    Description: [0001] The invention relates to a turbocharger according to the preamble of claim 1. Furthermore, the invention relates to a thrust bearing for such a turbocharger.
    The basic structure of a turbocharger is well known. For example, a turbocharger has a turbine for the expansion of exhaust gas and a compressor for compressing the charge air. The turbine of a turbocharger has a blasted turbine rotor and a turbine housing. The compressor has a blended compressor rotor and a compressor housing. The compressor rotor of the compressor can be driven starting from the turbine rotor of the turbine and for this purpose coupled to the turbine rotor via a shaft having a thrust bearing. The thrust bearing comprises a thrust washer, which is made in the prior art of bronze or other metallic material.
    Proceeding from this, the present invention seeks to provide a novel turbocharger and a novel thrust bearing for a turbocharger.
    This object is achieved by a turbocharger according to claim 1. According to the invention, the thrust washer is made of a fiber composite material. In the turbocharger according to the invention, the axial bearing disk is manufactured from a fiber composite material. As a result, the life of the thrust bearing of the thrust bearing can be increased. Maintenance intervals of the turbocharger can be extended.
    According to an advantageous embodiment of the invention, the thrust washer is made of a reinforced with carbon fibers, ceramic material. Preferably, the thrust washer is made of carbon fiber reinforced silicon carbide material. The use of these materials for the thrust washer is particularly preferred because they are particularly resistant to wear.
    According to a further advantageous embodiment of the invention oil guide grooves are introduced into the thrust washer. Cooling oil and / or lubricating oil can be guided simply and reliably in the region of the axial bearing via the oil guide grooves.
    The inventive thrust washer for a turbocharger is defined in claim 5.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawing. Showing:
    1 shows a detail of a turbocharger in a perspective view;
    2 shows a detail of the turbocharger of FIG. 1 in an exploded view.
    The present invention relates to a turbocharger of an internal combustion engine, in particular a turbocharger of a marine diesel engine.
    Fig. 1 shows a section of a turbocharger 10, wherein the turbocharger 10 comprises a turbine 11 for the expansion of exhaust gas and a compressor 12 for the compression of charge air.
    For relaxing exhaust gas of the turbine 11 via an exhaust inlet 13 can be fed. Relaxed exhaust gas can be removed from the turbine 11 via an exhaust gas outlet 14.
    To be compressed charge air is the compressor 12 via an air inlet 15 can be fed. Compressed charge air can be discharged from the compressor 12 via a charge air outlet 16.
    The air inlet 15 and the charge air outlet 16 are provided by a stator-side compressor housing 17 of the compressor 12.
    The exhaust gas inlet 13 and the exhaust gas outlet 14 are provided by a turbine-side stator housing 18 of the turbine 11.
    The turbine 11 comprises, in addition to the stator-side turbine housing 18, a blown-on turbine rotor 19. The turbine rotor 19 is rotatably mounted in the turbine housing 18.
    The compressor 12 has in addition to the stator-side compressor housing 17 via a beschaufeiten compressor rotor 20 which is rotatably mounted in the compressor housing 17.
    The compressor rotor 20 is drivable starting from the turbine rotor 19, wherein the turbine rotor 19 and the compressor rotor 20 are coupled via a shaft 21 to drive the compressor rotor 20, starting from the turbine rotor 19. For supporting the shaft 21, a compressor-side bearing bush 22 and a turbine-side bearing bush 23 are provided, which are accommodated in a bearing housing 24.
    The bearing for the shaft 21, which couples the turbine rotor 19 with the compressor rotor 20, has a thrust bearing 25. The thrust bearing 25 cooperates with an abutment 26, wherein between the thrust bearing 25 and the abutment 26 on the one hand a thrust washer 27 and on the other hand, a support ring 28 is positioned.
