Abstract
A rail vehicle has a central buffer coupling with a coupling head, a rod-shaped coupling shaft and a spring mechanism. The coupling head connects to a coupling head of another rail vehicle and is connected to the coupling shaft. The shaft is inserted into the spring mechanism and is mounted and fastened therein such that, during operation of the rail vehicle, impact forces or tensile forces acting on the coupling head are resiliently absorbed by the spring mechanism and transferred to a wagon body. A support is coupled to the coupling shaft and is connected to the wagon body. A collision element is arranged between the support and the wagon body. The collision element has a deformation region configured such that kinetic energy, transferred to the collision element via the coupling shaft and via the coupled support due to a collision, irreversibly deforms the deformation region in a predetermined manner.
