Definitions

  • the invention relates to an elastic tension clamp according to the preamble of patent claim 1 and a rail fastening arrangement comprising such a tension clamp.
  • the elastic clamps are pressed by means to be anchored in the threshold screws on the foot of the rail, such as in the DE 32 43 895 A1 is described.
  • the tensioning clamp described therein can already be preassembled in the sleeper plant and rotated 180 ° into the mounting position for final bracing of the rail in the track from its pre-assembly position.
  • the tension clamp comprises an arcuate middle part and two legs adjoining the middle part. The arcuate middle part and the adjoining legs surround in their installed position the shaft of a sleeper screw for attachment to a threshold.
  • the elastic attachment of the rail is carried out on to the inner leg adjoining sections of the tension clamp, which on the foot Press a rail.
  • the rail fastening arrangement comprises a guide plate, which rests on each side of the rail foot on the threshold and whose surface contour is adapted to the elastic tension clamp, so that the forces coming from the rail can be introduced into the threshold.
  • Fig. 6 gives an example from the prior art again. Shown is a threshold 10, the rail channel 14 in addition to a preassembled rail fastening arrangement and one on a Angle guide plate 18 launched tension clamp 30 which is pre-assembled in the unloaded state by means of a sleeper screw 24 at the threshold, wherein the head 26 of the sleeper screw 24 rests on the tension clamp 30.
  • the invention has for its object to provide an elastic clamp and a rail fastening arrangement using such a tension clamp having improved properties in terms of assembly costs.
  • the inventive elastic tension clamp for rail fastening consists of spring steel and comprises a middle loop with two, connected by an arcuate central portion inner legs and loops that connect to the inner leg of the center loop and extend to the free ends of the tension clamp.
  • the loops of the elastic tension clamp are shaped so that they each have a maximum height of at least 20mm and preferably about 24mm above the upper level of the middle loop in the region of the two inner leg in the unloaded state.
  • the upper level of the center loop is defined so that it extends through the upwardly facing surfaces of the inner leg, on which the screw head of a sleeper screw rests. The upper level of the middle loop is thus on the inner legs of the tension clamp as the head of a sleeper screw.
  • the invention is based on the idea to form the two inner limbs of the middle loop subsequent loops of the elastic clamp so that they extend in the unloaded state at least a height H of 20mm above the above-defined upper level of the center loop, which in the preassembled Condition of a height H of about 7 to 8mm more than in the unloaded state corresponds, because in the pre-assembled state, the sleeper screw presses the middle loop by about this amount elastic down.
  • the height of the loops is so far above the support of the screw head of a sleeper screw over the Inner legs, that already in the pre-assembled state, the preassembled head of a sleeper screw is protected, since a possible support of the rail on the preassembled tensioning clamp now no longer takes place in the area of the sleeper screw but in the region of the loops of the tensioning clamp.
  • the outer curvatures of the loops are dimensioned so that they extend slightly beyond the vertical extent of the head of the sleeper screw, bending of the sleeper screw can be avoided.
  • the loops of the tension clamp are designed so that they have no stepped transitions and can serve as a kind of ramp to guide the rail over the ramp in the direction of the rail channel can.
  • the head of a sleeper screw is not exactly defined in terms of its dimensions. In order to ensure functionality during assembly, however, certain minimum dimensions for the head of a sleeper screw must be observed. Thus, it does not make sense to provide the head of the sleeper screw with a height of less than 30mm, followed by the inventive dimensions of the loops follow relative to the inner legs.
  • the maximum height of the loops above the upper level of the center loop in the area of the two inner legs does not exceed about 42 mm. Too large a maximum height would be detrimental because existing rail laying machines which can not sufficiently raise the rail would generally have to slide the rails over the ramps formed by the tension clamps towards the rail channel. Therefore, a maximum height above the upper level of the center loop is advantageous to low the required lifting work while providing the desired protection of a sleeper screw with a commonly used head height of approximately 40mm.
  • the inner legs are substantially parallel to each other. This allows the elastic tensioning clamp to be moved horizontally perpendicular to the rail from its pre-assembly position to the mounting position, as well as to use the tensioning clamp as a replacement for tensioning clamps for final tensioning of the rail in the track from its pre-assembly position to the mounting position by 180 ° must be turned. Finally, the parallel guidance of the inner legs without a constriction of the center loop facilitates automatic pre-assembly.
  • the inner legs on the upper side in the installed position with a flattening in the region of the support of a threshold screw which fixes the tensioning clamp in the installed position.
  • Such flattenings allow the fullest possible contact of the head of a sleeper screw on the inner legs and thereby avoid unwanted deformations of the screw head at positions with too high a local pressure.
  • the tension clamp has a fatigue strength of more than 3 million load changes, preferably more than 5 million load changes, at a tensioning force i. Hold-down force between 10kN and 15kN and preferably around 12.5kN.
  • a tensioning force i. Hold-down force between 10kN and 15kN and preferably around 12.5kN.
  • the high, preferred fatigue strength with normal tensioning of the tension clamp and with an amplitude (vibration amplitude) of at least 2.2kN contribute to the fact that there is in fact an indefinite fatigue strength of the tension clamp as the most stressed component of a rail fastening arrangement.
  • the fatigue strength, i. The vibration amplitude of the tension clamp is at least 2.2mm and thus meets high demands in terms of secure rail fastening.
  • the tensioning clamp is designed such that the rear support arch is designed such that the distance D between the inner leg and the tangential plane running parallel thereto at the loop is D ⁇ 50 mm and preferably D ⁇ 60 mm.
  • the inner legs and the loops in the region of the horizontal extension in the horizontal direction of the inner leg away are not in a horizontal plane. Therefore, the distance between inner leg and the parallel tangent plane extending therefrom is defined because this is the distance relevant to the torsion path.
  • the provision of a high torsional path is advantageous because the torsional path cooperates with the spring stiffness of the material to represent the desired characteristic of the rail fastening.
  • the loops of the tension clamp in plan view describe an arc whose secants S are substantially parallel to the course of the inner leg.
  • the free distance between the arcuate middle part of the middle loop and the free ends of the tensioning clamp is smaller than the diameter of the spring steel in the region of the free ends of the tensioning clamp.
  • the definition of the distance between the free ends and the arcuate middle section of the center loop alone does not preclude the risk of chaining a plurality of tensioning clamps, because snagging of two tensioning clamps can take place at any point since the constriction between the loops and the middle section can also be located at a distance from the free end and also the complex motion sequence must be taken into account when possible hooking of identical clamp.
  • the risk of entanglement is significantly reduced by the above measure. An individual wedging or hooking two clamps is harmless, as long as this does not lead to the formation of long chains that need to be separated from each other with great effort.
  • the rail fastening arrangement according to the invention comprises a tensioning clamp according to the invention and a sleeper screw with a screw head, the like is designed so that it rests on the inner legs of the middle loop. Screw head and clamp are dimensioned so that it does not extend beyond the maximum height of the loops in the preassembled state of the rail mounting with fitting to the inner leg without biasing force screw head. The presence of two loops each side of the center loop thus the head of the sleeper screw is protected in the middle loop and can not be damaged.
  • the tension clamp is supported in the mounting position on the upper side of the rail foot and at the threshold via the angle guide plate lying in a recess in the threshold upper side.
  • This measure serves to be able to initiate transverse forces occurring in the rail area over the largest possible area in the threshold.
  • the sleeper screw is again protected against excessive bending or shearing stresses.
  • tensioning clamp 40 comprises two loops 42 which adjoin a Mitteilteil 44, which is essentially formed of two inner legs 46, which are interconnected via an arcuate central portion 48.
  • the inner legs are, as in particular from Fig. 3 is apparent, substantially parallel to each other.
  • Between the inner legs 46 is located in the pre-assembly as well as in the assembled state in the Fig. 1 to 3 Sleeper screw, not shown, wherein the parallel arrangement of the inner legs 46, a displacement of the tension clamp in the longitudinal direction of Inner leg and can be done relative to the sleeper screw. In this way, the tension clamp can be brought by a sliding movement of a pre-assembly into a mounting position.
  • flattenings 52 can be provided on the inner leg, on which, if appropriate, by means of a washer the head of a sleeper screw (not shown) rests.
  • the sleeper screw is screwed by means of a drive or torque wrench, which engages the head of the sleeper screw in a plastic anchor located in the threshold in a known manner until the desired clamping force is established.
  • the loops 42 close, which in turn consist of a rear support bow 54, outer legs 56 and mutually aligned free ends 50.
  • the outer legs 56 of the loops 42 are curved in both a vertical view as well as a horizontal view, in particular from a comparison of FIGS. 2 and 3 is apparent.
  • Fig. 3 is a top view of the in Fig. 1 shown clamping clamp shown.
  • Out Fig. 1 and 3 It can be seen that the outer leg 56 of the loops 42 is arcuate and shaped so that the loops describe in plan view an arc whose secants are substantially parallel to the course of the inner legs 46.
  • the arcuate course is as uniform as possible in order to transmit the forces and bending moments uniformly to the free ends 50 of the tension clamp.
  • Fig. 2 how out Fig. 2 it can be seen, in the unstressed state of the tension clamp, the maximum height H of the outer leg 56 in comparison to the height of the inner leg by an amount H of 24mm higher.
  • the height difference H moves between 20mm and 30mm and is about 25mm.
  • the height difference is defined so that in the unstressed state of the tension clamp on the symmetrically arranged loops 42 in the region of the highest elevation, a horizontal plane is defined in Fig. 2 is indicated by E 1 .
  • a plane E 2 is defined, which is oriented horizontally in the same way and rests on those positions of the inner legs 46, on which the sleeper screw rests in pre-assembly.
  • the distance between the two planes E 1 and E 2 represents the height difference H, which is at least 20mm.
  • This height difference is chosen so that in the pre-assembly after Fig. 4a greater than the height of the head of a sleeper screw or, when using a washer, the sum of the washer heights and head of a sleeper screw.
  • the height difference ensures that, as based on the Fig. 4b will be explained, the sleeper screw is not damaged when placing the rail during assembly.
  • the inner leg of the tension clamp be stretched down by the sleeper screw and the tension clamp is already deformed elastically.
  • the height H increases by about 8mm.
  • the tension clamp according to the invention is made of spring steel with a substantially circular cross-section.
  • the free ends 50 of the clamp are at a distance from the arcuate central portion 48 of the central portion 44, which is smaller than the diameter of the spring steel, from which the tension clamp is bent in the context of one or more cold forming steps ,
  • This free distance is not apparent from any of the figures shown, since only a view parallel to the planar extension of the free distance between the free ends and the arcuate middle part of the correct size ratios undistorted.
  • This geometry is particularly advantageous when using the tension clamp on problematic sections of road, for example in the region of gradients caused by the slipping of the wheels of rail vehicles high-frequency vibrations that trigger a movement of the rail in the longitudinal direction despite properly fastened tension clamps.
  • the provision of a larger Torsionsabiteses increases the fatigue strength of the rail connection, since not only the torsion of the loop is increased, but also a relative increase in the bending radius in the rail direction.
  • the tension clamp according to the invention has a fatigue strength of more than 3 million load changes, preferably more than 5 million load changes at a clamping force between 10kN and 15kN and preferably at a bracing force of about 12.5kN.
  • a suitable spring steel such as 38 Si 7 as well as by the shape of the clamp the desired high fatigue strength can be ensured at high clamping force.
  • a high fatigue strength in connection with the inventive design of the tension clamp allows a rail fastening assembly with low installation costs.
  • additional installation effort is avoided after pre-assembly, because bending of the sleeper screws is avoided when placing the rail.
  • a reassembly of a rail fastening after reaching its maximum life due to the very high fatigue strength is avoided.
  • the shaping of the tension clamp with a very wide arc D in the horizontal extent avoids unintentional loosening on problematic sections of track, or at least reduces the need for tightening or readjusting the rail fastening arrangement.
  • Fig. 5 illustrates the rigidity of the tension clamp according to the invention on the basis of the force / displacement curve, which was measured at the tenth loading and unloading and thus is no longer influenced by occurring in the first loads with subsidence phenomena. It can be seen that with increasing load, represented by the force applied on the ordinate, just above a load of 13kN, a spring travel increasing proportionally to the load results up to 16.3 mm, as can be seen from the abscissa value associated with an ordinate value of 13kN read. Above this load of about 13kN, the middle loop of the tension clamp comes in contact with the rail foot, which is why the spring travel no longer appreciably increases with further increasing load. Out Fig. 5 It can be seen that the tensioning clamp according to the invention can absorb a very high load of up to 13 kN with a long spring travel.
  • Fig. 4a and 4b show the tension clamp according to the invention as part of a rail fastening. It is Fig. 4b consciously with respect to the shaping of all components to the state of the art Fig. 6 ajar and illustrates the advantage of the tension clamp 40 of the invention. It is shown in Fig. 4a and 4b the section of a threshold 10 with a recess 12, which merges on the one side in the newly executed region of a rail channel 14 and on the opposite side has a contact edge 16. In the recess 12 and in contact with the abutment edge 16, an angled guide plate 18 is used, which is tuned with respect to their shape on the recess 12 and the abutment edge 16 of the threshold 10.
  • the angle guide plate 18 has a groove-shaped recess 20, in which in mounting position the tension clamp 40 with their rear support arches 28 are used.
  • one or more elastic intermediate layers 22 between the angled guide plates of the attachment points can be used as needed.
  • the elastic intermediate layer should act as an insulator on the one hand and on the other hand selectively produce the desired Schienenkopfeinfederung in coordination with the other components.
  • the tension clamp 40 is attached via a sleeper screw 24 to the threshold 10 and braced against it.
  • the sleeper screw has an only indicated shaft, which is provided with an external thread and in an in Fig. 4a and 4b not shown dowels in the threshold 10 is attached.
  • the sleeper screw 24 has a widespread head 26, which is in the in Fig. 4a shown pre-assembly position on the unbiased, ie unloaded elastic tension clamp either rests or is screwed so far into the threshold that it is at least at a small distance to the tension clamp in the unloaded state.
  • the tension clamp 40 As can be seen from the comparison of the height specifications of the tension clamp 40 above the top of the threshold, has in the right in Fig. 4a pre-assembled position, the tension clamp a greater height above the threshold than in the mounting position, the left in Fig. 4a is shown. This is due, on the one hand, to the fact that, in the pre-assembly position, the rear support arches 28 of the tension clamp are not yet received in the channel-shaped depression 20 of the angled guide plate 18 and, secondly, that in the assembly position, the inner legs 46 are pressed elastically downward by the clamping force of the sleeper screw. How out Fig. 4a it can be seen, the head 26 of the sleeper screw is sized or matched to the dimension of the tension clamp that the head 26th does not protrude above the plane defined by the top of the tension clamp.
  • a rail 32 may not be raised sufficiently high above the preassembled rail fastening assembly upon insertion into the rail channel 14, such that the rail will rest on the rail mounting structure.
  • the tension clamp 40 is designed such that the outer limbs 56 of the tension clamp 40 extend so high over the inner legs 46 that the weight of the rail no longer rests on the head 26 of the sleeper screw 24 and therefore the Threshold screw does not bend.
  • the height H is to be provided in such a way that the elastic deformations occurring in the region of the outer leg 46 are also taken into account when the long, heavy rail is placed on top.
  • the outer leg 56 acts due to the arcuate course in the in Fig. 4a and 4b shown vertical sectional view as a ramp that supports the lifting of an overlying rail in the area 60, so that the rail can be introduced into the rail channel 14.
