Definitions

  • 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.
  • the paths of the 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 interference. 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.
  • 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.
  • a rigid casing comprising means for fixing to the engine block and means for fixing the elongated interconnection bodies, in particular rigid tubular conduits, flexible tubular conduits, electric cables, fibers. optics and / or cable bundles.
  • the casing includes means for attaching measuring, regulating and / or controlling the flow of fluids.
  • the main object of the invention is an interconnection casing for a thermal engine of motor vehicles, characterized in that it comprises a plurality of fixing means on the engine and means for fixing a plurality of pipes, in particular pipes. flexible tubulars, along optimized paths of interconnection of the various components of the engine and / or of the vehicle.
  • the invention also relates to a casing, characterized in that the fixing means comprise elongated profiles providing an insertion space by force of pipe, in particular flexible tubular conduits, arranged parallel to said pipes so as to ensure maintenance by snapping of the pipes on the casing.
  • the invention also relates to a housing, characterized in that it comprises means for holding electrical or optical cables or any other fluid transfer conduit.
  • the invention also relates to a housing, characterized in that it comprises an incorporated expansion vessel.
  • the invention also relates to a casing, characterized in that it comprises an incorporated water box.
  • the invention also relates to a casing, characterized in that it comprises means for connecting the pipes to the engine.
  • the invention also relates to a housing, characterized in that it comprises pipes, in particular flexible tubular conduits held by the fixing means.
  • the invention also relates to a casing, characterized in that the ends of the pipes, in particular flexible tubular conduits, are provided with quick couplings or collars.
  • the invention also relates to an engine block, characterized in that it comprises a casing according to the invention.
  • the invention also relates to an engine block, characterized in that it comprises a radiator connected to the engine by flexible tubular conduits, in that the engine comprises a heat exchanger connected by means of flexible tubular conduits, in that it comprises flexible tubular conduits for connection to the air heater for heating the passenger compartment of the vehicle as well as a flexible tubular conduit connected to the intake distributor, and in that the flexible tubular conduits are fixed by snap-fastening on the housing.
  • FIGS. 1 a to 2 b the same references have been used to designate the same elements.
  • a casing 1 comprising a first branch 3 whose length is substantially equal to the width of a motor 5 ( Figures 1b and 2b), a second branch 7 parallel to the first branch 3 and whose length is substantially equal to half the width of the motor 5, connected by a third branch 9 orthogonal to the branches 3 and 7.
  • the branches 3 and 9 carry flanges 11 respectively 13 fixing the casing 1 to the motor 5.
  • the casing 1 according to the present invention is advantageously made of plastic, for example by extrusion blow molding or thermoforming. It can be provided with means for absorbing vibrations, electromagnetic shields arranged near sources of electromagnetic disturbance, in particular around the signal transmission cables, and thermal insulation means arranged near the heat sources, around the cables. signal transmission or piping.
  • the casing 1 comprises means 15 for fixing elongated bodies, such as for example tubular conduits, preferably flexible 17 or electrical cables 19.
  • the configuration of the casing according to the present invention depends on the motor 5 to be fitted and in particular on the device of the various members and of the various inputs and outputs of the engine fluid.
  • the means 15 for fixing tubular conduits 17 comprise for example two elongated profiles partially delimiting a cylindrical channel for receiving tubular conduits. An interval between the profiles allows the passage of the pipe by force during its installation and consequently its snap-fastening. It is understood that other methods of attachment, for example by flange, by collar, by gluing or others do not depart from the scope of the present invention.
  • the pump outlet of the motor 5 is connected to a water inlet box 21 incorporated in the casing according to the present invention, at the level of the fixing element 11.
  • the water inlet box 21 is connected, on the one hand, by a flexible tubular pipe 17.1, provided at its end with a quick connector 23.1 to a radiator 25 and, on the other hand, by a flexible tubular pipe 17.2 whose the end is provided with a quick connector 23.2 at the inlet of a heat exchanger 27 for cooling the engine oil.
  • the casing 1 comprises an integrated expansion tank 29.
  • An outlet of the water / oil exchanger is connected by a flexible tubular pipe 17.3 the end of which is provided with a quick coupling 23.3 to a first inlet of the expansion vessel 29.
  • a flexible tubular pipe 17.4, one end of which is provided with a quick coupling 23.4 connects the outlet of the radiator 25 to an inlet of a water outlet housing 26.
  • the engine 5 is supplied with water cooled in the radiator 25 by a pipe situated at the level of the fixing device 11.
  • a flexible tubular pipe 17.5 terminated by a quick connector 23.5 supplies hot water to the heater for heating the passenger compartment of the vehicle, the return of water being carried out by a flexible tubular pipe 17.6 terminated by a quick connector 23.6.
  • a flexible tubular pipe 17.7 connects the degassing box integrated into the expansion tank 29 to the vehicle's intake manifold.
  • the flexible tubular lines 17.1 to 17.7 protrude from the casing 1 according to the present invention with a view to their connection to the various components of the vehicle and / or of the engine.
  • conduits having a different section such as for example conduits with a square or rectangular section.
  • the casing 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 casing 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. .
