| 摘要 |
The invention concerns a shock absorbing device, particularly between a mobi le gear (1) and an obstacle (2) or between two mobile gears consisting of an energy absorbing structure (3) capable of being extended by actuators (4) controlled to operate. Said device is characterised in that the extensible structure (3) is made up of compressible beams (6) which, when the structure (3) is in extended position, absorb by their irreversible axial compression the energy generated by an impact produced along a specific direction (D), said compressible beams (6) being linked to one another and/or to rigid guiding elements (7) by linkages (8, 9, 11) allowing a rotating and/or translating movement of said beams (6) when the structure (3) is being extended.
