To provide a railway vehicle yaw damper gear by which vehicle body vibrations in a vertical direction caused by pitching of a truck is easily suppressed and drive comfort in the railway vehicle can be improved.SOLUTION: A yaw damper gear 100 in this invention is constituted of a pair of yaw dampers 1a, 1b both arranged in the forward and backward directions of a truck 3 and each of pairs of yaw dampers is installed in the left or right side of the truck. The first yaw damper 1a of the pair of yaw damper which is positioned in an end side of the vehicle body 2 has an end E1 and another end E2, the former being positioned in an end side of the vehicle body and attached to the truck and the latter being attached to the vehicle body. The second yaw damper 1b positioned in a center side of the vehicle body has an end E2 and another end E1, the former being positioned in the end side of the vehicle body and attached to the vehicle body and the latter being attached to the truck. The end E2 of the first yaw damper and the end E2 of the second yaw damper are respectively attached to each positions which exist symmetrically above and below a center C of pitching of the truck and are mutually and vertically separated.SELECTED DRAWING: Figure 1
【課題】台車のピッチングに起因した車体の上下方向の振動を容易に低減して鉄道車両の乗り心地を向上させることが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、台車3の前後方向に並設された1対のヨーダンパ1a、1bを台車の左右それぞれに備え、1対のヨーダンパのうち、車体2の端部側に位置する第1ヨーダンパ1aは、車体の端部側に位置する一方の端部E1が台車に取り付けられ、他方の端部E2が車体に取り付けられている。車体の中央側に位置する第2ヨーダンパ1bは、車体の端部側に位置する一方の端部E2が車体に取り付けられ、他方の端部E1が台車に取り付けられている。第1ヨーダンパ1aの他方の端部E2と、第2ヨーダンパ1bの一方の端部E2とは、台車のピッチング中心Cを挟んで上下方向に互いに離間した位置に取り付けられている。【選択図】 図1
