Sliding plug door bearing driving mechanism for urban rail vehicle
The invention discloses a sliding plug door bearing driving mechanism for an urban rail vehicle. The sliding plug door bearing driving mechanism comprises a rack, a middle unlocking assembly, a left door leaf bearing assembly and a right door leaf bearing assembly; the left door leaf bearing assembly and the right door leaf bearing assembly are arranged in a bilateral symmetry mode and each comprise a lead screw rotationally installed on the rack; a movable sleeve is in threaded connection with each lead screw; a first connecting sleeve is rotationally installed on the peripheral side of each movable sleeve; the end of each first connecting sleeve is rotationally connected with a bent connecting piece through a rotary shaft; and the other end of each bent connecting piece is rotationally connected with one end of a fixing piece through a rotary shaft. According to the sliding plug door bearing driving mechanism, the lead screws and a dead point passing locking structure are used in cooperation, transmission lubrication-free is achieved, and the later maintenance cost can be reduced; the middle unlocking assembly can improve the unlocking efficiency of a door system under the emergency condition; and meanwhile, the sliding plug door bearing driving mechanism is simple in structure, the overall weight of the bearing driving mechanism is reduced, space is saved, and the manufacturing and later maintenance cost is reduced.
本发明公开了一种城轨车辆用塞拉门承载驱动机构，包括机架、中间解锁组件、左门扇承载组件和右门扇承载组件，所述左门扇承载组件和右门扇承载组件呈左右对称设置，两者均包括转动安装在机架上的丝杠，所述丝杠上螺纹连接有移动套，所述移动套的外周侧转动安装有第一连接套，所述第一连接套的端部通过转轴与弯型连接件转动连接，所述弯型连接件的另一端通过转轴与固定件的一端转动连接。本发明将丝杠与过死点锁闭结构配合使用，实现了传动免润滑，可降低后期维护成本；中间解锁组件能提高紧急情况下，门系统的解锁效率，同时其结构简单，降低了承载驱动机构整体的重量，节约了空间也降低制造和后期的维护成本。
