Title (EN) BRAKE LINING FOR RAILWAY VEHICLE, AND DISC BRAKE WITH SAME
(FR) GARNITURE DE FREIN POUR VÉHICULE FERROVIAIRE ET FREIN À DISQUE ÉQUIPÉ DE CETTE GARNITURE
(JA) 鉄道車両用ブレーキライニングおよびそれを備えたディスクブレーキ
Abstract:
(EN) A disc brake for a railway vehicle uses a floating brake caliper. The disc brake is configured so that a lining which is held by a caliper arm located on the side where a pressing drive source is not provided comprises: a friction member which faces the sliding surface of the disc affixed to either a wheel or an axle of the railway vehicle; a base plate which holds at the front surface thereof the friction member; and a guide plate which is secured to the center of back surface of the base plate and which is received in a recess in the caliper arm. The front surface of the base plate is parallel to the sliding surface of the friction member, the thickness of the base plate is greater on the inner peripheral side thereof than on the outer peripheral side thereof, the thickness of the guide plate is less than the depth of the recess in the caliper arm, and the guide plate is loosely fitted in the recess in the caliper arm with the sliding surface of the friction member facing the sliding surface of the disc so as to be parallel thereto. As a result of this configuration, the durability of the disc brake is improved on the side where the pressing drive source is not provided.
(FR) L'invention porte sur un frein à disque pour un véhicule ferroviaire qui utilise un étrier de frein flottant. Le frein à disque est conçu de telle sorte qu'une garniture, qui est maintenue par une branche de l'étrier située sur le côté où une source d'entraînement de pression n'est pas fournie, comporte : un élément de friction qui fait face à la surface de glissement du disque fixé soit à une roue, soit à un essieu du véhicule ferroviaire ; une plaque de base qui maintient l'élément de friction sur sa surface avant ; une plaque de guidage qui est fixée au centre de la surface dorsale de la plaque de base et qui est reçue dans un renfoncement dans la branche d'étrier. La surface avant de la plaque de base est parallèle à la surface de glissement de l'élément de friction, l'épaisseur de la plaque de base est plus grande sur son côté périphérique intérieur que sur son côté périphérique extérieur, l'épaisseur de la plaque de guidage est inférieure à la profondeur du renfoncement dans la branche d'étrier et la plaque de guidage est disposée de façon lâche dans le renfoncement dans la branche d'étrier, la surface de glissement de l'élément de friction faisant face à la surface de glissement du disque de manière à être parallèle à celle-ci. La durabilité du frein à disque est améliorée, par cette configuration, sur le côté où une source d'entraînement de pression n'est pas fournie.
(JA)  フローティング式ブレーキキャリパを用いた鉄道車両用ディスクブレーキにおいて、押付け駆動源が配設されていない側のキャリパアームに保持されるライニングは、鉄道車両の車輪または車軸に固定されたディスクの摺動面と対向する摩擦部材と、摩擦部材を正面に保持する基板と、基板の背面の中央に固設され、キャリパアームの凹部に収容される案内板と、から構成され、基板の正面が摩擦部材の摺動面と平行であり、基板の厚みが、外周側よりも内周側で厚くなっており、案内板の厚みがキャリパアームの凹部の深さよりも薄くなっており、摩擦部材の摺動面がディスクの摺動面と平行に対向した状態で、案内板がキャリパアームの凹部に遊嵌する。これにより、反押付け駆動源側で、ディスクブレーキの耐久性を向上させることができる。
