Controlled-route vehicle, in particular train, with improved air intake

Abstract

A controlled-route vehicle, in particular a train, includes at least one air passage disposed in a wall of the controlled-route vehicle. The air passage has an inlet opening, disposed in an outer side of the wall, for letting air into the air passage, an outlet opening, disposed in an inner side of the wall, through which the air can be let out into an interior of the controlled-route vehicle, and a section which tapers in the direction of the outlet opening and is formed by an inner wall side of the wall. As a result, improved transport of the air into the interior of the controlled-route vehicle can be achieved in a structurally simple and inexpensive manner.

         23 . The controlled-route vehicle according to  claim 20 , which further comprises a transverse direction, said inner wall side having a plurality of connected lamellas at least in vicinity of said section, and each lamella of said plurality of lamellas having a longitudinal side and an elongate shape in said transverse direction and being connected on said longitudinal side of said lamella to a further lamella of said plurality of lamellas. 
     
     
         24 . The controlled-route vehicle according to  claim 20 , wherein said curved section of said inner wall side has a uniform curvature. 
     
     
         25 . The controlled-route vehicle according to  claim 20 , wherein said section of said inner wall side has an adjustable curvature. 
     
     
         26 . The controlled-route vehicle according to  claim 17 , which further comprises a protective grille disposed inside said outlet opening of said at least one air passage. 
     
     
         27 . The controlled-route vehicle according to  claim 26 , wherein said protective grille has a flat shape. 
     
     
         28 . The controlled-route vehicle according to  claim 26 , which further comprises a longitudinal direction, said protective grille having a substantially inwardly-curved shape in said longitudinal direction. 
     
     
         29 . The controlled-route vehicle according to  claim 26 , wherein said protective grille has an adjustable curvature.
