Rail vehicle having a coupling arranged in the front region thereof
A rail vehicle includes a coupling disposed centrally in a front region of the rail vehicle. The coupling is mounted in a transversely extended crossmember, so that forces acting on the coupling are introduced through the crossmember into abutments which are supported on a front side of a car body of the rail vehicle. The crossmember is connected through at least one elastic energy absorption configuration to one of the abutments.
1. A rail vehicle, comprising:
a rail vehicle body having a front and a front end;
abutments supported on said front end;
a transversely extended crossmember;
at least one elastic energy-absorption configuration connecting said crossmember to one of said abutments;
a coupling disposed centrally in a vicinity of said front and mounted in said crossmember, for introducing forces acting on said coupling through said crossmember and into said abutments; and
two connecting rods each being extended in a longitudinal direction of the rail vehicle and being fixed to a respective one of said abutments;
said elastic energy-absorption configurations each being disposed on a respective one of said connecting rods, said elastic energy-absorption configurations each including an energy absorption element, and said respective one of said connecting rods extending through said energy absorption element;
said crossmember having retaining portions with openings formed therein;
said connecting rods each passing through a respective one of said openings; and
said elastic energy-absorption configurations being constructed for lateral abutment against said retaining portions.
2. The rail vehicle according to claim 1 , wherein said energy-absorption configuration includes energy-absorption elements being disposed and constructed in part for tensile stressing and in part for compressive stressing of said coupling.
3. The rail vehicle according to claim 1 , wherein said at least one elastic energy-absorption configuration includes two elastic energy-absorption configurations each being disposed on a respective transverse side of the rail vehicle, in a state in which said elastic energy-absorption configurations are offset horizontally relative to said coupling.
4. The rail vehicle according to claim 1 , wherein said crossmember is guided at least one of vertically or laterally relative to said abutments by said connecting rods.
5. The rail vehicle according to claim 1 , wherein said crossmember has an inward end portion relative to the rail vehicle, and stops guide said inward end portion on said front of the rail vehicle or said body.
6. The rail vehicle according to claim 1 , wherein said abutments are constructed as deformable crumple elements for absorbing collision energy.
7. The rail vehicle according to claim 1 , wherein said abutments are interchangeably fastened on said front of the rail vehicle.
8. The rail vehicle according to claim 1 , wherein said front of the rail vehicle is constructed as a specifically deformable crumple zone for absorbing collision energy.
9. The rail vehicle according to claim 8 , wherein said front of the rail vehicle is interchangeably fastened on said body of the rail vehicle.
10. The rail vehicle according to claim 1 , wherein said coupling includes a coupling rod, and energy absorption elements for reversible or irreversible energy absorption or force-limiting are disposed in said coupling rod.
11. The rail vehicle according to claim 1 , wherein said coupling includes a coupling rod, and energy absorption elements for reversible or irreversible energy absorption or force-limiting are disposed between said coupling rod and said crossmember.
