Description

  The present invention is a track having a cover composed of a thick plate-like cover member, wherein the upper surface of the cover member constitutes a passing surface extending the same height as the rail of the track, and the cover member is a track It is related with the track | line which is supported only by the rail of a track | line in the state engaged with the side surface recessed part of the rail through the elastomer profile material in the peripheral part facing the rail.

  In the type of track described above, attaching a cover member that constitutes the passage surface is advantageous for maintaining the dynamic properties of the track in the area of the cover, and further performing work necessary for track maintenance. This is a great advantage. In addition, the attachment of such a cover member has advantageous characteristics with respect 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 material supporting the cover member on the rail and to prevent the elastic properties of the elastomeric profile material from changing over as long as possible. It is to further improve the properties relating to the attachment of the cover member in the line.

  According to the present invention, a track of the kind described at the beginning is arranged in a side recess of a rail, and an elastomer profile material (Elastomerprofile) supporting a cover member is provided on at least one of the inside and the outer surface of the elastomer profile material, A longitudinally stable reinforcement member, the reinforcement member extending over the longitudinal extension of the elastomeric profile material and innig bonding to the elastomeric material of the profile material so that the stiffness of the reinforcement member is It is characterized by being higher than the rigidity of the elastomer material. With such a configuration, the above-described object is sufficiently achieved. The deformation of the elastomeric profile material 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 of the cover member on the elastomeric profile (Sitz) and prevents the occurrence of local stress peaks (Spannungsspitzen) that can cause structural fatigue at that location. Become. It is feasible that the elastic behavior of the elastomeric profile material is kept almost constant over a long period of time and that the operating life of the profile material is extended, which is determined by the deterioration of the elastic properties and other wear phenomena. .

  Reinforcing members provided in the configuration according to the invention of the above-mentioned types of lines can be composed of various materials, in particular even metals and various synthetic materials can be taken into account. The reinforcing member may preferably be provided in a manufactured form and may be bonded to or embedded in a preformed elastomeric profile material. Such a preformed reinforcing member can be embedded or attached to the elastomeric profile material during the molding of the elastomeric profile material. Pre-manufacturing of the reinforcing member from a moldable mass, for example a plastic material provided for molding, can be performed in a special mold only for pre-manufacturing the reinforcing member or in a composite mold Is possible. In the composite mold, the reinforcing member is manufactured in advance in the first stage, and then the reinforcing member and the elastomer material are intimately bonded to manufacture an elastomer profile material. Another approach that is particularly practical for the formation of a reinforcing member provided on the outer surface of an elastomeric profile material is to form an elastomeric profile material in the first stage with the empty space provided for receiving the reinforcing member remaining empty. In the second stage, a moldable mass is introduced into the empty area and formed into a reinforcing material and solidified, but if necessary, this process can be carried out using a previously molded elastomer profile material. May be performed on a type.

  According to an advantageous embodiment of the track according to the invention, the elastomeric profile material supporting the cover member of the cover has a plurality of bars extending as a reinforcing member over the longitudinal extension of the elastomeric profile material, The rod is inside the elastomer profile material and is made of an elastomer positioned between the peripheral edge of the cover member placed on the elastomer profile material and the upper surface of the rail leg on which the elastomer profile material is placed. In the region of the profile material, the rail legs are arranged at intervals in the direction of the lateral extension of the rail legs. This simple embodiment not only provides good dimensional stability, but also reduces deformation and homogenization due to the load applied from the cover member, which, as mentioned above, It will have a positive impact on the seating and the useful life of the elastomeric profile material. By selecting the position of the rods in the cross-sectional area of the elastomeric profile material where most of the load applied from the cover member is absorbed, the stress acting on the elastomeric material will be homogenized and the spacing of the rods will be reduced. The choice is important for the positioning of the reinforcing member configured in the form of a bar.

  In a simplified variant of the above-described embodiment, the elastomeric profile material supporting the cover member of the cover is at least one belt-like plate extending as a reinforcing member over the longitudinal extension of the elastomeric profile material, The widthwise extension of the plate has at least one strip plate extending in the direction of the lateral extension of the rail leg, the at least one strip plate being inside the elastomeric profile material, the elastomeric profile It is characterized in that it is arranged in the region of the elastomer profile material located between the peripheral edge portion of the cover member placed on the material and the upper surface of the rail leg portion on which the elastomer profile material is placed.

  An embodiment that provides particular advantages with respect to suppressing the wear phenomenon that occurs on the surface of the elastomeric profile material while greatly reducing the wear that occurs at the contact point between the cover member and the elastomeric profile material is a cover member of the cover. The supporting elastomer profile material has a strip-shaped plate as a reinforcing member on the upward surface region, the cover member is placed on the upward surface region by the peripheral portion, and the strip plate is made of the elastomer profile material. It extends over the longitudinal extension and is closely connected to the elastomeric material of the elastomeric profile material.

  In order to reduce the wear phenomenon at the contact point between the elastomer profile material and the rail, the elastomer profile material supporting the cover member of the cover is placed on the rail leg in the downward surface area. In addition, it is advantageous if it has a strip plate as a reinforcing member on the downward surface area, the strip plate extends over the longitudinal extension of the elastomeric profile material and is closely bonded to the elastomeric material of the profile material. I will.

  Providing the reinforcing member in the surface region of the elastomer profile material in this way is advantageous in combination with the above-described provision of the reinforcement member inside the elastomer profile material.

  As described above, with respect to the configuration of the reinforcing member provided in the surface region of the elastomeric profile material, the plate arranged to extend over the longitudinal extension of the elastomeric profile material is configured to be abgewinkelt and squared. It would be further advantageous if the geometric line of this configuration extends in the longitudinal direction of the elastomeric profile material. In this way, the transmission of side guide forces (entsprochen) acting on the elastomeric profile material together with the weight load applied from the cover member is allowed (entsprochen) in terms of reducing the stress generated in the elastomeric material, giving the rail legs Adapting to reduce wear for the shape formed will also be achieved.

  A further advantageous embodiment of the inventive subject matter is that the area between the rail fixing members arranged continuously in the longitudinal direction of the track, in which the elastomeric profile material supporting the cover member fixes the rail of the track to the sleepers In the central region of the track located between the two rails of the track, a covering member that covers the rail fixing member is disposed so as to straddle the rail fixing member, and is provided in the central region. An elastomer profile material that supports the cover member is adjacent to the covering member at its end face. In this way, handling when attaching the elastomer profile material that supports the cover member is simplified. In addition, by properly configuring the profile member made of elastomer at this position, it is not necessary to consider the rail fixing member that engages with the rail leg, which means that the above-described elastomer profile member is stabilized in the longitudinal direction. It seems to be just as important in connection with having a reinforcing member. The covering member straddling the upper side of the rail fixing member facilitates handling when attaching the elastomer profile material, and further, the rail fixing member is well protected from external adverse effects.
