摘要

The turbocharger has a turbine wheel (13) as an integral part of a shaft. A compressor wheel (12) is connected with the shaft by a circular wedge connection, where the wheels (13, 12) are arranged in turbine and compressor casings. A bearing housing is arranged between the housings, where the wheel (13) and the shaft are designed as a single piece and manufactured from a high temperature-firm material e.g. titanium aluminide material.
