Heat shield and turbocharger having a heat shield

Abstract

A heat shield, in particular for a turbocharger, has a disk or a pot shape which is stepped once or multiple times. The disc or pot shape has an outer edge, and the outer edge is provided with at least one opening section. The opening section forms a web section with the outer edge, said web section being bent outward in order to form a spring arm. The web section is either designed as closed or as open at one point.

         21 . The heat shield according to  claim 18 , wherein said web section is one, two, three, four, or more web sections arranged in a track on said outer rim. 
     
     
         22 . The heat shield according to  claim 18 , wherein said disc or pot shape has at least one or more additional tracks, said tracks each having one, two, three, four, or more web sections. 
     
     
         23 . The heat shield according to  claim 22 , wherein said tracks each has a common number or a different number of web sections. 
     
     
         24 . The heat shield according to  claim 18 , wherein said web sections of one track or of a plurality of tracks are substantially identical in terms of shape, size, and/or arrangement. 
     
     
         25 . The heat shield according to  claim 18 , wherein said web sections of one track or of a plurality of tracks are substantially different in terms of shape, size, and/or arrangement. 
     
     
         26 . The heat shield according to  claim 18 , wherein at least one or more web sections are open at one end, and the respective said segment of said web section is bent outwards. 
     
     
         27 . The heat shield according to  claim 18 , wherein at least one or more web sections are open at a center thereof, and the respective said segment of said web section is bent outwards. 
     
     
         28 . The heat shield according to  claim 18 , wherein said web sections of at least two or more tracks are arranged mutually offset or partly offset from one another. 
     
     
         29 . The heat shield according to  claim 18 , wherein said web sections of at least two or more tracks are substantially in line with one another. 
     
     
         30 . The heat shield according to  claim 18 , wherein the respective said web section or a segment of said web section is bent outwards by a predetermined amount, setting a predetermined spring displacement of said spring arm. 
     
     
         31 . The heat shield according to  claim 30 , wherein said web sections or said segments of said web sections are bent outwards by a common amount. 
     
     
         32 . The heat shield according to  claim 30 , wherein said web sections or said segments of said web sections are bent outwards by mutually different amounts. 
     
     
         33 . The heat shield according to  claim 18 , wherein said outer rim of said disc is curved outwardly with a uniform curvature. 
     
     
         34 . The heat shield according to  claim 18 , wherein said outer rim of said disc is curved outwardly with a stepped contour having one, two, or more steps. 
     
     
         35 . The heat shield according to  claim 18 , formed of a heat-resistant or high temperature-resistant material configured according to an intended use thereof. 
     
     
         36 . The heat shield according to  claim 18 , formed of a heat-resistant or high temperature-resistant metal or metal alloy. 
     
     
         37 . The heat shield according to  claim 18 , formed of a turned part, or of a bent metal part, or of a bent sheet metal part. 
     
     
         38 . The heat shield according to  claim 18 , wherein said web section or said segment of said web section is bent outwards substantially tangentially. 
     
     
         39 . The heat shield according to  claim 18 , formed with a through-hole for fixing or centering the heat shield on a turbocharger.
