The invention discloses an urban rail train traction device capable of recycling braking energy, and relates to the technical field of train traction, the urban rail train traction device comprises a mounting hanger, the middle part of the mounting hanger is rotatably connected with a buffer part, and the buffer part is provided with a coupling part in the direction away from the mounting hanger. By utilizing the friction temperature rise between the crushing pipe body and the sliding sleeve, the memory metal rod is heated to expand, the ball plug automatically opens the oil outlet pipe, and the outer wall of the crushing pipe body can be automatically and uniformly coated with lubricating oil in cooperation with the telescopic sliding of the sliding sleeve, so that the friction between the crushing pipe body and the sliding sleeve can be effectively reduced, the friction loss of the crushing pipe body is reduced, and the service life of the crushing pipe body is prolonged. Meanwhile, friction energy consumption of train operation is reduced, consumption of stored energy is reduced, more energy can be saved for other electrical systems of the train, and sufficient recycling of braking energy is facilitated.
本发明公开了一种制动能源再利用的城市轨道列车牵引装置,涉及列车牵引技术领域,包括安装吊挂件,安装吊挂件的中部转动连接有缓冲件,缓冲件远离安装吊挂件的方向安装有连挂件,通过自动润滑机构的设置,利用压溃管本体与滑套管之间摩擦升温,使记忆金属杆受热膨胀,自动让球塞开启出油管,配合滑套管的伸缩滑动,使得压溃管本体外壁可被自动且均匀地涂抹润滑油,能有效降低压溃管本体与滑套管的摩擦,减少了压溃管本体的摩擦损耗,以便增强其使用寿命,避免车钩意外断裂,同时,减少列车运行的摩擦能耗还有利于降低储备能量的消耗,节省的能量可更多地供车辆其他电气系统使用,有利于制动能源的充分再利用。
