Adjustment ring for a charger, in particular an exhaust gas turbocharger of a motor vehicle

摘要

The device has a variable turbine-/compressor geometry (1) including adjustable guide vanes (5, 5'), which are engaged with an adjusting ring (2) over associated adjusting levers (3, 3') and are adjustable together by the levers. The adjusting ring is reinforced in engaging areas (7, 7') that are in contact with the respective adjusting levers. Reinforcement of the engaging areas is designed as bulge and/or as upstand and/or as a profile on upper- and/or lower sides of the adjusting ring. The reinforcement is designed as a separate component fixable at the adjusting ring. An independent claim is also included for a method for production of an adjusting ring usable in a loading device.
