Charging device i.e. exhaust gas turbocharger, for motor vehicle, has turbine or compressor geometry comprising guide vanes and mounted in axial direction, where each vane has blade, pin and rim connected with one another as single-piece

摘要

The device has a variable turbine or compressor geometry (1) comprising guide vanes (3) supported at a vane bearing ring (2) in a rotatable manner and an adjusting ring (4) for adjusting the vanes. Each vane has a guide vane blade (5), a vane bearing pin and a toothed rim (8) that are connected with one another as a single-piece. The geometry is designed in such a manner that the geometry is assembled and mounted in an axial direction (14). The vanes and the adjusting ring are manufactured in a metal inject moulding process from ceramics, and the bearing ring is designed as rotating part. An independent claim is also included for a method for mounting a charging device.
