ASSEMBLY STRUCTURE OF VARIABLE GEOMETRY TURBOCHARGER

摘要

A coupling structure of a variable capacity control turbocharger is provided to improve durability of turbocharger because a vane hub of a vane cartridge is directly anchored on a center housing. A coupling structure of a variable capacity control turbocharger comprises a hub cover(11) surrounding the outer edge of the vane hub(3) and is connected in a center housing(9), an anti-pivot protrusion(13) which protrudes toward the center housing of the vane hub, and a protrusion groove(15) which is placed in the center housing so that the anti-pivot protrusion is inserted.
