Description
- This is a continuation of PCT application No. PCT/EP2019/050085, entitled “ADAPTER PART FOR ADAPTING A COUPLING HEAD, COUPLING HEAD HAVING AN ADAPTER PART AND METHOD FOR ADAPTING A COUPLING HEAD”, filed Jan. 3, 2019, which is incorporated herein by reference.
- The present invention generally relates to the adaptation of couplings, in particular of track-bound vehicles, such as rail vehicles. In detail, according to a first aspect, the present invention relates to an adapter component for adapting a coupling head of a first construction type with a coupling head of a second construction type. The coupling head of the second construction type may be different from the coupling head of the first construction type. According to another aspect of the present invention, the present invention also relates to a corresponding coupling head having such an adapter component for providing a transition coupling. The present invention also relates to a method for adapting a coupling head of a first construction type to a coupling head of a second construction type.
- Transition couplings are used in vehicles with different coupling types or coupling heights, for example, when shunting and towing. To this end, special embodiments have previously generally been used in order to be able to releasably connect or couple corresponding coupling heads of different coupling types to each other. A common approach is to provide a so-called intermediate piece which can be connected, on the one hand, to the coupling head of a first construction type and, on the other hand, to a coupling head of a second construction type. Such an intermediate piece is, for example, described in the document DE 26 32 571 A1.
- The conventional approach, that is to say, to adapt coupling heads of different construction types using an intermediate piece is, however, only conditionally suitable for situations in which a coupling head of the “Janney” construction type can be connected to a coupling head of another construction type since, as a result of the function of a coupling head of the “Janney” construction type, an intermediate piece can generally only be effectively connected to the coupling head of the “Janney” construction type using additional construction components, such as resilient elements, threaded rods, lateral sprues (wing pocket), in order to achieve a corresponding vertical fixing.
- What is needed in the art is an improved transition coupling for a coupling head.
- The present invention provides a transition coupling or an adapter component for adapting a coupling head of a first construction type, in particular of the “Janney” construction type, with a coupling head of a second construction type, wherein no additional components are required for vertical fixing. Another object of the present invention involves providing a transition coupling for a coupling head, in particular of the “Janney” construction type which is more durable.
- According to embodiments of the adapter component according to the invention, in this context there is provision for the adapter component to have a first region which at least partially faces the coupling head of the first construction type which is intended to be adapted and which has at least in some regions a contour which is adapted to the coupling mouth. In particular, the first region of the adapter component is constructed to accordingly complement projections or protuberances which are formed in the coupling head body of the coupling head which is intended to be adapted and which during “normal” operation of the coupling head bring about a vertical fixing of the articulated jaw in the closed position thereof.
- These protuberances formed in the coupling head body, in particular of a coupling head of the “Janney” construction type are, for example, described in detail in the document U.S. Pat. No. 1,054,298 A. For reasons of simplification of this description, with regard to the cooperation of these protuberances with the articulated arm of the coupling head and in the figurative sense the cooperation of the protuberances with the adapter component used in place of the articulated arm, reference may be made to the description of U.S. Pat. No. 1,054,298 A.
- However, it should be noted at this point that the present invention is not limited to embodiments in which in the coupling head housing of the coupling head which is intended to be adapted corresponding protuberances, as described in U.S. Pat. No. 1,054,298 A, is limited. Instead, the notion of the present invention involves using the components of the coupling head which is intended to be adapted and in particular the components of the corresponding coupling head housing with regard to the vertical fixing of the adapter component which are used during the “normal” use of the coupling head to fix the articulated arm in the closed position.
- Alternatively or additionally to the above-described embodiments, according to embodiments of the adapter component according to the present invention, there is provision for the adapter component to have a second region which at least partially faces the coupling head of the first construction type which is intended to be adapted, in particular of the “Janney” construction type, and which is constructed with regard to the closure mechanism of the coupling head of the first construction type which is intended to be adapted in such a manner that the adapter component in the state thereof at least partially received in the coupling mouth of the coupling head which is intended to be adapted is fixed to the coupling head housing by the closure mechanism and in particular also fixed in a vertical direction.
- That is to say, according to these embodiments, the adapter component is a type of “hybrid” which has structural features of the articulated jaw (which is replaced by the adapter component) of the coupling head which is intended to be adapted, on the one hand, and structural features of the articulated jaw of a counter-coupling of the same construction type.
- In this context, it is particularly advantageous for the second region of the adapter component to have at least in some regions a contour which corresponds to a contour of a region of the articulated jaw which cooperates with the closure mechanism. Consequently, the closure mechanism provided inside the coupling head body of the coupling head which is intended to be adapted, in particular a locking system, such as a drop bolt and bolt lifter, can be used to fix the adapter component.
- Nonetheless, it is advantageous for the adapter component to have a perpendicular receiving member, in particular hole, for receiving the perpendicular pin of the coupling head which is intended to be adapted, that is to say, for receiving the perpendicular pin of the coupling head which is intended to be adapted, which pin in the “normal” state of the coupling head which is intended to be adapted rotatably supports in a horizontal manner the articulated jaw which is replaced by the adapter component.
- According to embodiments of the solution according to the present invention, the adapter component has another (third) region which faces away from the coupling head of the first construction type which is intended to be adapted and which is configured at least in some regions in a complementary manner to the coupling head of the second construction type and which is constructed to form a releasable connection to the coupling head of the second construction type.
- Alternatively, the adapter component is constructed in a modular manner and has another (third) region which faces away from the coupling head of the first construction type to be adapted and which is configured as an interface region and constructed to releasably retain or fix a transition portion which is constructed at least in some regions in a complementary manner with regard to the coupling head of the second construction type in such a manner that it can be releasably connected to the coupling head of the second construction type. With regard to the interface region of the modular adapter component, it has been found to be advantageous for it to have a tooth arrangement which is constructed to receive a correspondingly complementary counter-tooth arrangement of the transition portion preferably in a positive-locking manner at least in some regions. As a result of such a tooth arrangement, an additional fixing can be achieved, in particular in the X and Y direction. Of course, however, other embodiments may also be considered for the interface region.
- In brief summary, it consequently remains to be noted that the adapter component is constructed in such a manner as to form an at least substantially play-free, releasable connection of the adapter component to the coupling head body of the coupling head of the first construction type which is intended to be adapted, wherein no additional components are required for this in order in particular to bring about a fixing in the Z direction (vertical direction).
- The present invention relates not only to an adapter component which replaces the articulated jaw of a coupling head which is intended to be adapted in order to thus form a transition coupling, but also to a coupling head of an in particular track-bound vehicle which is constructed as a transition coupling, in particular a rail vehicle, wherein the coupling head has a coupling head body with a Janney contour and an adapter component, in particular an adapter component of the type mentioned above.
- The adapter component of the coupling head which is configured as a transition coupling is constructed at least in some regions in a complementary manner to a coupling mouth of the coupling head and is at least partially received in the coupling mouth and releasably fixed at that location using a closure mechanism of the coupling head.
- The adapter component according to the coupling head which is configured as a transition coupling further has a region which faces away from the coupling mouth and which is either constructed at least in some regions in a complementary manner to the coupling head of a counter-coupling in such a manner that it can be releasably connected to the coupling head of the counter-coupling, or which is configured as an interface region and constructed to releasably retain a transition portion which is constructed at least in some regions in a complementary manner with regard to the coupling head of a counter-coupling in such a manner that it can be releasably connected to the coupling head of the second construction type. The latter embodiment then forms a modular coupling head of a transition coupling.
- Finally, the present invention further relates to a method for adapting a coupling head of a first construction type to a coupling head of a second construction type. The coupling head of the first construction type considered in this method has a coupling head body having a coupling mouth, an articulated jaw which can be rotated horizontally about a perpendicular pin relative to the coupling head body between a ready position for coupling and a closed position and a closure mechanism for locking or unlocking the articulated jaw in the closed position thereof as necessary. In order to adapt such a coupling head, in the method according to the present invention there is provision for the articulated jaw of the coupling head which is intended to be adapted to be replaced with an adapter component, in particular an adapter component of the above-mentioned type, wherein the adapter component has a first region which faces the coupling head of the first construction type to be adapted and which at least in some regions has a contour which is adapted to the coupling mouth.

- In order to explain the coupling principle with coupling heads of the “Jenney” construction type, reference is made below to the illustrations in
FIGS. 1A to 1C .FIGS. 1A to 1C schematically show the coupling principle of a coupling head of the first construction type which in this instance is the “Janney” construction type. - In detail,
FIG. 1A schematically shows afirst coupling head 1 of the “Janney” construction type and a correspondingcounter-coupling head 1′ of the same construction type in the state ready for coupling. Thecoupling head body lateral rigidifying horn jaw perpendicular pin FIG. 1A , the twocoupling heads - During the coupling operation (cf.
FIG. 1B ), the articulatedjaws coupling mouth jaw perpendicular pin jaw coupling head body - When the two
coupling heads jaw coupling head coupling head body FIG. 1C ). For decoupling, it is sufficient for an articulatedjaw jaws jaws - In the coupled state, there is produced a tensile force transmission between the coupling heads via the articulated jaws. However, pressure forces are transmitted via the pressure seat of the articulated jaws in the mouth of the coupling head body.
- If, in order to adapt a coupling head of the “Janney” construction type, a corresponding intermediate piece generally known from the prior art is now inserted into the mouth of the coupling head which is intended to be adapted—as already indicated—additional components are necessarily required in order to achieve vertical fixing of the intermediate piece. These additional components are necessarily located in the force path of a tensile force transmission which, in the event of a tensile force transmission, results in the tensile forces being carried out via the additional components which are provided to vertically fix the intermediate piece, which in turn significantly limits the maximum permissible tensile force.
- Furthermore, when an intermediate piece is used for adapting a coupling head of the “Janney” construction type, the force transmission would be dependent on the play of the articulated jaw of the coupling head which is intended to be adapted and the intermediate piece in the X and Y direction.
- The solution according to the present invention is particularly suitable for adapting a coupling head which has a coupling head body, an articulated jaw which can be rotated horizontally about a perpendicular pin relative to the coupling head body between a ready position for coupling and a closed position and a closure mechanism for locking or unlocking the articulated jaw as necessary in the closed position thereof.
- With regard to such a coupling head which is intended to be adapted and which can be a coupling head of the “Janney” construction type, according to the present invention there is proposed an adapter component which is constructed, in place of the articulated jaw of the coupling head which is intended to be adapted, to be releasably connected to the coupling head and in particular the coupling head body of the coupling head which is intended to be adapted.
- That is to say, in place of an intermediate piece, as known, for example, from the document DE 26 32 751 A1, according to the present invention, in place of the articulated jaw of the coupling head which is intended to be adapted, an adapter component is used. It is thereby ensured that the adapter component can be securely fixed to the coupling head body of the coupling head which is intended to be adapted without additional components being required for this to vertically fix the adapter component.
- It is particularly possible to dispense with such additional components for vertically fixing the adapter component since according to the solution according to the present invention the adapter component replaces the articulated jaw of the coupling head which is intended to be adapted and consequently in the same manner as the replaced articulated jaw is fixed securely by the structure of the coupling head body and the structure of the coupling head, in particular also in a vertical direction.
- As already set out in the introduction to the description with reference to the illustrations in
FIGS. 1A to 1C , the coupling head of the first construction type considered in particular in this publication (such as, for example, a coupling head of the Janney construction type) is characterized in that the coupling head body of the coupling head has a coupling mouth which is constructed in a state, when the coupling head is coupled to a complementary counter-coupling head, to at least partially receive the articulated jaw of the counter-coupling head. - Coupling head body closed position coupling head body closed position coupling head body coupling head body coupling head body coupling head body coupling head body ready position closed position closed position closed position 4A5A
- It should be appreciated that the adapter components or transition couplings illustrated by way of example in the drawings relate in particular to coupling heads of the “Janney” construction type.
- The Janney coupling is an automatic coupling for rail vehicles, extensively used in railways in North America and in South Africa. It is the coupling type with the highest level of durability and also enables the formation of trains a kilometer long. In the USA, this coupling is almost always referred to as an “Automatic coupler”. Officially, it is called the AAR coupler (AAR is the abbreviation of the standard organization “Association of American Railroads”) or Knuckle Coupler. There are a few compatible variants of this coupling, the non-rigid configuration used in particular in goods traffic or the embodiment which is also referred to in passenger trains and railcars as a “Tightlock Coupler”.
- The coupling principle of these coupling types is schematically illustrated in
FIGS. 1A to 1C . - The
coupling head body 2 of thecoupling head 1 of this construction type has a Janney contour withlateral rigidifying horn 3 and pocket 4 and an articulatedjaw 6 which can be rotated horizontally on avertical pin 5. Not illustrated are the components of a closure mechanism located inside thecoupling head body 2, in particular the locking system, such as a drop bolt or bolt lifter, which can be activated, for example, by way of a bolt shaft which extends outwards. - The
coupling head 1 is ready for coupling when the articulatedjaw 6 protrudes outwards. When twocoupling heads jaw 6 is rotated by the action of thecounter-coupling head 1 into the closed position in which it is blocked by way of a bolt of the locking mechanism which, for example, falls downwards. For decoupling, it is sufficient for an articulatedjaw 6 to be unlocked by the closure bolt being lifted. When the coupling heads 1, 1′ are separated, the articulatedjaws jaws - Referring now to
FIGS. 2-3 , there is shown schematic illustrations of another exemplary embodiment of acoupling head 1 of the first construction type, i.e., the “Janney” construction type, in the state thereof coupled to acounter-coupling head 1′ of the same construction type. -
FIG. 2 is a schematic illustration of a region of acoupling head body 2 of acoupling head 1 of the first construction type, showing in detail correspondingly protrudingregions 7 and recesses in thecoupling head body 2, wherein these projecting regions 7 (“protuberances”) are highlighted using the circles inFIG. 3 . The protuberances/components 7 provided in the coupling head housing of thecoupling head 1 vertically fix the articulatedjaw 6 of thecoupling head 1 in the closed position thereof. In other words, thesecomponents 7 serve in thecoupling head 1 according to the first construction type to fix the articulatedjaw 6 in the closed position thereof, in particular to fix it in a vertical direction. - As will be set out in greater detail below, the adapter component according to the invention makes use of this function since the features which are provided in the
coupling head body 2 of thecoupling head 1 which is intended to be adapted and which are used to fix the articulatedjaw 6 of thecoupling head 1 which is intended to be adapted in the closed position thereof, are used accordingly to fix theadapter component 10 which is used in place of the articulatedjaw 6. -
FIGS. 4A to 4D are different schematic views of a first exemplary embodiment of theadapter component 10 according to the present invention. - In detail, the
adapter component 10 according to the first exemplary embodiment is constructed as a “modular” adapter component since thisadapter component 10 is constructed to connect a coupling head of the first construction type to acoupling head 1 of any second construction type. To this end, theadapter component 10 has aregion 13 which is configured as an interface region and constructed to releasably fix or retain a transition portion which is not shown in the drawings. The transition portion which is not illustrated in the drawings is constructed in a complementary manner at least in some regions with regard to the coupling head of the second construction type in such a manner that it can be releasably connected to the coupling head of the second construction type. - As illustrated in
FIGS. 4A to 4D , in the first exemplary embodiment of theadapter component 10, theinterface region 13 is provided with atooth arrangement 14. Thistooth arrangement 14 is in particular constructed to receive a correspondingly complementary counter-tooth arrangement of the transition portion which is not illustrated in the drawings, preferably in a positive-locking manner at least in some regions. The advantage of such atooth arrangement 14 is in particular that an additional fixing in the X and Y directions can be produced. - The
adapter component 10 according to the first exemplary embodiment is in particular constructed to be releasably connected to thecoupling head 1 of the first construction type, wherein for this purpose thecoupling head 1 of the first construction type which is intended to be adapted has been changed in such a manner that, in place of the articulatedjaw 6 which is generally used in thiscoupling head 1, theadapter component 10 is used. Theadapter component 10 is consequently constructed, for the fixing thereof to thecoupling head body 2, to make use of the features of thecoupling head body 2 which, in the “normal” state of thecoupling head 1 which is intended to be adapted serve to fix the articulatedjaw 6 of thecoupling head 1. - For example, the first exemplary embodiment of the
adapter component 10 according to the invention has afirst region 11 which at least in some regions has a contour which is adapted to thecoupling mouth 8 of thecoupling head 1 of the first construction type which is intended to be adapted. Thisregion 11 of theadapter component 10 is in particular constructed to correspond to the features (for example,protuberances 7 as shown inFIG. 2 ) which are provided in thecoupling head body 2 of thecoupling head 1 which is intended to be adapted and which were originally provided to fix the articulatedjaw 6 of thecoupling head 1 which is intended to be adapted at least in the closed position thereof. - Furthermore, in the first exemplary embodiment of the
adapter component 10 according to the invention, there is provision for it to have an additional (second)region 12 which, with regard to the closure mechanism of thecoupling head 1 of the first construction type which is intended to be adapted, is configured in such a manner that theadapter component 10 in the state in which it is at least partially received in thecoupling mouth 8 of thecoupling head 1 of the first construction type which is intended to be adapted is fixed by the closure mechanism to thecoupling head body 2. - This
second region 12 of theadapter component 10 has at least in some regions a contour which corresponds to a contour of a region of the articulatedjaw 6 of thecoupling head 1 which is intended to be adapted and which cooperates with the closure mechanism of thecoupling head 1 which is intended to be adapted. - The first exemplary embodiment of the
adapter component 10 according to the invention, as schematically illustrated inFIGS. 4A to 4D , may also be characterized in particular in that theadapter component 10 has a perpendicular receivingmember 15, in particular through-hole, which serves to receive theperpendicular pin 5 of thecoupling head 1 of the first construction type which is intended to be adapted, whichpin 5 in the “normal” operating state of thecoupling head 1 of the first construction type which is intended to be adapted rotatably supports in a horizontal manner the articulatedjaw 6 which is replaced by theadapter component 10. - In
FIGS. 4A and 4B , the first exemplary embodiment of theadapter component 10 according to the present invention is shown in a state in which theadapter component 10 is connected to thecoupling head 1 of the first construction type which is intended to be adapted, wherein in this state theadapter component 10 replaces the articulatedjaw 6 of thecoupling head 1 which is intended to be adapted. -
FIGS. 5A to 5B illustrate a coupling head assembly wherein the first exemplary embodiment of theadapter component 10 is coupled to acoupling head 1 of the first construction type. -
FIG. 6 is a schematic isometric view of another exemplary embodiment of theadapter component 10 according to the invention. - This second exemplary embodiment of the
adapter component 10 according to the invention substantially corresponds from a functional and structural viewpoint to the first exemplary embodiment according to the illustrations inFIGS. 4A to 4D . However, the second exemplary embodiment theadapter component 10 is constructed without a perpendicular receivingmember 15 or hole for receiving theperpendicular pin 5 of thecoupling head body 2. - While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
