Axial bearing arrangement for a shaft of a turbocharger

Abstract

A turbocharger has a turbocharger housing. At least one section of the turbocharger housing is divided in the longitudinal direction into at least two housing halves. A shaft is supported in the turbocharger housing and at least one axial bearing arrangement is provided for supporting the shaft in the axial direction.

1 - 10 . (canceled) 
     
     
         11 . A turbocharger ( 10 ), comprising:
 a turbocharger housing, said turbocharger housing having at least one section divided in a longitudinal direction to form at least two housing halves;   a shaft mounted in said turbocharger housing; and   at least one axial bearing arrangement disposed to support said shaft in an axial direction.   
     
     
         12 . The turbocharger according to  claim 11 , wherein said axial bearing arrangement comprises at least one axial bearing, said axial bearing being disposed on said shaft, on a bearing core, or on a bearing collar on said shaft. 
     
     
         13 . The turbocharger according to  claim 12 , wherein said turbocharger housing is formed with a boundary portion on one side or on both sides of said axial bearing, said boundary portion being configured integrally with said turbocharger housing or being a separate part fastened to said turbocharger housing. 
     
     
         14 . The turbocharger according to  claim 12 , wherein said axial bearing has a circumference with at least one projection or bracket element for fastening said axial bearing to said turbocharger housing, said axial bearing being fastened by said projection or bracket element to said turbocharger housing. 
     
     
         15 . The turbocharger according to  claim 14 , wherein said axial bearing is fastened by said projection or bracket element to said turbocharger housing by way of screw fixing and/or pinning. 
     
     
         16 . The turbocharger according to  claim 11 , wherein said axial bearing is fastened to an insert sleeve, to a bearing collar, to a bearing core and/or to said turbocharger housing. 
     
     
         17 . The turbocharger according to  claim 16 , wherein said axial bearing is fastened by way of screw fixing and/or pinning. 
     
     
         18 . The turbocharger according to  claim 11 , wherein said axial bearing is disposed in a receptacle of said turbocharger housing, and wherein at least one spring element is disposed to brace said axial bearing in said receptacle. 
     
     
         19 . The turbocharger according to  claim 18 , wherein said receptacle is a recess or a hollow in said turbocharger housing. 
     
     
         20 . The turbocharger according to  claim 11 , wherein said axial bearing is disposed in a receptacle of said turbocharger housing. 
     
     
         21 . The turbocharger according to  claim 20 , wherein said receptacle has a first receptacle section and said first receptacle section forms with said axial bearing a transition fit or a clearance fit. 
     
     
         22 . The turbocharger according to  claim 21 , wherein said receptacle has a second receptacle section, and wherein at least one disk element and/or a spring element is disposed in said second receptacle section in order to prevent unwanted axial movement of said axial bearing. 
     
     
         23 . The turbocharger according to  claim 22 , wherein said at least one disk element is an oil barrier ring. 
     
     
         24 . The turbocharger according to  claim 22 , wherein said receptacle is formed as a stepped recess having one step forming said first receptacle section and a second step forming said second receptacle section. 
     
     
         25 . The turbocharger according to  claim 11 , wherein said axial bearing is selected from the group consisting of an axial bearing disk, an axial sliding bearing, an axial magnetic bearing, and an axial rolling bearing.
