Problems solved by technology

[0003] However, the hydraulic brakes currently used in maglev trains need to use an external medium, that is, oil pressure to output the braking force, which increases the response time of the brakes and further increases the safety hazards of maglev trains.

Abstract

The present invention provides an outer pliers body, comprising: an outer pliers body, the outer pliers body is provided with a through hole; a motor assembly, the motor assembly has an output shaft; a first transmission assembly, the first transmission assembly includes : a transmission nut, the transmission nut passes through the through hole, the transmission nut is connected with the through hole in relative rotation, and the transmission nut is connected with the output shaft; a transmission screw, the transmission screw passes through the Through the transmission nut, the transmission lead screw and the transmission nut are in drive connection with each other, and the drive lead screw is relatively movable connected with the outer pliers body. The outer caliper body provided by the present invention is applied to a brake for a maglev train, uses a motor as a driving force, does not require an external medium, improves the response speed of the brake for a maglev train, and ensures the safety of the operation of the maglev train. The invention also provides a maglev train brake and a brake control method.

Description

technical field [0001] The invention belongs to the field of brakes for maglev trains, and in particular relates to an outer caliper body, a maglev train brake and a braking control method. Background technique [0002] The braking system of maglev trains mainly adopts hydraulic brakes at present. The working process of the hydraulic brake is: the brake control unit calculates the required braking force according to the received braking force demand, sends a hydraulic control signal to the hydraulic control unit, and the hydraulic control unit supplies oil to the hydraulic brake according to the hydraulic control signal, thereby applying the braking force. [0003] However, the hydraulic brakes currently used in maglev trains need to use an external medium, that is, oil pressure to output the braking force, which increases the response time of the brakes and further increases the safety hazards of maglev trains during braking. Contents of the invention [0004] Aiming at ...
