Abstract: A train having a protection device with self-adaptive crashworthiness is disclosed, which relates to the technical field of safety protection of trains. The train includes multiple vehicles, a head vehicle is located at the head end of the train, and a head vehicle energy absorbing coupler mechanism is mounted at the front end of the head vehicle, each two adjacent vehicles are connected to each other by a middle vehicle energy absorbing coupler mechanism. An image acquisition mechanism and a radar detector are mounted at the head vehicle for monitoring whether there is an obstacle ahead the train, measuring distance and collision speed between the train and the obstacle, and for transmitting measured data to a processing center of the train, the processing center optimizes and adjusts impact force at the head vehicle energy absorbing coupler mechanism and the middle vehicle energy absorbing coupler mechanisms based on a collision situation.

Abstract: 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.

Abstract: An anti-derailment apparatus for a bogie of a rail vehicle of the disclosure comprises at least one mounting seat and an anti-derailment slide plate. The transverse orientation of the anti-derailment slide plate on the mounting seat and the extending length of the anti-derailment slide plate in the vertical direction meet the following requirements simultaneously: 1) making the anti-derailment slide plate located at the inside of the ground rail when the rail vehicle runs normally; 2) when at least one wheelset of the rail vehicle climbs rail, the anti-derailment slide plate acts on the ground rail to form lateral limitation points so as to limit the freedom of the rail vehicle and make it still constrained by the ground rail.
