Description

[0001] The present invention relates to an angle guide plate according to the preamble of claim 1. Technological background

[0002] A track forms the track for railways and comprises a superstructure and a substructure. The superstructure includes rails, sleepers, a rail fastening system, and a track bed. The function of the superstructure is to maintain the track gauge and transfer the existing forces into the substructure.

[0003] The rail fastening system has a tension clamp, an angled guide plate, and a sleeper screw on both sides of the rail in the sleeper area. One side of the angled guide plate rests against the rail foot, and on the opposite side, its sleeper stop web, which is designed as a bead-shaped engagement area, engages in a sleeper groove. The tension clamp is positioned so that it rests on both the rail foot and the angled guide plate. It is anchored in the sleeper via a sleeper screw. The tension clamp is pressed into a bead in the angled guide plate and onto the rail foot, thereby fixing the rail to the sleeper. Forces that arise, in particular when a train passes over, are transferred into the sleeper and the railway substructure via the angled guide plate.

[0004] Angled guide plates must withstand and reliably transmit considerable forces. Therefore, angled guide plates have relatively thick walls and, consequently, high material requirements. Angled guide plates are typically manufactured using an injection molding process and, due to their thick walls, have relatively long cooling times. Therefore, long production cycle times are required for the manufacture of angled guide plates. Furthermore, angled guide plates have a significant carbon footprint due to the production cycle time and the high material usage. Printed state of the art

[0005] From G 87 06 640.8, an angled guide plate according to the preamble of claim 1 is known. In this angled guide plate, recesses are formed in the angled outer surface and in the area of ​​the base surface. The recesses formed in the angled outer surface open into the top side of the angled guide plate. The recesses formed in the angled outer surface and in the area of ​​the base surface are each distributed at equal distances along the underside and outer surface, respectively. The recesses serve to compensate for unevenness and simultaneously save material.

[0006] EP 0 767 274 B1 discloses an angled guide plate in which recesses are provided on both sides of the through hole, distributed at equal distances along the underside or outer surface. Only a space corresponding to the diameter of the through hole is provided between them. Object of the present invention

[0007] The object of the present invention is to provide an angle guide plate with optimized force introduction while simultaneously saving material. Solution to the task

[0008] The above-mentioned task is achieved by applying force to the sleeper via the contact webs located on the underside opposite the bead only at the respective edge area of ​​the angled guide plate. Due to the special force application only at the edge area, the angled guide plate rests firmly on the sleeper even on uneven surfaces. At the same time, a significant material saving can be achieved compared to the state of the art. This, in turn, leads to a considerable reduction in the carbon footprint.

[0009] According to an advantageous embodiment of the invention, the force can be introduced into the respective edge area of ​​the angled guide plate onto the sleeper via contact webs arranged in pairs in the respective edge area of ​​the angled guide plate. This allows the strength of the respective edge area of ​​the angled guide plate to be optimized despite material savings.

[0010] According to an advantageous embodiment of the invention, an elongated recess in the floor can extend between the force introduction point of one edge region and the force introduction point of the opposite edge region. This allows for considerable material savings. At the same time, unevenness on the sleeper or contamination, e.g., from material washed in, does not affect the angle guide plate in this area. The floor recess is dimensioned larger in its extension between the two edge regions than the diameter of the through hole for the sleeper screw.

[0011] According to an advantageous embodiment of the invention, the contact webs arranged in pairs in the respective edge region of the angle guide plate can be separated from one another by a floor recess located in the edge region.

[0012] According to an advantageous embodiment of the invention, the sleeper stop web can have recesses on its laterally inclined sleeper stop surface to save material.

[0013] According to an advantageous embodiment of the invention, a plurality of recesses can be formed adjacently into the sleeper stop surface above the internal floor recess. This can result in significant material savings and thus a considerable reduction in the CO2 footprint.

[0014] According to an advantageous embodiment of the invention, at least one recess can be formed above the two paired contact webs in the sleeper stop surface. This also contributes to material savings.

[0015] According to an advantageous embodiment of the invention, a longitudinal web extending in the longitudinal direction of the rail can be provided in the sleeper stop surface between the upper side of the sleeper stop web and the upper side of the respective recess and / or between the underside of the sleeper stop web and the underside of the respective recess. This supports the contact behavior and the force transmission from the angle guide plate into the sleeper despite the high degree of material savings of the invention.

[0016] According to an advantageous embodiment of the invention, the respective recess can have a square, preferably trapezoidal outline.

[0017] According to an advantageous embodiment of the invention, the respective recess can have, at least partially, rectilinear inner walls, in particular those extending at an angle to one another. These walls can preferably be designed with an orientation inclined toward one another toward the inside of the recess, which facilitates demolding of the angled guide plate from the mold.

[0018] According to an advantageous embodiment of the invention, the sleeper stop web can have a material web in the area of ​​the position of the underside contact webs that runs continuously from the top to the bottom of the sleeper stop web without a recess. This ensures effective force transmission with sufficient mechanical stability despite the high degree of material savings.

[0019] According to an advantageous embodiment of the invention, the continuous material web without a recess can be an outer material web or an inner, i.e., slightly more inwardly located, material web. In a paired arrangement, both the outer and inner material webs are designed as a continuous material web, i.e., as a single material web without a recess.

[0020] According to an advantageous embodiment of the invention, the respective inner material web along the angle guide plate in the track direction can be assigned, at least substantially, in its position to the respective contact pressure area for the tension clamp on the bead of the angle guide plate.

[0021] According to an advantageous embodiment of the invention, the angle guide plate can be an injection-molded part, preferably a plastic injection-molded part. Description of the invention using an embodiment

[0022] Expedient embodiments of the present invention are explained in more detail using examples in the drawing figures. For the sake of clarity, recurring features are provided with a reference numeral only once. They show: Fig. 1 a perspective view of an angle guide plate according to the invention in an installed state; Fig. 2 a partial sectional view of the arrangement according to Fig. 1; Fig. 3 a perspective view of an example of the angle guide plate in the installation according to Fig. 1 and 2; Fig. 4 a plan view of the top of the angle guide plate of Fig. 3; Fig. 5 a sectional view along the section AA of Fig. 4; Fig. 6 a sectional view along the section surface BB of Fig. 4; Fig. 7 a side view of the angle guide plate according to Fig. 3; and Fig. 8 a plan view of a front side area of ​​the angle guide plate according to Fig. 3.

[0023] Fig. 1 shows an example of the installation of a rail 200 on a sleeper 100, for example, a concrete sleeper or plastic sleeper, using an angled guide plate 300 according to the invention. The angled guide plate 300 is located between the rail foot 201 and a raised portion 105 on the upper side of the sleeper 100. On the side of the raised portion 105 facing the rail 200, a sleeper groove 101 is formed in the sleeper 100, into which the angled guide plate 300 engages and fixes it in position. The other side of the angled guide plate 300 also rests against the stop web 202 of the rail foot 201. The opposite side of the angled guide plate 300 rests against the raised portion 105 of the sleeper 100.

[0024] A spring-loaded tension clamp 103 is fixed to the upper side of the angle guide plate 300 via a sleeper screw 102 in such a way that the tension clamp 103 rests on the one hand on the rail foot 201 of the rail 200 and on the other hand on a bead 305 of the angle guide plate 300, as can be seen from Fig. 2. The angle guide plate 300 forms a stop web 301 to the stop web 202 of the rail foot 201. As can be seen from Fig. As can be seen in Figure 2, the angle guide plate 300 is thus clamped between the elevation 105 of the sleeper 100 and the rail foot 201 of the rail 200 and fixed by means of the tension clamp 103. The tension clamp 103 rests against the upper side of the rail foot 201 and the upper side of the angle guide plate 300.

[0025] An intermediate layer 104 is arranged between the rail 200 and the sleeper 100 for damping purposes.

[0026] Although in the Fig. 1 and Fig. 2 a corresponding arrangement is shown only on one side of the rail 200 for the sake of clarity, a corresponding arrangement is located on both sides of the rail 200.

[0027] The angled guide plate 300 is a molded part, which is produced in particular by injection molding, preferably from plastic. The angled guide plate 300 has, according to Fig. 3, a bottom side 317 associated with the sleeper 100, as well as an opposite top side 318. It has a base 309, on one side of which the stop web 301 is provided, which forms a rail foot stop surface 310. On the opposite side, a sleeper stop web 303 is formed, which has a bead-like shape and on its underside fits into the sleeper groove 101, cf. Fig. 2, fits well with its oblique lateral threshold stop surface 304 against the elevation 105 of the threshold 100.

[0028] The lateral sleeper stop surface 304 has an outer recess 306 on both edge areas and several inner recesses 307 between them. Support webs 319, 320 are formed in the lower area of ​​the sleeper stop web 303. On the opposite side, the bead 305 is formed into the base 309 of the angle guide plate 300 and serves to form a support surface for the tension clamp 103. A step 313 can be provided in the area of ​​the stop web 301 to accommodate part of the intermediate layer 104.

[0029] In the central area there is a through hole 302 for receiving the sleeper screw 102. The base 309 of the angle guide plate 300 has a raised portion 311 in the area of ​​the through hole 302. The reference number 308 designates the sprue.

[0030] In Fig. 4 shows the contact pressure areas 321 of the tension clamp 103 in the groove 305. This is where the greatest contact pressure is applied to the angle guide plate 300 via the tension clamp 103.

[0031] Fig. 5 shows a cross section through the angle guide plate 300 of Fig. 4 along section plane AA. The material savings achieved by the presence of the internal recesses 307 and the internal floor recess 312 are clearly visible.

[0032] Fig. 6 shows a slight decrease in the thickness of the base 309 starting from the through hole 302 towards the respective end of the angle guide plate 300.

[0033] According to Fig. 7, a force introduction F1, F2 onto the sleeper 100 takes place via the contact webs 319, 320 located on the underside only in the opposite edge regions B1, B2 of the angled guide plate 300, viewed in the direction of the rail 200. For this purpose, the force introduction F1, F2 in the respective edge region B1, B2 of the angled guide plate 300 onto the sleeper 100 can take place via contact webs 319, 320 arranged in pairs in the respective edge region B1, B2 of the angled guide plate 300.

[0034] An elongated internal floor recess 312 extends between the force introduction point F1 of one edge region B1 and the force introduction point F2 of the opposite edge region B2. This allows for considerable material savings. The paired landing bridges 319, 320 are separated from each other by a floor recess 314 located in the respective edge region B1, B2.

[0035] Above the inner floor recess 312, several recesses 307 are formed next to one another in the sleeper stop surface 304. Likewise, a recess 306 is formed in the sleeper stop surface 304 between each of the two paired contact webs 319, 320.

[0036] The recesses 306, 307 are bordered on all sides, ie they do not open into the upper surface or lower surface of the angle guide plate 300. Between the upper side of the sleeper stop web 303 and the upper side of the respective recess 306, 307 as well as between the underside of the sleeper stop web 303 and the underside of the respective recess 306, 307, an upper or lower longitudinal web 315, 316 is provided which is continuous in the direction of the extension of the rail 200.

[0037] The respective recess 306, 307 can have, at least partially, rectilinear, in particular mutually angular, inner walls, preferably with an orientation inclined towards one another towards the inner side of the recess 306, 307.

[0038] The sleeper stop web 303 forms in the area of ​​the contact webs 319, 320 a continuous material web 322, 323 from the top side 318 to the bottom side 317 of the sleeper stop web 303 without a recess therein. According to Fig. 7, there is a continuous outer material web 322 in the outer area and the further continuous inner material web 323 within the respective outer recess 306 and the adjacent inner recess 307. Via the material webs 322, 323, the force can be optimally transmitted via the angle guide plate 300 to the sleeper 100.

[0039] In this case, the inner material web 323 can be assigned, at least substantially, to the position of the contact pressure area 321 for the tension clamp 103.

[0040] Preferably, the angle guide plate 300 is an injection-molded part, preferably a plastic injection-molded part.

[0041] The present invention ensures improved force transmission into a sleeper while simultaneously saving considerable material. The present invention of an angled guide plate thus represents a significant advance in the relevant field of technology.
