The invention discloses a train brake shoe, a train brake device and a train. The brake shoe comprises a fixed shell, an adjusting support, a tile and a plurality of brake nails; the adjusting support is installed on the fixing shell in a sliding mode and driven by a pressure mechanism arranged in the fixing shell to slide. The tile is arc-shaped and fixed at one end of the adjusting support away from the fixed shell; the brake nails are evenly distributed in the adjusting support in a sliding mode and driven by corresponding servo electric cylinders arranged in the adjusting support to slide, the outer ends of the brake nails stretch out of the tiles, the inner ends of the brake nails are matched with the corresponding servo electric cylinders, and pressure sensors used for monitoring pressure in real time are arranged between the brake nails and the corresponding servo electric cylinders. The brake device comprises an axle and a plurality of brake shoes arranged on the radial side of the axle; the train comprises a train body and the train braking device, and the train braking device is installed on the train body. Friction vibration generated during braking is balanced, a train is more stable during braking, and the situation that parts are fractured and damaged due to friction collision and non-attachment caused by unstable braking can be prevented.
本发明公开了一种列车制动闸瓦、列车制动装置及列车;闸瓦包括固定壳、调节托、瓦片及若干制动钉;调节托以可滑动方式安装于固定壳并由设在固定壳内的压力机构驱动滑动;瓦片呈弧形并固定在调节托远离固定壳的一端;各制动钉以可滑动方式均匀分布于调节托内并由设在调节托内的相应伺服电动缸驱动滑动,制动钉的外端从瓦片伸出、内端与相应伺服电动缸配合且二者之间设有用于实时监测压力的压力传感器;制动装置包括车轴及若干设于车轴径向侧的闸瓦;列车包括车体和列车制动装置,列车制动装置安装于车体上。本发明有利于平衡制动时产生的摩擦振动,使制动时列车更加平稳,可以防止零部件因制动不平稳产生摩擦碰撞、不贴合而出现断裂损伤。
