Travel way for a track-guided vehicle

Abstract

The invention relates to a travel way for a track-guided vehicle, especially a magnetic levitation railway, comprising a carrier (1) and at least one add-on piece (3) (functional element) which is fixed to the carrier(1) and is used to guide the vehicle. The inventive travel way is characterised in that the add-on piece (3) is connected to the carrier (1) in a frictionally engaged manner and means are provided, in the form of a redundancy system, for an auxiliary non-positive connection.

         13 . A travelway for a track guided vehicle, said travelway comprising: 
 a carrier;    at least one attachment bound by a frictional connection to said carrier, said at least one attachment configured to provide guidance to the track guided vehicle; and    at least one first shape-fit auxiliary component operably disposed between said carrier and said at least one attachment, said at least one first shape-fit auxiliary component serves as a redundancy system to retain said at least one attachment to said carrier upon failure of said frictional connection, whereby said redundancy system reveals said failure in such a manner that a vehicle traveling over the travelway is capable of detecting a displacement of said at least one attachment.    
     
     
         14 . A travelway as in  claim 13 , wherein the travelway is for a magnetically levitated railway.  
     
     
         15 . A travelway as in  claim 13 , wherein said carrier includes a console firmly bound to said carrier, said at least one attachment connected to said console by said frictional connection and said redundancy system.  
     
     
         16 . A travelway as in  claim 13 , wherein said at least one first shape-fit auxiliary component comprises a bolt fastened to said carrier, at least one portion of said bolt resting within a concentric opening formed in said at least one attachment with said concentric opening being of a greater diameter than said at least one portion of said bolt resting within said concentric opening so that said at least one portion of said bolt and said concentric opening are axially aligned when said frictional connection binds said at least one attachment to said carrier.  
     
     
         17 . A travelway as in  claim 16 , wherein a cross-section of said at least one portion of said bolt and a cross section of said concentric opening are circular and exhibit a difference in diameters.  
     
     
         18 . A travelway as in  claim 17 , wherein said difference in diameters comprises 4 mm.  
     
     
         19 . A travelway as in  claim 17 , wherein said cross-section of said at least one portion of said bolt and said cross section of said concentric opening are chosen based on the desired displacement of said at least attachment.  
     
     
         20 . A travelway as in  claim 13 , wherein said at least one first shape-fit auxiliary component comprises a bolt fastened to said at least one attachment, at least one portion of said bolt resting within a concentric opening formed in said carrier with said concentric opening being of a greater diameter than said at least one portion of said bolt and said concentric opening are axially aligned when said frictional connection binds said at least one attachment to said carrier.  
     
     
         21 . A travelway as in  claim 20 , wherein a cross-section of said at least one portion of said bolt and a cross-section of said concentric opening formed in said carrier are circular and exhibit a difference in diameters.  
     
     
         22 . A travelway as in  claim 21 , wherein said difference in diameters comprises 4 mm.  
     
     
         23 . A travelway as in  claim 21 , wherein said cross-section of said at least one portion of said bolt and said cross section of said concentric opening found in said carrier are chosen based on the desired displacement of said at least one attachment.  
     
     
         24 . A travelway as in  claim 13 , wherein at least one second shape-fit auxiliary component is operably disposed between said carrier and said at least one attachment, said at least one second shape-fit auxiliary component serves as a second redundancy system to retain said at least one attachment to said carrier upon failure of said at least one first shape-fit auxiliary component connection, whereby said second redundancy system reveals said failure in such a manner that a vehicle traveling over the travelway is capable of detecting a further displacement of said at least one attachment.  
     
     
         25 . A travelway as in  claim 13 , wherein at least one second shape-fit auxiliary component are screws used in screw attachments, whereby at least one of said carrier or said at least one attachment forms screw borings that are larger in diameter than a diameter of screws used in said screw attachment.  
     
     
         26 . A travelway as in  claim 25 , wherein said screw borings and said screws have a difference in diameters of 6 mm.  
     
     
         27 . A travelway as in  claim 13 , wherein at least one first shape-fit auxiliary component is a projection disposed on said carrier, said projection configured to fit into a corresponding boring within said at least one attachment with a specified annular clearance.  
     
     
         28 . A travelway as in  claim 13 , wherein at least one first shape-fit auxiliary component is a projection disposed on said at least one attachment, said projection configured to fit into a corresponding boring within said carrier with a specified annular clearance.  
     
     
         29 . A travelway as in  claim 13 , wherein at least one of a carrier connection surface of said carrier or an attachment connection surface on said at least one attachment comprises a frictional surface structure.  
     
     
         30 . A travelway as in  claim 29 , wherein at least one of said carrier connection surface on said carrier or said attachment connection surface on said at least one attachment comprise a friction enhancing coating.  
     
     
         31 . A travelway as in  claim 13 , wherein said friction enhancing coating comprises a alkali-zinc-silicate base.
