Definitions

  • the invention relates to a device for storing rails of a track system for rail vehicles with a bearing plate and a bearing bed, wherein the bearing plate and the bearing bed, with the interposition of at least regionally arranged elastic elements, are supported by an interlocking profile running in the longitudinal direction of the rail and the flanks running on both sides of each rail in the longitudinal direction of the rail has, of which on both sides of each rail at least one flank with a perpendicular to the plane of the track system includes an acute angle open to the rail.
  • bearing devices which consist of a bearing plate and a bearing bed, a rail being fastened to the bearing plate and elastic elements being arranged between the bearing plate and the bearing bed.
  • a device for storing rails is shown, for example, in DE-OS 30 30 936, in which the rail is fastened to a bearing plate, which is supported against a bearing bed by means of profiling with the interposition of elastic elements.
  • the cross section of the profiling is essentially trapezoidal. This means that the elastic elements are arranged at an angle to each other and thus form an angle that is open towards the top of the rail.
  • the elastic elements closer to the center of the track system form a smaller angle with a perpendicular to the plane of the track system than the elastic elements arranged on the outside of the track system.
  • This known device has the disadvantage that, depending on the direction of loading, the bearing plate can tilt either towards the center or towards the outside of the track system into an inclined position relative to the bearing bed. An inclination of the bearing plate towards the outside of the track system results in a substantially horizontal offset of the rail head to the outside. This results in an undesirable widening of the track, which, in addition to increased wear and tear in the event of a rail breakage occurring in a curve section of the track systems, can lead to derailment of the rail vehicle. Managers can no longer be accepted.
  • Track narrowing in track systems cause high wear in the area of the wheel flanges and in the area of the side flanks of the rail heads as well as high rolling resistance and noise.
  • the invention has for its object to provide a device for storing rails, which ensures the maintenance of the track regardless of the load even in curve sections.
  • a device for storing rails of a track system for rail vehicles which has the features stated in the characterizing part of patent claim 1.
  • the flanks arranged on both sides of the rail are inclined such that the angles which they enclose with the vertical are opened approximately in the direction of the center of the track system, the angle which the inclined flank closer to the center of the track system includes with the vertical being smaller than the angle that the inclined flank makes with the vertical on the outside of the rail facing away from the center of the track system.
  • each inclined flank is assigned a second flank, the elastic elements being arranged in the region of both flanks between the bearing plate and the bed.
  • the rail with the bearing plate can pivot about a virtual pole, this pole for each rail on the outside of the track system, approximately at the height of the rail head lies.
  • bearing elements such as slide bearings, rollers or balls, which are each arranged between the flanks of the profiling of the bearing plate and the bearing bed.
  • the elastic elements arranged between the bearing plate and the bearing bed are compressed to different extents by the stress that occurs.
  • the second flanks assigned to the inclined flanks expediently run essentially perpendicular to the plane of the track systems. These flanks essentially have the task of absorbing the transverse forces which occur, which essentially arise from the managers of the rail vehicles when driving on curve sections.
  • elastic elements are arranged at least in part of the flanks between the bearing plate and the bearing bed.
  • the elastic elements have the property of being able to absorb transverse forces more elastically than compressive forces.
  • the elastic elements can also only be arranged such that they ensure that the bearing plate is pushed back into the normal position.
  • the elastic elements are preferably made of synthetic rubber, natural rubber, cork, polyurethane or polysulfide. These materials have the property of being elastic against transverse forces and of being more stable in their form against compressive forces.
  • the elastic elements expediently have a rectangular, square, trapezoidal, round or polygonal cross section. Depending on the type of profiling on the bearing plate and on the bed, the elastic elements can have the cross-sections mentioned above.
  • the profiling is advantageously formed by at least two tooth-shaped strips on the bearing plate and corresponding recesses on the bearing bed.
  • the profiling designed as tooth-shaped strips extends parallel to the longitudinal axis of the rail.
  • a device for storing rails with a profile formed in this way and having two tooth-shaped strips is very stable in relation to the forces which occur, since the tooth-shaped strips are arranged essentially far apart in the area of the outside of the bearing plate or the bearing bed.
  • the rail fastened on the opposite side of the bearing plate is thus essentially between the two toothed strips.
  • a plurality of tooth-shaped strips distributed parallel to one another and distributed over the width of the bearing plate and bearing bed measured at right angles to the longitudinal axis of the rail can also be provided.
  • FIG. 1 and 2 show the device with a rail 1, which has a rail base 1a, a rail head 1d, with an end face 1b and side flanks 1c.
  • the rail 1 is fastened on a bearing plate 3 by means of fastening elements 3a.
  • the horizontal, lateral displacement or the lateral guidance of the rail 1 is ensured with the aid of projections 3b which protrude from the top of the bearing plate 3.
  • the bearing plate 3 and the bearing bed 6 have an interlocking profile, which in the example shown has two tooth-shaped strips 4, 5 on the bearing plate 3 and two recesses 7, 8 in the bearing bed 6.
  • the tooth-shaped strips 4, 5 protrude with the interposition of elastic elements 9a, 9b, 9c, 9d into the recesses 7, 8 of the bearing bed 6, which is fastened on a solid base U, for example a rail sleeper, by means of fastening elements (not shown).
  • the elastic elements 9a, 9b, 9c, 9d keep the bearing plate 3 and the bearing bed 6 at the original distance from one another.
  • the tooth-shaped strips 4, 5 and the recesses 7, 8 have flanks 4a, 7a, 5a, 8a which run at an angle deviating from 90 ° to a perpendicular to the plane of the track system.
  • the flanks 4a, 7a, 5a, 8a are arranged obliquely in such a way that the different angles to the center of the track system are open and increase in angle from the inside of the rail 1 directed towards the center of the track system to the outside of the rail 1. This means that the flanks are closer to the center of the track system 4a, 7a arranged steeper with respect to a horizontal than the flanks 5a, 8a, which are further from the center of the track system.
  • the tooth-shaped bar 4 which is closer to the center of the track system is essentially more pointed than the tooth-shaped bar 5.
  • the elastic elements 9a, 9b, 9c, 9d have the property of reacting more elastically to transverse forces than to compressive forces.
  • the bearing bed 6 at least partially encompasses the bearing plate 3 with encompassing parts 6c, 6d.
  • elastic stabilizers 10 are located between the parts 6c, 6d and the bearing plate 3 connected to the bearing bed 6 and encompassing the bearing plate 3.
  • the bearing plate 3 is designed such that it projects beyond the bearing bed 6 in the longitudinal direction of the rails 1, the projecting part of the bearing plate 3 extending vertically downward and the bearing bed 6 partially overlapped.
  • Elastic elements are additionally arranged between the bearing plate 3 and the bearing bed 6, which form the corresponding resistance to push-through. The overlap of the bearing bed 6 by the bearing plate 3 in the longitudinal direction of the rails 1 is not shown in.
  • FIG. 2 shows the device, wherein a wheel 2 of a rail vehicle (not shown in the drawing) rests on the end face 1b of the rail 1 and touches the side flank 1c of the rail head 1d with the wheel flange 2a. Occurring horizontal loads P H and vertical loads P V as well as the proportional weight, which results from the weight of the rail vehicle, and the weight of the Payload composed, are transferred from the wheel 2 to the rail head 1d of the rail 1.
  • the stabilizers 10 which are closer to the center of the track system are relieved when a load occurs.
  • the essentially horizontally acting loads P H which are caused by the managers of the rail vehicles when driving on curve sections, are absorbed by the elastic elements 9b, 9d arranged parallel to the vertical.
  • the elastic elements 9b, 9d are supported on the flanks 4b, 7b, 5b, 8b.
