Title (EN) EXHAUST-GAS TURBOCHARGER
(FR) TURBOCOMPRESSEUR DE GAZ D'ÉCHAPPEMENT
Abstract:
(EN) An exhaust-gas turbocharger (1) having a turbine (2), which has a turbine wheel (3) surrounded by an intake duct (4), and having a VTG cartridge (5), which has a washer (6) and a vane bearing ring (7), which delimit the intake duct (4), and which has a plurality of vanes (8), which are arranged in the intake duct (4) and are mounted in the vane bearing ring (7) by way of rotatable vane shafts (9), which are connected to vane levers (10), the lever heads (11) of which engage into associated grooves (12) in a unison ring (13), which surrounds the vane bearing ring (7) on the outside; and having a radial bearing between the unison ring (13) and the vane bearing ring (7), wherein the vane levers (10) for forming the radial bearing are in the form of cam levers, the lever heads (11) of which are supported in the grooves (12).
(FR) L'invention concerne un turbocompresseur de gaz d'échappement (1) ayant une turbine (2), qui a une roue de turbine (3) entourée par un conduit d'admission (4), et ayant une cartouche de géométrie de turbine variable (5), qui a une rondelle (6) et une bague de palier d'aube (7), qui délimitent le conduit d'admission (4), et qui a une pluralité d'aubes (8), qui sont disposées dans le conduit d'admission (4) et sont montées dans la bague de palier d'aube (7) au moyen d'arbres d'aube rotatifs (9), qui sont reliés à des leviers d'aube (10), dont les têtes de levier (11) viennent en prise dans des rainures associées (12) dans une bague d'unisson (13), qui entoure la bague de palier d'aube (7) sur l'extérieur ; et ayant un palier radial entre la bague d'unisson (13) et la bague de palier d'aube (7), les leviers de pale (10) pour former le palier radial étant sous la forme de leviers à came, dont les têtes de levier (11) sont supportées dans les rainures (12).
