Abstract (en)
[origin: EP2072370A1] The damper (10) between rail wagons, to take up pull and push forces, has a regenerative damping element (11) to absorb forces under normal travel conditions. It also has an energy assimilation unit (20) with a destructive element (21) which converts energy above a critical push force into heat and distortion forces. The damper has two pressure plates (12,13) with the damping element between them. The distorting tube section (23) has at least one guide surface (24) for the interaction between the plates moving the energy assimilation assembly (1) in a longitudinal direction (L).
