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 apply them to 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 frog tip have a straight line from the tip or after the break point in the area where they can be put together.
  • the centerpiece tip is quite narrow. This results in increased wear.
  • the frog tip does not lie against 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.
  • the object of the present invention is to develop a centerpiece tip of the type mentioned at the outset which is adjustable relative to wing rails in such a way that the driving comfort when driving through the centerpiece 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 frog tip and the wing rail are at least partially curved in the area which can be placed against one another.
  • 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 depending on the passage of the frog tip is also the driving edge, 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 kink point of the wing rail. In this way, the centerpiece tip is protected without influencing the driving behavior of the wheel passing through the centerpiece.
  • the centerpiece tip area can also become thicker, since according to the invention an increase in the distance to the driving edge can be achieved in this area due to the convex shape of the driving edges on both sides.
  • a particularly advantageous development of the teaching according to the invention is obtained when 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) insertable.
  • the frog tip (16) can be designed to be articulated or spring-movable.
  • a corresponding construction can also be seen 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 fitting 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 placed against one another, that is to say with respect to the wing rail (36) between the arrows (44) and (46).
  • This area is provided with the reference symbol (52). Consequently, the contact surface (48) of the frog tip (42) is curved accordingly. In this area, the contact surfaces (52) and (48) of 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 has 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 higher stability and less wear.
  • the tip (58) is actually withdrawn from the frog tip (42), that is to say it 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 turnout 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, starting from the arrow (46), the wing rail (34) or (36) continues tangentially, thus follows the tangent located at the end contact point (arrow 46).
