Adjusting ring for a charging device, more preferably for an exhaust gas turbocharger of a motor vehicle

摘要

The invention relates to a charging device, more preferably an exhaust gas turbocharger for a motor vehicle with a variable turbine/compressor geometry (1) with a plurality of adjustable guide blades, which are each engaged with an adjusting ring (2) via a corresponding lever (3, 3′) and which are preferentially jointly adjustable through said adjusting ring. Through a reinforcement (10) of a plurality of engagement regions (7, 7′) of the adjusting ring (2) which are in contact with an adjusting lever (3, 3′) each, higher force transmission from the adjusting ring (2) to the adjusting levers (3, 3′) is made possible without disadvantageous plastic deformation of the adjusting ring (2) or of the adjusting levers (3, 3′).
