Definitions

  • the invention relates to a base frame for rail-bound freight wagons, in particular tank wagons and closed bulk goods wagons, according to the preamble of claim 1.
  • Every rail-bound freight wagon is connected to a chassis for transport purposes. This applies to freight wagons with fixed bodies and container wagons with detachable bodies as well as for tank wagons and closed bulk goods wagons.
  • the application of the invention relates only to the freight car with a base.
  • the known tank wagons can be divided into two construction concepts, tank wagons without a base and tank wagons with a base.
  • the following discussion of the state of the art takes into account the state of the art of the underframe-free tank wagons in the first section for the sake of incorporating the technological environment.
  • the boiler In the tank wagons without an underframe, the boiler is designed to be so stable that it can absorb the operationally occurring forces and tensions, in particular from shock loads, without undue deformation. With this design, a reduction in weight or improved adaptability of the chassis arranged on the boiler to the track conditions can be achieved for certain applications.
  • the connection of the assemblies carrying the train and push device and the bogies to the boiler is problematic, whereby the introduction and reduction of the forces and energy from the buffer joint and in the event of lifting is ensured without excess voltage and inadmissible deformations within the construction got to.
  • a base frame for rail-bound tank wagons of conventional design with two continuous middle long beams is known as a middle section, at each end of which a head section with outer long beams and cross beams connecting them is arranged.
  • the boiler is supported at its ends on the one hand in transverse saddles arranged transversely to the longitudinal direction of the boiler on the underframe and on the other hand connected to the underframe via lateral saddle support bars which absorb the acceleration forces in the longitudinal direction of the wagon.
  • the boiler is in the usual way via side saddle rails, which absorb the forces from the deceleration and acceleration of the tank car, and cross saddles, the static Take up the weight load and the forces occurring transversely to the longitudinal direction of the wagon, connected to the underframe.
  • the tank wagon is through this rigid connection between the boiler and the base frame thus also relatively torsion-resistant.
  • the connection points between the boiler and the base frame must also absorb the loads caused by the acceleration and weight forces.
  • the invention has for its object to provide a base frame for freight wagons, especially for tank wagons and closed bulk goods wagons, in such a way that the connection points between the base frame and the body are relieved in the event of buffer impacts on the side of the buffer joint and the buffer forces that occur are reduced.
  • the underframe 1 is to be designed for the loads in the longitudinal direction, in particular from buffer joints.
  • a rail-bound freight wagon has a structure 15 and a base frame 1, which is formed by two head sections 2 and a middle section 3.
  • the middle section 3 is connected at its two ends A, B to a head section 2.
  • the head section 2 consists of a side cross member 5 receiving the side buffers 4, the outer long members 6 and the main cross member 7.
  • the cross members 5, 7 arranged in the vehicle transverse direction, at least one cross member 5, 7 is reversibly flexibly connected to the outer long members 6 about a vertical axis. Arrangements with one or more transverse beams 5, 7 which are flexible about a vertical axis can be formed.
  • the outer long beams 6 of the head section 2 can be designed to be reversibly flexible.
  • the middle section 3 consists of two long beams 8 which are arranged at a distance in the horizontal plane and which are connected by a bracing 9.
  • the strut bandage 9 is designed and arranged in such a way that it couples the long beams 8 to one another in a flexible manner and forces them to undergo reversible deformations, at least in the horizontal plane, in particular to bending deformations transverse to the longitudinal direction of the underframe.
  • the bracing 9 is designed as a horizontal bracing 9 aligned as a horizontal plane or as a spatial bracing 9 and has diagonal braces 10 aligned at an angle to the long beams 8, which are at an angle smaller or greater than 90 ° with respect to the longitudinal direction with respect to the horizontal plane the long beam 8 connects. Furthermore, the strut bandage 9 has support struts 11 which are oriented transversely to the long beams 8 and connect the long beams 8 at right angles to the horizontal plane. The diagonal struts 10 and support struts 11 are arranged in an at least partially repeating sequence within the strut assembly 9, wherein individual fields arise.
  • the diagonal struts 10 of the strut assembly 9 follow one another with respect to the arrangement in the longitudinal direction of the underframe 1 at least in regions with an opposite angle. At least in some areas within the underframe 1, at least one diagonal strut 10 connecting the long members 8 is provided between two support struts 11 connecting the long members 8, the diagonal struts 10 arranged immediately on both sides of a support strut 11 being at least partially within the underframe 1 with an opposite angle with respect to the longitudinal direction a long beam 8 are arranged.
  • the diagonal strut (s) 10 and the support strut (s) 11 assigned to them expediently each engage in a common node 12 on the long beam 8.
  • At least one diagonal strut 10 and an adjacent support strut 11 are attached to the long beam 8 in the common node 12.
  • the diagonal struts 10 and the support struts 11 within the strut assembly 9 are connected to the long girders 8 in such a way that from each junction 12 of a long girder 8 there is a support strut 11 aligned transversely to the long girders 8 and at least one, but preferably two, diagonally oriented diagonal struts 10 have adjacent long beams 8 and are attached to this.
  • the support strut 11 is attached at its other end to the adjacent long beam 8 in a support point 13.
  • the or selected nodes 12 and / or support points 13 can be designed as joints, both functional joints and material-elastic joints being executable.
  • two support struts 11 aligned transversely to the long beams 8 can follow one another directly, thus creating a space in the base frame 1 for the outlet fittings.
  • Each head section 2 has a saddle 14 for connecting the structure 15 to the underframe 1, such that each saddle 14a, 14b defines the end A, B of the structure 15 supported by it in the direction of the transverse median plane of the underframe 1, the ends A , B of the structure 15 in the direction of the respectively associated end A, B of the base frame 1 are held longitudinally displaceably against the base frame 1.
  • the forces from a buffer joint are thus introduced via the base frame 1 into the end of the structure 15 facing away from the buffer joint.
  • the structure 15 has at its end A an abutment piece 16a on the body side, to which an abutment-side abutment 17a is assigned and at its end B an abutment piece 16b on the abutment side, to which an abutment-side abutment 17b is associated.
  • the stop pieces 16a, 16b and the abutments 17a, 17b are arranged above the level of the force introduction, which is at the level of the side buffers.
  • an arrangement of the stop pieces 16a, 16b and the abutment 17a, 17b respectively assigned to them can be arranged in the plane of the force application, i. H. in the level of the page buffer 4.
  • the invention is explained below when it is subjected to an impact impact.
  • the impact energy is first of all reduced by the side buffers 4 in the power flow, as a rule four side buffers 4 are involved in the impact, within the limits of which the maximum total buffer work is reduced.
  • the impact force or energy from the buffer impact becomes exhausted Buffer stroke passed through the underframe 1, a further part of the impact energy being absorbed or reduced in the underframe 1 essentially by deformation work, but also by friction and heat, etc., depending on the design, the spring constant and the damping property of the underframe 1 .
  • the base frame 1 according to the invention as a bending structure which is flexible and resilient in the longitudinal direction, considerable portions of the impact energy are absorbed and impact force is reduced.
  • the energy absorption and the reduction of the impact force take place essentially by deliberately reversible bending of the structure or of parts of the structure of the head sections 2 (cross beams 5, 7; outer long beams 6 and possibly further beams) and / or the middle section 3 (long beams 8 and possibly further ones) Carrier) of the underframe 1.
  • the longwall brace 9 connects and couples the long girders 8 of the middle section 3 in such a flexible manner that they are forced to targeted, reversible bending deformations transverse to the longitudinal direction of the underframe 1.
  • the elongated beam 8 is bent outwards at the junction 12 by a certain bending path ⁇ s in the event of an impact impact.
  • the opposite long beam 8 is coupled with the support strut 11 in the support point 13, the latter is displaced inwards by the same distance ⁇ s (FIG. 2).
  • a base frame 1 is formed with a plurality of flexible cross members 5, 7 and the strut assembly 9 is arranged axially symmetrically.
  • Fig. 5 also shows schematically an embodiment of a face brace 9 in axial symmetry.
  • FIG. 1 is, like a further exemplary embodiment according to FIG. 6, of central symmetry.
