Definitions

  • the invention relates to a distributor for a turbine of an exhaust gas turbocharger with the features of the preamble of patent claim 1.
  • the operating behavior of the exhaust-gas turbocharger is determined via an adjustment unit, a so-called distributor, or a variable exhaust-gas throttle on the turbine side.
  • the adjustment basically consists of adjustable vanes, which are pivotally mounted between two sliding plates.
  • the diffuser is usually secured by a frictional connection between the bearing housing and the turbine housing in the axial direction.
  • the nozzle is positively connected against rotation by at least one circumferential Vermospin with the turbine housing.
  • a further embodiment is known, for example, from the European patent EP 1 574 673 B1.
  • the diffuser is screwed through a hollow, exhaust-carrying central screw assembly in the turbine housing.
  • pins are provided, which are inserted into corresponding holes in the nozzle and the turbine housing.
  • a spring element is arranged between the nozzle and the turbine housing.
  • a temperature-dependent deformation of the turbine housing causes a deformation of the nozzle, which can lead to a malfunction.
  • the axial improvement of the diffuser depends on the deformation of the bearing housing, turbine housing, diffuser and its tolerance chain.
  • the axial compression of the diffuser is deformation-dependent on the bearing housing, the turbine housing and the diffuser itself, as well as their different thermal expansion coefficients.
  • the object of the present invention is o. G. To avoid disadvantages.
  • the embodiment according to claim 2 corresponds to a first particularly preferred embodiment.
  • the embodiment according to claim 3 corresponds to a second particularly preferred embodiment.
  • the embodiment according to claim 4 is an advantageous development of the second particularly preferred embodiment.
  • Fig. 1 shows a plan view of an inventive, three-dimensional illustrated nozzle.
  • Fig. 2 shows a plan view of the nozzle according to the invention, installed in a turbine housing.
  • Fig. 3 shows a section through a first, particularly preferred
  • Fig. 4 shows a section through a second, particularly preferred
  • the guide apparatus 1 consists essentially of two, spaced over four spacer bolts 4, largely annular and mutually parallel sliding walls 5, 6, between which a plurality of guide vanes 7 (three are quantified ) are arranged pivotably.
  • the distributor 1 with four screws 8 can be screwed to a bearing housing 1 "of an exhaust gas turbocharger shown in FIG. 2.
  • Fig. 3 shows a section through a first particularly preferred embodiment of an inventively designed exhaust gas turbocharger 3. Since the exhaust gas turbocharger 3 is constructed largely rotationally symmetrical, only one half is shown.
  • the distributor 1 is arranged between the turbine housing 1 'and the bearing housing 1 ", and a guide vane 7 is pivotally arranged between the turbine housing-side sliding wall 5 and the bearing housing-side sliding wall 6.
  • the guide vane 7 can be pivoted by an adjusting mechanism 14.
  • the adjusting mechanism 14 does not become since it is known from the prior art, according to the invention, the bearing housing-side sliding wall 6 is screwed to the bearing housing 1 "with the screw 8.
  • the sliding wall 6 has a through hole 9, which corresponds to a threaded bore 10 in the bearing housing 1 "Since the diffuser 1 is screwed to the bearing housing 1", in this first particularly preferred embodiment, an anti-twist protection of the guide apparatus 1 can be dispensed with.
  • the diffuser 1 is installed biased in the region of the turbine 2 by a spring element 13.
  • the spring element 13 is particularly preferably a plate spring.
  • FIG. 4 shows a section through a second particularly preferred exemplary embodiment of an exhaust gas turbocharger 3 designed according to the invention.
  • Fig. 4 shows substantially the same geometric relationships as in Fig. 3, but in this second particularly preferred embodiment, the nozzle 1 is pressed against the bearing housing 1 "via a clamping ring 11.
  • the clamping ring 11 is in Fig. 4, on base the cutting position not visible screws to the bearing housing 1 "screwed.
  • a rotation of a clamping element 12 is provided for the distributor 1, in the present second embodiment, a pin.
  • the distributor 1 can be connected directly (first embodiment) or indirectly (second embodiment) to the bearing housing 1 ".

Abstract

L'invention concerne un dispositif directeur (1) pour une roue de turbine (2) d'un turbocompresseur (3) comportant une enveloppe de turbine (1') et un logement de palier (1'') entre lesquels peut être placé le dispositif directeur (1). Ce dernier comprend deux parois de glissement (5, 6) espacées par l'intermédiaire d'au moins deux boulons d'écartement (4), sensiblement annulaires et parallèles l'une à l'autre, entre lesquelles au moins une aube directrice (7) peut être placée de manière à pouvoir pivoter. La paroi de glissement (6) orientée vers le logement de palier (1'') peut être vissée directement ou non sur ce dernier. La conception selon l'invention permet d'éviter, dans une large mesure, une déformation thermique du dispositif directeur.
