Document Type and Number:
Japanese Patent JP2023022552
Kind Code:
A
Abstract:
To provide a railway vehicle cap beam structure which extends a light weightiness and a high rigidity, while contributing to improvement of a vehicle body assembly and securing a prescribed space between the cap beam and an underframe, and to provide a railway vehicle with the cap beam structure.SOLUTION: A cap beam structure of a cap beam installed on an underframe constituting a floor of a railway vehicle body structure is formed by bonding plural shaped materials of multilayer structures whose extrusion direction is a width direction of the body structure. The plural shaped materials include a first shaped material which has an upper projecting part to project upward and has a region lacking a part of the upper projecting part layer in a central part in a width direction of the body structure and include a second shaped material which has not the upper projecting part and comprise a fastening component installed on the shaped material of the second shaped material of the cap beam at both end parts in the width direction of the body structure and couple the cap beam on the side beam via the fastening face of the fastening component.SELECTED DRAWING: Figure 3
