Railway Vehicle

Abstract

The invention provides a car body of a railway vehicle capable of absorbing the energy caused when collision occurs to the end of the car body. The present invention comprises a strength member 15 disposed along the circumferential direction of the car body on the end of the car body, a strength member 16 disposed along the circumferential direction at a position rearward from the member 15 , rib members 17 disposed along the longitudinal direction of the car body and connecting the two strength members, and an outer panel 18 covering the same. The longitudinal direction of the rib member 17 corresponds to the longitudinal direction of the car body. The rib member 17 is composed of two flanges 17 c , 17 d and a web 17 b connecting the two flanges, and the side having the web 17 b is welded to the outer panel 18 via fillet welding. A notch 21 opened to the edge of the flange is formed on the flange at the center of the longitudinal direction of the rib member 17 . When collision load is applied, the notch 21 is valley-folded, by which the rib member is bent toward the direction opposite from the side to which the outer panel 18 is attached, so that the collision load can be absorbed sufficiently since the outer panel 18 will not interfere with the buckling of the rib member 17.

1 . A railway vehicle having at an end of an intermediate car or at an end of a car connected to the intermediate car of a railway car formation the following:
 two strength members disposed along the perpendicular direction of side walls of a crew cabin and along a roof at the end of the car, one of the strength members disposed at the leading end of the car body in the longitudinal direction thereof and the other member disposed rearward than the first member in the longitudinal direction of the car body; wherein   the end of the car body is composed of the front and rear strength members of the car body, rib members welded to the strength members, and an outer panel covering the rib members and the two strength members;   the longitudinal direction of the rib member is disposed along the longitudinal direction of the car body;   the rib member is composed of two flanges and a web connecting the two flanges;   the web of the rib member is welded via fillet welding to the outer panel;   the flanges are each provided with a notch that opens to the edge of the flanges at the middle in the longitudinal direction of the rib member; and   the web has a hole formed between the notches and the longitudinal end of the rib member.   
   
   
       2 . A railway vehicle having at an end of an intermediate car or at an end of a car connected to the intermediate car of a railway car formation the following:
 two strength members disposed along the perpendicular direction of side walls of a crew cabin and along a roof at the end of the car, one of the strength members disposed at the leading end of the car body in the longitudinal direction thereof and the other member disposed rearward than the first member in the longitudinal direction of the car body; wherein   the end of the car body is composed of the front and rear strength members of the car body, rib members welded to the strength members, and an outer panel covering the rib members and the two strength members;   the longitudinal direction of the rib member is disposed along the longitudinal direction of the car body;   the rib member is composed of two flanges and a web connecting the two flanges;   the ends of the flanges are welded via fillet welding to the outer panel;   the flanges and the web are provided with a notch formed so that the center of the notch corresponds to a bent portion between the web and the flange; and   the web has a hole formed between the notches and the longitudinal end of the rib member.   
   
   
       3 . A railway vehicle having at an end of an intermediate car or at an end of a car connected to the intermediate car of a railway car formation the following:
 two strength members disposed along the perpendicular direction of side walls of a crew cabin and along a roof at the end of the car, one of the strength members disposed at the leading end of the car body in the longitudinal direction thereof and the other member disposed rearward than the first member in the longitudinal direction of the car body; wherein   the end of the car body is composed of the front and rear strength members of the car body, a plurality of rib members welded to the strength members, and an outer panel covering the rib member and the two strength members;   the longitudinal direction of the rib member is disposed along the longitudinal direction of the car body;   the rib member is composed of two flanges and a web connecting the two flanges; and   one end of the rib member in the longitudinal direction of the car body is branched into a Y-shape, whereas the other end thereof is not branched.
