Urban rail vehicle door leaf bearing part structure
The invention belongs to the technical field of rail transit, and discloses an urban rail vehicle door leaf bearing part structure which comprises a rack and a door carrying frame connected to the rack through a moving pair, and the door carrying frame can be driven by the moving pair to move; the sliding pair comprises a lead screw and a nut pair hinge assembly, the lead screw is connected to the machine frame through a support, the end of the lead screw is connected with an end unlocking piece, the nut pair hinge assembly is connected to the lead screw, the door carrying frame is installed on the nut pair hinge assembly, and a guide assembly is arranged between the door carrying frame and the machine frame. The lead screw and the end unlocking piece structure are used in a matched mode, transmission is free of lubrication, locking is reliable, unlocking is passive, and the reliability of a system can be improved; the end unlocking piece can improve the unlocking reliability of the door system under the emergency condition, meanwhile, the structure is simple, the overall weight of the bearing driving mechanism is reduced, the space is saved, and the manufacturing and later maintenance cost is reduced.
本发明属于轨道交通技术领域，公开了一种城轨车辆门扇承载部件结构，包括机架、以及通过移动副连接在所述机架上的携门架，所述携门架在所述移动副的带动下可进行移动；所述移动副包括丝杠和螺母副铰链组件，所述丝杠通过支架连接在所述机架上，所述丝杠的端部连接有端部解锁件，所述螺母副铰链组件连接在所述丝杠上，且携门架安装在螺母副铰链组件上，所述携门架与所述机架之间设有导向组件。本发明将丝杠与端部解锁件结构配合使用，实现了传动免润滑，锁闭可靠，解锁无源，可提高系统的可靠性；端部解锁件能提高紧急情况下，门系统的解锁可靠性，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。
