Definitions

  • the invention relates to a tongue rail for connection to a connecting rail, in particular a tongue device of a switch, with a trailing edge, with an end-side transition region with abutting edge for connection to a corresponding transition region of the connecting rail with corresponding abutting edge, wherein the transition region an outer transition section, a to the outer transition portion adjoining the central transition portion and an adjoining the central transition portion inner transition portion and wherein the abutting edge of the central transition portion is parallel to the trailing edge and the abutting edges of the outer transition portion and the inner transition portion obliquely or an angle to the trailing edge.
  • a tongue device according to the preamble of Anspuchs 1 is known in which an S-shaped butt joint between the tongue rail and the connecting rail is provided.
  • the tongue rail here has a transition region, which consists of three sections, namely, a middle, parallel to the trailing edge extending, elongated transition portion, the ends in each case merges into an outer or inner transition portion, wherein the outer and the inner transition portion are each formed arcuate section.
  • the connecting rail has a corresponding or corresponding transition region.
  • the well-known S-shaped butt joint is thus substantially separated from one another by the central, parallel section, with the ends of the transitional regions each being rounded with a radius of approximately 40 mm.
  • the from the DE 44 10 200 C1 known butt joint provides at the wheel transfer from the connecting rail on the tongue rail or vice versa for a comparatively smooth transition of the load within the butt joint.
  • the parallel middle transition region compensates for differences in expansion of the material combinations of the tongue rail and the connecting rail.
  • Tongue devices according to the type of DE 44 10 200 C1 have compared to tongue devices, in which an oblique joint between the connecting rail and the tongue rail is provided, a significantly increased life.
  • Object of the present invention is therefore to provide a tongue rail or a tongue device with such a tongue rail available, with as little as possible wear occurs and thus long service life of the tongue rail or the tongue device are possible.
  • the length of the outer transition section and / or the inner transition section is more than 30%, preferably more than 50% and in particular between 60% and 80% of the length of the central transition section.
  • the solution according to the invention now provides for an extension of the outer or inner transition section by more than 100% as the lower limit in relation to the solution known from the prior art. It has been found that the significant lengthening of the outer and / or inner transition section results in significantly minimizing impact in a wheel overflow, resulting in significant noise reduction to noiseless passage and at the same time a very reduced susceptibility to wear.
  • the outer and inner transition sections should each have a length of between 65 and 165 mm.
  • the length is between 85 and 135 mm and in particular between 110 and 120 mm.
  • the length of the central transition section should be between 110 and 210 mm, preferably between 130 and 190 mm and in particular between 150 and 170 mm.
  • the length of the outer and inner Transitional section each at 115 mm, while the length of the central transition section is 162 mm.
  • the aforesaid angle is between 10 degrees and 20 degrees, and more preferably in the range of 15 degrees +/- 2 degrees.
  • edge region In connection with the angularly extending edge region, it has been found that it is particularly preferred if this edge region extends in a straight line. However, a straight course of the edge area does not necessarily have to be provided. An arcuate configuration of the oblique edge region is possible if a correspondingly large radius is selected. Preferably, radii of greater than 1000 mm.
  • the radius of this arc region should be between 100 mm and 500 mm, preferably between 200 mm and 400 mm and in particular between 250 mm and 350 mm. In a particularly preferred embodiment, the radius of the arc region is 300 mm +/- 10 mm.
  • the arc length of the arc area should be at least 10 mm.
  • the angled edge region preferably merges into a further curved region, which then crosses the trailing edge.
  • the radius of the wider arc area should be between 20 mm and 80 mm.
  • the radius of the further arc region is preferably between 30 mm and 70 mm and in particular between 40 mm and 60 mm. In a particularly preferred embodiment, the radius of the further arc region is 50 mm +/- 5 mm.
  • the arc length of the further arc region is at least 5 mm.
  • an arc region adjoins the angularly extending edge region of the outer or inner transition section, wherein the Radius of the arc portion adjacent to the central transition portion is greater than the radius of the other arc portion extending in the direction of the trailing edge.
  • the invention provides that the abutting edges of the inner and the outer transition section are point-symmetrical with respect to the center of the abutting edge of the central transition section.
  • the width of the central transition section corresponds to 40% to 60% of the rail head width.
  • the width of the central transition section is 50% +/- 2% of the rail head width.
  • the abutting edge of the transition region has a chamfer, preferably from 0.5 mm to 4 mm, in particular from 1 mm to 2 mm.
  • a passage opening with internal thread for a threaded screw is provided in the transition region of the tongue rail transversely to the rail longitudinal direction.
  • the threaded screw is screwed in, whose length should be greater than the width of the transition region the tongue rail. Screwing in the threaded screw causes the front end of the threaded screw to act directly or indirectly on the transition region of the connecting rail, so that the transition region of the tongue rail is depressed from the transition region of the connecting rail, which in turn leads to breakage of the corroded connection in the joint region.
  • the passage opening with thread on the shock side passes into a recess for a form-fitting body, wherein the recess opposite the passage opening has an enlarged diameter.
  • a corresponding recess for the positive-locking body is then provided, wherein the positive-fit body is inserted at least substantially accurately in the two recesses.
  • the form-fitting body ensures a positive connection between the connecting rail and the tongue rail in the mounted state and ensures that any shear forces occurring in the region of the tongue rail are not transferred to the screw connections between the tongue rail and the connecting rail.
  • the form-fitting body is ultimately in the form of a short cylinder or disc without a central opening, for pressing the tongue rail of the connecting rail, the threaded screw then directly on the positive-locking body and thus only indirectly acting on the connecting rail.
  • the threaded screw does not necessarily have to be longer than the width of the transition region of the tongue rail.
  • the present invention relates to a tongue device with a stock rail, a connecting rail and a tongue rail of the aforementioned type.
  • the connecting rail on a transition region of the tongue rail corresponding transition region. Since the abutting edges of the two transition regions lie directly opposite one another, the abutting edge course and also the transition sections of the tongue rail described above correspond to those of the connecting rail.
  • the above statements on the abutting edge course and the formation of the individual transition sections of the tongue rail thus apply in the same way to the abutting edge of the connecting rail and the related transition sections of the connecting rail. The foregoing is therefore incorporated by reference for avoidance of repetition.
  • a tongue device 1 of a switch which has a stock rail 2, a tongue rail 3 and a connecting rail 4.
  • the stock rail 2 and the connecting rail 4 are mounted on a base plate 5.
  • the tongue rail 3, which has a trailing edge 6, is provided on the end with a transition or connection region 7, which serves for connection to the connection rail 4.
  • the transition region 7 is bordered by an abutting edge 8.
  • a abutting edge surface connects, which ultimately extends at right angles to the underside of the tongue rail 3.
  • a corresponding transition region 9 is provided with a corresponding abutment edge 10 with a corresponding abutting edge surface.
  • the transition regions 7, 9 represent the region of the butt joint between the tongue rail 3 and the connection rail 4.
  • the butt joint with the transition regions 7, 9 is shown in detail in FIG Fig. 12 shown.
  • the transition region 7 has an outer transition section 11, a central transition section 12 and an inner transition section 13.
  • the sections 11, 12 and 13 directly merge into one another, with a rail region 14 adjoining the inner transition section 13, in which the tongue rail 3 has the maximum head width.
  • the abutting edge 8 of the middle transition section 12 runs parallel to the trailing edge 6, while the abutting edge 8 extends obliquely to the trailing edge 6 in the region of the outer transition section 11 and of the inner transition section 13.
  • the length I of the outer transition section 11 and also the length I of the inner transition section 13 are each more than 30%, preferably more than 50% and in particular between 60% and 80% of the length L of the central transition section 12.
  • the aspect ratio I / L is about 0.7.
  • the sum of the lengths I of the outer transition portion 11 and the inner Transition portion 13 is greater than the length L of the central transition section 12.
  • the extending over the individual transition sections 11, 12, 13 abutting edge 8 has at the outer transition portion 11 and also at the inner transition portion 13 each have an edge portion 15 which extends at an angle ⁇ , which is between 5 degrees and 25 degrees to the trailing edge 6. In the present case, the so-called system angle ⁇ is 15 degrees +/- 2 degrees.
  • the length of the edge region 15 is more than 10 mm. Overall, the edge region 15 is rectilinear. It can also run under a radius of greater than 1000 mm.
  • the edge region 15 at the outer transition section 11 and also at the inner transition section 13 transitions over an arc region 16 into the abutting edge 8 of the central transition section 12.
  • the radius of the arc region 16 is 300 mm +/- 20 mm.
  • the arc length of the arc portion 16 is larger than 10 mm.
  • the edge region 15 also passes over in an arc region, namely the further arc region 17.
  • the radius of the arc portion 16 is greater than the radius of the further arc portion 17, which is present at 50 mm +/- 5 mm.
  • the arc length of the further arc portion 17 is at least 5 mm.
  • abutting edge 8 of the transition region 7 with respect to the center of the central transition section 13 is point-symmetrical. This means that the course of the abutting edge 8 in the outer transition section 11 and also in the inner transition section 13 correspond to each other.
  • the width b of the central transition section 11 corresponds to 40% to 60% of the width B of the rail head of the tongue rail 3 or of the rail section 14.
  • the width b is about 50% of the width B.
  • the abutment edge 8 of the transition region 7 has a chamfer at its upper edge, which is preferably 1 mm to 2 mm.
  • a through hole 18 is provided which has a thread 19 as an internal thread.
  • a threaded screw 20 can be screwed.
  • the passage opening 18 merges on the impact side into a recess 21 which is open on the impact side and which is provided for at least partially accommodating a form-fit body 22.
  • the recess 21 has an opposite to the passage opening 18 enlarged diameter.
  • a thread is not provided on the recess 21.
  • the positive-fit body 22 can be inserted into the recess 21 substantially accurately.
  • the positive-fit body 22 has a cylindrical-segment-shaped or disk-like shape whose thickness is greater than the depth of the recess 21.
  • the recess 21 in the transition region 7 of the tongue rail 3 corresponds to a recess 23 in the transition region 9 of the connecting rail 4. From the diameter corresponds to the recess 23 of the recess 21.
  • the screw has two threaded screws 24 through corresponding, thread-free passage openings 25, 26 are guided in the transition or connection areas 7, 9.
  • the tongue rail 3 For mounting the tongue rail 3, this is based on the in Fig. 3 initially placed on the tongue device 1, in such a way that the transition regions 7, 9 abut each other, as in Fig. 2 is shown. It is important to ensure that the positive fit body 22 is located in the recesses 21 and 23. Then, the threaded screws 24 are inserted through the through holes 25, 26 and bolted end. Subsequently or only for disassembly of the tongue rail 3, the threaded screw 20 is screwed into the thread 19 of the through hole 18.
  • the threaded screws 24 are first released. Subsequently, the threaded screw 20 is screwed in until the end of the screw acts on the form-fitting body 22. Upon further screwing the threaded screw 20, the tongue rail 3 is moved away with its transition region 7 from the transition region 9 of the connecting rail 4, so that the tongue rail 3 can then be removed as needed from the tongue device 1.
