Description

La présente invention se rapporte principalement à un dispositif d'interconnexion, notamment hydraulique et pneumatique pour divers organes d'un moteur à combustion interne d'un véhicule automobile.The present invention relates mainly to an interconnection device, in particular hydraulic and pneumatic for various members of an internal combustion engine of a motor vehicle.

Le bon fonctionnement d'un moteur de véhicule automobile ne peut être assuré sans la connexion des divers circuits pneumatiques, hydrauliques et électriques raccordant divers organes du moteur entre eux ainsi qu'à des dispositifs externes. Lors du montage du véhicule ou de sa maintenance, il est donc impératif d'assurer le passage et la connexion de nombreux corps allongés, notamment de conduites tubulaires flexibles, de conduites tubulaires rigides, des câbles ou faisceaux de câbles, dans le compartiment moteur.The proper functioning of a motor vehicle engine cannot be ensured without the connection of the various pneumatic, hydraulic and electrical circuits connecting various parts of the engine to each other as well as to external devices. During vehicle assembly or maintenance, it is therefore imperative to ensure the passage and connection of many elongated bodies, in particular flexible tubular conduits, rigid tubular conduits, cables or cable bundles, in the engine compartment.

Cela ne va pas sans poser de nombreux problèmes aux constructeurs automobiles.This is not without causing many problems for car manufacturers.

Les chemins de divers corps allongés doivent tenir compte non seulement de l'espace disponible dans le compartiment moteur, mais également de la proximité des éléments chauds comme les pièces du moteur ou certaines conduites tubulaires risquant de compromettre le bon fonctionnement des corps allongés fragiles ou contenant des liquides froids. De même, il peut être nécessaire d'éloigner les câbles des sources de perturbation électrique et/ou magnétique. Ce problème est particulièrement important pour les corps allongés flexibles dont la position peut varier lorsqu'ils sont soumis à des vibrations. Les constructeurs automobiles ont donc été amenés à concevoir des chemins de corps allongés présentant une bonne sécurité mais n'utilisant pas de manière optimale l'espace disponible dans le compartiment moteur.The paths of various elongated bodies must take into account not only the space available in the engine compartment, but also the proximity of hot elements such as engine parts or certain tubular pipes which risk compromising the proper functioning of fragile elongated bodies or containing cold liquids. Similarly, it may be necessary to keep the cables away from sources of electrical and / or magnetic disturbance. This problem is particularly important for flexible elongated bodies, the position of which can vary when subjected to vibrations. Automobile manufacturers have therefore been led to design elongated body paths having good security but not making optimum use of the space available in the engine compartment.

On doit également éviter à tout prix les erreurs de connexion, ce qui impose la mise en oeuvre de détrompeurs sur les connecteurs et/ou de chaînes de montage robotisées. Il est à noter que le montage sur une chaîne robotisée n'évitera pas les erreurs lors des connexions futures effectuées par des opérateurs de maintenance, par exemple lors du remplacement d'une conduite tubulaire flexible. De plus, la disposition de corps allongés dans le compartiment moteur d'un véhicule automobile compromet l'esthétique du bloc moteur.Connection errors must also be avoided at all costs, which requires the use of keying devices on connectors and / or robotic assembly lines. It should be noted that mounting on a robotic chain will not avoid errors during future connections made by maintenance operators, for example when replacing a flexible tubular pipe. In addition, the arrangement of elongated bodies in the engine compartment of a motor vehicle compromises the aesthetics of the engine block.

C'est par conséquent un but de la présente invention d'offrir un dispositif fiable d'interconnexion des divers organes d'un moteur de véhicule automobile.It is therefore an object of the present invention to provide a reliable device for interconnecting the various members of a motor vehicle engine.

C'est également un but de la présente invention d'offrir un tel dispositif permettant de réaliser des interconnexions optimisées en mettant en oeuvre des corps allongés de faibles longueurs.It is also an object of the present invention to provide such a device making it possible to produce optimized interconnections by using elongated bodies of short lengths.

C'est aussi un but de la présente invention d'offrir un dispositif d'interconnexion dont l'esthétique s'accorde avec l'esthétique du bloc moteur.It is also an object of the present invention to provide an interconnection device, the aesthetics of which matches the aesthetics of the engine block.

C'est également un but de la présente invention d'offrir un bloc moteur équipé avant son montage dans le compartiment moteur, d'un dispositif assurant au moins une partie des connexions nécessaires à son fonctionnement.It is also an object of the present invention to provide an engine block fitted before its mounting in the engine compartment, with a device ensuring at least part of the connections necessary for its operation.

Advantageously, the rigid pipes are supplemented and / or extended by flexible tubular conduits at the level of the difficult passages and / or in the zones subjected to severe stresses, in particular to vibrations. Advantageously, the chassis comprises means for fixing electrical cables, optical fiber cables and / or cable bundles.

A branch 16.31 of the pipe 16.4 is connected by a flexible tubular pipe 17.31, a rigid pipe 16.3 and a tubular pipe the flexible area 17.3 itself terminated by a quick coupling 23.3 at the outlet of a heat exchanger 27 for cooling the engine oil. The inlet of the heat exchanger 27 is connected by a flexible tubular pipe 17.2 terminated by a quick connector 23.2 to a branch 16.2 of the pipe 16.1. A heater for heating the passenger compartment of the vehicle is supplied by a pipe 16.5 connecting the water box 21 to a flexible tubular pipe 17.5 terminated by a quick connector 23.5. The return of water from the heater to the water box 21 takes place via the quick connector 23.6, the tubular pipe 17.6 and the rigid pipe 16.6. A pipe 16.7, terminated by a flexible tubular pipe 17.7, connects the box 21 to the vehicle engine intake manifold. It should be noted that the flexible tubular conduits 17.1 to 17.7 facilitate connection and assembly, avoid transmitting stresses, in particular vibrations, facilitate passage through difficult to access or tormented areas. Advantageously, the pipes 16.1 to 16.7 have a rectangular section optimizing the rigidity of the chassis according to the present invention. However, it is understood that the implementation of pipes having other geometries, in particular a different section, does not depart from the scope of the present invention. Advantageously, the flexible tubular conduits 16.1 to 16.7 have a circular section. Advantageously, the rigid pipes comprise transition zones of circular section facilitating the mounting of flexible tubular conduits.

Avantageusement, le châssis 1 selon la présente invention comporte un vase d'expansion intégré 29.Advantageously, the chassis 1 according to the present invention comprises an integrated expansion tank 29.

Le châssis selon la présente invention permet le passage des câbles nécessaires au fonctionnement du moteur, par exemple des câbles reliant le système d'allumage aux bougies du moteur, le câble reliant les générateurs électriques au système d'allumage et au démarreur. Le châssis selon la présente invention permet également de faire passer des câbles électriques ou optiques d'interconnexion du moteur avec d'autres organes du véhicule, par exemple les câbles reliant les divers capteurs de détection du bon fonctionnement du moteur au tableau de bord du véhicule.The chassis according to the present invention allows the passage of the cables necessary for the operation of the engine, for example cables connecting the ignition system to the spark plugs of the engine, the cable connecting the electric generators to the ignition system and to the starter. The chassis according to the present invention also makes it possible to pass electrical or optical cables for interconnecting the engine with other components of the vehicle, for example the cables connecting the various sensors for detecting the proper functioning of the engine to the dashboard of the vehicle. .

La présente invention s'applique principalement à l'industrie automobile.The present invention applies mainly to the automotive industry.
