Abstract
The invention relates to a superhigh-speed maglev train shuttle which belongs to the field of rail traffic. The invention aims at improving the current speed per hour by one time and reducing the derailing coefficient to the minimum on the basis of the coupled running of Harmony CRH2C maglev trains. A top rail is fixed by an annular sleeper, two groups of constant-height top wheels on each compartment roll under the guide of the top rail through grooves, and the jump stress of the compartment is counteracted to avoid derailing. An YQ365 type traction motor is changed into a 4/2 variable-pole double-speed motor, poles are changed by the operation of a 4/2 variable-pole relay during the running of a maglev train, and all motor rated rotating speed is synchronously doubled. The original 4-pole running speed per hour (300-350km per hour) is increased to the current 2-pole running speed which is more than or equal to 612km per hour. During brake, an electromagnetic cross beam coil is electrified to magnetize a concentric brake shoe and enable the brake shoe and two rails to be pulled in, and the brake force can be adjusted through the adjustment of current intensity. A pneumatic brake element is arranged on the concentric brake shoe in an overlaying manner, and the original direct-acting pneumatic brake manner of the train is reserved in a matching manner, so that the maglev train can be ensured to be directly braked by the rails under power-off non-voltage emergency conditions.
