Abstract
The invention relates to a turbine housing (2) for an exhaust gas turbocharger. The turbine housing (2) comprises an outer housing (3) and an inner housing (4) as well as a bearing flange (5). The outer housing (3) is joined to the bearing flange (5). The inner housing (4) comprises a first shell component (7) and a second shell component (8), wherein said first shell component and said second shell component are made of different cast steel materials and are placed side by side in a transverse plane (QE), which is oriented transversely to the longitudinal axis (LA) of the turbine housing (2), and are joined to each other. The bearing flange (5) is a one-piece part, made of uniform material, of the first shell component (7).
Claims7
A turbine housing, which is designed for an exhaust gas turbocharger and which comprises an outer housing consisting of a high nickel content steel alloy and an inner housing consisting of lower nickel content steel alloy as well as a bearing flange, wherein the outer housing is joined to the bearing flange, the inner housing comprises a first shell component and a second shell component, said first shell component and said second shell component being joined to each other;
- and the two shell components being made of different cast nickel steel alloys;
- wherein the bearing flange is a unitary part, made of the same cast nickel steel alloy material as the first shell component;
- wherein the two shell components are placed side by side in a transverse plane (QE), which is oriented transverse to the longitudinal axis (LA) of the turbine housing, and are connected to each other by means of a circumferential joint seam on the outer periphery of the inner housing.
