Abstract

The invention discloses a virtual rail train, its braking system, and its braking method. The braking system includes an electric braking system and an air braking system; the electric braking system includes a braking control unit; The brake control unit is electrically connected to the brake pedals and multiple bridge modules in the cabs at both ends of the train; each bridge module is electrically connected to a brake; The two-way valves are arranged on the first air circuit; the plurality of bridge modules are all connected to one port of the two-way valve; each bridge module is connected to the port of the two-way valve. moving valve. In the present invention, a relay valve is arranged on the pipeline close to the bridge module to accelerate the discharge of compressed air, which greatly shortens the braking release time.

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...
