Description

Technical Field

[0001] The invention relates to an angled guide plate for fastening a rail for a rail vehicle to a sleeper using a clamping spring which can be supported on the angled guide plate, comprising: at least one supporting surface, in particular a supporting shoulder, which is formed on the upper side of the angled guide plate and serves to support the clamping spring; a rail-side contact surface for a rail foot (Schienenfuβ, sometimes referred to as rail bottom) of the rail; and a lower side, which is opposite the upper side and serves to support the angled guide plate on the sleeper.

[0002] The invention further relates to a fastening system for fastening a rail for a rail vehicle to a sleeper using the angled guide plate according to the invention and to a sleeper for use in such a fastening system. Background Art

[0003] Rail system The rail mounting is usually carried out using a spring element (usually called a clamping spring or clamp) and a suitable clamping element or a clamping device for clamping the spring element. The clamping element or the clamping device is usually a screw that can be anchored in the sleeper, by which the spring element is clamped against a base in such a way that it exerts the required holding force via its 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 for the rail foot of the rail on the rail side, which serves to guide the rail in the lateral direction. The angled guide plate has the following purpose: to fix the rail on the support surface of the sleeper to prevent movement in the transverse direction of the rail and to transmit the lateral forces of the wheel to the sleeper body. The angled guide plate is supported on the support shoulder of the sleeper with its end face arranged on the side facing away from the rail.

[0004] In the fastening system disclosed in WO 2011 / 032932 A1, the supporting shoulder of the sleeper and the end face of the angular guide plate cooperating therewith extend obliquely to the longitudinal direction of the track, whereby the movement of the angular guide plate relative to the sleeper in the longitudinal direction of the track allows adaptation to different track gauges (Spurweite, sometimes called wheelbases).

[0005] However, a disadvantage of this embodiment is that the angled guide plate and the rail are arranged in the recessed area of ​​the sleeper in order to be able to support the angled guide plate on the support shoulder of the sleeper. The cross section of the sleeper is weakened in the entire support area of ​​the rail and the angled guide plate, and the rail is closer to the ballast, which makes the compaction process more difficult. In order to avoid these effects, the sleeper must be made higher in the support area of ​​the rail, wherein the support shoulder of the sleeper must also be raised relative to the rail support. This increases the work and material expenditure for manufacturing and / or processing the sleeper. Summary of the invention

[0006] The present invention therefore aims to overcome the above-mentioned disadvantages and to create an angle guide plate and a corresponding rail fastening system with corresponding sleepers at reduced cost, which allows the angle guide plate to be moved relative to the base in the longitudinal direction of the rail to adapt to different track gauges, without requiring a material and work-intensive design of the base or the angle guide plate.

[0007] In order to achieve this task, the present invention, according to a first aspect, is basically characterized in that for an angle guide plate of the type mentioned at the beginning, a rib-shaped portion is constructed on the lower side, which can be movably accommodated in a groove constructed in the sleeper, and a guide surface extending at an acute angle to the contact surface on the rail side is provided, so that the contact surface on the rail side can be adjusted with a directional component extending perpendicular to the contact surface by moving the rib-shaped portion in the groove.

[0008] Thus, the angled guide plate is adjusted along the inclined guide surface by means of the ribs, which are formed on the underside of the angled guide plate. For guiding and supporting the ribs, only grooves are provided in the base, for example the sleepers, into which the ribs engage. The remaining areas of the base do not need to be machined, wherein in particular the support levels of the rail and the angled guide plate can remain the same.

[0009] Preferably, the ribs are formed in one piece with the angled guide plate.

[0010] The angled guide plate can be constructed as a single piece or can be formed by combining two independent parts. Here, the first part can have a rib-shaped portion configured at its underside, and the second part can be supported at the first part in a direction extending transversely to the longitudinal direction of the track.

[0011] In the context of the present invention, the term "transversely" with respect to a reference direction means that the respective direction extends perpendicularly or obliquely to the reference direction. Thus, "transversely to the rail longitudinal direction" means "perpendicularly to the rail longitudinal direction" or "obliquely to the rail longitudinal direction".

[0012] The one-piece construction can preferably be realized in such a way that the guide surface is formed on a rib which, in a top 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, can be movably received in a groove formed in the sleeper and carries the guide surface.

[0013] As already mentioned, the clamping spring is usually pre-tensioned by means of a clamping screw which can be anchored in the rail sleeper in such a way that the clamping spring exerts the required holding force via its section which rests on the rail foot. The clamping screw passes through the angled guide plate. In order to allow a displacement of the angled guide plate relative to the rail sleeper in the longitudinal direction of the rail sleeper in the case of a one-piece design of the angled guide plate, according to a preferred embodiment of the invention, it is provided that the angled guide plate has an elongated hole extending from the upper side to the lower side, the longitudinal axis of the elongated hole extending parallel to the rib-shaped portion, wherein the elongated hole is preferably formed between the support shoulder and the contact surface. The adjustability of the angled guide plate relative to the rail sleeper is determined by the length of the elongated hole.

[0014] The two-part design of the angled guide plate can preferably be realized in such a way that the first part carries or is formed by a rib extending parallel to the rail-side contact surface, and the second part has the rail-side contact surface, wherein the first part can be moved along the guide surface on the second part. Thus, the rail-side contact surface can be adjusted in the vertical direction (i.e. perpendicular to the longitudinal direction of the rail) by moving the first part with the ribs of the first part in grooves extending 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 displacement direction.

[0015] The available movement distance of the first part and the acute angle of the guide surface relative to the contact surface determine the possible adjustment distance of the second part perpendicular to the longitudinal direction of the track. However, the movement distance of the first part is particularly limited by the length of the groove constructed in the sleeper. In addition, the acute angle relative to the contact surface cannot be selected to be arbitrarily steep, because this will require excessive space requirements transverse to the longitudinal direction of the track. In order to realize the largest possible adjustment distance of the second part perpendicular to the longitudinal direction of the track with a small space requirement, the first part and the second part preferably respectively carry at least two guide surfaces extending at an acute angle to the contact surface of the track side, along which the first part can move at the second part, wherein the guide surfaces of the respective parts are arranged successively and perpendicularly to the movement direction and offset from each other. The guide surfaces at the first part are preferably spaced farther apart from each other in the longitudinal direction of the track by notches in succession compared to the preferably longer guide surfaces at the second part. This allows, without increasing the space requirement perpendicular to the longitudinal direction of the track, to implement the guide surface with a steeper angle relative to the contact surface of the track side. In particular, a small space requirement along the track is achieved here, and limited travel distances are sufficient in laterally closed grooves that do not extend over the entire sleeper width, so that standard concrete sleeper sets already mounted on the rails can continue to be used or be retrofitted with the angled guide plates according to the invention.

[0016] According to another preferred embodiment, it is provided that the first part and the second part have mutually cooperating form-fitting elements acting transversely to the displacement direction, wherein the form-fitting element is 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 a form-fitting element or groove facilitates adjustment of the second part of the angled guide plate in both directions, i.e. away from the rail and towards the rail, because the first part and the second part are held together in a form-fitting manner, and when the rib is displaced in the groove, the first part facing the rail is also pulled back again in interconnection via the groove / pin or projection.

[0017] In order to allow a displacement of the second part of the angled guide plate transversely to the rail when clamping screws anchored in the sleepers are arranged, preferably an elongated hole extending from the top to the bottom is also provided, the longitudinal axis of which runs perpendicularly to the rail-side contact surface.

[0018] According to a preferred development of the invention, the acute angle is 5-20°, preferably 10-13°. This allows the angular guide plate to be adjusted laterally relative to the base in such a way that a change in the track gauge of at most 5 centimeters is obtained. Furthermore, in a preferred development, in order to achieve this even with a narrowly limited predetermined travel path, the acute angle can be set correspondingly larger for guide surfaces that are arranged offset from one another in the direction of travel and perpendicular to the direction of travel.

[0019] In order to achieve the greatest possible displacement path with a limited extension of the groove, it can advantageously be provided that the angled guide plates have a greater width than the ribs.

[0020] The ribs can have a trapezoidal or circular cross section. Compared with a circular cross section, a trapezoidal or even rectangular cross section of the ribs or of the correspondingly shaped grooves has the advantage that the locking shoulder otherwise provided on the sleeper can thereby be optimally replaced.

[0021] In order to support the clamping spring on the upper side of the angled guide plate in the following manner, i.e., to fix the clamping spring to prevent it from sliding off the rail foot, the angled guide plate preferably has a supporting shoulder. The supporting shoulder is particularly configured in the end region of the angled guide plate facing away from the abutment surface and can extend parallel to the abutment surface.

[0022] The position of the clamping spring on the angled guide plate can preferably be fixed particularly well in that the supporting shoulder is delimited on its side facing the contact surface by a channel-shaped recess for engaging at least one rear supporting section of the clamping spring.

[0023] With regard to the position of the ribs on the underside of the angled guide plate, a preferred development of the invention provides that the channel-shaped recess and the ribs intersect each other, wherein the intersection point is preferably arranged at the level of the elongated hole, i.e. approximately in the center of the angled guide plate. In conjunction with a clamping spring having two rear support sections, this can achieve a configuration in which, in the installed state of the clamping spring, the two rear support sections of the clamping spring engage in the channel-shaped recess on both sides of the center, wherein, viewed in a top view, the bearing points of the support sections on the angled guide plate are located on opposite sides of the ribs. This has the effect that the ribs are ideally secured against lifting when loaded. At the same time, this results in a relative position between the ribs and the channel-shaped recess that results in a particularly narrow and material-saving embodiment of the angled guide plate.

[0024] It can preferably be provided that the clamping spring is also supported in the front region on the angled guide plate in the installed state. For this purpose, it is advantageously designed such that a bearing surface for supporting at least one front support section of the clamping spring is provided on the upper side of the angled guide plate in the end region facing the contact surface.

[0025] In order to enable the clamping spring to cooperate with the angle guide plate in a form-fitting manner in different displacement positions and thus fix the displacement position, it is preferably provided that the bearing surface has a plurality of parallel grooves extending transversely to, and in particular perpendicularly to, the abutment surface, and that the at least one front support section of the clamping spring engages in the grooves for fixing the position in one of the plurality of displacement positions of the angle guide plate.

[0026] According to a second aspect of the present invention, a fastening system for fastening a rail for a rail vehicle to a sleeper is provided, the fastening system comprising an angular guide plate according to the first aspect of the present invention which can be arranged on the sleeper, and the sleeper having at least one groove extending transversely to the longitudinal direction of the sleeper, wherein in the installed state, a rib-shaped portion of the angular guide plate engages in the groove in a manner that can be moved in the longitudinal direction of the groove, and further comprising a clamping spring having at least one supporting section that can be supported on a supporting surface of the angular guide plate and at least one rail holding section, wherein in the installed state of the clamping spring, a pressing force can be applied to the rail foot of the rail via the rail holding section.

[0027] In order to provide the largest possible contact surface 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 therefore advantageously also has a correspondingly dimensioned trapezoidal cross-section so that the rib can be accommodated in the groove displaceably and with as little play as possible.

[0028] As already explained in connection with the first aspect of the invention, the configuration of the angled guide plate with the ribs formed on the underside according to the invention only requires the formation of the groove on the sleeper, but further processing of the sleeper is not required, so that in particular the support levels of the rail and the angled guide plate can remain the same. A step-free configuration is understood here to mean that no stop shoulder for lateral support or guidance of the support area beyond the rail on the sleeper is molded or formed. In other words, the surface area of ​​the sleeper adjacent to the groove is located 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.

[0029] In particular, when the sleeper is manufactured as a precast concrete part in one piece, the groove can be produced later by milling, for example. The groove can also be pressed during sleeper production by a molding body that is inserted into the formwork for molding the precast concrete part. This allows very simple production of sleepers with block-like standard shapes without stepped or sunken surface areas. The embodiments according to the invention are also suitable for sleepers based on plastic.

[0030] In this regard, a preferred embodiment provides that the groove extends over the entire width of the sleeper. This leads to a further simplification of the manufacturing process and also allows the largest possible adjustment range of the angled guide plate relative to the sleeper.

[0031] As is known per se, the fastening system preferably also comprises a clamping screw which can be anchored through the elongated hole of the angled guide plate in a hole of the sleeper in order to clamp the clamping spring.

[0032] The clamping spring can here have at least one rear supporting section which can be supported against a supporting shoulder of the angled guide plate.

[0033] The clamping spring can also have two rear support sections and the angled guide plate can have corresponding support surfaces on which the support sections rest in the installed state of the clamping spring, wherein the support surfaces are arranged on opposite sides of the rib when viewed in plan view.

[0034] Furthermore, the clamping spring can have at least one front supporting section which, in the installed state, can be supported on a contact surface of the angled guide plate which is arranged in the end region facing the contact surface.

[0035] The clamping spring is preferably designed essentially in an "ω" shape, the free ends of which each form a rail retaining section and preferably the middle section thereof projects beyond the rail foot by a certain distance from the front support section. The middle section advantageously forms an overload protection device, which takes effect when the rail foot rises by an amount corresponding to the aforementioned distance due to excessive loads and prevents the rail foot from rising further and thus also prevents further deformation of the rail retaining section.

[0036] In the case of a design with a two-part angled guide plate, an alternative design of the clamping spring can preferably be used which is similar to an “e” shape, except that the end section of the “e” shape has an additional inwardly directed curvature.

[0037] Such a clamping spring preferably comprises a U-shaped main section having a U-shaped bend, a first leg arranged at one side of the U-shaped bend, and a second leg arranged at the other side of the U-shaped bend, wherein a support or retaining section which is bent inwardly in a hook-like manner and can be supported on a clamping device is constructed on the first leg, and an end section which is bent toward or away from the support or retaining section is constructed on the second leg, wherein the U-shaped bend constructs a torsion section so that a clamping force can be applied to the rail system element via the bent end section.

[0038] The bent end section here forms the region of the clamping spring via which the clamping force is applied to the rail foot. When a torsional force is applied by the bent end section to the torsional section formed by the U-shaped bend of the clamping spring, the hook-shaped holding section starting from the first leg of the U-shape serves to be held in a clamped state by the clamping screw. The hook-shaped holding section is bent inwards here, which can be understood as meaning that the hook is bent between the two legs of the U-shape. Preferably, the hook-shaped support or holding section forms the end of the clamping spring on the side of the first leg, i.e. the free end of the region bent into the hook is located between the two legs of the U-shape. The holding section can be at least partially supported on a base, for example on an angled guide plate according to the invention, and thus corresponds to the supporting section.

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

[0040] Preferably, the hook-shaped bend of the supporting or retaining section has a bend of substantially 180°, so that the free end region of the supporting or retaining section runs substantially parallel to the first leg, at least in sections.

[0041] Preferably, in plan view, an imaginary extension of the angled end section overlaps the hook-shaped bend.

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

[0043] Preferably, in the unloaded state, the second leg extends at an acute angle relative to a common plane of the supporting or retaining section and the first leg and is preferably located 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 at the U-shaped bend.

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

[0045] According to another aspect of the invention, a sleeper for use in a fastening system according to the invention is provided, the sleeper comprising an upper side with bearing areas arranged at intervals of the track gauge for each rail, wherein a groove extending at an acute angle to the longitudinal direction of the rail is formed on both sides of each bearing area, in which a rib-shaped portion formed at the lower side of the angled guide plate can be received in a manner that it can move in the longitudinal direction of the groove. The groove extending at an acute angle to the longitudinal direction of the rail can also be defined as a groove extending at an acute angle to the longitudinal direction of the sleeper, because the longitudinal direction of the rail extends perpendicularly to the longitudinal direction of the sleeper.

[0046] As already explained in connection with the second aspect of the invention, the groove extends over the entire width of the sleeper. Alternatively, however, the groove can also be configured in such a way that it ends at both ends at a certain distance from the respective side surfaces of the sleeper.

[0047] Advantageously, the sleeper has no further processing, apart from the groove and any holes for anchoring the clamping screws, and is designed in particular such that, apart from the inclined groove, the sleeper is designed without a step on the upper side. This saves a great deal of additional material expenditure for a support shoulder or step that is raised relative to the support area of ​​the sleeper with respect to the rail. In particular in the case of concrete sleepers, this is accompanied by a positive influence on the CO2 balance.

[0048] In this case, a step-free design is understood to mean that no stop shoulder is integrally formed or formed on the sleeper beside the angled guide plate, which extends beyond the bearing area of ​​the rail for lateral support or guidance on the sleeper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] exist Figure 1 and Figure 2 A sleeper 1 is shown, on which a rail 2 is placed. The rail foot 3 of the rail 2 is fixed in position on both sides of the rail 1 by an angled guide plate 4, which has a rail-side contact surface 5 for the rail foot 3. In order to clamp the rail foot 3, a clamping spring 6 is provided on both sides, which is held in a clamped state by a clamping screw 7. The clamping spring 6 is essentially designed in an "ω" shape and has two rear support sections 8, which are supported on the support shoulders 9 of the angled guide plate 4 and engage in a channel-shaped recess 10. The free ends of the clamping spring 6 each form a rail holding section 11, which applies a clamping force to the rail foot 3 of the rail 2. The clamping spring 6 also has two front support sections 17 ( Figure 2 ), the front support section is placed on the supporting surface 12 ( Figure 3 ) on the support surface, which has a plurality of parallel grooves 13 ( Figure 3 ), the front support section 17 of the clamping spring 6 engages in the groove. The clamping spring 6 also has a middle section 14, which starts from the front support section 17 of the clamping spring 6 and exceeds the rail foot 3 by a certain distance, in order to thereby form an overload protection.

[0051] A rib 15 is formed on the underside 19 of the angled guide plate 4, which extends obliquely to the longitudinal direction of the rail and engages movably in the groove 16 of the sleeper 1. As a result, the angled guide plate 4 can be moved along the inclined guide surface 41 ( Figure 4 and Figure 6 ) is movable relative to the sleeper 1 and relative to the rail 2, which allows adaptation to different track gauges or track positions.

[0052] exist Figures 3 to 6 In the embodiment, the angled guide plate 4 is shown alone, and now the elongated hole 18 can be seen in addition, whose longitudinal axis extends parallel to the rib 15. The elongated hole 18 is formed between the supporting shoulder 9 and the contact surface 5. Figure 5As indicated by dashed lines in the top view of the , the channel-shaped depression 10 and the rib 15 intersect one another, wherein the intersection point 24 is arranged at the height of the slot 18 in the top view, in particular approximately in the center of the angled guide plate 4 with respect to the length of the angled guide plate 4. The center line of the channel-shaped depression 10 is denoted by 21, the center line of the rib 15 is denoted by 22, and the center line of the angled guide plate 4 is denoted by 23. In the top 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 section 8 of the clamping spring 6 rests in the center position of the clamping spring 6, are denoted by 25, and it can be seen that the support surface 25 is arranged on opposite sides of the rib 15 (i.e. the center line 22) when viewed in the top view.

[0053] exist Figure 7 The sleeper 1 is presented in isolation in FIG. 1 and it can be seen that, apart from the groove 16 and the hole 20 for accommodating the clamping screw 6 , the sleeper 1 has no surface machining, sunken areas, recesses and / or steps.

[0054] Figure 8-11 A modified embodiment of the fastening system is shown, in which the angled guide plate 4 is constructed in two parts and an alternative embodiment of the clamping spring 34 is used. Fig. 9 and 11 As can be seen in the figure, the angular guide plate 4 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 in the assembled state, wherein the rib 15 preferably has a trapezoidal cross section and is provided with at least one guide surface 28. The first and second parts 26, 27 can be arranged along guide surfaces 28, 29 ( Fig.11 ) so that the corresponding track gauge can be adapted. The second part 27 also includes a plate-shaped support element 30, on which a clamping spring 34 is placed and which overlaps the first element 26. Fig.11 As can be seen in the figure, the plate-shaped supporting element 30 has at its lower side at least one inclined guide groove 31, into which a guide pin or a projection (not shown) constructed on the upper side of the first element 26 engages in order to hold the two components 26, 27 together, in particular in the unloaded state.

[0055] It can also 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 in the installed state of the exemplary clamping spring 34. The through hole 18 is designed as an elongated hole perpendicular to the longitudinal direction of the rail. For the lateral guidance of the clamping 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 clamping spring 34. In addition, a projection 33 is used to guide the clamping spring 34, which projection is arranged between the first leg 36 of the clamping spring 34 and the free end 40 of the supporting or retaining section 38 (see Figure 12-15 ).

[0056] The clamping spring 34 can be Figure 8 , and a pre-installation position in which the clamping spring 34 does not overlap the rail foot. The design is such that the screw 7 does not have to be loosened in order to move the clamping spring 34 from the pre-installation position into the final installation position. For example, the movement can be carried out by means of a lever-like tool.

[0057] In accordance with Figure 8-11 The clamping spring 34 used in the fastening system is described below according to Figure 12-15 Described in more detail. The clamping spring 34 comprises a U-shaped main section having a U-shaped bend 35, a first leg 36 arranged at one side of the U-shaped bend 35, and a second leg 37 arranged at the other side of the U-shaped bend 35, wherein a support or holding section 38 bent inwardly in a hook shape and capable of being supported on a clamping device or an angled guide plate is configured on the first leg 36, and an end section 39 bent toward or away from the support or holding section 38 is configured on the second leg 37. The holding section 38 comprises a free end 40.

[0058] exist Fig.14 It can be seen in FIG. 3 that the angled end section 39 is slightly inclined upwards, so that an acute angle α is present between the angled end section 39 and the plane of the support or holding section 38 and the first leg 36 .

[0059] exist Fig.15 It can be seen in FIG. 3 that the second leg 37 encloses an acute angle β with the support or holding section 38 and the plane of the first leg 36 .
