Definitions

  • the invention relates to a train coupler adapter for connecting a coupler of a first geometry with a draw hook coupler.
  • the invention also relates to a system of such an adapter and a draw hook coupler.
  • the invention also relates to a train with a first car with a coupler of a first geometry and a second car with a draw hook coupler.
  • a train coupler adapter for connecting a coupler of a first geometry with a draw hook coupler
  • the disclosed adapter has a front section with an interface suitable to couple with a coupler of a first geometry and a rear section with an opening suitable for the tip of the hook of the draw hook coupler to be inserted into and a safety bracket at the rear section that has a traversing section that is positioned between the opening and that traverses over the opening.
  • the invention is based on the idea of making the safety bracket swivel relative to the rear section, while at the same time providing a blocking element that limits the swiveling motion of the safety bracket.
  • Such an arrangement allows the rear section to be attached to the hook of the draw hook coupler in an easy manner.
  • the safety bracket preferably is allowed to swivel relative to the rear section. If the safety bracket is allowed to swivel relative to the rear section, this allows the tip of the hook to be more easily introduced into the opening of the rear section, because the safety bracket will make room for the maneuvering of the rear section relative to the hook and will not be in the way of any relative motion of the hook relative to the rear section, be at transvers movements or rotational movements.
  • the invention does, however also provide the blocking element to limit the swivel angel of the safety bracket relative to the rear section. This allows to keep the safety bracket in a certain position/ in a certain area. This feature can, for example, be used to make sure that the safety bracket remains in a certain area once the hook has been connected to the rear section of the adapter and hence allows the safety bracket to be used as reassurance to prevent that the hook decouples from the rear section of the adapter.
  • the invention is directed to a train coupler adapter.
  • train coupler adapter These adapters are used, if a car of a train, for example a passenger car of a train is to be connected to different car of a train, for example a locomotive, for example a shunting lock (shunting locomotive), which might have a coupler geometry that is not suitable to couple with the coupler geometry of the first train of the car.
  • a train coupler adapter hence makes sure that it can be coupled to the coupler of the first car of the train as well as being coupled to the draw hook coupler of the second car of the train in such a manner that it allows towing and/or pushing forces to be transmitted from the first car of the train to the second car of the train or vice versa.
  • the adapter has a front section, this front section has an interface that is suitable to couple with a coupler of a first geometry.
  • the first geometry is the geometry of a central buffer coupling (German term: "Mittelpufferkupplung").
  • the first geometry of the coupler is a draw hook (German term: “Zughaken”), or the first geometry of the coupler is a automatic coupling, for example of the built-type "Scharfenberg” (German term: “Automatische Kupplung; Bauart Scharfenberg"), for example the couplers that have become known in the industry under the abbreviation "type 10", or the first geometry of the coupler is an automatic coupling of the type as they have become known in the industry under the names US AAR, India AAR, China type 17 or SA3, or the first geometry of the coupler is for example of a Albert coupler or of a Miller Hook and Platform coupler or of a Norwegian coupler or of a Johnston coupler or of a bell-and-hook coupler or of a Janney/MCB/ARA/AAR/APTA coupler or of a Willison/SA3 coupler or of a Westinghouse H2C coupler or of a WABCO N-Type or of
  • the interface at the front section of the adapter can be of a reduced design relative to the design of a complete coupler head of the first geometry. Often, it is sufficient for the purposes of shunting cars of a train to work with reduced designs on the interface of the adapter.
  • the interface of the adapter only needs to make sure that the adapter is attached to the coupler on the car of a train sufficiently securely for the traveling speeds of the shunting. Likewise, the interface needs to be sufficiently strong to allow the pushing forces and/or pulling forces that occur during shunting to be safely transmitted to the coupler on the car of the train.
  • the interface for these purposes need not have to have the electronic connections or the hydraulic connections that a fully designed coupler had would normally have.
  • the interface of the front section of the adapter is a coupler head that has all counter elements that a coupler head of a normal train of a car that would couple to the coupler of the car of the train would have, for example would also have the electronic connections and the hydraulic connections.
  • the adapter also has a rear section with an opening suitable for the tip of the hook of the draw hook coupler to be inserted into.
  • the opening can be a blindhole in the sense that the tip of the hook of the draw hook coupler remains inside the opening, once it is inserted into the opening.
  • the opening is, however, a through-opening that allows the tip of the hook to leave the opening on the opposite side to that side, on which the tip of the hook has been inserted into the opening.
  • the hook could for example be the hook of a draw hook coupler as shown in DIN 25 605 Blatt 1.
  • the adapter further has a safety bracket at the rear section.
  • the safety bracket has a traversing section that is positioned beneath the opening.
  • the traversing section traverses over the opening.
  • the traversing section does not traverse over the opening directly at the mouth of the opening, but is arranged at a distance to the mouth of the opening.
  • the term "beneath” is considered to describe the position of the traversing section relative to the rear section in a situation, where front section and the rear section are arranged in such a manner that the front section is arranged next to the rear section, but not immediately above or immediately below the rear section.
  • the safety bracket has a first arm arranged on one side of the rear section.
  • the first arm has a first part and a second part.
  • the first part of the first arm is attached to the rear section.
  • the attachment of the first part of the first arm to the rear section is provided in such a manner that it allows the second part of the first arm to swivel relative to the rear section.
  • This can, for example be obtained by providing the first part of the first arm with a through hole and by a bolt that bolts the first part of the first arm to the rear section to pass through this through-hole, whereby the first part of the first arm is held to the rear section by way of the bolt sufficiently loosely to allow a swivel movement of the second part of the first arm relative to the rear section.
  • bearings like bushes or ball bearings can be used as part of the connection of the first part of the first arm to the rear section.
  • the safety bracket also has a second arm.
  • the second arm is arranged on the opposite side of the rear section relative to that side, on which the first arm is arranged.
  • the second arm has a first part and has a second part.
  • the first part of the second arm is attached to the rear section. The attachment of the first part of the second arm to the rear section is provided in such a manner that it allows the second part of the second arm to swivel relative to the rear section.
  • bearings like bushes or ball bearings can be used as part of the connection of the first part of the second arm to the rear section
  • first arm and/or the second arm are punched parts.

  • the second part of the first arm includes one end of the first arm.
  • the second part of the second arm includes one end of the first arm.
  • the traversing section hence connects one end of the first arm with one end of the second arm.
  • the connection between the traversing section and the second part of the first arm and/or the connection between the traversing section and the second part of the second arm can be a fixed connection, for example a connection obtained by welding or by glueing.
  • connection between the traversing section and the second part of the first arm and/or the connection between the traversing section and the second part of the second arm can, however, also be a form-fit connection, for example by way of parts of the traversing section passing through openings in the second part of the first arm or the second part of the second arm.
  • These parts can be provided with locks, for example nuts that are screwed onto external threads provided on parts on the traversing section.
  • the adapter has a blocking element that limits the swivel angle of the first arm and limits the swivel angle of the second arm relative to the rear section.

  • the draw hook coupler is surrounded by other elements, e.g. buffers or other parts of a shunting locomotive, it might turn out difficult to access the adapter from the rear or from the sides. In such situations, it is helpful, if the placement and the taking-away of the blocking element can be conducted very easily from the front.
  • the blocking element has a main body.
  • the main body of the blocking element is a rigid body.
  • One purpose of the blocking element is to prevent that the first arm and the second arm swivel relative to the rear section further than a predefined limit.

  • the rear section has a first plate and has a second plate that is arranged parallel to the first plate.
  • the first plate and/or the second plate do not need to be plane plates. It is feasible that the first plate and/or the second plate have steps, creases, kinks or bends. For example, a design is feasible, where the first plate and the second plate are connected directly to each other at a first end and then each have a bend section, which allows a mouth to be provided by the first plate and the second plate. Such an arrangement would still be considered to have the second plate arranged parallel to the first plate.

  • a bolt passes between the first plate and the second plate.
