Definitions
- 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 support shoulder, formed on an upper side of the angle guide plate, for supporting the tension spring Rail-side contact surface for a rail foot of the rail and an underside 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.
- a tension spring or tension clamp usually referred to as a tension spring or tension clamp
- a suitable tension element or hold-down device for tensioning the spring element.
- a hold-down device is usually a screw that can be anchored in the sleeper, through which the spring element is braced 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: To secure the rail on the support surface of the sleeper against displacement in the transverse direction of the track and to transfer 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.
- an angle guide plate of the type mentioned 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 one is at an acute angle A guide surface running to 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 displacing 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.
- the subsurface such as. B.
- the threshold only needs to be provided with 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 preferably 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 be formed on its underside Have a rib and a second part is 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 perpendicular or oblique to the reference direction.
- Transverse to the longitudinal direction of the rail thus 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 top view extends at an acute angle to the rail-side contact surface.
- a rib is formed on the underside of the angle guide plate, which extends at an acute angle to the rail-side contact surface, which rib can be displaceably received in the groove formed in the threshold and which carries the guide surface.
- the tension spring is usually pre-tensioned 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 is parallel to the Rib runs, with preference being given to the elongated hole is formed between the support shoulder and the contact surface.
- 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 running along the guide surface on the second part can be moved.
- the adjustment of the rail-side contact surface in the vertical direction, i.e. H . 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 adjusting the latter 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 each preferably carry at least two guide surfaces running at an acute angle to the rail-side contact surface, along which the The first part is displaceable on the second part, the guide surfaces of the respective part being 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 at a steeper angle to the rail-side contact surface without increasing the space required 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 set of concrete sleepers that has already been installed in the track can continue to be used. can be retrofitted with the angle guide plate according to the invention.
- 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 having at least one groove running at an acute angle to the rail-side contact surface and one engaging in the groove Projection is formed.
- Such form-fitting elements or The grooves make it easier to adjust the second part of the angle guide plate in both directions, i.e. H . away from the rail and towards the rail, since the first and second parts are held together in a form-fitting manner and the first part facing the rail moves over the when the rib is moved in the groove Grooves/pins or projections are also withdrawn together.
- an elongated hole extending from the top to the bottom is preferably 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 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 engaging at least one rear support section of the tension spring.
- a preferred development of the invention provides that the trough-shaped depression and the rib cross each other, with the crossing point preferably at the level of the elongated hole, i.e. H . 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 seen in plan 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 depression which is particularly narrow and therefore material-saving design of the angle guide plate.
- the tension spring is also supported in a front area on the angle guide plate in the assembled state.
- 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 The tension spring intervenes to secure the position 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 which engages the rib of the angle guide plate in the assembled state so as to be displaceable in the longitudinal direction of the groove, and further comprising a tension spring which can be supported at least on the support surface of the angle guide plate Support section 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.
- 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 design according to the invention 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 here to mean that on the threshold next to the angle guide plate, no stop shoulders are formed or formed on the threshold for lateral support or guidance, which protrude beyond a support area of a rail.
- the surface areas of the threshold adjacent to the groove lie on both sides of the groove, i.e. H . on the side facing the support area for the rail and on the side facing away from the support area for the rail, in the same plane.
- the groove can z.
- 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 foot at a distance starting from the front support sections.
- the middle section advantageously forms an overload protection z which has the effect occurs 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, associated 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.

Holding section and on the second leg for support or. Holding section towards or away from this bent end section is formed, 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.
- the bent end section forms the area of the tension spring through which the holding force is applied to the rail base.
- 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 holding section can be at least partially on a surface such as. B. support the angle guide plate according to the invention and thus corresponds to a support section.
- 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.
