Definitions

  • the invention relates to a support of the box of a rail vehicle on a bogie, with at least two laterally arranged, vertical and horizontal relative movements absorbing support units, each containing a spring element and at least one spring plate and at least one intermediate layer made of a rubber-elastic material over which the spring plate against supports the adjacent vehicle part - box or bogie - tiltable in the longitudinal direction of the vehicle, the support unit having a smaller horizontal spring constant in the longitudinal direction of the vehicle than in the transverse direction of the vehicle.
  • the different horizontal spring constants of the support units containing the spring elements are determined by support cams which are formed on the spring plates and run in the transverse direction and each allow an elastic inclination of the support unit in the longitudinal direction of the vehicle when the bogie is turned out, an inclination in the transverse direction however prevent (DE-B 1 530 102).
  • the known support requires a relatively complex design of the elastic intermediate layers to be attached on each side of the support cam, each of which extends over half the spring plate.
  • the largest possible angle of inclination of the spring plate is limited to relatively small values, which can lead to strong deflections and correspondingly high stresses on the spring element, which is deformed in an S-shape, when driving on tight curves .
  • the invention has for its object to provide a support that is improved in this respect in particular, which, without impairing the transmission of the vertical and horizontal supporting forces, enables greater inclinations of the spring plate in the longitudinal direction of the vehicle than before and which specifically influences the ratio of the longitudinal and transverse directions effective horizontal spring constants of the support unit allowed.
  • the intermediate layer is formed by at least one rail-like support piece which is preloaded by compressive stresses under the full vertical support force of the loaded spring element and is essentially rectangular in plan view, which has long sides oriented transversely to the longitudinal direction of the vehicle and essentially in Vehicle longitudinal direction oriented narrow sides is arranged.
  • the inventive design of the support allows the use of simple, commercially available support elements made of rubber-like material, which are available in numerous dimensions, e.g. are available in plate or bar form and which - cut to the required size - can be used as supporting pieces without substantial post-processing.
  • Metallic contact between the bogies and the box is avoided by the support pieces according to the invention and sound insulation is thus achieved.
  • a favorable load is achieved on the supporting elements that transmit the full vertical support force of the associated spring element and are therefore under compressive prestress.
  • the bogie is turned out, the spring plates incline, with restoring moments occurring in the support pieces as a result of changes in normal stress.
  • the inclinable spring plates also relieve the spring element considerably of undesirable large transverse deflections in the longitudinal direction of the vehicle and the associated spring stresses.
  • the ratio between the different horizontal spring constants of each of the support units which are effective in the longitudinal and transverse directions is determined by the ratio of the corresponding dimensions of the associated support piece.
  • the advantages of the embodiment according to the invention can be achieved in particular by supporting pieces of rectangular shape which is relatively narrow in plan view.
  • the restoring torque exerted by the support piece and counteracting the inclinations of the spring plate in the vehicle transverse direction can be at least four times greater than the corresponding restoring moment counteracting the inclinations of the spring plate in the vehicle longitudinal direction.
  • the embodiment according to claim 3 is particularly advantageous for supports with more than one support unit per side of the bogie, since it allows a radial adjustment of the support pieces with respect to the axis of rotation of the bogie, and thus ensures a correspondingly favorable stress on the support pieces when turning the bogie.
  • the embodiment according to claim 4 allows the use of a support piece, the length of which can be greater than the diameter of the spring plate determined by the dimensions of the spring element.
  • the embodiment according to claim 5 allows an increase in the permissible pressure load of the support piece without significantly influencing its lateral and inclination stiffness.
  • the embodiment according to claim 6 enables a precise positioning of the support piece and a securing of the spring element against lateral sliding of the spring plate in the event of damage or destruction of the support piece.
  • the rail vehicle e.g. a locomotive, has a box 1 and at least two bogies 2, only one of which is shown.
  • Each bogie 2 contains a bogie frame 3 with longitudinal members 4, on which the box 1 is supported by two pairs of laterally arranged support units 9, each of which contains a spring element 5 formed from a helical spring.
  • the bogie frame 3 is supported by known primary springs 6 on the axles of two wheel sets 7.
  • the wheel sets 7 are coupled in a known manner with drive motors, not shown, attached to the bogie frame 3.
  • the bogie frame 3 is via a device, not shown, for transmitting the tensile and braking forces, e.g. a deep drawing device known, for example, from CH-PS 638 731, rotatably connected to the box 1 about a vertical axis of rotation (vertical axis) Z.
  • the support units 8 also each contain two spring plates 8 arranged at the ends of the spring plates 5 and two rail-like support pieces 10 made of rubber or a corresponding rubber-like material, each between one of the spring plates 8 and the adjacent vehicle part - the box 1 or the rotary actuator 2 - are arranged.
  • the support pieces 10 are arranged with long sides oriented transversely to the vehicle longitudinal direction x and correspondingly narrow sides oriented essentially in the longitudinal direction x. As can be seen in particular from FIG. 2, the support pieces 10 can be set such that their horizontal longitudinal axes 11, which are essentially elongated and run parallel to their long sides, each intersect the vertical axis of rotation Z of the bogie 2.
  • the support pieces 10 can each be attached to their upper and lower support surfaces, e.g. vulcanized or glued, preferably metallic outer stiffening plates 12 and 12a.
  • the support pieces 10, the stiffening plates 12, 12a and the spring plates 8 can each be provided with at least one bore 13 penetrating them vertically, which for receiving one on the adjacent vehicle part, the box 1 or the bogie 2, fortified dome 14 is suitable.
  • the diameter of the bores 13 in the spring plate 8, in the adjoining stiffening plate 12 and in the support piece 10 are larger than the diameter of the dome 14 by a relatively large amount of play, which allows the operational deformations of the support piece 10, while the plate 12a resting on the vehicle part According to this illustration, a diameter which is suitable for centering the support piece 10 and is only slightly larger than the mandrel 14 can have.
  • a corresponding mandrel 14 can also be attached to the spring plate 8 and provided through the bores 13 of the support piece 10 and the stiffening plates 12, 12a into one on the adjacent vehicle part, on the box 1 or on the bogie 2 Protrude hole.
  • the spring elements 5 of the support units 9 can also each be provided with a single support piece 10 and be supported directly at the other end via the spring plate 8 on the relevant vehicle part, in the example shown on the box 1.
  • the support pieces 10 can also each have a height H that divides between two sections 10a and 10b, e.g. vulcanized or glued, inner stiffening plate 15 may be provided.
  • a plurality of corresponding stiffening plates 15 can also be provided.
  • the rail-like support pieces 10 are each by a relatively large dimension, determined by their relatively small width B, essentially around the longitudinal axis 11 and by a dimension that is substantially smaller according to the ratio between the length L and the width B, by a dimension substantially parallel to the width B extending transverse axis 17 deformable.
  • the rail-like support pieces 10 preloaded by the vertical supporting forces of the loaded spring elements 5 therefore permit relatively strong inclinations of the spring plate 8 with respect to the adjacent vehicle part - box 1 or bogie 2 - in the vehicle longitudinal direction x and correspondingly smaller inclinations of the spring plate 8 in the transverse direction y of the vehicle and small entanglements of the stiffening plates 12, 12a about the axis A of the spring element 5.
  • the unscrewing movements of the bogie 2 relative to the box 1 cause the support units 9 both in the longitudinal direction x, wherein the ratio of x effective in the longitudinal direction of the horizontal stiffness C x and in the transverse direction y effective stiffness Cy each support unit 9 and deflected in the transverse direction y influenced by the ratio between the width B and the length L of the associated supporting piece 10 degrees.
  • the support designed according to the invention can cause a relatively large mutual displacement V of the box 1 and the bogie 2 in the longitudinal direction of the bogie x by a relatively strong inclination of the spring element 5 and a correspondingly small mutual displacement U of the ends of the Spring element 5 are added.
  • the conditions are indicated in the correspondingly inclined operating position of the interacting parts, in which the under normal load - e.g. 3 - straight central axis A of the spring element 5 runs in a slightly S-shaped curved line A '.
  • the support pieces 10 connected to the outer stiffening plates 12, 12a can, as can be seen from FIGS. 2 and 4, each be designed with a length L which is greater than the diameter of the associated spring plate 8, so that the for the predetermined ratio of horizontal stiffness C x / Cy decisive dimensioning of the support pieces 10 can be made largely independent of the dimensions of the spring plate 8.
  • Support pieces 10 with one or more inner stiffening plates 15 are particularly advantageous in designs with a relatively large height H, because this prevents the elastic material of the support pieces 10 from being squeezed out sideways and thus increases the pressure resistance of the support pieces 10.
  • Relatively large heights H are preferably provided when large angles of inclination of the spring plates 8 in the vehicle longitudinal direction x are aimed for.
  • the support pieces 10 can also each be provided with only one outer stiffening plate 12 or 12a and can be arranged with the unstiffened side directly on the spring plate 8 or on the adjacent vehicle part - box 1 or bogie 2 . Versions without external stiffening plates are also conceivable.
  • the bores 13 formed in the support pieces 10 can also be designed as blind bores and can each be provided for receiving a securing part which only extends over part of the height H of the support piece 10.
  • each bogie arranged support units 9 the support pieces 10 are set with long sides parallel to the transverse direction y of the vehicle.
  • an embodiment with support units 9 arranged according to the representation according to FIGS. 1 and 2 is conceivable, the support pieces 10 of which are arranged with long sides running parallel to the transverse direction y.
  • the support designed according to the invention is also suitable for bogies without a drive device.
