The invention discloses a virtual rail train and a braking system, a braking method and a braking system thereof. The braking system comprises an electric control braking system and an air braking system, the electric control braking system comprises a braking control unit; the braking control unit is electrically connected with braking pedals and a plurality of axle modules in driver's rooms at the two ends of a train. Each bridge module is correspondingly and electrically connected with one brake; the air braking system comprises a first air path, and the two braking pedals are communicatedthrough a two-way valve arranged on the first air path. The plurality of bridge modules are communicated with one port of the two-way valve; and a relay valve is arranged on an air path between each bridge module and the port of the two-way valve. The relay valve for accelerating compressed air discharge is arranged on the pipeline close to the bridge module, so that the brake release time is greatly shortened.
Description
technical field [0001] The invention relates to the technical field of super virtual rail train braking, in particular to a virtual rail train, a braking system and a braking method thereof. Background technique [0002] Super virtual rail trains are usually equipped with an electronically controlled braking system and a pure air braking system: the electronically controlled braking system receives the electrical signal of the brake pedal from the brake control unit, and the control bridge module outputs the pressure of the brake cylinder; the pure air braking system Then the control air circuit of the brake pedal outputs the control pressure to the bridge module, and the bridge module outputs the pressure of the brake cylinder. [0003] Super virtual rail train formation leader, a large number of axles, and a long brake pipeline path. When the driver steps on the brake pedal and releases it quickly, although the electronic control brake system can quickly discharge the pres...
