The invention discloses a wheel disc hydraulic braking system and a maglev train, and relates to the field of maglev train hydraulic pressure, the wheel disc hydraulic braking system has a pressure accumulation function, and when a hydraulic power system fails and cannot work, hydraulic oil stored in an energy accumulator can provide an emergency hydraulic oil source for the system; it is ensured that each hydraulic subsystem can provide a hydraulic oil source meeting the requirement for completing corresponding emergency functions; in addition, the system further has a common braking force proportional control function, the energy accumulator can indirectly input hydraulic oil to the wheel disc brake to complete common braking, and a first pressure sensor is used for accurately controlling output of the corresponding hydraulic oil; in addition, the brake release monitoring function and the remote brake release function are further achieved, when brake release needs to be implemented, hydraulic oil in the wheel disc brake is controlled to flow back to the hydraulic oil tank from the proportional electromagnetic valve, and when it is found that the brake is not released, the hydraulic oil in the wheel disc brake is controlled to flow back to the hydraulic oil tank from the two-position three-way valve.
一种轮盘液压制动系统和磁悬浮列车,涉及磁悬浮列车液压领域,本发明具备蓄压功能,当液压动力系统出现故障无法工作时,蓄能器中储存的液压油可以向系统提供应急液压油源,保证液压各子系统能够提供满足完成相应的应急功能的液压油源;另外,本发明还具有常用制动力比例控制功能,蓄能器可以通过向轮盘制动器间接输入液压油,完成常用制动,并利用第一压力传感器对输出相应的液压油进行精准控制;除此之外,还具备制动缓解监控功能和远程制动缓解功,当需要实施制动缓解时,控制轮盘制动器内的液压油从比例电磁阀流回液压油箱,当发现制动不缓解工况时控制轮盘制动器内的液压油从二位三通阀流回液压油箱。
