COMPLETE SPECIFICATION STANDARD PATENT Invention Title: SEAT FOR A TRACK RAIL a a a a a a.
The following statement is a full description of this invention, including the best method of performing it known to us: GH REF: P24858-C:JDF:RK Seat for a Track Rail The invention relates to a seat for a track rail.
Rail seats with an elastomer rubber contour for reducing structure-borne noise or secondary airborne noise, or to create the necessary superstructure resilience in traffic connected with rails, are known in a variety of forms of embodiment.
Rail seats of this kind are resilient rubber/metal compounds which do not have any continuous metallic connection between the rail and the sub-surface.
Rail seats of this kind usually consist of an upper plate and a frame. Both structural parts are connected permanently to one another via a rubber contour which is vulcanised on. This means: the rail seat of this type is in one piece. Linear spring characteristics over a wide load region are sought after. Variants with a two-stage spring characteristic are also known.
On the traditional rail seats (see for example DE-40 31 540), the fastening means of the rails on the rail seat and the fastening means of the rail seat to the subsurface are usually arranged axisymmetric to one 3 another. This leads of necessity to relatively large structural shapes. This not only has the disadvantage that the rail seats are thus relatively heavy and expensive but a sufficiently large-area sub-surface must be available or be provided for fastening the rail seat to the track body.
*5 A rail seat described in DE-PS 34 36 054 consists substantially of an upper plate described as a rib plate, a resilient rubber contour and a base plate.
The base plate is configured like a frame or a trough and has on each side edge an edge strip extending vertically upwards and fixing the elastic rubber contour at the side and thus forming a frame. The points for fastening the rails are arranged symmetrically on a middle line of the rib plate running transversely. Through an offset arrangement of the fastening holes provided for attaching the seat to the sleepers or the like, there is no space-saving effect.
Preferably, the invention has a construction which is as small as possible with small seat dimensions.
In accordance with an aspect of the present invention, there is provided a track rail seat including an upper plate and a frame which are permanently connected to one another via a vulcanised-on rubber contour, and in which bores for receiving devices which fasten the rail seat Ste97sub-surface' are arranged offset 3A beside a centre line running in a transverse direction of a rail seat, wherein the geometry of the rail seat, seen in plan view, is asymmetric (not axisymmetric), an axis of the upper plate which passes through fastening points of the rail is such that there is rotational symmetry in relation to the axis, and the rail is attachable to an upper plate of the rail seat at diagonally opposite locations by clamps, the bores being positioned beside the rail fastenings such that the clamps and the rail seat fastening points are in each case diagonally opposite in pairs, the rubber contour including a plurality of deformation bodies which differ in respect of their shape, size and/or arrangement, the deformation bodies being arranged in quadrants, each quadrant being respectively 15 disposed below a corresponding one of the bores or the fastening points, and the deformation bodies in each quadrant being arranged so as to provide uniform springing and reliable enduring of loads on the rail seat.
9 20 In modification of a rail seat of this type, which 9 consists substantially of a frame, an upper plate and a rubber contour located between same, the geometry of 99 the upper plate of the rail seat according to the invention is asymmetric (not axisymmetric), the bores R t e 4 of the rail seat and the fastening points of the rails being opposite one another cross-wise, one bore hole coming to lie respectively beside one track fastening point.
Preferred embodiments and developments are mentioned in the secondary claims.
The track seat according to the invention has no axial symmetry as is otherwise usual. There is only a central symmetry, to put it more accurately, a rotational symmetry, i.e. a congruence in the same direction (in which the two halves can be led over into one another by being rotated). Whilst with the longitudinal axis of the rail seat there is normally axial symmetry, the axis of the rotational symmetry, i.e. the congruence now lies rotated by an angle a out of the longitudinal axis the rail axis) Because the axis of both rail seat halves which connects the bore holes is configured congruent in *.25 -outline, as well as the track fastening screws, the bores for the fastenings to the sub-surface (anchors, threaded bolts or rail screws with plastic dowels) are also arranged very close to the rail, and this means that the whole rail seat can be configured very small.
In addition to this, the bores are designed as elongated holes and thus the fastening may be adjusted sideways by means of corresponding toothed discs. This leads to a wide range of possible uses (concrete track
I,
carrier, timber sleeper, longitudinal concrete sleeper and transverse sleepers, steel girders). Through the track seat according to the invention, fastening to the sub-surface free of transverse force is guaranteed.
Not only the bore for the attachments which fasten the seat in the sub-surface, but also the screw chamber cams for fixing the rail are arranged offset on the rail seat.
In order, with the resulting offset fixing, reliably to prevent any twisting of the rail, an additional protection against twisting is applied on the side facing the clamp on the upper plate) The rail seat according to the invention is conceived in such general terms that it is in a position, with corresponding inserts, to receive rail bases of o• different widths.
The edge region of the frame has a shape which is *25 offset. Here the frame grasps round the upper plate at the two outer edge portions, and this produces optimal insurance against lifting off.
*i On its lower side, the rubber contour has knobs which are configured differently. In this way the spring characteristic can be set in an optimum way dependent upon the load.
With the asymmetric design of the rail seat, through a specific arrangement of the deformation bodies on the underside of the rail seat, a deliberately designed distribution of rigidity below the surface may be achieved.
Although greater tilting moments occur in- the upper plate, because of the asymmetric configuration of the rail seat and the more compact structural size which may thereby be achieved, through the special arrangement and design of the rubber knobs, high tilting resistance may be achieved.
The rail seat is laid out in such a way that different rubber contour variants (knob contours) may be realised 20 on the lower side. The respective rubber contour variant depends on the desired (overall) seat rigidity.
Thus the four fields below the upper surface have a largely uniform rigidity.
25 Through the design of the rail seat according to the invention, an exact setting of the seat rigidity is possible with the available variable Shore A hardnesses o f the rubber and taking into account the usual hardness tolerances of rubber.
Proceeding from different base configurations, with this rail seat, all the ranges of rigidity which are relevant in practice may be covered. For this purpose, 7 three different rubber contours are preferably available, which differ in the geometry of their crosssection and in their cross-section surfaces as well as in the arrangement of the knobs below the upper plate.
All the characteristics of this rail seat lead to a favourable combination of low seat dimensions, low weight, low manufacturing costs and characteristics which may be varied over a wide range such as spring rigidity and positioning in the installed state.
The rail seat according to the invention is explained below in greater detail with the aid of the enclosed drawings.
*o* These show: Fig. 1 a plan view of a rail seat according to the invention; Fig. 2 a side view of the rail seat according to 25 Fig. 1 in the longitudinal axis of the rail; Fig. 3 a side view of the rail seat transverse to the longitudinal direction of the rail; Figs.4a and 4b in detail, the toothed disc as well as the opposed toothed wheel work on the frame: Fig. 5 a plan view of the rail seat showing particularly the rubber contour and leaving out the clamps; Fig. 6 a cross section according to line A A in Fig. Fig. 7 a longitudinal section through the rail seat according to the line B B in Fig. The track rail seat 2 according to the invention is a so-called one-piece rail seat 2. It consists of a metallic frame 4 and a similar upper plate 6, which are connected together via a vulcanised-on rubber contour (elastomer) 8 (Fig. 6) The geometry of the upper plate 6 of the rail seat 2 is asymmetric (not axisymmetric) (Fig. the axis 12 of *o00 the upper plate 6 being rotated out of the rail seat longitudinal axis e.g. by a 570 (30° a .900), i.e.
25 there is rotational symmetry in relation to the axis 12.
The upper plate has a rail channel 40. The rail is attached at diagonally opposite points 14 by clamps 18 to the rail seat's upper plate 6. Through a variable design of the upper plate 6, different types of clamps 18 may be used here.
9 With the use of corresponding inserts (spacer blocks) the rail seat 2 is suitable for receiving rails 16 with base widths of up to 150 mm.
On the points of the rail channel 40 at which the rails are not guided through the receiving means for the clamps 18, the rail 16 is guided by webs (protection against twisting) 20, running at the side in the longitudinal direction on the upper plate 6. In this way, twisting of the rail 16 out of the longitudinal axis of the seat is prevented.
The surface of the upper plate 6 on which the rail rests is slightly raised in relation to the upper edge of the frame 4 and thus makes it possible for the upper plate 6 to be sprung in when the rail 16 is laid on it.
The upper plate 6 has a frame 4 which is closed all i round.
On the frame 4 there is located a so-called device for o 25 preventing lifting off 22, which prevents tilting or
*D*
lifting off of the upper plate 6.
The bores 24 for receiving the devices which attach the seat to the sub-surface threaded bolts, rail screws with plastic dowels, rail anchors) are positioned beside the rail fastenings 18 so as to save space. This leads to a wide range of possible uses, i.e. also on timber sleepers and concrete sleepers.
This attachment to the sub-surface can be carried out in such a way that it makes possible the sideways adjustability of the rail seat 2 with the use of a toothed disc 26 and a corresponding opposed toothed wheel work 28 on the frame 4(Figs. 4a/4b).
The frame 4 lies completely on the sub-surface and diverts into the sub-surface all the horizontal loads which occur via static friction forces. The fastening elements rail screws) of the rail seat 2 thus do not have to-receive any transverse forces.
The rubber contour 8 (Figs. 5/6/7) has a plurality of deformation bodies/rubber knobs 30 which differ in 20 their shape, size and/or arrangement. Through this special design of the rubber contour 8 arranged below the upper plate 6, uniform springing and reliable enduring of all loads which occur is guaranteed.
00 o0 25 Two diagonally opposite quadrants (34, 38) each have a larger surface whilst the two other quadrants (32, 36) are smaller. The size and number of the knobs associated with the quadrants are now configured in such a way that the total rigidity of the respective quadrants is the same. The concern that'the upper plate of the rail seat could tend to tilt because of asymmetry conditioned by its construction is thus completely unfounded.
11 The stability of the rail seat is improved by the arrangement of the knobs. In particular, both the rail seat 2 and the rail 16 are thus protected from harmful stress, and the accuracy of the line of the track is preserved.
The height of the rubber knobs is preferably hknob 12 mm and the thickness of the rubber layer disposed above same is preferably hiayer 9 mm (constant in each case).
These values could however be varied within narrow o limits.
Through varying the rubber contour 8, the rail seat 2 can be adapted to the respective current stress. This may be further influenced by the individually .oo. adjustable properties of the elastomer 8 which is used.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprising" is used in the sense of "including", i.e. the features specified may be associated with further features in various embodiments of the invention.
