Problems solved by technology
[0002] The rail transit braking system in the related art usually adopts a hydraulic or pneumatic braking system, and uses hydraulic pressure or pneumatic pressure as the braking energy source. In this way, there are many pipelines in the braking system, which leads to a relatively complicated structure and a large volume, which is not easy to use. It is convenient for layout, and the hydraulic brake system or pneumatic brake system also has the problems of slow brake response and low transmission efficiency, and due to long-term use, there is a risk of leakage of hydraulic oil and brake fluid in the hydraulic pipeline, which is easy to cause environmental pollution

The invention discloses a brake, a rail transit brake system and a rail transit system. The brake comprises a motor, a movement mechanism and an emergency braking mechanism. A brake caliper body is provided with a first brake pad; a movement mechanism is movably connected with a main shaft of the motor along the axial direction; the movement mechanism is provided with a second brake pad, the movement mechanism is configured to convert the rotary motion of the main shaft of the motor into the linear motion of the second brake pad; the second brake block clamps a brake disc of the rail transit under the pushing of the movement mechanism; the emergency braking mechanism is arranged on the brake caliper body and locks the movement mechanism in the axial direction of the movement mechanism, andthe emergency braking mechanism is constructed to unlock the movement mechanism during emergency braking and drive the second brake pad to move towards the first brake pad by pushing the movement mechanism to move so as to clamp a brake disc of rail transit. The brake for the rail transit braking system is simple in structure, high in transmission efficiency, sensitive in response and easy to assemble and maintain.
