Abstract:
The invention relates to a variable turbine geometry (12) of a supercharging device, in particular an exhaust gas turbocharger for an internal combustion engine. The variable turbine geometry (12) comprises guide vanes (30) that are assigned to the circumference of a turbine rotor and are operated by means of a control ring (22) that is accommodated on journals (16) of the guide vanes (30). The control ring (22) is locked on these supporting journals (16) of the guide vanes (30).
