The invention discloses a brake, a rail transit brake system and a rail transit system. The brake comprises a brake caliper body, a motor, a screw pair mechanism, a cross arm and a first elastic piece. A first brake pad is arranged on the brake caliper body; the screw pair mechanism is connected with a spindle of the motor; the cross arm is arranged at the second end of the screw pair mechanism ina sleeving mode and provided with a second brake pad, and the second brake pad is pushed by the screw pair mechanism to move towards the first brake pad so as to clamp a brake disc of rail transit. The first end of the first elastic piece is connected with the brake caliper body, the second end of the first elastic piece is connected with the cross arm, and the second brake pad is pushed by the first elastic piece to move towards the first brake pad so as to clamp the brake disc of rail transit. Therefore, through cooperation of the brake caliper body, the motor, the screw pair mechanism, thecross arm and the first elastic piece, the brake response speed of the brake can be increased, the working efficiency of the brake can be improved; and the brake is not provided with a hydraulic brake pipeline, so that the mass of the whole vehicle can be effectively reduced.

    本发明公开了一种制动器、轨道交通制动系统以及轨道交通系统,制动器包括:制动钳体、电机、螺旋副机构、横臂和第一弹性件。制动钳体上设有第一制动片;螺旋副机构与电机的主轴连接;横臂套设于螺旋副机构的第二端,横臂设有第二制动片,第二制动片在螺旋副机构推动下向第一制动片移动以夹紧轨道交通的制动盘;第一弹性件的第一端与制动钳体连接,第一弹性件的第二端与横臂连接,第二制动片在第一弹性件的推动下向第一制动片移动以夹紧轨道交通的制动盘。由此,通过制动钳体、电机、螺旋副机构、横臂和第一弹性件配合,能够提升制动器的制动响应速度,可以提高制动器的工作效率,并且,该制动器没有液压制动管路,可以有效降低整车质量。
