A collision energy absorbing device of a railcar includes: an outside plate constituting an outer tube including an axis extending in a car longitudinal direction; and at least one partition plate extending in the car longitudinal direction in an internal space surrounded by the outside plate, the at least one partition plate fixed to the outside plate and dividing the internal space. An outer shape of the outer tube is a shape that is symmetrical with respect to a virtual horizontal surface including the axis, and the at least one partition plate includes a missing portion in the internal space.

An energy-absorbing device, in particular for a rail-car, extends along an axis and has an attachment member, which can be connected to a fixed structure, an impact member, designed to withstand an impact, and an energy-absorbing member, constituted by a first tube and a second tube, which are coaxial and are made of composite material in order to collapse and hence absorb energy in the event of impact; the first tube is fixed to the attachment member, whereas the second tube is fixed to the impact member and is axially slidable, during impact, guided by the first tube; the radial thickness of the two tubes decreases along the axis, towards their free ends; in a non-collapsed resting condition, the axial gaps present between the two free ends and the attachment and impact members are substantially the same so that the two tubes start to collapse simultaneously in the event of impact.

Disclosed is a telescopic type collision energy absorption device for a rail vehicle, which includes two sets of mechanisms functioned individually. The two sets of mechanisms are mounted respectively on either side of end portion of the vehicle. Each set of the mechanism includes an anti-climber, an energy absorption circular tube, pull rings, cutters, cutter fixing blocks, a mounting base, a cutter base, a guide cartridge, a double-acting type air cylinder, a base, bolts, torsional springs, pins, locating slots, a double-acting type solenoid valve, a controller and air storage tank. When the energy absorption device is in a non-operating state, the double-acting type air cylinder is in a state of tension where it pulls the energy absorption circular tube in such a way that the energy absorption circular tube is retracted into the interior of the guide cartridge, the cutters are pressed against the outer wall of the energy absorption circular tube. Before a collision of the vehicle, the double-acting type air cylinder under the effect of the high-pressure air pushes the second tube in such a way that the second tube is ejected outwards, the cutters are pressed against the locating slots of the energy absorption circular tube under the effect of spring force. The cutters cut the energy absorption structure and absorb the energy when the energy absorption circular tube is subjected to an external force and retracts towards the interior of the guide cartridge.

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.

A rail vehicle has a bogie which rolls on a track in a direction of travel, a vehicle structure which is supported on the bogie, a rigid carrying structure which is arranged on the end side of the rail vehicle, and an end-side coupling opening through which a coupling extends for coupling further rail vehicles. A coupling securing device secures the coupling to the rail vehicle. The coupling securing device has reversible securing elements which permit a reversible lifting movement counter to the direction of travel to such an extent that the coupling is retracted completely into the supporting structure. As a result of the retraction of the coupling into the cage-like carrying structure it no longer influences the crash behavior.

A deformable element includes a profiled tube having a rectangular cross-section, and a plate which closes the profiled tube at one end, where a bracket is fastened between opposite sides of the profiled tube at the end of the profiled tube that is closed by the plate.
