The invention provides a track vehicle. The track vehicle comprises a chassis assembly, a side wall assembly, a vehicle roof assembly and a vehicle end assembly, wherein the chassis assembly comprisesa first-level energy absorption structure and a chassis edge beam, the first-level energy absorption structure is connected with the chassis edge beam of the track vehicle, the first-level energy absorption structure is provided with at least two energy absorption cavities formed at intervals, the lower end of the side wall assembly is connected with the chassis assembly, the upper end of the side wall assembly is connected with the vehicle roof assembly, the vehicle end assembly comprises an end energy absorption structure, the lower end of the end energy absorption structure is connected with the first-level energy absorption structure, and the upper end of the end energy absorption structure is connected with the vehicle roof assembly. By applying the track vehicle, the first-level energy absorption structure and vehicle roof assembly on the chassis assembly and the end energy absorption structure arranged between the vehicle roof assembly and the first-level energy absorption structure form an end overall energy absorption structure of a vehicle body structure, and an independent energy absorption structure element does not need to be added any longer; under the situation of not increasing the external dimension of the vehicle body structure, the collision energy absorption performance of the vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle. Background technique [0002] With the rapid development of my country's rail transit and other fields, while it is convenient for people to travel, its operation safety has attracted more and more attention. Rail transit vehicles such as subways usually carry a large number of passengers and run at a high speed. Once a collision accident occurs, it often causes relatively large casualties and property losses. Accidents such as train rear-end collisions in recent years have fully demonstrated that even with a series of active protection measures such as signal control, dispatch management and procedural management, train collision accidents cannot be completely avoided. The performance of the passive safety protection device of the ultimate guard of personnel life and property safety is particularly important. [0003] Statistics show that rail vehicles ne...
