Definitions

  • the invention relates to an angle guide plate for fastening rails for rail vehicles on a sleeper using a tension spring that can be supported on the angle guide plate, comprising at least one support surface, in particular 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 Rail and a bottom opposite the top for supporting the angle guide plate on the threshold.
  • 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.
  • the assembly of rails of a track body is usually carried out using a spring element, usually referred to as a tension spring or tension clamp, and a suitable tension element or hold-down device for tensioning 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 clamped against the ground in such a way that it applies the required holding forces via its section resting on the rail base.
  • the spring element is supported on an angle guide plate resting on the threshold, 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 angle 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 transmit the wheel side forces into the sleeper body.
  • the angle guide plate is supported on a support shoulder of the threshold with an end face arranged on the side facing away from the rail.
  • the support shoulder of the threshold and the end face of the angle guide plate that interacts with it run obliquely to the longitudinal direction of the rail, whereby a displacement of the angle guide plate relative to the threshold in the longitudinal direction of the rail allows adaptation to different track widths.
  • the disadvantage of this embodiment is that the angle guide plate and the rail are arranged in a recessed area of the threshold in order to enable the angle guide plate to be supported on the support shoulder of the threshold.
  • the cross section of the sleeper is weakened in the entire contact area of the rail and the angle guide plates and the rail comes closer to the ballast bed, which makes the tamping process more difficult.
  • the threshold In order to avoid these effects, the threshold must be made higher in the rail support area, whereby the support shoulders of the sleeper must also be raised relative to the rail support. This increases the amount of work and material required to produce and/or process the threshold.
  • the present invention therefore aims to overcome the above-mentioned disadvantages and to create, with reduced effort, an angle guide plate and an associated rail fastening system with an associated threshold, which allows the angle guide plate to be displaced relative to the ground in the longitudinal direction of the rail in order to adapt to different track widths, without the need for this one Material and labor-intensive design of the substrate or the angle guide plate is required.
  • an angle guide plate of the type mentioned essentially consists in the fact that a rib is formed on the underside, which can be displaceably received in a groove formed in the threshold, and that one is at an acute angle to the Guide surface running on the rail-side contact surface is provided, so that an adjustment of the rail-side contact surface with a directional component running perpendicular to the contact surface can be achieved by moving the rib in the groove.
  • the adjustment of the angle guide plate along an inclined guide surface is thus achieved by a rib which is formed on the underside of the angle guide plate.
  • a rib which is formed on the underside of the angle guide plate.
  • all that needs to be provided in the subsurface, such as the threshold, is a groove into which the rib engages.
  • the remaining area of the subsurface does not require any processing, and in particular the support level of the rail and the angle guide plate can remain the same.
  • the rib is formed in one piece with the angle guide plate.
  • the angle guide plate can be made in one piece or composed of two separate parts.
  • a first part can have the 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.
  • transverse in relation to a reference direction means that the corresponding direction extends perpendicularly or obliquely to the reference direction.
  • Transverse to the longitudinal direction of the rail means “perpendicular to the longitudinal direction of the rail” or “oblique to the longitudinal direction of the rail”.
  • the one-piece design can preferably be implemented 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.
  • a rib is formed on the underside of the angle guide plate, extending at an acute angle to the rail-side contact surface, which can be displaceably received in the groove formed in the threshold and which carries the guide surface.
  • the tension spring is usually pretensioned by means of a tension screw that can be anchored in the sleeper so that it applies the required holding forces via its section(s) resting on the rail base.
  • the clamping screw passes through the angle guide plate.
  • the angle guide plate has an elongated hole extending from the top to the bottom, the longitudinal axis of which runs parallel to the rib. The adjustability of the angle guide plate relative to the threshold is determined by the length of the elongated hole.
  • 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, the first part being along the guide surface second part can be moved.
  • the adjustment of the rail-side contact surface in the vertical direction, i.e. perpendicular to the longitudinal direction of the rail, is thus carried out by moving the first part with its rib in the groove running parallel to the rail-side contact surface, the first part sliding with its guide surface on the oblique guide surface of the second part and the latter adjusted perpendicular to the direction of displacement.
  • the available displacement path of the first part and the acute angle of the guide surface to the contact surface determine the possible adjustment path of the second part perpendicular to the longitudinal direction of the rail.
  • the displacement path of the first part is limited, among other things, by the length of the groove formed in the threshold.
  • the acute angle to the contact surface cannot be chosen to be as steep as desired, as this would require excessive space transversely to the longitudinal direction of the rail.
  • the first part and the second part preferably each carry at least two guide surfaces which run at an acute angle to the rail-side contact surface, along which the first part can be displaced 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 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 requirement perpendicular to the longitudinal direction of the rail.
  • a small amount of space is required along the rail and a limited displacement path can be achieved in laterally closed grooves that do not extend over the entire sleeper width, so that a standard concrete sleeper set that has already been installed in the track can continue to be used or with the angle guide plate according to the invention can be retrofitted.
  • the first and second parts have form-fitting elements that interact with one another and are effective transversely to the direction of displacement, the form-fitting elements preferably being formed by at least one groove running at the acute angle to the rail-side contact surface and a projection engaging in the groove .
  • Such form-fitting 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-fitting manner and the first part facing the rail when the rib is moved is also withdrawn again in the groove via the grooves/pins or projections.
  • an elongated hole extending from the top to the bottom is preferably also provided, the longitudinal axis of which runs perpendicular to the rail-side contact surface.
  • the acute angle is 5-20°, preferably 10-13°. This allows the angle guide plate to be adjusted laterally relative to the ground in such a way that the track width changes by up to 5 cm. In order to achieve this even with a narrowly specified displacement path, the acute angle can also be provided correspondingly larger in a preferred development when the guide surfaces are arranged one behind the other in the displacement direction and offset from one another perpendicular to the displacement direction.
  • the angle guide plate has a greater width than the rib.
  • 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 that would otherwise be provided on the threshold.
  • 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.
  • 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 trough-shaped recess for the engagement of at least one rear support section of the tension spring.
  • a preferred development of the invention provides that the trough-shaped recess and the rib cross each other, the crossing point preferably being arranged at the level of the elongated hole, i.e. approximately in the middle of the angle guide plate.
  • this enables a design in which the two rear support sections of the tension spring engage in the trough-shaped recess on both sides of the center when the tension spring is in the assembled state, with the support points of the support sections on the angle guide plate in seen from the top view are arranged on opposite sides of the rib.
  • This has the effect that the rib is ideally secured against lifting off under load.
  • there is a relative position between the rib and the channel-shaped recess which results in a particularly narrow and therefore material-saving embodiment of the angle guide plate.
  • the tension spring in the assembled state is also in a front area on the Angle guide plate is supported.
  • 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 top of the angle guide plate.
  • 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 to secure the position engages in one of several displacement positions of the angle guide plate.
  • a fastening system for fastening rails for rail vehicles on a sleeper comprising an angle guide plate which can be arranged on the sleeper according to the first aspect of the invention, and a sleeper which has at least one groove running transversely to the longitudinal direction of the sleeper, in which 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 base of the rail in the assembled state of the tension spring .
  • the rib and the groove have cross sections that correspond to one another. 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 accommodated in the groove with as little play as possible.
  • the inventive design of the angle guide plate with a rib formed on the underside only requires the formation of a groove on the threshold, but otherwise no further processing of the threshold, so that in particular the support level of the rail and the Angle guide plate can remain the same.
  • a stepless design is understood to mean that on the threshold next to the angle guide plate, there are no stop shoulders that project beyond a support area of a rail for lateral support or guidance on the threshold.
  • the surface areas of the threshold 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, for example, be produced subsequently by milling, especially if the threshold was manufactured as a prefabricated concrete part in one piece.
  • the groove can also be embossed during the production of the threshold by a molded body inserted into the formwork for shaping the precast concrete part. This allows an extremely easy manufacture of the threshold with a standard block-like shape without stepped or recessed surface areas.
  • the design according to the invention is also suitable for plastic-based thresholds.
  • a preferred embodiment provides that the groove extends over the entire width of the threshold. This leads to a further simplification of the manufacturing process and also allows the largest possible adjustment range of the angle guide plate relative to the threshold.
  • the fastening system preferably further comprises a tensioning screw, which can be anchored in a hole in the threshold passing through the elongated hole in the angle guide plate in order to tension the tension spring.
  • the tension spring can have at least one rear support section, which can be supported against the support shoulder of the angle guide plate.
  • 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 in the assembled state of the tension spring, the support surfaces being arranged on opposite sides of the rib when viewed in plan view.
  • the tension spring can have at least one front support section, which in the assembled state can be supported on the support surface of the angle guide plate arranged in the end region facing the contact surface.
  • the tension spring is preferably essentially " ⁇ "-shaped, the free ends of which each form the rail holding section and preferably the middle section of which projects beyond the rail base at a distance starting from the front support sections.
  • the middle section advantageously forms an overload protection, which comes into effect when the rail foot rises due to excessive load by an amount corresponding to the distance mentioned, and which prevents the rail foot from rising further and, in connection with this, further deformation of the rail holding sections.
  • 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, inward bend.
  • Such a tension spring preferably comprises a U-shaped main section which has a U-bow, a first leg arranged on one side of the U-bow and a second leg arranged on the other side of the U-bow, with a hook-shaped inwardly bent support or holding section which can be supported on a hold-down device and on the second leg an end section which is bent towards or away from the support or holding section is formed, the U-bend forming a torsion section so that over the bent end section a hold-down force can be applied to the track body element.
  • the bent end section forms the area of the tension spring through which the holding force is applied Rail foot is applied.
  • the hook-shaped holding 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 by the bent end section on the torsion section formed by the U-bow of the tension spring.
  • the hook-shaped holding section is bent inwards, which is to be understood as meaning that the hook is bent between the two legs of the U-shape.
  • the hook-shaped support or holding section on the side of the first leg forms the end of the tension spring, ie the free end of the area bent into a hook lies between the two legs of the U-shape.
  • the holding 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.
  • the bent end section preferably runs at an angle of 80-100°, preferably approximately 90°, to the second leg.
  • a hook arch of the support or holding section preferably has a substantially 180° bend, so that a free end region of the support or holding section runs essentially parallel to the first leg, at least in sections.

  • the groove running at an acute angle to the longitudinal direction of the rail can also be defined as a groove running 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.
  • the groove can extend over the entire width of the threshold.
  • the groove can also be designed in such a way that it ends at both ends at a distance from the respective side surface of the threshold.
  • the threshold has no further processing with the exception of the groove and any holes for anchoring clamping screws and is in particular designed in such a way that the threshold is continuously formed on the top with the exception of the oblique grooves.
  • This largely saves additional material costs for supporting shoulders or steps of the threshold that are too high relative to the support area of the rails. This has a positive effect on the CO2 balance, especially with concrete sleepers.
  • a stepless design is understood to mean that on the threshold next to the angle guide plate, there are no stop shoulders that project beyond a support area of a rail for lateral support or guidance on the threshold.
