Definitions

  • the invention relates to a housing for a component of an exhaust system, in particular for an exhaust gas purification device.
  • the invention also relates to a method for producing a housing for a component of an exhaust system.
  • the component may in particular be a diesel particulate filter or a catalyst. These are mounted together with a bearing mat inside the housing. Recently, a manufacturing method which is commonly referred to as “calibration” is often used. In this method, the housing is provided with a circumferentially closed shell, then inserted the component with the bearing mat in the shell and then compressed the jacket in the radial direction until the component is held with the bearing mat with the desired pressure inside the housing. This process is also known as “shrinking". In modern shrink method while the jacket is individually geshrinkt each, so taking into account the individual dimensions of the component and the bearing mat. As a result, the diameter of the geshrinkten housing varies within certain limits.
  • an inlet cone and an outlet cone is usually mounted upstream and downstream of the housing. Since these are always provided with the same diameter, it is provided in modern shrink method to calibrate the axial ends of the housing for the component after shrinking so that the housing always has the same diameter at least at its axial ends, regardless of individual Shrink. This process is very complicated on the whole.
  • the object of the invention is to provide a housing for a component of an exhaust system, which makes it possible to connect with less effort an inlet cone or an outlet cone.
  • the object of the invention is also to provide a method for the simplified production of such a housing.
  • a housing for a component of an exhaust system is provided according to the invention, in particular for an exhaust gas purification device, with the features of claim 1.
  • the steps are provided according to claim 6.
  • the invention is based on the surprising finding that when the jacket is shrunk only in a central region and a short section at the axial ends of the shell remains unprocessed, the diameter and also the angle of these unprocessed portions to only a very small extent of the diameter of depends on the central area.
  • the jacket when the component is accommodated in the interior of the housing, the jacket ends approximately flush with the component in the axial direction.
  • the jacket can be made shorter than in the prior art.
  • the jacket In the prior art, the jacket must project beyond the component in the axial direction, otherwise the axial ends of the jacket can not be calibrated.
  • the invention takes into account the recognition that the diameter of the shell at the axial ends, when the clamping portion is shrunk, increases, so that there is sufficient space for receiving the input cone or the output cone available. This is insofar. Surprisingly, when the diameter at the axial end of the shell changes in exactly the opposite direction as the diameter of the clamping portion.
  • FIG. 1 a housing 10 can be seen, which consists of a jacket 12 and two connecting parts 14, of which only one is shown here.
  • the connecting parts are an inlet cone or an outlet cone, with which the housing can be connected to an exhaust system of an internal combustion engine.
  • a component 16 of the exhaust system is arranged, in particular a diesel particulate filter or a catalyst.
  • the component 16 is surrounded by a bearing mat 18:
  • the jacket 12 In the initial state, ie before the attachment of the component 16, the jacket 12 has a diameter DA (see FIG. 3 ), wherein the sheath does not necessarily have to have a circular cross section, but also may have an oval, triovalen or other cross section.
  • the shell 12 is in the initial state with a length L beyond a clamping portion 20 in which a shrink tool 22 engages the shell and this upsets in the radial direction. Due to the compression of the jacket in the region of the clamping section, the diameter is there to the final diameter DE (see again FIG. 3 ), so that the component 16 is held together with the bearing mat 18 firmly in the interior of the shell.
  • the final diameter DE is matched to the respective diameter of the component 16. It is noteworthy, however, that changes in the final diameter DE lead only to a negligible extent to changes in the diameter of the connecting portion 26 and the angle ⁇ .
  • changes in the final diameter DE lead only to a negligible extent to changes in the diameter of the connecting portion 26 and the angle ⁇ .
  • the length L with which the jacket protrudes beyond the shrinking tool 22 in the initial state, was varied between 15 and 24 mm.
  • a standard connection part 14 can be attached to each individually jacketed jacket 12. This can, for example, as in the FIGS. 1 and 2 can be seen to have a tapered terminal portion 15 which is inserted into the connecting portion 26. Subsequently, the jacket 12 and the connecting part 14 can be connected to each other, for example, welded or soldered.
