Embodiment Construction

[0026] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. Hereinafter, the same reference numerals are assigned to the same or corresponding elements throughout the drawings, and repeated descriptions will be omitted.

[0027] (first embodiment)

[0028] First, refer to Figure 1 to Figure 6 The railway vehicle 100 according to the first embodiment of the present invention will be described. figure 1 It is a perspective view of the railway vehicle 100 according to this embodiment, and is a view of a state where an end outer panel is removed. Such as figure 1 As shown, the railway vehicle 100 according to this embodiment has a basic structure of an underframe 10 having end beams 11 at ends in the vehicle longitudinal direction (vehicle longitudinal direction), side structures 20 , and roof structures 30 . Moreover, the railroad vehicle 100 is equipped with the side outer panel 21, the corner post 40, and the interme...

Abstract

A railcar (100) according to the present invention includes: an underframe (10) including an end beam (11) at its railcar-longitudinal-direction end portion; side bodyshells (20); a roof bodyshell (30); side outside plates (21) respectively arranged at both railcar-width-direction end portions of the railcar and constituting the side bodyshells (20); corner posts (40) extending from the end beam (11) toward the roof bodyshell (30); and intermediate coupling members (50) each configured to couple the side outside plate (21) and the corner post (40), the stiffness of the intermediate coupling member (50) in a railcar longitudinal direction being lower than the stiffness of the intermediate coupling member (50) in a vertical direction.

Description

technical field [0001] The present invention relates to a railway vehicle provided with a corner post that absorbs an impact load caused by a collision. Background technique [0002] The corner posts arranged at the four corners of the railway vehicle are required to have high strength in order to protect the interior even in the event of a collision. For example, Patent Document 1 discloses a railway vehicle including a corner post reinforcing member ( 58 ) at a position corresponding to the corner post ( 53 ). [0003] Prior art literature: [0004] Patent documents: [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-235730. Contents of the invention [0006] Problems to be solved by the invention: [0007] The corner posts like this must first be strong, but in addition, it is desirable to be able to absorb the impact load of a vehicle collision. The impact load can be absorbed by the deformation of the corner post (impact energy can be con...
