Description

[0001] The invention relates to an angle guide plate for fastening rails for rail vehicles to a sleeper using a tension spring that can be supported on the angle guide plate, comprising at least one support surface, in particular a support shoulder, formed on a top side of the angle guide plate for supporting the tension spring, a rail-side contact surface for a rail foot of the rail and a bottom side opposite the top side for supporting the angle guide plate on the sleeper.

[0002] The invention further relates to a fastening system for fastening rails for rail vehicles to a sleeper using the angle guide plate according to the invention and a sleeper for use in such a fastening system.

[0003] Publications US 9,103,073 B2, DE 101 57 676 A1 and US 2012 / 187206 A1 disclose angle guide plates and fastening systems for fastening rails for railway vehicles to a sleeper with reference to the subject matter of the present invention.

[0004] The installation of rails on a track bed is typically carried out using a spring element, usually referred to as a tension spring or clamp, and a suitable clamping element or hold-down device to tension the spring element. This clamping element or hold-down device is usually a screw that can be anchored in the sleeper, through which the spring element is tensioned against the subgrade so that it exerts the necessary holding forces via its section resting on the rail foot. The spring element is supported by an angled guide plate resting on the sleeper, which has a contact surface on the rail side for the rail foot, serving to guide the rail laterally. The purpose of the angled guide plate is to secure the rail against displacement in the track direction on the sleeper's bearing surface and to transfer the lateral wheel forces into the sleeper body.The angle guide plate is supported by an end face located on the side facing away from the rail against a support shoulder of the sleeper.

[0005] In the fastening system disclosed in WO 2011 / 032932 A1, the support shoulder of the sleeper and the end face of the angle guide plate cooperating with it run at an angle to the longitudinal direction of the rail, whereby a displacement of the angle guide plate relative to the sleeper in the longitudinal direction of the rail allows adaptation to different track gauges.

[0006] A disadvantage of this design, however, is that the angle guide plate and the rail are positioned in a recessed area of ​​the sleeper to allow the angle guide plate to be supported by the sleeper's shoulder. This weakens the sleeper's cross-section across the entire bearing area of ​​the rail and the angle guide plate, and brings the rail closer to the ballast bed, making tamping more difficult. To avoid these effects, the sleeper must be made higher in the rail bearing area, which also requires raising the sleeper's shoulders relative to the rail bearing. This increases the labor and material costs for manufacturing and / or processing the sleeper.

[0007] The present invention therefore aims to overcome the aforementioned disadvantages and to create, with reduced effort, an angle guide plate and an associated rail fastening system with associated sleeper, which allows the angle guide plate to be shifted relative to the substrate in the longitudinal direction of the rail to adapt to different track gauges, without requiring a material- and labor-intensive design of the substrate or the angle guide plate.

[0008] To solve this problem, according to a first aspect, the invention for an angle guide plate of the type mentioned at the outset essentially consists in the fact that a rib is formed on the underside which can be slidably received in a groove formed in the threshold, and that a guide surface extending at an acute angle to the rail-side contact surface is provided, so that by moving the rib in the groove an adjustment of the rail-side contact surface with a directional component extending perpendicular to the contact surface can be achieved.

[0009] The adjustment of the angled guide plate along an inclined guide surface is achieved by a rib formed on the underside of the angled guide plate. For guiding and supporting the rib, only a groove needs to be provided in the substrate, such as the sleeper, into which the rib engages. The remaining area of ​​the substrate requires no preparation, and in particular, the bearing surface of the rail and the angled guide plate can remain unchanged.

[0010] Preferably, the rib is formed in one piece with the angle guide plate.

[0011] The angle guide plate is composed of two separate parts. A first part may have the rib formed on its underside, and a second part may be supported by the first part in a direction perpendicular to the longitudinal direction of the rail.

[0012] Within the scope of the present invention, the term "transverse" with respect to a reference direction means that the corresponding direction extends perpendicular or obliquely to the reference direction. "Transverse to the longitudinal direction of the rail" thus means "perpendicular to the longitudinal direction of the rail" or "obliquely to the longitudinal direction of the rail".

[0013] As already mentioned, the tension spring is usually pre-tensioned by means of a tensioning screw anchored in the sleeper so that it exerts the required holding forces via its section(s) resting on the rail foot. The tensioning screw passes through the angle guide plate.

[0014] The two-part design of the angle guide plate is realized according to the invention such that a first part carries or is formed by the rib, which extends parallel to the rail-side contact surface, and a second part has the rail-side contact surface, wherein the first part is slidable along the guide surface on the second part. The adjustment of the rail-side contact surface in a perpendicular direction, i.e., perpendicular to the longitudinal direction of the rail, is thus effected by sliding the first part with its rib in the groove running parallel to the rail-side contact surface, wherein the first part with its guide surface slides on the inclined guide surface of the second part and adjusts the latter perpendicular to the direction of movement.

[0015] The available displacement of the first part and the acute angle of the guide surface to the contact surface determine the possible adjustment range of the second part perpendicular to the longitudinal direction of the rail. However, the displacement of the first part is limited, among other things, by the length of the groove formed in the sleeper. Furthermore, the acute angle to the contact surface cannot be arbitrarily steep, as this would require excessive space perpendicular to the longitudinal direction of the rail.To achieve the largest possible adjustment range of the second part perpendicular to the longitudinal direction of the rail while requiring minimal space, the first part and the second part each, according to the invention, have at least two guide surfaces extending at an acute angle to the rail-side contact surface. The first part is slidable along these guide surfaces on the second part, with the guide surfaces of each part arranged one behind the other in the direction of movement and offset from each other perpendicular to the direction of movement. The guide surfaces on the first part are preferably spaced further apart in the longitudinal direction of the rail by a recess than the preferably longer guide surfaces on the second part. This allows the guide surfaces to be designed with a steeper angle to the rail-side contact surface without increasing the space required perpendicular to the longitudinal direction of the rail.In particular, this achieves a small space requirement along the rail and allows for a limited displacement path in laterally closed grooves that do not extend over the entire width of the sleeper, so that a standard set of concrete sleepers already installed in the track can continue to be used or can be retrofitted with the angle guide plate according to the invention.

[0016] According to a preferred embodiment, the first and second parts have interoperating positive locking elements acting transversely to the direction of movement. These positive locking elements are preferably formed by at least one groove extending at an acute angle to the rail-side contact surface and a projection engaging in the groove. Such positive locking elements or the grooves facilitate the adjustment of the second part of the angle guide plate in both directions, i.e., away from and towards the rail, since the first and second parts are positively locked together and the first part, facing the rail, is also retracted in a continuous manner via the grooves / pins or projections when the rib is moved in the groove.

[0017] In order to allow the displacement of the second part of the angle guide plate transversely to the rail when a clamping screw is anchored in the sleeper, a slot extending from the top to the bottom is preferably also provided, the longitudinal axis of which runs perpendicular to the rail-side contact surface.

[0018] According to a preferred embodiment of the invention, the acute angle is 5-20°, preferably 10-13°. This allows lateral adjustment of the angled guide plate relative to the substrate such that a change in track width of up to 5 cm results. To achieve this even with a narrowly defined displacement path, the acute angle can, in a preferred embodiment, be correspondingly larger for guide surfaces arranged one behind the other in the displacement direction and offset from each other perpendicular to the displacement direction.

[0019] In order to allow the largest possible displacement range with a limited groove extension, it can be advantageous to provide that the angle guide plate has a greater width than the rib.

[0020] The rib can have a trapezoidal or round cross-section. A trapezoidal to rectangular cross-section of the rib or the correspondingly shaped groove has the advantage over a round cross-section that it can best replace the stop shoulder otherwise provided on the threshold.

[0021] To support the tension spring on the upper side of the angle guide plate and prevent it from slipping off the rail foot, the angle guide plate preferably has a support shoulder. The support shoulder is formed, in particular, in an end region of the angle guide plate facing away from the contact surface and can extend parallel to the contact surface.

[0022] The position of the tension spring on the angle guide plate can preferably be secured particularly well by the fact that the support shoulder is limited on its side facing the contact surface by a groove-shaped recess for the engagement of at least one rear support section of the tension spring.

[0023] Regarding the position of the rib on the underside of the angle guide plate, a preferred embodiment of the invention provides that the groove-shaped recess and the rib intersect, with the intersection point preferably located at the level of the elongated hole, i.e., approximately in the center of the angle guide plate. This, in conjunction with a tension spring having two rear support sections, allows for a configuration in which the two rear support sections of the tension spring, when the tension spring is mounted, engage in the groove-shaped recess on both sides of the center, with the bearing points of the support sections on the angle guide plate, viewed from above, being located on opposite sides of the rib. This has the effect of ideally securing the rib against lifting under load.At the same time, this results in a relative position between the rib and the channel-shaped depression, which enables a particularly narrow and therefore material-saving design of the angle guide plate.

[0024] Preferably, the tension spring may also be supported in a front area on the angle guide plate when assembled. For this purpose, the design is advantageously such that a bearing surface for supporting at least one front support section of the tension spring is formed on the upper side of the angle guide plate in an end area facing the contact surface.

[0025] In order to enable a positive locking interaction of the tension spring with the angle guide plate in various displacement positions and thus to secure the displacement position, it is preferably provided that the bearing surface has a plurality of parallel grooves running transversely, in particular perpendicularly to the contact surface, into which the at least one front support section of the tension spring engages to secure its position in one of several displacement positions of the angle guide plate.

[0026] According to a second aspect of the invention, a fastening system for fastening rails for railway vehicles to a sleeper is provided, comprising an angle guide plate that can be arranged on the sleeper according to the first aspect of the invention, and a sleeper which has at least one groove extending transversely to the longitudinal direction of the sleeper, into which the rib of the angle guide plate engages in a displaceable manner in the longitudinal direction of the groove when mounted, and further comprising a tension spring which has at least one support section that can be supported on the support surface of the angle guide plate and at least one rail retaining section, via which a holding force can be applied to the rail foot of the rail when the tension spring is mounted.

[0027] To provide the largest possible contact area between the rib and the groove, it is preferably intended that the rib and the groove have corresponding cross-sections. If the rib has a trapezoidal cross-section, the groove advantageously also has a correspondingly dimensioned trapezoidal cross-section so that the rib can be slidably mounted in the groove with minimal play.

[0028] As already explained in connection with the first aspect of the invention, the inventive design of the angle guide plate with a rib formed on its underside requires only the formation of a groove on the sleeper, but no further machining of the sleeper, so that, in particular, the bearing level of the rail and the angle guide plate can remain the same. A stepless design here means that, besides the angle guide plate, no stop shoulders projecting beyond a rail bearing area are formed or formed on the sleeper for lateral support or guidance. In other words, the surface areas of the sleeper adjacent to the groove lie in the same plane on both sides of the groove, i.e., on the side facing the rail bearing area and on the side facing away from the rail bearing area.

[0029] The groove can be subsequently produced, for example, by milling, particularly if the sleeper was manufactured as a precast concrete element in one piece. Alternatively, the groove can be imprinted during sleeper production by means of a mold inserted into the formwork for shaping the precast concrete element. This allows for extremely simple production of the sleeper with a standard, block-like shape without stepped or recessed surface areas. The design according to the invention is also suitable for plastic-based sleepers.

[0030] In this context, a preferred design provides for the groove to extend across the entire width of the threshold. This further simplifies the manufacturing process and also allows for the largest possible adjustment range of the angle guide plate relative to the threshold.

[0031] As is known in itself, the fastening system preferably further comprises a tensioning screw which can be anchored in a bore of the threshold by passing through the elongated hole of the angle guide plate in order to tension the tension spring.

[0032] The tension spring can have at least one rear support section that can be supported against the support shoulder of the angle guide plate.

[0033] The tension spring can further have two rear support sections and the angle guide plate can have corresponding support surfaces on which the support sections rest when the tension spring is mounted, the support surfaces being arranged on opposite sides of the rib when viewed from above.

[0034] Furthermore, the tension spring can have at least one front support section which, in the assembled state, can be supported on the bearing surface of the angle guide plate located in the end area facing the contact surface.

[0035] Preferably, the tension spring is essentially "ω"-shaped, with its free ends forming the rail support section and preferably its central section projecting beyond the rail foot by a distance from the front support sections. The central section advantageously acts as an overload protection mechanism, which becomes effective when the rail foot rises due to excessive load by a distance corresponding to the aforementioned distance, thus preventing further rising of the rail foot and, consequently, further deformation of the rail support sections.

[0036] Preferably, an alternative design of the tension spring can be used, which is similar to an "e" shape, with the difference that the end section of the "e" shape has an additional inward bend.

[0037] Such a tension spring preferably comprises a U-shaped main section, which has a U-bend, a first leg arranged on one side of the U-bend and a second leg arranged on the other side of the U-bend, wherein a hook-shaped inwardly bent support or holding section, which can be supported on a hold-down device, is formed on the first leg and an end section bent towards or away from the support or holding section is formed on the second leg, wherein the U-bend forms a torsion section, so that a holding force can be applied to the track element via the bent end section.

[0038] The bent end section forms the portion of the tension spring through which the holding force is applied to the rail foot. The hook-shaped retaining section extending from the first leg of the U-shape serves to be held under tension by a tensioning screw when a torsional force is exerted from the bent end section on the torsional section formed by the U-shaped arc of the tension spring. The hook-shaped retaining section is bent inwards, meaning that the hook is bent between the two legs of the U-shape. Preferably, the hook-shaped support or retaining section on the side of the first leg forms the end of the tension spring, i.e., the free end of the section bent into a hook lies between the two legs of the U-shape. The retaining section can be supported, at least partially, on a base such as the angle guide plate according to the invention and thus corresponds to a support section.

[0039] Preferably, the bent end section runs at an angle of 80-100°, preferably approximately 90°, to the second leg.

[0040] Preferably, a hook arc of the support or holding section has a substantially 180° bend, so that a free end area of ​​the support or holding section runs substantially parallel to the first leg, at least in sections.

[0041] Preferably, an imaginary extension of the bent end section overlaps the hook arc in a top view.

[0042] Preferably, the first leg and the support or holding section lie in the same plane when unloaded.

[0043] Preferably, the second leg, when unloaded, is inclined at an acute angle relative to the common plane of the support or holding section and the first leg, and preferably lies in an inclined plane spanned by the second leg and a straight line perpendicular to the axis of the first leg, forming a tangent to the U-shaped arc.

[0044] Preferably, the second leg and the bent end section lie in the inclined plane in the unloaded state, or the bent end section is bent upwards relative to the inclined plane.

[0045] Furthermore, a threshold for use in a fastening system according to the invention is described, comprising a top surface with support areas arranged at a distance of one track width for each rail, wherein on both sides of each support area a groove is formed running at an acute angle to the longitudinal direction of the rail, in which the rib formed on the underside of the angle guide plate can be slidably received in the longitudinal direction of the groove.

[0046] As already explained in connection with the second aspect of the invention, the groove can extend across the entire width of the threshold. Alternatively, the groove can also be designed such that it terminates at both ends at a distance from the respective side surface of the threshold.

[0047] Advantageously, the sleeper, with the exception of the groove and any holes for anchoring tensioning screws, requires no further machining and is designed in such a way that the upper surface of the sleeper is stepless, except for the angled grooves. This largely eliminates the need for additional material that would be required for support shoulders or steps of the sleeper that are raised relative to the rail bearing area. This has a particularly positive effect on the CO₂ balance, especially in the case of concrete sleepers.

[0048] In this context, stepless design means that no stop shoulders projecting beyond the bearing area of ​​a rail are formed or formed on the threshold next to the angle guide plate for lateral support or guidance.

[0049] The invention is explained in more detail below with reference to exemplary embodiments schematically illustrated in the drawing. In this drawing, Fig. 1 und 2 two perspective views of a rail attached to a threshold by means of a fastening system not according to the invention, Fig. 3 a perspective top view of an angle guide plate not according to the invention, Fig. 4 a perspective bottom view of the angle guide plate of Fig. 3, Fig. 5 a top view and Fig. 6 a side view of the angle guide plate of Fig. 3 , Fig. 7 a threshold according to the invention, Fig. 8 an inventive embodiment of a fastening system with an inventive, two-part angle guide plate, Fig. 9 a perspective view of the angle guide plate according to Fig. 8, Fig. 10 a front view of the angle guide plate according to Fig. 8, Fig. 11 a bottom view of the angle guide plate according to Fig. 8 in an expanded representation, Fig. 12 a perspective view of a tension spring, Fig. 13 a top view of the tension spring according to Fig. 12, Fig. 14 a view according to arrow I of the Fig. 13 und Fig. 15 a view according to arrow II of the Fig. 13 .

[0050] In Fig. 1 und 2 A sleeper 1 is shown, on which a rail 2 rests. The rail foot 3 of the rail 2 is secured on both sides of the rail 1 by an angle guide plate 4, each of which has a rail-side contact surface 5 for the rail foot 3. To hold the rail foot 3 in place, a tension spring 6 is provided on each side, which is held under tension by a tension screw 7. The tension spring 6 is essentially "ω"-shaped and has two rear support sections 8, which bear against a support shoulder 9 of the angle guide plate 4 and engage in a groove-shaped recess 10. The free ends of the tension spring 6 each form a rail-holding section 11, which exerts a holding force on the rail foot 3 of the rail 2. The tension spring 6 also has two front support sections 17 in the area of ​​the tension screw 7 ( Fig. 2 ) on, which rests on a support surface 12 ( Fig. 3 ) the angle guide plate 4, which has a plurality of parallel grooves 13 running perpendicular to the contact surface 5 ( Fig. 3 ) into which the front support sections 17 of the tension spring 6 engage. The tension spring 6 further has a central section 14, which extends from the front support sections 17 of the tension spring 6 and projects beyond the rail foot 3 by a distance in order to form an overload protection.

[0051] A rib 15 is formed on the underside 19 of the angle guide plate 4, which runs obliquely to the longitudinal direction of the rail and engages slidably in a groove 16 of the sleeper 1. This allows the angle guide plate 4 to move along an inclined guide surface 41 ( Fig. 4 und 6 ) relative to the threshold 1 and relative to the rail 2, which allows for adaptation to different track gauges or rail positions.

[0052] In the Fig. 3 bis 6 The angle guide plate 4 is shown separately, and the elongated hole 18, whose longitudinal axis runs parallel to the rib 15, is now also visible. The elongated hole 18 is formed between the support shoulder 9 and the contact surface 5. As shown by the dashed lines in the top view according to Fig. 5 As shown, the channel-shaped recess 10 and the rib 15 intersect each other, with the intersection point 24 being located in the plan view at the level of the elongated hole 18, and in particular approximately in the middle of the angle guide plate 4 with respect to its length. Here, the centerline of the channel-shaped recess 10 is designated 21, the centerline of the rib 15 22, and the centerline of the angle guide plate 4 23. In this plan view, the acute angle between the guide surface 41 (not visible) and the rail-side contact surface 5 is enclosed by the centerlines 21 and 22.

[0053] The two support surfaces on which the rear support sections 8 of the tension spring 6 rest in the central position of the tension spring 6 are designated 25 and it can be seen that the support surfaces 25 are arranged on opposite sides of the rib 15 (i.e. the center line 22) when viewed from above.

[0054] In Fig. 7 The threshold 1 is shown separately and it is evident that the threshold 1, with the exception of the grooves 16 and the bores 20 for receiving the clamping screws 6, has no machining, offset areas, depressions and / or gradations of the surface.

[0055] Fig. 8-11 Figure 1 shows an embodiment of a fastening system according to the invention, in which the angle guide plate 4 is designed in two parts and an alternative embodiment of the tension spring 34 is used. The angle guide plate 4 consists, as shown in the figures, of two parts. Fig. 9 und 11 As can be seen, the rail consists of a first part 26 facing away from the rail 2 and a second part 27 facing the rail 2. The first part 26 carries a rib 15 which engages in the groove 16 when installed, the rib 15 preferably having a trapezoidal cross-section and at least one guide surface 28 being provided. The first and second parts 26, 27 are guided along guide surfaces 28, 29 which are inclined to the longitudinal direction of the rail. Fig. 11 ) are movable relative to each other to allow adjustment to the respective track gauge. The second part 27 further comprises a plate-shaped support element 30 on which the tension spring 34 rests and which overlaps the upper surface of the first element 26. As in Fig. 11 As can be seen, the plate-shaped support element 30 has at least one inclined guide groove 31 on its underside, into which guide pins or projections (not shown) formed on the top side of the first element 26 engage in order to hold the two parts 26,27 together, especially in the unloaded state.

[0056] Furthermore, it is evident that the second part 27, in particular the plate-shaped support element 30, has a through-hole 18 which, in the assembled state of an exemplary tension spring 34, is penetrated by the screw 7. The through-hole 18 is designed as an elongated hole perpendicular to the longitudinal direction of the rail. For lateral guidance of the tension spring 34, the second part 27, in particular the plate-shaped support element 30, has two walls 31 which extend in the insertion direction 32 of the tension spring 34. The projection 33, which is arranged between the first leg 36 and the free end 40 of the support or retaining section 38 of the tension spring 34, also serves to guide the tension spring 34 (see Fig. 12-15 ).

[0057] The tension spring 34 can be positioned between the in Fig. 8 The tension spring 34 can be moved between the illustrated final assembly position and a pre-assembly position (not shown) in which it does not extend beyond the rail foot. The design is such that the screw 7 does not need to be loosened to move the tension spring 34 from the pre-assembly position to the final assembly position. This movement can be accomplished, for example, using a lever-like tool.

[0058] The fastening system according to the Fig. 8-11 The tension spring 34 used is described below based on the Fig. 12-15 The tension spring 34 is described in more detail below. It comprises a U-shaped main section, which has a U-bend 35, a first leg 36 arranged on one side of the U-bend 35, and a second leg 37 arranged on the other side of the U-bend 35. The first leg 36 has a hook-shaped, inwardly bent support or retaining section 38, which can be supported on a hold-down clamp or an angled guide plate. The second leg 37 has an end section 39 that is bent towards or away from the support or retaining section 38. The retaining section 38 includes a free end 40.

[0059] In Fig. 14 It can be seen that the bent end section 39 is slightly inclined upwards, so that there is an acute angle α between the bent end section 39 and the plane of the support or holding section 38 and the first leg 36.

[0060] In Fig. 15It can be seen that the second leg 37 forms an acute angle β with the plane of the support or holding section 38 and the first leg 36.
