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 a interconnection device, in particular hydraulic and pneumatic for various components 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 circuits, hydraulic and electrical connecting various engine components together as well as external devices. When mounting the vehicle or its maintenance, it is therefore imperative to ensure the passage and connection of numerous 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 space available in the engine compartment, but also the proximity of hot elements such as engine parts or certain tubular pipes which could compromise the correct operation of fragile elongated bodies or bodies containing cold liquids. Likewise, cables may need to be kept away from electrical and / or magnetic disturbance. This problem is particularly important for flexible elongated bodies whose position can vary when subjected to vibrations. Car manufacturers have therefore had to design elongated body paths having a good security but not optimally using the available space 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 chaínes de montage robotisées. Il est à noter que le montage sur une chaíne 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 should also be avoided at all costs, which imposes the implementation of polarizers on the connectors and / or robotic assembly lines. It should be noted that mounting on a chain robot 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 offer a reliable device for interconnecting the various components of a motor motor vehicle.
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 offer such a device for achieving optimized interconnections by works 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 a device interconnection whose aesthetics match 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 a engine block fitted, before mounting in the engine compartment, with a device ensuring at least part of the connections necessary for its operation.
Ces buts sont atteints selon l'invention par des canalisations rigides assemblées de manière à former un châssis autoportant d'interconnexion. Avantageusement, les canalisations rigides sont complétées et/ou prolongées par des conduites tubulaires flexibles au niveau des passages difficiles et/ou dans les zones soumises à des sollicitations sévères, notamment à des vibrations. Avantageusement, le châssis comporte des moyens de fixation des câbles électriques, des câbles à fibres optiques et/ou des faisceaux de câbles.These objects are achieved according to the invention by pipes rigid assembled to form a self-supporting frame interconnection.

de la présente invention. Les conduites tubulaires flexibles sont réalisées en
matière plastique ou avantageusement en élastomère. La fixation de
conduites tubulaires flexibles sur les canalisations rigides est

tubulaires flexibles 17.1 à 17.7 facilitent la connexion et le montage, évitent
de transmettre les sollicitations, notamment les vibrations, facilitent le
passage dans des zones difficilement accessibles ou tourmentées.
