Definitions

  • the invention relates to a device for holding a pulling and pushing device of a coupling, in particular of a rail vehicle, according to the preamble of claim 1.
  • EP 3 792 137 A1 is a box-shaped spacer element to bridge the distance provided, which is connected on the front side to a support element which articulates a pull rod and can be fastened on the back in a vehicle recess of the rail vehicle.
  • This spacer element which can be fixed in the vehicle body of the rail vehicle by means of fasteners, has a stop surface on both sides next to the support element, onto which corresponding jaws in the vehicle body engage.
  • At least one wedge surface is formed on the back of the spacer element, which interacts with adjustable wedges and by means of which the spacer element can be permanently clamped in the vehicle body. It can also be easily dismantled in the event of damage to the facility.
  • a connecting arm preferably aligned parallel to the pull rod, is provided with a compression spring for a supporting compressive force on the pull rod. This means that at least a certain centering height position of the pull rod and thus the coupling can be set.
  • the connecting arm with the compression spring is articulated on the one hand to a hub that projects laterally on the support element and on the other hand to a sleeve body of the tie rod.
  • This device enables a solid and permanent fixation of the holder of the pulling and pushing device in a vehicle body and also enables this central alignment of the pull rod.
  • the invention is based on the object of further developing the same in such a way that it enables a new type of alignment of the pull rod in the coupling or connecting head with stabilization while requiring less space and Furthermore, increased security is achieved in ensuring the functionality of the suspension of the pulling and pushing device.
  • the coupling or connecting head of the tie rod and the housing structure are formed with corresponding sliding guides through which the coupling or connecting head and with it the tie rod are guided longitudinally in the housing structure in the axial direction, a simplified new construction with the directional joint formed is achieved a very stable guidance of the pull rod in the housing structure.
  • dovetail-shaped guideways or sliding guides with the same effect in pairs on both sides of the pull rod. These are preferably within the housing structure, but could also be arranged outside. This stabilizes the alignment of the pull rod and also improves the holding of the pulling and pushing device with regard to torsional loads.
  • the invention provides that the coupling or connecting head and with it the tie rod are guided in the housing structure from a basic position starting in the unloaded operating state to a stop position when pressure is applied. This can ensure that in the coupled state, in the event of a strong pressure surge, the displacement of the coupling or connecting head and thus the tie rod is limited in the housing structure, so that a defect in the device can be prevented in whole or in part.
  • At least one stop surface is preferably arranged in the housing structure and at the front in the coupling or connecting head in such a way that they each form this stop position.
  • the stroke length of the coupling or connecting head from the unloaded basic position to this stop position is advantageously dimensioned such that the spring elements are only compressed within the elastic range and are therefore not damaged in the event of a correspondingly strong pressure surge.
  • this stroke length could also be dimensioned such that the spring elements would be plastically deformed in the stop position and therefore inoperable.
  • At least one indication element is assigned to the coupling or connecting head, which indicates visually and/or by means of an electrical signal or the like when it has been moved from the basic position to the stop position.
  • the entire device and in particular the spring elements must be checked. If this device or parts of it were defective, they would have to be replaced if necessary.
  • This at least one indication element includes, for example, a shear bolt that projects away from the coupling or connecting head and a shear element that breaks it in this stop position the housing structure or vice versa. This allows an operator to determine the actual state of the spring elements and replace them if necessary.
  • the stroke length of the opposite relative movement of the pull rod from the unloaded basic position to the end position of the coupling or connecting head is expediently dimensioned so that its legs are still guided in the housing structure so as not to be detached from it.
  • Fig. 1 to Fig. 3 show a device 10 for holding a pulling and pushing device of a coupling, in particular of a rail vehicle. It is very advantageously suitable for freight wagons in which vehicle recesses are provided on the outside in a vehicle body, in each of which a distance bridging is required, in which such a device 10 can be fastened.
  • the device 10 is provided with a housing structure 15, a support element 16 arranged therein, a pull rod 11 which is displaceably mounted by the latter in the axial direction A and is provided on the front with a coupling or connecting head 20, and on both sides of the support element 16 with several spring elements lined up on the pull rod 11 13 is provided.
  • the pull rod 11 has a final spring element 13 'at the front, which abuts the coupling or connecting head 20.
  • the latter is designed as a connecting head at the front with an articulation consisting of U-shaped support walls 27, 28 and a pivot pin 26 supported by these, to which, for example, a connecting member with a coupling head can be articulated. However, this could be designed directly as a coupling head, which is not shown in more detail.
  • prestressed spring elements 13 serve to dampen the tensile and compressive forces that arise during operation of the rail vehicle, in which, for example, nine can be provided at the front and four at the rear. However, depending on the strength requirements, a different number can be selected. Both these spring elements 13" acting on tensile force and a stop 19 attached to the end of the pull rod 11 with a fastening means 18 as well as the spring elements 13' loaded under pressure are accommodated within the housing structure 15, through which the spring elements 13 are compressed with a defined pressing force Tension or pressure is made possible.
  • This housing structure 15 is expediently box-shaped with a square cross section and, together with the support element 16, it is preferably made in one piece from nodular cast iron or Cast steel made. In principle, it could be designed other than box-shaped and round, oval or similar in cross-section and composed of several parts.
  • the spring elements 13 At the rear end it is provided with an opening 12 'so that the spring elements 13", the fastening means 18 and the stop 19 can be inserted into or removed behind the support element 16.
  • the housing structure 15 there are at least one, preferably several, recesses 12 on all four side walls formed in the housing structure 15, which are dimensioned such that the nut 18 of the stop 19 and the spring elements 13" are accessible for mounting from outside the housing structure 15 or can also be inserted or removed laterally through these recesses 12, especially with these Recesses 12 also achieve weight savings in the housing structure.
  • the coupling or connecting head 20 of the pull rod 11 and the housing structure 15 are designed with corresponding sliding guides 21, 22, through which the coupling or connecting head 20 and with it the pull rod 11 are guided longitudinally in the housing structure 15 in the axial direction A.
  • these sliding guides 21, 22 have a further advantage in that the device 10 can be easily assembled by inserting the coupling or connecting head 20 with the pull rod 11 into the housing structure 15 until the sliding guides 21, 22 are in contact with one another be in contact.
  • the pull rod 11 is guided through the spring elements 13 and the support element 16 and fastened with the stop 19 and the fastening means 18.
  • pairs of dovetail-shaped guideways are designed as sliding guides 21 on both sides of the pull rod 11, which are correspondingly provided in the housing structure 15 starting from the front end 15 'of the same and at legs 23 of the coupling or connecting head 20.
  • two such guide tracks 21 and correspondingly four such legs 23 are arranged in pairs on both sides of the coupling or connecting head 20, so that the latter is held in a form-fitting manner in the housing structure 15 when viewed transversely to the axial direction A and can be moved back and forth in the axial direction A.
  • the coupling or connecting head 20 and the tie rod 11 connected to it are in the housing structure 15 from a basic position P0 starting in the unloaded operating state, as shown in Fig. 2 is illustrated, up to a stop position P1 present at an operational pressure load.
  • the stroke length H1 of the coupling or connecting head 20 from the unloaded basic position P0 to this stop position P1 is dimensioned such that the spring elements 13 'in the stop position P1 are compressed within the elastic range and they or the device are not damaged in whole or in part.
  • the stroke length H1 is preferably selected so that the spring elements 13 'are compressed in this stop position P1 shortly before the maximum possible compression.
  • corresponding stop surfaces 24, 25 ' are arranged on the front side of the legs 23 of the coupling or connecting head 20 and in the housing structure 15, which touch each other in the stop position P1.
  • this stop position P1 could also be dimensioned such that at least some of the spring elements would be plastically deformed or these or possibly parts of the device 10 would be inoperable in the event of an impact.
  • the housing structure 15 is preferably formed in the front half by the recesses 12 with frame-shaped side walls 17 running in the longitudinal direction, which are provided on the inside with the sliding guides 22 and the cams 25 having the stop surfaces 25 '.
  • the support element 16 is arranged approximately in the middle of the housing structure 15. However, depending on the number of spring elements 13 'or the length of the housing structure, it could be placed in the front or rear part of the latter.
  • the coupling or connection head 20 is assigned at least one indication element 30 as a shear bolt with a notch, which is clearly visible below the joint pin 26 and the supporting wall 28. If it breaks, if it has been moved to the stop position and broken off there by a shearing element in a support unit 35 for the housing structure 15, this is displayed visually.
  • the distance between the shear bolt and the stop position is dimensioned to be approximately the same length as the stroke length H1 of the coupling or connecting head 20 up to the stop position P1. In the event of such a break in the shearing element, the entire device must be checked and, if necessary, at least parts of it, along with the shearing element, must be replaced.
  • this indication element could be designed instead of a bolt by electrical signaling, for example when the stop surfaces 24, 25 'contact between one of the legs 23 and one of the cams 25, in which an electrical connection is made through an electrical line, not shown in detail, to a control center, would be generated into a lamp and/or an acoustic indicator.
  • this could also be done mechanically or electrically using another known indication element.
  • reinforcing frame 32 connecting the four legs 23, which consists of a lattice construction, but could also be designed as a ring or something similar.
  • the purpose of this reinforcing frame 32, which has a cover 33 on the front, is to ensure that the legs 23 and with them the coupling or connecting head 20 are held stably in the housing structure.
  • the coupling or connection head 20 with the reinforcing frame 32 is advantageously also made in one piece.
  • the housing structure 15 is supported with several feet 45 on the underside on at least one, preferably on two multi-part support units 35 in the vehicle body.
  • These support units 35 are each composed of a bracket 36 extending below the housing structure and screws 37 that can be actuated laterally to the housing structure 15 and can be screwed into the vehicle body. These support units 35 enable the housing structure to be positioned during assembly and thus easier installation of the device 10.
  • two wedges 39 held by a connecting part 38 are provided on the back of the housing structure 15, each of which is in contact with a wedge surface on an end web 41 of the housing structure 15.
  • the wedges 39 can be adjusted in height transversely to the axial direction A, which is advantageously done at the end of the installation of the device in the vehicle body.
  • two fastening elements 43 are arranged in parallel in the longitudinal direction of the wedges 39 and can be screwed into a transverse axis 44 which can be fastened in the housing structure 15.
  • the back sides 39' of the wedges 39 are in contact with a corresponding wall of the vehicle body.
  • the wedges 39 are adjusted upwards until the housing structure 15 is permanently clamped between these wedges 39 and clamping jaws (not shown) in the vehicle body, which engage the front ends 15 'of the housing structure 15.
  • the corresponding sliding guides of the coupling or connecting head and the housing structure could be designed differently, for example as slide rails and rollers guided on them, instead of as dovetail-shaped guide tracks.
  • the coupling or connection head could in principle also be guided on the outside of the housing structure.
  • the sliding guides on the coupling or connecting head would then be arranged on the inside and those of the housing structure on the outside.
  • the housing structure and with it the coupling or connecting head could, for example, be tubular or rectangular in cross section with rounded corners.
  • These sliding guides could accordingly also have a round, polygonal or other shape in cross section and be secured against rotation or torsionally rigid.
  • This at least one stop cam 25 in the housing structure and the at least one corresponding stop surface 24 on the respective leg 23 could theoretically be omitted. In a simpler embodiment of the device 10, it could be built without such an indication element and without this reinforcing frame.
