Abstract
A variable turbine geometry assembly is provided for controlling flow of exhaust gas to a turbine wheel of a turbocharger. The variable turbine geometry assembly includes a base structure, vanes, vane levers, and an adjustment ring. The vanes are distributed circumferentially around the base structure and are pivotable relative to the base structure to vary an effective inlet area. The vane levers are for pivoting the vanes. The vane levers each include an inner portion coupled to one of the vanes and an outer portion extending from the inner portion. The adjustment ring is selectively rotatable about a central axis to pivot the vanes. The adjustment ring includes apertures that are each associated with and have received therein the outer portion of one of the vane levers. The outer portion of each of the vane levers includes an outer surface that is non-parallel with the central axis.
