SECURING ELEMENT AND EXHAUST GAS TURBOCHARGER HAVING VARIABLE TURBINE GEOMETRY

摘要

The invention relates to a securing element (1) comprising a head section (2), a shank (3), the cross-section of said shank changing in the axial direction such that, by taking into account a qualitative and/or quantitative predetermined bending torque profile in the shank, the cross-section has an essentially uniform bending stress profile in the shank in relation to a securing element with a constant shank cross-section. The invention also relates to an exhaust gas turbocharger (11) having variable turbine geometry in which a VTG-guide vane arrangement (15) comprising at least one securing element (1) of said type is secured to a housing component (12) of the exhaust gas turbocharger.
