RAILCAR
Document Type and Number:
WIPO Patent Application WO/2017/179480
Kind Code:
A1
Abstract:
In order to effectively mitigate the vertical bending vibrations of the car body of a railcar even when the eigenfrequency of those vibrations is different from the cars in the same consist and thereby improve riding comfort in the railcar, the present invention provides a railcar comprising a car body, a first bogie supporting one end of the car body, and a second bogie supporting the other end of the car body, characterized in that the railcar has a first connection member that connects the car body and the first bogie along the longitudinal direction of the car body and a second connection member that connects the car body and the second bogie along the longitudinal direction of the car body, wherein the mounting height of the first connection member, which is the front-rear coupling element for one bogie arranged between the car body and the one bogie, relative to the track is different from the mounting height of the second connection member, which is the front-rear coupling element for the other bogie arranged between the car body and the other bogie, relative to the track.
