Holder for an exhaust system of an internal combustion engine and method of making same

Abstract

A holder for an exhaust system of an internal combustion engine includes a holder body having a holder base and a holder wall extending from the holder base, and a holder pin. The holder pin extends from an outer face of the holder wall wherein, in the holder pin, a pin recess is formed in at least one peripheral region.

1 . A holder for an exhaust system of an internal combustion engine, the holder comprising:
 a holder body having a holder base and a holder wall extending from said holder base;   a holder pin extending from an outer face of said holder wall; and,   said holder pin having a pin recess being formed in at least one peripheral region thereof.   
     
     
         2 . The holder of  claim 1 , wherein at least one of the following applies:
 i) said holder base is formed so as to be plate-shaped; and,   ii) a fastening member reach-through opening is provided in said holder base; and,   iii) an anti-rotation protrusion extending in an opposite direction to an extension direction of said holder wall with respect to said holder base is provided on said holder base.   
     
     
         3 . The holder of  claim 1 , wherein at least one of the following applies:
 i) said holder wall extends at least in some regions along an outer peripheral region of the holder base; and,   ii) said holder wall is formed in an annular manner substantially without interruptions; and,   iii) said holder wall has a varying wall height starting from said holder base.   
     
     
         4 . The holder of  claim 3 , wherein said holder pin is provided on said holder wall in a region thereof having a maximum wall height. 
     
     
         5 . The holder of  claim 1 , wherein at least one reinforcing protrusion adjoining said holder base is provided on an inner face of said holder wall. 
     
     
         6 . The holder of  claim 5 , wherein two of said reinforcing protrusions arranged at a distance from one another are provided on said inner face of said holder wall; and, wherein at least one of the following applies:
 i) said holder pin adjoins said outer face of said holder wall between said two reinforcing protrusions; and,   ii) at least one of said two reinforcing protrusions adjoins said holder wall in an overlapping manner.   
     
     
         7 . The holder of  claim 5 , wherein at least one of the following applies:
 i) at least one of said two reinforcing protrusions is in the form of a rib; and,   b) at least one of said two reinforcing protrusions transitions into a wall region of said holder wall having a greater wall thickness which decreases in a direction away from said one reinforcing protrusion.   
     
     
         8 . The holder of  claim 1 , wherein said pin recess in said holder pin is formed at least in a first end region of said holder pin adjoining said holder wall. 
     
     
         9 . The holder of  claim 1 , wherein said holder pin defines a pin longitudinal axis and extends in a direction of said pin longitudinal axis; and, said pin recess is formed in said holder pin extending in the direction of said pin longitudinal axis so as to be open radially to the outside. 
     
     
         10 . The holder of  claim 1 , wherein said holder pin has a second end region remote from said holder wall; and, said holder pin has a pin head protruding with respect to an outer dimension of said holder pin at said second end region; and, said pin recess extends up to said pin head. 
     
     
         11 . The holder of  claim 1 , wherein said pin recess has a recess depth that is at least 30% of a cross-sectional dimension of said holder pin in a recess depth direction. 
     
     
         12 . The holder of  claim 1 , wherein said pin recess has a recess depth that is at least 50% of a cross-sectional dimension of said holder pin in a recess depth direction. 
     
     
         13 . The holder of  claim 1 , wherein said holder body is formed integrally with the holder pin as a die-cast part. 
     
     
         14 . The holder of  claim 1 , wherein said holder body is formed integrally with the holder pin as a die-cast part made from aluminum. 
     
     
         15 . A method for making a holder for an exhaust system of an internal combustion engine, the holder including: a holder body having a holder base and a holder wall extending from the holder base; a holder pin extending from an outer face of the holder wall; and, the holder pin having a pin recess being formed in at least one peripheral region thereof; the method comprising:
 making the holder body integrally as a die-cast part.   
     
     
         16 . The method of  claim 15 , wherein the die-cast part is made integrally from aluminum.
