Definitions

  • the invention relates to a turbocharger in the turbine housing at least a turbine rotor is rotatably mounted, which the exhaust gas via a guide grid of variable turbine geometry is supplied.
  • variable turbine geometry is in the prior art, for example according to WO 01/96713, a wreath of nozzles of variable orientation forming vanes understood. Therefore, the guide grid has one axial boundary of a blade space forming blade bearing ring, on each of an associated shaft a plurality of adjustable around its shaft blades in the so limited vane space is stored around the turbine rotor, the exhaust over so the blades can be fed in an adjustable amount.
  • TG ring
  • the invention relates to such a trained Nozzle ring.
  • Turbocharger are within the present description also similar turbomachines, such as secondary air pumps, understood.
  • Such a turbocharger and such a blade bearing ring is for example from the EP-A-0 226 444 has become known.
  • the axial dimension of the blade space secured by spacer spacers, which screwed into the vane bearing ring must be used, which is of course a relatively complicated process.
  • the invention is based on the object, the production cost of a turbocharger or to reduce a vane bearing ring of the type mentioned, and this happens according to the invention characterized in that at least one of the two rings in the circumferential direction distributed spacers integrally formed, through which the axial distance between the two Rings is secure.
  • the spacers sit on one or the other ring or alternately on one or the other ring or in each case a half spacer the one ring is opposite to half a spacer of the other ring.
  • the spacers formed on the blade bearing ring in particular are poured, because the other ring is generally part of a larger one Section of the housing to which a spacer is more difficult to install.
  • the spacers are integrally formed so that installation costs be avoided.
  • the tolerance range can also be be reduced, so that this production brings greater accuracy.
  • one is constructively free, at best in the place of the cylindrical form of a Stiftes to choose an aerodynamically cheaper form.
  • This can preferably be done the spacers themselves have a blade shape, which shape is preferably approximately tangential is aligned.
  • a turbocharger 1 in a conventional manner a turbine housing part 2 and an associated compressor housing part 3 along an axis of rotation R are arranged.
  • the turbine housing part 2 is partially shown in section, so that a blade bearing ring 6 forming a radially outer guide grid, distributed over the circumference Guide vanes 7 about their the blade bearing ring 6 passing through pivot axes.
  • an actuating device 11 To control the movement or the position of the guide vanes 7 is an actuating device 11 provided. This can be of any nature in itself, but it is preferable if, in a conventional manner, it has a control housing 12 that controls the movement a ram member 14 attached to it controls its movement in known manner on a behind the blade bearing ring 6 (left behind in Fig. 1) the same adjusting ring 5 implement the same in a slight rotational movement.
  • This rotational movement are about the shafts 8
  • the vanes 7 in terms of their Rotary position relative to the turbine rotor 4 adjusted so that they are from an approximately tangential an extreme position in an approximately radially extending other extreme position adjustable are.
  • the exhaust gas supplied via the supply channel of an internal combustion engine more or less supplied to the turbine rotor 4, before it at the along the axis of rotation R extending axial neck 10 exits again.
  • These spacers 16 are better From Fig. 2 to see where a blade bearing ring 6 without the blades 7 stored in it you can see.
  • the spacers 16 are at regular angular intervals in the circumferential direction of the ring 6 is arranged around the rotation axis R, so that the distance to the bearing ring 15 (Fig. 1) over the entire circumference is the same size.
  • These spacers 16 are formed with the blade bearing ring 6 in one piece, preferably by a casting, in particular by investment casting, so that they with the ring 6 in the immediate shallleittagen stand. It is understood that other manufacturing processes for a one-piece part 6, 16 are conceivable, but a casting is preferred.
  • the spacers 16 could, of course, at different points of the radius of the Blade bearing ring 6 are arranged, but it is preferred if they are in the apparent Way are arranged on the peripheral edge of the ring 6. Otherwise they would have to namely be arranged in place of a corresponding vane, as shown in the US-A-4,659,295 has been proposed.
  • the spacers 16 each of a bore 18 for connecting bolt with the bearing ring 15th to enforce, so that the forces of the connection directly on the surfaces 17 of the spacers 16 act.
  • the spacers 16 in the frame the invention can obtain an aerodynamically favorable form and in particular even formed like a shovel.
  • this elongated shape is approximately in the tangential direction - relative to the Ring 6 - extends.
  • the invention is not limited to the illustrated embodiment is; For example, it can also be used for turbochargers with more than one turbine rotor 2 and / or compressor rotor 21 or with more than one feed channel 9 applied become. Moreover, it would be conceivable not to provide all spacers 16 with bores 18, in particular, if more than three spacers 16 should be provided, for example six. Instead of the blade bearing ring 6 together with the spacers 16 by To produce casting, the apparent from Fig. 2 surface, for example, could also obtained by extrusion, as for other fluid flowed through car components has already been proposed.
