Definitions

  • the present invention relates to a coupling arrangement for a rail vehicle, in particular for a tram, metro, light rail or a rail vehicle, further comprising a rail vehicle having the coupling arrangement and a method for coupling the rail vehicle with a second rail vehicle.
  • a central buffer coupling which has a pull and push rod with a coupling head arranged thereon.
  • the pull and push rod is connected to a train and pressure acting buffer device, which is fixed by means of a rotary joint pivotally in the horizontal direction on the frame of the rail vehicle.
  • a protective device is furthermore provided, which is arranged on the central buffer coupling and can be pivoted therewith. This protective device has on both sides of the coupling head arranged guard, which are connected via support rods to the frame.
  • a rail vehicle is specified with a central buffer coupling.
  • a horizontally pivotable cover which covers a passage opening for the central buffer coupling.
  • the cover has two cover elements attached to both sides of the coupling head, which are each secured with a support rod on the undercarriage of the vehicle and are held horizontally pivotable on the undercarriage together with the center buffer coupling articulated in a bearing.
  • EP 2 177 416 A1 further discloses a rail vehicle having a center buffer coupling.
  • the coupling has a coupling head and a coupling rod which connects the coupling head to the vehicle housing in an articulated manner.
  • rail vehicles in particular tram vehicles, front bumper, which absorb impact forces and forward into the undercarriage of the vehicle when the vehicle is not coupled to the bumper having vehicle end with another vehicle.
  • the coupling rod If the coupling rod is to be pivoted from an operating position to a parking position, the shock bar must be folded up. Special devices are often used for this purpose.
  • the bumper is generally very heavy, so that the transfer of the coupling rod from the parking to the operating position and vice versa is cumbersome.
  • certain operations must be carried out in an area below the driver's cab of the rail vehicle, which is time-consuming and laborious. For example, it is necessary to shorten the coupling rod by pivoting a front relative to a rear rod segment, so that the rod can be stowed below the cabin area.
  • the present invention seeks to find means that allow a simple and quick retrofitting of the rail vehicle from the traction mode in a single vehicle operation or vice versa, the clutch assembly should be easily transferred from an operating in a parking position and vice versa.

  • the possible pivoting range of the pull and push rod is, for example, ⁇ 30 °.
  • the distance of the coupling head 120 from an imaginary axis of rotation for the coupling rod may be, for example, 1755 mm, as in the conventional coupling arrangement.
  • the locking elements 265 are to be attached to the damping elements 260, and the removable locking element 170 on the carriage 130 is to be removed.
  • the pull and push rod 114 is pivoted from the transverse position into a longitudinal position, wherein the carriage is moved in a central position on the carriage guide rails 155.
  • the locking pin is attached again.
  • a second embodiment of the present invention is shown ( Fig. 13 ), and only the elements and functions that differ from those of the first embodiment will be described and shown. Unless otherwise stated, the clutch assembly 100 in this second variant corresponds to that in the first variant.
  • the carriage 130 in the case of the second variant on no guide grooves for sliding contact with the carriage guide device.
  • guide rollers 136 which are in the form of tapered rollers and which taper away from the guide jaws, rest on the guide jaws 131, 132 of the carriage (FIG. Fig. 13b, 13c ).
  • the guide rollers are located on the slide guide rails 155 facing sides of the guide jaws and are arranged so that they receive the guide rails in the assembled state between each ( Fig. 13b ).
  • the carriage guide rails sit on the flanks of the tapered rollers so that the carriage can be moved practically without friction between the rails ( Fig. 13a ).
  • the tapered rollers are mounted on the guide jaws by means of guide roller shafts 137 so that their axes of rotation are perpendicular. If between the carriage guide rails and the respective outer side of the guide jaws 131, 132 a sufficient distance (clearance) is provided, the coupling rod 110 can be tilted in the vertical direction upwards and downwards by an angle ⁇ (see accordingly Fig. 4 ).
  • a third embodiment of the present invention is shown ( Fig. 14 ), describing and showing only those elements and functions different from those of the first and second embodiments.
  • the clutch assembly 100 in this third variant corresponds to those in the first and second variants.
  • the carriage guide device 150 is formed in this case not by circular segment curved carriage guide rails, but by plate-shaped carriage guide elements 155 (slide guide plates), the shape of a substantially circular segment-shaped carriage guide and support 156 for the carriage through Grooves 158 is formed follows.
  • plates other designs may be used, provided that therein Accommodate grooves, for example, rod-shaped elements.
  • These two plates are, as in the case of the carriage guide rails of the first and the second embodiment variant, arranged parallel to one another and spaced apart from each other, so that a carriage 130 can be movably arranged therebetween.
  • These plates are as well as the carriage guide rails mounted on both sides via damping elements 260 on the support structure 200 of the rail vehicle 500 (corresponding to Fig. 9 ).
  • the carriage guide elements have at their mutually facing sides in each case a guide groove 158, which forms the carriage guide 156.
  • This groove preferably extends in a circular segment over a substantial part of the length of the plates and are arranged in the slide guide device 150 exactly opposite each other.
  • the grooves are designed so that rollers 136 can engage in them. If, as in the case of the second embodiment, the rollers are tapered rollers, the grooves can likewise have a conical cross-section, adapted to the tapered rollers ( Fig. 14b, 14c ). So that the rollers in the grooves can run as smoothly as possible, their inner dimensions are slightly larger than the diameter of the rollers.
  • this game also determines the scope in which the coupling rod in the vertical direction upwards and downwards can be deflected by an angle ⁇ (see accordingly Fig. 4 ).
  • the rollers 136 sit as in the case of the carriage 130 in the second embodiment on the outer sides of the guide jaws 131, 132, arranged in rows but in this variant. In the embodiment shown, two rollers are arranged on each guide jaw. If more than two rollers are to be provided, they must also be arranged according to the curvature of the guide groove 158 in a formation corresponding to the curvature.
  • the rollers are each mounted on axes 137 rotatably mounted on the guide jaws.
  • the disassemblable locking member 170 for locking the coupling rod 110 is not located at a position in the carriage 130 adjacent the shaft 112 when in the operative position but penetrates the shaft so that the rod engages the shaft the operating position is held immovable. Therefore, no second permanently mounted locking pin is required.
  • This embodiment provides an opposite to the locking system of Fig. 5 different embodiment. Instead of the locking system shown here can also in Fig. 5 shown system in the in Fig. 14 shown embodiment variant can be used.
