of the front apron 2 it prevents in permissibly high impact loading being transferred to the structure of the shell 16 in the event of a crash fig5 a shows the no loading case the crash resistant front apron 2 essentially consists of a support apparatus 8 comprising a first support part 9 to which a front apron 23 is attached and a second support part 10 which is attached to the shell 16 or to the rail vehicle chassis respectively between the first support part 9 and the second support part 10 is arranged a friction coupling release mechanism 11 in fig5 b the surface force acting in the event of a crash on the front apron cover 23 is indicated by an arrow 21 a torque around the axis 13 acts on the first support part 9 when the frictional adhesion in the friction coupling release mechanism 11 is overcome the first support part 9 twists in relation to the solidly mounted second support part 10 as outlined in fig5 c in the event of a crash the first support part 9 along with the front apron cover 23 falls off this means that no connection exists any longer between the application of force 21 to the front apron covered 23 and the shell 16 and impermissibly high loading of the anchoring of the support apparatus 8 in the shell 16 is avoided in the diagram depicted in fig6 a and 6 b the friction coupling flange 30 embodied on the first support part 9 or on the second support part 10 respectively is shown as a detail in a side view and in an axial overhead view.
