Title (EN) RAILROAD CAR BOGIE, RAILROAD CAR, AND TRAIN
(FR) BOGIE DE WAGON DE CHEMIN DE FER, VOITURE DE CHEMIN DE FER ET TRAIN
(JA) 鉄道車両用台車、鉄道車両及び列車
Abstract:
(EN) The present invention reduces aerodynamic sound generated from a bogie in addition to wheel rolling noises and wind noises emanating from brake discs, and reduces the amount of snow clinging to the bogie from snow which has accumulated on a track in winter, while ensuring traveling stability, curving performance when traveling through a curved section, and safety without introducing restrictions on the dimensions and arrangement of the components of the bogie. This railroad car bogie 1 includes a bogie frame 2, axle boxes 4 supported by the bogie frame 2, and wheel sets 3 supported by the axle boxes 4. For example, covers 13 which each cover both ends of the wheel sets 3 on the inside of the bogie frames 2 and cover the front and rear ends of a bogie 1 in the vehicle traveling direction are mounted to the bogie 1.
(FR) La présente invention réduit le son aérodynamique produit par un bogie, en plus des bruits de roulement de roues et des bruits du vent provenant des disques de frein. Elle réduit la quantité de neige adhérant au bogie provenant de la neige s'accumulant sur une voie ferrée en hiver, tout en assurant une stabilité de déplacement, une performance dans les virages lors de déplacement dans une section incurvée, et une sécurité sans introduire de restrictions sur les dimensions et l'agencement des éléments du bogie. Ce bogie de wagon de chemin de fer (1) comprend un châssis de bogie (2), des boîtes d'essieu (4) soutenues par le châssis de bogie (2), et des ensembles de roues (3) soutenus par les boîtes d'essieu (4). Par exemple, des couvercles (13) couvrant chacun les deux extrémités des ensembles de roues (3) sur l'intérieur des châssis de bogie (2) et couvrant les extrémités avant et arrière d'un bogie (1) dans la direction de déplacement de véhicule sont montés sur le bogie (1).
(JA) 台車の構成部品の寸法や配置に制約を課さず、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、車輪転動音とブレーキディスクから放射される風切り音に加えて、台車から発生する空力音や冬季に軌道上に積もった雪が台車に付着することも低減する。 台車枠2、台車枠2に支持される軸箱4、及び軸箱4に支持される輪軸3を含む鉄道車両用台車1である。例えば、台車1に、台車枠2の内側で輪軸3の両端を覆い、かつ、台車1の車両進行方向の前後端部を覆うカバー13を取付ける。
