Definitions

  • the present invention relates to the field of motor vehicles thermal, more particularly of automobiles, and relates to a set integrated intake manifold / throttle body for vehicles of the aforementioned type.
  • the intake manifold or air distributor and the throttle body or throttle body form two separate structural units.
  • the outlet of the throttle body being connected to the inlet or supply opening fresh air from the intake manifold through a portion of duct or connecting tube, ensuring, if necessary, also the mounting and fixing of said throttle body.
  • the constitution in two structural entities results in a significant bulk, especially in the direction of alignment of the two entities, creates a zone of mechanical weakness (connection between the two entities). which can become critical given the vibrational environment in particular, generates several dispersed sealing zones, subject to constraints mechanical, and requires separate management and supply for each of the two entities.
  • the object of the present invention is in particular to overcome the various aforementioned drawbacks.
  • an intake manifold assembly / throttle body for vehicle with thermal engine characterized in that a module passage section adjustment is reported at the opening supply of fresh air to an intake manifold so as to form a integrated intake manifold / throttle body assembly.
  • the assembly intake manifold / throttle body for vehicle with internal combustion engine produced by adding a module 2 for adjusting the passage section at the level of the opening 3 for supplying fresh air to the intake manifold 1 concerned, so as to form an integrated intake manifold / throttle body assembly.
  • the module adjustment 2 is advantageously constituted by an annular body 4 receiving a butterfly 5 mounted on a pivot axis 5 'connected to means 6, 7, 8, 9 of command and control of the rotational position of said axis 5 ', external to said annular body 4, the latter being at least partially fitted into a extension 10 in the form of a nozzle of the body of the intake manifold 1 to level of its fresh air supply opening 3 connected in particular to the air filter.
  • the command and control means may consist. through example, as shown in Figures 1 to 3. 5 and 7 of the accompanying drawings. in one valve or control sector 6 fixedly mounted on the pivot axis 5 'and connected for its drive to the accelerator pedal, in a spring of reminder 7 urging the throttle valve 5 to its minimum opening position, in one idle stop 8 defining said minimum throttle opening position 5 and in a potentiometer 9 delivering a signal or potential corresponding to the value angle of rotation of the throttle valve 5, signal or potential to the management computer of the engine operation.
  • the adjustment module 2 can be ordered mechanically (e.g. via control sector 6) or electrically (for example via a motor electric step by step).
  • the annular body 4 may include a surplus of material or a specific form of machining in line with the said pivot axis 5 '.
  • the butterfly 5 itself may have a uneven conformation, especially of different thicknesses in sections transverse or an uneven periphery, depending on the part of the butterfly 5 concerned.
  • said adjustment module 2 is advantageously immobilized in rotation relative to the intake manifold 1 by receiving external portions of the pivot axis 5 ′, or bearings of guide 5 "of said axis 5 ', in opposite cutouts 10' made in the end piece feed 10 extending outward from the feed opening 3. the fitting of the annular body 4 into said feed nozzle 10 being blocked and locked by means of an attached ring 11 secured to the body of the intake manifold 1 or said supply nozzle 10.
  • the seal between the annular body 4 of the adjustment module 2 and the body of the intake manifold 1 is produced by the interposition of a seal compression 12 between an external circumferential offset 4 ′ of the body ring 4 and an internal circumferential 10 "offset from the end piece supply 10, of complementary shapes, said seal 12 being compressed during of the fitting of said annular body 4 of the adjustment module 2 in said power nozzle 10.
  • the locking ring 11 to be secured so as to exert a constant pressure on the annular body 4 towards the socket, the areas of the surfaces in contact with the ring 11 and the body 4 being sealed, by example, via an O-ring partially housed in a groove circumferential formed in the locking ring 11 (see Figure 4).
  • Seals in particular the aforementioned O-ring and the seal 12, can either consist of independent elements reported, either in overmolded parts on one of the parts in contact (module or collector).
  • the locking ring 11 comprises a portion of tube 13 emerging at its internal wall and extending outwards, if necessary formed integrally with it, said tube portion 13 being intended to be connected to or to receive an air valve additional 14 to form a branch circuit opening into the collector admission 1.
  • the additional air valve 14 or at least the body of the latter, possibly extended by a portion of conduit opening into the intake manifold 1, may, if necessary, be made in one piece with the intake manifold 1, which will result in mechanical strength and optimized sealing ( Figures 8 and 9).
  • On the blocking ring 11 can be mounted the supply duct of air connected to the outlet of the air filter module or unit.
  • the locking ring 11 can be extended by a supply duct air 11 'made in one piece with said locking ring 11 so as to form a single piece (the locking ring 11 then constituting the end dc fixing the conduit 11 ') and connected at its opposite end to the outlet of the module of air filter (see fig. 1 of the attached drawings).
  • connection of the ring blocking 11 with the intake manifold 1 is made by means of lugs elastic hooking devices 15, formed on the locking ring 11 and engaging by engagement with external protruding recesses 16 correspondents trained on the power supply nozzle 10.
  • the locking ring 11 is provided with projecting parts peripherals 17 in the form of ears, perforated or not, and the power supply tip 10 is provided with corresponding peripheral bosses 18, perforated or not, of so as to allow their assembly by screws 19, self-tapping or not.
  • the intake manifold 1 is generally made in one thermoplastic material
  • the adjustment module 2 can be produced, as far as relates to its structural parts (in particular the annular body 4), or in one thermoplastic or thermosetting material, either aluminum.
  • the adjustment module as well as the valve additional air, will be positioned in an area outside the low point, in order to avoid problems with condensates and gels.
  • the throttle body is directly mounted in a one-piece extension of the manifold body. without implementing any connecting means (screws or the like), nor of attachment means, thus being actually integrated into it and not visible. It is locked in position by nesting on its axis or its rotational bearings in cutouts corresponding to said extension, being locked in position by tightening at by means of a fixing ring.
  • the attachment of the butterfly housing with the collector intervenes without direct mechanical fixing on the latter, but by blocking in position by clamping, also allowing compression sealing.
  • branch circuit 13, 14 is at least partially formed integrally with the manifold body and / or the clamping ring.
  • the adjustment module 2 fulfilling the functions of the housing butterfly has a simplified structure with a number of constituent elements restricted, for which the use of materials other than thermoplastics may be strongly limited.
