Description

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

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

[0003] The rail fastening system features a clamping 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, while the opposite side engages a sleeper groove with its bead-shaped engagement flange. The clamping clamp is positioned so that it rests on both the rail foot and the angled guide plate. It is anchored in the sleeper by a sleeper screw. This action presses the clamp into a groove in the angled guide plate and onto the rail foot, thus fixing the rail to the sleeper. Forces, particularly those generated by passing trains, are transferred via the angled guide plate into the sleeper and then into the track bed.

[0004] Angle guide plates must withstand high forces and reliably transmit them. Therefore, angle guide plates have relatively thick walls and consequently require a high amount of material. Angle guide plates are typically manufactured using injection molding and, due to their thick walls, have relatively long cooling times. This results in long production cycle times for their manufacture. Furthermore, due to the production cycle time and high material consumption, angle guide plates have a significant CO₂ footprint. Printed state of the art

[0005] From German patent application 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 surface of the angled guide plate. The recesses formed in the angled outer surface and in the area of ​​the base surface are arranged at equal intervals along the underside and outer surface, respectively. The recesses serve to compensate for unevenness and simultaneously save material.

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

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

[0008] The aforementioned problem is solved by applying force to the threshold only in the respective edge area of ​​the angled guide plate via the contact ribs located on the underside opposite the groove. Due to this specific, edge-only force application, the angled guide plate rests securely on the threshold even on uneven surfaces. At the same time, a significant material saving can be achieved compared to the prior art. This, in turn, leads to a considerable reduction in the CO₂ footprint.

[0009] According to an advantageous embodiment of the invention, the force can be introduced onto the threshold in the respective edge region of the angled guide plate via contact ribs arranged in pairs in the respective edge region of the angled guide plate. This allows the strength of the respective edge region 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 application point of one edge region and the force application point of the opposite edge region. This allows for considerable material savings. At the same time, unevenness on the threshold or contamination, e.g., from washed-in material, does not affect the angle guide plate in this area. The floor recess is dimensioned larger in its extent between the two edge regions than the diameter of the through-hole for the threshold screw.

[0011] According to an advantageous embodiment of the invention, the support ribs arranged in pairs in the respective edge region of the angle guide plate can be separated from each other by a floor recess located in the edge region.

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

[0013] According to an advantageous embodiment of the invention, a plurality of recesses can be formed side by side in the threshold stop surface above the inner floor recess. This allows for 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 between the two paired support ribs above them in the threshold stop surface. This also contributes to material savings.

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

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

[0017] According to an advantageous embodiment of the invention, the respective recess can have, at least partially, straight inner walls, in particular walls that are angled to each other. Preferably, these walls can be designed with an orientation inclined towards the inside of the recess, which facilitates the demolding of the angled guide plate from the mold.

[0018] According to an advantageous embodiment of the invention, the threshold stop web can have a continuous material web extending from the top to the bottom of the threshold stop web without a recess in the area where the underside support webs are located. 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 material web, i.e., one located slightly further inside. In a paired arrangement, both the outer and the inner material web are designed as continuous material webs, i.e., as material webs 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 pressure area for the clamping clamp on the groove 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 exemplary embodiment

[0022] Advantageous embodiments of the present invention are explained in more detail with reference to examples in the drawings. For the sake of clarity, recurring features are indicated only once with a reference numeral. The drawings 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 as well as 2; Fig. 4 a top view of the top of the angle guide plate of Fig. 3 ; Fig. 5 a sectional view along the cutting surface AA of Fig. 4 Fig. 6 shows a sectional view along the cross-sectional surface BB of Fig. 4 ; Fig. 7 a side view of the angle guide plate according to Fig. 3 ; and Fig. 8 a top view of an end face area of ​​the angle guide plate according to Fig. 3 .

[0023] Fig. 1 Figure 1 shows an example of installing a rail 200 on a sleeper 100, for example a concrete or plastic sleeper, using an angle guide plate 300 according to the invention. The angle guide plate 300 is located between the rail foot 201 and a raised section 105 on the top of the sleeper 100. On the side of the raised section 105 facing the rail 200, a sleeper groove 101 is formed in the sleeper 100, into which the angle guide plate 300 engages and fixes it in position. The angle guide plate 300 also rests with its other side against the stop rib 202 of the rail foot 201. With the opposite side, the angle guide plate 300 is supported against the raised section 105 of the sleeper 100.

[0024] A spring-loaded clamping device 103 is fixed to the top of the angle guide plate 300 via a sleeper screw 102, such that the clamping device 103 rests on the rail foot 201 of the rail 200 on one side and on a groove 305 of the angle guide plate 300 on the other, as is particularly evident from Fig. 2 The angle guide plate 300 forms a stop 301 against the stop 202 of the rail foot 201. As shown from Fig. 2 As can be seen, the angle guide plate 300 is thus clamped between the raised section 105 of the sleeper 100 and the rail foot 201 of the rail 200 and fixed by means of the clamping clamp 103. The clamping clamp 103 rests against the top of the rail foot 201 and against the top 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 Figs. 1 and 2For the sake of clarity, a corresponding arrangement is shown only on one side of rail 200; a corresponding arrangement is located on both sides of rail 200.

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

[0028] The lateral threshold stop surface 304 has an outer recess 306 at both edges and several inner recesses 307 between them. In the lower area of ​​the threshold stop web 303, contact ribs 319, 320 are formed. On the opposite side, the groove 305 is formed into the base 309 of the angle guide plate 300 and serves to form a contact surface for the clamping 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 section 311 in the area of ​​the through-hole 302. The reference numeral 308 identifies the sprue.

[0030] In Fig. 4The contact areas 321 of the clamping clamp 103 are shown in the groove 305. The greatest contact pressure is applied there to the angle guide plate 300 via the clamping clamp 103.

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

[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. 7Force F1, F2 is applied to the sleeper 100 via the contact webs 319, 320 located on the underside of the angle guide plate 300 only in the opposite edge regions B1, B2, viewed in the direction of the rail 200. For this purpose, the force F1, F2 can be applied to the sleeper 100 in the respective edge regions B1, B2 of the angle guide plate 300 via contact webs 319, 320 arranged in pairs in the respective edge regions B1, B2 of the angle guide plate 300.

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

[0035] Above the internal floor recess 312, several recesses 307 are formed side by side in the sill stop surface 304. Likewise, a recess 306 is formed in the sill stop surface 304 between each of the two paired support ribs 319, 320.

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

[0037] The respective recess 306, 307 can, at least partially, have straight inner walls, in particular walls that run at an angle to each other, preferably with an orientation inclined towards the inside of the recess 306, 307.

[0038] The threshold stop web 303 forms a continuous material web 322, 323 from the top 318 to the bottom 317 of the threshold stop web 303 in the area of ​​the support webs 319, 320, without any recess in it. According to Fig. 7 A continuous outer material web 322 is located on the outside, and a further continuous inner material web 323 is located within the respective outer recess 306 and the adjacent inner recess 307. The force can be optimally transferred via the angle guide plate 300 to the threshold 100 via the material webs 322 and 323.

[0039] In this case, the inner material web 323 can, at least essentially, be assigned to the position of the contact area 321 for the clamping 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 threshold while simultaneously achieving significant material savings. The present invention of an angled guide plate thus represents a considerable advancement in the relevant field of technology. REFERENCE MARK LIST
