To provide the brake equipment for railway vehicle capable of reducing the risk in which a reduction gear damages by a brake reaction force.SOLUTION: The brake equipment 1 for railway vehicle in this embodiment comprises a conversion mechanism 30 having: an electric motor 2; a reduction gear 20 having an output rotation body 21 which outputs the torque inputted from the electric motor 2; an input rotation body 31 in which the torque outputted from the output rotation body 21 is inputted; and a direct-acting component 32 converting the rotary motion of the input rotation body 31 into the linear motion in moving directions VA, VB parallel to the rotational axis of the rotation body 31, and the friction materials 40A, 40B to which the linear motion of the direct-acting component 32 is communicated to brake the railway vehicle. The input rotation body 31 is movable relatively to the output rotation body 21 in the moving directions VA, VB and is provided so as to be capable of communicating the rotary motion of the output rotation body 21 to the direct-acting component 32.SELECTED DRAWING: Figure 2
【課題】ブレーキ反力によって減速機が損傷する可能性を低減できる鉄道車両用制動装置を提供する。【解決手段】実施形態の鉄道車両用制動装置1は、電動機2と、電動機2から入力された回転力を出力する出力回転体21を有する減速機20と、出力回転体21から出力された回転力が入力される入力回転体31と、入力回転体31の回転運動を入力回転体31の回転軸と平行な移動方向VA,VBの直線運動に変換する直動部材32と、を有する変換機構30と、直動部材32の直線運動が伝達されて鉄道車両を制動する摩擦材40A,40Bと、を備える。入力回転体31は、出力回転体21に対して移動方向VA,VBに相対移動可能であり、かつ、出力回転体21の回転運動を直動部材32に伝達可能に設けられる。【選択図】図2
