The invention relates to the technical field of sliding plug door transmission mechanisms, and discloses a sliding plug door transmission mechanism for railway vehicles, which comprises a fixing frame, a separating mechanism is arranged in the fixing frame, a connecting mechanism is arranged in the fixing frame, the separating mechanism comprises a limiting frame, and the outer surface of the limiting frame is fixedly connected with the inner wall of the fixing frame. The right side face of the limiting frame is fixedly connected with a supporting frame, the bottom face of the supporting frame is fixedly connected with the upper surface of the fixing frame, and the inner wall of the supporting frame is rotationally connected with a first threaded rod. According to the sliding plug door transmission mechanism for the railway vehicle, a lifting plate can pull a first servo motor at the bottom to ascend in the upward ascending process, the first servo motor ascends to drive a connecting gear ring on the surface to ascend at the same time, and then the connecting gear ring can slide and be separated on the surface of a driving gear; when a driving source of the sliding plug door breaks down, the driving assembly can be separated, and then follow-up emergency control work can be facilitated.
本发明涉及塞拉门传动机构技术领域,且公开了一种用于轨道车辆的塞拉门传动机构,包括固定架,所述固定架的内部设置有分离机构,固定架的内部设置有连接机构,分离机构包括限位框,限位框的外表面与固定架的内壁固定连接,限位框的右侧面固定连接有支撑框,支撑框的底面与固定架的上表面固定连接,支撑框的内壁转动连接有第一螺纹杆。该用于轨道车辆的塞拉门传动机构,升降板向上上升的过程中能够拉动底部的第一伺服电机进行上升,第一伺服电机上升能够带动表面的连接齿环同时进行上升,进而能够使连接齿环在驱动齿轮的表面进行滑动分离,便于在塞拉门的驱动源出现故障时能够使驱动组件分离开,进而能够便于后续的应急控制工作。
