CONTROL SYSTEM OF PNEUMATIC DRIVE OF PASSENGER WAGON SLIDING PLUG DOOR Russian patent published in 2018 - IPC B61D19/02 B60J5/06

Abstract RU 2661254 C1

FIELD: transportation.

SUBSTANCE: invention relates to railway transport. Control system for the pneumatic drive of the sliding plug door consists of first pneumatic cylinder (2) of the chain drive mechanism of the opening of the sliding plug door, which has a door opening cavity extending from the doorway, and the cavity of closing the door, second pneumatic cylinder (11), movable unit extension mechanism (6) having movable block extension chamber (14) and mobile unit return cavity (15), pneumatic cylinder piston position sensors. Source of compressed air is connected by the first and second pneumatic lines from each of the cavities of the pneumatic cylinder of the chain drive and the pneumatic cylinder of the moving unit extension mechanism. Pneumatic line connecting the door opening cavity of the pneumatic cylinder of the chain drive with the electro-pneumatic distributor is connected to the extension cavity of the mobile unit, and a pneumatic line connecting the door closing cavity of the pneumatic cylinder of the chain drive with the electro-pneumatic distributor is connected to the return cavity of the mobile cylinder block of the movable unit extension mechanism.

EFFECT: invention excludes the possibility of opening the door when the train is moving.
