Abstract

A turbine housing for a turbocharger has a plurality of interconnected housing parts. A central, one-piece contoured component that is constructed as a cast component or a forged component is provided on that side of a spiral channel which faces away from a bearing housing attachment flange in the turbine housing. The contoured component has a wall region of the spiral channel, a boundary wall of an exhaust gas inlet gap and a sealing contour region. The contoured component is connected to its adjacent housing parts, which are at least partly constructed as sheet metal molded parts, so as to form the turbine housing.
