Abstract

The invention provides a rail vehicle. Among them, the rail vehicle includes: an underframe assembly, including a primary energy-absorbing structure and an underframe side beam, the primary energy-absorbing structure is connected to the underframe side beam of the rail vehicle, and the primary energy-absorbing structure has at least two Energy cavity; side wall assembly, the lower end of which is connected to the underframe assembly; roof assembly, the upper end of the side wall assembly is connected to the roof assembly; vehicle end assembly, including the end energy-absorbing structure, and the lower end of the end energy-absorbing structure It is connected with the primary energy-absorbing structure, and the upper end of the end energy-absorbing structure is connected with the roof assembly. Applying the technical solution of the present invention, the primary energy-absorbing structure on the underframe assembly, the roof assembly, and the end energy-absorbing structure installed between the roof assembly and the primary energy-absorbing structure form the entire end of the vehicle body structure The energy-absorbing structure does not need to add independent energy-absorbing structural elements; the invention improves the collision energy-absorbing performance of the vehicle without increasing the external size of the vehicle body structure.

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...
