Definitions

  • Burst protection device for radial compressors of turbochargers
  • the invention relates to a burst protection device for a radial compressor of a turbocharger, as described by the features of the preamble of claim 1, and to a turbocharger according to the features of the preamble of claim 10.
  • this In addition to the large force acting in the radial direction, this also creates a large force acting in the axial direction.
  • This force acting in the axial direction is transmitted through the insert wall to the compressor housing and further to the connection between the compressor housing and an upstream component, such as an intake manifold or a filter silencer.
  • an upstream component such as an intake manifold or a filter silencer.
  • the connection between the compressor housing and the upstream which is usually a screw connection, cannot withstand these large axial forces and parts of the compressor housing and the upstream component are thrown away axially.
  • the above-mentioned measures cannot counteract the danger to people and neighboring facilities.
  • the object of the present invention is therefore to provide a turbocharger with a radial compressor, in which, in the event of a compressor bursting, axial throwing away of housing parts or parts fastened to the compressor housing is prevented.
  • the burst protection device according to the invention for a radial compressor of a turbocharger has a flow channel which is delimited radially outwards by an insert wall above the rotor blades of the compressor wheel.
  • the insert wall has a predetermined breaking point above the blades or further downstream. In the event of a compressor wheel bursting, part of the axial forces are absorbed by the controlled breaking of the insert wall at the predetermined breaking point.
  • the connection between the compressor housing and the upstream component is not destroyed and the individual parts can no longer be thrown axially.
  • the predetermined breaking point is preferably designed in the form of a notch. This is easy to manufacture, inexpensive and allows a very defined break in the insert wall
  • the predetermined breaking point is arranged in the area between the rotor blades of the compressor wheel and adjacent guide vanes of a compressor diffuser. This arrangement of the predetermined breaking point leads to the absorption of the major part of the axial energy in the breaking off part of the insert wall.
  • the insert wall is radially surrounded by an inner wall of the compressor housing, which has at least a first section that tapers conically upstream, this section starting approximately at the level of the predetermined breaking point of the insert wall and having an initial radius there that is approximately the same size or is slightly larger than the radius of the insert wall at the predetermined breaking point.
  • the breaking off part of the insert wall which moves in the axial direction due to the absorption of a large part of the axial, kinetic energy, is braked in its axial movement by this conically tapering upstream axial section of the inner wall. By deforming this section of the inner wall and by friction losses, axial kinetic energy is destroyed.
  • brake elements projecting radially outward from the insert wall are provided, which in the case of the compressor wheel only interact with further conically tapering sections of the inner wall. This means that axial, kinetic energy, which is stored in the broken-off part of the insert wall, can be destroyed at the same time by friction and by deformation of the inner wall.
  • one or more of the conically tapering sections as brake lugs protruding radially inwards from the inner wall.
  • the brake lugs can be deformed without this having a deforming effect on the adjacent conical sections.
  • FIG. 1 shows in section along its machine axis a part of a compressor side of a turbocharger with a radial compressor according to the prior art

  • FIG. 3 analogous to the illustration in FIG. 2, a further embodiment of the burst protection device according to the invention.
  • FIG. 1 shows in section along its machine axis 10 a section of a turbocharger with a radial compressor 12 on the compressor side.
  • the radial compressor 12 has a compressor wheel 14 with rotor blades 16 mounted on a shaft 13.
  • the blades 16 protrude into a flow channel, which is marked by arrows 18.
  • This flow channel 18 is delimited radially outwards by an insert wall 20, at least in the area above the moving blades 16.
  • the compressor diffuser 22 has guide vanes 40 and is connected by means of a screw 23 on the one hand to the insert wall 20 and on the other hand to a compressor housing 24 surrounding the compressor wheel 14.
  • the compressor housing 14 has an outer housing part 26 and an inner wall 28.
  • the inner wall 28 connects directly to the radially extending region of the insert wall 20 and radially surrounds the axially extending region of the insert wall 20.
  • the compressor housing 24 is on the gas inlet side by means of a connection 30, which is designed here in the form of a screw connection, connected to an upstream component 32.
  • This upstream component 32 can be, for example, an intake manif
  • the compressor wheel 14 acts like a wedge between the compressor diffuser 22 and the insert wall 20.
  • the large axial forces thus generated are transmitted through the insert wall 20 to the inner wall 28 and further to the connection 30. If the axial forces are too great, the connection 30 does not withstand the sudden load and the upstream component 32 and the inner wall 28 and the insert wall 20 are thrown away axially.
  • turbocharger 12 with the compressor wheel 14, the moving blades 16, the insert wall 20, the compressor diffuser 22 and the compressor housing 24, 26, 28 together with the upstream component 32 is basically of the same construction, as shown in the turbocharger from the prior art in FIG. 1
  • the turbocharger according to the invention for the radial compressor 12 has a burst protection device 34 which prevents the housing parts 28, the insert wall 20 and upstream components 32 from being thrown axially away.
  • the burst protection device 34 comprises the insert wall 20, which delimits the flow channel 18 radially outward over the rotor blades 16 of the compressor wheel 14, the Insert wall has a predetermined breaking point 36.
  • this predetermined breaking point 36 is arranged in the area 38 between the axially and the radially extending area of the insert wall 20, specifically between the rotor blades 16 of the compressor wheel 14 and the guide blades 40 of the compressor diffuser 22.
  • the inner wall 28 has, in its part adjoining the radially extending region of the insert wall 20, an initial radius Ra which is approximately as large or slightly larger than the radius Re of the insert wall 20 in the region of the predetermined breaking point 36
  • Inner wall 28 in a first conically tapering section 42 with an incline of approximately 5 °.
  • the inner wall 28 tapers with an incline of approximately 40 °.
  • conically tapering sections 46 of the inner wall 28 which cooperate with brake elements 48 projecting radially outward from the insert wall 20.
  • FIG. 3 shows a further embodiment of the burst protection device 34 according to the invention, in which a plurality of the sections 44, 46 tapering conically upstream are designed as brake lugs 50 projecting radially inwards from the inner wall 28.
  • the predetermined breaking point 36 can also be arranged at another location in the area above the blades, between the axially and the radially extending area of the insert wall 20 or even in the upstream area of the radially extending area of the insert wall 20. If not too great axial forces are expected, it is possible to provide only the predetermined breaking point 36 in the insert wall 20.
  • the conical slopes of the inner wall can be approximately in the range between 5 ° and 30 ° for the first section 42 and approximately in the range between 5 ° and 50 ° in the further sections 44, 46.
  • Brake elements 48 and brake lugs 50 are preferably formed in one piece with the insert wall 20 or with the inner wall 28, as shown in FIGS. 2 and 3. But they can also be designed as separate components.
