Durch diese Ausbildung kann der vorstehend angeführten Zielsetzung gut entsprochen werden. Es können die durch die Belastungen, die von denThe inventive track of the type mentioned above is characterized in that the elastomer profiles located in their interior and / or on its outside, extending over the longitudinal extent of these elastomer profiles and with the elastomeric material of these profiles intimately connected longitudinally stable reinforcing elements whose stiffness is greater than that of the elastomeric material , Through this training, the above-mentioned objective can be well met. It can be caused by the burdens of the
Eindeckelementen ausgeübt werden, verursachten Deformationen der Elastomerprofile, über den Querschnitt gesehen, vergleichmäßigt werden, wobei gleichzeitig auch eine Verminderung des Ausmaßes der Deformationen erzielt werden kann. Durch die Vergleichmäßigung der Deformationen wird auch der Sitz der Eindeckelemente an den Elastomerprofilen verbessert und die Vergleichmäßigung der Deformationen wirkt dem Entstehen von örtlichen Spannungsspitzen entgegen, welche an diesen Stellen zu einer Ermüdung des Gefüges Anlass geben können. Es kann erreicht werden, dass das elastische Verhalten der Elastomerprofile über längere Zeiträume weitgehend gleich bleibt und die betriebliche Lebensdauer dieser Profile, die durch ein Absinken der elastischen Eigenschaften und durch andere Verschleißerscheinungen bestimmt wird, eine Verlängerung erfährt.Covering elements are exerted, deformations of the elastomer profiles, seen over the cross section, are made uniform, while at the same time a reduction in the extent of the deformations can be achieved. By equalizing the deformations and the seat of the Eindeckelemente is improved on the elastomer profiles and the equalization of the deformations counteracts the emergence of local stress peaks, which can give rise to fatigue of the microstructure at these points.

Die bei der erfindungsgemäßen Ausbildung eines Gleises vorgenannter Art vorgesehenen Bewehrungselemente können aus verschiedenen Materialien bestehen, wobei insbesondere Metall und auch verschiedene Kunststoffmaterialien in Betracht kommen. Die Bewehrungselemente können vorzugsweise in vorgefertigter Form vorgesehen werden und mit vorgeformten Elastomerprofilen verbunden oder in diese eingebettet werden. Solche vorgeformte Bewehrungselemente können auch im Zuge der Formung von Elastomerprofilen in die Elastomerprofile eingebettet oder an diese Elastomerprofile angebettet werden. Eine Vorfertigung von Bewehrungselementen aus formbaren Massen, wie z.B. für eine Formgebung vorgesehenen Kunststoffmaterialien, kann in eigenen, nur für die Vorfertigung der betreffenden Bewehrungselemente dienenden Formen ausgeführt werden oder in Kombinationsformen, in denen in einem ersten Schritt die Vorfertigung von Bewehrungselementen vorgenommen wird und nachfolgend die Fertigung der Elastomerprofile erfolgt, wobei eine innige Bindung der Bewehrungselemente mit dem Elastomermaterial gebildet wird. Bei einer anderen Technik, welche insbesondere für die Bildung von an der Außenseite der Elastomerprofile vorzusehenden Bewehrungselementen gangbar ist, werden in einem ersten Schritt die Elastomerprofile geformt, wobei die für die Aufnahme der Bewehrungselemente vorgesehenen Raumbereiche ausgespart bleiben, und es werden in einem zweiten Schritt in die ausgesparten Bereiche formbare Massen eingebracht und zu Bewehrungselementen geformt und verfestigt, wobei dieser Prozess gegebenenfalls auch in Formen durchgeführt werden kann, in denen zuvor die Elastomerprofile geformt worden sind.The provided in the formation of a track of the aforementioned type of reinforcing elements may consist of different materials, in particular metal and also different plastic materials come into consideration.

Such preformed reinforcing elements can also be embedded in the elastomer profiles or embedded in these elastomer profiles in the course of forming elastomer profiles. Prefabrication of reinforcing elements from malleable masses, such as plastic materials intended for molding, may be carried out in separate molds used only for the prefabrication of the relevant reinforcing elements or in combination molds in which the prefabrication of reinforcing elements is carried out in a first step and subsequently the Production of the elastomer profiles is carried out, wherein an intimate bond of the reinforcing elements is formed with the elastomeric material. In another technique, which is particularly suitable for the formation of to be provided on the outside of the elastomeric profiles reinforcing elements, the elastomer profiles are formed in a first step, wherein the space provided for receiving the reinforcing elements space areas are left out, and it will be in a second step in the recessed areas introduced malleable masses and formed into reinforcing elements and solidified, which process may optionally also be carried out in forms in which previously the elastomer profiles have been formed.
Eine vorteilhafte Ausführungsform des erfindungsgemäß ausgebildeten Gleises ist dadurch gekennzeichnet, dass Eindeckelemente der Eindeckung tragende Elastomerprofile vorgesehen sind, die als Bewehrungselemente je eine Gruppe von über die Längserstreckung des jeweiligen Elastomerprofils verlaufenden Stäben aufweisen, die im Inneren des jeweiligen Elastomerprofils in dem zwischen der auf dem betreffenden Elastomerprofil aufliegenden Randzone eines Eindeckelements und der Oberseite des Schienenfußes, auf dem das betreffende Elastomerprofil aufliegt, gelegenen Bereich dieses Elastomerprofils mit gegenseitigem in Richtung der Quererstreckung des Schienenfußes gesehenen Abstand angeordnet sind. Es lässt diese Ausführungsform auf einfache Weise eine gute Formstabilität und auch eine Verringerung und Vergleichmäßigung der Deformationen, die durch die von den Eindeckelementen ausgeübten Belastungen entstehen, erzielen, was, wie vorstehend erwähnt, einen positiven Einfluss auf den Sitz der Eindeckelemente und auf die Lebensdauer der Elastomerprofile hat. Es kann dabei durch Wahl der Positionierungen der Stäbe in jenem Querschnittsbereich der Elastomerprofile, in dem der überwiegende Teil der von den Eindeckelementen ausgeübten Belastungen aufgenommen wird, eine Vergleichmäßigung der im Elastomermaterial wirkenden Spannungen erzielt werden, wobei bei der Positionierung der in Form von Stäben ausgebildeten Bewehrungselemente die Wahl der Abstände zwischen den genannten Stäben bedeutsam ist.An advantageous embodiment of the track according to the invention is characterized in that Eindeckelemente roofing elastomeric profiles are provided which have as reinforcing elements depending on a group of extending over the longitudinal extent of the respective elastomeric bars, which in the interior of the respective elastomeric profile in the between Elastomer profile resting edge zone of a Eindeckelements and the top of the rail foot on which rests the relevant elastomer profile, located region of this elastomeric profile with mutual seen in the transverse extension of the rail foot distance are arranged. It allows this embodiment in a simple manner, a good dimensional stability and also a reduction and equalization of the deformations caused by the forces exerted by the Eindeckelementen loads achieve, which, as mentioned above, a positive impact on the seat of Eindeckelemente and on the life of the Elastomer profiles has. It can be achieved by choosing the positions of the rods in that cross-sectional area of the elastomer profiles in which the majority of the loads exerted by the Eindeckelementen loads, a homogenization of the stresses acting in the elastomeric material can be achieved, wherein in the positioning of the reinforcing elements formed in the form of rods the choice of distances between said bars is significant.
Eine vereinfachte Variante zur vorgenannten Ausführungsform ist dadurch gekennzeichnet, dass Eindeckelemente der Eindeckung tragende Elastomerprofile vorgesehen sind, die im Inneren des jeweiligen Elastomerprofils in dem zwischen der auf dem betreffenden Elastomerprofil aufliegenden Randzone eines Eindeckelements und der Oberseite des Schienenfußes, auf dem das betreffende Elastomerprofil aufliegt, gelegenen Bereich dieses Elastomerprofils als Bewehrungselement mindestens eine über die Längserstreckung des jeweiligen Elastomerprofils verlaufende streifenförmige Platte, deren Breitenerstreckung in Richtung der Quererstreckung des Schienenfußes verläuft, aufweisen.A simplified variant of the aforementioned embodiment is characterized in that Eindeckelemente roofing elastomeric profiles are provided which in the interior of the respective elastomer profile in between the resting on the respective elastomeric edge zone of a Eindeckelements and the top of the rail foot on which rests the relevant elastomer profile lying region of this elastomeric profile as a reinforcing element at least one over the longitudinal extent of the respective elastomeric profile extending strip-shaped plate whose width extension in the direction of Transverse extent of the rail foot extends, have.
Eine Ausführungsform, welche insbesondere für ein Geringhalten an der Oberfläche der Elastomerprofile auftretender Verschleißerscheinungen Vorteile bietet, wobei ein Verschleiß, der an den Berührungsstellen der Eindeckelemente mit den Elastomerprofilen auftritt, weitgehend vermindert werden kann, ist dadurch gekennzeichnet, dass Eindeckelemente der Eindeckung tragende Elastomerprofile vorgesehen sind, die an ihrem nach oben weisenden Oberflächenbereich, an dem ein Eindeckelement mit seiner Randzone aufliegt, als Bewehrungselement eine über die Längserstreckung des jeweiligen Elastomerprofils verlaufende streifenförmige, mit dem Elastomermaterial des Elastomerprofils innig verbundene Platte aufweisen.An embodiment which offers advantages in particular for low wear occurring on the surface of the elastomer profiles, wherein a wear that occurs at the points of contact of the Eindeckelemente with the elastomer profiles, can be largely reduced, is characterized in that Eindeckelemente the roofing load-bearing elastomer profiles are provided having on its upwardly facing surface area, on which a flashing element rests with its edge zone, as a reinforcing element over the longitudinal extent of the respective elastomeric profile extending strip-shaped, intimately connected to the elastomeric material of the elastomeric profile plate.
Hinsichtlich einer Verminderung von Verschleißerscheinungen an den Berührungsstellen der Elastomerprofile mit den Schienen ist es vorteilhaft, wenn man vorsieht, dass Eindeckelemente der Eindeckung tragende Elastomerprofile vorgesehen sind, die an dem nach unten weisenden Oberflächenbereich, an dem das betreffende Elastomerprofil auf dem Schienenfuß aufliegt, als Bewehrungselement eine über die Längserstreckung des jeweiligen Elastomerprofils verlaufende streifenförmige, mit dem Elastomermaterial des Profils innig verbundene Platte aufweisen.With regard to a reduction of signs of wear at the points of contact of the elastomer profiles with the rails, it is advantageous to provide covering elements for the roofing-carrying elastomeric profiles, which serve as a reinforcing element on the downwardly facing surface area on which the relevant elastomeric profile rests on the rail foot have over the longitudinal extent of the respective elastomeric profile extending strip-shaped, with the elastomeric material of the profile intimately connected plate.
Das vorgenannte Vorsehen von Bewehrungselementen im Oberflächenbereich der Elastomerprofile kann vorteilhaft auch mit dem oben erwähnten Vorsehen von Bewehrungselementen im Inneren der Elastomerprofile kombiniert werden.The aforementioned provision of reinforcing elements in the surface region of the elastomer profiles can advantageously also be combined with the above-mentioned provision of reinforcing elements in the interior of the elastomer profiles.
Hinsichtlich der Ausbildung von, wie vorerwähnt, im Oberflächenbereich der Elastomerprofile vorgesehenen Bewehrungselementen ist es weiter vorteilhaft, wenn man vorsieht, dass über die Längserstreckung der jeweiligen Elastomerprofile verlaufend angeordnete Platten abgewinkelt geformt sind, wobei die geometrische Linie der Abwinkelung in Längsrichtung des jeweiligen Elastomerprofils verläuft. Es kann auf diese Weise der Übertragung von Seitenführungskräften, welche außer den von den Eindeckelementen ausgeübten Gewichtsbelastungen auf die Elastomerprofile einwirken, im Sinne einer Verminderung der im Elastomermaterial auftretenden Spannungen entsprochen werden, und auch eine verschleißmindernde Anpassung an die jeweils vorliegende Form des Schienenfußes erhalten werden.With regard to the formation of, as mentioned above, provided in the surface region of the elastomer profiles reinforcing elements, it is also advantageous if it is provided over the longitudinal extension of the respective elastomer profiles extending plates are formed angled, wherein the geometric line of the bend extends in the longitudinal direction of the respective elastomer profile. It can in this way the transmission of cornering forces, which act in addition to the weight loads exerted by the Eindeckelementen on the elastomer profiles, in Sense of a reduction of the stresses occurring in the elastomeric material are met, and also a wear-reducing adaptation to the respective present form of the rail foot can be obtained.
Eine weitere vorteilhafte Ausführungsform des Erfindungsgegenstandes ist dadurch gekennzeichnet, dass die Elastomerprofile, welche die Eindeckelemente tragen, in den Bereichen zwischen in Gleislängsrichtung aufeinanderfolgend angeordneten Schienenbefestigungselementen, mit denen die Schienen des Gleises auf Schwellen befestigt sind, platziert sind, und dass in dem zwischen den beiden Schienen des Gleises befindlichen Mittenbereich des Gleises Abdeckelemente, welche die Schienenbefestigungselemente überdecken, über den Schienenbefestigungselementen sitzend angeordnet sind, wobei die in diesem Mittenbereich befindlichen Eindeckelemente tragenden Elastomerprofile mit ihren Endflächen an den Abdeckelementen zur Anlage kommen. Es kann solcherart die Handhabung beim Einbau der die Eindeckelemente tragenden Elastomerprofile vereinfacht werden und eine Berücksichtigung der am Schienenfuß angreifenden Schienenbefestigungselemente durch entsprechende Formung der Elastomerprofile an dieser Stelle erübrigt werden; letzteres erscheint gerade im Zusammenhang damit, dass die genannten Elastomerprofile längsstabile Bewehrungselemente aufweisen, bedeutsam. Durch die über den Schienenbefestigungselementen sitzenden Abdeckelemente wird die Handhabung beim Einbau der Elastomerprofile erleichtert und auch ein guter Schutz der Schienenbefestigungselemente gegenüber nachteiligen äußeren Einflüssen erzielt.A further advantageous embodiment of the subject invention is characterized in that the elastomer profiles which carry the Eindeckelemente, in the areas between track longitudinally successively arranged rail fasteners, with which the rails of the track are mounted on sleepers, and that in between the two Rails of the track located central region of the track covering elements which cover the rail fastening elements are arranged sitting over the rail fastening elements, wherein the Eindeckelemente in this central region carrying elastomer profiles come with their end faces on the cover elements to the plant. It can be simplified in such a way handling the installation of the Eindeckelemente supporting elastomer profiles and a consideration of engaging the rail foot rail fasteners are made unnecessary by appropriate shaping of the elastomer profiles at this point; The latter appears to be significant in connection with the fact that said elastomer profiles have longitudinally stable reinforcing elements. By sitting over the rail fastening elements covering the handling of the installation of the elastomer profiles is facilitated and also achieved a good protection of the rail fastening elements against adverse external influences.

Die in den seitlichen Ausnehmungen 8 der Schienen 4 angeordneten, die Eindeckelemente 2 tragenden Elastomerprofile 7a, 7b weisen in ihrem Inneren 11 längsstabile Bewehrungselemente 14 auf, welche über die Längserstreckung 13 dieser Profile 7a, 7b verlaufen und mit dem Elastomermaterial dieser Profile innig verbunden sind. Die Steifigkeit dieser Bewehrungselemente, welche in diesem dargestellten Fall in Form von Rundstäben ausgeführt sind, ist größer als die Steifigkeit des Elastomermaterials der Elastomerprofile 7a, 7b. Die die Bewehrungselemente 14 bildenden Stäbe können auch andere Querschnittsformen haben. Es sind diese Bewehrungselemente 14 in jenem Bereich 19 der Elastomerprofile 7a, 7b angeordnet, der zwischen der auf dem betreffenden Profil 7a, 7b aufliegenden Randzone 6 des jeweiligen Eindeckelementes 2 und der Oberseite 18 des Schienenfußes 17 der betreffenden Schiene 4 liegt. Die Bewehrungselemente 14 sind mit gegenseitigem Abstand 21, in Richtung 20 der Quererstreckung des Schienenfußes 17 gesehen, angeordnet. Durch entsprechende Wahl der Größe dieser Abstände 21 kann das Ausmaß der Deformation, die sich durch die Belastung der Elastomerprofile mit den Eindeckelementen 2 ergibt, und auch die Elastizität der Elastomerprofile beeinflusst werden.The arranged in the
