Definitions
- the invention relates to a track section in the form of a centerpiece composed of two rail sections and wing rails spaced apart by lining pieces, at least the centerpiece being penetrated by a sleeve surrounding a connecting element such as bolts.
- the driving edges of the crossing rail tracks are interrupted in the centerpiece.
- the rail strands that continue 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.
- frogs can be found in DD 60 326, DE 548 749, DE 23 18 419, D E 81 05 454 U l or DD 60 326.
- 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 heart consists of unwelded rail sections which are penetrated by the sleeve without play.
- the frog sections are preferably completely penetrated by the sleeve, at least in regions, the lining pieces arranged on its two sides and spacing the associated wing rails.
- a track section with a connection element such as a bolt
- a connection element such as a bolt
- a sleeve consisting of two rail sections and the associated wing piece, which is spaced apart from one another by lining pieces
- unwelded heart piece sections forming the heart piece, on the one hand, and those arranged on both sides, and the associated wing rails spacing pieces of chuck on the other hand interlock positively with each other over profiling extending in the longitudinal direction of the heart.
- the profiling consists of one on top of the other Teeth formed from the surfaces of the centerpiece and lining pieces of teeth.
- 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.
- unshielded 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. However, 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 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 that points to the curvature of a wheel passing through the heart is tuned.
- the respective contact surface between the wheel and the guide surface there can be a constant curvature difference or a constantly changing curvature difference, viewed in a plane perpendicular to the longitudinal direction of the track parts.
- Lining pieces are preferably composed of a cuboid-shaped inner section extending from the centerpiece and preferably completely free of play through the sleeve, a first wedge-shaped section widening in the direction of the wing rails, a trapezoidal section in section, and a second wedge-shaped section below and supporting the wing rail head and likewise in the section trapezoidal section together.
- the first wedge-shaped section on the wing rail head side can have an outer surface that 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. 2 shows a section through a second exemplary embodiment of a frog area
- FIG. 3 shows a further section through the centerpiece according to the second exemplary embodiment according to FIG. 2.
- 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 rail (18) and (20) and the lining pieces (22) and (24) and between the lining pieces (22) and (24) and the track sections (12) and (14) and their connection to one another itself takes place without welding, but without a relative movement between them being possible.
- a connecting element such as bolts (26) passes through the unit described above in order 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 intermediate pieces (30) and (32) on the outer web surfaces of the wing rails (18) and (20) in order to achieve the desired force-locking connection between the wing rails (18), the lining pieces (22) and (24) and the centerpiece (16). Due to the fact that 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 described in more detail. or (20) is adapted so that a relative movement is excluded.
- the lining pieces (22) and (24) each consist of an inner cuboid-shaped inner sections (38) and (40), which are supported on the outer web surfaces of the rail sections (12) and (14), and a subsequent one in the direction of the wing rail heads (42) or (44) extending first wedge-shaped section (46) or (48) and that adapted to the tabs of the wing rails (18) and (20) and in a common plane (35) or (37 ) together the wing rail heads (42) and (44) supporting the second wedge-shaped section (34) and (36).
- 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.
- the facing outer surfaces (56) and (58) of the inner wedge-shaped sections (46) and (48), which are trapezoidal in section, extend in coordination with the guide surfaces (50) and (52).
- 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.
- FIGS. 2 and 3 show a further embodiment of a frog area, in which the frog (60), which is assigned to the wing rails (62) and (64), consists of two rail sections (66) and (68) which are not welded to one another , which are preferably made of solid rails.
- lining pieces (70) and (72) are arranged according to FIG. 1.
- the unit thus formed from wing rails (62) and (64), lining pieces (70) and (72) and heart (60) is interspersed with play by a bolt (74), which is on the outside via intermediate pieces (76) and (78) the outer web surfaces of the wing rails (62) and (64) can be tightened. 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 extending 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.
