Brakes, rail transit braking systems and rail transit systems

Abstract

The invention discloses a brake, a rail traffic braking system and a rail traffic system. The brake includes a motor, a moving mechanism and an emergency braking mechanism. Removably connected with the main shaft of the motor, the kinematic mechanism is provided with a second brake pad, and the kinematic mechanism is configured to convert the rotational motion of the main shaft of the motor into the linear motion of the second brake pad, and the second brake pad is placed on the kinematic mechanism. Push down and clamp the brake disc of rail transit. The emergency braking mechanism is set on the brake caliper body and locks the moving mechanism in the axial direction of the moving mechanism. The emergency braking mechanism is configured to unlock the movement when emergency braking The mechanism drives the second brake pad to move toward the first brake pad by pushing the moving mechanism to clamp the brake disc of the rail transit. The brake used in the rail transit braking system according to the embodiment of the present invention has the advantages of simple structure, high transmission efficiency, sensitive response, and easy assembly and maintenance.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a brake, a rail transit braking system and a rail transit system. Background technique [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. As a result, there are many pipelines in the braking system, which leads to a complex structure, a large volume, and an inefficient braking system. It is convenient for layout, and the use of hydraulic braking system or pneumatic braking system also has the problems of slow braking response and low transmission efficiency. Environmental pollution. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose a brake for a rail transit braking system, which is simple in structu...

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
