Definitions

  • the invention relates to a frog tip that is adjustable relative to wing rails, wherein each wing rail is kinked in the area of the tip of the frog tip and the wing rail can be placed in regions on the frog tip and vice versa.
  • Known switch and crossing constructions have articulated or spring-movable frog tips, by means of which it is possible to place them on the rail tracks which continue from the tongues and which are referred to as wing rails.
  • the driving edges of the crossing rail tracks are interrupted.
  • the kink point of the wing rail and the centerpiece tip are aligned with one another in such a way that their tip basically comes to lie in the kink point or essentially in the kink point.
  • Both the wing rail and the centerpiece tip have a straight line from the tip or after the break point in the area where they can be put together. Depending on the angle enclosed by the rail sections in front of and behind the break point, the centerpiece tip is quite narrow. This results in increased wear.
  • the frog tip does not lie on the wing rail to the required extent, so that a gap is formed which, on the one hand, impairs the driving comfort when passing through the switch or the crossing and, on the other hand, harbors the risk of the frog tip being destroyed.
  • a tongue switch with a pivotable centerpiece is known, which can be connected via oblique joints to associated rail extensions, which in turn consist of rail ends bent outwards and track sections abutting them.
  • the object of the present invention is to develop a frog tip of the type mentioned at the outset which is adjustable relative to wing rails in such a way that the driving comfort when passing through the frog is improved. Also, any spacing between the wing rail and the frog tip should not lead to impairment, in particular not to an increased load on the frog tip.
  • the object is essentially achieved in that the frog tip and the wing rail are curved in the region that can be placed against one another, at least in regions, in a uniform manner.
  • the radius of curvature of the wing rail and frog tip should preferably be the same size in the area that can be placed next to one another, i.e. with respect to the contact surfaces, which is also the driving edge at the frog tip depending on the passage thereof, where appropriate the radii of curvature of each wing rail and thus that which can be applied to it Section of the frog tip can differ from each other.
  • the tip of the frog tip is retracted with respect to the break point of the wing rail. This protects the tip of the frog without affecting the driving behavior of the wheel passing through the frog.
  • the wheel contact point of the wheel passing through the centerpiece is influenced in such a way that the otherwise frequently occurring abrupt transition is reduced.
  • the centerpiece tip area can also become thicker, since, according to the invention, an increase in the travel edge distance can be achieved in this area due to the convex course of the travel edges on both sides.
  • the curved course of the frog tip extends beyond the area in which the frog lies on the wing rail.
  • the wing rail itself outside of the area in which the frog tip lies against the wing rail or vice versa, follows a tangent which is placed through the point of contact with the wing rail which is furthest away from the tip of the frog tip.
  • the heart of switches or crossings is the result of overlapping rail tracks.
  • the edges of the crossing rail tracks are interrupted in the area of the centerpiece.
  • the rail tracks that continue from the tongues are bent in the centerpiece area.
  • the centerpiece tip (16) with its respective sides (22) or (24) is in a region (26) or (28) on the wing rails (12), (14), specifically in the bent region (30) or (32) can be created.
  • the frog tip (16) can be designed to be articulated or spring-movable. A corresponding construction is also evident in the case of movable wing rails, which are therefore displaceable to the centerpiece tip.
  • the frog tip (16) is in its front area, that is very narrow in the area of the tip (17) of the frog tip (16). As a result, the frog tip (16) is subject to increased wear. It can often also be ascertained that a gap is formed between the wing rail (12) or (14) and the normally adjacent frog tip (16), that is to say in the area (26) or (28), so that when the frog (16 ) driving comfort is impaired.
  • a frog area is designed such that its wing rails (34) and (36) no longer run straight, but curved after the break point (38) or (40) .
  • This curved course is predominant at least in the areas in which the frog tip (42) and wing rail (36) or (34) can be put together, that is to say with respect to the wing rail (36) between the arrows (44) and (46).
  • This area is provided with the reference number (52). Consequently, the contact surface (48) of the frog tip (42) is also curved accordingly. In this area, the contact surfaces (52) and (48) of the wing rail (36) and frog tip (42) also have the same radius of curvature when the surfaces lie against one another.
  • the radius of curvature in the area (54) of the wing rail (34) and that of the facing side or surface (50) of the frog tip (42) can correspond to that of the area (52). However, this is not absolutely necessary. Rather, the radii of curvature can also differ from one another.
  • the centerpiece tip (42) in which areas (52 and (54), that is to say the contact surfaces (48) and (50) and thus the driving edges, are curved outwards gives the advantage, inter alia, that the distance between the driving edges in The areas (52) and (54) are enlarged, and consequently the frog tip (42) can be made thicker in its tip area (56), which results in greater stability and less wear.
  • the tip (58) is actually withdrawn from the frog tip (42), that is to say can be offset from the break point (38) or (40) with respect to the switch tongue. This measure also protects the frog tip (42). The distance is smaller with small-bend turnouts than with big ones.
  • the distance between the tip (58) and the break point (38) or (40) can be, for example, 80-100 mm.
  • the curved course of the frog tip (42) is not only given in the areas (48) and (50) adjacent to the wing rails (34) and (36), but extends beyond this area, to the extent shown in FIG. 2 drawn arrow (60). Then the usual course, predetermined by the switch geometry, takes place.
  • the wing rails (34) and (36) should only be curved in the area of their contact surfaces, that is to say in the areas (52) and (54). At the end of the area (52) or (54), that is to say starting from the arrow (46), the wing rail (34) or (36) continues tangentially, that is to say follows the tangent located at the end contact point (arrow 46).
