Sleeper shoes of the type defined above.

[0003] Elastic sleeper sheaths are often employed in the field of ballast.less tracks to elastically decouple the track and. the sabs träte. in this manner, the entire sleeper, r. o. , for example, a meneblock or twin-block sleeper, can he provided with an clastic sheath, for example formed from, natural rubber (NR), styrene-butadiene rubber (SEP 1 or vulcanisâtes formed from ethylene--propylene-diene monomers (EPDb) . Currently, for the most, part, cellular material based on polyurethane (FOR), EPDM or HR/oBR is placed on the floor of this sheath in order to be able to provide it with appropriate vertical elasticity.

This cellular material is normally in the shape of a plate. In addition, it is possible to produce the vertical elasticity by means of individual spring elements. The elastic behaviour is imparted in this case by the deformabiiity of these spring elements, made possible by the spaces between the spring elements. However, on open stretches, u problem arises, since water can col lent: between the spring: elements. When tempers meres are low, ice is formed from this, on ; oh reduces the elastic behaviour of the s p r i n g e i erne n t s,

i 0004 I In order to overcome 'this problem,, in Do 92 02 013 01, proposes a roil sleeper lor anchoring railway tracks in a be.; i act loss superstructure installed in appropriate recesses of the superstructure with its lower region in a sleeper shoe consisting of a floor plate and j acoral wails forrnod from aa elastic material, wherein In the region of the upper edge of the lateral wai is, an a ; ;.··· round sealing conhoction is provided against the lateral surfaces of the rail sleeperV

[00Ö5] A similar solution is provided in DE 29? 19 400 111, wherein the rail sleeper is provided with an ail -round groove, the sleeper shoe is formed as one piece and has a moulded-on sealing bead formed at the upper edge of the si neper shoe which has a sealing head with a high ductility which is cranked inwardly of the rail sleeper and which can be anchored In the ail-round groove of the rail sleeper, 100061 In order to increase the seal, DE 698 0? 31 T2 again proposes,, liner alia, a stiff shell for the sleeper shoe, so that it retains its: seal even under conditions when a con a e nr. ion a I. shoe formed from elastic material would run the risk of being ripped apart or being burst. In this case, elastic segments are installed under compressive and shear ela s t i c ore-s t re ss > [0007] In principle, it is also known to provide extensive mass-spring systems which are used to dampen vibrations in. the track construction provided with a plurality of elastic support portions disposed in a spaced apart manner on a support layer, wherein, a non-load-bearing filler layer which partially fills the space between the support portions and which prevents the ingress of water into this space is provided, as described, for example, in CD 513 302 A., Ido damping element described1 therein additionally comprises a watertight skin which envelopes the filler and the support portions, The difference between this unci sleeper shoes is that here; the sleeper dees net rest on the spring elements themselves, but a support plane is necessarily provided in order to allow the weight to be distributed ever the individual. spring elements. This support plate also functions as a barrier against the ingress of water into the spaces formed between: the spring elements and the filler on the lower side of this damping element - [00081 Ihn aim of the present invention In to maintain toe damping: characteristics of a sleeper shoe as constant as possible, even under wot eavirohmeatai. conditions, [0009] This nib. of the invention is accomplished by means of the sleeper shoe defined in claim i and in the inventive method by means of which the gaps are at least approximately completely filled by a filler of this type. Because the gaps are at least approximately completely filled, the water absorption capacity Of the sleeper shoe in this region is reduced to a minimum the wafer which collects here may be that .necessarily formed during msouf3.chure, or from the ingress of water from outside - wherein because oi the elastic materials, in particular the elasticity of the sleeper shoe itself, the water can. be squeezed out when a train runs over it by means of the elastic derornate. ;rt y of the sleeper shoe during ioadrng. This means that it is not entirely necessary to provide drainage openings for incoming water in the sleeper shoe itself, as has occasionally been described in the prior art. Because of the relative secant stiffness with respect bo the secant stiffness of the spring element itself, it is possible on the one hand to use spring elements with very different spring feeds, and on the other hand, because of the low secant stiffness of this second elastic material of the filler, it does not increase or does not contribute significantly to ah increase in the overall stiffness of the system, x . o. the deflection characteristics óf the sleeper shoe are essentially exclusively determined by the spring: elements, and thus designing this damping system is easier. Thus, the elastic deformation Of the spring element i.s not inhibited by the filler because of the elasticity thereof. Because this filler at least approx ire se! y completely fills the gaps, the volume which is left for eater in this region is aero or cb sapooarieqiy small, so that even when ice forms in the winter., the vibrational damping is not or only barely affected, [0010] in order to improve this effect, in accordance with en embodiment of the invention, the filler has a secant stiffness which constitutes a maximum of 10¾ or the secant stiffness of the spring element. This separates its secant stiffness sufficiently from the secant stiffness of the spring element so that in this manner, the function of this filler tan be concentra red on the essential function, namely preventing water from, collecting in the floor region of the sleeper shoe.

[0011] In particular, the filler may also have a secant stiffness which :·; a max.·.;·.un of ;5% of the secant stiffness of the spring element, [0012] It is also possible for a fill height of the filler to be larger than a height of the spring elements or of the shortest spring element· in this directron. In this manner, this filler., after insertion of this sleeper, is compressed so that the gaps can be filled to a greater proportion with this filler. In the case in which the spring elements have a different height - the scope of the invention includes the possibility of using spring elements with different secant stiffnesses or spring elements with different dimensions, so that the spring characteristics of the system can be adapted appropriately, for example in order to accommodate curves - then preferably, the filler essentially extends to a maximum of the height of the highest spring: element, so than in this· manner, any water present in the sleeper shoe nan be "squirted out" more easily.

[0013] In accordasse with a vur isti or: ,· it is also possible in this regard for the filler to noser horizontally at least a portion of the spring elements which are configured with a smaller spring element height than the largest spring element height, an that with spring elements with different heights, the sleeper itself essentially lies on a flat surface, whereby, because of the low secant stiffness of the second elastic material of the filler, the damping behaviour:, even of the spring: el.eo.enls which are shorter, is not or is hardly affected by the filler which is disposed over them in the direction of the sieepet, [0014] The filier pay overtop the spring elements by a value selected from, a range with a rower limit of 1 mm and an upper limit of 10 mm, lut excess height of the filler with respect to the spring element which is within this range has proved in practical tests to have a very good relationship between space filling by compression of the filler on the one hand and retention of the spring characteristics by the spring on the other hand:. Below X mm, the compressioh of the filler by the tare weight of the sleeper is so low that/ although improved space filling of the gaps can be observed by compression of the filler, a substantial, improvement in this effect can be observed above this value, excess heights of mere than 10 mm stiffen the filler in some circumstances, such that the system of spring elements as a whole could be c orne s t i. f f en ed.

[SOI5] Preferably, the filler protrudes beyond at least some spring elements by an amount which is selected to be in the range with a lower limit of 2 mm and an upper limit of 8 mm.

[DDlfj It is also possible for at least one of the surfaces of the filler which can be made to face the sleeper to be hydrophobic ärmere upon on the one hand, the collection of water In this region can be better prevented, and on the other hand, the water can be "squirted out" better by railway vehicles passing ever it, in. particular when foam is used as the filler, [0017] In this manner, on the one hand it is possible for the filler itself to already have hydrophobic properties:, and on the other hand it is possible to make the surface of the. filler hydrophobia., for example to spray it with a silicone oil, wherern with cellular materials, the whole surface is preferably rendered hydrophobic. By means cf this exdsodimeht of the invention, it is: even possible, for eraiaple, to use open·" cel led material, whereupon the spectrum: of substances which can be used to accomplish this aim can be broadened, [QG18] fro tersely, fillers are used which have a water absorption capacity in accordance with ΆΟΤΒ D 105 6 (or DIM ISO 289¾} which is a maximum of T% by volume, ín order to further improve the basic effect of the invention, [DOIS] In this respect the maximum water absorption capacity of the filler in accordance with ASTM D 1056 for Did ISO 2896} may in particular be a .maximum: of S% by volume, preferably a maximum of 4% by volume. f0Q20] In accordance with the invention, a substance may be used as the second elastic material which is selected from a group comprising HD·····PS (High Density Polyethylene} ,-BP (Polypropylene}, PUR, NR, SBR, EPDM, EPS (Expanded Polystyrene Foam ; , XPS (Extruded Polystyrene Foam} , FRA (Ethyl Vinyl. Acetate), TPE {Thermoplastic Elastomer} such as, for exemple, TPO (Thermoplastic Olefin}, for example EPDbl/Pi?, or TPE-S fPolystyrene-PoXydrsne Block copolymer) or TPE-U (Thermoplastic Polyurethane Elastomer} . In particular, very good results were obtained with these substances as regards accomplishing live object or the present invention·.

[00/ i ] Preferably/ a foam is used. as the filler which has a low tare weight on rho one hand and on the other hand/ an elasticity that can be obtained such that short-term compression of the filler does not cause it to change its shape permanently, hut that after compression/ the filler can return, to its initial position:/ thereby improving the gävp-f i 11 ino capabi 1 i ties < [0012]; Particularly preferably/ a foam is used which has a mean pore sire which is selected from a range with a lower limit of 10 pm and an upper limit of 3 mm, since In this mannet/ the elastic behaviour of this filier can he established in a particularly effective manner, in particular when the surface of the filler is rendered hydrophobic/ so that ingress of wafer into the pores oan be prevented in a more reliable marner·:'.

[0023] Preferably/ a foam is used which has a mean pore site which is selected from a range with a lower limit of 0,2 mm and an upper limit of / mm/ in particular selected from a range with a lower limit of 0.3 mm and an upper limit of 1 mm, [00241 In particular/ however/ in accordance with the invention, a ciosed-ce). 1 elastic foam is used because of the low water absorption capacity of foams of this type.

[0025] A further improvement can be obtained in this manner by adhesively bonding the tiller with the spring elements so that it is fired in position in the sleeper shoe and thus can foe prevented from sliding out, with a simultaneous opening up of spaces. In this regard/ either a suitable adhesive, .e. à glue, may be useo, or on the other hand it is possible to produce the filler by directly fD.am.lng. betűsen the spring elements, thereby bringing about an adhesive ponti to the spring elements:.

[0026] In order to prevent aging due to microbial degradation of the elastic elements of the sleeper shoe in wet surroundings, in accordance with an embodiment; the fid. 1er is provided with a bactericidal or In rom. oldal substance. In this manner, the spring characteristics of the sleeper shoe can be maintained for a longer period when small quantities of water gain ingress info the sleeper shoe. In this regard, silver (silver ions) may, for example, be used as the bactericidal or fungicidal suibstahces, It is also possible to modify the surface of the filler by catalytic grafting using groups or molecules or molecules having sue appropriate action:, (0027] In order to fix the spring elements better an position, they may be vulcanised to the floor of the sleeper shoe, whereupon in addition, gaping of the spaces between the soring elements and filler when railway vehicles pass over them is prevented to a greeter extent. (00281 In embodiments of the method, the filler is mnufactured as: an elastic plate which has depressions formed into it the geometry of which at least approximately corresponds to the spring elements, and this plate is placed on the floor of the sleeper shoe following vulcanisation, or a foamafole raw material is used as the filler, which is initially arranged in the gaps prior to insertion of a sleeper, and then foamed after inserting the sleeper, or the sleeper shoe is manufactured using a 2---component method, wherein a foamatols raw material for the filler is introduced into the mould into the gaps between the spring elements and. teamed during vulcanisât ion. In particular, toy means of the two variations involving direct foaming: of the filler in the sleeper shoe,· the gaps are completely filled; using the 2~ component method, it: is possible to produce the elastic coating of the sleeper in a single operational step, lx both foaming variations are not possible, then the plate embodiment provides for a great deal of variability as regards the very different geometries: of spring eï estes v s ; if necessary, they could also be adjusted directly in situ, a.e, at the construction site, [0029] The invention, will be better understood with tbs aid of the discussion below, made with reference· to tire accompanying drawings, Γ00.3Dt] in the drawings, which are all highly simplified and diagrammatic;

In addition, figures 1 he 3 respectively show sections of a track construction 3 for what is known as a cal last less track, This track construction 3 consists of the sleeper 2, which in this embed imént is known as a short sleeper, the sleeper shoe 1 which goes round the lower region of the sleeper 2 so that most of toe volume of this sleeper 2 is accommodated in the sleeper shoe, a mounting plate 4 via which a rail 5 is fastened no the sleeper ?, wherein In order to fasten the raid 5 to this mounting plate 4, oonventional mounting means which are known; in the prior art can be used, for example in the term of an X- or h-fixing or hock thread fastenings. A first damping element 6 is disposed between the mounting plate 4 and the sleeper 2; a. second damping clement 8 in the form of a rail pad is disposed between a foot 7 of the rail, and the mounting plate 4, [003-¾ 1 Th® sleeper 2 may be connected to a farther sleeper 2 via a cross'-'brace to a oross-sleoper -not shoe®} , Furtnermore; the sleeper 2 i.s normally accommodated In a recess in a base plate/ in particular formed from concrete, ;00 21 ; This principal cox^siruction is already known in the art; in part from DE 92 02 613 Ül mexlf ioned above, [0036] Howevorf the invention is not limited to short s : eepers; the sleeper shoe I may also be used for What is known as long sleepers, Furthermore, it is possible to produce the sleeper 2 as a monoblock or twin-block sleeper, for example an h-sieeper. still further,· the anvention is not limited to concrete support plates for accommodating the sleepers; ballast substrates etc, may also be employed, [0037] As can be seen better in Figure 3, the sleeper shoe 1 corner ; so« a f loor 3 as well as lateral walls 10, 'Bib-like webs 12 are provided at the :,oner surfa.ee 11 of the lateral wails if, which contribute to the damping characteristics of the sleeper shoe 1. These webs 12 are construe r.od so as to increase in height in the direction from, the floor 3 to the raid, 5., so that with respect to the floor 9 the lateral walls 10 - seen in cross-section - are tapered in configuration. In particular; these webs 12 are disposed all around, the entire periphery of the lateral -walls Tfh Thus, there are no free spaces between indiyidual. segments as described; for example, in DE 633 Q? 031 T2 mentioned above for dewatering. Thus, although these free spaces are not. entirely necessary for the purposes of the invention, they may clearly be provided. Furthermore,- the described tapered configuration of the lateral walls 10 is not entirely neuessaty, [00331 In this embodiment of the sleeper shoe 1, spring elements 13: formed ftem a first elastic material of the sleeper shoe: ate formed ön the floor 9 of the sleeper shoe. i - s, produced in one piece with the floor 9 , These spring oie-non no 13 are thus formed so so to const vie to studs, with an at least approximately square cross-scot .-.on (seen In top view; . with the aid of these spring elements 1 3, the deflection characteristics and thus the damping behaviour of the syeicon i.e. the sleeper shoe 1 - in addition to the damping feature of the damping elements. 6., 8 - are determined, [003 3] it should be uaderstood here that the invention concerns the construction of the sleeper shoe 1 itself, and SO having regard to the farther damping elements 0, 8, it should be noted that, for example, that the dumping element 6 does not necessarily have to he present. In addition, having regard to the damping characteristics of these damping elements 6, 8, for example by different combinations of hard and soft segments for these damping elements 8, 8, reference should bo miade to the appropriate prior art, [0040] Furthermore, it is not absolutely neoessory for the sprang element 13 to be prepared from, the material of the floor 9 of the sleeper shoe, in. particular to be formed as one piece therewith. Thus, in the context of the invention, it fs entirely possible for those spring elements 13 to be subsequently placed on the floor 9 of the sleeper shoe 1, for example in the form of a rubber mat. curthermore, it is not entirely necessary for these damping elements 13 to have an at least approximately sgnare cross-section; as an example, other cross-sect uns, for example round, rectangular, or polygonal cross-seem ions, also fall within the context of the invention; these different cross-sectional forms - ever; mixed shapes are possible within a single sleeper shoe 1 - can be used to adapt the spring characteristics of the sleeper shoe 1, i,e> of the t rack construction 3 as a whole, to the respective requirements which, for example, may be completely different over carved stretches than over straight stretches.

[0041 j The scops of the invention also encompasses using spring elements 13 will· different diameters - seen in top view --ο and also to adapt the deflection characteristics to the respective cl. roues Lateen and requirements. Thus, for example, combina r. :i on a with thin and thick: spring elements 13 are possible in order, for example, to acoomnodms curves, [00421 The spring elements 1.3 also do not need to be formed as studs, even 1 nough this is the preferred embodiment, but spring siements 13 in the form of strips which at least approximately extend over the entire width of the floor 9 may- he used, [0Ö431 Gaps 14 are formed between the Individual spring: elements 13 in which, in accordance with the invention, a filler 15 is hi sensed. This filler 15 at least approximately completely, and preferably completely fills these gaps 14, [0044] In particular, a closed cell foam is used as the filler 15, preferably selected from a group comprising Hunt, Γ?, PUP, PR, SBR, :dl)h, ERS, XT A, EVA and TP®. In principle, however, open-eelled: foams may also be used, in particular when, as already discussed above, they have been at least super!iciaily rendered hydrophobic or consist of a hydrophobic material. The pore site of the foam may in this regard be selected within a range with a lower limit of 10 pm and ah upper limit of 3 am:. Preferably, all of the gaps 14 between the spring elements 13 in the floor 9 are filled with the filler 15. however, it is also possible, if this should be necessary, to provide the groove™i1 kr depressions between the Webs 12 in trie lateral walls Id with this filler. (0045] la a first embodiment, a fill no.rent 16 of the filler IS in the gaps 14 is dote mined in a manner such that these gaps 14 are at least approximately completely filled, i , e . essentially correspond to the height of a spring element 17. Futthermere, it a second srhodiment, this fill height 16 can oe determined such that the fillet 15 projects beyond the spring elements 13 in the vertical direction, i>e. the fill height 16 is higher than the filler element height 17. This means that this filler 15 is compressed when the sleeper 1 is introduced into the sleeper shoe 1, and thus the gaps id are more securely filled, [0046] In accordance with the invention, the filler 16 has a secant stiff near the maximum of which - as a function of Che first elastic material used for the spring elements 13 and possibly the .floor 9 as well as the lateral, walls 10 - is such that the deflection characteristics via the spring elements 13 when loaded by a railway vehicle passing over it are not or are only affected to an insignia! canr extent, i.e, the overall '"sleeper shoe 1." system is not stiffened.

[:0047] The term "'affected to an insignificant extent:' as used in the context of the invention means that the deflection characteristics of the spring elements 13 are deteriorated by the filler 15 by a maximum of 101 under quasi-static loading (DIM 45673;, [004 5] In particular, the filler 15 has a secant stiffness which is a maximum of 16 to 10% of the secant Stiffness of the spring element 13, [0049] In general, it should fee noted here that the secant stiffness of the spring element 13 under quasi-static loading may be selected from a range with a lower limit of 5 bh/mm and an upper limit of 300 kN/mm in accordance with DIN 45673, [0050] Figure 4 shows a sectional: view of a further embodiment' of the sleeper Shoe 1 in cross-sect inn;. Here, the spring elements 13 are of different heights, in this manner, thé deflection, i<e< the annonce behaviour ci thoec spring elements 13 or Of the ei eener shoe 1, are adapted appropriately, he an example, In this embodiment - - and in ail other embodiments - it as possible for the spring elements 13 to exhibit a different secant stiffness, i.e. for example, for the spring elements 13 with a larger spring element height 17 to hare a greater stiffness than the spring elements 13 with a smaller spring element height 17-With 3 variation of this type, it is possible, under normal loads, for damprng to be carried out by the spring elements 13 with the larger spring element height 17, and only under greater cads for the spring elements 13 with smaller spring element heights 17 to corse into effect- By adopting highly progressive spring characre r;sc r os, the spring elements 13 can be prov.eered from being overloaded, [QOhlj As can be seen in figure 11, in this embodiment the fillér 15 of the sleeper shoe 1 comes up to a spring element height 17 or slightly beyond it which is smaller than the maximum spring element height 17, [0052] As shown by the dashed lines in Figure 4, it is also possible for the entire gap 14 between spring elements 13 of equal heights to be filled· to the larger spring element height 17, .3)353j Figure 5 shows an embodiment of the sleeper shoe 1 in cross-section, in which the spring elements 13 again have different spring element heights 17, similar to that of Figure 4. In contrast to the embed men 1 of Figure 4, however, the smaller spring elements 13 are completely covered by the filler 15, so that essentially the sleeper 2 lies on a flat surface. This is particularly possible with the invention because, due to the filler IS, the spring characteristics of the spring elements 13, i,e. even that of the shorter spring elements, are not or arc substantially irssignifleantiy affected by the overlaid filler 15. (005¾] For rnis reason, in a further embodiment, shown as dashed lines in Figure 5, it is possible no cover all of thé spring elements 13 with the filler la in the horizontal direction, onereopen the ingress of water into the fleer region of the sleeper oies X can be sirXI farther reduced..

[Ö05S ] In order to produce the sleeper shoe X of the invention, the floor 9 and the lateral walls ID are prepared in a mould from an elastic material by means of vulcanization, This elastic material may, for example, be HR, SBR, EPOS, etc. A production process of this type rs already known in the art, and so there Is no need to make reference thereto hereire [OPSfi The spring elements 13 may be produced from the same substance in the mould used for the floor 9 and the lateral walls 10, On the other hand, it is possible for trie spring elements 13 to consist of another elastic material, whereupon these spring elements 13 are preferably vulcanized onto the surface of the floor S. fP0S7] In accordance with a first embodiment of the manufacturing method, an at least approximately flat plate is produced, from the second elastic material - as mentioned above - into which appropriate recesses of apertures are Introduced, for example by stssöping or cut ting, which correspond, to the geometry of the spiting elements 13, SO that after vuicaniration, this pro-prepared plate can be positioned on the spring elements 13, .:.. o. in the gaps 14.

[0058] in accordance with another variation of the method, the filler 15 can he foamed in situ, i.e., as an example, at the construction site, and to this end, a toamahle raw material is used for the filler 15, for example a s À r:g 1 o-oomponent or a two-001:000001 polyurethane. This raw material is introduced into the gaps 14, then the sleeper 2 is placed1 in the sleeper sane 1 and finally, the raw xnaterial for the filier If is üresed.· whereupon the gaps 14 sirs at least apnroxirra xsly conn ; ore ; y filled* [0059] Finally, it is also possible for the sleeper shoe 1 to foe produced ay what is known as a ts;o-eonponont net hod, in which the filler IS is injected, for example, into the paps 14 during vulcanisation of the sleeper shoe 1 and is loaned during vulcanisation, whereupon again, the gaps. 14 a.re at least approximately completely filled. The latter method has the advantage that the sleeper shoe can be produced in a single step, reducing the need for further a a send.; y steps, for example at the construction site. ; 00Of j The exemplary embedimentc indicate possible onbod i.men to of the sleeper shoe 1; it should be noted here that the invention is not limited, to the exemplary embed [merits thereof which have been described, but rather, various combinations of the individual exemplary embodiments are possible and these var rati one, because of the technical teaching: in the present invention, are within the purview of the person skilled in the art* Thus, any and all exemplary embodiments which may bo envisaged which are possible by combining individual details of the exemplary e mood :s men ts described and illustrated are included within the scope of the invention* [0061] Fins 1iy, for the sake of completion, it should be noted that for better bomprehehsion of the construction, the illustrations of the sleeper shoe 1 and/or its components have not always been drawn to scale and/or have been enlarged and/or reduced in site, [0062] The inventive subject matter of the present invention can he discerned from the description* [0063] Moreover, trie ereded i:ne:cr:> Indiested is.
