Definitions

  • the invention relates to an exhaust gas turbocharger.
  • An exhaust gas turbocharger or turbocharger for short is a charging system for an internal combustion engine, by means of which the cylinders of the internal combustion engine are subjected to an increased charge pressure.
  • a turbocharger consists of an exhaust gas turbine in the exhaust gas flow (Abstrompfad), which is connected via a common shaft with a compressor in the intake (Anstrompfad).
  • the turbine is set in rotation by the exhaust gas flow of the engine and thus drives the compressor.
  • the compressor increases the pressure in the intake tract of the engine, so that by this compression during the intake stroke, a larger amount of air into the cylinders of the internal combustion engine succeeded than in a conventional naturally aspirated engine. This provides more oxygen for combustion.
  • ATLs consist inter alia of a turbine housing and a compressor housing, which are both attached to a bearing housing.
  • the bearing housing has for this purpose a turbine-side flange and a compressor-side flange, wherein the turbine housing is connected by means of fastening means, preferably by screws, with the turbine-side flange. While the temperature of the Turbinengehauses can be heated by the hot exhaust gas flow depending on the speed to different high temperatures, the Lagergehause, especially by the air cooling from the compressor side, largely in the normal temperature range.
  • the screws must be made of an expensive special material to withstand the high loads.
  • the recesses for the screws for fastening the turbine housing to the bearing housing are also located in hard-to-reach places, since the bearing housing has a smaller diameter between the compressor wheel and the turbine wheel for structural reasons.
  • the fasteners must be manually screwed around the turbine housing to the bearing housing to be flanged.
  • a turbocharger for or in a motor vehicle with a compressor housing, a turbine housing and a bearing housing, with at least one compressor-side flange to provide, in which the turbine housing is frictionally connected to the bearing housing by means of a arranged on the compressor side flange fastener.
  • a bearing housing is placed on a turbine housing in a first manufacturing step, then in a further manufacturing step an inventive fastening means for fastening the turbine housing is inserted and mechanically screwed, and in a further production step a compressor housing is put on.
  • the idea underlying the present invention is to secure the turbine housing with a fastener that exerts the tension from the compressor-side flange of the bearing housing.
  • a further advantage in the use of the fastening means according to the invention is that a method for a mechanical assembly of turbochargers is provided, in which the screw head is freely accessible for the first time.
  • the production of the turbine housing can be carried out much easier and cheaper.
  • the compressor-side flange of the bearing housing has a shape for receiving the
  • the fastening means is designed as a tie rod acting screw.
  • the length of the thread of the screw is not longer than the thickness of the Turbinengehauses, and it is also advantageous that the screw in the region of the thread has a larger diameter than the shaft diameter. As a result, in the area of the high temperature load, a larger material cross-section is available to absorb the tensile force. According to another embodiment, it is advantageous if the thread of the screw is designed as a self-sealing thread. 200 626301
  • the fastening means in particular screw, has a head with internal engagement, for example a hexagon socket.
  • FIG. 1 shows a schematic representation of an inventive fastening of a turbine housing
  • FIG. 2a is a schematic elevation of an exhaust gas turbocharger with a mounting of a turbine housing according to the prior art
  • 2b is a schematic detailed representation of the attachment of a turbine housing ..
  • FIG. 2 a shows an elevation of an exhaust gas turbocharger 102 according to the prior art with a turbine 118 and a compressor 116.
  • a turbine housing 106 of the exhaust gas turbine 118 a turbine wheel 108 is rotatably mounted and connected to one end of a shaft 110.
  • a compressor wheel 104 is also rotatably mounted and connected to the other end of the shaft 110.
  • a turbine inlet 112 hot exhaust gas is admitted into the turbine 118 by an internal combustion engine, not shown here, causing the turbine wheel 118 to rotate.
  • the exhaust stream leaves the turbine 118 through a turbine outlet 114.
  • the turbine 118 drives the compressor 116 via the shaft 110 which couples the turbine wheel 108 to the compressor wheel 104.
  • the turbine housing 106 is fastened by means of a screw 107 to the turbine-side flange 123 of the bearing housing 124. 200 626301
  • the compressor housing 100 is fastened to the compressor-side flange 122 of the bearing housing 124.
  • FIG. 2b shows a schematic detailed representation of an exhaust gas turbocharger according to the prior art.
  • the turbine housing 106 is fastened by means of a short screw 107 to the turbine-side flange 123 of the bearing housing 124. Since, for design reasons, the diameter of the bearing housing 124 between the compressor-side flange 122 and the turbine-side flange 123 is substantially smaller and the bearing housing has a recess 125 for receiving the screw head, it must be manually inserted and screwed time-consuming screwing the turbine housing.
  • FIG. 1 shows a schematic representation of a mounting of a turbine housing 106 according to the invention to a bearing housing 124.
  • the turbine housing 106 which is form-fittingly attached to the turbine-side flange 123 of the bearing housing 124, encloses a turbine wheel 108 arranged on a shaft 120
  • Turbine housing 106 and bearing housing 124 is generated by means of a long screw 130 which is inserted through a recess of the compressor-side flange 122.
  • the long screw 130 designed as a tie rod, has a pretensioning in order to reliably secure the turbine housing 106 to the bearing housing 124 even at high exhaust gas temperatures.
  • the screw 130 has a threaded portion 132, which is preferably completely screwed into the turbine housing 106.
  • An advantage of the attachment according to the invention is that, by screwing the turbine housing to the compressor-side flange, the screws have a long length and the temperature difference can be split to a much greater length.
  • the mean temperature of the tie bolted connection is lower than in the case of a short screw according to the prior art. This makes it possible to use a less expensive material for the material of the screws.
  • Another advantage is that the influence of a different thermal expansion coefficient of the material of
