this branch and the head of the element in order to maintain a flat part of this head resting on a inner side of the opposite branch.
L'introduction d'un élément élastique entre un bras de fourchette et l'un des deux méplats du porte-Injecteur permet de contrer les efforts résultants du serrage de la vis fixant la fourchette sur le support, contribuant à garder l'alignement de l'axe de symétrie du méplat de Porte-Injecteur par rapport à l'axe de la vis de fixation de la fourchette.The introduction of an elastic element between a fork arm and one of the two flats of the injector holder makes it possible to counter the efforts resulting from the tightening of the screw fixing the fork on the support, helping to keep the alignment of the axis of symmetry of the nozzle carrier flat with respect to the axis of the fork attachment screw.
Dans une variante de réalisation préférée, l'ouverture centrale comprend de plus un siège ayant une forme de révolution assurant un centrage de la fourchette par rapport à une tête de l'élément de serrage lorsque cette vis de serrage est serrée.In a preferred embodiment, the central opening further comprises a seat having a shape of revolution ensuring a centering of the fork relative to a head of the clamping element when the clamping screw is tightened.

Comme représenté dans la
Plus particulièrement, l'ouverture 28 comprend un perçage central débouchant sur une face inférieure de la fourchette et traversé par la tige de la vis 29, ce perçage s'élargissant selon une forme de calotte sphérique 32 sur laquelle vient en appui une surface inférieure complémentaire 33 de la tête de la vis 29.More particularly, the opening 28 comprises a central bore emerging on a lower face of the fork and traversed by the rod of the

Ainsi, l'appui ponctuel 47 supprime un premier degré de liberté en translation verticale de la fourchette, le contact linéique assuré par les touches 48 et 49 supprime deux degrés de liberté en rotation autour de deux axes perpendiculaires entre eux et perpendiculaires à l'axe AX.Thus, the
Les trois autres degrés de liberté restants, comprennent les deux translations possibles de la fourchette dans un plan normal à l'axe AX, et la rotation de la fourchette autour de l'axe AX.The remaining three remaining degrees of freedom include the two possible translations of the range in a plane normal to the axis AX, and the rotation of the range around the axis AX.
Les deux translations possibles sont supprimées par la liaison rotule formée par le siège 34 et la tête 31 de la vis 29. La rotation de la fourchette autour de l'axe AX dans un plan normal à cet axe est quant à elle supprimée par l'engagement des branches 26 et 27 sur la tête 21 du porte-injecteur.The two possible translations are removed by the ball joint formed by the
Il est encore à noter que la fourchette selon l'invention n'induit pas de défaut du positionnement angulaire du porte-injecteur en cas d'écart angulaire entre la vis de serrage 29 et l'axe AX. Ce défaut angulaire est repéré par À en
La fourchette selon l'invention permet ainsi de positionner avec précision le jet de référence 8 par rapport à la tête 6 de la bougie 7, par exemple pour placer la tête 6 et le jet de référence 8 dans un même plan passant par l'axe AX.The fork according to the invention thus makes it possible to accurately position the reference jet 8 with respect to the
Ce positionnement est obtenu simplement en montant la fourchette et en serrant la vis 29, c'est-à-dire sans avoir à effectuer d'ajustement spécifique.This positioning is obtained simply by mounting the fork and tightening the
Le dispositif selon l'invention est tout particulièrement avantageux car il permet un blocage d'un élément à la fois en translation et en rotation avec une grande précision de positionnement.The device according to the invention is particularly advantageous because it allows blocking of an element both in translation and in rotation with a high positioning accuracy.
