Background The train through passage with the function of connecting, disconnecting and editing is a key technical device in modern urban rail transit and railway vehicles. The device not only bears the functions of flexible connection and passenger passing between carriages, but also supports quick and safe mechanical connection (connection and disconnection) during train marshalling adjustment (such as increasing and decreasing carriages). At present, most through passages for trains with the functions of connecting, disconnecting and editing are still mainly realized by manual modes, and particularly in urban rail transit systems such as subways, light rails and the like. Although full-automatic through-channel technology is under development, manual operation is still the mainstream solution due to factors such as cost, reliability, maintenance convenience, and operation habit. In the prior art, an automatic pushing structure is arranged on part of the through channels, but the problems of complex structure, unreasonable layout and the like are often caused. For example, the part of the automatic linking and unbinding through channel is used as a telescopic driving structure to drive the through channel to link or unbinding, the structure is complex, the flexibility is poor, and the part of the automatic linking and unbinding through channel is used for selectively arranging the linking and pushing structure at the top of a vehicle or in a carriage, so that interference with other vehicle structures is easy to generate. In addition, during the curved running of the vehicle, motion deflection is generated between carriages, and the through-passage is required to have the capability of adapting to the curved running of the vehicle. In the prior art, the small curve has poor passing capability after the through channel is hung.
