Railroad vehicle

Abstract

The present invention provides a railroad vehicle having a truck structure in which soundproof effect can sufficiently be enhanced. Soundproof member 22 having flexibility is mounted to support member 21 fixed to axle box 15 . The support member is fixed to the axle box at an outer side of a vehicle body at wheel 14 in such a manner that the lower end thereof is located above a position set beforehand. The soundproof member is arranged parallel to the rail at the outer side of the vehicle body at the position where the wheel rolls on rail 17 . The upper part of the soundproof member is mounted to the support member in such a manner that the position thereof in the vertical direction can be adjusted, and the lower end of the soundproof member is located above a surface of the rail.

1 . A railroad vehicle including a truck in which both ends of an axle respectively mounted to a wheel are supported by an axle box so as to be capable of rotating, the railroad vehicle comprising: a metallic support member fixed to the axle box; and a soundproof member having flexibility and is mounted to the support member, wherein the support member is mounted at an outer side of the vehicle body at the wheel such that an upper part thereof is fixed to the axle box in a state in which a lower end thereof is located above a position set beforehand, and the soundproof member is arranged in a direction parallel to a rail at the outer side of the vehicle body at a position where the wheel rolls on the rail, wherein the upper part of the soundproof member is attached to the support member, while the lower end of the soundproof member is located above a surface of the rail.
