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

Control ring for variable turbine geometry

The present disclosure relates to an exhaust gas turbocharger for a motor vehicle. The turbocharger includes a turbine housing having a first area in which exhaust is carried to a turbine wheel and in which the turbine wheel is essentially situated and having a second area connected axially to the first area, such that the first area and the second area are essentially separated from one another by a separating element. It is provided that for thermal insulation, the separating element is made of a material having a low thermal conduction and/or thermal capacity.
