Definitions

  • the invention relates to an exhaust-gas turbocharger according to the preamble of claim 1.
  • An exhaust-gas turbocharger of said type is known from DE 10 2007 024 130 Al .
  • the turbine housing of this exhaust-gas turbocharger has a metallic outer shell, which is provided with an inner shell made of a ceramic material, wherein a soft intermediate layer is introduced between the outer shell and the inner shell.
  • the outer shell, the inner shell or both shells can have a multi-part design. This is intended to have the effect that the inner shell can be inserted into a geometry of the turbine housing, the inner cavities of which are larger than the openings of the housing.
  • the intermediate layer is needed in order to make it possible to compensate for different thermal expansion properties of the inner and outer shells.
  • the exhaust-gas turbocharger according to the invention has an internal insulation, which makes it possible to achieve an improved warm-up behavior, an increased exhaust-gas enthalpy before the turbine and also an increased exhaust-gas temperature before a catalytic converter entry.
  • the introduction of heat into an engine space in which the exhaust-gas turbocharger is installed can be reduced with the exhaust-gas turbocharger according to the invention.
  • the inner shell of the exhaust-gas turbocharger according to the invention has an insulating action, and at the same time is matched in terms of its thermal expansion properties to the metallic outer shell which encloses it, it is not necessary to provide an intermediate layer between the outer shell and the inner shell.
  • the component parts of the ceramic inner shell, in the form of the compressor spiral insert and the contour insert, are preformed ceramic bodies and can accordingly be used as solid insert bodies for a casting process for the metallic outer shell of the turbine housing according to the invention, as integral component parts of this production method.
  • the ceramic contour insert or nozzle ring is preferably produced from partially stabilized zirconium oxide and accordingly has an insulating effect and is dimensionally stable and resistant to erosion.
  • the zirconium oxide can be stabilized by yttrium. As a result, the zirconium oxide becomes less brittle.
  • the nozzle ring can directly bear the flange of the exhaust-gas system to which the exhaust-gas turbocharger is connected.
  • Claims 6 and 7 define the turbine housing according to the invention as an object which can be marketed independently.
  • Claims 8 to 10 define a method for producing a turbine housing according to the invention.
  • Figure 1 shows a schematically greatly simplified illustration of an exhaust-gas turbocharger according to the invention
  • Figure 2 shows a sectional illustration through an embodiment of a turbine housing according to the invention
  • Figure 3 shows a plan view of the turbine housing outlet from the direction of a contour insert
  • Figure 4 shows a sectional illustration, corresponding to Figure 2, of a further embodiment of a turbine housing according to the invention.
  • Figure 1 shows a schematically greatly simplified illustration of an exhaust-gas turbocharger 1, which can be formed in the manner according to the invention as explained above.
  • the exhaust-gas turbocharger 1 has a turbine housing 2, in which a turbine wheel 8 is arranged.
  • a shaft 9 is mounted in a bearing housing 10, which is connected to the turbine housing 2, and at one of its ends bears the turbine wheel 8 and at its other end bears a compressor wheel 12, which is arranged in a compressor housing 11 likewise connected to the bearing housing 10.
  • FIG. 2 shows a sectional illustration through the turbine housing 2 according to the invention.
  • the turbine housing 2 has a metallic outer shell, denoted in its entirety by reference sign 3.
  • a ceramic inner shell, denoted in its entirety by reference sign 4, is arranged in this outer shell 3, and bears directly, i.e. without the provision of any intermediate layer, against the inside of the outer shell 3, as can clearly be seen from the illustrative representation in Figure 2.
  • the outer shell 3 comprises a spiral region 5, a contour region 6 and a turbine housing outlet 7 adjoining the contour region 6.
  • a ceramic compressor spiral insert 4A made up of a ceramic consisting of aluminum titanate is arranged in the spiral region 5. As has been mentioned, this compressor spiral insert 4A bears directly against the inner wall of the spiral region 5, and lines it completely on the inside.
  • a dimensionally stable ceramic body consisting of zirconium oxide is arranged in the contour region 6 as a contour insert 4B, which similarly bears directly against the inner wall of the contour region 6 and lines it completely on the inside.
  • the contour insert 4B as a dimensionally stable ceramic body, bears a flange 13 over the metallic turbine housing outlet 7 adjoining the contour region 6, it being possible for said flange to be in the form of part of an exhaust-gas system to which the exhaust-gas turbocharger 1 according to the invention is fitted.
  • FIG 4 shows a further embodiment of a turbine housing 7', which corresponds substantially to that of the embodiment shown in Figure 2.
  • a turbine housing 7' which corresponds substantially to that of the embodiment shown in Figure 2.
  • Figure 4 shows an embodiment of the turbine housing 7' in which the contour insert 4B' forms a flange 13' of the turbine housing 7' in the contour region 6'.
