Rail vehicle having central buffer coupling

A rail vehicle, comprising:

• a carriage body;
• a central buffer coupling having, as elements, a coupling head, a bar-shaped coupling shaft and a spring mechanism, wherein said coupling head is configured for connection to further a coupling head of a further rail vehicle, wherein said coupling head is connected to a first side of said bar-shaped coupling shaft and in which a second side of said bar-shaped coupling shaft dips into said spring mechanism and is mounted and fastened therein such that, in an operative mode of the rail vehicle, impact forces or tensile forces acting on said coupling head are elastically absorbed by said spring mechanism, which is connected to said carriage body of the rail vehicle, and the impact forces and the tensile forces are transmitted to said carriage body;
• a support coupled to said bar-shaped coupling shaft and connected to said carriage body, said support configured to vertically support said bar-shaped coupling shaft in order to downwardly support said bar-shaped coupling shaft in a resilient manner in a vertical direction, said support further configured to bear a dead weight of said elements of said central buffer coupling in order to implement a horizontal orientation of said central buffer coupling in the operative mode of the rail vehicle;
• and
• a collision element disposed between said support and said carriage body and is connected both to said support and to said carriage body, said collision element having a deformation region configured such that kinetic energy, which is transmitted via said bar-shaped coupling shaft and via said support to said collision element in an event of a collision, non-reversibly deforms said deformation region in a predefined manner.
