Definitions

  • the invention relates to a centerpiece for switches or crossings with two wing rails and a centerpiece tip arranged between them, which, with the wing rails, forms track grooves that run at an acute angle to one another for guiding a wheel flange, a transfer area in which the centerpiece tip is relative to the wing rails and Movable perpendicular to the running surface can be achieved in that the running surface of the wheel is supported both on the running surface of the frog tip and on one of the wing rails at the same time.
  • the object of the present invention is essentially to avoid the wear of the frog tip in the transition area from the wing rail to the frog tip by avoiding abrupt transitions, the transition being to be self-regulated as a function of the acting force in such a way that the elasticity of the frog tip is not leads to undesired and uncontrolled loads on the wheel traveling on the heart. Controlled training of the transition report should also be made possible with structurally simple means.
  • the object is essentially achieved in that the transfer area is controlled in a controlled manner in that in the area of a driving edge distance Y of the frog tip with 20 mm ⁇ Y ⁇ 30 mm, both the frog tip and the wing rail form the driving surface of the wheel.
  • the area in which the wheel passes from the wing rail to the frog tip is thus expanded in a controlled manner, so that neither a quasi punctiform or very narrow range of sudden power transmission from the wing rail to the frog tip still uncontrolled power transmissions from the frog tip into the wheel.
  • the relative movement between the centerpiece tip and wing rails can be made possible in that the wing rails and / or the centerpiece tip are arranged on an elastic base.
  • the elasticity of the base can be designed differently in the areas of the individual switch parts in order to achieve a controlled evasion and in this way a targeted force distribution.
  • the teaching according to the invention has the further advantage that the relative movement allows the wing rails and the frog tip to adapt over a longer area to the geometry of the wheel, which in particular protects the frog tip.
  • the elasticity more precisely the relative displaceability between the frog tip and wing rail, can increase towards the free end of the frog tip, so only slightly To absorb forces in the "weak” area of the frog tip and high forces in the areas of the frog tip in which the rail cross-section increases, since the frog tip can "dodge" downwards in its front area.
  • the frog tip is connected to the wing rails via chucks, which in turn, however, enables the rail parts to move with respect to one another.
  • the feed pieces can connect the centerpiece tip with the wing rails with play, the feed pieces themselves being made of metal.
  • the lining pieces can consist of vibrating metal, i.e. vulcanized rubber pieces, which allow the required elasticity, are arranged between two steel plates, the connection between the wing rails and the frog tip being made via bolts which are guided with play at least through the frog tip.
  • the centerpiece tip is elastically displaceable parallel to the tread.
  • the centerpiece tip is designed as a cantilever arm in such a way that the centerpiece tip acts as a bending rod which is clamped in such a way that the centerpiece tip experiences a deflection of 1 mm at a travel edge distance Y2 with 25 mm ⁇ Y2 ⁇ 30 mm with maximum transverse forces normally occurring during operation.
  • the horizontal displaceability with the constraints specified in relation to the driving edge distance represents a self-inventive idea that enables the centerpiece tip - viewed from its free end - to take over the lateral guidance of a wheel at an early age, so that the track groove is chosen to be as small as possible can, that is, the wheel link required for the lane can be bent away relatively early from the travel rail to the wing rail.
  • the elasticity in the horizontal direction of the frog tip must be designed so that it decreases from the free end of the frog tip, that is, the guiding function increases from the top. This has the advantage that the track groove can be selected to be very narrow, without having to pay particular attention to fluctuations in the lead circle spacing or the flange thickness.
  • the free end of the frog tip which is preferably designed as a pin
  • a bush which in turn is held by a chuck clamped between the wing rails.
  • the sleeve which is designed in the form of a hollow cylinder or pot, should have directional damping and / or support and / or spring properties.
  • Suitable material is, for example, Teflon or vibrating metal, whereby the properties required are ensured in the case of a hollow cylindrical shape, for example by a wave structure.
  • a corresponding receptacle is required so that the centerpiece tip can be displaced in a preferred direction relative to the wing rails, the restoring forces being dampable in such a way that undesired force inputs into the wheels passing through the transition area are avoided.
  • the preferred direction for the damping, support and spring properties can be achieved, for example, in that the structure of the sleeve causes damping only in a certain direction, whereas in other areas the sleeve serves as a rigid bearing, that is to say as a fixed receptacle.
  • Fig. 1 is shown in a purely schematic representation and in plan view a frog (10) of a switch or an intersection, which essentially consists of a frog tip (12) arranged between two wing rails (14) and (16), which differs from it front free end (18) extended towards their ends.
  • the centerpiece tip (12) forms, with the wing rails (14) and (16), two track grooves (20) and (22) running at an acute angle to one another for receiving one Wheel flange (24) of a wheel (26).
  • the wing rails (14) and (16) are the rail strands which continue from tongues (not shown) and which are bent in the frog area. The strands continuing from the switch ends merge into the centerpiece tip (12).
  • section B-B (FIG. 3) there is a transfer of force both via the wing rail (14) and via the frog tip (12). Strictly speaking, this transition area is not punctiform, but is slightly flat, since the running surfaces of the wing rail (14) or frog tip (12) are deformed by surface pressure. This is indicated in FIG. 5 by the hatched areas (30) and (32), which are located both in the tread (28) of the wheel (26) and in the running surfaces (34) and (36) of the wing rail (14 ) or the centerpiece tip (12).
  • the tread (28) has detached from the wing rail (14) and force is transferred exclusively via the running surface (36) of the frog tip (12).
  • the transfer area from the wing rail to the frog tip be controlled in a controlled manner, that is to say stretched, so that an area is formed in which force is transferred both to the wing rail and to the frog tip.
  • This is illustrated purely schematically on the basis of FIGS. 6 to 8.
  • Fig. 6 is also a plan view of a heart (38), for example a switch.
  • the basic structure of the frog (38) corresponds to that of FIG. 1, ie a frog tip (40) is laterally surrounded by wing rails (42) and (44), between which track grooves (46) and (48) are formed. Due to the profile of the wing rails (42) and (44) and the frog tip (40) and their bearings or fastenings to be explained in more detail below, however, the transfer area from the wing rails (42), (44) to the frog tip (40) is pronounced in a controlled manner, namely, it extends between the sectional views AA and CC and is generally provided with the reference symbol (50).
  • the running surface (28) of the wheel (26) lies both on the running surface (52) of the wing rail (42) and on the running surface (54) of the frog tip (40), this lying on not so understand that the force is distributed evenly on the frog tip (40) and wing rail (42). Rather, the force is preferably distributed according to the cross section of the frog tip (40), ie, in the area of the section AA, the force absorption from the frog tip (40) is low, whereas in the area of the section CC there is a maximum introduction of force.
  • the area in which both the wing rail (42) and the frog tip (40) together forms the effective driving surface of the wheel extends at a driving edge distance Y of the frog tip (40) preferably with 20 mm ⁇ Y ⁇ 40 mm.
  • the transfer area (50) and the force transmission increasing from the front free end of the frog tip (40) to the widening end is achieved in that a relative movement in the vertical direction between the frog tip (40) and the attached wing rails (42) and (44) is possible so that the level of the driving surfaces (52) and (54) adjusts itself to the acting vertical force.
  • 9 and 10 in which elements corresponding to FIGS. 6 to 8 are provided with the same reference numerals, it is proposed that the frog tip (40) and the wing rails (42) and (44) are forcibly coupled, e.g. are arranged by hydraulic or pneumatic means (Fig. 9) or on elastically designed supports (Fig. 10), which enable the switch parts to move relative to each other when viewed in the vertical direction.
  • hydraulic units (62), (64) and (66) can be arranged in a ribbed plate (60) and actuated in such a way that the feet (68), (70) and (72) connected to them Wing rails (42) and (44) and the frog tip (40), depending on the force acting in the vertical direction, raise and / or lower the switch parts, so as to achieve a height adjustment of the running surfaces, which ensures that over the in Fig 6, the transfer area provided with the reference number (50), force is applied both to the frog tip (40) and to the wing rail (42) or (44) being driven on.
  • FIG. 10 Another construction can be seen in FIG. 10, in which the feet (68), (70) and (72) are arranged on elastic supports (56), (58) and (59) which automatically lower or raise the wing rail (42) or (44) to the frog tip (40) and vice versa.
  • This also achieves the object according to the invention of providing a pronounced transfer area between the wing rail and the frog tip so that it is not unnecessarily exposed to high wear or damage.
  • FIGS. 9 and 10 are also intended to clarify, the wing rails (42) and (44) with the frog tip (40) are supported against one another via lining pieces (74) and (76) known per se and by means of a bolt (80). , which passes through these and the webs of the wing rails (42) and (44) and the frog tip (40). If the chuck piece (74) and (76) is rigid, play is provided in relation to the walls of the tab chambers and in relation to the bores penetrated by the bolt (80) in order to ensure the relative displaceability in the vertical direction.
  • the wheel link assigned to the running edge of the frog point (40) and running parallel to the running rail can be guided away from the running rail, so that the track groove (46) or (48) between the wing rail (42) or . (44) and frog tip (40) can be chosen to be relatively narrow regardless of fluctuations in the guide surface distance or the flange thickness.
  • 11 to 15 show preferred embodiments of a frog (38) designed according to the invention, in which there is the possibility of moving a frog tip (82) both vertically and horizontally to the associated wing rails (84) and (86) in order to on the one hand to form the transition region (50) explained in FIG. 6 and on the other hand to let the centerpiece tip (82) take over the guiding function for a guided wheel relatively early in order to be able to form the track grooves (88) and (90) relatively narrowly.
  • the running surface (92) of the frog tip (82) lies in the region of its free end below the running surface (94) of the wing rail (86) or (84).
  • an elastic connection takes place in the region of the front free end of the frog tip (82) is indicated both in the area of the free end of the frog tip and at a distance from it by the hatched areas (provided in the rear area with the reference numerals (96) and (98)).
  • this can be moved both vertically and horizontally relative to the wing rails (84) and (86) by the level of the driving surface (94) or (104) Wing rail (84) or (86) to match that of the driving surface (92) of the frog tip (82), and on the other hand the frog tip (82) in the flank area (106) or (108) of the driving surface (92) as a guide surface for the Form the flange of a wheel, not shown.
  • the guide surface begins relatively weakly at the free end of the frog tip (82) in order to become increasingly stronger towards the diverging end, so that the assigned wheel control arm no longer has to take over the management task.
  • the relative mobility of the switch parts to one another is made possible on the one hand by the liner pieces (110) and (112) made of vibrating metal in FIG. 13 or by the rigid liner piece (114) according to FIG. 15, but this to the tab chambers (116) of the frog tip (120) has a game.
  • the lining pieces (110) and (112) consist of preferably vulcanized-in rubber pieces (130) or (132) of angular cross section arranged between steel plates (122) or (124) and (126) or (128).
  • the connecting elements such as bolts, which pass through the lining pieces (110) and (112) and the webs of the wing rails (84) and (86) and the frog tip (82) are guided in bores in the area of the frog tip (82), the diameter of which is greater than that of the connecting elements, so as to achieve the required relative displaceability to one another.
  • 16 and 17 show further particularly noteworthy configurations of frog areas in which a relative displaceability between wing rails and frog tip is possible - both vertically and optionally horizontally.
  • the wing rails (150) and (152) shown in FIG. 16 run on both sides of a frog tip (154).
  • the wing rails (150) and (152) and the frog tip (154) are arranged on a common plate (156), but mechanical decoupling takes place through stops (158) and (166).
  • the wing rails (150) and (152) are delimited by stops (162) and (168).
  • the wing rails (150) and (152) In contrast to the prior art, there is no rigid connection between the wing rails (150) and (152) and the frog tip (154) in order to achieve horizontal and / or vertical displacement. However, the wing rails (150) and (152) remain rigidly connected to one another. For this purpose, the wing rails (150) and (152) are penetrated by a screw element, such as bolt (170), which is tightened against the outer plate chambers by means of chucks and spacers, not specified. In the area of the frog tip (154), the screw element (170) is surrounded by a sleeve (180), which in turn is arranged with play in a bore (182) in the frog tip (154).

  • the wing rails (150) and (152) can be arranged on elastic bases (190) and (192) in order to allow the rigid unit to move vertically. Due to the selected construction, a relative displaceability between the frog tip (154) and the wing rails (150) and (152) is possible, in order to be able to absorb forces caused by rail vehicles traveling through the frog area, in particular due to the inherent elasticity of the frog tip (154), that a steady, and not a sudden force can take place.
