Abstract
The present invention provides a rail vehicle. The rail vehicle includes: an underframe assembly, a side wall assembly, a vehicle roof assembly, and a vehicle end assembly. The underframe assembly includes a primary energy absorption structure and an underframe edge beam which are connected. The primary energy absorption structure has at least two energy absorbing cavities that are set at interval. The lower end of the side wall assembly is connected with the underframe assembly. The upper end of the side wall assembly is connected with the vehicle roof assembly. The vehicle end assembly includes an end energy absorption structure whose lower end is connected with the primary energy absorption structure, and upper end is connected with the vehicle roof assembly. By using the technical solution of the present invention, that is, the primary energy absorption structure of the underframe assembly, the vehicle roof assembly, and the end energy absorption structure which is installed between the vehicle roof assembly and the primary energy absorption structure form the overall energy absorbing structure at the end of the vehicle body structure, there is no need to add an independent ene…
