Abstract
A variable geometry turbocharger assembly employing the present invention includes a center housing, a compressor housing attached to one side of the center housing, and a turbine housing attached to another side of the center housing. A plurality of movable vanes is disposed within the turbine housing, and a unison ring is rotatably disposed within the turbine housing to move the vanes in unison. The turbocharger includes a unison ring assembly of this invention that includes an insert that is separate from and attached to the center housing. The support has one or more surfaces to carry the unison ring, and the unison ring is rotatably positioned on the support. The support further provides a space that isolates the unison ring from making contact with contacting the center housing. A heat shroud optionally extends radially inwardly along the center housing and is retained into position by the support.
