The composition and control requirements of the car door The electronically controlled pneumatic plug door is mainly composed of the driving mechanism of the pneumatic system of the electrical system, the door locking mechanism and the turnover pedal. Its main working process is as follows: when the door closing signal is sent out, the door closing solenoid valve acts, the rodless cylinder pushes the driving mechanism to perform the door closing action, and at the same time, the pedal turns over to close the foot.
In order to facilitate passengers to get on and off, but considering the clearance between the locomotive and the vehicle, the feet of the vehicle should be turned over and put away. When the door is closed in place, the locking mechanism will lock.
