The invention discloses a braking system of a railway vehicle and a control method thereof, and aims to solve the problem that in the prior art, when the railway vehicle adopts a hydraulic braking system or gas-to-liquid type braking system, the requirements for the performance of hydraulic oil at various temperatures and the leak tightness of pipelines are higher. The braking system comprises a gas pressurization device, a basic braking device and a control device, wherein one end of the gas pressurization device is connected with the basic braking device, and the other end of the gas pressurization device is connected with the control device, so that a controlled device is controlled to increase the pressure of a braking clamp of the vehicle to the level required by braking; and the control device is used for controlling the gas pressurization device to conduct a braking pressurization gas path after receiving an external braking command, receiving pressure information of the braking clamp returned by the pressurization device, and controlling the pressurization device to close the braking pressurization gas path when the pressure of the braking clamp reaches the level required by braking. Compared with the pressurization mode of the railway vehicle in the prior art, the braking system is safer, more reliable and more environment-friendly.
Description
technical field [0001] The invention relates to the field of vehicle braking, in particular to a braking system and control method for rail vehicles. Background technique [0002] Medium and low-speed maglev trains remove the wheels, and rely on electromagnetic suction to levitate the vehicle to a certain height. When braking, the braking process is realized by the combined action of electric braking and mechanical braking. Among them, the mechanical braking is achieved by the friction force generated by the brake caliper close to the wing edge of the F rail. Due to the limitation of the space position, the structure size of the clamp is relatively small, and based on the consideration of the safety of the vehicle, the vehicle has higher requirements on the braking deceleration. At the same time, the braking force generated by the wind source of the general-purpose vehicle braking system acting on the clamps is small, and it is difficult to meet the requirements of braking ...
