Description
PROCEDE DE MONTAGE SOUS CAISSE D'UN DISPOSITIF METHOD FOR ASSEMBLING A DEVICE
DE POMPE PUMP
[001 ] L'invention concerne un procédé de montage sous caisse d'un dispositif de pompe dans un véhicule automobile. L'invention concerne également un dispositif de pompe doseuse de carburant d'une chaudière de chauffage additionnel et un soubassement de véhicule équipé d'un tel dispositif de pompe. [001] The invention relates to a method of mounting under a box of a pump device in a motor vehicle. The invention also relates to a fuel metering pump device of an additional heating boiler and a vehicle underbody equipped with such a pump device.
[002] La montée en gamme des véhicules automobiles impose aux constructeurs automobiles de trouver des solutions industrialisâmes pour équiper en grande série les véhicules avec des équipements dont le taux de monte était précédemment limité. Il en va ainsi pour les chaudières de chauffage additionnel fonctionnant au carburant de type Webasto (marque déposée). [002] The rise in the range of motor vehicles requires car manufacturers to find industrialized solutions for mass-equipped vehicles with equipment whose rate of rise was previously limited. This is the case for additional heating boilers running on the Webasto type of fuel (registered trademark).
[003] Les chaudières de chauffage additionnel étaient par le passé proposées par les constructeurs automobiles pour équiper des véhicules amenés à circuler dans des zones de grands froids. Elles trouvent aujourd'hui, avec la montée en gamme des véhicules, une application massive dans le préchauffage des habitacles de véhicule ou leur chauffage additionnel en complément du chauffage classique. Ces chaudières produisent de la chaleur de manière autonome par combustion de carburant. Elles sont donc bien adaptées pour la fonction de préchauffage télécommandé de l'habitacle en hiver, qui peut ainsi être proposée avec le moteur thermique à l'arrêt. [004] La chaudière est habituellement implantée dans le bloc avant du véhicule et la l'air chaud produit est soufflée dans l'habitacle. Afin d'amener le carburant jusqu'à la chaudière, une canalisation sous caisse est prévue pour raccorder la chaudière au réservoir de carburant du véhicule. Le réservoir de carburant est généralement implanté sous la deuxième rangée d'assise dans un véhicule de tourisme. Une pompe électrique dite pompe doseuse de carburant doit également être montée dans le raccordement entre la chaudière et le réservoir de carburant. Cette pompe est nécessaire pour doser la quantité de carburant à fournir à la chaudière en fonction des besoins en chauffage. [003] The additional heating boilers were previously proposed by the car manufacturers to equip vehicles to circulate in areas of extreme cold. Today, with the move upmarket of vehicles, they find a massive application in the preheating of vehicle interiors or their additional heating in addition to conventional heating. These boilers produce heat independently by burning fuel. They are therefore well suited for the remote control preheating function of the passenger compartment in winter, which can thus be offered with the engine off. [004] The boiler is usually located in the front block of the vehicle and the hot air produced is blown into the passenger compartment. In order to bring the fuel to the boiler, an underbody pipe is provided to connect the boiler to the vehicle fuel tank. The fuel tank is usually located under the second row of seats in a passenger vehicle. An electric pump called fuel metering pump must also be mounted in the connection between the boiler and the fuel tank. This pump is required to meter the amount of fuel to be supplied to the boiler based on heating requirements.
[005] Différentes implantations de la pompe doseuse de carburant sont connues de l'entité inventive. De manière générale, les implantations connues se situent dans la zone du réservoir de carburant, c'est-à-dire, sous le plancher arrière du véhicule.
[006] Une implantation connue est de fixer la pompe doseuse de carburant à une sangle du réservoir de carburant, au moyen d'un collier d'attache. Cette opération faite par un opérateur « mains en l'air » est applicable pour des petites séries ou pour des installations en après-vente. Elle n'est pas satisfaisante pour des premières-montes en grande série sur des chaînes automatisées de fabrication automobile. [005] Different implantations of the fuel metering pump are known to the inventive entity. In general, known implantations are located in the area of the fuel tank, that is to say, under the rear floor of the vehicle. [006] A known implementation is to fix the fuel metering pump to a strap of the fuel tank, by means of a fastening collar. This operation done by an operator "hands in the air" is applicable for small series or for after-sales installations. It is unsatisfactory for mass-produced first-runs on automated production lines.
[007] Une autre implantation connue prévoit dans le réservoir de carburant un logement dédié dans lequel la pompe doseuse est insérée et y est maintenue mécaniquement par clipsage. De manière à minimiser des modifications sur les éléments environnants du véhicule, la pompe est disposée contre la paroi extérieure du réservoir, dans une zone de la paroi présentant une concavité. Cette solution présente cependant l'inconvénient d'impacter le litrage du réservoir de carburant. Par ailleurs, différents modèles de réservoir sont disponibles chez les constructeurs automobiles pour les véhicules actuels basés sur des plateformes modulaires et cette variabilité entraîne une limitation sur le niveau possible de standardisation. Il en découle des coûts multipliés de recherche et développement et d'outillage, et des réductions de coûts plus faibles. Another known implementation provides in the fuel tank a dedicated housing in which the metering pump is inserted and is held mechanically by clipping. In order to minimize modifications on the surrounding elements of the vehicle, the pump is disposed against the outer wall of the reservoir, in a concavity-zone of the wall. This solution, however, has the disadvantage of impacting the liter of the fuel tank. In addition, different tank models are available from car manufacturers for current vehicles based on modular platforms and this variability leads to a limitation on the possible level of standardization. This results in increased R & D and tooling costs and lower cost reductions.
[008] Par le document EP1238844B1 , il est connu aussi un aménagement pour la fixation dans un véhicule automobile d'une canalisation de carburant située sous caisse. La solution de fixation proposée par EP1238844B1 vise à réduire les vibrations mécaniques de la canalisation de carburant et les bruits acoustiques. Une pompe de carburant et un filtre faisant partie de la canalisation de carburant sont logés dans cet aménagement qui assure leur fixation sous caisse. L'aménagement comporte un élément d'amortissement élastique entourant la canalisation de carburant et maintenu en place entre la tôle du plancher du véhicule et un élément de structure de l'aménagement. Un tel aménagement est plus adapté pour une pompe d'alimentation en carburant du moteur thermique que pour une pompe doseuse de carburant de chaudière de chauffage additionnel. En effet, la pompe doseuse de carburant doit fournir un débit bien plus faible comparativement à celui de la pompe d'alimentation du moteur thermique et le niveau des vibrations produites ne demande pas l'utilisation de moyens d'amortissement élastiques spécifiques. Cet aménagement présente l'inconvénient d'un encombrement important du fait notamment de la présence de l'élément d'amortissement élastique entourant la pompe et le filtre. Cet encombrement important ne facilite pas l'implantation sous caisse et la tenue d'une cote de garde au sol qui doit être respectée entre les organes sous caisse et le plan de la chaussée.
[009] La présente invention vise à apporter une solution aux inconvénients susmentionnés de la technique antérieure en fournissant un montage de pompe de carburant sous caisse bien adapté pour une production industrielle automatisée, offrant un haut niveau de standardisation et qui impacte le moins possible les organes environnants du véhicule. [008] By the document EP1238844B1, it is also known an arrangement for fixing in a motor vehicle of a fuel line located under the body. The fixing solution proposed by EP1238844B1 aims at reducing the mechanical vibrations of the fuel line and the acoustic noises. A fuel pump and a filter forming part of the fuel pipe are housed in this arrangement which ensures their attachment to the body. The arrangement includes an elastic damping element surrounding the fuel line and held in place between the vehicle floor plate and a structural member of the arrangement. Such an arrangement is more suitable for a fuel supply pump of the engine than for an additional heating boiler fuel metering pump. Indeed, the fuel metering pump must provide a much lower flow rate compared to that of the engine fuel pump and the level of vibration produced does not require the use of specific elastic damping means. This arrangement has the disadvantage of a large space due in particular to the presence of the elastic damping element surrounding the pump and the filter. This large size does not facilitate the implementation under the box and the holding of a ground clearance rating that must be respected between the bodies under the body and the floor plan. [009] The present invention aims to provide a solution to the aforementioned drawbacks of the prior art by providing an underbody fuel pump assembly well suited for automated industrial production, offering a high level of standardization and which impacts the organs as little as possible. surrounding the vehicle.
[0010] Selon un premier aspect, l'invention concerne un procédé de montage sous caisse d'un dispositif de pompe dans un véhicule automobile. Conformément à l'invention, le dispositif de pompe est monté sous un plancher avant d'un soubassement du véhicule automobile. [001 1 ] Le plancher avant dans les architectures modulaires actuelles correspond à une zone modulaire présentant une faible variabilité entre les différents véhicules d'une gamme proposée par un constructeur automobile. Le procédé de l'invention autorise donc un haut niveau de standardisation. According to a first aspect, the invention relates to a method of mounting under a box of a pump device in a motor vehicle. According to the invention, the pump device is mounted under a floor before a base of the motor vehicle. [001 1] The front floor in the current modular architectures is a modular area with low variability between the various vehicles of a range proposed by a car manufacturer. The method of the invention therefore allows a high level of standardization.
[0012] Selon une caractéristique particulière, le procédé comprend une étape de mise en place sous caisse du dispositif de pompe à un emplacement prédéterminé sous le plancher avant et une étape de fixation mécanique du dispositif sous le plancher avant, l'emplacement prédéterminé étant situé dans une partie centrale du plancher avant distante de longerons latéraux du soubassement. According to a particular characteristic, the method comprises a step of setting up under the pump device at a predetermined location under the front floor and a mechanical fixing step of the device under the front floor, the predetermined location being located in a central part of the remote front floor of side rails of the underbody.
[0013] Cette caractéristique de l'invention présente l'avantage de mettre à l'abri le dispositif de pompe en cas de choc latéral, évitant ainsi un risque d'incendie par fuite de carburant consécutivement au choc latéral. This feature of the invention has the advantage of sheltering the pump device in the event of a side impact, thus avoiding a risk of fire by fuel leakage following the side impact.
[0014] Selon une autre caractéristique particulière, l'une au moins des étapes susmentionnées de mise en place et de fixation mécanique du dispositif de pompe est réalisée au moins partiellement dans un mode automatique. [0015] Selon un mode particulier de réalisation du procédé de l'invention, l'étape de mise en place comporte une sous-étape de préparation de montage dans laquelle le dispositif de pompe est installé dans un châssis-outillage de montage automatique et une sous- étape de mise en correspondance spatiale sous caisse de ce châssis-outillage avec le soubassement du véhicule. [0016] Selon un autre aspect, l'invention concerne aussi un dispositif de pompe doseuse de carburant de chaudière de chauffage additionnel, apte à être monté sous un plancher
avant de véhicule automobile par la mise en œuvre du procédé de l'invention décrit brièvement ci-dessus. Conformément à l'invention, le dispositif comprend une pompe doseuse de carburant et un boîtier de logement et protection dans lequel est logée la pompe, le boîtier de logement et protection comportant des moyens de fixation mécanique du dispositif sous le plancher avant du véhicule. According to another particular feature, at least one of the aforementioned steps of setting up and mechanical fixing of the pump device is performed at least partially in an automatic mode. According to a particular embodiment of the method of the invention, the implementation step comprises a substep of assembly preparation in which the pump device is installed in an automatic mounting frame-tooling and a sub-step of spatial matching under the box of this chassis-tooling with the underbody of the vehicle. In another aspect, the invention also relates to an additional heating boiler fuel metering pump device, able to be mounted under a floor before a motor vehicle by the implementation of the method of the invention briefly described above. According to the invention, the device comprises a fuel metering pump and a housing housing and protection in which is housed the pump, the housing housing and protection comprising mechanical fixing means of the device under the front floor of the vehicle.
[0017] Selon encore un autre aspect, l'invention concerne un soubassement à architecture modulaire de véhicule automobile, comprenant un plancher avant et équipé de différents organes situés sous caisse. Conformément à l'invention, le dispositif de pompe doseuse de carburant, brièvement décrit ci-dessus, équipe le soubassement et est monté sous le plancher avant dans une partie centrale de celui-ci. According to yet another aspect, the invention relates to a modular motor vehicle base, comprising a front floor and equipped with different bodies located under the body. According to the invention, the fuel metering pump device, briefly described above, equips the underbody and is mounted under the front floor in a central part thereof.
[0018] Selon une caractéristique particulière, le dispositif de pompe doseuse de carburant est monté dans le soubassement sous le plancher avant, entre un renfort de brancard et un renfort de tunnel situés dans ladite partie centrale. According to a particular feature, the fuel metering pump device is mounted in the underbody under the front floor, between a stretcher reinforcement and a tunnel reinforcement located in said central portion.
[0019] Cette implantation du dispositif de pompe doseuse entre deux renforts sous caisse présente l'avantage d'une protection accrue du dispositif. This implantation of the metering pump device between two underbody reinforcements has the advantage of increased protection of the device.
[0020] Selon une autre caractéristique particulière, le plancher avant comprend dans sa face sous caisse une partie concave dans laquelle est monté le dispositif de pompe doseuse de carburant. According to another particular feature, the front floor comprises in its underbody side a concave portion in which is mounted the fuel metering pump device.
[0021 ] La caractéristique ci-dessus pourra être implémentée pour faciliter la tenue d'une cote de garde au sol que doivent respecter les organes montés sous caisse par rapport au plan de la chaussée. The above feature may be implemented to facilitate the holding of a ground clearance rating that must comply with the bodies mounted under body relative to the plane of the roadway.
[0022] Selon encore une autre caractéristique, le dispositif de pompe doseuse de carburant est raccordé à une canalisation de carburant entre un réservoir de carburant du véhicule et une chaudière de chauffage additionnel. [0023] L'invention concerne aussi un véhicule automobile comprenant le soubassement brièvement décrit ci-dessus. According to yet another characteristic, the fuel metering pump device is connected to a fuel line between a fuel tank of the vehicle and an additional heating boiler. The invention also relates to a motor vehicle comprising the underbody briefly described above.

De manière connue, le tunnel 1 13 ayant une forme en U renversé est aligné sur un axe longitudinal central du véhicule et est recouvert d'un revêtement 1 13a. La ligne d'échappement 1 13b est logée dans le tunnel 1 13. Referring to Figs.1 and 2, in a modern vehicle with modular architecture, the equipped base or platform 1 of the vehicle comprises a front block area 10, shown partially, in which is mounted the engine (not shown) , a front floor area 1 1 and a rear floor area 12. Typically, in the front floor areas 1 1 and rear 12 of the vehicle are located in the passenger compartment of the front seat rows and rear (not shown). Front seat rails 1 1 a serving as a support for mounting the front seats of the vehicle are visible in the section of Fig.2. The front floor zone 1 1 comprises first and second side members or rocker 1 10 and 1 10 ', a front floor 1 1 1, the first and second longitudinal stretcher reinforcements 1 12 and 1 12', a floor tunnel 1 13 and first and second longitudinal tunnel reinforcements 1 14 and 1 14 '. In known manner, the tunnel 1 13 having an inverted U shape is aligned on a central longitudinal axis of the vehicle and is covered with a coating 1 13a. The exhaust line 1 13b is housed in the tunnel 1 13.
[0032] Comme montré aux Figs.1 et 2, conformément au procédé de montage selon l'invention, le dispositif de pompe 13 est monté à un emplacement 13a qui est situé sous le plancher avant 1 1 1 .
[0033] Selon un mode de réalisation particulier, l'emplacement 13a se situe dans une zone centrale 14 du plancher avant 1 1 comprise sensiblement entre les renforts de brancard 1 12 et 1 12' du soubassement 1 . Plus précisément, l'emplacement 13a se situe ici entre le renfort de brancard 1 12 et le renfort de tunnel 1 14. Ce choix d'implantation du dispositif de pompe 13 entre les renforts de brancard et de tunnel est avantageux car le dispositif de pompe 13 peut ainsi être placé dans le passage de canalisations 1 15, 1 15a, 1 15b entre l'avant et l'arrière du véhicule, et en particulier dans le passage d'une canalisation de carburant 1 15a qui alimente la chaudière de chauffage additionnel logé dans le bloc avant à partir du réservoir de carburant 1 16 du véhicule situé à l'arrière de celui-ci. L'éloignement par rapport au longeron latéral 1 10 et l'implantation entre les renforts de brancard et de tunnel protègent le dispositif de pompe 13 et les canalisations contre les chocs latéraux. As shown in Figs.1 and 2, according to the mounting method according to the invention, the pump device 13 is mounted at a location 13a which is located under the front floor 1 1 1. According to a particular embodiment, the location 13a is located in a central zone 14 of the front floor 1 1 substantially between the stretcher reinforcements 1 12 and 1 12 'of the base 1. More specifically, the location 13a is here between the stretcher reinforcement 1 12 and the tunnel reinforcement 1 14. This choice of implantation of the pump device 13 between the stretcher and tunnel reinforcements is advantageous because the pump device 13 can thus be placed in the passage of pipes 1 15, 1 15a, 1 15b between the front and the rear of the vehicle, and in particular in the passage of a fuel line 1 15a which feeds the additional heating boiler housed in the front block from the fuel tank 1 16 of the vehicle located at the rear of it. The distance from the side sill 1 10 and the implementation between the stretcher and tunnel reinforcements protect the pump device 13 and the pipes against side impacts.
[0034] En référence plus particulièrement à la section de la Fig.2, on notera que l'emplacement 13a pour le montage du dispositif de pompe 13 ne pose pas de problème pour la tenue de la cote de garde au sol Dmin que doivent respecter l'ensemble des organes montés sous caisse dans un véhicule automobile. La cote de garde au sol Dmin est la distance minimale qui doit être respectée entre le point le plus bas de l'organe concerné et le plan de la chaussée. En effet, dans la grande majorité des applications, le dispositif de pompe 13 se situera au-dessus d'un plan 1 12a d'une face inférieure du renfort de brancard, plan 1 12a qui respecte la cote Dmin. Dans les cas où un encombrement important du dispositif de pompe (pompe de forte puissance) ne permettrait pas le respect de la cote Dmin, l'invention prévoit l'aménagement dans le plancher avant 1 1 1 d'une forme 1 1 1 a en concavité, selon l'axe Z+, qui est montrée en trait pointillé à la Fig.2. Cette forme concave 1 1 1 a est alors aménagée pour y loger le dispositif de pompe 13 et permettre le respect de la cote Dmin. Referring more particularly to the section of Fig.2, it will be noted that the location 13a for mounting the pump device 13 does not pose a problem for the holding of the Dmin ground clearance rating must meet all the bodies mounted under the body in a motor vehicle. The ground clearance rating Dmin is the minimum distance that must be respected between the lowest point of the member concerned and the road surface. Indeed, in the vast majority of applications, the pump device 13 will be above a plane 1 12a of a lower face of the stretcher brace, plane 1 12a which respects the Dmin dimension. In cases where a large size of the pump device (high power pump) would not allow compliance with the Dmin dimension, the invention provides the development in the front floor 1 1 1 of a form 1 1 1 a in concavity, along the Z + axis, which is shown in dashed line in FIG. This concave shape 1 1 1 a is then arranged to accommodate the pump device 13 and allow compliance with the Dmin dimension.
[0035] En référence aux Figs.3 à 5, il est maintenant décrit des étapes d'un mode de réalisation semi-automatisé du procédé de montage sous caisse d'un dispositif de pompe selon l'invention. Referring to Figs.3 to 5, there is now described steps of a semi-automated embodiment of the method of mounting under the box of a pump device according to the invention.
[0036] En référence plus particulièrement à la Fig.3, le procédé comporte une première étape générale S1 qui permettra une mise en place du dispositif de pompe 13 à l'emplacement 13a, avant la fixation mécanique de celui-ci dans une étape S2. L'étape générale S1 comporte deux sous-étapes SS10 et SS1 1 .
[0037] Comme montré à la Fig.4, dans la sous-étape SS10, le dispositif de pompe 13 et d'autres organes à monter sous caisse sont installés dans un châssis-outillage de montage automatique 2 dit châssis POM pour « Préparation des Organes Mécaniques ». Dans ce mode de réalisation particulier du procédé, la sous-étape SS10 est essentiellement réalisée par un opérateur utilisant différents outillages. De manière connue, les positions d'installation du dispositif 13 et d'autres organes dans le châssis- outillage 2 sont définies spatialement dans un repère géométrique (X, Y, Z), en correspondance avec des emplacements de montage sous caisse sur le soubassement 1 . Referring more particularly to FIG. 3, the method comprises a first general step S1 which will allow the pump device 13 to be put in position 13a, before the mechanical fixing thereof in a step S2. . The general step S1 comprises two substeps SS10 and SS1 1. As shown in Fig.4, in the substep SS10, the pump device 13 and other bodies to be mounted underbody are installed in a frame-tooling of automatic assembly 2 said POM chassis for "Preparation of Mechanical Organs ". In this particular embodiment of the method, the sub-step SS10 is essentially performed by an operator using different tools. In a known manner, the installation positions of the device 13 and other members in the tooling frame 2 are defined spatially in a geometric reference (X, Y, Z), in correspondence with underbody mounting locations on the underbody. 1.
[0038] Dans l'étape SS1 1 , le châssis-outillage 2 est soulevé par un élévateur (non représenté) et est verrouillé en position sous le soubassement 1 , le soubassement 1 étant suspendu sur une balancelle qui se déplace de poste en poste dans la chaîne de fabrication. Une mise en correspondance spatiale sous caisse du châssis-outillage 2 avec le soubassement 1 est alors obtenue. Le dispositif de pompe 13 est ainsi en place sous le plancher avant 1 1 1 en regard de l'emplacement 13a. Cette sous-étape SS1 1 est réalisée en mode automatique et termine l'étape générale S1 . In step SS1 1, the chassis-tool 2 is raised by an elevator (not shown) and is locked in position under the base 1, the base 1 being suspended on a swing that moves from station to station in the production line. An under-space spatial mapping of the chassis-tool 2 with the underbody 1 is then obtained. The pump device 13 is thus in place under the front floor 1 1 1 facing the location 13a. This substep SS1 1 is performed in automatic mode and ends the general step S1.
[0039] Dans l'étape S2, le montage du dispositif 13 est achevé par la fixation mécanique de celui-ci sous le plancher avant 1 1 1 , comme montré à la Fig.5. Dans cette étape S2, des outils de poussée, de sertissage et de vissage associés au châssis-outillage 2, tels que des outils de sertissage 20 montrés à la Fig.4, sont actionnés automatiquement pour fixer mécaniquement le dispositif de pompe 13 à son emplacement 13a. In step S2, the mounting of the device 13 is completed by the mechanical attachment thereof under the front floor 1 1 1, as shown in Fig.5. In this step S2, pushing, crimping and screwing tools associated with the tooling frame 2, such as crimping tools 20 shown in FIG. 4, are automatically actuated to mechanically fix the pump device 13 at its location. 13a.
[0040] Le dispositif de pompe 13 représenté aux Figs.4 et 5 est un dispositif de pompe doseuse de carburant pour une chaudière de chauffage additionnel. Le dispositif 13 comprend un boîtier en plastique 130 dans lequel est logé une pompe doseuse de carburant 131 . Une empreinte ayant une forme correspondant à celle de la pompe 131 est prévue dans le boîtier 130 pour recevoir et immobiliser en position la pompe 131 . Dans le boîtier 130, la pompe 131 est raccordée à la conduite de carburant 1 15a et à un câble électrique 1 16 assurant son alimentation électrique. The pump device 13 shown in Figs.4 and 5 is a fuel metering pump device for an additional heating boiler. The device 13 comprises a plastic housing 130 in which is housed a fuel metering pump 131. An impression having a shape corresponding to that of the pump 131 is provided in the housing 130 to receive and immobilize the pump 131 in position. In the housing 130, the pump 131 is connected to the fuel line 1 15a and an electric cable 1 16 providing its power supply.
[0041 ] Comme montré à la Fig.5, une fois le dispositif 13 monté sous caisse, le boîtier 130 recouvre la pompe 131 et protège celle-ci contre des projections et d'éventuels chocs. Le dispositif 13 est fixé sous le plancher avant 1 1 1 par deux écrous 132 et un élément serti en plastique 133a. Les écrous 132 sont vissés sur des goujons soudés sur le plancher avant 1 1 1 dans lesquels sont insérées des pattes de fixation 130a du boîtier. Le
boîtier 130 est aussi fixé à une canalisation 1 15b par l'élément serti 133a, la canalisation 1 15b étant fixée au plancher avant 1 1 1 par d'autres éléments sertis 133b. As shown in Fig.5, once the device 13 mounted underbody, the housing 130 covers the pump 131 and protects it against projections and possible shocks. The device 13 is fixed under the front floor 1 1 1 by two nuts 132 and a crimped plastic element 133a. The nuts 132 are screwed on studs welded to the front floor 1 1 1 in which are inserted fastening tabs 130a of the housing. The The housing 130 is also attached to a pipe 1 15b by the crimped element 133a, the pipe 1 15b being fixed to the floor before 1 1 1 by other crimped elements 133b.
[0042] L'invention ne se limite pas aux modes de réalisation particuliers qui ont été décrits ici à titre d'exemple. Bien que l'invention ait été décrite dans le cadre de son application au montage sous caisse d'une pompe doseuse de carburant de chaudière de chauffage additionnel, il est clair pour l'homme du métier qu'elle trouvera des applications dans le montage sous caisse d'autres types de pompes qui pourraient équiper les véhicules automobiles.
The invention is not limited to the particular embodiments which have been described here by way of example. Although the invention has been described in the context of its application to the box mounting of an additional heating boiler fuel metering pump, it is clear to those skilled in the art that it will find applications in the assembly under crate of other types of pumps that could equip motor vehicles.
