Abstract | This railway vehicle steering truck is provided with: a truck frame; a wheel set; an axle box supporting device; a steering mechanism that steers the wheel set; a brake unit; and a brake unit supporting link. The brake unit has a body frame and a brake shoe, which is supported by the body frame and pressed against the wheel tread during braking. The brake unit supporting link couples the axle box supporting device and the brake unit, and transmits the displacement in the vehicle longitudinal direction of an axle box to the brake unit at least during the steering by the steering mechanism. The brake unit supporting link restrains the brake unit from being displaced a predetermined amount or more outward in the vehicle width direction during braking. The side surface of the brake unit supporting link and/or the side surface of the brake unit has a sliding surface.
L'invention concerne un bogie de direction de véhicule ferroviaire comprenant : un châssis de bogie ; un essieu monté ; un dispositif support de boîte d'essieu ; un mécanisme de direction qui dirige l'essieu monté ; une unité de frein ; et une barre de liaison supportant l'unité de frein. L'unité de frein possède une ossature de caisse et un sabot de frein qui est supporté par l'ossature de caisse et pressé contre la table de roulement de la roue pendant le freinage. La barre de liaison supportant l'unité de frein accouple le dispositif support de boîte d'essieu et l'unité de frein et transmet le déplacement dans le sens longitudinal du véhicule d'une boîte d'essieu à l'unité de frein au moins pendant la direction par le mécanisme de direction. La barre de liaison supportant l'unité de frein retient l'unité de frein afin qu'elle ne soit pas déplacée d'une quantité prédéterminée ou davantage vers l'extérieur dans le sens de la largeur du véhicule pendant le freinage. La surface latérale de la barre de liaison supportant l'unité de frein et/ou la surface latérale de l'unité de frein présentent une surface de glissement.
鉄道車両用操舵台車は、台車枠と、輪軸と、軸箱支持装置と、輪軸を操舵させる操舵機構と、ブレーキユニットと、ブレーキユニット支持リンクと、を備える。ブレーキユニットは、本体フレームと、当該本体フレームに支持され、ブレーキ制動時に車輪の踏面に押し付けられる制輪子とを有する。ブレーキユニット支持リンクは、軸箱支持装置とブレーキユニットとを連結し、少なくとも操舵機構による操舵時に、軸箱の車両長手方向の変位をブレーキユニットに伝達する。ブレーキユニット支持リンクは、ブレーキ制動時にブレーキユニットが車幅方向外側に所定以上に変位するのを規制する。ブレーキユニット支持リンクの側面及びブレーキユニットの側面の少なくともいずれか一方に摺動面を有する。 |
