Definitions

  • the invention relates to a soundproofing lining for covers of noise sources, for. B. engines, compressors and. Like., Having a sound insulation layer provided on the noise source side with a cover layer.
  • Sound-absorbing linings which consist of a rubber or plastic layer on the noise source side, which covers a sound insulation layer made of foam or other materials. It is often necessary to provide fastening elements for hose and pipe lines, electrical cables or the like to be provided on such a sound-absorbing lining. Since the rubber or plastic layer of the sound-absorbing lining does not have enough mechanical strength to allow the attachment of raw clamps, cable clamps or the like. These are directly through the lining through on the cover, for. B. the hood of a vehicle attached. This attachment can be done, for example, by screws, rivets or the like.
  • the object of the invention is therefore to find a solution in a lining of the type mentioned at the outset, which is op is timal and also requires little production effort.
  • the embedding of such an organ between the sound insulation layer and the cover layer leads to a "floating" fastening of the pipe clamps, cable clamps or the like, so that no vibration transmission and thus noise transmission to the cover itself can take place under the action of vibrations.
  • the second aim of the invention namely a rational production method, is achieved in that the organ is simply applied in the manufacture of the sound-absorbing lining, before the covering layer is applied to the sound-insulating layer, and is subsequently held in place by the applied covering layer, without additional production outlay.
  • another feature of the invention provides that the organ is a threaded bushing, nut or the like.
  • this embodiment will be selected if the object to be fastened has a relatively low weight and its positioning is flexible within certain limits.
  • a useful embodiment of the invention is that the organ is a plate made of metal, plastic, wood or the like. This has the advantage that there is a certain degree of freedom for the attachment of the object, so that its actual attachment position to the installation situation of the cover, for. B. the hood, be specially adapted on the spot can; further the further advantage that the plate does not have to be positioned exactly, which is another advantage for the production.
  • the subsequent attachment of the object to a plate serving as an organ is further facilitated in that the plate has pre-drilled holes. It is particularly expedient if the holes are distributed in a regular arrangement over the plate, because great flexibility in the positioning of the object to be fastened can then be achieved.
  • Another advantage of using a plate as an organ is that it distributes the tensile forces over a larger area of the cover layer and thus also heavier objects are safely held without the risk of tearing out or damaging the soundproofing lining as a whole.
  • a cover 1 for example a bonnet
  • a sound-absorbing layer 2 which in turn consists of a rubber layer 4, which is adhered to the cover 1, and a foam pad 5.
  • a cover layer 3 which covers a plate 6, the latter thus being embedded between the cover layer 3 and the foam pad 5.
  • the plate 6 has holes 7 which serve to receive mechanical fastening means, for example screws, with the aid of which a pipe clamp, cable clamp or the like can be fastened.
  • the rubber layers are preferably made of self-vulcanizing rubber materials at room temperature within two to three weeks, which improve the sound absorption effect with heavy filling substances, for example chalk, barium sulfate or the like, are filled.
  • Polyurethane composite foam is often used as the foam pad, which is a foam that is produced by connecting flexible polyurethane foam flakes with simultaneous compression. The density of such flake composite foams can be adjusted as desired and is between 200 and 400 g / dm 3 for the present purpose .
  • Masticated natural rubber and / or natural rubber / nitrile rubber blends can be used as the rubber.
  • a suitable amount of filler can be incorporated into the rubber by means of suitable plasticizer and reinforcing additives, and the required resistance to oil, petrol and cleaning agents can also be achieved by choosing the suitable rubber.
