Definitions

  • the invention relates to the field of supercharged internal combustion engines. It relates to an air inlet housing, in particular a filter silencer or an air intake, a compressor of an exhaust gas turbocharger and a compressor with such an air inlet housing.
  • Turbochargers have an air inlet housing. This is usually either a filter silencer or an air suction. Which variant is used differs depending on the cable routing on the motor and is determined by the motor manufacturer. From the manufacturers of the turbocharger usually both air intake variants are offered for the same type of turbocharger.
  • the object of the present invention is to optimize the inflow region of the compressor of an exhaust gas turbocharger to the effect that the structural load can be minimized in case of bursting while maintaining a high quality of the flow.
  • this is achieved by local weakening of the inlet cone on the air inlet housing in the potential contact area to the insert wall of the compressor by external, axially guided notches.
  • the notches are introduced from the outside into the inlet cone to a residual depth, so that the wall of the inlet cone, which delimits the flow channel to the outside, remains intact from the inside.
  • predetermined breaking points are thus formed, which give way under load.
  • the compressive stresses caused by the impact lead to breakage of at least one of the predetermined breaking points, whereby the continuous annular cross section is canceled in the exit plane of the air inlet housing.
  • the compressive stresses can no longer be distributed over the annular cross-section of the inlet cone interrupted by the at least one breakage point. It comes to the failure and breaking out of individual segments of the inlet cone.
  • breaking off individual limited by predetermined breaking points segments from the inlet cone of the transmitted to the entire air inlet housing axial pulse is reduced by energy is dissipated by deformation and sufficient path for the deformation of the wall insert is provided.
  • the turbine wheel is arranged at one end of a rotatable about the axis A turbocharger shaft, which is rotatably mounted in the bearing housing 40.
  • the compressor wheel At the other end of the turbocharger shaft is the compressor wheel, which compresses air drawn in through the air inlet 11, which is subsequently collected in a spiral or collector housing and fed via the air outlet 12 to the combustion chambers of the internal combustion engine.
  • the air can be supplied to the intake area of the compressor via a tubular air intake 22 (in the Fig. 1 indicated in the left half above the axis A) or via a silencer 21 (in the Fig. 1 in the left half below the axis A indicated) are supplied.
  • the muffler may additionally comprise filter elements which prevent the entry of larger particles in prevent the compressor. In this case, we talk about a filter silencer.
  • Fig. 2 shows the cylindrical base body 210 of a filter muffler without inserted damping elements and without attached filter element.
  • the main body is either a monobloc (casting) or a component composed of several individual parts.
  • the base body has a closed end-side front wall 211 and a rear wall 212 with a central air outlet opening 213.
  • To the lateral surface of the cylindrical body is usually a filter element through which the air flows into the interior of the filter muffler and there approximately in the radial direction along the grooves provided in 214 arranged damping elements in a central cavity.
  • the inlet cone 24 on the air inlet housing 2 is weakened locally targeted in the potential contact area to the wall of the compressor by external, axially guided notches 25.
  • the notches are introduced up to a residual wall thickness b from the outside into the inlet cone 24 with the wall thickness a, so that the flow channel S outwardly bounding wall of the inlet cone from the inside remains intact. In the region of the notches, predetermined breaking points are thus formed, which give way under load.
  • the compressive stresses can no longer be distributed over the annular cross-section of the inlet cone interrupted by the at least one breakage point. It comes to the failure and breaking out of individual segments of the inlet cone.
  • breaking off individual limited by predetermined breaking points segments from the inlet cone of the transmitted to the entire air inlet housing axial pulse is reduced by energy is dissipated by deformation and sufficient path for the deformation of the insert wall is provided.
