Definitions

  • the invention relates to a threshold shoe with a bottom and side walls, which are made of an elastic material, wherein on the floor and this superior spring are arranged demente and spaces between the spring elements are formed, and a method for producing this threshold shoe, after an elastic material, a bottom and side walls of the threshold shoe are made by vulcanization in a mold, wherein on the bottom spring elements are arranged such that remain free between these spaces.
  • Elastic sleeper sheathings are often used in the area of solid lanes as elastic decoupling between the track and the ground.
  • the entire threshold that is, for example, a monobloc or biblock threshold, may be provided with an elastic sheathing, e.g. of natural rubber (NR), styrene butadiene rubber (SBR) or vulcanizates of ethylene-propylene-diene monomer (EPDM).
  • NR natural rubber
  • SBR styrene butadiene rubber
  • EPDM vulcanizates of ethylene-propylene-diene monomer
  • PUR polyurethane
  • EPDM mainly cellular material on urethane
  • NR / SBR basis is placed on the bottom of this sheathing in order to be able to set a corresponding vertical elasticity.
  • This cellular material is usually plate-shaped.
  • the threshold shoe is integrally formed and has an integrally formed sealing bead on the upper threshold shoe edge, which has a rail base towards the cranked, anchored in the circumferential groove of the rail base sealing head high extensibility.
  • DE 698 07 31 T2 again proposes a rigid shell for the threshold shoe, so that this retains its tightness under conditions even if a conventional shoe made of elastic material would run the risk of tearing or breaking through.
  • elastic segments are used under pressure and shear elastic preload.
  • the object of the present invention is to maintain the damping characteristic of a sleeper shoe as unchanged as possible even in humid environmental conditions.
  • This object of the invention is achieved by the above-mentioned threshold shoe, in which the interspaces are at least approximately completely filled with a filler made of a second elastic material, the secant rigidity of this second elastic material being maximally so high under quasi-static loading according to DIN 45673, that the deflection characteristic is not or only insignificantly influenced by the spring elements during their loading, as well as by the method according to the invention, according to which a derar tiger filler the spaces is arranged at least approximately completely filling.
  • the water absorption capacity of the threshold shoe is reduced to a minimum in this area - the accumulated water there may be production reasons or by penetrating water from the outside - where due to the elastic materials, in particular the elasticity of the sleeper shoe itself, a squeezing This water can be done during train crossings by the elastic deformability of the threshold shoe during the load. It is not absolutely necessary to provide drainage openings for penetrating water in the sleeper shoe itself, as has also been partly described in the prior art.
  • the low secant rigidity of this second elastic material of the filler ensures that this leads to no or no substantial increase in the overall rigidity Contributes to the system, so the deflection characteristic of the threshold shoe is determined essentially exclusively by the spring elements, and thus the design of this damping system can be performed easily.
  • the elastic deformation of the spring elements by the filler due to its elasticity, not hindered.
  • this filler at least approximately fills the interstices, the residual volume of water in this area is zero or vanishingly small, so that the formation of ice in the winter does not or hardly influences the vibration damping.
  • the filler has a secant rigidity which amounts to a maximum of 10% of the secant rigidity of the spring elements. It is thus realized a sufficiently high distance to the secant rigidity of the spring elements, so that so the function of this filler on the essentials, namely to avoid the accumulation of water in the bottom region of the threshold shoe, can be concentrated.
  • the filler may also have a secant rigidity which is at most 5% of the secant rigidity of the spring elements.
  • a filling height of the filler is greater than a spring element - A -
  • the filler extends substantially to at most the height of the highest spring elements, as this "squeezing" of any existing water from the threshold shoe is facilitated.
  • the filler at least a portion of the spring elements, which are formed with a lower spring element height than the largest spring element height, is arranged overlapping in the horizontal direction, so that therefore at different high spring elements, the threshold itself substantially rests on a flat surface, which is not or hardly by the arranged above it - viewed in the direction of the threshold - filler is influenced by the low secant rigidity of the second elastic material of the filler, the damping behavior of the lower height spring elements.
  • the filler may overhang the spring elements by a value in height selected from a range having a lower limit of 1 mm and an upper limit of 10 mm. Exaggerations of the filler with respect to the spring elements selected from this range have shown in practical experiments a very good ratio between space filling by compression of the filler on the one hand and maintaining the spring characteristic by the spring elements on the other. Below 1 mm, the compression of the filler by the weight of the threshold is so low that, although an improved space filling of the interstices by the compression of the filler is observable, but from this value, a significant improvement of this effect is observable. Excessive increments greater than 10 mm may stiffen the filler, which may also stiffen the entire system of spring elements.
  • the filler extends beyond at least individual spring elements by a region which is selected from a range with a lower limit of 2 mm and an upper limit of 8 mm.
  • At least one surface of the filling material which can be turned over is hydrophobic, on the one hand better avoiding accumulation of water in this area and, on the other hand, better “squeezing" of the water by traveling rail vehicles, especially if foam is used as the filler ,
  • the filler itself already has hydrophobic properties
  • the surface of the filler is rendered hydrophobic, for example.
  • This is sprayed with a silicone oil, wherein preferably the entire surface is hydrophobicized in cellular material.
  • This embodiment of the invention makes it possible, e.g. also to use open-cell material, whereby the range of usable materials for task solving can be broadened.
  • the maximum water absorption capacity of the filler according to ASTM D 1056 can be in particular a maximum of 5% by volume, preferably a maximum of 4% by volume.
  • the second elastic material of the filler used is preferably a material selected from a group comprising HD-PE (High Density Polyethylene), PP (polypropylene), PUR, NR, SBR, EPDM, EPS (expanded polystyrene foam), XPS (extruded polystyrene foam ), EVA (Ethyl Vinyl Acetate), TPE (Thermoplastic Elastomers), such as TPO (thermoplastic olefins), for example EPDM / PP, or TPE-S (polystyrene-poly- diene block copolymers) or TPE-U (thermoplastic polyurethane elastomers).

  • a foam is used as the filler, due to its low intrinsic weight on the one hand and on the other hand the elasticity that can be achieved so that short-term pressurization of the filler does not bring this to a permanent change in shape, but the filler returns to its initial position after pressure relief and thus the space filling capacity is improved.
  • a foam having an average pore size selected from a range having a lower limit of 10 ⁇ m and an upper limit of 3 mm since the elastic behavior of this filler can be made particularly effective, especially if the Surface of the filler is hydrophobic, so that the penetration of water into the pores can be reliably prevented.
