Turbine housing assembly

摘要

An assembly includes a cast cartridge component (205,305) and a curved wall where the cast cartridge includes a base plate (207,307) having an opening (210,310) configured for receipt of a turbine wheel, an exhaust conduit (322) having an inlet (320) and an outlet (313), a cylindrical wall (338), and vanes (334) disposed between the cylindrical wall and the base plate where adjacent vanes define throats; where the curved wall includes a proximal end and a distal end, and an upper edge and a lower edge; and where joinder of the proximal end and the outlet of the exhaust conduit, joinder of the upper edge and the cylindrical wall and joinder of the lower edge and the base plate forms a volute (350) configured to direct exhaust received via the inlet to a turbine wheel via the throats.
