The invention provides a collision energy absorbing device and a rail vehicle with the same, a first-order energy absorbing structure is provided with at least two energy absorbing cavities arranged at intervals; a second-order energy absorbing structure consists of at least two energy absorbing tubes arranged at intervals. A first ends of the energy absorbing tubes is connected with the first-order energy absorbing structure. The energy absorbing tube is a hollow structure and is provided with a first induction part. The structure of the energy absorbing tube is simple, and because the energyabsorbing tube has the first induction part, the energy absorbing tubes first deform at the position where the first induction part is arranged when the collision occurs, so that the deformation of the energy absorbing tubes is in a controllable state. Uncontrollable deformation of other parts of the rail train, which threatens the personal safety of the passengers inside the train, is avoided. Therefore, the anti-collision performance of the energy absorbing device is improved.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and a collision energy-absorbing device thereof. 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....
