Definitions

  • the invention relates to a device for noise transmission according to the features of independent claim 1.
  • DE 100 42 012 describes a device for designing noise in a motor vehicle known.
  • This has a hollow body which can be oscillated by at least one Membrane is divided into at least two rooms.
  • a room stands with a gas-carrying one Part of an internal combustion engine arranged in the vehicle in connection and another space is on an interior of the vehicle or on the area surrounding the vehicle Room acoustically coupled.
  • a targeted design of the noise can be by dimensioning the diameter of the different openings or Achieve membrane.
  • the structure is complex in terms of production technology and thus expensive.
  • the invention is based on the object of providing a sound transmission system that is used to design noise in a motor vehicle, inexpensively constructed can be and is easily adaptable to different requirements.
  • the main advantage of the invention is that in a closed housing a partition is arranged and this housing on the one hand with the intake pipe Internal combustion engine is connected and on the other hand with the interior of a Vehicle.
  • the partition is not rigid, but from a flap element breached.
  • This flap element only transmits sound waves, but does not lead for an air balance.
  • the flap element is mounted in such a way that the excitation optimal through the intake sound, d. H. without annoying background noises or additional noises is transmitted. In a way, it also acts as a filter for certain noise spectra hide.
  • connection of this is provided to arrange the housing with the suction pipe in the same area, which is between Turbocharger and intake valve of the internal combustion engine or between the compressor and the intake valve of the internal combustion engine.
  • the flap element is, as already mentioned, arranged sealingly on or in the partition. The reliable seal takes place via suitable sealing lips, which on the one hand allow the flap to move freely, on the other hand bring about a gas-tight seal.
  • the flap element can be removed from the surrounding housing also be spaced apart by a slight gap.
  • this gap is too choose to avoid disturbing influences from the intake air.
  • an additional membrane must be arranged.
  • Another embodiment of the invention provides the flap element on the partition to attach via an axis or a shaft, this flap element can move around a defined pivot point in a narrowly defined angular range.
  • housing consisting of a lower part and an upper part, which are connected to each other, wherein the flap element is arranged between the lower part and the upper part and a circumferential Has membrane. This membrane is clamped between the two housing parts.
  • An embodiment of this structure described with regard to the circumferential membrane provides to provide a profile seal which is at least two opposite has arranged sealing webs which engage in grooves in the partition and a Establish a tight connection.
  • FIG. 1 shows a noise transmission system with an intake pipe 10, for example arranged between the turbocharger and the intake valve of an internal combustion engine is.
  • a housing 11 is flanged to the intake pipe 10. This case is with a Partition 12 provided, this partition is broken and carries a flap 13.
  • the flap 13 is sealingly used on the opening 14 of the partition, for example via one or more sealing lips 15, or via a form-fitting in the Partition arranged shaft 16.
  • the flap 13 has a toward the housing 11 slight gap 17, so that a pressure equalization to the right side of the flap Suction pressure can take place.
  • a space 18 is located below the partition 12 which has an outlet 19.
  • This outlet is, for example, via a pipe to the Side wall of a vehicle, which separates the interior from the engine compartment or directly into the interior of the vehicle.
  • the flap 13 is also in the lower one Chamber 18 spaced from the wall 11 and can thus proceed from the Pivot 20 slightly, for example by 10 ° degrees, shown in dash-dot lines.
  • the vibration of the intake air in the intake pipe 10 is of the movably mounted Transfer flap 13 to the room 18 and continued via the outlet 19.
  • Figure 2 shows a plan view of the flap 13, for example in the assembly injection molding process is manufactured and can be integrated into the housing 11.
  • FIG. 3 shows a noise transmission system with a lower housing part 20 and an upper housing part 21.
  • the two housing parts are via fastening elements 22, such as screws. Of course there is also the possibility of welding the two housing parts together or to glue.
  • An inlet 23 is arranged in the lower housing part 20, which in connection with the intake pipe of an internal combustion engine, not shown here stands.
  • An outlet 24 is provided in the upper housing part, which is connected to the interior of a motor vehicle is connected.
  • a flap 27 is provided to separate these chambers. This has a circumferential Sealing lip 28, which seals in the connection area of the two housing halves is attached. So that this flap can transmit vibrations, it is in the middle connected via an oscillatable sealing profile 29.
  • FIG 4 shows the flap 27 with a detailed representation.
  • This flap points in the areas in which attachments are provided, holes 30 that form a positive Connection when arranging the attachments, such as elastomer parts are and are connected to the flap 27 in an injection molding process.
  • the sealing profile 29 is arranged both above and below the flap and, as in FIG 3 can be seen, each inserted in a groove 31 of the housing part.
  • FIG. 5 shows the flap mounting in a further detailed illustration.
  • the sealing profile 29 extends both into the upper groove 31 and into the lower groove 32 of the two housing parts.
  • the sealing profile is connected to the flap 27 in the injection molding process and has a tapered area 33, 34 on both sides of the flap on. This area can be designed so that the flap is suitable, certain To transmit frequencies reliably.
  • the thickness of the Sealing profile 29 for example 2 to 3 mm.
