Description

The present invention relates to a device for adapting a coupling head of a central buffer coupling with a joint half of a joint arrangement. In particular, the device according to the invention is designed to mechanically connect the coupling head of a central buffer coupling of the Willison type with a joint half of a joint arrangement.

In rail vehicle technology, central buffer couplings are used to connect two independent vehicles or trains to one train. The task of a central buffer coupling is solely to prevent relative movements along the vehicle longitudinal axis between the coupled car bodies. A transfer of forces in the other direction or a restriction of other degrees of freedom is not desirable. A central buffer coupling is a connection between two vehicles which can be detached and reconnected without much effort. Vehicles that are connected via center buffer couplings are operable in both the coupled and uncoupled states. Central buffer couplings are generally carried out in a standardized manner so that vehicles which use the same coupling system can be coupled with each other as desired.

In contrast, in rail vehicle engineering joint arrangements have the task of binding car bodies to each other while allowing defined movements between the car bodies, but also to restrict certain degrees of freedom. Two car bodies connected via a joint arrangement together form a vehicle. The release of two connected by a hinge assembly car bodies is possible only with the aid of suitable tools and not provided in normal operation of the vehicle. Joint arrangements take over the coupling of two car bodies in the vehicle longitudinal direction often other functions, such. B. supporting a part of the weight or the steering of the car body. Thus, an operation of the separate car bodies is not possible; the separated car bodies can not be considered as separate vehicles.

A joint arrangement has a first (half) fixed to the base of a first car body (fixed) half-joint and a second fixedly connected to the base of a second car body (fixed) hinge half, said two hinge halves are hinged together via a common, vertically extending hinge pin. In general, the joint halves are designed in the form of bearing blocks, which are connectable for example via a flange with the base of the associated car body.
Different solutions for adapting couplings of different types are known from the prior art. For example, the document relates EP 2 384 948 A1 a transition coupling for releasably connecting a coupling head of a Scharfenberg® automatic central buffer coupling with the draw hook of a screw coupling.
Next is from the document EP 2 529 994 A1 a Rangierkupplung known for track-guided vehicles, said Rangierkupplung has a coupling head changer to load coupler heads of different types or different types in a defined by the Rangierkupplung vertical coupling plane and in particular einwenken. In this way, the maneuvering coupling can optionally be connected to a type 10, type 35, type 330, type 430, type 55 or type 140 coupling head.

The document EP 2 261 098 A1 relates to a transition coupling for rail vehicles for coupling an automatic central buffer coupling of the Willison type with a manually operable screw coupling, wherein the automatic center buffer coupling in the region of a laterally enclosed by rigid coupling claw coupling jaw has a component for tensile force transmission, which at its coupling-side end portion in a towing hook with a having self-acting central buffer coupling to be connected screw coupling attachable drawbar. Although approaches are already known from the prior art, with which a mixed coupling between an automatic central buffer coupling and a screw coupling or AAR coupling is possible, missing solutions that allow adapting a central buffer coupling with the hinge half of a hinge assembly. In particular, the transition couplings known from the prior art for mixed coupling between central buffer couplings and screw couplings or AAR couplings are structurally and functionally unsuitable for also enabling the adaptation of a coupling head of a central buffer coupling to a joint half of a joint assembly. This is due in particular to the fact that the joint halves of a joint arrangement - in contrast to the coupling heads of a central buffer coupling - are in principle not intended to be detachable without great effort and again to provide detachable connection between two vehicles or car bodies.

Accordingly, the present invention has for its object to provide a device that allows a transition between the mechanical joint between the joint half of a hinge assembly and the coupling head of a central buffer coupling. In particular, a solution should be given, with which the individual bodies of a multi-membered and connected via a joint assembly, in particular track-guided vehicle to mechanically couple with a vehicle which is equipped with a central buffer coupling, in particular a central buffer coupling type SA-3. In particular, the solution according to the invention should be suitable for being able to transmit both tensile and compressive forces.

Accordingly, in particular a device for adapting a coupling head of a central buffer coupling is proposed with a hinged to a base of a vehicle or fixable joint half of a hinge assembly, wherein the device has an adapter part and at least one transition part. With regard to the coupling head of the central buffer coupling, the adapter part of the device according to the invention is at least partially designed to be complementary in such a way that it can be detachably connected to the coupling head.

The at least one transition part serves for (mechanically) connecting the adapter part to the joint half of the joint arrangement. For this purpose, it is provided in the inventive solution that the adapter part has at least one bearing arrangement for the articulation of a coupling head end region of the at least one transition part. The at least one bearing arrangement has, for example, a bearing eye into which a vertically extending bolt can be received, via which the coupling head-side end region of the at least one transition part can be linked to the adapter part in the horizontal plane. On the other hand, in the solution according to the invention, the joint-half-side end region of the at least one transition part is assigned at least one receptacle for connecting the transition part to the joint half.

This the joint half-side end portion of the at least one transition part associated receptacle may be formed, for example, as a bearing to connect the joint half-side end portion of the transition part hinged to the hinge half, in particular such that the transition part is pivotable relative to the bearing half in a horizontal plane. As an alternative to this, it is conceivable to form the receptacle associated with the hinge half-side end region of the at least one transitional part for detachable connection, in particular releasable fixing, of the transitional part to the joint half. Such a releasable connection can be realized for example via a screw connection. Of course, however, other embodiments are conceivable in this context.

In the solution according to the invention, the at least one transitional part not only has the task of mechanically connecting the coupling head of the central buffer coupling with the joint half, but also the further task of bridging an optionally existing vertical offset between the coupling head of the central buffer coupling and the joint half.

With regard to the coupling head of the central buffer coupling, the adapter part of the device according to the invention is at least partially designed to be complementary in such a way that it can be detachably connected to the coupling head. In particular, the adapter part is designed so that it can be received by the coupling members of the coupling head.

As coupling head different types or types in question, such as a coupling head of the Willison type, in particular a coupling head type SA-3, or even a coupling head, for example of the type Scharfenberg®.

In a preferred embodiment of the solution according to the invention, it is provided that at least two transition parts designed separately from one another are provided. The coupling head-side end regions of the two separately executed transition parts are in this case via the at least one bearing arrangement in such a way connected to the adapter part, that they are pivotable relative to the adapter part about a common vertical pivot axis. By providing at least two separately executed transition parts, the weight of the individual transition parts can be kept as low as possible, which facilitates the assembly and disassembly of the transition parts accordingly.

The solution according to the invention is particularly characterized in that the coupling head of the central buffer coupling can be mechanically connected to the vehicle body equipped with a joint arrangement, without it being necessary for this purpose to remove the components belonging to the joint arrangement and connected to the vehicle body. In particular, the disassembly of the joint half is eliminated, since only the vertically extending central longitudinal axis of the car body cutting hinge pin of the joint assembly must be removed.

In an advantageous development of the last-mentioned embodiment, in which two transition parts designed separately from one another are provided, it is provided that the joint-half-side end regions of the two separately executed transition parts are connected to the joint half via separate receivers. In an advantageous manner, the two separate mutually executed receptacles with respect to the central longitudinal axis of the car body (and thus with regard to the pivot axis defined by the vertically extending hinge pin of the joint assembly) are arranged decentrally. The recordings are arranged in particular mirror-symmetrically with respect to the central longitudinal axis.
