Definitions

  • the invention relates to a frictional-elastic rail fastening for track systems with the features specified in the preamble of the independent claim.
  • a generic rail fastening is from the DE 34 00 110 C2 known.
  • a clamping element is used, which is arranged in the assembled state between a holding plate and a fastening anchor.
  • the clamping element has two legs, which are designed as torsion elements.
  • the Torsionsschenkel have two parallel adjacent spring bar sections, which are integrally connected by a tensioning portion forming and substantially transversely outwardly bent loop. The two spring bar sections of the torsion legs are connected via the connecting crosspiece.
  • the two outer spring bar sections of the torsion leg have at a distance behind the connecting crosspiece in each case a U-shaped turn, which is supported with its free end portion on the connecting crosspiece, while anchoring parts of the rail fastening in the connection to a central web and in each case at a distance above arranged next to the rail run-on slopes for the bracing portions of the clamping element have two projecting to opposite sides supporting flanges for the torsion legs of the clamping element.
  • a rail fastening of the aforementioned type is known in which widen portions of the outer leg of the epsilon-shaped clamping elements enlarging the distance from the inner legs against the rail foot.
  • the mutually facing free ends of the clamping element terminate outside the inner leg.
  • the tensioning element is further designed so that a central web comes to lie in the mounting position at a small distance above the rail and rests in the pre-assembly with its inside on the shaft of the sleeper screw.
  • the clamping element fulfills its task, namely to ensure a good grip of the rail at the threshold.
  • the clamping element is relatively large and complicated. This is accompanied by a correspondingly high production costs, which increases the manufacturing costs of the clamping elements.
  • the previously known clamping elements do not provide a sufficient solution to the following problem: With unusually high loading of the rail with forces tilting of the rail is possible.
  • the Torsionsschenkel of the clamping element and the threshold fitting can be highly stressed in the occurrence of tilting of the rail, namely over-stressed or overloaded. It is therefore desirable to design the rail fastening in such a way that provision is made for this, and even when tilted, it is precluded that the torsion legs of the tensioning element and also the threshold screw connection are overloaded.
  • the tension torque can be generated indirectly only by tightening the threshold or hook screw.
  • the tensioning force of the clamping element acts in addition to the biasing force of the sleeper screw, whereby the screw is additionally loaded.
  • the assembly of the clamping element can be realized only by means of a threshold or hook screw. It is desirable to realize a universal mounting of the clamping element, ie without or with screw, and if necessary without affecting the fferenvorspannkraft.
  • the invention is therefore the object of a rail fastening of the generic type so educate that can be achieved easier assembly.
  • the second plane preferably agrees largely with the first plane.
  • the loop-shaped clamping portions may preferably at least partially have an S-shaped course. With this configuration, a more compact construction of the fastening system can be achieved, as will be seen.
  • the loop-shaped clamping portions are preferably formed in the plan view in their rail-facing part substantially circular or oval. Connection transitions between the individual functional zones are equipped with large radii or radius transitions in order to ensure optimum voltage profiles in the material of the clamping element.
  • the individual radii or radii transitions along the course of the clamping element can be of different sizes.
  • the angle between the above-mentioned planes, ie between the first plane and the second plane, preferably lies between 5 ° and 30 ° in the non-tensioned state of the clamping element.
  • the ends of the loop-shaped clamping portions may be formed as straight sections. These straight line sections preferably run parallel to one another.
  • the ends of the loop-shaped clamping sections may have a groove-shaped recess which is formed as a bearing surface on the fillet radius of the rail foot. This makes a defined and safe installation on the rail foot possible.
  • each loop-shaped clamping portion may have a first contact surface in the side region of the clamping portion to rest on the rail foot, which also contacts the rail when a tilting of the rail in case of high horizontal forces on the rail head (first overload case), but with a greatly reduced lever arm. Furthermore, each loop-shaped clamping portion may have a second contact surface for engagement with the fastening anchor, which contacts the fastening anchor in the event of a second, stronger overload case of the forces acting on the rail beyond the first overload case.
  • the retaining plate can be integrated in a rail underlay plate.
  • the retaining plate and the fastening anchor may be formed in two parts.
  • the retaining plate and the fastening anchor can be connected by means of a hook screw or held together.
  • the fastening anchor may be plate-shaped and fixed by a screw.
  • the retaining plate and the fastening anchor are integrally formed.
  • the fastening anchor may have contact surfaces for the loop-shaped clamping sections on its underside in its rail-facing, lateral end regions. Furthermore, the fastening anchor may have on its underside in its side facing away from the rail, lateral end portions each have a first groove-shaped detent recess for engaging the clamping element in a pre-assembly. In addition, it can be provided that the fastening anchor has on its underside in its side facing away from the rail, lateral end portions each have a second groove-shaped locking recess for engaging the clamping element in a neutralization position. Finally, the fastening anchor may have on its underside two groove-shaped contact surfaces for the system of the torsion leg of the clamping element in the final assembled state.
  • the fastening anchor is formed by the sleeper screw or a washer connected thereto.

It can have two contact surfaces for the installation of the clamping element in its mounted state. Furthermore, the holding plate on its underside extending in the direction of the longitudinal axis of the rail projection to engage in a corresponding recess in the threshold.

  • the arcuate or trough-shaped recesses are helpful when the clamping element 1 is inserted from the rear by means of a mounting tool, ie it is no loosening of the mounting anchor 4 is required.
  • the depressions serve to push through the clamping element without much effort from the rear. Without the recesses, the clamping element would have to be completely compressed when pushed through to its final tension state.
