FILTRE À AIR DE MOTEUR À COMBUSTION INTERNE [001] L'invention concerne de manière générale le domaine de l'automobile. Plus particulièrement, l'invention se rapporte à un filtre à air pour un moteur à combustion interne de véhicule automobile.AIR FILTER OF AN INTERNAL COMBUSTION ENGINE The invention relates generally to the automotive field. More particularly, the invention relates to an air filter for an internal combustion engine of a motor vehicle.
[002] Les filtres à air comprennent habituellement une cuve sur laquelle vient s'emboîter un couvercle. La cuve est aménagée pour recevoir une cartouche de filtrage d'air. Des conduits d'arrivée d’air et de sortie d’air sont prévus dans le filtre pour la circulation de l’air à travers la cartouche de filtrage. Le couvercle est démontable et autorise l’accessibilité à la cartouche d'air pour son remplacement ou son nettoyage. Le 10 couvercle est rendu solidaire de la cuve au moyen d’éléments de fixation mécanique.Air filters usually include a tank on which a cover fits. The tank is arranged to receive an air filter cartridge. Air inlet and air outlet ducts are provided in the filter for the circulation of air through the filter cartridge. The cover is removable and allows accessibility to the air cartridge for replacement or cleaning. The cover is made integral with the tank by means of mechanical fixing elements.
[003] Différents types d’éléments de fixation mécanique entre le couvercle et la cuve sont utilisés dans les filtres à air de l’état de la technique et permettent la démontabilité du couvercle.Different types of mechanical fastening elements between the cover and the tank are used in air filters of the state of the art and allow the cover to be removed.
[004] Ainsi par EP2256329 il est connu de fixer le couvercle à la cuve du filtre à air par 15 des vis qui sont localisées sur une partie haute du couvercle.[004] Thus by EP2256329 it is known to fix the cover to the tank of the air filter by screws which are located on an upper part of the cover.
[005] Dans FR2691912, il est proposé un filtre à air dont le couvercle est relié au boîtier par des éléments de fixation mécanique de différents types. Dans ce filtre à air, de manière à améliorer l'étanchéité entre le couvercle est la cuve, il est prévu d’utiliser une vis et un étrier localisés en des points de fixation différents du filtre. Les interfaces de 20 fixation mécanique sur le couvercle et la cuve sont différentes entre la vis et l'étrier.In FR2691912, an air filter is proposed, the cover of which is connected to the housing by mechanical fixing elements of different types. In this air filter, in order to improve the seal between the cover and the tank, it is planned to use a screw and a bracket located at different attachment points of the filter. The mechanical fixing interfaces on the cover and the tank are different between the screw and the bracket.
[006] Outre le besoin d’une implantation aisément accessible des éléments de fixation pour les opérations de montage i démontage du couvercle et la nécessité d'obtenir une bonne étanchéité, d’autres contraintes s’appliquent à la fixation du couvercle sur la cuve du filtre à air.In addition to the need for an easily accessible location of the fastening elements for assembly operations and dismantling of the cover and the need to obtain a good seal, other constraints apply to the fixing of the cover to the tank. of the air filter.
[007] En effet, le choix des éléments de fixation mécanique, entre vis, étriers ou clips, est lié aux zones territoriales de commercialisation des véhicules. Des normes différentes peuvent s’appliquer selon les zones de commercialisation et contraignent le choix des éléments de fixation. La périodicité des opérations de remplacement ou de nettoyage des cartouches de filtrage change dans des proportions importantes selon les zones 30 territoriales. Les densités de poussières dans les atmosphères sont très différentes, par exemple, entre les pays développés où les véhicules roulent essentiellement sur des routes bitumées et les pays émergeants où les pistes en terre restent très présentes. Ainsi en Europe, une intervention sur le filtre à air aura fieu tous les 60000 Km environ, alors que dans d’autres zones territoriales celle-ci pourra avoir lieu tous les 3000 Km environ.Indeed, the choice of mechanical fastening elements, between screws, stirrups or clips, is linked to the territorial areas for marketing vehicles. Different standards may apply depending on the marketing areas and constrain the choice of fasteners. The periodicity of the replacement or cleaning operations of the filter cartridges changes in significant proportions depending on the territorial zones. Dust densities in atmospheres are very different, for example, between developed countries where vehicles are driven mainly on paved roads and emerging countries where dirt tracks remain very present. Thus in Europe, an intervention on the air filter will take place every approximately 60,000 km, while in other territorial areas this may take place every approximately 3,000 km.
Lorsque les interventions sont très espacées, il est préférable d'utiliser des vis pour la fixation mécanique du couvercle, celles-ci garantissent une meilleure tenue dans la durée. Par contre, lorsque les interventions sont fréquentes, des éléments de type clip, retirables sans outil, sont plus adaptés. Cette disparité des éléments de fixation est un problème pour les constructeurs automobiles, car ceux-ci sont soucieux d'accroître le niveau de 10 standardisation par des architectures modulaires. Ainsi, pour un même modèle de véhicule, il est actuellement nécessaire d'avoir deux filtres à air qui diffèrent par les interfaces de fixation mécanique aux points de fixation du couvercle sur la cuve. Effet, une interface pour une fixation par vis est différente de celle pour une fixation par clip.When the interventions are widely spaced, it is preferable to use screws for the mechanical fixing of the cover, these guarantee better resistance over time. On the other hand, when interventions are frequent, clip-like elements, removable without tools, are more suitable. This disparity in fasteners is a problem for automobile manufacturers, since they are concerned with increasing the level of standardization by modular architectures. Thus, for the same model of vehicle, it is currently necessary to have two air filters which differ by the mechanical fixing interfaces at the fixing points of the cover on the tank. Indeed, an interface for screw fixing is different from that for clip fixing.
[008] L'invention vise à pallier au problème exposé ci-dessus de la technique 15 antérieure, en fournissant un filtre à air autorisant une standardisation plus importante et des coûts moindres.The invention aims to overcome the above problem of the prior art, by providing an air filter allowing greater standardization and lower costs.

Conformément à l’invention, l'interface de fixation mécanique est apte à recevoir un élément de fixation mécanique sous la forme d’un clip ou d une vis.According to a first aspect, the invention relates to an air filter of an internal combustion engine comprising a tank in which is housed a filter cartridge, a cover and means for mechanically fixing the cover to the tank, the means mechanical fixing comprising at least one mechanical fixing interface formed of first and second mechanical fixing lugs respectively of the cover and the tank and adapted to receive a mechanical fixing element.

'' a mechanical fastener in the form of a clip.
[0012] Selon encore une autre caractéristique particulière, l'une au moins des première et deuxième pattes de fixation mécanique comprend un orifice préformé de passage de vis apte à recevoir un élément de fixation mécanique sous la forme d’une vis.According to yet another particular characteristic, at least one of the first and second mechanical fixing lugs comprises a preformed orifice for the passage of screws capable of receiving a mechanical fixing element in the form of a screw.
[0013] Selon encore une autre caractéristique particulière, le clip formant élément de 5 fixation mécanique comporte deux crans d’accrochage reliés par une partie courbée élastique, les crans d’accrochage ayant une forme générale cylindrique.According to yet another particular characteristic, the clip forming a mechanical fixing element comprises two hooking notches connected by an elastic curved part, the hooking notches having a generally cylindrical shape.

[0018] Une forme de réalisation particulière 1 du filtre à air selon l’invention est 25 maintenant décrite ci-dessous en référence aux Figs. 1 à 4.A particular embodiment 1 of the air filter according to the invention is now described below with reference to Figs. 1 to 4.
[0019] Dans les Figs.1 et 2, le filtre à air 1 est représenté dans sa configuration avec fermeture par clips. La configuration avec fermeture par vis est représentée à la Fig.4.In Figs.1 and 2, the air filter 1 is shown in its configuration with closure by clips. The configuration with screw closure is shown in Fig. 4.
[0020] Comme montré aux Figs.1 et 2, le filtre à air 1 comprend essentiellement une cuve 2, un couvercie 3, une cartouche de filtrage 4 et des clips de fixation mécanique 5.As shown in Figs.1 and 2, the air filter 1 essentially comprises a tank 2, a cover 3, a filter cartridge 4 and mechanical fixing clips 5.
[0021] La cuve 2 est une pièce moulée en plastique de forme globalement parallélépipédique. La cuve 2 comprend des pattes de fixation 20 destinées au montage 5 du filtre à air 1 clans le compartiment moteur du véhicule.The tank 2 is a plastic molded part with a generally parallelepiped shape. The tank 2 comprises fixing lugs 20 intended for mounting 5 of the air filter 1 in the engine compartment of the vehicle.
[0022] La cartouche de filtrage 4 est disposée à l’intérieur de ia cuve 2. Un conduit, non apparent, situé vers le fond de la cuve, amène l'air A à filtrer. L’air A est aspiré à travers la cartouche de filtrage 4, typiquement en papier piissé, et sort par un conduit 30 du couvercle 3.The filter cartridge 4 is disposed inside the tank 2. A pipe, not visible, located towards the bottom of the tank, brings the air A to be filtered. Air A is sucked through the filter cartridge 4, typically of paper paper, and exits through a duct 30 from the cover 3.
[0023] Le couvercle 3 est une pièce moulée en plastique. Le couvercle 3 ferme la cuve 2 par appui d’une lèvre circonférentielle 31 contre une lèvre correspondante 21 de la cuve 2. Les lèvres 31 et 21 sont situées de part et d’autre d’un plan de fermeture PF du filtre 1.The cover 3 is a molded plastic part. The cover 3 closes the tank 2 by pressing a circumferential lip 31 against a corresponding lip 21 of the tank 2. The lips 31 and 21 are located on either side of a closing plane PF of the filter 1.
[0024] Le couvercle 3 est maintenu fixé contre la cuve 2 par trois clips de fixation 5 répartis sur une partie d’un pourtour de la cuve 2 et du couvercie 3. Les clips 5 sont I5 typiquement réalisés par moulage d’un plastique dur élastique. Des clips métalliques pourront aussi être utilisés.The cover 3 is held fixed against the tank 2 by three fixing clips 5 distributed over part of a periphery of the tank 2 and the cover 3. The clips 5 are I5 typically made by molding a hard plastic elastic. Metal clips may also be used.
[0025] Du côté opposé à celui où sont montés les clips 5, des ergots 22, emboîtés mais libres en pivot, sont prévus dans cette forme de réalisation, pour le maintien en position du couvercle 3 et son articulation par rapport à la cuve 2. Bien entendu, dans d’autres formes 20 de réalisation, ces ergots pourront être remplacés par des moyens de fixation par clips ou par vis tels que décrits ici.On the opposite side to that where the clips 5 are mounted, lugs 22, fitted but free in pivot, are provided in this embodiment, for maintaining the position of the cover 3 and its articulation relative to the tank 2 Of course, in other embodiments, these lugs can be replaced by means of fixing by clips or by screws as described here.
[0026] Comme cela apparaît clairement à la Fig.3, montrant le filtre à air 1 avant la mise en place des clips ou des vis, le filtre 1 comporte une interface de fixation mécanique Ml formée de pattes de fixation 32 et 23 au niveau de chaque point de fixation mécanique du 25 couvercle 3 sur la cuve 2.As it clearly appears in Fig.3, showing the air filter 1 before the installation of clips or screws, the filter 1 has a mechanical fixing interface Ml formed by fixing lugs 32 and 23 at the level of each mechanical fixing point of the cover 3 on the tank 2.
[0027] Les pattes 32 et 23 sont en saillie par rapport au plan d’une paroi latérale de cuve 24 située à proximité immédiate. Les pattes 32 et 23 appartiennent respectivement au couvercle 3 et à la cuve 2 et sont jointives par des faces de jonction planes 320, 230, au niveau du plan de fermeture PF entre le couvercle 3 et la cuve 2.The legs 32 and 23 are projecting from the plane of a side wall of the tank 24 located in the immediate vicinity. The lugs 32 and 23 belong respectively to the cover 3 and to the tank 2 and are joined by planar junction faces 320, 230, at the level of the closure plane PF between the cover 3 and the tank 2.
[0028] La patte 32 comprend une face concave 321 qui est opposée à sa face de jonction plane 320. La face concave 321 forme une face femelle d’accrochage apte à coopérer avec ie clip de fixation 5, comme cela apparaît à la Fig.2.The tab 32 comprises a concave face 321 which is opposite to its planar junction face 320. The concave face 321 forms a female hooking face capable of cooperating with the fixing clip 5, as shown in FIG. 2.
[0029] De manière similaire, la patte 23 comprend une face concave 231 qui est opposée à sa face de jonction plane 230. La face concave 231 forme une face femelle d’accrochage apte à coopérer avec le clip de fixation 5, comme cela apparait à la Fig.2.Similarly, the tab 23 comprises a concave face 231 which is opposite to its planar junction face 230. The concave face 231 forms a female hooking face capable of cooperating with the fixing clip 5, as appears in Fig. 2.
