Abstract
The invention relates to a variable turbine geometry () of an exhaust gas turbocharger () of a motor vehicle, with a fixed guide blade ring () and an axially moveable control blade ring (), wherein an axial relative position of guide blades () of the guide blade ring () to control blades () of the control blade ring () defines the size of inflow cross sections to a turbine wheel () of the exhaust gas turbocharger (), and wherein the guide blades () and the control blades () extend in directions opposite to each other as far as to their respective free ends () and the control blades () are arranged on a cross carrier of the control blade ring (), which as a function of the axial relative position opens, partially opens or closes additional inflow paths () for the enlargement or the reduction of the inflow cross sections. Furthermore, an exhaust gas turbocharger () with such a variable turbine geometry () as well as a method for the control of the inflow of an exhaust gas turbine with such a variable turbine geometry is proposed.
