  • the rails fastened by means of the components and fastening points which are improved by the invention usually have a rail foot, a rail web standing on the rail foot and a rail head carried by the rail web.
  • the known rail fastening systems (see, for example, WO 2006/005543 A1 and the other patent publications cited below) and rail fastening points produced therefrom accordingly respectively typically comprise' as components from which they are assembled, a guide plate (see, for example, WO 2010/091725 A1), which is provided for laterally guiding the rail, a W-shaped tension clamp provided for placement on the guide plate (see, for example, WO 2012/059374 A1) and a tension element (see, for example, WO 2014/029705 A1), which is provided for clamping the tension clamp against the ground surface (see for example WO 2006/005543 A1).
  • supplementary elements may also be respectively used, such as optional shims (see, for example, WO 2011/110456 A1), which are used to adjust the height of the rail above the ground or to distribute the loads occurring when passing over the rail by a rail vehicle, elastic intermediate layers (see WO 2005/010277 A1, for example), which are likewise laid under the rail or the other plate-shaped components of the system in order to ensure a certain flexibility in the direction of gravity for the rail in the fastening point formed respectively from the system, and insulator elements (see, for example, WO 2015/051 841 A1), which are typically located between the suspension element and the foot of the rail to be fastened to ensure optimised electrical insulation against the ground surface.

  • insulator elements see, for example, WO 2015/051 841 A1
  • the W- or ⁇ -shaped tension clamps are usually one-piece and bent in one go from a spring steel wire.
  • they have a usually V- or U-shaped middle section which has two legs aligned parallel to each other. These legs define between them a free space through which the respective tension means, typically a sleeper screw or a bolt, is guided into the ground surface by means of its shaft.
  • the legs are usually connected to each other via a base section which faces the rail associated with the front side of the tension clamp.
  • a torsion section is typically respectively formed, which emanates from the respectively associated leg of the middle section, directed laterally outward.
  • the torsion sections are bent in the direction of the underside of the tension clamp so that the suspension element can be supported during use on a support surface in the region of the torsion sections in a support zone formed on the respective torsion section, which is designed on the upper side of the component carrying the suspension element, for example a guide plate.
  • the torsion sections usually merge respectively into a supporting arm, which, when seen in a lateral view, is typically curved in an arc-like manner in the direction of the upper side of the tension clamp and, when seen in plan view, is aligned in the direction of the front side of the rail to be fastened.
  • the free end sections of the supporting arms typically point in the direction of the middle section. With these end sections, the tension clamp is supported during use on the foot of the rail to be fastened.
  • the support zones of the supporting arms and the torsion sections are located regularly on a straight line which is aligned substantially parallel to the axis of symmetry of the tension clamp.
  • the elastic flexibility and thereby the hold-down force exerted on the rail via the supporting arm can be adapted to the requirements and stresses that result in practical use, via the shape of the supporting arm as well as the form and alignment of its end sections.
  • the spring behaviour of the tension clamp can be influenced by the shaping of the torsion sections and of the middle section as well as the transition sections which may be present between the middle section and the torsion sections as well as between the torsion sections and the supporting arms.
  • the guide plates usually have on their upper side form elements on which the suspension element to be arranged on the respective guide plate is guided in such a way that, during use, it retains its position even under the loads occurring in practice.
  • the suspension element to be arranged on the respective guide plate is guided in such a way that, during use, it retains its position even under the loads occurring in practice.
  • fillet-like depressions, in which the torsion sections of the suspension element are seated during use, or a central web can be formed on the upper side of the guide plate, on which the middle loop is guided and supported.
  • the tension clamps are excited to vibrate when a train passes over the rail held down by the tension clamps.
  • Periodically recurring faults on the rail or on the wheels of rail vehicles can lead to resonance peaks. If these are close to one of the natural frequencies of the tension clamp, there is a dramatic increase in the vibration amplitude, in particular in the region of the supporting arms of the tension clamp. The result is a premature, sudden failure of the tension clamp due to breakage, which typically occurs in the region of its torsion sections or in the transition region of the supporting arms to the torsion sections.
  • the first of the proposed measures comprises the arrangement of vibration-damping additional elements on the tension clamp. These, for example, disc or tube-like additional elements are to be arranged in particular in the region of the supporting arms.
  • vibration absorbers while highly effective, are also destructive, so that the article comes to the conclusion that the practical usability of such absorbers is questionable.
  • the article has proposed an enlargement of the support surface provided for the tension clamp on the respective guide plate.
  • increased resonances can increase the natural frequencies of the tension clamps to such an extent that they are outside the range in which they are typically excited in practice.
  • the relative movements, which are performed by the tension clamp and the guide plate when passing over the rail laterally guided by the guide plate and held down by the tension clamp, as a result of inevitable horizontal and vertical movements of the rail proved to be problematic.
  • the object has arisen to identify practical measures for the design of one or a plurality of interacting components for a rail fastening point with the aim of maximising the life of the system formed from the components or of its individual components.
  • the invention proposes the particular designs of a tension clamp or guide plate which are generally disclosed in Claims 1 and 7 , wherein each of these design measures alone, i.e. isolated from the other measures, provides a solution to the above object and thus leads to an improvement in the vibration behaviour of the overall system and in particular the tension clamp installed in this system. It goes without saying that the measures proposed here by the invention can be combined in any way with each other in order to develop an optimised effect.
  • a fastening point according to the invention is accordingly characterised in that a tension clamp designed according to the invention or a guide plate designed according to the invention are installed therein.
  • the tension clamp according to the invention and the guide plate according to the invention respectively individually lead to a significant improvement in the vibration behaviour, so can be used as alternatives to each other, but produce an optimal result when combined together.
  • a measure for improving the vibration behaviour of the tension clamp itself is thus, in each of the supporting arms of the tension clamp, to shift the zone with which the respective arm is supported on the rail foot during use, such that the natural frequency is moved to a region in which it no longer causes vibrational excitation in practical use.
  • the invention proposes a tension clamp for elastically holding down a rail for rail vehicles, which comprises a foot, a web standing on the foot and a rail head carried by the web, which in a conventional manner comprises
  • the support sections of the supporting arms point respectively laterally outward with respect to the middle section of the tension clamp, such that when viewed in plan view from above with respect to the tension clamp, the straight lines, which respectively connect the centre of the support zones of the supporting arms with the centre of the support zone of the torsion section associated with the respective supporting arm, intersect in a region located on the rear side of the tension clamp.
  • the natural frequencies of the tension clamp can be effectively increased so far that they lie outside of the excitation frequencies that occur during practical use, in that the support zones of the support sections of the supporting arms and the torsion sections, to which the respective supporting arm is connected, are no longer located on a line parallel to the axis of symmetry of the tension clamp, but on a straight line, which encloses an acute angle running in the direction of the rear side of the tension clamp. Due to said invention, the durability of the tension clamp is significantly improved, without this leading to a significant change in the resilience behaviour. The invention thus eliminates the problems encountered in the existing practice, without a fundamental redesign of the components of a rail fastening system being required.
  • the invention does not exclude that the measures proposed in the prior art with regard to optimised dynamic behaviour of the tension clamp (see, for example, the above-mentioned article by Maximilian Steiger) are also implemented in a tension clamp according to the invention, based on the design according to the invention to achieve a further optimised vibration behaviour.
  • optimised dynamic behaviour of the tension clamp see, for example, the above-mentioned article by Maximilian Steiger
  • these include, in particular, the reduction in the amount of bending of the supporting arms over the support surface on which the tension clamp is mounted, and the increase in the support zones, with which the support sections of the supporting arms are seated on the rail foot during use.
  • the straight lines running through the centres of the support zones of the respectively associated support sections and torsion sections preferably enclose an angle of at least 60°, in particular more than 60°, or at least 90°, in particular more than 90°, in order to establish the greatest possible distance between the natural frequencies of the tension clamp and a possible excitation frequency.
  • the angle between the straight lines, seen in plan view with respect to the tension clamp is a maximum of 120°, in particular less than 120°.
  • an additional optional design element may be used, in that the supporting arms, seen in plan view with respect to the tension clamp, extend respectively outwardly away from the middle section, starting from their associated torsion section.
  • the following feature may further contribute to the durability and optimal resilience behaviour of a tension clamp according to the invention, if, also optionally, when viewed in plan view with respect to the tension clamp, the support zones of the supporting arms project in the direction of the front side of the tension clamp, with respect to the free end face of the base section of the middle section.
  • a vibration behaviour of the tension clamps formed according to the invention may occur if the following applies for the distance AS, measured parallel to the axis of symmetry of the tension clamp, between the centre of the support zones of the supporting arms and the intersection of the straight lines, which respectively connect the centre of the support zones of the supporting arms with the centre of the support zone of the torsion section associated with the respective supporting arm, and for the distance AG, likewise measured parallel to the axis of symmetry, between the support zones of the supporting arms and the centre of the support zones of the torsion sections:
  • a guide plate according to the invention is provided with form elements, i.e. structural design features, which protect the supporting arms of the tension clamp arranged on the guide plate against excessive vibration amplitudes during use, which occur in the case of a vibration excitation in the range of one of the natural frequencies of the tension clamp.
  • a support surface is provided on the free upper side for a tension clamp to be positioned on the guide plate, said tension clamp serving to provide elastic holddown in the fastening point, wherein this clamp applies the elastic hold-down force via two supporting arms, which are supported during use with their free end sections on the foot of the rail fastened in the fastening point.
  • at least two stops are provided on the support surface, which limit at least the movements of the supporting arms of the tension clamp perpendicular to the contact surface, when the tension clamp is positioned on the guide plate.
  • the stops can be designed in the manner of supports which carry on their respective free end face a fillet-like seat for the associated supporting arm of the tension clamp.
  • the stops In order to dampen the shocks associated with the striking of the supporting arms on the stops, the stops have an elastic material on their free end face associated with the respective supporting arm of the tension clamp, said material serving to dampen a contact with the associated supporting arm.
  • a tension clamp mounted on the guide plate according to the invention it may be beneficial to form depressions on the support surface in a guide plate according to the invention, the tension clamp being supported in these depressions during use by means of a respective section, and to cover these depressions with a damping or elastic material in the region of their contact surfaces which come into contact with the tension clamp.
  • This material may be formed as a separately manufactured insert or as a layer formed integrally bonded onto the material of the guide plate.
  • the depressions may be expedient to adapt the depressions to the shape of their respectively associated sections of the tension clamp, in such a way that during use the section of the tension clamp seated in the respective depression tightly engages positively on the contact surface of the depression, at least over part of its length, so the contact length between guide plate and tension clamp is increased.
  • An optimised effect of this measure is obtained when the sections of the tension clamp assigned to the depressions are torsion sections, which are bent in a continuous curve towards the underside of the tension clamp, and the depressions are formed in an arc-like manner, corresponding to the curve of the torsion sections, so that in a tension clamp positioned on the guide plate the torsion sections are seated in the associated depressions engaging tightly and positively over a partial length of their curve path.
  • the guide plate is, as usual in the prior art, preferably made in one piece out of a plastic, in particular a fibre-reinforced plastic.
  • a fastening point according to the invention in which a rail for a rail vehicle comprises a foot, a web standing on the foot, and a rail head carried by the web, said rail being fastened to a ground surface, has a guide plate acting against the lateral edge of the foot of the rail for laterally guiding the rail and a tension clamp positioned on the guide plate, which is supported with the free end sections of its supporting arms on the foot of the rail, in order to exert an elastic hold-down force on the rail.
  • the tension clamp or the guide plate are formed in accordance with the invention, wherein in this case it is also self evident that is possible for either only the tension clamp or only the guide plate to be formed in accordance with the invention, but when both the guide plate and the tension clamp correspond to the provisos according to the invention optimal results are achieved.
  • a fastening point can comprise a tension element in a conventional manner, such as a sleeper screw or a sleeper bolt, by means of which the tension clamp is braced against the ground surface.
  • the tension element in question is typically guided through the space delimited between the legs of the middle section of the tension clamp, and through an underlying opening of the guide plate down to the ground surface, where it is anchored.
  • the anchoring can be effected in a likewise conventional manner by means of a dowel recessed into the ground surface or another suitable fastening.
  • an insulating element may be arranged between the end sections of the supporting arms of the tension clamp and the rail foot, which electrically insulates the tension clamp against the rail and comprises dampening or elastically yielding material at least in sections.
  • the insulator may be formed, for example, as a sandwich element, in which electrically insulating layers are combined with damping or elastic layers, in order to achieve on one hand the required electrical insulation and on the other hand a vibrational separation of the rail from the tension clamp, with sufficient resistance against the hold-down forces applied by the tension clamp.
  • the measures referred to here relating to the insulating elements already contribute in their own right, i.e. independently of the above-described inventive design features, to improving the durability of the tension clamp used in a rail fastening point according to the invention, but of course are particularly advantageous in a design according to the invention of a fastening point.
  • Another component that is used regularly in fastening points of the type in question here is an elastic intermediate layer which is usually arranged between the rail foot and the ground surface to give the support of the rail a certain flexibility in the direction of gravity.
