Definitions

  • the invention relates to an articulation device for a coupling, in particular for a rail vehicle, with a tie rod and a number of spring elements mounted on the tie rod to dampen the tensile and compressive forces that occur.
  • a plate arranged between them and a support flange that can be fastened to the rail vehicle are arranged, on which this plate supporting the pull rod is held.
  • a linkage device of this kind is in the reference EP 3 385 143 revealed.
  • the coupling head is connected to a steering pin connected to the rail vehicle articulated drawbar, which is provided with spring elements seated on it for damping the compressive and tensile forces arising in the coupled state of the rail vehicle.
  • the rotatable plate is mounted with a steering pin in a sleeve-shaped housing, which is axially displaceable in a flange.
  • An overload safety device in which during normal operation the housing is fixed axially in the flange against one another with overload elements, while in the event of an overload the housing is sheared off and the latter is pushed backwards through the flange together with the rotatable plate and the pull rod with the spring elements will.
  • the object of the invention is to avoid these disadvantages and to provide a linkage device of the type mentioned at the outset which is provided with a simple construction and is easy to assemble.
  • the plate is connected on its outer circumference opposite each other to a support disk in each opening of the support flange by at least two overload elements each arranged next to one another. These overload elements can be sheared off in the event of an overload in the push or pull direction of the pull rod. At least one spring element is very advantageously arranged on both sides of the plate in order to achieve an adapted structure of the device.
  • a secure connection is thus formed between the support flange and the plate, which can be released in a functionally reliable manner in the event of a crash or overload, but which ensures problem-free articulation in normal operation.
  • the pull rod with the spring elements mounted on it and the plate arranged between them can be pushed into the support flange as a modular unit and the plate can be connected to the support disks placed in the openings by means of the overload elements.
  • the plate is manufactured without a pivot and this housing, which is present in the known articulation device, is omitted, which is very advantageous in terms of manufacturing technology.
  • the invention also provides that, preferably in the axis of rotation of the support disks arranged coaxially to one another, a fastening means is provided for their fixation on the plate.
  • the articulation device also provides that the plate and the support disks arranged coaxially to it on both sides are mounted pivotably about a vertical axis in the openings of the support flange.
  • the tie rod is mounted deflectably by a rotary joint in the plate, through which the tie rod can be pivoted both horizontally and vertically.
  • the linkage device shown essentially consists of a connecting rod, a coupling head, a spacer tube, a shell sleeve, an energy absorbing element or similar connecting rod 1 with several spring elements 2 mounted on it to dampen the compressive and tensile forces arising in the coupled state.
  • a support flange 3 that can be fastened to a vehicle body or the like of the rail vehicle (not shown in detail) is provided, which is provided with openings 3' for its fastening.
  • the tie rod 1 is mounted in a plate 5 arranged between these spring elements 2 .
  • Such a linkage device is suitable for rail vehicles of all kinds, such as for passenger cars, freight cars, locomotives or cars for other purposes.
  • the plate 5 is connected on its outer circumference opposite to a supporting disk 10, 11 each in an opening 8', 9' of the support flange 3 by at least two overload elements 14a, 14b arranged next to one another, with these overload elements 14a, 14b having their axes 14 parallel towards each other in a plane of the tie rod 1 and can be sheared off in the push or pull direction of the tie rod in the event of an overload.
  • these overload elements could also be arranged in a manner other than parallel and in one plane.
  • the sectional plane shown along the axes 14 of the overload elements 14a, 14b arranged in pairs is arranged at a distance from the axis of rotation A of the support disks 10, 11 or from the longitudinal axis of the pull rod.
  • This fastener 4a is preferably a screw and serves primarily as an assembly aid. It could also be screwed in at a position other than that shown and several of these could be used per support disk 10, 11. In the event of an overload, this fastening means 4a is also sheared off.
  • the spring elements 2 lined up on both sides of the plate 5 are fitted with five pads in the compression direction and three in the tension direction. Depending on the circumstances, this number can be varied between at least one spring element 2 in front of and behind the plate or, as shown, more than two spring elements 2 .
  • overload elements 14a, 14b are preferably designed as shear bolts or shear bolts. However, they could, for example, also be designed in the form of disks, sliding blocks or some other shape and be provided with groove-shaped predetermined breaking points, and they are dimensioned in such a way that they are sheared off when a predetermined overload occurs.
  • the pull rod 1 is pushed backwards together with the spring elements 2 and the plate 5 in the event of an excessive impact force. Depending on the severity of an impact, this can be overcome without significant damage to the clutch or vehicle. This shows that the number and/or dimensioning of the overload elements used can be varied from case to case, so that their effectiveness is optimally designed under the respective requirements of the maximum impact or tensile forces.
  • the plate 5 has two edge flattenings 6, 7 arranged diametrically relative to one another, which are guided in projections 8, 9 of the support flange 3 which are flattened on the inside almost without play.
  • these flat edge flattenings could also be cylindrical or similar.
  • a cover 12 which closes the opening 8', 9' can be fastened on the projections 8, 9 and can be closed with a number of fastening means 12', e.g. screws.
  • This robust fastening of the cover 12 ensures that the support disks are held securely in the support flange if they shear off and that they can be changed easily.
  • the articulation device provides that the plate 5 and the supporting disks 10, 11 arranged coaxially on both sides are mounted pivotably about a vertical axis A in the openings 8', 9' of the projections 8, 9 of the support flange 3.
  • the pull rod 1 preferably mounted by a pivot 13 in the plate 3 deflectable. From the swivel joint 13 a spherical sleeve can be seen. The pull rod 1 can thus be pivoted both horizontally and vertically by a limited angle.
  • the spring elements 2 with the intermediate plate 5 are installed on the drawbar 1 between a front sleeve 19 and a rear locking washer 15 . They can be fixed and pretensioned against the sleeve 19 by means of a nut 16 or the like that can be screwed into the rear end of the tie rod.
  • the support flange 3 is assigned a centering device, which has at least one centering means 20 on the support flange 3 or preferably on both sides, which consists of a spring pressure element 21 with a sliding element 22 and a guide rail 23 with a guide track 23' that interacts with the latter .
  • This spring pressure element 21 comprises a compression spring 21', a movable piston element 24 which is acted upon by this and on which the sliding element 22, which is preferably provided as a roller, is mounted.
  • This sliding element 22 is pressed by the spring pressure element 21 against the guide rail 23 which is fastened laterally to the plate 5 and runs parallel to the longitudinal axis of the pull rod 1.
  • This guide rail 23 could also be designed directly on the plate and its shape could be cylindrical, curved or of some other shape, depending on the desired characteristics of the centering.
  • This centering with the two centering means 20 on both sides of the plate 5 thus interacts with the unit formed by the tie rod 1 and the plate 5 in such a way that the tie rod 1 is always positioned with its longitudinal axis in the unloaded state in a horizontal alignment approximately in the longitudinal direction of the rail vehicle.
  • these sliding elements 23 act on the guide rail 23 offset relative to the axis of rotation A in relation to the longitudinal axis of the pull rod 1, so that a torque is exerted on the plate.
  • the support flange 3 can have, in a radial extension of the projection 9, a connecting arm articulated on it in a bearing 17, preferably aligned parallel to the tie rod, with a compression spring loading it in the longitudinal direction, which is not shown in detail.
  • Such a link arm is disclosed in European Application No. 19 214 224.8 explained in detail and therefore not described in more detail below.
  • the pull rod 1 In the event of a collision with an obstacle or another vehicle, the pull rod 1 is subjected to overload forces which, when a predetermined strength is reached, cause the overload elements to shear off. As a result, the pull rod 1 together with the spring assembly 2 and the plate 5 can be pushed backwards into a vehicle body of the rail vehicle through this opening in the support flange 3 which is flush with the outer profile of the plate. This means that the spring assembly can be used again after a crash without any great effort, provided that no irreversible damage has occurred.
  • overload elements 14a, 14b which are arranged in pairs with their axes 14 parallel to each other and in the plane in the direction of the pull rod.
  • These four overload elements 14a, 14b are advantageously arranged symmetrically and at the same distance from axis A.
  • the central arrangement of the fastening means 4a, the cover 12 and the number of its fastening means 12' can be seen.
  • the support disks could be fixed in the respective opening of the support flange in the respective opening.
  • the number of overload elements in a respective support disk is at least two. In principle, these could be arranged at the level of the longitudinal axis of the drawbar.
