Definitions

  • the invention relates to a support device for superstructures mounted on rail-bound freight wagons according to the preamble of claim 1.
  • a support device for containers on the base of a rail freight wagon which holds the container at both ends in end saddles arranged transversely to the longitudinal direction of the rail freight wagon and can be moved longitudinally with respect to the base, the container being suitable in the transverse direction over the end saddles Holding elements, e.g. B. straps is held on the base.
  • Holding elements e.g. B. straps is held on the base.
  • a container-side stop piece is attached, which is assigned to an abutment on the base side.
  • Each stop piece connected to the container is forcibly guided longitudinally displaceably for movements in the direction of the respectively assigned end of the base frame with respect to the respectively assigned abutment, such that forces and energies from an impact initiation at one end of the base frame via the base frame and the abutment at the end facing away from the shock of the undercarriage are introduced into the associated stop piece of the container at the end facing away from the impact device into the container.
  • the connection point between the body and the base frame is relieved when high forces are introduced into the base frame, in particular in the event of buffer impacts on the side of the buffer joint, and the buffer force that occurs is reduced.
  • the base frame is designed to be reversibly resilient in the longitudinal direction, with an energy absorption and a notable reduction in the buffer impact force targeted reversible bending of the support structure or parts of the support structure of the head sections and / or the middle section of the base frame.
  • the center section has two long girders arranged at a distance in the horizontal plane, which are connected by a bracing which reversibly couples the long girders to one another and forces them to bend at least in the horizontal plane transverse to the longitudinal direction of the underframe.
  • the invention is therefore based on the object of designing the generic support device in such a way that the energy absorption capacity of the elements of a supporting device supporting the structure in the longitudinal direction against the underframe is further increased, the resilience of the structure against the underframe is improved after the buffer joint and that stiffening elements in the end areas of the structure are largely avoided.
  • the rail freight wagons (tank wagons) shown in FIGS. 1 and 2 have a base frame 1 with two head sections 2 and a middle section 3 and a structure 4 (tank), which at the ends A and B each in a transverse saddle attached to the base frame 1 5 and by means of suitable holding elements 6 (tensioning straps) in the transverse direction on the base frame 1.
  • the longitudinal connection of the structure 4 to the underframe 1 takes place via a support device, which the structure 4 in the event of a buffer joint, i. H. a force transmission via the buffers into the underframe, against the underframe 1 for limited longitudinal movement.
  • the support device has a center saddle 7 on both sides of the structure 4, which is fixedly connected to the structure 4 in the center area of the wheelbase or bogie spacing, but not to the base frame 1.
  • a stop piece 8 is fastened to the center saddle 7 symmetrically to the center transverse plane of the body, which is attached to a frame side Abutment 9 is assigned.
  • the pairing abutment 9 / stop piece 8 is designed and arranged such that the stop piece 8 is fixed by the abutment 9 against displacements (relative movements) in the direction of the transverse central plane of the base frame 1, in the direction of the respectively assigned end A or B of the base frame 1 is held in the abutment 9 but longitudinally displaceable.
  • a tension member 10 On each abutment 9 a tension member 10 (z. B.
  • tension rod or beam, pre-tensioned cable is attached, which extends from the center saddle 7 to the associated end A or B of the base 1 and is fixed there.
  • the tension member 10 is under tensile load by stretching in the elastic range with good resilience, i. H. characterized by high restoring forces.
  • the support device has at least one tension member 10 per assigned head section 2, but expediently four tension members 10, which are arranged such that two opposing and thus each head section 2 of the underframe 1 are assigned two equivalent tension members 10 in a symmetrical arrangement.
  • the tension members 10 are formed in the exemplary embodiment as an outer longitudinal member, which extends from the head member 11 of the head section 2 via the main cross member 12 in the plane of the base frame 1 to the center saddle 7 and there engage the abutment 9 attached to the tension member 10 on the abutment piece 8. This provides a continuous edge delimitation that is desirable for security reasons.
  • the abutment 9 can also be designed as an elongated hole bearing and the stop piece 8 as a bolt.
  • the support device when subjected to an impact impact or buffer impact is explained below.
  • the impact energy is initially reduced by the buffers in the power flow - as a rule four buffers are involved in the impact - within the limits of their maximum buffer work. Since the structure 4 on the side A of the impact introduction in the direction of impact is not fixed with the abutment piece 8 in the base-side abutment 9, the buffer impact is passed through the base frame 1, with a further part of the impact energy depending on the design of the spring constant and the Damping property of the base frame 1 is reduced in the base frame 1. The now remaining impact force or impact energy is passed at the end B of the underframe 1 into the tension member 10 (um) and guided to the center saddle 7 and transferred there via the abutment 9 to the stop piece 8 on the container side. A reduction of the impact energy in the buffers, in the base frame 1 and in the tension members 10 assigned to the end B is thus achieved before force is introduced into the connection point between the base frame 1 and the body 4 on the center saddle 7.
  • the tension members 10 are effective only in one direction, namely for tensile forces from a force introduction from the end B of the base frame 1 facing away from the impact.
  • the tension members 10 assigned to the end A are not loaded when an impact is introduced at the end A of the base frame 1 and are at the force input not involved in building 4.
  • each base-side abutment 9 is arranged in the area of the head section 2 and assigned to a body-side stop piece 8, which is fixed by the abutment 9 in the direction of the transverse median plane of the freight wagon.
  • the stop piece 8 is attached to the end of the tension member 10.
  • the tension member 10 extends from the head section 2 from the stop piece 8 to the center saddle 7 and is fastened there.
  • the tension member 10 can also be designed as a continuous component, the z. B. is arranged as an outer long beam between the head sections.
  • tension members 10 are thus arranged between the structure 4 and the base frame 1, either between the base-side abutments 9 in the area of the center saddle 7 and their support at the associated end A, B of the base frame 1 or between the body-side stop pieces 8 at the end of the carriage A, B and the center saddle 7 are attached.
  • a buffer impact is diverted to the tension member 10 on the side of the base frame 1 facing away from the impact, is guided to the center saddle 7 with a reduction in impact energy and is introduced into the structure 4 from there.
  • connection of the tension member 10 between the center saddle 7 and stop piece 8 in the second exemplary embodiment corresponds functionally to the connection from the first exemplary embodiment when the elements are assigned functionally.
  • the length of the tension member 10 can be set to any intermediate length starting from the area on the center saddle 7 to the end A, B of the base frame 1. When using intermediate lengths, however, the contribution of the base frame 1 and the tension member 10 as an energy dissipation element is lower.
