PROBLEM TO BE SOLVED: To reduce rolling noise generated by a wheel and a rail, and wind noise generated by a brake disk, while securing stability during linear traveling and furthermore stability during high speed traveling as well as passing performance and safety during curved section traveling.SOLUTION: Provided is a carriage for a railway vehicle, that supports a wheel shaft in a freely rotatable manner. In the case where a brake disk is mounted to a plate part of a wheel 1 constituting the wheel shaft or to the wheel 1, noise insulation covers 11 to 14 are attached so as to cover the plate part of the wheel 1 and the brake disk mounted to the plate part of the wheel 1. Accordingly, it is possible to reduce environmental noise called wheel rolling noise and aerodynamic noise emitted from the brake disk, without imposing restrictions on dimensions and arrangement of components of the carriage, while securing stability during linear traveling, and furthermore stability during high speed traveling as well as passing performance and safety during curved section traveling.

    【課題】直線走行時の安定性、さらには高速走行時の安定性、曲線区間走行時の通過性能、安全性を確保しつつ、車輪及びレールから発生する転動音やブレーキディスクから発生する風切り音を低減する。【解決手段】輪軸を回転自在に支持する鉄道車両用台車である。輪軸を構成する車輪1の板部、或いは車輪1にブレーキディスクが設置されている場合は、車輪1の板部と車輪1の板部に設置されたブレーキディスクを覆うように防音カバー11〜14を取り付ける。【効果】台車の構成部品の寸法や配置に制約を課すことなく、直線走行時の安定性、さらには高速走行時の安定性、曲線区間走行時の通過性能、安全性を確保し、車輪転動音とブレーキディスクから放射される空力音という環境騒音を低減することができる。【選択図】図14
