Hollow-chamber profile floor for a rail vehicle

Abstract

A hollow-chamber profile floor for a rail vehicle includes an upper floor and a lower floor which are connected to one another by struts and/or posts extending between the upper floor and lower floor. The spacing between the upper floor and the lower floor corresponds to a first value in a first region and the spacing between the upper floor and lower floor corresponds to a second value in a second region, and the first spacing value is less than the second spacing value.

1 - 10 . (canceled) 
     
     
         11 . A hollow-chamber profile floor for a rail vehicle, the hollow-chamber profile floor comprising:
 an upper flange and a lower flange defining a spacing therebetween;   at least one of struts or posts extending between said upper flange and said lower flange and interconnecting said upper flange and said lower flange;   a first region and a second region;   said spacing between said upper flange and said lower flange in said first region corresponding to a value A, said spacing between said upper flange and said lower flange in said second region corresponding to a value B, and A being less than B.   
     
     
         12 . The hollow-chamber profile floor according to  claim 11 , wherein said first region includes two partial regions and said second region is disposed between said partial regions. 
     
     
         13 . The hollow-chamber profile floor according to  claim 11 , wherein said first region is greater than said second region, relative to a width of the rail vehicle. 
     
     
         14 . The hollow-chamber profile floor according to  claim 12 , wherein said partial regions are each smaller than said second region. 
     
     
         15 . The hollow-chamber profile floor according to  claim 12 , which further comprises transition regions each disposed between a respective one of said partial regions and said second region, said spacing between said upper flange and said lower flange in said transition regions corresponding to a value C, and A<C<B. 
     
     
         16 . The hollow-chamber profile floor according to  claim 15 , which further comprises floor supports connecting the floor to longitudinal carriers of a rail vehicle shell. 
     
     
         17 . The hollow-chamber profile floor according to  claim 16 , wherein said spacing between said upper flange and said lower flange in a region of said floor supports corresponds to said spacing B in said second region. 
     
     
         18 . The hollow-chamber profile floor according to  claim 16 , which further comprises other transition regions each adjoining a region of a respective one of said floor supports, said spacing between said upper flange and said lower flange in said other transition regions corresponding to said spacing C in said transition region. 
     
     
         19 . The hollow-chamber profile floor according to  claim 11 , which further comprises securing devices for under floor securing of cable ducts. 
     
     
         20 . A rail vehicle, comprising:
 a bogie; and   a hollow-chamber profile floor according to  claim 11  disposed at least in a region of said bogie.
