Description

  The present invention is a track having a cover formed of a thick plate-like cover member, wherein the upper surface of the cover member constitutes a passage surface extending the same height as the rails of the track, and the cover member is a track The track is supported only at the rail of the track, in the peripheral edge facing the rail, engaged with the side recess of the rail via an elastomeric profile.

  In a track of the kind described above, the attachment of a cover element constituting the passage surface is advantageous for retaining the dynamic nature of the track in the area of the cover, and furthermore for performing the work necessary for the maintenance of the track. It will be very advantageous. Also, the attachment of such a cover member has advantageous characteristics with regard to realizing the sound absorption behavior of the track.

  The object of the present invention is to extend the service life of the elastomeric profile supporting the cover on the rail and to ensure that the elastic properties of the elastomeric profile do not change over as long as possible. Further improve the attachment properties of the cover member in the railway track.

  According to the invention, a track of the type mentioned at the outset is arranged in the side recess of the rail and provided with an elastomeric profile (Elastomer profile) supporting the cover member on at least one of the inner and outer surfaces of the elastomeric profile, With a longitudinal stiffening member, the stiffening member extends over the longitudinal extension of the elastomeric profile and bonds intimately to the elastomeric material of the profile so that the stiffness of the stiffening member is increased. , Is characterized by being higher than the rigidity of the elastomeric material. Such an arrangement sufficiently achieves the above-mentioned object. The deformation of the elastomeric profile due to the load applied from the cover member can be homogenized over its cross section, and at the same time the amount of deformation can be reduced. The homogenization of the deformation also improves the seating (Sitz) of the cover member on the elastomeric profile and prevents the occurrence of local stress peaks which may cause structural fatigue at that location. Become. It makes it possible to keep the elastic behavior of the elastomeric profile material constant over time and to extend the service life of the profile material, which is determined by the deterioration of the elastic properties and other wear phenomena .

  The reinforcement elements provided in the arrangement according to the invention of the kind of line described above may be made of various materials, in particular metals or even various synthetic materials can be taken into account. The reinforcing member may preferably be provided in a manufactured form and may be bonded or embedded in a preformed elastomeric profile. Such pre-formed reinforcement members can be embedded in or attached to the elastomeric profile during molding of the elastomeric profile. The pre-manufacture of reinforcement members from moldable masses, such as eg plastic materials provided for molding, can be carried out in special molds only for prefabricating reinforcement members or in composite moulds It is possible. In the composite mold, in a first step, the reinforcing member is prefabricated, and then the reinforcing member and the elastomeric material are closely bonded to produce an elastomeric profile. Another approach that is particularly practical for the formation of reinforcing members on the outer surface of the elastomeric profile material is that in a first step, the elastomeric profile material is formed with empty areas provided to receive the reinforcing member. And, in the second step, a moldable mass is introduced into the void area, formed into a reinforcing material and solidified, if necessary, this process is performed by using a gold on which an elastomeric profile material has been previously molded. It may be implemented in a type.

  An advantageous embodiment of the line according to the invention is characterized in that the elastomeric profile supporting the cover element of the cover comprises, as reinforcement elements, a plurality of rods extending over the longitudinal extension of the elastomeric profile. Elastomeric material, wherein the rod is located inside the elastomeric profile material, between the peripheral edge of the cover member placed on the elastomeric profile material and the upper surface of the rail foot on which the elastomeric profile material is placed It is characterized in that in the area of the profile material, they are spaced from one another in the direction of the lateral extension of the rail legs. This simple embodiment not only provides good dimensional stability but also reduces and homogenizes the deformation due to the load applied from the cover member, which, as described above, It will have a positive effect on the seating and the service life of the elastomeric profile. By selecting the position of the rods in the cross-sectional area of the elastomeric profile where the majority of the load applied from the cover member is absorbed, the stresses acting on the elastomeric material will be homogenized and the spacing of the rods The choice is important for the positioning of the reinforcing element configured in the form of a rod.

  A simplified variant of the embodiment described above is that the elastomeric profile supporting the cover member of the cover is at least one strip-like plate extending over the longitudinal extension of the elastomeric profile as a reinforcing member, wherein The widthwise extension of the plate comprises at least one strip-shaped plate extending in the direction of the lateral extension of the rail foot, wherein the at least one strip-shaped plate is the interior of the elastomeric profile and the elastomeric profile It is characterized in that it is disposed in a region of the elastomeric profile material located between the peripheral edge of the cover member placed on the material and the upper surface of the rail leg on which the elastomeric profile material is placed.

  An embodiment which provides a particular advantage with regard to suppressing the wear phenomena occurring on the surface of the elastomeric profile while significantly reducing the wear occurring at the contacts between the cover and the elastomeric profile is the cover of the cover. The supporting elastomeric profile has a strip-like plate as a stiffening member on the upward facing surface area, the cover member is mounted on the upward facing surface area by the peripheral edge, and the strip-like plate is an elastomeric profile It is characterized in that it extends over the longitudinal extension and is intimately connected to the elastomeric material of the elastomeric profile.

  An elastomeric profile supporting the cover member of the cover is mounted on the rail foot in the downward surface area for the purpose of reducing the wear phenomena at the contact between the elastomeric profile and the rail Advantageously, on the downward surface area, it is advantageous if it has a strip plate as a reinforcing element, the strip plate extending over the longitudinal extension of the elastomeric profile and being intimately connected to the elastomeric material of the profile. I will.

  Providing a reinforcing member in the surface area of the elastomeric profile in this manner is also advantageous in combination with providing the reinforcing member inside the elastomeric profile described above.

  As described above, with regard to the configuration of the reinforcing members provided in the surface area of the elastomeric profile, the plate arranged to extend over the longitudinal extension of the elastomeric profile is configured to be abgewinkelt It would be further advantageous if the geometrical lines of the construction extend in the longitudinal direction of the elastomeric profile. Thus, the transmission of the lateral guiding force (Seitenfuehrungskraeften) acting on the elastomeric profile together with the weight load applied from the cover member is permitted in terms of reducing the stresses generated in the elastomeric material, and providing the rail legs Adaptation to reduce wear to the shape will also be achieved.

  A further advantageous embodiment of the subject matter of the present invention is the area between the longitudinally arranged rail fastening members of the track, in which the elastomeric profile supporting the cover members secures the rails of the track to the tie. And a covering member for covering the rail fixing member is disposed in the central region so as to straddle above the rail fixing member in the central region of the line located between the two rails of the track. An elastomeric profile supporting the cover member is characterized in that it is adjacent to the covering member at its end face. Thus, the handling when attaching the elastomeric profile supporting the cover member is simplified. In addition, by appropriately configuring the elastomeric profile at this position, it is not necessary to consider the rail fixing member engaged with the rail leg, which means that the elastomeric profile described above is stable in the longitudinal direction. It appears to be of great importance in connection with having a reinforcing member. The covering member straddling the upper side of the rail fixing member facilitates handling when attaching the elastomeric profile member, and the rail fixing member is well protected from external adverse effects.
