Definitions
- the invention relates to an electrical contact coupling for an automatic buffer coupling with a rail vehicle.
- the invention further relates to a central buffer coupling for a rail vehicle.
- Conventional electrical contact couplings for automatic central buffer couplings of a rail vehicle are usually arranged adjacent to a mechanical contact coupling of the central buffer coupling and have a coupling housing in which an interface unit with a plurality of connection elements is arranged.
- the Elektrotivekupp treatment also has a protective flap for covering access to the connection elements of the interface unit.
- the protective flap is connected to an actuating device for moving the protective flap between a first position in which the protective flap covers the access and a second position in which the protective flap releases the access.
- EP 1102696 B1 discloses an electrical contact coupling for an automatic central or central buffer coupling for rail vehicles.
- the electric contact clutch has a contact carrier that can be fastened to the coupling head and is longitudinally displaceable in the longitudinal direction of the central buffer coupling.
- the contact carrier has contacts for electrical connections and can be displaced from a rear, uncoupled position to a front position ready for coupling.
- the contact carrier is covered by a protective flap in the rear position and exposed in the front position when the protective flap is pivoted.
- DE 811360 discloses an arrangement for automatically opening the protective flaps on the line coupling of an automatic vehicle hitch.
- the assembly consists of one on the front of the protective flap arranged elastic bracket with such a curved end face that when they touch the end face of the counter protective flap, opening of both protective flaps is brought about by pivoting about a rotation or pivot axis arranged transversely to the longitudinal axis of the vehicle coupling on the coupling housing of the line coupling.
- Such automatic protective flaps are provided with a rubber element, for example, on the face contacting the counter-coupling, which serves to increase the friction on contact with the face of the protective flap of a counter-electrical contact coupling or a to create a certain form fit.
- These rubber parts which are usually extruded profiles or mats, are attached to the protective flap by gluing or riveting.
- the disadvantage of such a solution is that, with a protective flap curved around several axes, such parts are difficult to attach, or special attachments are required for this purpose must manufacture molded parts, which is associated with additional tool costs.
- An embodiment of a protective flap is known from the subsequently published DE 10 2019 132 642 A1, which has an at least partially applied spray elastomer coating on the front side to provide a surface with increased static friction in order to be able to interact better with the protective flap of a counter-coupling .
- the invention is therefore based on the object of providing an improved electrical contact coupling for an automatic central buffer coupling of a rail vehicle, which is characterized by trouble-free release and re-covering of the interface unit.
- a trouble-free synchronous opening of the protective flaps of the electrical contact couplings to be connected to one another is to be made possible by eliminating the disadvantages of the prior art.
- safe opening can also be achieved with more complex surface geometries on the end faces and under extreme weather conditions.
- the object is achieved with an electrical contact coupling for an automatic telbuffer coupling with a rail vehicle with the features of patent claim 1 .
- the object is also achieved with a central buffer hitch for a rail vehicle with the features of patent claim 13 .
- the present invention creates an electrical contact coupling for an automatic central buffer coupling of a rail vehicle, with a housing in which an interface unit with a plurality of connection elements ments, a protective flap for covering access to the connection elements of the interface unit, and an actuating device connected to the protective flap for moving the protective flap between a first position, in which the protective flap covers the access, and a second position, in which the protective flap releases access, where at least one rolling zone for interaction with a rolling zone of a counter electrical contact coupling is arranged on the front surface of the protective flap and wherein the rolling zone has form-fitting elements for forming a form-fitting connection that acts in at least one direction of the travel path of the protective flap when interacting having form-fitting elements of a counter-electrocontact coupling designed complementarily to the form-fitting elements of the electrical contact coupling.
- Form-fitting elements designed to be complementary to one another are understood to mean two form-fitting elements of different types that are designed to be suitable for entering into a form-fitting action that is effective in at least one direction, preferably two or more directions, when interacting with one another.
- the form-fitting elements are formed by projections and indentations designed to match one another.
- the present invention also creates a central buffer coupling for a rail vehicle, with a mechanical contact coupling, in particular a Scharfenberg coupling, for mechanically coupling rail vehicles, and an electrical contact coupling according to the invention.
- One idea of the present invention is to use the positive-locking elements to provide a surface on the protective flap which advantageously allows synchronous, preferably automatic opening of the protective flaps flap of electric contact couplings free of additional measures on the protection, in particular additional elements that are difficult to apply safely and even under the most extreme weather conditions, such as snow and ice, he allows.
- the form-fitting elements enable a secure mechanical interaction of the protective flaps of the electrical contact couplings to be coupled with one another, regardless of the surface roughness of the end faces. Furthermore, a form fit can also be guaranteed in the event of wear.
- the individual form-fitting element is integrally formed on the protective flap, in particular formed in one piece with the latter by means of a finishing process or a subsequent shaping process.
- the formation of the form-fitting elements by means of moldings on the protective flap is particularly advantageous. From the formations require no additional material or application of material and at the same time form the inner and outer surface of the protective flap. This offers the advantage of producing the form-fitting elements in a simple manner in one or very few work steps.
- the form-fitting elements are captive to the protective flap due to the integral design and do not generate any additional weight.
- the form-fitting elements in the individual rolling zones are arranged and designed in such a way that they are suitable for the form-fitting action that acts in at least one direction of the travel path of the protective flap when interacting with form-fitting elements of a mating electrical contact coupling that are designed to be complementary to the form-fitting elements of the electrical contact coupling when moving in the direction of the mating - Train electrical contact coupling.
- complementary means, in particular, opposite to one another, complementing one another in such a way as to be suitable for forming a positive fit with one another.
- the protective flap is rotatably or pivotably mounted and the front surface of the protective flap, in particular the at least one rolling zone provided or formed on this, is at least partially curved around the rotary or pivot axis.
- the bearing is in particular arranged and designed in such a way that when force is introduced on the end face when two protective flaps of two electrical contact couplings to be coupled to one another meet, when the electrical contact coupling moves perpendicularly to the pivot axis, a moment is generated around this and the end faces brought into operative connection roll off one another .
- an automatically opening protective flap can be provided, which is automatically actuated when the carriages of a rail vehicle to be coupled together and thus also the electrical contact couplings of these move towards one another, without additional drive devices and specially designed actuating devices being required, which results in lower costs Electrical contact coupling never strikes.

- the positive-locking elements arranged on the mutually mirror-inverted arrangement regions are each designed as positive-locking elements designed to be complementary to one another. This allows electrical contact couplings of the same type, which are provided on the mutually facing end areas of carriages, in particular rail vehicles, to be coupled to one another in a simple manner, with the release of the interface unit automatically due to the form fit and a force component in the longitudinal direction of the electrical contact coupling on the mitei Nander spent in operative connection protective flaps is effected.
- the release takes place automatically when the electrical contact couplings of two rail vehicles to be coupled to each other move towards each other, in particular wagons, in that after engagement of the mutually complementary form-fitting elements of electrical contact coupling and mating electrical contact coupling as the two wagons to be coupled together continue to move towards each other, the resulting the force component acting in the longitudinal direction of the protective flap causes a moment which causes the protective flap and counter-protective flap to roll or roll off.
