Abstract

The coupling (1) has a retainer retaining a tow hook (50) of a clutch. A height adjustment device includes a towing eye (14) connected with a clutch housing (2). The towing eye is arranged relative to the retainer such that an interference of the tow hook in the retainer and in the towing eye is formed while inserting the coupling into a plane hole of the tow hook in a common process. The towing eye is connected with the housing by mechanics, so that the towing eye is movable relative to a pull bow (8) in a longitudinal direction (L) of the coupling for height adjustment of the coupling. The transition coupling is releasably connected with an automatic central buffer coupling such as Scharfenberg(RTM: fully automatic coupler) type central buffer coupling.

Description

description

The invention relates to a transition coupling according to the preamble of the independent claim 1.

Accordingly, the invention particularly relates to a transitional coupling for adapting couplings of different types, wherein the transitional coupling comprises a first connecting means for releasably connecting the transitional coupling with a first clutch, a second connecting means for releasably connecting the transitional coupling with the towing hook of a second clutch and a coupling support for connecting the first connecting device with the second connecting device, wherein the second connecting device comprises a clamping yoke, wherein the clamping yoke has a first and a second carrier, which are connected to a tie bolt such that a receptacle is formed for receiving the towing hook of the second coupling.

For example, the invention relates to a transition coupling for mixed coupling between an automatic central buffer coupling and a screw coupling, wherein the first connection portion of the transition coupling may be formed as a dome closure for releasably connecting the transition coupling with the coupling head of an automatic central buffer coupling, and wherein the second connection region of the transition coupling as a in the tow hook of a screw coupling usable coupling bracket may be formed for releasably connecting the transitional coupling with the coupling head of a screw coupling.

The term "connection area" as used herein generally means an interface between the coupling support of the transition coupling on the one hand and the coupling to be connected to the transition coupling on the other hand. The connection region may be formed, for example, as a dome closure or have a dome closure for releasably connecting the transition coupling with the coupling head of an automatic central buffer coupling. On the other hand, it is conceivable that the connecting portion has a coupling bracket, which is insertable in the towing hook of a screw coupling. Of course, come for the connection area but other embodiments in question.

A generic transition coupling is generally known from rail vehicle technology and is used to connect rail vehicles that are equipped with different coupling systems (eg Scharfenberg ^® coupling on towing hook). The placement of the transition coupling, for example, on the tow hook is done manually in the rule, while the coupling process can take place automatically with the central buffer coupling.

A conventional transition coupling for mixed coupling between an automatic central buffer coupling and, for example, a screw coupling usually has a clutch carrier formed at least partially as a housing, in which a dome closure can be accommodated as the first connection device for mechanically connecting the transitional clutch to an in the coupling head of an automatic central buffer coupling provided dome closure. In the coupled state then lies on the end face of the transition coupling on the end face of the coupling head of the automatic central buffer coupling.

At the end opposite the end face of the transition coupling may be provided as a second connection means a coupling bracket, which is for example in the tow hook of a screw can be received and therefore can ensure a mechanical connection of the transition coupling with the screw coupling.

In operation, tensile and compressive forces are introduced from the towing hook of the screw coupling into the second connecting device of the transitional coupling designed as a coupling bracket. The pressure forces introduced into the coupling yoke or second connecting device are conducted via the coupling carrier to the end face of the transitional coupling and transmitted from there to the end face of the coupling head of the automatic central buffer coupling that is mechanically connected to the transition coupling.

On the other hand, pulling forces are transmitted via the first connecting means, such as the automatic central buffer coupling. The dome closures may, for example, have a centerpiece rotatably mounted relative to the clutch carrier via a main bolt, with a coupling eye articulated thereto. In this case, there is a tensile force transmission via the respective coupling eyes, which engage in the corresponding frogs.

It should be noted that the present invention is by no means limited to a transitional coupling designed to connect an automatic central buffer coupling to a screw coupling. Rather, the invention generally relates to a transitional coupling for adapting couplings of different types, wherein the transitional coupling comprises a connecting device which is compatible with a coupling of a first type and adapted to form a detachable connection with the coupling of the first type, and wherein the transition coupling further second connecting device, which is compatible with a coupling of a second type having a towing hook and designed to form a releasable connection with the coupling of the second type.

A known from the prior art transition coupling of the type mentioned is in Fig. 1 in a side view and in Fig. 2 shown in a perspective view. The transition coupling 101 is placed in the illustrated embodiment on the towing hook 50 of a screw coupling to be adapted. For this purpose, the transition coupling 101 is provided at its rear end on both sides with parallel spaced apart and identically designed carriers 103, 103 ', which are connected at the free ends by a bolt 104 which holds the transition clutch 101 in the mouth of the towing hook 50 , On both sides of the conventional transition coupling 101, an angle lever 105 is arranged. A first link 105a of the angle lever 105 is designed to be telescopically displaceable. Such as in Fig. 1 1, the first link 105 a, which is held in the extended position by a compression spring 109, is articulated to the transition coupling 101. A second link 105b of the angle lever 105 is formed as a rigid arm. The first and second links 105a, 105b are interconnected at their respective free ends by a common yoke 107. Through the yoke 107, an adjusting nut 106 is guided centrally, which carries for supporting on the nose of the towing hook 50 on the bottom cap-shaped recessed web 108. The links 105a, 105b on both sides of the transition coupling 101 are connected by a common axis 110 and with each other, the axis 110 serves as a contact surface on the end face of the towing hook 50, so that by adjusting the web 108, the vertical angular position of the transition clutch 101 to the bolt 104 and thus the center position of the transition coupling 101 is adjustable.

By providing the angle lever 105, a height centering can be realized in the known from the prior art transition clutch 101. However, the manual handling, and in particular the manual insertion of the transition coupling 101 in the interface between the couplings to be adapted, such as in the draw hook 50 of a screw coupling, difficult because it is not possible for an operator, on the one hand the weight of the transition coupling 101 to and, on the other hand, correctly attach the height-centering device to the hitch 50.

Based on this problem, the invention has for its object to provide a transition coupling of the type mentioned above with a device for Höhenzentrierung, in spite of the device for leveling the manual handling of the transitional coupling is simplified.

This object is solved by the subject matter of independent claim 1.

In particular, therefore, the transition coupling according to the invention has a device for height centering, which comprises a connected to the clutch housing of the transition coupling drawbar. This drawbar eye is arranged and designed relative to the drawbar so that when inserting the transition coupling in the mouth of the tow hook in a common operation an engagement of the tow hook is formed with both the drawbar and with the drawbar eye.

The achievable with the inventive solution advantages are obvious. Characterized in that for height adjustment of the transitional coupling a connected to the clutch carrier of the transition coupling drawbar is provided which is designed and designed with respect to the drawbar to receive the nose of the tow hook when the drawbar is inserted into the tow hook is for positioning and mounting of the transitional coupling at the second coupling to be adapted only a single step necessary. The clamping yoke of the transitional coupling and provided for Höhenzentrierung drawbar are arranged and formed relative to each other such that upon insertion of the transitional coupling in the mouth of the towing hook of the drawbar forms engagement with the tow hook and at the same time the nose of the tow hook is received by the towing eye. Accordingly, it is also possible for a single person with relatively little effort to install the transition coupling, as provided for Höhenzinierung drawbar automatically absorbs the nose of the tow hook as soon as the drawbar of the transitional coupling is hooked into the mouth of the towing hook.

The solution according to the invention is further distinguished by the simple construction of the device for height centering, so that in comparison to a conventional transition coupling (cf., for example, the in Fig. 1 or. Fig. 2 shown transition coupling) fewer components are required, resulting in a weight reduction of the transition coupling.

Advantageous developments of the solution according to the invention are specified in the dependent claims.

In order to achieve that in a common operation when inserting the transition coupling into the mouth of the towing hook of the towing hook forms an engagement with the drawbar, while the nose of the tow hook is received by the towing eye, it is particularly conceivable that the towing eye designed and is aligned relative to the trained with the yoke receptacle that overlap the parallel projection of the drawbar eye and the parallel projection of the recording on a horizontal plane of projection at least partially. For example, it is provided in an implementation of the solution according to the invention that the second connecting device has two preferably parallel support with a horizontally extending tie bolt connecting the supports to form the tie bar, wherein the tow hook of the second coupling can be received in the region between the two parallel supports. In this realization, the drawbar eye should preferably be provided on the upper side of the coupling support and be aligned substantially axially at least partially with the area between the two supports. This facilitates the handling of the transition coupling, since the transition coupling is usually inserted from above into the towing hook of a coupling to be adapted. Of course, other realizations are conceivable.

In order to achieve that in an easy to implement, but effective way, the height of the transition coupling transition can be adjusted, it is provided in a preferred embodiment that the towing eye is connected via a special mechanism with the clutch carrier of the transitional coupling that the height centering of the transitional coupling the towing eye in the longitudinal direction of the transitional coupling is movable relative to the clamping yoke. This is a particularly easy to implement, yet effective solution to implement the height centering of the transition coupling. By the drawbar eye is moved in the longitudinal direction of the transitional coupling relative to the drawbar in the direction of the first connecting portion, a tensile force can be exerted on the nose of the tow hook received in the drawbar over the drawbar eye, which acts on the transition coupling torque and thus a vertical pivoting of Transition coupling has relative to the tow hook to the draw bolt of the drawbar result.

In an advantageous development of the latter embodiment, the mechanism with which the towing eye is movable relative to the drawbar in the longitudinal direction of the transitional coupling, a first and a second stop in order to limit the longitudinal movement of the towing eye can. In this way it is ensured that the transition coupling is pivotable relative to the towing hook only within a pre-definable vertical angle range. The first and second stops are to be designed in such a way that the permissible swivel range is selected so that driving dynamic movements are permitted during driving.

In a preferred development of the last-mentioned embodiments, the mechanism by means of which the drawbar eye is connected to the coupling support of the transition coupling has at least one spring element in order to bias the drawbar eye in the direction of the second connection device. Preferably, the amount of the bias exerted by the spring element is in advance adjustable. By providing at least one spring element, the driving dynamic movements occurring during driving can be damped.

In a particularly preferred realization of the transitional coupling, the mechanism, via which the towing eye is connected to the coupling support, a movable in the longitudinal direction of the transition coupling relative to the drawbar drawbar or the like, wherein the drawbar is fixed to the end region of the drawbar, which is the second Facing connection device. In this case, it is also conceivable that a carrier which is preferably detachably connected to the clutch carrier is provided, which has an opening through which the pull rod is guided. Between the carrier and the end of the connecting rod facing the first connecting device, the already mentioned at least one spring element is preferably arranged in order to bias the drawbar eye in the direction of the first connecting device.

Particularly preferably, the carrier is releasably connected to the clutch housing, which allows, for example, the retrofitting of a transition coupling with a device for leveling.

The carrier is preferably connected to the coupling housing on the upper side of the coupling housing. It is conceivable, of course, but also that the carrier is connected to the side of the coupling housing with the coupling housing.

In the following, embodiments of the invention with reference to the representations in the FIGS. 3 to 7 described in more detail.

In the FIGS. 1 and 2 a transition coupling 101 known from the prior art is shown, which has an angle lever 105 for height centering, which is fastened via a yoke 107 on the nose of a towing hook 50. The angle lever 105 is secured laterally with the housing 102 of the transitional coupling 101 and ensures the centering of the transitional coupling 101th

As already stated, a disadvantage in the conventional in the FIGS. 1 and 2 can be seen in that due to the relatively complicated structure of the device for leveling in the form of an angle lever 105, the assembly of the transitional coupling 101 on the towing hook 50 of a coupling to be adapted relatively difficult to execute. In particular, it is not possible to mount the transition coupling 101 by a person alone on the towing hook 50 of a coupling to be adapted, since not at the same time held by a person, the transition coupling 101 and the device for leveling can be correctly attached to the towing hook 50.

To take care of these disadvantages, a transition coupling 1 is proposed according to the invention, as with reference to the representations in the FIGS. 3 to 7 will be described in more detail below with reference to exemplary embodiments. In detail shows Fig. 3 a first embodiment of the transition coupling 1 according to the invention in a side view, while in Fig. 4 the transitional coupling 1 according to the first embodiment is shown in a perspective view.

The in the Figures 3 and 4 illustrated embodiment of the transition coupling 1 according to the invention consists of a coupling housing 2, which at least partially receives the coupling members of the transitional coupling 1. Specifically, a dome closure 5 is received in the clutch housing 2 as the first connection means, which serves for releasably connecting the transitional coupling 1 with the coupling head of an automatic central buffer coupling (not shown).

In the in the Figures 3 and 4 illustrated embodiment, the transition coupling 1 is designed to couple with an automatic central buffer coupling of the type Scharfen-berg ^®.

Accordingly, in the illustrated first embodiment, the dome closure 5 accommodated in the coupling housing 2 in particular has a frog which is rotatably mounted relative to the coupling housing 2 via a vertically extending main bolt 6. At the heart of a coupling eye 7 is articulated, which serves to engage in a heart of a to be coupled with the transition coupling 1 automatic central buffer coupling.

Although in the Figures 3 and 4 not explicitly shown, it is of course conceivable that the dome closure 5 in addition to the already mentioned core, which is rotatably mounted on the main pin 6 in the clutch housing 2, and on which the coupling eye 7 is hinged, also tension springs, spring bearings and a pawl rod with punch guide to allow automatic coupling and decoupling of the transition coupling 1 with an automatic central buffer coupling, for example of the type Scharfenberg ^® . Accordingly, it is preferred if the dome closure 5 accommodated in the coupling housing 2 is designed as a conventional rotary closure and is designed to be mechanically detachably connected to the coupling head of an automatic central buffer coupling.

The dome closure 5 accommodated in the coupling housing 2 serves to transmit tensile forces when the transition coupling 1 with the in the Figures 3 and 4 not explicitly shown coupling head of an automatic central buffer coupling is mechanically connected. Pressure forces, however, are transmitted via the flat end face 11 of the coupling housing 2. As for example in the representations in the Figures 3 and 4 can be removed, this has the coupling housing 2 has a profile consisting of a wide, flat edge and conical and funnel-shaped guide surfaces. This profile aligns the transitional coupling 1 with respect to a central buffer coupling to be mechanically connected to the transitional coupling 1, centers it and allows it to slide into one another even in tight bends and when displaced vertically.

As it is in particular the representation in Fig. 4 can be seen, the coupling housing 2 of the transitional coupling 1 may have an end face 11 which is integrally formed with the coupling housing 2 or formed separately to the coupling housing 2 and connected via a screw connection to the coupling housing 2. The end face 11 preferably has a funnel for receiving the coupling eye of an automatic central buffer coupling to be mechanically connected to the transition coupling 1. Adjacent to the formed in the end face 11 of the coupling housing funnel is in the in the Figures 3 and 4 illustrated transition coupling 1 further formed on the end face 11 of the coupling housing 2, a cone 12. Accordingly, the end face 11 of the transitional coupling 1 has a profile which is compatible with the profile of a coupling head of an automatic central buffer coupling.

In which the end face 11 of the coupling housing 2 opposite end portion of the transition coupling 1 is - as shown in the Figures 3 and 4 can be removed - a drawbar 8 running, which is used in the towing hook 50, for example a screw coupling for releasably connecting the transition coupling 1 with the screw coupling. For this purpose, the end face 11 of the coupling housing 2 opposite end portion of the transitional coupling 1 has a corresponding recess 13 which extends on the longitudinal axis L of the transitional coupling 1.

In the in the Figures 3 and 4 shown first embodiment of the transition coupling 1 according to the invention are at the end face 11 of the coupling housing 2 opposite end portion of the transition coupling 1 two in Longitudinal direction of the transitional coupling 1 extending parallel support 3, 3 'is provided, which are connected to each other by means of a horizontally extending tie bolt 4 to form the drawbar 8 at the end portion of the transitional coupling 1. The hitch 50 of the screw coupling is engageable with the clamping yoke 8 by - as in the Figures 3 and 4 shown - the tow hook 50 is received in the recess 13 between the two parallel beams 3, 3 '.

Of course, it is not absolutely necessary that the two carriers 3, 3 'are aligned parallel to one another. In particular, it is conceivable that these are slightly inclined to each other.

In order to achieve that the transitional clutch 1 is set for a smooth coupling in the vertical zero position and this position is maintained when coupling, the transition coupling 1 has a height centering. An essential part of this height-centering is connected to the coupling housing 2 drawbar eye 14, which - as in the Figures 3 and 4 shown - at least partially aligned with the recess 13 of the drawbar 8 and serves to accommodate at least the nose of the towing hook 50 when the towing hook 50 of the coupling to be adapted to the drawbar 8 of the transitional coupling 1 is engaged. In detail and how it in particular the representation in Fig. 4 can be removed, in the embodiment, the drawbar eye 14 is provided on the upper side of the coupling housing 2 and substantially axially aligned at least partially with the area between the two parallel beams 3, 3 ', which form the clamping yoke 8 at the end portion of the transitional coupling 1. By this measure it can be achieved that the nose of the tow hook 50 is automatically absorbed in the drawbar eye 14 of the Höhenzentrierung when the drawbar 8 of the transitional coupling 1 is inserted into the draw hook 50 of the screw to be adapted.

The representation in Fig. 3 It can be seen that in the first embodiment of the transition coupling 1 according to the invention the drawbar eye 14 is formed and aligned relative to the trained with the yoke 8 recording, that the parallel projection P1 of the drawbar eye 14 and the parallel projection P2 recording on a horizontal projection plane at least partially overlap. The overlap is in Fig. 3 designated by the reference numeral "P3".

In the in the Figures 3 and 4 illustrated embodiment, the drawbar eye 14 of the height centering is in detail such a mechanism with the coupling housing 2 of the transitional coupling 1 connected to the height of the transition coupling 1, the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the clamping yoke 8 is movable. In the illustrated embodiment, a drawbar 15 movable in the longitudinal direction L of the transitional coupling 1 relative to the clamping yoke 8 is used for this purpose, the drawbar eye 14 being fastened to the end region of the drawbar 15 facing the screw coupling. This tie rod 15 itself extends substantially parallel to the longitudinal direction L of the transitional coupling 1. The tie rod 15 together with the attached to an end portion of the tie rod 15 drawbar 8 is movable in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8. For this purpose, the pull rod 15 is guided by an opening 17 provided in a carrier 16 connected to the coupling housing 2. The carrier 16 itself is in the illustrated embodiment of the inventive βen transition coupling 1 by means of a screw 18 releasably secured to the top of the coupling housing 2. Of course, it is also conceivable that the carrier 16 is welded to the top of the coupling housing 2 or otherwise secured.

As in the Figures 3 and 4 illustrated, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 is limited relative to the drawbar 8 by means of a first stop 19.1 on the one hand and a second stop 19.2 on the other. The first stop 19.1 is provided at the end of the drawbar 15 facing the screw coupling. The second stop 19.2 is formed by a nut 20 which is screwed to the opposite end region of the tie rod 15. In detail, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8 is limited on the one hand by the fact that the first stop 19.1 abuts against the front side of the support 16. On the other hand, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 is limited by the second stop 19.2, which abuts against the facing end face of the carrier 16.

In order to achieve that in the solution according to the invention, the height centering during driving dynamic movements relative between the transitional coupling 1 and a screw coupling can compensate dampening, the height centering further comprises a spring element 21 in the form of a compression spring. In detail is in the in the Figures 3 and 4 illustrated embodiment, the spring element 21 biased between the nut 20 and the carrier 16.

By adjusting the nut 20, the pull rod 15 is displaced relative to the coupling housing 2 in the longitudinal direction L of the transitional coupling 1 together with the attached thereto drawbar eye 14 by the force exerted by the spring element on the carrier 16 compressive force. In this way, the vertical angular position of the transitional coupling 1 about the bolt 4 and thus the center position of the transitional clutch 101 can be adjusted.

The following is with reference to the representations in the FIGS. 5 to 7 a second embodiment of the transition coupling 1 according to the invention described. In detail, the second embodiment of the transition coupling 1 in the FIGS. 5a and 5b each shown in a perspective view. A side view of the transitional coupling 1 according to the second embodiment is shown in FIG Fig. 6 shown while Fig. 7 a plan view of this transitional coupling 1 shows.

The transitional coupling 1 according to the second embodiment is executed structurally and functionally similar to the first embodiment. The difference between the transitional clutch 1 according to the second embodiment and the transitional clutch according to the first embodiment is particularly seen in the fact that in the second embodiment, the position of the height adjustment with respect to the clutch housing 2 of the transitional clutch 1 is made different. Specifically, in the second embodiment, the pull rod 15 is no longer horizontal, as in the first embodiment, but slightly inclined. As before, however, the drawbar eye 14 is designed in such a way and oriented relative to the receptacle formed with the drawbar 8 that the parallel projection P1 of the drawbar eye 14 partially covers the parallel projection P2 of the recording on a horizontal projection plane, as shown in FIG Fig. 6 can be seen.

The other components of the transition coupling 1 according to the second embodiment, moreover, correspond to the components of the first embodiment, so that reference is made to avoid repetition at this point to the previous statements.

The invention is not as previously described with reference to the illustrations in FIGS FIGS. 3 to 7 described embodiments of the transition coupling limited, but results from a synopsis of all the features disclosed herein. In particular, it is conceivable that the carrier 16 is not on the top the coupling housing 2, but laterally of the coupling housing 2 with the coupling housing 2 is preferably releasably connected.

Also, other constructions for adjusting the drawbar eye 14 in question. For example, it is conceivable to provide a pivoting mechanism in order to move the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8.
