Description

Track rail seat

The present invention relates to a seat for a track rail.

Background of the Invention [0002] Rail seats of an elastomeric rubber of an appearance that reduce noise due to structure or incidental air or create elasticity of the required superstructure of a vehicle connected to the rail are already known in various forms of embodiment. Rail sheets of this kind are rubber and metal compounds, which do not have any continuous metal connection between the rail and the bottom surface.

Rail seats of this kind are usually composed of a top plate and a flame. These structural parts are permanently connected to each other by vulcanized rubber contours. This means that this type of rail seat is in one piece. The linear spring characteristics for a wide range of loads can be seen later. In addition, variants of two-stage spring characteristics are known.

On a conventional rail seat (example DE-40 31 540), the fastening means of the rail on the rail seat and the fastening means of the rail seat to the lower surface are usually aligned axially with respect to each other. This essentially results in a relatively large structural form. Accordingly, this has the disadvantage that the rail seat is relatively heavy and expensive, as well as the disadvantage that a sufficiently large bottom surface must be provided to fasten the rail seat to the track body.

DE-PS 34 46 36 054 consists essentially of the top plate, the elastic rubber outline and the base plate described as rib plates. The base plate is arranged like a flame or trough and has an edge strip that rises vertically on each side edge and secures the rubber contour on the side to form a flame. The fastening points of the rails are arranged symmetrically on the center line with rib plates extending across. An offset device of the fastening hole is provided to attach the seat to the sleeper, but there is no space saving effect.

It is an object of the present invention to provide a structure constructed as small as possible in sheet size.

In a variant of the rail seat of the type consisting of a flame, a top plate and a rubber contour positioned between them, the shape of the top plate of the rail seat according to the invention is symmetrical (but not axially symmetrical) and the bore of the rail sheet. And the fastening points of the rails are staggered symmetrically with each other, and one bore hole is placed next to one orbital fastening point.

Track sheets according to the invention are typically not axisymmetric. It is just central symmetry, and more precisely rotational symmetry, for example congruent in the same direction (the two halves can be rotated on top of each other). It is axially symmetrical with respect to the longitudinal axis of the rail seat, but with respect to the rotational symmetry axis, for example, it rotates by an angle α from the longitudinal axis and is joined.

Since the axes of half of the rail seats connected to the bore holes are arranged to be jointed with outlines, not only the track fastening screws but also the rail screws with anchors, threaded bolts or plastic dowels that are fastened to the lower surface. ) Is also aligned very close to the rail and this means that the entire rail seat can be placed very small. In addition to this, the bore is designed as an elongated hole and accordingly the fastening may be adjusted laterally by means of the corresponding toothed disc. It is used in the widest possible range (concrete track carrier, wood sleeper, longitudinal concrete sleeper, transverse sleeper, river girder) orbit sheet according to the present invention, but on the lower surface where no transverse force is applied. Fastening is guaranteed.

The attachment bore for fastening the seat in the bottom surface, as well as the screw chamber hem for securing the rail, are aligned to offset on the rail seat.

By means of offset fixing, in order to reliably prevent warping of the rail, additional protection against warping on the side is applied to face the clamp (eg on the upper plate).

Rail seat, which is a general term according to the present invention, means that the rail seat is inserted to correspond to the rail base of different widths so as to be provided at an appropriate position.

The edge area of the flame has a 90 ° offset shape. Here, the flames are fixed around the top plate at the two outer edge parts and this ensures that they rise optimally.

On its lower side, the rubber contour has handles arranged differently. In this way the spring characteristics are set in an optimal way according to the load.

With the symmetrical design of the rail seats, due to the specific alignment of the deformable body on the underside of the rail seats, a distribution of strength which is preferably considered below the surface is achieved.

Although greater warp forces occur in the top plate, due to the symmetrical arrangement of the rail seats and the smaller structure size that may thus be achieved, due to the specific alignment and design of the rubber handles, high warp resistance may be achieved.

The rail seat is designed in such a way that other rubber contour variants (handle contours) may be implemented on the lower face. Each rubber contour variant depends on the desired (total) sheet strength. Accordingly, the four zones have a large uniform strength.

In the design of the rail seat according to the invention, it is possible to set the sheet strength precisely with the useful variable Shore A hardness of the rubber and taking into account the conventional hardness tolerance of the rubber.

Another base arrangement is carried out, and in this rail seat, practically all ranges of the appropriate strength are covered. For this purpose, preferably, three different rubber contours differing in their cross-sectional geometry and cross-sectional surface, as well as in alignment of the handle under the top plate.

All properties of the rail seats are desirable in combination with properties that may vary in a wide range, such as low seat size, low weight, low manufacturing cost and positioning of the spring strength and installation conditions.

The rail seat according to the invention is explained in more detail according to the accompanying drawings.

The track rail seat 2 according to the invention is a rail seat 2 in one piece. It consists of a metal flame 4 and a similar top plate 6, which are connected to each other by a vulcanized rubber outline (elastomer) 8 (FIG. 6).

The shape of the upper plate 6 of the rail seat 2 is symmetrical (not axisymmetric) (FIG. 1), and the axis 12 of the upper plate 6 is, for example, α = 57. If it is rotated by (30 ° <α <90 °), it is rotationally symmetric with respect to axis 12.

The top plate is provided with a rail channel 40. This rail is attached to the upper plate 6 of the rail seat by clamps 18 at diagonally symmetrical points 14. By means of the variable design of the top plate 6, other types of clamps 18 may be used. Using a corresponding insert (spacer block), the rail seat 2 is adapted to accommodate the rail 16 having a base width of 150 mm.

At a point in the rail channel 40 where the rail is not guided through the receiving means for the clamp 18, the rail 16 is guided by a web (protection against warping), the length on the top plate 6. Extends from side to side. In this way, the rails 16 are prevented from twisting out of the longitudinal axis of the seat.

The surface of the upper plate 6 on which the rail is to be placed is slightly raised in relation to the upper edge of the flame 4, thus making it possible for the upper plate 6 to protrude when the rail 16 is placed thereon.

The top plate 6 is closed and has a rounded frame 4 as a whole.

The flame 4 is located with a so-called lift prevention 22 which prevents the top plate 6 from tilting or rising.

A bore containing a device for attaching a sheet on the bottom surface (for example, a screw bolt, a rail screw with plastic dowels, a rail anchor) is located next to the rail fastening 18 to save space. It also allows for the widest possible range of applications, for example wood sleepers and concrete sleepers.

This attachment to the bottom surface is in such a way as to enable lateral adjustment of the rail seat 2 using the toothed disk 26 and the corresponding symmetrical toothed wheel device 28 on the flame 4 (FIGS. 4A and 4B). Can be performed.

The flame 4 rests completely on the lower surface and turns all the horizontal loads generated by the static frictional force to the lower surface. As such, the fastening elements (eg rail screws) of the rail seat 2 do not receive any lateral force.

The rubber contour 8 (FIGS. 5, 6, 7) is equipped with a number of deformable bodies and rubber handles 30 that differ in shape, size and arrangement. This particular design of the rubber contour 8 is arranged under the upper plate 6, but ensures evenly and reliably the spring action of all the loads that occur.

Two orthogonally symmetrical quadrants 34 and 38 each have a larger surface while two other quadrants 32 and 36 are smaller. The size and number of knobs associated with the quadrants are arranged in such a way that the overall strength of each quadrant is equal. Accordingly, it is not fully understood that the upper plate of the rail seat can be inclined due to the symmetry conditioned by its structure.

The stability of the rail seat is improved by the arrangement of the handles. In particular, the rail seat 2 and the rail 16 are thus protected from harmful stresses and the accuracy of the track's line is maintained.

The height of the rubber handle is preferably h _handle = 12 mm and the thickness of the rubber layer disposed on the same is preferably (constantly in each case) h _layer = 9 mm. However, these values can be changed within a narrow range.

Although the rubber contour 8 is changed, the rail seat 2 can be applied to each current stress. This may be further influenced by the individually adjustable properties of the elastic body 8 used.

The track rail seat of the present invention provides a structure composed of as small a sheet as possible.
