Definitions

  • the invention relates to a component for noise insulation, in particular for use in vehicle construction, for. B. oil pan and cover plate.
  • housings which reduce the noise generated by the unit.
  • Such components are known from transmission and engine construction, z. B. gearbox are built to reduce noise.
  • the noise insulation is implemented according to the prior art in that the housing consists of two metallic layers, for example sheets, which are connected to one another by a plastic layer. This means that such a housing is essentially of three layers.
  • a disadvantage of such a housing is that the plastic intermediate layer, such components can only be used where temperatures above 130 ° to 140 ° do not occur, since otherwise the plastic intermediate layer melts, with the result that the noise insulation is greatly reduced.
  • the invention is therefore based on the object of providing a component for noise insulation which can also be used in units which operate in the high temperature range.
  • the object is achieved by at least two metallic layers, for example metal sheets, which are arranged one above the other and in particular have a different thickness.
  • a component can also be used up to temperatures of around 500 ° C.
  • noise insulation can be achieved in this way, which can also be achieved with the three-layer component known from the prior art.
  • the two layers each have a different natural frequency due to the different thickness, which leads to the destruction of the resulting frequencies.
  • at least one of the two layers has a coating, for example made of aluminum, which is applied to the side facing the other layer.
  • the two layers are directly connected to one another, for example by pressure joining. Pressure joining is understood to mean caulking the components, pressure joining having the advantage that damage to the surfaces is largely avoided. If damage to the surfaces can be avoided, there is also no risk of corrosion between the two layers forming the component.
