Abstract
A vane pack assembly () for a variable geometry turbocharger () including a an upper vane ring () and a lower vane ring () and a plurality of single-axle, self-centering adjustable guide vanes () disposed in a turbine housing (). The plurality of guide vanes () include a post () having a vane () formed integrally therewith. Each post () includes a convex self-centering pivot feature () at one end adapted to seat in a complementary shaped concave self-centering pivot recess () of the lower vane ring. The vanes () are positioned between the upper and lower vane rings () and pivot to control exhaust flow to a turbine wheel. The self-centering pivot features compensate for movement or deformation of the turbine housing () and vane rings () due to the effects of differential thermal expansion.
