CONTROL DRIVE OF THE PLUG DOOR OF THE VEHICLE Russian patent published in 2023 - IPC B60J5/06 E05D15/08 

FIELD: transport engineering.

SUBSTANCE: invention relates to the field of transport engineering, in particular to control devices for plug door flaps, and can be used on rail and motor vehicles. The control drive of the plug door of the vehicle comprises a plug door mechanism that ensures the movement of at least one door flap in mutually perpendicular planes, equipped with external and internal frames and at least one carriage with an engine coupled to the door flap installed with the possibility of moving in planes perpendicular and parallel to the axis of the vehicle by the control L-shaped groove interacting through the drive roller with the carriage of the door flap. The crank mechanism is pivotally coupled to the outer frame. The inner frame is made in the form of a movable lead screw mounted on wheels interacting with the grooves of the outer frame with at least one carriage mounted movably on it with a nut installed inside it, which is able to rotate together with the lead screw by means of transmission, for example, a gear-belt gear relative to the carriage or rotating to move along a helical line relative to fixed lead screw, depending on the position of the carriage drive roller in a short transverse or long longitudinal section of the control L-shaped groove, mounted horizontally on the outer frame. The carriage with the door flap moves in a plane perpendicular or parallel to the axis of the vehicle, moving along the screw, and the cranks of the crank mechanism are rigidly connected to the ends of the screw and installed with the ability to rotate synchronously with the screw at an angle greater than 180°, moving the lead screw perpendicular to the axis of the vehicle, and then fix the lead screw with the carriage and the door flap in the position retracted inwards or extended outwards from the doorway position.

EFFECT: simplification of the kinematic scheme of the mechanism of movement of door flaps in mutually perpendicular planes is provided.
