Definitions
- the invention relates to a rail bearing according to 2.
- a rail bearing is also known (DE-OS 39 37 086), in which a buffer made of elastic material in one Recess of a concrete sleeper is arranged and a Has a thickness of 40 to 55 mm. A face down Edge of the plate supporting the rail intervenes Buffer and side wall in the recess in the concrete a. In addition, the plate is through to the rail directed arms on a support element on which the middle section the plate tension clamp rests and secured in place. This buffer is not non-positively stored. A damping of horizontal Vibration is not intended. The because of the buffer thickness stronger deflection per se under load leads to increased vibration excitation in the Rail bearing.
- the invention has for its object a rail bearing of the type described above with little construction and high accuracy, both one in the vertical direction and one in the horizontal direction has good damping.
- the buffer is on five sides through a bottom surface and four about this vertical and preferably slightly downwardly converging side walls of the recess framed rigid and is on the sixth side due to the rigid plate, which is under the The influence of the plate clamps is already in the idle state biased towards the dynamic load. This results in a non-positive bearing. This makes the deflection more dynamic as a result Free travel occurring load negligible. The damping occurs immediately under load, and also a damping caused by the axle load in the Rail leading and trailing vibrations guaranteed is. The overall travel remains short. By the rigid shape of the skirt also causes - no matter how the lines of force run under load - a lateral deformation of the buffer is excluded is. This leads to an opposing force.
- This construction also results in a preload of the buffer in both vertical and horizontal Direction with the related Advantages.
- a material of greater hardness for the edge part one achieves that a slight one horizontal compression of the edge part is sufficient, to a sufficient preload respectively to achieve sufficient damping in operation.
- the lateral deflections are very small, so that there is a correspondingly high track accuracy.
- the base part can be essential be softer and therefore stronger under load deflect like this for adjustment reasons the rail that bends under load is desirable is.
- the plate tension clamps not only provide a preload the base part of the buffer in the vertical direction, but in connection with the sloping side walls also for maintaining a preload the edge parts of the buffer in the horizontal direction.
- the plate clamps have a vertical deflection of 1 mm or more and this is one of the inclination angle the horizontal increase depending on the side wall Prestressing the edge part of the buffer results.
- a slight deviation in the side walls is sufficient the recess from the vertical direction, for example an angle of less than 5 °.
- the plate Under pressure, so if there is an even greater deflection, the plate is self-centered, so that there is a correspondingly high track accuracy.
- stronger horizontal counter forces which counteracts stiffening of the base part.
- the distribution of the cavities according to claim 6 ensures that the rail head deflection is further reduced is taken into account because of the uneven load distribution becomes.
- the base part advantageously has a Height of at least 25 mm.
- the range from 40 to 50 mm is preferred. Greater heights are possible.
- the height is one for the achievable damping and deflection essential feature. It not only allows different Compensate for the height of neighboring rail bearings, what you normally use washers for used between rail and plate, but leads also to a stronger compression of the edge parts of the buffer due to the deformation of the elastic material. Transitions between different designs, such as ballast track and solid carriageway, free The route and the switch area can be carried out without any problems.
- the base part has a spring stiffness of 8 to 12 kN / mm.
- a Spring stiffness around 10 kN / mm represents an essential parameter for the formation of a highly elastic bearing and thus for a particularly good damping. Should the spring stiffness of the base part due to the edge parts of the occurring forces can be too soft use a material of greater hardness there.
- a very inexpensive support element results from the Training according to claim 11. Since the plate safely in the recess of the substructure is required one the position of the support elements Plate securing guide.
- the Concrete according to claim 13 be made fiber reinforced.
- the support element can also be fiber-reinforced according to claim 14 be executed. This can reduce the cost of materials be reduced even further.
- the asymmetrical shape of the plate according to claim 15 leads to more even removal in the curve area the rail forces through the rigid plate and thus to stabilize the given Rail inclination. This is particularly suitable for high-speed railways.
- the space is outside keep the plate free from clamping and holding elements. This is especially for the switch and Crossing area of interest.
- 1 to 4 and 6 is a Rail 1 with head 2 and foot 3 with the interposition of one elastic layer 4 on a rigid plate 5 held. This is done with the help of rail tension clamps 6 and 7, with one end 8 on the Support foot 3 and the other end 9 on plate 5 and tensioned in the middle by a nut 10 will.
- This nut is on the thread of one Screwed hook screw 11, which into a rib 12 the plate 5 is suspended.
- the bearing surface 5a of the Plate 5 is slightly inclined so that the median plane the rail a small angle to the vertical forms what the transfer of shear forces to the Plate 5 and the matching of the shapes of rail and Wheel rim relieved.
- This plate 5 is in a recess 13 of a buffer 14 made of elastic material, preferably vulcanized into it.
- This buffer 14 points below the plate 5 has a base part 15, the predominantly one Shore A hardness from 55 to 65, and one around the plate 5 extending approximately vertically upward Edge part 16, which is made of a material with a Shore A hardness is from 70 to 80 and a width owns, which is significantly less than the height of the Base part 15 and smaller in the exemplary embodiments than half the height and preferably about the same is a quarter.
- the buffer has 15 in the base part Cavities 17, which is associated with the lower Shore hardness to a spring stiffness in the vertical direction of leads about 10 kN / mm. On the outside of the curve is the Number of voids reduced. The hereby achieved Increasing the rigidity reduces the lateral deflection of the rail head 2.
- a concrete part 18, in particular a threshold, has a recess 19 in the form of a recess in which the buffer 14 carrying the plate 5 is inserted is.
- the height of the recess is such that the Plate 5 completely or largely within the recess 19 lies.
- the side walls 20 of the recess 19 are slightly less than the vertical Degrees, e.g. 5 °, inclined so that it goes from top to bottom converge. This applies at least to the area of Base part.
- the plate 5 is by two plate clamps 21st and 22 loaded, the biased inner end 23 rests on the plate surface.
- a support member 24 engages with a channel-shaped extension 25 in one Channel 26 and is otherwise 27 by side ribs performed (see. Fig. 4 and 6). The support member 24 is therefore in the longitudinal and transverse directions against displacement secured.
- the second end 28 of the plate clamp 22 engages in the trough-shaped extension 25.
- the middle section 29 is through the head 30 of a screw 31 held on an elevated part 32 of the support member.
- the dashed line 16a in FIG. 2 indicates how the edge part 16 looks in the relaxed state.
- the solid line 16b shows the edge part 16 in the installation position, where the material is under tension stands.
- FIG. 5 shows a modification in which for corresponding Parts used by 100 increased reference numerals will.
- the main difference is that the outer end 128 of the plate clamp 122 immediately rests in the channel 126 of the concrete part 118. Further is the support member 124 between the the side wall 120 formed level and this gutter 126, so it has a very small design.
- the base part 215 consists of five layers a to e, of which layers a, c and e have a greater hardness than layers b and d and where the top layer e is integral with the Edge part 216 is formed. The rest of the parts have remained unchanged have their reference numerals maintained.
- the plate 5 acts with a buffer 314, in which the edge part 316 integral with the top layer of base 315 is trained and has a greater hardness than that lower section of base part 215.
- a buffer 314 in which the edge part 316 integral with the top layer of base 315 is trained and has a greater hardness than that lower section of base part 215.
- steel plates 335 inserted, preferably vulcanized in order the buffer 314 and thus also the rail inclination to give greater stability, which is particularly true for high-speed railways is desired.
- the steel plates can also textile inserts or the like. used will. Due to the multiple media change is nevertheless achieved high damping.
- the multilayer structure is particularly recommended with a cellular structure.
- the recess for receiving the buffer 14 can also be formed by a rectangular frame 36, on a screed or other surface 37 is attached. This can be done in the usual way four threshold screws arranged outside the frame 36 happen or according to FIGS. 12 and 13 by Screws 38 and 39, which the plate 5 "and the buffer 14 prevail, ie completely within the Plate surface.
- the screw 38 has one Head 40, on which there is a helical compression spring trained plate clamp 41 supports. Of the Screw shaft engages in one with its thread the base 37 held nut 42.
- the screw 39 has an abutment 43 on which one is formed Wire bent plate clamp 44 supports.
- the plate 5 is in the embodiments of the Vulcanized buffer material. But it is often enough also, just insert the plate.
