Description

[0001] Angle guide plate and fastening system for fastening rails for rail vehicles

[0002] 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 an upper side of the angle guide plate for supporting the tension spring, a rail-side contact surface for a rail foot of the rail and an underside opposite the upper side for supporting the angle guide plate on the sleeper.

[0003] 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 to a sleeper for use in such a fastening system.

[0004] The installation of rails on a track body is usually carried out using a spring element, usually referred to as a tension spring or tension clamp, and a suitable tensioning element or hold-down device to brace the spring element. This tensioning element or hold-down device is usually a screw that can be anchored in the sleeper and by means of which the spring element is braced against the substructure so that it exerts the necessary holding forces via the section resting on the rail foot. The spring element is supported on an angled guide plate resting on the sleeper, which has a contact surface on the rail side for a rail foot of the rail, which serves to guide the rail laterally. The purpose of the angled guide plate is to secure the rail on the support surface of the sleeper against displacement in the transverse direction of the track and to transfer the lateral wheel forces to the sleeper body.The angle guide plate is supported by a front face on the side facing away from the rail on 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 interacting with it run obliquely 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 angled guide plate and the rail are arranged in a recessed area of ​​the sleeper to allow support of the angled guide plate on the support shoulder of the sleeper. The cross-section of the sleeper is weakened across the entire support area of ​​the rail and the angled guide plates, and the rail comes to lie closer to the ballast bed, which makes tamping more difficult. To avoid these effects, the sleeper must be made higher in the support area of ​​the rails, and the support shoulders of the sleeper must also be raised relative to the rail support. This increases the labor and material required for manufacturing and / or machining the sleeper.

[0007] The present invention therefore aims to overcome the above-mentioned disadvantages and to create, with reduced effort, an angled guide plate and an associated rail fastening system with associated sleeper, which allows a displacement of the angled guide plate relative to the substructure in the longitudinal direction of the rail for adaptation to different track gauges, without the need for a material- and labor-intensive design of the substructure or the angled guide plate.

[0008] To achieve this object, the invention according to a first aspect in an angle guide plate of the type mentioned at the outset essentially consists in that a rib is formed on the underside which can be displaceably received in a groove formed in the sleeper, and in that a guide surface is provided which runs at an acute angle to the rail-side contact surface, so that by displacing the rib in the groove an adjustment of the rail-side contact surface with a directional component running perpendicular to the contact surface can be realized.

[0009] The adjustment of the angle guide plate along an inclined guide surface is thus achieved by a rib formed on the underside of the angle guide plate. To guide and support the rib, only a groove is required in the substructure, such as the sleeper, into which the rib engages. The remaining area of ​​the substructure requires no machining, and in particular, the support level of the rail and the angle guide plate can remain the same.

[0010] Preferably, the rib is formed integrally with the angle guide plate.

[0011] The angle guide plate can be formed as a single piece or composed of two separate parts. A first part can have a rib formed on its underside, and a second part can be supported on the first part in a direction transverse to the longitudinal direction of the rail.

[0012] In the context 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] The one-piece design can preferably be realized in such a way that the guide surface is formed on the rib, which, in a plan view, extends at an acute angle to the rail-side contact surface. In other words, a rib is formed on the underside of the angled guide plate, which extends at an acute angle to the rail-side contact surface, which rib can be slidably received in the groove formed in the sleeper and which supports the guide surface.

[0014] As already mentioned, the tension spring is usually pre-tensioned by means of a tensioning screw which can be 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. In order to allow a displacement of the angle guide plate relative to the sleeper in the longitudinal direction of the rail in the case of a one-piece design of the angle guide plate, a preferred embodiment of the invention provides that the angle guide plate has an elongated hole extending from the top side to the bottom, the longitudinal axis of which runs parallel to the rib, the elongated hole preferably being formed between the support shoulder and the contact surface. The adjustability of the angle guide plate relative to the sleeper is determined by the length of the elongated hole.

[0015] A two-part design of the angle guide plate can preferably be realized in such a way that a first part carries the rib 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 displaceable along the guide surface on the second part. The adjustment of the rail-side contact surface in the vertical direction, i.e. perpendicular to the longitudinal direction of the rail, thus takes place by displacing the first part with its rib in the groove running parallel to the rail-side contact surface, wherein the first part slides with its guide surface on the inclined guide surface of the second part and adjusts the latter perpendicular to the direction of displacement.

[0016] The available displacement of the first part and the acute angle of the guide surface to the contact surface determine the possible adjustment 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 chosen as steep as desired, as this would require excessive space transverse to the longitudinal direction of the rail.In order to achieve the greatest possible adjustment path of the second part perpendicular to the longitudinal direction of the rail with little space required, the first part and the second part preferably each have at least two guide surfaces running at an acute angle to the rail-side contact surface, along which guide surfaces the first part can be moved on the second part, wherein the guide surfaces of the respective part are arranged one behind the other in the direction of displacement and offset from one another perpendicular to the direction of displacement. The guide surfaces on the first part are preferably spaced further apart from one another 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 a limited displacement path in laterally closed grooves that do not extend over the entire sleeper width is sufficient, so that a standard concrete sleeper set already installed in the track can continue to be used or can be retrofitted with the angle guide plate according to the invention.

[0017] According to a further preferred embodiment, it is provided that the first and the second part have form-locking elements which interact with one another and act transversely to the direction of displacement, wherein the form-locking elements are preferably formed by at least one groove running at an acute angle to the rail-side contact surface and a projection engaging in the groove. Such form-locking elements or the grooves facilitate the adjustment of the second part of the angle guide plate in both directions, i.e. away from the rail and towards the rail, since the first and the second part are held together in a form-locking manner and the first part facing the rail is also retracted again in a continuous manner via the grooves / pins or projections when the rib is moved in the groove.

[0018] In order to allow the displacement of the second part of the angle guide plate transversely to the rail when a tensioning screw is anchored in the sleeper, an elongated hole extending from the top to the bottom is preferably provided, the longitudinal axis of which extends perpendicular to the rail-side contact surface.

[0019] According to a preferred development of the invention, the acute angle is 5-20°, preferably 10-13°. This allows lateral adjustment of the angled guide plate relative to the ground such that the track width can be changed by up to 5 cm. To achieve this even with a narrowly defined displacement path, the acute angle can, in a preferred development, be provided correspondingly larger for guide surfaces arranged one behind the other in the displacement direction and offset perpendicular to the displacement direction.

[0020] In order to allow the greatest possible displacement path with a limited extension of the groove, it can advantageously be provided that the angle guide plate has a greater width than the rib.

[0021] The rib can have a trapezoidal or round cross-section. A trapezoidal to rectangular cross-section of the rib or of the correspondingly shaped groove has the advantage over a round cross-section that it is the best way to replace the stop shoulder otherwise provided on the sleeper. To support the tension spring on the upper side of the angled guide plate so that the tension spring is prevented from slipping off the rail foot, the angled guide plate preferably has a support shoulder. The support shoulder is formed in particular in an end region of the angled 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 in that the support shoulder is delimited 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] With regard to the position of the rib on the underside of the angle guide plate, a preferred development of the invention provides that the groove-shaped depression and the rib cross one another, with the crossing point preferably being located at the level of the elongated hole, i.e. approximately in the middle of the angle guide plate. In conjunction with a tension spring which has two rear support sections, this enables a design in which the two rear support sections of the tension spring, when the tension spring is in the assembled state, engage in the groove-shaped depression on both sides of the middle, with the contact points of the support sections on the angle guide plate being located on opposite sides of the rib when viewed from above. This has the effect that the rib is ideally secured against lifting off under load.At the same time, there is a relative position between the rib and the groove-shaped recess, which results in a particularly narrow and thus material-saving design of the angle guide plate.

[0024] Preferably, it can be provided that the tension spring, in the assembled state, is also supported in a front region on the angled guide plate. For this purpose, the design is advantageously such that a support surface for supporting at least one front support section of the tension spring is formed in an end region facing the contact surface on the upper side of the angled guide plate.

[0025] In order to enable a positive interaction of the tension spring with the angle guide plate in different displacement positions and thus to secure the displacement position, it is preferably provided that the support surface has a plurality of parallel grooves running transversely, in particular perpendicular to the contact surface, into which the at least one front support section of the tension spring engages to secure the 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 rail vehicles to a sleeper is provided, comprising an angle guide plate according to the first aspect of the invention which can be arranged on the sleeper, and a sleeper which has at least one groove running transversely to the longitudinal direction of the sleeper, into which groove the rib of the angle guide plate engages displaceably in the longitudinal direction of the groove in the assembled state, and further comprising a tension spring which has at least one support section which can be supported on the support surface of the angle guide plate and at least one rail holding section via which a hold-down force can be applied to the rail foot of the rail in the assembled state of the tension spring.

[0027] In order to provide the largest possible contact area between the rib and the groove, it is preferably provided 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 received in the groove with as little play as possible.

[0028] As already explained in connection with the first aspect of the invention, the inventive design of the angled guide plate with a rib formed on the underside only requires the formation of a groove on the sleeper, but otherwise no further processing of the sleeper, so that in particular the support level of the rail and the angled guide plate can remain the same. A stepless design is understood here to mean that on the sleeper next to the angled guide plate no stop shoulders projecting beyond a support area of ​​a rail 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 support area for the rail and on the side facing away from the support area for the rail. The groove can in this case e.g.be subsequently produced by milling, particularly if the sleeper was manufactured as a single-piece precast concrete component. The groove can also be embossed during sleeper manufacture using a mold inserted into the formwork for shaping the precast concrete component. This allows for extremely simple production of the sleeper with a block-like standard shape without stepped or recessed surface areas. The design according to the invention is also suitable for plastic-based sleepers.

[0029] In this context, a preferred design provides for the groove to extend across the entire width of the sleeper. This further simplifies the manufacturing process and also allows the largest possible adjustment range of the angle guide plate relative to the sleeper.

[0030] As is known per se, the fastening system preferably further comprises a tensioning screw which can be anchored in a bore of the threshold through the oblong hole of the angle guide plate in order to tension the tension spring.

[0031] The tension spring can have at least one rear support section which can be supported against the support shoulder of the angle guide plate.

[0032] The tension spring can further comprise two rear support sections, and the angled guide plate can comprise corresponding support surfaces on which the support sections rest when the tension spring is in its assembled state. The support surfaces are arranged on opposite sides of the rib when viewed in plan view. Furthermore, the tension spring can comprise at least one front support section, which, when assembled, can be supported on the support surface of the angled guide plate arranged in the end region facing the contact surface.

[0033] Preferably, the tension spring is substantially "©"-shaped, the free ends of which each form the rail holding section and preferably the middle section of which projects beyond the rail foot at a distance from the front support sections. The middle section advantageously forms an overload protection which comes into effect when the rail foot rises by an amount corresponding to the said distance due to excessive loading and which prevents further rising of the rail foot and thus further deformation of the rail holding sections.

[0034] In a design with a two-part angle guide plate, an alternative design of the tension spring can preferably be used, which is similar to an "e" shape, with the difference that the end section of the "e" shape has an additional, inwardly directed bend.

[0035] 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 on the first leg there is formed a hook-shaped support or holding section which is bent inwards and can be supported on a hold-down device, and on the second leg there is formed an end section which is bent towards or away from the support or holding section, wherein the U-bend forms a torsion section so that a hold-down force can be applied to the track body element via the bent end section.

[0036] The bent end section forms the area of ​​the tension spring via which the hold-down force is applied to the rail foot. The hook-shaped holding section extending from the first leg of the U-shape is used to be held under tension by a tensioning screw when a torsional force is exerted by the bent end section on the torsional section formed by the U-bend of the tension spring. The hook-shaped holding section is bent inwards, which can be understood to mean that the hook is bent between the two legs of the U-shape. Preferably, the hook-shaped support or holding section on the first leg forms the end of the tension spring, i.e. the free end of the area bent into a hook lies between the two legs of the U-shape. The holding section can be at least partially on a base such as e.g.the angle guide plate according to the invention and thus corresponds to a support section.

[0037] Preferably, the bent end section extends at an angle of 80-100°, preferably approximately 90°, to the second leg.

[0038] Preferably, a hook bend of the support or holding section has a substantially 180° bend, so that a free end region of the support or holding section runs substantially parallel to the first leg, at least in sections. Preferably, an imaginary extension of the bent end section overlaps the hook bend in a plan view.

[0039] Preferably, the first leg and the support or holding section lie in the same plane in the unloaded state.

[0040] Preferably, in the unloaded state, the second leg extends 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 which is spanned by the second leg and a straight line which is normal to the axis of the first leg and forms a tangent to the U-bend.

[0041] 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.

[0042] According to a further aspect of the invention, a sleeper is provided for use in a fastening system according to the invention, comprising an upper side with support areas arranged at a distance of one track width for one rail each, wherein on both sides of each support area there is formed a groove which runs at an acute angle to the longitudinal direction of the rail and in which the rib formed on the underside of the angle guide plate can be received so as to be displaceable in the longitudinal direction of the groove. The groove which runs at an acute angle to the longitudinal direction of the rail can also be defined as a groove which runs at an acute angle to the longitudinal direction of the sleeper, since the longitudinal direction of the rail extends perpendicular to the longitudinal direction of the sleeper. As already explained in connection with the second aspect of the invention, the groove can extend over the entire width of the sleeper.Alternatively, the groove can also be designed so that it ends at both ends at a distance from the respective side surface of the sleeper.

[0043] Advantageously, the sleeper requires no further processing, except for the groove and any holes for anchoring tensioning bolts. It is designed in such a way that the sleeper is seamlessly stepped on its upper side, except for the angled grooves. This largely eliminates the need for additional material for supporting shoulders or steps on the sleeper that are raised relative to the rail support area. This has a positive effect on the CO2 balance, particularly with concrete sleepers.

[0044] A stepless design is understood here to mean that on the sleeper, next to the angle guide plate, there are no stop shoulders formed or formed on the sleeper that project beyond a support area of ​​a rail for lateral support or guidance.

[0045] The invention is explained in more detail below with reference to exemplary embodiments shown schematically in the drawing. In this drawing: Fig. 1 and 2 show two perspective views of a rail fastened to a sleeper by means of a fastening system according to the invention, Fig. 3 is a perspective top view of an angle guide plate according to the invention, Fig. 4 is a perspective bottom view of the angle guide plate from Fig. 3, Fig. 5 is a top view and Fig. 6 is a side view of the angle guide plate from Fig. 3, Fig. 7 is a sleeper according to the invention, Fig. 8 is a modified embodiment of a fastening system with a two-part angle guide plate, Fig. 9 is a perspective view of the angle guide plate according to Fig. 8, Fig. 10 is a front view of the angle guide plate according to Fig. 8, Fig. 11 is an exploded bottom view of the angle guide plate according to Fig. 8,Fig. 12 is a perspective view of a tension spring, Fig. 13 is a plan view of the tension spring according to Fig. 12, Fig. 14 is a view according to arrow I of Fig. 13 and Fig. 15 is a view according to arrow II of Fig. 13.

[0046] 1 and 2 show a sleeper 1 on which a rail 2 rests. The rail foot 3 of the rail 2 is secured in position on both sides of the rail 1 by an angled guide plate 4, each of which has a rail-side contact surface 5 for the rail foot 3. To hold down the rail foot 3, 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 "©"-shaped and has two rear support sections 8, which are supported on a support shoulder 9 of the angled 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 hold-down force on the rail foot 3 of the rail 2. In the area of ​​the tensioning screw 7, the tension spring 6 further comprises two front support sections 17 (Fig. 2) which rest on a support surface 12 (Fig.3) of the angled guide plate 4, which has a plurality of parallel grooves 13 (Fig. 3) running transversely to the contact surface 5, 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 at a distance, thereby forming an overload protection device.

[0047] On the underside 19 of the angled guide plate 4, a rib 15 is formed, which runs obliquely to the longitudinal direction of the rail and slidably engages in a groove 16 of the sleeper 1. This allows the angled guide plate 4 to be displaced along an inclined guide surface 41 (Figs. 4 and 6) relative to the sleeper 1 and relative to the rail 2, which allows adaptation to different track gauges or rail positions.

[0048] 3 to 6, the angle guide plate 4 is shown separately and the elongated hole 18 can also be seen, the longitudinal axis of which runs parallel to the rib 15. The elongated hole 18 is formed between the support shoulder 9 and the contact surface 5. As shown by dashed lines in the plan view according to Fig. 5, the groove-shaped depression 10 and the rib 15 cross one another, the crossing point 24 in the plan view being arranged at the level of the elongated hole 18, in particular with regard to the length of the angle guide plate 4 approximately in the middle of the angle guide plate 4. The center line of the groove-shaped depression 10 is designated 21, the center line of the rib 15 is designated 22 and the center line of the angle guide plate 4 is designated 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 center lines 21, 22.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 (ie the center line 22) as seen in plan view.

[0049] In Fig. 7, the sleeper 1 is shown separately and it can be seen that the sleeper 1, with the exception of the grooves 16 and the bores 20 for receiving the clamping screws 6, has no machining, stepped areas, depressions and / or gradations of the surface.

[0050] Fig. 8-11 show a modified embodiment of a fastening system in which the angled guide plate 4 is constructed in two parts and an alternative design of the tension spring 34 is used. The angled guide plate 4 consists, as can be seen in Figs. 9 and 11, 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, when installed, engages in the groove 16. The rib 15 preferably has a trapezoidal cross-section and at least one guide surface 28 is provided. The first and second parts 26, 27 are displaceable relative to one another along guide surfaces 28, 29 (Fig. 11) which are inclined to the longitudinal direction of the rail, in order to thereby enable adaptation 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 engages over the upper surface of the first element 26. As can be seen in Fig. 11, 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 upper side of the first element 26 engage in order to hold the two parts 26, 27 together, particularly in the unloaded state.

[0051] Furthermore, it can be seen that the second part 27, in particular the plate-shaped support element 30, has a through-hole 18 through which the screw 7 passes when an exemplary tension spring 34 is mounted. The through-hole 18 is designed as an elongated hole perpendicular to the longitudinal direction of the rail. For the lateral guidance of the tension spring 34, the second part 27, in particular the plate-shaped support element 30, has two walls 31 that run in the insertion direction 32 of the tension spring 34. The elevation 33, which is arranged between the first leg 36 and the free end 40 of the support or holding section 38 of the tension spring 34 (see Fig. 12-15), also serves to guide the tension spring 34.

[0052] The tension spring 34 can be moved between the final assembly position shown in Fig. 8 and a pre-assembly position (not shown), in which the tension spring 34 does not overlap 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. The movement can be achieved, for example, using a lever-like tool.

[0053] The tension spring 34 used in the fastening system according to Figs. 8-11 is described in more detail below with reference to Figs. 12-15. The tension spring 34 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. On the first leg 36 there is formed a hook-shaped, inwardly bent support or holding section 38 which can be supported on a hold-down device or an angle guide plate, and on the second leg 37 there is formed an end section 39 which is bent towards or away from the support or holding section 38. The holding section 38 comprises a free end 40.

[0054] In Fig. 14 it can be seen that the bent end section 39 is slightly inclined upwards, so that an acute angle a is present between the bent end section 39 and the plane of the support or holding section 38 and the first leg 36.

[0055] In Fig . 15 it can be seen that the second leg 37 forms an acute angle ß with the plane of the support or .

[0056] holding section 38 and the first leg 36.
