The invention relates to a rail transit braking device. The rail transit braking device comprises a braking mechanism and a parking mechanism, wherein the brake mechanism comprises a brake motor, a worm driven by the brake motor, a worm wheel orthogonally meshed with the worm, a brake screw rod driven by the worm wheel, and a brake nut which is spirally arranged on the brake screw rod, can linearly move along the axial direction of the brake screw rod and is used for outputting brake force to the brake shoe assembly, wherein the parking mechanism comprises a parking motor, a parking screw roddriven by a parking motor and a brake block which is spirally arranged on the parking screw rod and can linearly move in the axial direction of the parking screw rod, and the brake block is used for clamping a worm in the radial direction, so the worm is static, the braking torque is kept, and parking braking of a train is achieved. The rail transit braking device is advantaged in that the parkingmechanism part of the braking device is powered by an independent motor, power is transmitted to a parking lead screw in a turning mode through a bevel gear pair, and a brake block is driven to execute holding brake parking operation.

    本发明涉及一种轨道交通制动装置,包括制动机构和驻车机构;制动机构包括:制动电机、由制动电机驱动的蜗杆、与蜗杆正交啮合的蜗轮、由蜗轮驱动的制动丝杆、螺旋设置于该制动丝杆且可沿该制动丝杆轴向直线运动的用于对闸瓦组件输出制动力的制动螺母;驻车机构包括:驻车电机、由驻车电机驱动的驻车丝杆、螺旋设置于该驻车丝杆且可沿该驻车丝杆轴向直线运动的制动块,所述制动块用于在径向方向上夹持蜗杆,使蜗杆静止,保持制动力矩,实现列车的驻车制动。本制动装置驻车机构部分由独立的电机提供动力,经过锥齿轮副实现动力变向传递给驻车丝杆,带动制动块执行抱刹驻车操作。
