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).
Claims20
A variable turbine geometry supercharging device, comprising:
- a turbine rotor including a circumference;
- a control ring;
- a plurality of guide vanes, each including a guide vane journal configured on the circumference of the turbine rotor, wherein the plurality of guide vanes and guide vane journals are operable by means of the control ring, which is mounted on the guide vane journals, such that the guide vane journals extend through an opening in a surface of the control ring,
- wherein the control ring is supported by and locked on the guide vane journals by a bayonet closure configured on the guide vane journals.
A variable turbine geometry supercharging device, comprising:
- a turbine rotor including a circumference;
- only a single control ring;
- a plurality of guide vanes;
- a plurality of guide vane journals, each guide vane journal extending from a guide vane, wherein the plurality of guide vanes are configured on the circumference of the turbine rotor and are operable by means of the single control ring,
- wherein the control ring is radially supported on the guide vane journals and axially locked by a portion of the guide vane journals extending through an opening in a surface of the control ring.
