Crash absorber for a railborne vehicle as well as rail vehicle with a base and with a crash absorber

摘要

Crash absorber (1) for a rail vehicle, comprising at least one energy absorption unit (2 a)– with at least one plunger (3), which in an axial direction (x) has a length (l), wherein the plunger (3) in a first stamp portion (3.1), at least over a part of (l₁) its length (l), an outer cross-section (q₁) has,– with a guide element (4) the plunger (3), in which the die (3) in the axial direction (x) between a starting position and an end position is movable, the guide element (4) in a deformable guide section (4.1) an internal cross section (q₂) , the smaller than the outer cross section (q₁) of the first stamp portion (3.1) is,wherein, in the initial position of the first stamping (3.1) outside of the guide portion (4.1) is arranged and, by a movement in the axial direction (x) in the guide portion (4.1) is displaceable in such a way that the guide element (4) in the guide portion (4.1) expands,the energy absorption unit (2) a further comprising a stretchable energy absorption element (5) the guide element (4) comprising the guide section (4.1) perpendicular to the axial direction (x) at least over part of its circumference and touched on the outside,characterized in that the guide element (4), starting at the insertion end (4.12) in the axial direction (x) is at least in sections, several slots.
