Definitions

  • the invention relates to a device for supporting a tongue rail of a switch with a biased to the tongue rail, cantilevered leaf spring on which the tongue rail is slidably mounted.
  • Tongue lifting devices as described in DE 198 12 795 Cl, allow the reduction of wear and thus the saving of large amounts of lubricant by the tongue rail is pushed by a spring upwards, and rests only when crossing a train on the sliding chair.
  • the disadvantage proves still considerable force, since the frictional force is largely independent of the surface.
  • bearings are increasingly used. Since the rolling elements can not withstand the very high loads when crossing a rail vehicle, special design measures must be taken. One possibility is, as described in DE 42 24 158 AI, lower the tongue rail on the sliding chairs by depressions in the moving bed at the end positions. Immediately before reaching the end position again a higher force is required.
  • the tongue rail In conventional switches the tongue rail is mounted in several places. It is different in the different camps both the tongue stroke, as well as the distance to the stock rail.
  • the tongue swing is low near the root of the tongue and the distance to the stock rail is large.
  • the tongue stroke is large, and the distance in the adjacent position is zero.
  • Object of the present invention is to expand the function of conventional bearings and to provide a much simpler, and therefore also fast to install and inexpensive device for storage of tongue rails.
  • this object is achieved in that the leaf spring is arranged in its longitudinal direction adjustable in a guide body, which is fastened to the stock rail.
  • the tongue bearing can be significantly simplified.
  • the required actuating force is much lower over the entire stroke due to the lower rolling friction over the entire stroke, as in the conventional storage of switch blades or tongue rails.
  • the restoring forces of the switch are significantly reduced.
  • the carriage can be fixed both positively and frictionally in the guide body, wherein the frictional variant comprises, for example, keyways. This has the advantage of a continuous adjustment.
  • the carriage can be fastened to the guide body via a connection which consists of a surface of greater hardness with a regular or irregular surface structure and a counter surface of lower hardness.
  • the harder surface can be made for example of steel and the counter surface, for example, brass or aluminum.
  • a safety against loosening is achieved by embossing the surface structure of the harder surface when tightening the screw in the softer mating surface.
  • a toothing can be provided both on the carriage, as well as in the guide body, whereby the position of the carriage is permanently fixed in the adjustment, which is preferably secured by screwing. It is thus an adjustment of the projection over the life of the device prevented by, for example, vibration. It is particularly favorable when the toothing is arranged on one side of the guide body or the matching counterpart on one side of the carriage. A secure connection can be achieved if the screw is arranged on the same side as the toothing.
  • the position of the guide body relative to the stock rail can also be changed.
  • a plurality of bores are present both on the clamping body, which represents the connection to the stock rail, and on the guide body, with which clamping body and guide body can be screwed together in different positions. This allows a coarse adjustment, the fine adjustment can be made by moving the carriage in the guide body.
  • clamps are arranged directly on the guide body in order to obtain a simpler system of fewer individual parts.
  • the contact force between tongue rail and sliding chair can be arbitrarily reduced in the applied state.
  • the tongue When the tongue is rolled up, it can be completely removed by the sliding chair, whereby the contact force when sliding over it is completely eliminated.
  • the bias voltage can be adjusted via the height of the rolling element relative to the roller block. For a precise adjustment, therefore, a height adjustment of the rolling element in a roller block, which forms the connection between the rolling element and the leaf spring, may be of particular advantage.
  • the use of screws for adjustment proves to be advantageous.
  • Best possible line contact between the rolling element and the tongue root edge can be achieved when the roller block is attached to the leaf spring via a rotational-freedom dowel that allows slight pivoting of the roller block with rolling elements about a vertical axis.
  • FIG. 1a shows a device according to the invention in a side view in a voltage applied to the stock rail position.
  • FIG. 1b shows the device in an oblique view in a position adjacent to the stock rail
  • FIG. 2a shows the device in a side view in a position away from the stock rail
  • FIG. 2b shows the device in an oblique view in a position away from the stock rail
  • Fig. 3a shows a device according to the invention at another point of
  • 3b shows the device in a oblique view in a voltage applied to the stock rail position.
  • FIG. 4a shows the device in a side view in a position away from the stock rail
  • FIG. 4b shows the device in an oblique position in a position away from the stock rail
  • FIG. 5 shows the carriage with leaf spring in a side view.
  • 10 is a roller block with rolling elements of another device according to the invention with two rolling elements in a side view.
  • a guide body 1 is attached via a clamping body 15 of a device according to the invention by means of clamps 2a, 2b to a stock rail 3.
  • the guide body 1 is formed like a box in a U-shape and firmly connected to terminals 2a, 2b via a clamping body, wherein a rigid terminal 2a and a screw 2b are present.
  • the rigid clamp 2a is disposed on the clamp body 15 with which a screw clamp 2b is screwed.
  • the guide body 1 is screwed to the clamping body 15.
  • a plurality of bores are present both in the clamping body 15, as well as in the guide body 1, to allow attachment in different positions along a longitudinal axis of the guide body 1.
  • a carriage 4 which in turn is displaceable and fastened in the longitudinal direction within the guide body 1.
  • a carriage 4 For this purpose are on a side wall of the guide body 1 long holes 12 for fixing the carriage 4 with a screw 13.
  • a rack 5 for locking the position of the carriage 4 is provided on the inner wall of the guide 1.
  • rack pieces 6 In the rack 5 engaging rack pieces 6 are arranged on the side of the carriage 4.
  • the relative position of the clamping body 15 to the carriage 4 can thus be roughly defined by means of the connection between the clamping body 15 and the guide body 1, a fine adjustment is possible via the connection between the guide body 1 and slide 4.
  • Both the distance between the stock rail 3 and a tongue rail 11, as well as the tongue stroke of the tongue rail 11 is different according to the position of storage within the switch. Near the root of the tongue, the range of movement of the tongue rail 11 is small and the distance to the stock rail 3 is large.
  • FIGS. 3a and b show the tongue rail 11 in one of the stock rail 3 adjacent position.
  • Fig. 4a and b show the tongue rail 11 in a remote from the stock rail 3 position.
  • the distance between the middle of the cheek rail and the tongue root edge (contact with the roller) differs depending on the type of turnout.
  • FIGS. 1a, b A device according to the invention in a region closer to the tip of the tongue is shown in FIGS. 1a, b in the position adjacent the stock rail 3 and FIGS. 2a, b in the position away from the stock rail 3.
  • a leaf spring 8 On the carriage 4, one end of a leaf spring 8 is attached.
  • the side facing away from the stock rail 3, surface of the guide body is held by the carriage 4 at a distance A. This is so dimensioned that the leaf spring 8 does not rest on the guide body 1 even at maximum load. As a result, the effective length of the leaf spring 8, and thus the spring properties, remain constant.
  • Another end of the leaf spring 8 is connected via a roller block 9 and screws 17 with a rolling element 10. On this the foot of the tongue rail 11 is located.
  • connection of the roller block 9 with the leaf spring 8 is effected by a vertical dowel pin 16. This allows a slight rotation about its axis, which aligns even with tolerances of the rolling elements 10 at the correct angle to the contact surface of the tongue rail 11.
  • set screws 17 are also arranged in the roller block, with which the rolling elements 10 is adjustable in height. As a result, the bias of the tongue rail 11 can be adapted to the requirements.
  • the tongue rail 11 When crossing a train, the tongue rail 11 rests on the sliding chair 14, over which the majority of the load is transmitted with the exception of the biasing force.
  • the approximately required rolling element position is initially set via the clamping body 15 - guide body 1 connection. This can be done both at the factory in the form of product variants, consisting of the same parts, or site side at the beginning of assembly.
  • the entire device is clamped to the stock rail 3 via the clamps 2a, 2b.
  • the position of the carriage 4 is fixed with the screw 13, by the rack 5 and the rack pieces 6 is an adjustment, for example by vibration , bent forward.
  • the entire system is biased against the tongue rail 11.
  • Fig. 10 shows an alternative embodiment with two rollers. This can for example be used when the tongue stroke is greater than the width of the foot of the tongue rail plus the Aufrollweges.
