Turbine for exhaust gas turbocharger, has guide blade held by turbine housing, and contour sleeve influencing flow parameters within turbine wheel inlet area, where guide blade and contour sleeve are formed as single piece

摘要

The turbine (10) has a guide blade (16) held by a turbine housing (12). A contour sleeve (20) influences flow parameters within a turbine wheel inlet area (18), where the contour sleeve and the guide blade are formed as a single piece. A component assembly inserts the guide blade, the contour sleeve and an axial slider (24) for influencing a flow cross section of the guide blade into the turbine housing. The contour sleeve exhibits a front side area (32) perpendicular to a turbine longitudinal axis (30), and is connected with the guide blade over the longitudinal axis. An independent claim is also included for a method for manufacturing a turbine for an exhaust gas turbocharger.
