ABSTRACT:
An energy dissipation device (1) is provided for a car body of a multi-element vehicle in particular a rail vehicle, the energy dissipation device (1) having a damping unit (10) having a regeneratively implemented damping element (11) for damping traction and impact forces occurring in normal travel operation and an energy dissipation unit (20) having a destructively implemented energy dissipation element (21), and the energy dissipation element (21) being designed to respond after a previously determinable critical impact force is exceeded and to transmit at least a part of the impact forces transmitted via the energy dissipation device (1) into heat and deformation work by plastic deformation and thus dissipate them. In order that the energy dissipation device (1) only requires a small installation space, the damping unit (10) is integrated in the energy dissipation unit (20) in such a way that during a transmission of impact forces, the force flux runs through both the damping unit (10) and also the energy dissipation element (20).
