Car body part

Abstract

A car body part, in particular a car body part of a rail vehicle, includes an extruded part with at least one fastening portion which is suitable for fastening an item of equipment, and extends in the extrusion direction of the extruded part. The extruded part is locally weakened by mechanical reworking and the fastening portion is flexible as a result of local weakening and forms a flexible fastening portion. An assembly having the car body part and an item of equipment and a method for producing the assembly are also provided.

         18 . The car body part according to  claim 17 , wherein said at least one flexible fastening portion is disposed above said at least one locally weakened location. 
     
     
         19 . The car body part according to  claim 16 , wherein:
 said extruded part includes a fastening rail being weakened locally or removed at least at two locations disposed one behind another in said extrusion direction; and   said at least one flexible fastening portion is formed by a portion of said fastening rail lying between said two locations in said extrusion direction.   
     
     
         20 . The car body part according to  claim 17 , wherein said fastening rail of said extruded part has a cross section with a closed contour being open in the vicinity of said at least one locally weakened location. 
     
     
         21 . The car body part according to  claim 19 , wherein said fastening rail of said extruded part has a cross section with a closed contour being open in the vicinity of said locally weakened locations. 
     
     
         22 . The car body part according to  claim 17 , wherein said fastening rail of said extruded part has a cross section with an open contour. 
     
     
         23 . The car body part according to  claim 19 , wherein said fastening rail of said extruded part has a cross section with an open contour. 
     
     
         24 . An assembly, comprising:
 a car body part according to  claim 16 ; and   an item of equipment mounted on said at least one mechanically reworked and locally mechanically weakened flexible fastening portion of said car body part.   
     
     
         25 . The assembly according to  claim 24 , wherein said item of equipment is screw-connected on said at least one flexible fastening portion and said at least one flexible fastening portion is deformed locally as a result of said screw connection. 
     
     
         26 . The assembly according to  claim 24 , wherein:
 said car body part forms a roof or a roof part of a rail vehicle car body; and   said item of equipment is mounted on said roof or roof part.   
     
     
         27 . The assembly according to  claim 26 , wherein:
 the assembly forms a rail vehicle;   said item of equipment includes a converter, a transformer, an air-conditioning component or a current collector or is formed by a component; and   said item of equipment is mounted on said roof of said rail vehicle car body part.   
     
     
         28 . A method for producing an assembly having a car body part formed by an extruded part and an item of equipment, the method comprising the following steps:
 mechanically weakening the extruded part locally by mechanical reworking and forming at least one flexible fastening portion for fastening the item of equipment; and   mounting the item of equipment on or at the at least one flexible fastening portion.   
     
     
         29 . The method according to  claim 28 , which further comprises carrying out the mounting step by screw-connecting the item of equipment on or at the at least one flexible fastening portion. 
     
     
         30 . The method according to  claim 28 , which further comprises removing material of the extruded part to carry out the step of weakening the extruded part locally by mechanical reworking. 
     
     
         31 . The method according to  claim 30 , which further comprises carrying out the step of removing the material of the extruded part by milling or boring. 
     
     
         32 . The method according to  claim 29 , which further comprises pressing a fastening surface of the item of equipment flatly onto a fastening surface of the at least one flexible fastening portion of the extruded part as a result of the screw-connecting of the item of equipment at the at least one flexible fastening portion. 
     
     
         33 . The method according to  claim 32 , which further comprises deforming a region about the fastening surface of the at least one flexible fastening portion as a result of the screw-connecting of the item of equipment on the at least one flexible fastening portion of the extruded part. 
     
     
         34 . The method according to  claim 28 , which further comprises effecting the local weakening of the extruded part by locally opening a contour having a closed cross section of a fastening rail of the extruded part. 
     
     
         35 . The method according to  claim 28 , which further comprises:
 locally weakening or removing a fastening rail of the extruded part at least at two locations disposed one behind another in an extrusion direction; and   forming the at least one flexible fastening portion by a portion of the fastening rail disposed between the two locations in the extrusion direction.
