PROBLEM TO BE SOLVED: To provide a yaw damper device for a railway vehicle capable of reducing a lateral pressure applied to vehicle wheels when the railway vehicle travels in a transition curve section of a curved railroad.SOLUTION: A yaw damper device 100 of the invention comprises: a yaw damper 1 attached between a vehicle body 3 and each of carriages 4 in a pair; controlling means 2 for switching a damper coefficient of the yaw damper between a first damper coefficient and a second damper coefficient, which is a non-zero value smaller than the first damper coefficient. When the railway vehicle travels in an entrance side transition curve section, the control means switches the damper coefficient of the yaw damper attached to a front side carriage to the second damper coefficient, while switching the damper coefficient of the yaw damper attached to a rear side carriage to the first damper coefficient. When the railway vehicle travels in an exit side transition curve section, the control means switches the damper coefficient of the yaw damper attached to the front side carriage to the first damper coefficient, while switching the damper coefficient of the yaw damper attached to the rear side carriage to the second damper coefficient.SELECTED DRAWING: Figure 1

    【課題】鉄道車両が曲線軌道の緩和曲線区間を走行する際に車輪に生じる横圧を低減可能な鉄道車両用ヨーダンパ装置を提供する。【解決手段】本発明に係るヨーダンパ装置100は、車体3と1対の台車4のそれぞれとの間に取り付けられたヨーダンパ1と、ヨーダンパの減衰係数を第1減衰係数と該第1減衰係数よりも小さく且つ0ではない第2減衰係数との間で切り替え制御する制御手段2とを備える。制御手段は、鉄道車両が入口側緩和曲線区間を走行する際には、前側の台車に取り付けられたヨーダンパの減衰係数を第2減衰係数にする一方、後側の台車に取り付けられたヨーダンパの減衰係数を第1減衰係数にする。鉄道車両が出口側緩和曲線区間を走行する際には、前側の台車に取り付けられたヨーダンパの減衰係数を第1減衰係数にする一方、後側の台車に取り付けられたヨーダンパの減衰係数を第2減衰係数にする。【選択図】 図1
