Definitions

  • the invention relates to the field of exhaust gas turbochargers.
  • Exhaust gas turbochargers for supercharging internal combustion engines have in most cases at the compressor inlet on a filter silencer. These mufflers with attached filter are preferably rigidly connected by means of a mounting flange with the compressor housing. Such a connection is for example from the EP 1 186 781 A1 . Fig. 1 seen.
  • the turbocharger is attached either directly or by means of a special foot on the engine console. In most cases, the axial distance between foot and muffler is very large. Engine vibrations can cause the muffler to vibrate too high. This especially if the natural frequency of the muffler is only slightly above those of the turbocharger mounts. In this case, inadmissible vibration peaks occur at the silencer.
  • the invention is therefore an object of the invention to take measures in the attachment of the muffler to the compressor housing to prevent inadmissible vibration peaks of the muffler.
  • the muffler is rigidly secured to the compressor housing in a first connection region by means of a fastening element.
  • a second connection region of the muffler with a bearing surface on a bearing surface on the compressor housing wherein the muffler is acted upon by the support in the second connection region relative to the rigid attachment in the first connection region with a bias.
  • Fig. 1 shows a section through the air inlet side of an exhaust gas turbocharger with the compressor housing 2 and arranged at the air inlet of the compressor muffler 1. Not shown is the rotatable about an axis mounted compressor wheel and the entire turbine side of the exhaust gas turbocharger.
  • the muffler comprises a base body which carries a plurality of radially arranged sound insulation panels 11.
  • the air to be compressed is fed according to the arrows in the radial direction via a arranged on the circumference of the muffler filter 15 and between the soundproofing plates through the air inlet of the compressor.
  • the muffler is secured to the compressor housing by a plurality of circumferentially spaced bolts 3 or other suitable fasteners.
  • the screws fix the muffler both in the axial and in the radial direction with respect to the compressor housing.
  • the silencer For fastening by means of the screws, the silencer has a fastening flange 12 in the radially outer region of the housing wall 14 facing the compressor housing.
  • the compressor housing also has a corresponding mounting flange 22 in the radially outer region.
  • a support flange 13 is arranged in the radially inner region of said housing wall of the muffler. About this support flange of the muffler is axially supported on a corresponding support flange 23 on the compressor housing.
  • the support flange 13 of the muffler is axially biased relative to the mounting flange 12.
  • the muffler When mounting the muffler on the compressor housing in the axial direction, it comes first in the region of the support flanges 13 and 23 to a contact between the muffler and the compressor housing.
  • the contact region of the mounting flanges 12 and 22 there is a gap in the axial direction, which is closed only by the subsequent tightening of the screws 3.
  • the housing of the muffler between mounting and support flange according to the invention slightly warped and thereby applied to the muffler with the axial bias.
  • the support under bias has an influence on the natural frequency of the muffler.
  • a cantilevered Kragong whose natural frequency increases when it is additionally supported, increases the natural frequency of the present invention mounted on the compressor housing muffler.
  • the natural frequency of the muffler can be raised in this way compared to conventionally mounted mufflers by 30 to 60%.
  • the axial bias prevents chafing of the muffler to the compressor housing.
  • Fig. 2 a) to k) shows a selection of possible embodiments of the in Fig. 1 Dashed circled contact area between the support flange on the muffler 13 and the support flange on the compressor housing 23rd
  • the conical shaped bearing surfaces shown in b) and c) have the advantage that they are in the assembly of the muffler, the centering of the muffler with respect to the compressor housing. All of the first three embodiments are also characterized by a very simple manufacturability.
  • the embodiments d) to i) have a good sealing effect and a good joint damping. They are all different radially stepped embodiments with different costly to produce support surfaces.
  • an O-damping ring made of elastomer or another suitable material can be pressed axially.
