Description

The invention relates to a coupling head of an automatic central buffer coupling according to the preamble of independent claim 1.

Accordingly, the invention particularly relates to a coupling head of an automatic central buffer coupling, which has a Willison profile with a large coupling claw and a small coupling claw, wherein the coupling head a line coupling is arranged with at least one coupling part for coupling lines, in particular of pneumatic brake lines and / or supply lines , but also electrical supply lines or signal lines, between two adjacent car bodies of a track-guided vehicle, in particular rail vehicle.

Central buffer couplings with Willison coupling heads are used for mechanically connecting two adjacent car bodies, for example a rail vehicle, and are distinguished by their robust construction, so that such coupling heads are frequently used in freight car couplings. The structure and operation of a coupling head type Willison are, for example, in the document DE 1 455 242 A described.

Technically, SA-3 type central buffer couplings represent a further development of the Willison coupling. Accordingly, the coupling head of an SA-3 type central buffer coupling also has a Willison profile with a large coupling claw. a small clutch claw and a coupling pocket arranged between the clutch claws.

Another central buffer coupling widely distributed in Europe for freight cars is the AK 69e central buffer coupling, whose coupling head is also provided with a Willison profile. Central buffer couplings of the type AK 69e are still frequently used in particular as ore wagon couplings. Due to the Willison profile, to form a mechanical connection between two adjacent car bodies, for example of a rail vehicle, the coupling head of an AK 69e central buffer coupling can also be coupled to the coupling head of a SA-3 or Willison type central buffer coupling.

Although a coupling head of an AK 69e central buffer coupling may be coupled directly to the coupling head of a Willison or SA-3 type central buffer coupling to form a mechanical connection between two adjacent bodies, the respective air line couplings of the different types of coupling are not matched to each other a direct coupling capability of the air line coupling of a coupling head belonging to a type AK 69e center buffer coupling with an air line coupling of a coupling head belonging to a Willison or SA-3 middle buffer coupling is not given.

Based on this problem, the invention has for its object to provide a coupling head of a central buffer coupling of the type mentioned, which is mechanically coupled for transmitting tensile and compressive forces to the coupling head of a counter-coupling of the same type, wherein the coupling process between the adjacent car bodies and the lines , in particular the pneumatic brake lines and / or supply lines, are automatically coupled together.

Furthermore, it was regarded as an object that the coupling head should be compatible with the coupling head of a central buffer coupling type AK 69e, wherein the line coupling of the coupling head without use of an accessory directly with the air line coupling of the coupling head of the central buffer coupling type AK 69e is detachable.

These objects are achieved by the subject matter of independent claim 1. Advantageous developments of the solution according to the invention are specified in the dependent claims.

Accordingly, the solution according to the invention is characterized in particular by the fact that in a coupling head of the type mentioned above in the region of the large coupling claw, a first rigidifying member, preferably in the form of a coupling horn, and in the region of the small coupling claw a second laminating member complementary to the first laminating member, preferably in FIG Formed a clutch bag, and in that a lever mechanism is provided for automatically ancestor of the coupling part of the line coupling from a first retracted position to a second, in the direction of the coupling plane advanced position, wherein the lever mechanism is actuated by the formation of an engagement of the second Starrmachungsorgans with a correspondingly complementary trained for this purpose Starrmachungsorgan a counter-coupling head when coupling the coupling head with the counter-coupling head.

Since the coupling head according to the invention has on the one hand a Willison profile and, on the other hand, a construction based on the type Willison / SA-3 coupling, a direct mechanical coupling capability of the coupling head according to the invention with operationally well-known Willison / SA-3 coupling heads is ensured. In addition, the Willison profile of the coupling head according to the invention ensures a direct coupling ability to a coupling head of a central buffer coupling type AK 69e.

In addition to the mechanical detachability with existing coupling heads type Willison, SA-3 and AK 69e, the coupling head according to the present invention is characterized in that the coupling head, a line coupling is arranged, which has a coupling part, the coupling of the coupling head with the Coupling head of a counter-coupling is movable from a first, retracted position into a second, in the direction of the coupling plane advanced position relative to the coupling head. In particular, when the coupling head is coupled with a coupling head of the same type, when forming the mechanical connection between the two coupling heads automatically move the corresponding coupling parts of the line couplings in each case in the second, advanced position. In this second, advanced position are the coupling parts the line couplings in the common vertical center longitudinal plane of the two coupling heads, so that the line couplings are directly coupled together in their second position.

Specifically, the front end portion of the coupling portion of the pipe coupling in the advanced (second) position in the intersection of the vertical coupling plane and the vertical longitudinal sectional plane of the coupling head, preferably at the level of the horizontal plane of an air duct coupling arranged on a coupling head of type AK 69e to the Kuppelbarkeit with the air line coupling of a coupling head type AK 69e.

In the solution according to the invention in the region of the large coupling claw of the coupling head projecting in the direction of the coupling plane first Stator and arranged in the region of the small coupling claw of the coupling head, a second, complementary to the first Anrmungsorgan trained second Stroke. It is conceivable in this case to design the first rigidating member as a coupling horn projecting in the direction of the coupling plane and the second rigidating member as a coupling pocket formed on the coupling head. The first executed in the form of a coupling horn Rigidation device is designed to be received when coupling the coupling head with the coupling head of a matching counter-coupling of the running in the form of a clutch pocket second Festrmachungsorgan of the counter-coupling head, while designed in the form of a clutch pocket second Longer is formed as Clutch horn trained first Stator of the coupling head of the counter-coupling record. Of course, however, other embodiments for the first and second Ripening come into question.

It is essential that at least when coupling the coupling head with the coupling head of a counter-coupling of the same type are arranged on the coupling head Festrmachungsorgane are formed, respectively form an engagement with a corresponding Lugernungsorgan of the counter-coupling head.

In order to achieve that, when forming a mechanical connection between the coupling head and the coupling head of a counter-coupling, the coupling part of the line coupling arranged on the coupling head is automatically moved into the second, advanced position is advanced relative to the coupling head, a lever mechanism is provided in the inventive solution, said lever mechanism can be actuated by the formation of an engagement of the second Stroke of the coupling head with a corresponding Anstalting of the counter-coupling head during the coupling process. Specifically, the lever mechanism is configured to move the coupling portion of the pipe coupling to the second (advanced) position relative to the coupling head when a respective mating coupling member of the mating coupling head is received by the second rigidating member.

A coupling head, which is equipped with such, cooperating with the coupling part of the pipe coupling lever mechanism can be coupled with a matching counter-coupling head, wherein the coupling process automatically the coupling parts of the arranged to be coupled to the coupling heads line couplings automatically moved into the second detachable position. Thus, since the front end portions of the respective coupling parts are in common point of intersection of the vertical coupling plane and the vertical longitudinal sectional plane of the coupling heads, these abut each other relatively aligned, which allows the automatic coupling of the line couplings.

If, however, a coupling head, which is equipped with a lever mechanism according to the invention with a coupling head, for example, a counter coupling type AK 69e is to be considered, on the one hand that a coupling head type AK 69e is not equipped with a corresponding lever mechanism, and on the other hand, that such a coupling head has no rigidification organs or the like, which form an engagement with the rigidification organs of the solution according to the invention during the coupling process and thus can actuate the lever mechanism. Accordingly, when coupling the coupling head with a coupling head of a counter coupling of the type AK 69e, the coupling part of the coupling head arranged on the pipe coupling is advanced by a different mechanism from the lever mechanism in the second, detachable position.

In detail, in a development of the solution according to the invention, an operating lever connected to the coupling part is provided for manual ancestor of the coupling part of the line coupling in the second, in the direction of the coupling plane advanced position.

Preferably, it is provided that in the coupling head according to the present invention, the line coupling is arranged in a plane below the coupling head and on the line height of the pneumatic brake lines or supply lines of a coupling head of a central buffer coupling type AK 69e. This allows a direct coupling of the pipe coupling arranged on the coupling head with the pneumatic brake line (s) and / or supply line (s) of the counter coupling head type AK 69e.

In a preferred realization of the coupling head according to the invention, the lever mechanism provided for the automatic ancestor of the coupling part has a first horizontally rotatable lever element which, when coupling the coupling head to the coupling head of a counter-coupling, and in particular by forming an engagement between the second Anstaltungsorgan of the coupling head and a correspondingly complementary component of the counter-coupling head is pivotable about an axis of rotation in a horizontal plane. In addition, an at least substantially vertically extending shaft is preferably provided, which is connected to the first lever element and defines the axis of rotation of the pivotable in a horizontal plane first lever member. In addition, preferably, a second, pivotable in a horizontal plane lever element is further provided, which is connected to the coupling part of the line coupling on the one hand and the shaft on the other hand, that upon pivoting of the first lever element, the resulting rotational movement is transmitted via the shaft to the second lever element, consequently the coupling part of the line coupling is driven in the direction of the coupling plane.

The second lever element may be formed as a pivoting lever with a first lever arm and a second lever arm angled to the first lever arm, wherein the vertical pivot axis of the lever member passes through the connecting portion between the first and second lever arms. It is conceivable here that the first lever arm of the pivot lever is connected via a force transmission element with the shaft, wherein the free end portion of the first lever arm in a horizontal plane pivoted at a first end portion of the power transmission element and the second end portion of the power transmission element in a horizontal plane pivotally connected to a the shaft connected lever is articulated. The free end region of the second lever arm should in this case be pivoted in the horizontal plane on the line coupling.

Of course, other embodiments come for the lever mechanism in question.

The support member may be releasably secured, for example by means of a screw on the coupling head. On the other hand, it is of course also conceivable to fasten the carrier element to the coupling head by means of a welded joint, etc.

An automatic central buffer coupling 100 for track-guided vehicles, in particular rail vehicles, will now be described in more detail by way of example with reference to the illustrations in the attached drawings, wherein the central buffer coupling 100 has a coupling head 1 according to an embodiment of the present invention.

In the accompanying drawings, identical or equivalent components of the central buffer coupling 100 are provided with the same reference numerals. Identical or equivalent components of a mating coupling 100 'coupled to the central buffer coupling 100 are likewise provided with the same reference numerals, these reference numerals however, they are differentiated by an apostrophe. From a description of identical or equivalent components of the coupled to the central buffer coupling 100 counter-coupling 100 'is to avoid repetition omitted.

In the illustrated embodiments of the central buffer coupling 100, a coupling head 1 is disposed at the front end portion of a coupling shaft 2. The coupling shaft 2 has an articulation 3 on its carriage-box-side end region in order to articulate the central buffer coupling 100 on the end face of a vehicle body (not shown) via a stabilizing joint that preferably acts on all sides.

The coupling head 1 itself is provided with a Willison contour and therefore has two rigid coupling claws, namely a Zugklaue 4 (hereinafter "large clutch claw" called) and a buffer claw 5 (hereinafter "small clutch claw" called).

The construction of the coupling head with the Willison profile is based on the construction of coupling types of the type Willison / SA-3, wherein in the coupling head 1 according to the invention also corresponding cam parts 6 are used, as a result, well-tried and known coupling components are used for mechanical coupling. In particular, the coupling head 1 is mechanically coupled not only with a matching mating coupling head 1 ', but also with a coupling head of a central buffer coupling type AK 69e and with the known types of coupling type Willison / SA-3 and coupling heads of central buffer couplings type FT-Transpact.

As shown, extending from the large coupling claw 4 in the direction of the coupling plane T, a first Anstearing element 8 in the form of a projecting in the direction of the coupling plane T front coupling horn. On the opposite side of the coupling half, a wing 10 is provided, in which a clutch pocket 9 is formed as a second rigidi. The trained as a coupling horn first Erstarmachungsorgan 8 is of such size and shape that it is easily received by the clutch pocket 9 'of an opposite, similar coupling head 1'. The advantage of the first and second Festrmachungsorgane 8, 9 is in a central buffer coupling with rigid coupling claws 4, 5 in their buckling preventing effect.

Below the coupling head 1 is a line coupling 20; 220; 320 arranged. As will be described in detail below, the line coupling 20; 220; 320 designed such that it is automatically movable in the coupling process of the coupling head 1 with a matching counter-coupling head 1 'from a first, retracted position in a second, in the direction of the coupling plane T advanced position relative to the coupling head 1. The line coupling 20; 220; 320 is formed and arranged on the coupling head 1, that the front end portion of the line coupling 20; 220; 320 belonging coupling part 21; 21a, 21b in the second (advanced) position of the line coupling 20; 220; 320 in the intersection of the vertical coupling plane T and the vertical longitudinal sectional plane L of the coupling head 1 is located. This allows automatic coupling of the line couplings 20, 20 '; 220, 20 '; 320, 20 'when the coupling head 1 is coupled with a matching mating coupling head 1', since then the respective front end portions of the coupling parts 21; 21a, 21b; 21 'of the line coupling 20; 220; 320 of the coupling head 1 on the one hand and the line coupling 20 'of the counter-coupling head 1' on the other hand axially aligned with each other abut.

As already explained, in the illustrated embodiment, the line coupling 20; 220; 320 arranged below the coupling head 1. In detail, in the illustrated embodiment, the line coupling 20; 220; 320 by means of a support member 24 so attached to the coupling head 1, that the line coupling 20; 220; 320 is movable relative to the carrier element 24 in the longitudinal direction of the line plane between the first, retracted position and the second, advanced position. The support member 24 is rigidly connected in the illustrated embodiment via a threaded connection with the coupling head 1. For this purpose, corresponding bores 16 are provided for receiving screws in the carrier element 24, wherein the screws received in the bores 16 engage in corresponding threaded bores 13 provided on the coupling head 1. Instead of a screw connection, it is of course also conceivable to fasten the carrier element 24 via a welded construction or otherwise to the coupling head 1.

In order to achieve that during the coupling process of the coupling head 1 with a matching counter-coupling head 1 'automatically the line coupling 20; 220; 320 of its first, retracted position is displaced in its second, advanced position relative to the support member 24 fixedly attached to the coupling head 1, a lever mechanism is used, the structure and operation is described below.

In detail and as it is the representation example in Fig. 1 . Fig. 8 . Fig. 9 . Fig. 10 or Fig. 11 can be removed, the lever mechanism has a first lever member 30 which is pivotally received in the region of the small coupling claw 5 of the Willison profile in the form of a clutch pocket second Stirringungsorgan 9 about a rotational axis in a horizontal plane. When coupling the coupling head 1 with a matching counter-coupling head 1 'is by inserting the trained as a coupling horn first Stroke device 8' of the mating coupling head 1 'in the form of a clutch bag second Stroke device 9 of the coupling head 1 within the clutch pocket 9 in a horizontal plane rotatably mounted first lever member 30 pivots.

As it is in particular the representation in Fig. 8 can be removed, the first lever member 30 is connected to a substantially vertically extending shaft 31, said shaft 31 defines the vertical axis of rotation of the first lever member 30. When the first lever member 30 is pivoted in sliding the coupling horn 8 'of the counter-coupling head 1' in the coupling pocket 9 of the coupling head 1 in a horizontal plane, the torque is transmitted to a second lever member 32 via the shaft 31.

As described in detail below with particular reference to the illustration in, for example, FIG Fig. 5 . Fig. 7 or Fig. 11 is described, the second lever element is pivotable in the horizontal plane and on the one hand with the line coupling 20; 220; 320 and on the other hand connected to the shaft 31 such that upon pivoting of the first lever member 30, the resulting rotational movement is transmitted via the shaft 31 to the second lever member 32, consequently the line coupling 20; 220; 320 is moved from its first, retracted position in the direction of the coupling plane T to its second, advanced position.

In detail, and as for example the representation in Fig. 5 or Fig. 11 can be removed, in the illustrated embodiment, the second lever member 32 is formed as a pivotable in a horizontal plane pivot lever, which has a first lever arm 32a and a first lever arm 32a angled second lever arm 32b, wherein the vertical pivot axis of the second lever member 32 passes through the connecting portion between the first and the second lever arm 32a, 32b. The first lever arm 32a of the pivoting lever 32 is connected via a power transmission element 33, which - as in Fig. 5 or Fig. 11 shown - may be formed, for example, as a rod connected to the shaft 31. The free end region of the first lever arm 32a of the second lever element 32 designed as a pivoting lever is pivoted in a horizontal plane on a first end region of the force transmission element 33 and the second end region of the force transmission element 33 is pivoted on a lever 34 connected to the shaft 31 in a horizontal plane.

On the other hand, in the illustrated embodiment, the free end portion of the second lever arm 32b of the second lever member 32 formed as a pivot lever in a horizontal plane is pivotable on the line coupling 20; 220; 320 hinged. By such a lever mechanism can be used in the mechanical coupling process with a matching counter-coupling head 101 'on the first lever member 30 rotational movement to be used, the line coupling 20; 220; 320 to advance relative to the coupling head 1 in the direction of the coupling plane T.

As for example the representation in Fig. 5 . Fig. 7 and Fig. 11 can be removed, in this embodiment, the shaft 31 connected to the lever 34, on which the second end portion of the power transmission element 33 is pivoted in the horizontal plane, designed as a pivot lever with an additional lever arm 35, which via a tension spring 36 with the on the Coupling head 1 fixed support member 24 is connected. The tension spring 36 thereby counteracts a coupling action of the coupling head 1 with a matching counter-coupling head 1 'via the first lever member 30 transmitted to the shaft 31 torque. This has the consequence that when uncoupling, ie when disconnecting the coupling head 1 of a matching counter-coupling head 1 ', due to the torque transmitted to the shaft 31 by means of the tension spring 36, the lever mechanism returns to its original position, in which the line coupling 20; 220; 320 is in its first, retracted position. Accordingly, the coupling head 1 of the present invention is designed so that not only a mechanical connection between the coupling heads 1, 1 'is realized in the coupling process with a matching counter-coupling head 1', but also the line couplings 20, 20 '; 220, 20 '; 320, 20 ', and thus in particular the pneumatic brake lines and / or supply lines are automatically coupled together. The special construction of the coupling head 1 also allows the coupling head 1 to be coupled to the mating coupling head of a type AK 69e central buffer coupling. As already mentioned in the introduction to the description, central buffer couplings of the type AK 69e are currently still in larger quantities, especially for iron ore transports in use.

Since a coupling head of a type AK 69e center buffer coupling is not equipped with a mechanism comparable to the above-described lever mechanism, additional measures are provided in the coupling head 1 according to the present invention for coupling the air line coupling of the coupling coupling head of a type AK 69e center buffer coupling Counter-coupling head in the direction of the coupling plane T automatically advance.

In detail, it is provided that the coupling head 1 - as for example the representations in the FIGS. 1 to 3 . 9 and 10 can be removed - in the region of the small coupling claw 5 has a projecting in the direction of the coupling plane T area 7, which is hereinafter referred to as "horn". This horn 7 serves to slide and vertically align the mating coupling head of an AK 69e center buffer coupling when the mating coupling head is coupled to the coupling head 1 of the present invention. When coupling operation of the coupling head 1 according to the invention with the mating coupling head of a central buffer coupling type AK 69e the horn 7 serves simultaneously for actuating a provided on the counter-coupling head pedal, with which the mating coupling head belonging air line coupling is driven in the direction of the coupling plane T. By providing the in the direction of the coupling plane T projecting horn 7 can thus be effected during coupling of the coupling head 1 with the counter-coupling head of a central buffer coupling type AK 69e that the coupling line head the air line coupling of the counter-coupling head is driven in the direction of the coupling plane T.

Since usually coupling heads of a central buffer coupling type AK 69e are not equipped with appropriate Festrmachungsorganen that retract in the coupling process with the coupling head 1 of the present invention in the form of a clutch bag second Festrmachungsorgan 9, the mechanical coupling of the coupling head 1 according to the invention with the mating coupling head of a central buffer coupling Type AK 69e does not automatically activate the lever mechanism and the line coupling 20; 220; 320 of the coupling head 1 according to the invention in the second position in the direction of the coupling plane T advanced.

Nevertheless, an ancestor of the line coupling 20; 220; To be able to bring 320 in the second position is - as shown in particular in the Fig. 5 . Fig. 7 and Fig. 11 can be removed - one with the line coupling 20; 220; 320 connected operating lever 22 is provided, which is pivotable in the horizontal plane for manual ancestor of the line coupling 20; 220; 320 in the second, in the direction of the coupling plane T advanced position.

In the solution according to the invention, in particular, it is provided that the line coupling 20; 220; 320 is arranged on the coupling head 1 such that the coupling part 21; 21a, 21b of the line coupling 20; 220; 320 is at the pipe height of the air line coupling of a coupling head type AK 69e. This allows a direct coupling of the coupling head 20 arranged on the coupling head 1 according to the invention; 220; 320 with the air line coupling of the counter-coupling head of a central buffer coupling type AK 69e. For this purpose, the line coupling 20; 220; 320 by hand via the actuating lever 22 to the already advanced air line coupling of the counter-coupling head of the central buffer coupling type AK 69e coupled and secured with a locking pin 23 in the coupled position (see. Fig. 8 ).

This special design of the coupling head 1 according to the invention eliminates the need for an additional device in the form of a mixed air clutch, etc., to be used for coupling the air line couplings. Another advantage is the ease of use. The difficult engagement of a mixed air clutch in the below the central buffer coupling arranged and thus difficult to access air line at a central buffer coupling type AK 69e is eliminated.

In the following, with particular reference to the illustration in FIG Fig. 4 and Fig. 12 the structure of the line coupling 20 used in the inventive solution; 220; 320 described.

The line coupling 20; 220; 320, which is preferably arranged below the coupling head 1 at the line height of the pneumatic brake lines and / or supply lines of a central buffer coupling type AK 69e, in the illustrated embodiment by means of the already mentioned support member 24 in the longitudinal direction of the line plane relative to the support member 24 movable on Coupling head 1 attached. In detail, the line coupling 20; 220; 320, a carriage member 25 movable relative to the support member 24 in the longitudinal direction of the guide rail and a coupling member 21 resiliently supported in the carriage member 25; 21a, 21b, in the second advanced position of the line coupling 20; 220; 320, the front end portion of the coupling part 21; 21a, 21b is in the management level. As already stated, the ancestor of the line coupling takes place automatically in the second position when the coupling head 1 is coupled with a matching counter-coupling head 1 '.

For this purpose, a lever mechanism is used, which is actuated via the insertion movement of the coupling horn 8 'of the counter-coupling head 1' in the clutch pocket 9 of the coupling head 1 (see, in particular, the illustration in FIG Fig. 6 ).

Specifically, during the insertion movement, a first lever element 30 pivotably mounted in the coupling pocket 9 of the coupling head 1 in a horizontal plane is pivoted, with the resulting rotational movement via the shaft 31 to the pivot lever 32 pivotably mounted on the support element 24 in a horizontal plane and from there as linear movement on the longitudinal direction of the line plane relative to the carrier element 24 movable line coupling 20; 220; 320 is transmitted. On the other hand, the line coupling 20; 220; 320 are also moved forward manually by operating the operating lever 22 in the second position.

The resiliently mounted in the carriage member 25 coupling part 21; 21a, 21b can - as the presentation in Fig. 4 for the embodiment as the air coupling part is removable - a coupling body 26 and a clutch body 26 held by the coupling body 26 and preferably releasably secured air coupling insert 27, wherein the air coupling insert 27 at its front, the coupling plane T end facing a mouthpiece seal 28; 28a, 28b.

In one embodiment, as shown in FIG Fig. 10 is removable for the coupling body 26 - 27 may be provided in the coupling body 26 instead of the air coupling insert 27, an electrical contact insert, which has electrical contacts 46.

In particular, it is provided in the illustrated embodiments that the air coupling insert 27 is designed as a tubular member which the mouthpiece seal 28; 28a, 28b carries.
