摘要： 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 energy absorbing component. The present invention improves impact energy absorbing performance of the vehicle without increasing the overall dimension of the vehicle body structure.

摘要： A reusable collision energy absorption device for a rail vehicle includes an impacted rod, a damping structure including a damping plug, a guide tube and a damping elastic element, a return structure including a return piston and an elastic return element, an outer tube having a tubular structure, and an interior partitioned into a front cavity and a rear cavity through a partition plate provided with a damping hole in the form of a through hole. A portion of the damping plug is in the damping hole when the damping plug is in an initial position, and the damping plug can move in a front-rear direction when the device is impacted. A gap between a radial thickest portion of the damping plug and the damping hole allows the fluid to circulate between the front cavity and the rear cavity.

摘要： A railcar collision energy absorbing device includes: an energy absorbing element crushed in collision; and a casing extending in a car longitudinal direction so as to accommodate the energy absorbing element. One end of the casing is supported by a main structure of a railcar. The casing is constituted by a plurality of tubular bodies whose overlapping portions are coupled to each other. The casing telescopically contracts in the collision by breaking of a coupling portion between the tubular bodies.

摘要： An anti-climbing protection apparatus for a rail vehicle includes at least one buffer supported by an energy absorption element connected to a rail vehicle frame. In order to permit such a protection apparatus to be produced economically, to reliably prevent overriding and to be comparatively easy to retrofit, a bearing element is fastened to an end of the energy absorption element facing away from the vehicle frame. The bearing element supports an anti-climbing protection device at an end thereof protruding in a vertical direction from the buffer. In the event of a crash, a horizontally oriented stop, in cooperation with the front of the rail vehicle, permits an anti-climbing protection element of the anti-climbing protection device to be brought from the stop into an anti-climbing protection position extending outward over the buffer.
