  • a known filter of this type has a housing that one Contains filter insert and a membrane that is designed in this way is that it is caused by sound generated under certain operating conditions prevails in the housing, is vibrated and so absorbs for this sound.
  • a foam insert is glued into the housing, whereby a surface exposed to the interior of the housing Foam insert is pounded and so essentially one closed skin forms. The sound absorbing membrane is formed by this skin of the foam insert.
  • the assembly of such a foam insert requires a separate assembly step and a separate production the foam insert, which causes the formation of a such filter is relatively expensive.
  • the housing has a lattice base structure that with a sound-absorbing material is encased.
  • DE 197 47 271 A1 shows a filter in the housing Breakthrough is formed, to which a channel is connected which is closed with an acoustic membrane.
  • the channel is formed by an annular sealing element, that tightly borders the breakthrough on one end and on the other lies close to a sheet metal part of the vehicle body.
  • the membrane closing the channel is thereby this sheet metal part of the vehicle body is formed.
  • the present invention addresses the problem a filter of the type mentioned in such a way that it is relatively simple and therefore inexpensive to manufacture.
  • the invention is based on the general idea of the membrane already in the course of the manufacture of the housing in this to integrate.

  • a change also causes the rigidity or spring elasticity of the membrane a change in the damping property.
  • the construction is simplified by the construction according to the invention of the filter, since there is no additional manufacturing effort and required to install a separate membrane is.
  • the membrane in the housing separate a cavity.
  • the contained in this cavity Air acts as a spring, whose spring stiffness matches the Stiffness of the membrane is coupled, which reduces the vibration behavior and thus the damping effect of the membrane is influenced.
  • the membrane form an outer wall of the housing, which also results in a material saving.
  • a membrane designed as an outer wall of the housing their damping properties can also be influenced by that a mass element on the outside of the housing on the membrane is attached by the vibrating membrane itself can be excited to vibrate. It's clear, that the mass element is mounted or arranged so that there are relative movements or vibrations with respect to the Can run filter housing. By the type of coupling between the membrane and this mass element can also the damping effect of the membrane can be influenced.
  • the Coupling can for example be designed to be resilient and / or damping his.
  • the damping effect of Membrane are also affected by the fact that in this cavity a sound absorbing material is introduced.
  • Other Measures are seen in the fact that the housing in a Cavity associated wall section at least one opening contains through which the cavity with the surroundings of the housing communicates.
  • each filter 1 according to the Invention a filter housing 2, which a filter insert 3rd and has a membrane 4.
  • the housing 2 a raw air inlet 5 upstream of the filter insert 3 and a clean air outlet 6 downstream of the filter insert 3.
  • a filter 1 designed as an intake air filter the filter insert 3 the raw air before this an internal combustion engine is fed.
  • the membrane 4 is sound-absorbing.
  • the rigidity and / or their connection to the housing 2 selected is that prevailing in an interior 8 of the housing 2 Sound the wall or membrane 4 can excite vibrations. These vibrations are symbolic by a double arrow 9 shown. Due to the vibration excitation of the membrane 4 energy is extracted from the sound, causing the Sound emissions to the environment 7 reduced accordingly.
  • this membrane 4 i.e. their sound absorbing Effect with respect to certain frequencies or Frequency bands and the intensity of sound absorption, depends on various measures. For example, make up the rigidity or elasticity of the membrane 4 and their Mass important influencing factors.
  • the housing 2 is preferably made of several housing parts 2a and 2b and optionally 2c formed. These housing parts 2a to 2c are preferably friction welded together, these friction welded joints symbolic are shown and designated 10.
  • the membrane 4 separates Interior 8 of the housing 2 from a cavity 11, the gas volume, especially includes an air volume.
  • This closed gas volume acts like a spring with the Membrane 4 together, whereby their vibration property and thus their damping effect is influenced.
  • By choice of the volume of this cavity 11 and the one prevailing therein Pressure can dampen the effect on certain frequencies or frequency bands can be set.
  • a sound-absorbing can be in this cavity 11
  • Substance 12 can be introduced.
  • This substance 12 consists preferably of an open-cell foam or made of glass wool and causes a change in the spring properties of the air volume in the cavity 11 and thus an influence the damping effect of the membrane 4.
  • the entire Cavity 11 filled by the sound absorbing material 12 be, whereby the membrane 4 on the cavity 11 facing Side supported on the fabric 12. This measure too causes a change in the sound damping effect the membrane 4.
  • the wall section assigned to the cavity 11, here in a Bottom 13 at least one opening 14 may be included through which the cavity 11 communicates with the environment 7.
  • the present Embodiment are three openings 14 in the Bottom 13 introduced. This measure also causes a change the damping behavior of the membrane 4. It is clear that the measure shown in Fig. 4 also in the corresponding other embodiments of the other figures additionally can be used.
  • the membrane 4 in another Embodiment can also be designed so that they are does not extend over the entire cross section of the housing 2, whereby also the vibration behavior and thus the damping effect of the membrane 4 can be changed can.
  • FIG. 6 a horizontal installation the membrane 4 shows, in the embodiment according to FIG. 7 shows a vertical arrangement of the membrane 4.
  • a plurality of membranes 4 can be arranged in the housing 2, which are also different can be trained. By this measure can also affect the damping effect of the membrane assembly become.
  • the Membrane 4 an outer wall of the housing 2. Also this embodiment differs for example from that in Fig. 1 shown embodiment with regard to their damping behavior.
  • FIG. 9 shows a further development of that shown in FIG. 8 Embodiment in which a mass element 15 with the Outer wall forming membrane 4 is coupled.
  • This coupling takes place here via coupling members 16, which have a spring action and / or can have a damping effect.
