Definitions

  • the invention relates to a turbocharger according to the preamble of claim 1.
  • Such a turbocharger is from the EP 1 564 380 A1 known.
  • this document proposes a stop which is integrally connected to the adjusting ring.
  • the projection of the stop of the known turbocharger limits the end positions by contact with mounting rings of the adjusting lever on the blades, which also makes precise adjustment of the end positions difficult, since the mounting rings of these blade adjustment levers are subject to manufacturing tolerances and on the other hand, due to the positioning (division) inaccuracies arise.
  • turbocharger specified in the preamble of claim 1 way, which allows a simplification of the assembly of the guide grid or diffuser, at least a simple and accurate adjustment of the minimum flow through the diffuser should be possible alone.
  • the stop with which at least one setting of the minimum flow through the nozzle cross-sections formed by the vanes is possible, is formed as a separate component which is fixable in the guide grid, it is possible after mounting the guide grid this stop in a simple way and way to rework the exact setting of the required stop position, since it is not integrally connected to the guide grid. If the need for a readjustment of one of the two end positions of the guide grid, it can be either simply selected and mounted a suitable fitment for the desired end position or adapted the intended stop member by reworking the projection and then mounted in the guide grille. Thus, it is possible to make a precise end position targeted, which is problematic in the generic turbocharger due to the integral formation of the stop.
  • the entire diffuser can be completely pre-assembled as a cartridge and the minimum flow can be adjusted before it is then inserted into the turbine housing.
  • the adjustment of the minimum flow is thus independent of turbine housing and other components of the turbocharger, such as e.g. the bearing housing. Also, the nozzle position between the bearing and turbine housing no longer has any influence on the minimum flow setting. Also, the wear of the adjusting lever and its engagement with the adjusting ring does not affect the minimum flow rate.
  • a guide grid is defined as each independently tradable objects.
  • FIG. 1 an inventive turbocharger 1 is shown, which has a turbine housing 2 and a compressor housing 3 connected thereto via a bearing housing 19.
  • the housings 2, 3 and 19 are arranged along a rotation axis R.
  • the turbine housing 2 is shown partially in section to illustrate the arrangement of a vane ring 6 as part of a radially outer baffle 18 having a plurality of circumferentially spaced vanes 7 with pivot shafts 8.
  • nozzle cross sections are formed, which are larger or smaller depending on the position of the guide vanes 7 and more or less applied to the turbine rotor 4 mounted in the middle on the axis of rotation R with the supplied via a feed channel 9 and discharged via a central port 10 exhaust gas of an engine to drive over the turbine rotor 4 a seated on the same shaft compressor rotor 17.
  • an actuating device 11 is provided.
  • This can be designed to be arbitrary, but a preferred embodiment, a control housing 12, which controls the control movement of a ram member 14 attached to her to implement the movement thereof to a located behind the blade bearing ring 6 adjusting 5 in a slight rotational movement of the same.
  • a clearance 13 for the vanes 7 is formed between the vane ring 6 and an annular part 15 of the turbine housing 2.
  • the blade bearing ring 6 has integrally formed spacers 16.
  • three spacers 16 are arranged at an angular distance of 120 ° in each case on the circumference of the blade bearing ring 6. In principle, it is However, it is possible to provide more or less such spacers 16.
  • Fig. 2 is a partial perspective view of a first embodiment of the guide grid 18 according to the invention shown on an enlarged scale.
  • a blade lever 20 is shown having at one end a mounting ring 21 with a recess 22 in which one end of the blade shaft 8 is fixed.
  • a lever head 23 of the blade lever 20 is disposed in an engagement recess 24 of the adjusting ring 5 and thus is engaged with the adjusting ring 5 in engagement.
  • FIG. 2 the arrangement of a stop 25 in the form of a separate component.
  • the stop 25 has a stop body 26, which has been fixed in the illustrated embodiment on the blade bearing ring 6.
  • the stopper body 6 has a radially outwardly projecting projection 27, which engages in a groove 31 of the adjusting ring 5.
  • the groove 31 of the adjusting ring 5 is bounded by two stop cams 29 and 30.
  • the stop cams 29 and 30 have inwardly into the groove 31 facing abutment abutment surfaces which can engage with the corresponding adjacent surface of the projection 27.
  • a stop position on the stop cam 29 for adjusting the minimum flow through the nozzle cross sections of the guide grid 18 is shown.
  • a stop web 28 is arranged at the upper end of a side facing the stop cam 29 side surface 34 which extends at right angles to the side surface 34.
  • This stop bar 28 can be reworked for exact position adjustment in case of need, should In the course of the assembly of the guide grid 18 it turns out that the exact position can not yet be set.
  • the stop 25 can then be separated from the blade bearing ring 6 and be reworked in a precision device by removing a suitable portion of the stop web 28.
  • Fig. 3 a second embodiment of the guide grid 18 according to the invention is shown.
  • all parts that are those of Fig. 2 provided with the same reference numerals, so that reference can be made in terms of training and function to the above description.
  • the stop 25 of the second embodiment is provided with an adjusting plate 32.
  • the adjusting plate 32 has a fixing plate 35 which can be fixed to the stopper body 26, such as by a Fixierclip 36.
  • Fixierclip 36 any other types of mounting options for the adjusting plate 32 on the stopper body 26 are conceivable.
  • the adjusting plate 32 is provided with a stop plate 33 in the second embodiment, which extends parallel to the side surface 34 of the projection 27 and to this one Fig. 3 apparent distance, so as to be able to define the exact stop position.
  • the stop position can be effected by the replacement of the adjusting plate 32, so that in this embodiment, an exact adjustment, in particular the minimum flow, in a simple and cost-effective manner is possible.
