ABSTRACT:
The invention relates to an energy dissipation device (100) for a multi-member vehicle, a rail-mounted vehicle in particular, comprising a first end plate (10), a second end plate (20) and an energy dissipation element (30) in the form of a hollow body extending in the longitudinal direction (L) of the energy dissipation device (100) and arranged between the first and the second end plate (10, 20), whereby to prescribe the formation of folds for the energy dissipation element (30) upon activation of the energy dissipation device (100), said energy dissipation element (30) comprises a response trigger in the form of a fold/bulge area (33, 33′) extending peripherally at least partly around the periphery of the hollow body. In order to ensure that the energy dissipation device (100) can be utilized to transfer both compressive forces as well as tractive forces, the invention provides for the energy dissipation device (100) to comprise at least one tractive force-transferring element (31) which connects the first end plate (10) to the second end plate (20) and is designed to transfer tractive forces in the longitudinal direction (L) of the energy dissipation device (100), whereby the line of action (W2) for the tractive force transferred over the at least one tractive force-transferring element (31) runs completely through the interior of said tractive force-transferring element (31).
