The invention discloses a brake device for rail transit. The brake device comprises a movable disc seat, a movable disc, a static disc, a bearing, a shell and a cylinder cover. The movable disc seat is pressed on the axle in an interference mode, the bearings are installed on the two sides of the movable disc seat, and the movable disc and the movable disc seat are installed in a matched mode and rotate circumferentially along with the axle. The static discs are arranged on the two sides of the movable disc, the static discs and the shell are installed in a matched mode, meanwhile, the shell is installed on one bearing, and the outer side of the shell is connected to a bogie swing arm to restrain circumferential rotation. The cylinder cover is mounted on the other bearing, and an oil cylinder brake shoe stack adjuster and an oil way are mounted on the cylinder cover; the edge of the shell and the edge of the cylinder cover are connected in the circumferential direction to package the movable disc and the static disc. When a vehicle is braked, pressure is applied to the oil cylinder through the oil way on the cylinder cover, the oil cylinder pushes the static disc to press the movable disc, and the movable disc and the static disc enable axle wheels to decelerate until the axle wheels are static through pressure friction torque. The braking device has the axial floating adaptation characteristic, meanwhile, the friction area is increased, and the braking heat bearing capacity is improved.

    本发明公开了一种用于轨道交通的制动装置,包括动盘座、动盘、静盘、轴承、壳体和汽缸盖。动盘座过盈压装在车轴上,轴承安装于动盘座的两侧,动盘和动盘座配合安装随车轴周向旋转;静盘设置于动盘的两侧,静盘和壳体配合安装,同时壳体安装于其中一个轴承上且外侧连接至转向架摆臂约束周向旋转;汽缸盖安装于另一个轴承上,同时其上安装有油缸闸调器和油路;壳体和汽缸盖边缘沿周向连接将动盘和静盘进行封装。车辆制动时,通过汽缸盖上的油路给油缸施压,油缸推动静盘压紧动盘,动盘和静盘通过压力摩擦扭矩来使车轴车轮减速直至静止。本发明的制动装置具有轴向浮动适应特性,同时增加了摩擦面积,提高了制动热承载能力。
