Definitions

  • the invention relates to a switch with a trunk track and a branch track, wherein in each case a rail of each track is formed as a tongue rail and movable in contact with the respective stock rail.
  • tongue rails made of special, wear-resistant materials or to harden by subsequent treatment have a number of disadvantages, for example, head-hardened tongue rails for safety reasons are generally not used because any signs of wear should be visible on the tongue rail, so that a risk of breakage can be detected early.
  • head-hardened tongue splints a fracture occurs, but mostly as a brittle fracture, so that early detection is not possible.
  • tongue rails which are reinforced in thickness to absorb shear forces safely can.
  • Tongue rails have become known, the tongue ends in Direction to the stock rails have reinforcements, which correspond to recesses on the running edge of the stock rail.
  • the tongue rail engages in the voltage applied to the stock rail state in the recesses of the stock rail, so that there is a continuous edge in the transition region of stock rail to tongue.
  • DE-OS 2,046,391 due to the recesses formed in the stock rail, there is a significant weakening of the stock rail and, therefore, in the outward state of the tongue, the recesses of the stock rails must be filled with adjusting wedges.
  • the task The present invention is therefore to provide a tongue rail with increased wear resistance and prolonged service life by reinforcing the tongue in the front area such that the security is increased by reducing the risk of breakage, while the original driving course should be influenced as little as possible to the comfort to increase when driving on the switch.
  • the invention consists essentially in carrying out a switch according to claim 1.
  • the largest reinforcement of the tongue rail thus takes place in the sensitive transition region of the load of the stock rail on the tongue rail and it is characterized a cross-sectional increase and thus an increase in the Moment of inertia of the tongue rail achieved so that the tongue rail can better withstand the increased lateral forces.
  • the driving edge course of the stock rail is only slightly changed, so that no adverse effects on driving behavior can be observed when the tongue is lying down.
  • the preferably continuous change in cross section avoids a jerky change in the lane, so that the driving comfort is not adversely affected and a shock loading of the rails is avoided.
  • the running edge of the rail results at the rail head at the widest point, which is measured in a predefined or by standard fixed vertical distance from the driving edge.
  • the training such that the stock rail is chamfered in the area of the system to the tongue rail, the chamfer of the driving edge starting inclined rail track runs.
  • the rounded trained area at the transition between the driving edge and the driving edge naturally results from the intersection of chamfering with the cheek rail head profile edge, with which the wheel flange of the impeller comes into contact.
  • this is formed from the intersection of the fumigation with the cheek rail head profile resulting edge rounded, which further advantageously formed the rounding so is that the baking rail head profile is formed at the transition of the driving edge for chamfering with a curvature whose radius is smaller than that of the corresponding curved portion of a rule rail profile. This creates an overhang in this area, so that despite reducing the width of the baking rail head results in a very small change in track.
  • the contact geometry between the wheel track in the region of the transition of the impeller from the stock rail to the tongue rail is optimized by such a design, so that a particularly smooth transition is achieved in this area.
  • a particularly resilient and wear-resistant switch results when the largest reinforcement of the tongue rail is, as already mentioned, formed in that region in which the impeller comes laterally into contact with the tongue rail and therefore the switch according to the invention is developed in such a way according to a preferred embodiment, that the point with the greatest reinforcement of the tongue rail or with the smallest width of the cheek rail head at a distance of 1/5 to 1/3, preferably 1/4, the length of the system of the tongue rails to the stock rail from the tongue tip.
  • the greatest deviation of the driving edge course from the normal course can be observed and it is therefore to choose the extent of the reinforcement of the tongue rail or the reduction of the width of the stock rail such that there is an increased wear resistance with the least possible change in the running edge.
  • a particularly advantageous embodiment results here when the maximum width reduction of the stock rail or the maximum reinforcement of the tongue rail is 2 to 5 mm, preferably 3 mm.
  • the switch according to the invention is advantageously developed in such a way that the vertical height of the tongue rail in the area of the abutment against the stock rail increases from the tongue tip towards the end of the plant.
  • the contact geometry in this area can be further improved if, as it corresponds to a preferred embodiment, the inner edge of the wheel lane, which preferably with the impeller axis an angle of 50 ° to 70 °, in particular 60 °, at least in the region of the greatest reinforcement of the tongue rail runs parallel to a tangent to the tongue rail and the stock rail or touches the rails along this tangent.
  • the impeller touches both the tongue rail and the stock rail, wherein an upgrade of the impeller is prevented.
  • the reinforcement according to the invention of the tongue rail cross section and the associated increase in the wear resistance is advantageous, in particular in switch geometries, in which high transverse forces occur.
  • the switch according to the invention is therefore an internal curved turnout, wherein the curve outer tongue rail is formed reinforced in cross section.
  • Fig.1 is the back rail of the trunk track with 1 and the tongue rail of the branch track 2, wherein only that area is shown in which the tongue rail 2 rests against the stock rail 1.
  • the running edge is formed, wherein in Fig. 1 It can be seen that the running edge is not rectilinear, but that the width of the stock rail 1, starting from the region of the tongue tip 3 of the tongue rail 2 to the region 4 formed decreasing and in turn is increasingly formed in the adjoining area, so that a bent course of the running edge 5 results.
  • the tongue rail 2 is formed reinforced according to the reduction of the width of the stock rail 1 in the direction of the stock rail 1, wherein in the area 4, in which the impeller laterally comes into contact with the tongue rail, the largest reinforcement is provided.
  • FIG 5 Now is the cross section of the cheek rail head at the point 4, at which the width of the stock rail 1 is most reduced, shown.
  • the dashed line 6 the standard profile of the stock rail 1 is indicated, as it outside the area of the system of the tongue rail 2 is formed.
  • the running edge of the indicated by the dashed line 6 standard profile in this case runs at the point marked 7, wherein 8 a chamfer or an undercut is indicated, as he inclined according to the known embodiments or according to the prior art, starting from the running edge 7 extending below, is designed to facilitate the installation of the tongue rail 2.
  • the undercut is progressively formed up to the point 4, so that at the point 4, which in FIG Figure 5 with full line illustrated baking rail head profile results.
  • the width of the stock rail 1 has been reduced by the distance a, whereby naturally the tongue rail 2 is reinforced by the same amount.
  • the curved region lying at the transition region from the chamfering to the standard profile can be designed with a radius r1 which is smaller than the radius r2, which corresponds to the curvature of the standard profile. This results in a displacement of the running edge by a distance of only b, which distance is smaller than the distance a, by which the width of the bach rail is reduced.
  • a wear-resistant switch with increased service life is created with the invention, whereby an increase in safety by reducing the risk of breakage is achieved.
  • the contact geometry is optimized in such a way that the course of the running edge is influenced as little as possible.
