Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the rigid pipes are completed and / or extended by flexible tubular conduits at the level of difficult passages and / or in areas subject to severe stress, including vibrations.
  • the chassis includes means of fixing electrical cables, optical fiber cables and / or bundles of cables.
  • the chassis comprises means for fixing of measurement, regulation and / or flow control devices for fluids.
  • the invention relates to a heat engine (5) of a motor vehicle with a self-supporting interconnection frame (1) comprising an integrated expansion tank (29) and a housing (21) for inlet of distribution and outlet of water, as well as a plurality of rigid pipes elongated (16) forming with the expansion tank (29) and the housing (21) the rigid structure of the chassis (1) and extending to the proximity of the members to interconnect the motor (5), the chassis comprising fixing means (13) on the motor (5) including means for direct connection between the outlet and the water inlet for cooling the heat engine and the housing (21) of the self-supporting frame.
  • the engine chassis includes means for maintaining electrical or optical cables or other fluid transfer conduit.
  • the engine chassis has tubular lines flexible, connected to rigid pipes and ensuring connections in areas subject to severe stress, in areas of connection to engine components and / or in areas corresponding to a tormented or difficult course, and the ends of the pipes, in particular flexible tubular conduits, are provided with connection, including quick couplings.
  • Rigid pipes are made in one piece by forming or extruding plastic materials, or are carried out by assembly of several plastic parts.
  • the engine has a radiator connected to the engine by flexible tubular conduits, and by rigid pipes, in that the motor has a heat exchanger connected to the cooling via flexible tubular lines and rigid pipes, in that it comprises flexible tubular conduits and by rigid pipes connecting to the air heater the passenger compartment of the vehicle as well as a rigid pipe connected to a pipe flexible tubular connected to the intake manifold.
  • FIGS. 1a to 2b the same references have been used to designate the same elements.
  • a chassis 1 comprising a first branch 3, the 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 branches 3 and 7.
  • Branch 9 has a flange 13 for fixing the chassis 1 to the motor 5.
  • the chassis 1 according to the present invention is advantageously made of plastic, for example by extrusion blowing or rotational molding.
  • the chassis 1 according to the invention is made by assembling, in particular welding or gluing, elements obtained by molding, injection, extrusion or blow molding.
  • the rigid parts are advantageously made of plastic, although that the implementation of metal or other chassis does not go beyond the framework of the present invention.
  • Flexible tubular conduits are made of plastic or advantageously made of elastomer.
  • the fixing of flexible tubular pipes on rigid pipes is advantageously carried out by molding a plastic strap or by fitting of a collar, quick connector or other.
  • the ends of flexible tubular pipes opposite those connected to the rigid pipes of the chassis are provided with fittings fast.
  • the chassis according to the invention can be provided with means for absorbing vibrations, electromagnetic shields arranged near sources of electromagnetic interference around the cables signal transmission, and thermal insulation means arranged at proximity to heat sources, around transmission cables signal or piping.
  • the chassis 1 comprises means 15 for fixing the cables electric 19.
  • the configuration of the chassis according to the present invention is function of the motor 5 to be fitted and in particular of the device of the various members and various engine fluid inlets and outlets.
  • the output of motor pump 5 is connected to a distribution input box and water outlet 21 incorporated into the chassis according to the present invention, at the fixing element 13.
  • the housing 21 advantageously ensures the distribution hot water from engine 5 and / or water cooled in a radiator 25.
  • a rigid pipe 16.1 extended by a flexible tubular pipe 17.1 itself terminated by a fitting rapid 23.1 connects a cold water inlet from box 21 to the cold water outlet of the radiator 25.
  • a branch 16.31 of line 16.4 is connected by a tubular pipe flexible 17.31, a rigid pipe 16.3 and a flexible tubular pipe 17.3 itself terminated by a quick connector 23.3 at the outlet of a heat exchanger 27 for cooling the engine oil.
  • the entrance to 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 pipeline 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 pipe flexible tubular 17.5 terminated by a quick connector 23.5.
  • the return of water from the air heater to the water box 21 is effected by the quick coupling 23.6, the tubular pipe 17.6 and the rigid pipe 16.6.
  • Line 16.7 terminated by a flexible tubular pipe 17.7, connects the box 21 to the vehicle engine intake manifold.
  • the pipes flexible tubulars 17.1 to 17.7 facilitate connection and assembly, avoid to transmit the stresses, in particular the vibrations, facilitate the passage in difficult to access or tormented areas.
  • the pipes 16.1 to 16.7 have a rectangular section optimizing the rigidity of the chassis according to the present invention.
  • the flexible tubular conduits 17.1 to 17.7 have a circular section.
  • rigid pipes have transition zones of circular cross-section for easy assembly flexible tubular conduits.
  • the chassis 1 according to the present invention has an integrated expansion tank 29.
  • the chassis according to the present invention allows the passage of cables required for engine operation, 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 cables electrical or optical interconnection of the engine with other organs of the vehicle, for example the cables connecting the various detection sensors of the correct operation of the engine on the vehicle dashboard.
