Rail vehicle

Abstract

A rail vehicle has improved rigidity against vertical bending vibration while avoiding an increase in mass of the rail vehicle and interference with infrastructure equipment. The rail vehicle includes a roof body constituting an upper surface; a side body constituting a side surface; an end body constituting an end surface in a longitudinal direction of the side body; an underframe constituting a lower surface; and a bogie supporting the underframe, in which the side body includes a plurality of openings and a pier between the openings, and a reinforcing body is arranged on a vehicle interior surface of the pier between one opening situated above the bogie and an other opening adjacent to the one opening and situated near a center in a longitudinal direction of the rail vehicle so as to extend from an upper corner of the one opening toward a lower corner of the other opening.

1 . A rail vehicle comprising: a roof body constituting an upper surface; a side body constituting a side surface; an end body constituting an end surface in a longitudinal direction of the side body; an underframe constituting a lower surface; and a bogie supporting the underframe,
 wherein the side body includes a plurality of openings and a pier between the openings, and   a reinforcing body is arranged on a vehicle interior surface of the pier between one opening situated above the bogie and an other opening adjacent to the one opening and situated near a center in a longitudinal direction of the rail vehicle so as to extend from an upper corner of the one opening toward a lower corner of the other opening.   
     
     
         2 . The rail vehicle according to  claim 1 , wherein
 the reinforcing body is arranged in the pier so as to extend from a lower corner of the one opening toward an upper corner of the other opening.   
     
     
         3 . The rail vehicle according to  claim 1 , wherein
 the reinforcing body is made of a fiber resin, and   an extension direction of the fiber is along an extension direction of the reinforcing body.   
     
     
         4 . The rail vehicle according to  claim 1 , wherein
 the opening is a rectangular window.   
     
     
         5 . The rail vehicle according to  claim 1 , wherein
 the opening is a rectangular doorway.   
     
     
         6 . The rail vehicle according to  claim 1 , wherein
 as viewed in a width direction of the rail vehicle, the opening adjacent to the pier provided with the reinforcing body overlaps a center line of the bogie in a longitudinal direction of the rail vehicle.
