Description

[0001] SEAT FOR A TRACK RAIL [0002]

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

An orbital rail sheet composed of resilient rubber constructed to reduce the noise due to the structure or the noise caused by the incidental air or to generate the necessary elasticity of the upper structure of the transportation means connected to the rail is already known from various types of embodiments have. This kind of track rail sheet is made of a composite of elastic rubber and metal, and they do not have any continuous metal connection between the rail and the bottom surface.

This type of track rail sheet typically consists of a top plate and a frame. The parts of these structures are permanently connected to each other by vulcanized rubber contours. This means that this type of track rail sheet is provided as a part. A linear spring characteristic for a wide load range is required. Further, a modified example of the two-stage spring characteristic is known.

In conventional track rail seats (e. G. DE-40 31 540), the fastening means of the rails on the track rail sheet and the fastening means of the track rail seat to the lower surface are typically aligned axially symmetrically with respect to each other . This inevitably leads to a relatively larger structure. This has the disadvantage that, as well as the disadvantage that the orbital rail sheet is relatively heavy and expensive, it must also be used or provided with a sufficiently large surface area for fastening the track rail sheet to the track body.

The track rail sheet described in DE-PS 34 36 054 consists essentially of a top plate, an elastic rubber profile and a base plate, which are described as rib plates. The base plate is constructed in the form of a frame or a trough and has edge strips extending vertically upwardly on each side edge and securing the elastic rubber contours on the sides to form the frame. The fastening points of the rails are symmetrically aligned on the center line of the laterally extending rib plate. There is provided an offset arrangement of the fastening holes for attaching the seat to sleepers and the like, but there is no space saving effect.

Preferably, the present invention provides a structure composed of sheets as small as possible.

According to one aspect of the present invention, there is provided a track rail sheet comprising a top plate and a frame permanently connected to each other through a vulcanized rubber contour, the rail seat having a device for securing the rail seat to the bottom surface Wherein the geometric shape of the rail sheet is asymmetrical in plan view (not axially symmetrical), and the axis of the upper plate passing through the fastening points of the rails is offset from the center line of the rails, Is present such that the sheet is rotationally symmetrical about its axis and the rails can be attached to the top plate of the rail sheet at positions diagonally opposite by the clamp and the clamp and rail fastening points Wherein the bore is located on the side of the rail fastening point so that the rubber contour is shaped, Wherein the deformations are arranged in a quadrant, each quadrant being located below a corresponding bore or fastening point, and wherein the deformations in each quadrant are of a reliable duration and uniformity of load on the rail sheet, Spring force.

In a variant of the track rail sheet of the type consisting of the frame, the top plate and the rubber profile positioned therebetween, the shape of the top plate of the rail seat according to the invention is not axially symmetric but asymmetrical, And the fastening points of the rails are opposed to each other in a cross-wise manner, and the bore holes are placed next to each one of the rail fastening points.

The track rail sheet according to the present invention is not axisymmetric, unlike a conventional rail sheet. The track rail sheet is merely centrally symmetric and, more precisely, a rotational symmetry, for example a structure in which the two halves can be rotated and superimposed in the same direction. In general, the rotational symmetry axis is placed in a state of being rotated by an angle? From the longitudinal axis (rail axis), for example, while being axially symmetric with respect to the longitudinal axis of the track rail sheet.

Since the axes of the halves of the raceway rail sheet connecting the boreholes are arranged so as to be in line with each other, not only the raceway fastening screws but also the rail screws with bores (anchors, screw bolts or plastic nails) ) Are also arranged very close to the rails so that the entire track rail sheet can be made very small. In addition, as these bores are designed as elongated holes, the fastening portion may be laterally adjusted by the corresponding tooth disc. This is to be used as wide as possible (concrete track carriers, wooden sleepers, longitudinal concrete pylons, horizontal sleepers, steel girders). The track rail sheet according to the present invention ensures the fastening to the lower surface where no lateral force is generated.

In addition to the mounting bores for fastening the seat to the lower surface, a screw chamber cam (cam) for securing the rail is also arranged to be deflected on the track rail seat.

In order to reliably prevent warpage of the rail by offset fixation, for example, another protection against warpage is applied on the side facing the clamp on the top plate.

A rail sheet according to the present invention is a general term meaning that it is provided at an appropriate position including a corresponding insert to receive a rail base having a different width.

The edge region of the frame has a 90 ° offset shape. Here, the frame grasp the perimeter of the top plate at the two outer edge portions, which ensures optimal prevention of lift-up.

On its lower side, the rubber contours are equipped with differently configured knobs. In this way, the spring characteristics can be set in an optimal manner depending on the load.

By designing the track rail sheet asymmetrically and by specifying and aligning the deformations at the bottom of the rail sheet, a distribution of the considered considered strength is made below the surface.

Due to the asymmetrical arrangement of the rail sheets and the smaller size of the structure that may be achieved, high tilt resistances are achieved through specific alignment and design of the rubber knob, even though large tilting moments occur in the top plate .

The rail sheet is designed in such a way that other rubber contour modifications (knob contours) may be implemented on the lower surface. Each rubber profile variant depends on the desired (total) sheet strength. Thus, the four zones have almost uniform strength.

In the design of the rail sheet according to the present invention, it is possible to accurately set the rail sheet strength with a useful variable Shore A hardness of the rubber in consideration of the usual hardness tolerance of the rubber.

From different configurations of the base, it is possible to cover the full range of strengths practically appropriate in this rail sheet. For this purpose, three different rubber outlines are used, the rubber outlines differing in the geometry of the cross-sectional area and the cross-sectional surface as well as the arrangement of the knobs below the top plate.

Due to all these characteristics of the track rail sheet, it is possible to achieve a small sheet size, low weight, low manufacturing cost, and a wide range of changes such as spring strength and position adjustment in the installed state.

The track rail sheet according to the present invention will be described in more detail with reference to the accompanying drawings.

The track rail sheet 2 according to the present invention is a track rail sheet 2 made up of so-called integral parts. It consists of a metal frame 4 and an upper plate 6 which are connected to each other by a vulcanized rubber contour (elastomer) 8 (Fig. 6).

The shape of the top plate 6 of the track rail sheet 2 is asymmetrical rather than axially symmetrical (Fig. 1) and the axis 12 of the top plate 6 extends from the longitudinal axis of the rail sheet 2, e.g. (30. < alpha < 90.), That is, the top plate 6 is rotationally symmetric with respect to the axis 12.

The top plate 6 is equipped with a rail channel 40. This rail 16 is attached to the top plate 6 of the rail sheet by a clamp 18 at a diagonally opposed point 14. By deformation design of the top plate 6, other types of clamps 18 may be used.

Using the corresponding insert (spacer block), the track rail sheet 2 is adapted to receive a rail 16 having a base width of up to 150 mm.

At one point in the rail channel 40 where the rail is not guided through the receiving means of the clamping position, the rail 16 is guided by the web 20, which is used as a protection against twisting, In the longitudinal direction. In this way, the rails 16 are prevented from escaping from the longitudinal axis of the track rail sheet.

The surface of the top plate 6 on which the rails rest is slightly raised relative to the top edge of the frame 4 so that when the rails 16 are placed on the top plate 6, It is possible to make it come out.

The top plate 6 is provided with a frame 4, which is entirely closed.

The frame 4 is provided with a so-called rising prevention portion 22 for preventing the top plate 6 from tilting or elevating.

Bores 24, which accommodate devices for attaching track rail seats on the lower surface (e.g., screw bolts, rail screws with plastic nails, rail anchors), are located next to the rail fastening portions 18 to reduce space . It can also be used in as wide a range of applications as possible for timber sleeper and concrete sleepers.

Attachment to the lower surface allows for lateral adjustment of the track rail sheet 2, using the toothed disc 26 and the corresponding counter-toothed wheel device 28 on the frame 4 (Figures 4a and 4b) . ≪ / RTI >

The frame 4 is placed completely on the lower surface, and all the horizontal loads generated are transferred to the lower surface through the static frictional force. As a result, the fastening elements (e.g., rail screws) of the track rail sheet 2 are not subjected to any lateral forces.

The rubber contour 8 (FIGS. 5, 6, 7) can be provided with a number of deformations and rubber knobs 30 of different shapes, sizes and arrangements. This particular design of the rubber contour 8 arranged below the top plate 6 ensures uniform and reliable spring action of all the loads generated.

Two diagonally opposed quadrants 34 and 38 each have a larger surface, while the other two quadrants 32 and 36 have a smaller surface. The size and number of knobs associated with the quadrant are arranged in such a way that the total intensity of each quadrant is the same. Thus, it can not be entirely possible that the top plate of the track rail sheet can be tilted because of the asymmetry conditioned by its construction.

The stability of the rail sheet is improved by the arrangement of the knobs. In particular, the track rail sheet 2 and the rails 16 thereby are protected from harmful stresses and the accuracy of the lines in the track is maintained.

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

Through the deformation of the rubber contour 8, the track rail sheet 2 can be adapted to the respective actual stresses. This may be further influenced by the individually adjustable nature of the elastomer used.

A track rail structure is provided in which the size of the seat is made as small as possible by the rail rail seat according to the present invention. Also, by determining the shape, size and arrangement of the rubber contours so that the overall strength of each of the other quadrants is substantially the same, the surface area under the rail sheet, despite its small size, low weight and low manufacturing cost, And there is a significant reduction in the risk that the linear accuracy of the entire track will be impaired.
