PROBLEM TO BE SOLVED: To provide a brake shoe for a vehicle capable of suppressing brake noise (sound) when braking is made.SOLUTION: A brake shoe 1 for a vehicle makes slide contact to a wheel tread of a railway vehicle to brake a wheel, and on a front side of a base metal (back plate) 5, a slide material body 2 otherwise the slide material body 2, a vibration-proof material 3, a rivet material, and a deformed alloy are arranged, vibration-proof pads 4a and 4b are arranged at least at a part of a rear side of the base metal 5, and the vibration-proof pads 4a and 4b and the slide material body 2 otherwise the slide material body 2 and the vibration-proof material 3 are integrated at a portion of a hole 15 opened at a part of the base metal 5. Thus, direct contact between a brake shoe holder and the brake shoe is prevented, and by arrangement of a combination of a single or a plurality of buffer materials in between, a brake noise (sound) is suppressed when braking, for high durability and less possibility of peeling and breakage during use.SELECTED DRAWING: Figure 1
【課題】ブレーキをかけた際にブレーキ音(鳴き)を抑えることができる車両用制輪子を提供する。【解決手段】鉄道車両の車輪踏面に摺接して車輪にブレーキをかけるための車両用制輪子1であって、台金(背板)5の前面に摺動材本体2又は摺動材本体2と防振材3、及びリベット材や変形させた台金が配置され、台金5の後面の少なくとも一部には防振パッド4a,4bが配置され、防振パッド4a,4bと摺動材本体2又は摺動材本体2と防振材3とは台金5の一部に開けた孔15の部分で一体化されている。これにより、制輪子ホルダーと制輪子の直接触を防ぎ、間に前述の緩衝材を1種類または複数の組み合わせで配置する事により、ブレーキをかけた際にブレーキ音(鳴き)を抑えることができ、かつ耐久性が高く、使用中に剥がれたり壊れるおそれが少ない。【選択図】図1
