Definitions

  • the invention relates to a track section according to the preambles of claims 1 and 3.
  • the driving edges of the intersecting rail tracks are interrupted at the heart.
  • the rail strands continuing from the tongues are bent in the frog area and are referred to as wing rails.
  • the two strands, which continue from the turnout ends, are brought together to the centerpiece tip.
  • the tip can either be composed of standard rails (rail frog), composed of construction rails and partially welded (partial block frog) or made from one piece (block frog). The latter are e.g. B. only rarely used in the Deutsche Bundesbahn.
  • track parts are not welded together, they are held together by connecting elements such as bolts. However, it is disadvantageous that there is a relative movement between the rail parts.
  • the present invention has for its object to develop a core of the type described in such a way that rail parts interconnected without welding can not move relative to each other at least perpendicular to the longitudinal axis of the track section.
  • the object is essentially achieved on the one hand by that the centerpiece consists of unwelded rail sections and that the rail sections and at least in some areas the lining pieces are penetrated by the sleeve without play.
  • the object is achieved in that the frog consists of unwelded frog sections which, on the one hand and the lining pieces arranged on its two sides and spacing the associated wing rails, on the other hand, interlock with one another with profiling running in each case in the longitudinal direction of the frog, the profiling consisting of a through superimposed surfaces of the frog sections or frog sections and the teeth outgoing teeth formed teeth, which rest with their tooth flanks without play.
  • the teachings according to the invention ensure in a simple manner that a relative movement perpendicular to the longitudinal axis cannot occur between the rail parts to be connected without welding being necessary in this connection area, in particular in the frog area penetrated by the connection element. As a result, there are no problems with edge decarburization or cracking or problems due to the presence of foreign materials in the abutting surfaces. The formation of corresponding core areas is also more cost-effective.
  • unwelded means that in the connection area between wing rails and frog, that is to say in the area where these elements are connected via the lining pieces by means of a connection element, the frog sections are not welded to one another.
  • this does not exclude that the tip is welded on the tongue side or the control rails are welded on the switch end.
  • the sleeve When using the sleeve, which is arranged without play and by means of which a relative movement in any direction is excluded, it can be pressed or shrunk in the track parts or lining pieces.
  • a further development of a track section in the form of a frog area the wing rails each having a wing rail head with the frog facing guide surfaces for a wheel passing through the frog area, is characterized in that the respective guiding surface of the wing rails has a curvature which is due to the curvature of the frog passing wheel is matched.
  • the respective contact surface between the wheel and the guide surface there may be a constant curvature difference or a constantly changing curvature difference, viewed in a plane perpendicular to the longitudinal direction of the track parts.
  • the bar-shaped or block-shaped lining pieces known in their form are preferably composed of a cuboid-shaped inner section which extends from the center piece and is penetrated by the sleeve preferably completely free of play, a wedge-shaped section which widens in the direction of the wing rails and a section which is trapezoidal in section and one below the Wing rail head and this supporting second wedge-shaped and also trapezoidal section together.
  • the first wedge-shaped section on the wing rail head side can have an outer surface which continuously merges into the guide surface.
  • the relevant outer surface of the first wedge-shaped section can have a curvature that shows the behavior of the guide surface.
  • FIG. 1 shows a section through a frog area, which consists of a frog (16) consisting of two rail sections (12) and (14) and wing rails (18) and (20) running along this.
  • the rail sections (12) and (14) can be made from solid rails.
  • lining pieces (22) and (24) are provided for spacing from the wing rails (18) and (20) to the centerpiece (16), that is to say to the facing rail sections (12) and (14).
  • connection between the wing rails (18) and (20) and the lining pieces (22) and (24) as well as between the lining pieces (22) and (24) and the track sections (12) and (14) and their connection to one another takes place without welding without, however, a relative movement between these is possible.
  • a connecting element such as bolts (26) passes through the previously described unit to achieve a non-positive or partially positive connection, the lining pieces (22) and (24) partially, the rail sections (12) and (14) of the Heart (16) are completely penetrated by a sleeve (28) without play, within which the bolt (26) extends.
  • the bolt is tightened via spacers (30) and (32) on the outer web surfaces of the wing rails (18) and (20), so as to achieve the desired positive connection between the wing rails (18), the chucks (22) and (24) and the centerpiece (16).
  • the sleeve (28) passes through the track sections (12) and (14) and at least in some areas the lining pieces (22) and (24) without play, a relative movement between these and thus to the wing rails (18) and (20) is excluded .
  • the latter is brought about by the lining pieces (22) and (24), each of which has an outer wedge-shaped section (34) or (36) which is trapezoidal in section, and which thus conforms to the geometry of the lug chamber of the associated wing rails (18), which is not further specified or (20) is adapted so that a relative movement is excluded.
  • the lining pieces (22) and (24) each consist of an inner quadrangular and on the outer web surfaces of the rail sections (12) and (14) supporting inner sections (38) and (40), a subsequent in the direction of the wing rail heads (42) or (44) extending first wedge-shaped section (46) or (48) and the adapted to the tabs of the wing rails (18) and (20) and in a common plane (35) or (37) Wing rail heads (42) and (44) supporting second wedge-shaped section (34) and (36) together.
  • the sleeve (28) runs without play within the cuboid sections (38) and (40).
  • the wing rail heads (42) and (44) have guide surfaces (50) and (52) each with a curvature which is adapted to the wheels (54) passing through the heart.
  • Matching the guide surfaces (50) and (52), the facing outer surfaces (56) and (58) of the inner wedge-shaped, trapezoidal sections (46) and (48) extend.
  • the materials used for the rail sections (12) and (14), the lining pieces (22) and (24) and the sleeve (28) should have the same or almost the same expansion coefficient.
  • a further embodiment of a frog area is shown, in which the frog (60), which is assigned to the wing rails (62) and (64), consists of two non-welded rail sections (66) and (68) , which are preferably made of solid rails.
  • lining pieces (70) and (72) are arranged according to FIG. 1.
  • the unit formed in this way from wing rails (62) and (64), chuck pieces (70) and (72) and centerpiece (60) is interspersed with play by a bolt (74) which is connected to the outside via intermediate pieces (76) and (78) the outer web surfaces of the wing rails (62) and (64) can be tightened in order to bring about the desired adhesion.
  • the rail sections (66) and (68) of the frog (60) can move relative to one another in the direction of the central axis (80), the superimposed surfaces of the rail sections (66) and (68 ) or the surfaces of the lining pieces (70) and (72) which are in contact with them.
  • This profiling is formed by teeth extending from the superimposed surfaces and running in the longitudinal direction of the frog, of which, for example, only one tooth in each surface with the reference numerals (82), (84), (86), (88), (90) and (92) is provided.
  • the respective teeth are designed such that tooth flanks of interlocking teeth are aligned with each other without play, whereas the associated tooth head (81) and tooth base (83) are spaced from one another by teeth emanating from opposite surfaces (see also enlarged detail in FIG. 3).
  • flanks two of which, for example, are provided with the reference numerals (94) and (96), describe an angle ⁇ to the central axis (80), which is preferably between 65 ° and 75 °, in particular 70 °.
  • the common planes of the lining piece (70) or (72) and the wing rail head underside which is provided with the reference symbol (98) or (100), describe an angle ⁇ to the central axis (80), which is also preferably between 65 ° and 75 °, in particular at 70 °.
