Definitions
- the invention relates to the field of exhaust gas turbochargers for supercharged internal combustion engines.
- Exhaust gas turbochargers are used to increase the performance of internal combustion engines, in particular reciprocating engines.
- an exhaust gas turbocharger usually has a centrifugal compressor and a radial or axial turbine.
- Such exhaust gas turbochargers have in most cases at the compressor inlet on a filter muffler. These silencers with attached filter are preferably rigidly connected by means of a mounting flange with the compressor housing.
- 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.
- the compressor housing is divided into many exhaust gas turbochargers in an inner and an outer housing part.
- the outer compressor housing is rigidly connected to the bearing housing or the turbine housing while the inner compressor housing for assembly or disassembly of the compressor wheel can be detached from the other housing parts.
- the connection between the inner and the outer compressor housing is usually realized by means of a screw in the radially outer region.
- a flange of the inner compressor housing with a plurality of distributed along the circumference arranged screws together with the mounting flange of the muffler to a
- the flange of the outer compressor housing is screwed tight.
- the connection of the three flanges can heat up and the vibrations cause them to be subjected to heavy loads.
- the object of the invention is to provide an optimized compressor stage for exhaust gas turbocharger applications.
- the connection between the muffler, inner and outer compressor housing to be improved.
- connections between the filter silencer and the outer compressor housing and between the inner and the outer compressor housing are realized separately.
- the two separate connections are arranged on the same flange of the outer compressor housing, but separated from each other.
- Fig. 1 shows the attachment of the filter muffler according to the prior art
- Fig. 2 shows the inventive separate attachment of filter muffler and compressor housing.
- Fig. 1 shows a portion of a compressor of an exhaust gas turbocharger with a conventional attachment of the filter muffler 2 on the compressor housing 1.
- a flange 21 of the filter muffler is screwed together with a flange of an inner compressor housing 12 to the outer compressor housing 11.
- the fastening means 31 are first inserted into holes in the outer compressor housing and screwed tight.
- only the inner compressor housing 12 is pushed with the corresponding holes and then the muffler with the corresponding holes on the fastener.
- the flanges are braced against each other by means of a nut.
- screws can be used, which are first pushed into the holes of the muffler and then through the holes of the inner compressor housing, before everything is screwed together on the outer compressor housing.
- a separate screw connection is used instead of a screw connection for both flanges.
- Both screw connections are arranged in the radially outer region of the compressor housing, in particular radially outside the compressor wheel.
- the radially inner connection between the inner compressor housing 12 and the outer compressor housing 11 is realized first during assembly. It can be worked with the tool, due to the not yet mounted silencer, on the screw connection directly in the axial direction. As fastening means 31 of this first connection optionally one or more fitting screws can be used to provide for the centering of the two housing parts.
- the second, radially outer connection between the muffler 2 and the outer compressor housing 11 is carried out according to the invention with a plurality of separate fastening means 32, which are arranged distributed along the circumference.
- long screws or expansion screws can be used for one or both connections. This leads to an improvement in the preload and to a better elasticity of the compounds.
- the screw lengths can be additionally lengthened by clamping sleeves 33.
- axial securing elements such as in the form of shear pin 4, and / or sealing elements are used.
- the number of holes of the inner and the outer connection may be the same or different.
- by increasing the number of outer bores of the muffler can be rotated during assembly relative to the outer compressor housing, and thus with respect to the entire compressor and the entire turbocharger to smaller angular units. This allows an optimal alignment of the filter silencer, for example in order to better bring out an existing license plate or to optimally position the crane point at which the filter silencer is lifted with the assembly crane.
- the alignment of the filter silencer in the radial direction can be realized either by means of a round fit or by means of dowel pins, feather keys, grooves in the flange parts or the use of dowel screws (all screws or only individual ones). Thanks to the radial orientation, a uniform inflow to the compressor can be achieved (rotational symmetry of the inlet channel). LIST OF REFERENCE NUMBERS
