ABSTRACT:
In a turbocharger (1), comprising a turbine (2) and a compressor (3) connected to the turbine (2), the turbine (2) contains a turbine wheel (4) and the compressor (3) contains a compressor wheel (7) which are connected to one another by means of a shaft (10) and are arranged in a housing (5, 9, 16). During operation, if the compressor wheel (7) separates from the shaft (10), an axial force acts on the turbine wheel (4) and the shaft (10) connected thereto.A means (22, 25) for axially locking the shaft and the turbine wheel connected thereto in the housing (5, 9, 16) is arranged on the shaft (10) connected to the turbine wheel (4).
