Definitions

  • the present invention relates generally to a coupling for mixed coupling between an automatic central buffer coupling and a towing hook of a rail-guided vehicle, in particular a rail vehicle.
  • the coupling is suitable, for example, as a transition coupling or shunting coupling for track-guided vehicles.
  • the invention also relates to a corresponding pull rod for such a coupling.
  • a coupling of the type contemplated herein is, in particular, a special purpose automatic coupling commonly fitted or attachable to shunters (shunters) and capable of being controlled by the vehicle shunter.
  • the coupling according to the invention is used in particular for adapting couplings of different types in order to enable mixed coupling between an automatic central buffer coupling and a towing hook of a rail vehicle.
  • a generic coupling is generally known from rail vehicle technology and is used to connect rail vehicles that are equipped with different coupling systems (for example, Scharfenberg ® coupling on towing hook).
  • the attachment of the coupling, for example, to the towing hook of a track-guided vehicle is usually done manually, while the coupling process with the central buffer coupling can take place automatically.
  • a conventional coupling for mixed coupling between an automatic central buffer coupling and, for example, a towing hook of a track-guided vehicle usually has a coupling carrier that is at least partially designed as a housing, in which a coupling lock can be accommodated for mechanically connecting the coupling to a coupling head of an automatic central buffer coupling provided dome closure.
  • a coupling carrier that is at least partially designed as a housing, in which a coupling lock can be accommodated for mechanically connecting the coupling to a coupling head of an automatic central buffer coupling provided dome closure.
  • the face of the coupling then rests against the face of the coupling head of the automatic central buffer coupling.
  • a coupling bracket can be provided as the interface structure of the towing hook module, which can be accommodated, for example, in the towing hook of a track-guided vehicle and can therefore ensure a mechanical connection of the coupling to the towing hook of the track-guided vehicle.
  • the towing hook of the track-guided vehicle introduces tensile and compressive forces into the interface structure of the towing hook module, which is designed as a coupling bracket.
  • the compressive forces introduced into the coupling bracket or into the towing hook module are conducted via a supporting structure of the coupling to the face of the coupling and from there to the face of the coupling head of the automatic central buffer coupling, which is mechanically connected to the coupling.
  • the coupling locks can have, for example, a frog which is rotatably mounted via a main bolt relative to the supporting structure of the coupling and has a coupling eyelet articulated thereto. In doing so, a tractive force is transmitted via the respective coupling eyelets, which are engaged in the corresponding frogs.
  • FIG. 1 A coupling of the type mentioned at the outset that is known from the prior art is FIG. 1 in a side view and in FIG. 2 shown in an isometric view.
  • this conventional coupling 101 is placed on the towing hook 50 of a track-guided vehicle.
  • the coupling 101 is provided on both sides at its rear end with carriers 103, 103' which are arranged parallel at a distance from one another and are of identical design and which are connected to one another at the free ends by a bolt 104.
  • the bolt 104 holds the coupling 101 in the mouth of the towing hook 50.
  • An angle lifter 105 is arranged on both sides of the conventional coupling 101 .
  • a first link 105a of the angle lifter 105 is designed to be telescopically slidable.
  • the first link 105a which is held in the extended position by a compression spring 109, is articulated on the coupling 101.
  • a second link 105b of the angle lever 105 is designed as a rigid link.
  • the first and second links 105a, 105b are connected to one another at their respective free ends by a common yoke 107.
  • An adjusting nut 106 is guided centrally through the yoke 107 and, for support on the nose of the draw hook 50, carries a web 108 which is recessed in the form of a cap on the underside.
  • the links 105a, 105b on both sides of the coupling 101 are connected to one another and to one another by a common axis 110, the axis 110 serving as a contact surface on the end face of the towing hook 50, so that by fixing the web 108 the vertical angular position of the coupling 101 by the bolt 104 and thus the center position of the clutch 101 is adjustable.
  • Another clutch that can be used in particular as a shunting clutch for track-guided vehicles is, for example, from EP 2 529 994 A1 known.
  • the coupling known from this prior art is characterized in that it can be connected to different couplings, so that different maneuvering tasks can be performed with one and the same coupling without changing the coupling and while minimizing set-up times.
  • this coupler can be used to couple both mainline couplers and metro couplers without the need for manual intervention by the operator.
  • coupling head changer which is used for the automatic replacement of coupling heads of different designs and/or different types in a vertical coupling plane defined by the coupling.
  • This coupling head changer is hung on the towing hook of a track-guided vehicle using a relatively complex arrangement.
  • the invention is based on the object of specifying a coupling which can be connected with different automatic couplings, in particular mainline or metro couplings or similar central buffer couplings on the one hand and with screw couplings on the other while minimizing set-up times, so that different shunting tasks can be carried out without having to Coupling and in particular a tow hook module of the coupling must be removed from the tow hook of the track-guided vehicle and an originally made height centering of the coupling is no longer necessary.
  • a clutch should be specified, with which not only a tow hook one track-guided vehicle can be coupled automatically, but also mainline couplings and optionally metro couplings can be coupled.
  • this object is achieved by a coupling which has a pull rod with the features of independent patent claim 1, advantageous developments of this pull rod being specified in the dependent claims.
  • the invention relates in particular to a drawbar for a coupling of a track-guided vehicle, in particular a rail vehicle, or a coupling with a drawbar, the drawbar having a first end region on the wagon body, via which the drawbar can be connected to a wagon body, preferably in a detachable manner.
  • the pull rod also has a second end region opposite the first end region, and this second end region can be provided with a joint arrangement via which the coupling head of an automatic coupling can be swiveled into a horizontal coupling plane, if necessary.
  • the first end region of the drawbar on the car body side is pivoted in the vertical plane by means of a bolt on a drawbar of a track-guided vehicle, in particular a shunting vehicle, and is supported against lowering below the approximate horizontal position. In this position it is possible to couple with the towing hook of an adjacent car body, the eye of the coupling falling into the towing hook mouth of the car body to be coupled.
  • the coupling or the pull rod of the coupling is suspended on the towing hook bolt in such a way that the coupling or the towing hook of the coupling can be brought from a substantially horizontal position to a vertical position, so that the towing hook arranged at the front of the shunting vehicle becomes free for coupling with the towing hook of an adjacent car body.
  • the joint arrangement is formed on the first end area of the pull rod on the car body side, or is formed by the first end area of the pull rod on the car body side if this end area is attached to the tow hook of the shunting vehicle so that it can pivot in the vertical plane with the aid of a bolt.
  • the joint arrangement is provided on the second end region opposite the first end region of the pull rod, so that the coupling head of an automatic coupling can be pivoted into the horizontal coupling plane via this joint arrangement, if necessary.
  • the joint arrangement of the pull rod to have a first joint arm that can be pivoted about a horizontal axis and to which a coupling head of an automatic coupling is or can be fastened or fastened, preferably detachably and/or interchangeably.
  • the first articulated arm has an interface area via which a coupling head of an automatic coupling can be attached to the first articulated arm in an exchangeable manner.
  • the interface area to have at least one shell sleeve arrangement.
  • the interface area basically serves to mechanically connect the first articulated arm of the pull rod to a support structure of a coupling head, in particular an automatic coupling head, in a detachable manner.
  • a modular or modular design of the coupling consisting essentially of the drawbar and a coupling head designed separately from it can be realized in this way, with a coupling head of a special design or a special type being attached to one and the same drawbar of the shunting vehicle as required the vertical coupling plane defined by the coupling can be brought (pivoted in) so that the coupling can then be automatically connected to a corresponding counter-coupling head of an adjacent vehicle that is to be maneuvered, for example.
  • the coupling according to the invention is suitable for coupling to vehicles with couplings of different designs or types, with the coupling in particular not having to be changed or replaced by the towing hook of the shunting vehicle.
  • the clutch according to the invention different shunting tasks can be fulfilled in particular, so that this is a system that can be used in an extremely flexible manner.
  • the pull rod has an interface area via which the first articulated arm of the pull rod is mechanically connected or can be connected detachably to the supporting structure of a coupling head.
  • the interface area makes sense here for the interface area to have at least one shell sleeve arrangement.
  • the interface area can also have at least one locking pin arrangement with at least one locking pin.
  • the socket pin arrangement had a first receiving area that was contoured at least in certain areas and a second receiving area that was designed to be complementary thereto at least in some areas, with the first and second receiving areas of the socket pin arrangement preferably being or being detachably connected to one another via at least one locking pin.
  • the articulated arrangement of the drawbar has a second articulated arm which can be pivoted about the horizontal axis and on which a towing eyelet and in particular a towing eyelet which is compatible with a towing hook of the shunting vehicle is or can be fastened. It is provided here that the second articulated arm is connected to the first articulated arm of the tie rod in such a way that both articulated arms can be pivoted together, in particular exclusively together, about the horizontal axis.
  • an energy-absorbing and/or damping element is integrated in the pull rod of the clutch to dampen tensile and/or compressive forces transmitted via the pull rod during driving.
  • the energy absorption and/or damping element is preferably regenerative, for example in the form of a spring device or a spring assembly.
  • FIG. 1 and FIG. 2 a coupling 101 known from the prior art is shown, which has an angle lifter 105 for height centering, which is fastened via a yoke 107 on the nose of a towing hook 50.
  • the angle lifter 105 is fastened to the side of the housing 102 of the coupling 101 and ensures that the coupling 101 is vertically centered.
  • FIG. 1 and in FIG. 2 The coupling 101 shown can be seen in the fact that due to the relatively complicated structure of the device for height centering in the form of an angle lifter 105, the assembly of the coupling 101 on the towing hook 50 of a coupling to be adapted is relatively difficult to carry out. In particular, it is not It is possible to mount the coupling 101 on the towing hook 50 of a coupling to be adapted by one person alone, since the coupling 101 cannot be held by one person and the device for height centering can be correctly attached to the towing hook 50 at the same time.
