Definitions

  • the invention relates to a sleeper for rails of a superstructure for rail vehicles, in particular to a long sleeper for receiving sections of at least three rails with an intermediate layer, optionally arranged between the rail and the sleeper, which has damping properties, the sleeper consisting of at least two sections connected in this way are that the sections are movable relative to one another while maintaining or essentially maintaining the distance between the rails.
  • the sleepers which can be any, i.e. steel, concrete, wood or otherwise used sleepers, vibrate naturally, which can result in resonances that result in the substructure being changed like a ballast bed , which in turn causes the threshold and thus the rail to be lowered.
  • this lowering does not take place uniformly over the length of the threshold, so that driving conditions that lead to hazards can occur.
  • DE 40 04 452 A1 discloses a method for the stable laying of at least three tracks which are laid at a short distance from one another. Over-long sleepers are used, which alternately hold a different number of rail tracks. According to DE 38 29 659 A1 prestressed concrete sleepers are coupled over their end areas receiving sleeves. According to DE 91 06 438 U1, Y sleepers are used to store rails.
  • a threshold consisting of two sections, which are connected via a plate having spring properties.
  • the plate starts from turned-over rail sections embedded in the sleeper sections.
  • a railroad track grating is known from DE 27 35 797 A1.
  • the thresholds used can consist of interconnected sections.
  • hook connections are provided, among other things, to enable the sections to be displaced vertically.
  • a pivot connection between threshold sections is known from DE-C 482 003.
  • the present invention is inter alia based on the problem of creating track-like conditions wherever, for example, where additional track components such as wheel links or frogs change the stiffness of the rails and / or a change in thresholds, particularly in relation to the depression, to create track-like conditions, i.e. on the one hand there is a constant depression for each of the rails arranged on a clamp and on the other hand it is ensured that track-like conditions prevail regardless of the static and dynamic loads.
  • the latter means that the elastic behavior in the vertical direction is largely unchanged under static and dynamic loads.
  • the invention is also based on the problem, in particular, of designing long sleepers in such a way that the vibrations generated in them do not lead to a change in the position of the sleepers, that is to say a permanent influence on the substructure.
  • the problem is essentially solved according to the invention in that the sections of the threshold are connected by a connection which is elastically supported in a softer manner than the sections in the vertical direction in the horizontal direction.
  • a threshold is divided into subsections with simultaneous decoupling of them in such a way that there is symmetrical behavior, that is to say in the areas in which on threshold sections there are several next to one another running rails are arranged, set track-like conditions.
  • connection comprises a plate, which in turn is connected to connecting elements that extend indirectly or directly from the threshold sections via elastic intermediate layers.
  • the elastic intermediate layers can be elastomers, the characteristics of which are designed in such a way that there is little spring stiffness in the vertical direction, whereas there is high spring stiffness in the horizontal direction.
  • the connecting elements which hold the connecting plate elastically can consist of an upper section which has a cylindrical shape and is circumferentially surrounded by the elastic intermediate layer and a lower section of smaller diameter which is connected to one of the sleeper sections or one of the base plates.
  • the plate securing the connection between the sleeper sections undergoes force introduction in the direction of the sleeper via at least one screw element, wherein an elastic support is present between the top of the plate and the screw element.
  • connection plate Since the connection plate is connected to the base plates via the connection elements, the connection plate / base plates units are secured via these screw elements.
  • each screw element can be surrounded by a sleeve which is preferably eccentrically formed in some areas, by means of which a change in the distance of the threshold sections is made possible.
  • the sleeve itself is surrounded at a distance from the connecting plate, whereas an elastic spacing element can be arranged between the sleeve and the base plates in order to also rule out noise.
  • connection comprises parallel plates, of which a sleeper-side plate connects the sleeper sections and is elastically supported both with respect to the sleeper sections and with sleeper-facing plates, each associated with a sleeper section.
  • a sleeper-side plate connects the sleeper sections and is elastically supported both with respect to the sleeper sections and with sleeper-facing plates, each associated with a sleeper section.
  • these can also be penetrated by screw elements which introduce forces into the plates in the direction of the thresholds.
  • the sleepers can be known embodiments such as wooden sleepers, concrete sleepers, iron sleepers or act similarly.
  • connection of the sleeper sections (12) and (14) is intended to decouple them without any loss of directional stability of tracks which are fastened to the sleeper sections (12) and (14).
  • the decoupling is intended to enable a relative movement in the vertical direction alone, without a noticeable change in distance.
  • what connection should be given in the vertical direction, whereas in the horizontal direction it should preferably be a rigid connection.
  • a connecting plate (16) is provided which extends from the section (12) to the section (14).
  • the connecting plate (16) in turn is based on connecting elements which are provided with the reference numerals (18), (20) and (22) by way of example.
  • the connecting elements (18) and (20) and (22) each start from a base plate (24) which is assigned to the threshold section (12) or (14).
  • FIG. 2 shows that base plate which is assigned to section (12) and has reference number (24). It can be seen that the connecting elements (18) and (20) are connected to the base plate (24) via lugs (26) and (28). The lugs (26) and (28) and thus also the connecting elements (18) and (20) can be screwed or pressed to the base plate (24). There is also the possibility of inserting the lugs (26) and (28) into the base plate (24). In this case, however, the recesses in the base plate (24) should be lined with an elastic layer, or the shoulders (26) and (28) should be surrounded by such to prevent noise.
  • cylindrical sections (30) and (32) of the connecting elements (18) and (20) extend, which each have a circumferential intermediate layer (34) and (36), which can consist of elastomers, with the connecting plate (16) are connected.
  • the elastic intermediate layers can both on the cylindrical portion (30) and (32) and vulcanized to the connecting plate (16).
  • both the base plate (24) and the connecting plate (16) are secured on the sleeper section (12) by means of a screw (38).
  • the shaft (40) of the screw (38) is surrounded by a sleeve (42), which is optionally eccentrically formed, by means of which the base plate (24) and thus also the connecting plate (16) can be adjusted.
  • a spacer element (46) is provided below the screw head (44) and rests on an elastic ring (48), which in turn rests on the upper side (50) of the connecting plate (16). If the screw (38) is now tightened, the base plate (24) and the connecting plate (16) are secured, the connecting plate (14) being spaced apart from the sleeve (42).
  • the spacing between the connecting plate (16) and the base plates (24) takes place via the cylindrical section (30) or (32) of the connecting element (18) or (20), the underside of which rests flat on the base plate (24), such as 2 shows in particular.
  • FIGS. 4 and 5 differs from that of FIGS. 1 to 3 in the type of connection between a connecting plate (50) and associated threshold sections (12) or threshold-facing plates (52), which in turn each one of the threshold sections assigned.
  • the connecting plate (50) is arranged on the threshold side and is elastically supported both with respect to the threshold section (12) and with respect to the plates (52) facing away from the threshold.
  • elastic intermediate layers (54), (56) and (58), (60) are provided, which are arranged in cylindrical cavities (62), (64), (66) and (68), which are located between mutually facing surfaces of the threshold-side plate (50) and the plate facing away from the threshold (52) or between the preferably just formed top (70) of the threshold section (12) and the facing surface in the connecting plate (50) are present.
  • the elastic intermediate layers (54), (56), (58), (60) are based on T-shaped brackets, one of which is provided with the reference number (72).
  • a shoulder (74) of the holder (72) extends in bores (76) of the connecting plate (50).
  • the connecting plate (50) and the plates (52) facing away from the threshold are secured by means of screws (78), the shafts (80) of which are each surrounded by a sleeve (82), which can optionally be eccentric in order to shift the plates (50) longitudinally. and (52). 5 that the connecting plate (50) is supported with respect to the sleeve (82) and thus with respect to the screw (78) via an elastic intermediate layer (84), which may be on the intermediate plate (50) and / or the sleeve (82) can be vulcanized.
  • Fig. 6 represents an alternative to the sectional view of Fig. 3, which ensures that movement of the plates (16), (24) and the sleeve (42) does not lead to noise.
  • the distance between the threshold sections (12) and (14) can be changed not only by means of an eccentrically designed sleeve, but also via the base plates (24) themselves. This is possible if the receptacles for the lugs (26) and (28) of the connecting elements (18) and (20) are introduced into recesses which are offset with respect to the center of the base plate (24) surrounding the screw element (38) . In a corresponding embodiment, the base plate (24) only needs to be rotated by 90 ° around the shaft (40) of the screw (38) in order to enable the distance between the threshold sections (12) and (14) to be changed.
