Definitions
- the present invention relates generally to track-guided vehicles and in particular to rail vehicles.
- the invention relates to coupling arrangements for track-guided vehicles, in particular rail vehicles, which contain automatic central buffer couplings.
- an automatic center buffer coupling in particular for a freight wagon of a rail vehicle, wherein the automatic center buffer coupling has an electrical contact coupling.
- an electrical contact coupling for an automatic central buffer coupling in particular for a freight wagon of a rail vehicle.
- Electric central buffer couplings which enable the quick and easy coupling and uncoupling of wagons in a track-guided vehicle, are basically known from rail vehicle technology.
- the mechanical coupling heads of the automatic central buffer coupling are connected in a force-locking manner in order to be able to transfer traction and impact forces between the wagons mechanically coupled in this way.
- electrical cables In addition to the mechanical coupling of adjacent cars, electrical cables, such as power supply cables and/or data cables, are usually coupled simultaneously via several contact terminals arranged in an electrical contact carrier.
- Conventional electrical contact couplings for automatic center buffer couplings of a rail-guided vehicle are usually arranged adjacent to the mechanical coupling head of the center buffer coupling and usually have a coupling housing in which an interface unit with a plurality of connection elements (terminals) is arranged.
- the electrical contact coupling also generally has a protective flap (also referred to as "flap" for short herein) 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.
- the flaps In order to be pressed against each other, the flaps must have a certain contour relative to their axis of rotation and protrude forwards beyond the coupling plane. The flap that protrudes forwards when closed is then located above the housing of the electrical contact coupling when open.
- the flap of the electrical contact coupling When the housing of the electrical contact coupling is moved forwards towards the coupling plane, the flap of the electrical contact coupling is folded upwards by a control arm.
- the tension springs on the flap run over a dead center when the flap is opened, so that the tension springs keep the flap closed when closed and open when opened.
- the electrical contact coupling known from the publication DE 40 13 493 A1 requires a sensor system that detects the state of the mechanical coupling. In addition, compressed air is required to move the electrical contact coupling into the coupling plane, which supplies the movement cylinder of the electrical contact coupling drive.
- Another disadvantage of the electric contact coupling known from passenger transport is that it also requires a relatively large installation space. By providing the necessary sensors and control for the Pneumatic drive also increases the weight and complexity of the electrical contact coupling.
- the present invention is based on the object of providing an electrical contact coupling for an automatic central buffer coupling, which is characterized by a simple and robust design, whereby the coupling process of the electrical contact coupling should be purely mechanical and without its own pneumatic drive, without sensors and without control.
- the electrical contact coupling should have as low an overall height as possible, both in the closed and in the open state.
- the task is to specify an automatic central buffer coupling, in particular for a freight wagon of a rail-guided vehicle with a corresponding electrical contact coupling.
- the invention relates in particular to an electrical contact coupling which has a housing with at least one electrical contact carrier which has contact terminals for electrical connections.
- the housing of the electrical contact coupling according to the invention is longitudinally displaceable in the coupling direction relative to a coupling head of the central buffer coupling between a first position in which the electrical contact coupling is in its rest position ready for coupling and a second position in which the electrical contact coupling is in its coupled position.
- the solution according to the invention does not use a complex pneumatic feed for the longitudinal displacement of the housing of the electrical contact coupling. Rather, the solution according to the invention provides that the electrical contact coupling has a spring mechanism with which the housing is pre-tensioned and moved into the second position.
- the preload force of the spring mechanism can be used to longitudinally displace the housing in the coupling direction.
- a stop mechanism is further provided in this context, by means of which the movement sequence of the housing between the first and second position is controlled.
- the spring mechanism serves as preferably the only drive for moving the housing of the electrical contact coupling from the first position to the second position.
- the housing of the electrical contact coupling In the first position of the housing of the electrical contact coupling, the housing is tensioned towards the second position of the housing due to the spring mechanism.
- the housing of the electrical contact coupling is supported by the stop element on the control element. If the control element is not moved, the housing of the electrical contact coupling does not move either.
- the stop mechanism has a stop element connected to the housing of the electrical contact coupling, which, due to the preload force of the spring mechanism, strikes or pushes against a control element mounted so as to be rotatable about an axis running perpendicular to the coupling direction.
- the control element is designed in such a way that When the control element is rotated about the axis perpendicular to the coupling direction, the housing is displaced longitudinally relative to the coupling head of the central buffer coupling.

- control element is mounted so as to be rotatable relative to the electrical contact coupling and in particular relative to the housing of the electrical contact coupling about the axis running perpendicular to the coupling direction, wherein furthermore the housing of the electrical contact coupling is mounted so as to be longitudinally displaceable relative to the control element in the coupling direction.
- the control element is coupled or can be coupled and in particular operatively connected or operatively connected to a coupling lock designed as a rotary lock of the automatic central buffer coupling in such a way that a rotation of the coupling lock designed as a rotary lock about a main axis, namely between an uncoupled position and a coupled position of the coupling lock designed as a rotary lock, the control element is rotated in a preferably synchronous manner about the axis running perpendicular to the coupling direction.
- the control element is designed at least partially or in regions as a cam disk, wherein the stop element is pressed against an edge region of the control element designed at least partially or in regions as a cam disk due to the pre-tensioning force of the spring mechanism, wherein in a state in which the coupling lock of the automatic central buffer coupling designed as a rotary lock is in the uncoupled position, the stop element is pressed against a first edge region of the control element designed at least partially or in regions as a cam disk, and then, when the coupling lock of the automatic central buffer coupling designed as a rotary lock is transferred from the uncoupled position to the coupled position, the stop element is moved along a second edge region of the at least partially or partially designed as a cam disk control element, wherein the first edge region of the control element, at least partially or partially designed as a cam disk, is preferably partially complementary to a peripheral geometry of the stop element and in particular is trough-shaped.
- control element is designed as a cam disk at least partially or in regions, wherein the stop element is pressed against an edge region of the control element designed as a cam disk at least partially or in regions due to the prestressing force of the spring mechanism and thus the movement resulting from the rotation of the control element is tapped or can be tapped.
- the stop element is designed as a guide roller that is pressed against the edge area of the control element, which is designed as a cam disk at least partially or in part, due to the preload force of the spring mechanism.
- the stop element is designed as a guide roller that is pressed against the edge area of the control element, which is designed as a cam disk at least partially or in part, due to the preload force of the spring mechanism.
- control element is designed in such a way that when the control element is initially rotated about the axis running perpendicular to the coupling direction, the housing is initially moved, in particular in a pulse-like manner, relative to the control element and/or relative to the coupling head of the central buffer coupling, in particular in a direction, in particular longitudinal direction, opposite to the coupling direction, wherein subsequently and when the control element is rotated further about the axis running perpendicular to the coupling direction, the housing of the electrical contact coupling is displaced longitudinally in the coupling direction relative to the control element and/or relative to the coupling head of the central buffer coupling.

- the stop element is designed at least partially or in regions as a cam disk and the control element as a lever element, wherein the stop element designed at least partially or in regions as a cam disk is pressed against the control element designed as a lever element due to the prestressing force of the spring mechanism.
- control element designed as a lever element has a guide roller against which - at least temporarily when rotating the control element about the axis running perpendicular to the coupling direction - an edge region of the stop element designed at least partially or in regions as a cam disk is pressed due to the pretensioning force of the spring mechanism.

- the solution according to the invention is therefore particularly suitable for the control element to be rotated, for example, by a main bolt of the mechanical coupling that rotates during mechanical coupling.

- the electrical contact coupling according to the invention preferably has a locking device associated with the housing of the electrical contact coupling, with the aid of which the housing of the electrical contact coupling can be locked relative to the coupling head of the central buffer coupling if required.
- the locking device has a blocking element which can be introduced into a longitudinal displacement path of the carrier between the carrier and the second stop, in particular manually, if required, and in particular manually pivotable, which is designed to block a movement of the housing of the electrical contact coupling relative to the coupling head of the central buffer coupling in its state introduced into the longitudinal displacement path and preferably pivoted in.
- the stop element connected to the housing of the electrical contact coupling no longer strikes against the control element which is mounted so as to be rotatable about the axis running perpendicular to the coupling direction, when the coupling lock of the automatic central buffer coupling, which is designed as a rotary lock, is turned from its uncoupled position to the coupled position.

- the electrical contact coupling has a preferably detachably attachable cover for at least partially or regionally covering at least one upper side of the housing of the electrical contact coupling. This also provides further protection for the components of the electrical contact coupling.
- the cover is designed in particular in the form of a bent sheet, preferably with stiffened beads, and is designed to be placed from above on the housing of the electrical contact coupling.
- the cover is designed to rest on both sides at preferably exactly three points when placed on the housing of the electrical contact coupling.
- the invention further relates to an automatic central buffer coupling, in particular for a freight wagon of a track-guided vehicle according to the independent patent claim 38.
- the automatic central buffer coupling is in particular a Scharfenberg coupling. It has a coupling head for the mechanical and force-locked connection of a first wagon with an adjacent second wagon and an electrical contact coupling of the type according to the invention described above, arranged above the coupling head.
- the coupling head has a coupling head housing and a coupling closure, wherein the coupling closure is designed as a rotary closure with a coupling eyelet and a frog, wherein the frog is rotatable about a main axis between a coupled position and an uncoupled position, wherein the coupling eyelet is connected to the frog with a first end rotatable about a coupling eyelet axis and has a free end, and wherein the frog has a mouth which is arranged to receive a second end of a coupling eyelet of a compatible coupling head of a counter-coupling.
- the stop mechanism of the electrical contact coupling has a stop element connected to the housing of the electrical contact coupling, which, due to the preload force of the spring mechanism of the electrical contact coupling, strikes or pushes against a control element mounted so as to be rotatable about an axis running perpendicular to the coupling direction, wherein the control element is designed such that when the control element is rotated about the axis running perpendicular to the coupling direction, the housing of the electrical contact coupling is displaced longitudinally relative to the coupling head of the central buffer coupling.
- the axis running perpendicular to the coupling direction, about which the control element of the electrical contact coupling is rotatable relative to the housing of the electrical contact coupling coincides at least partially or in some areas with the main axis of the heart of the coupling head of the central buffer coupling, wherein when the heart is rotated about the main axis, the control element of the electrical contact coupling is preferably also rotated.
- the automatic central buffer coupling has in particular a coupling head with a coupling housing and a coupling element with locking mechanism.
- the coupling lock which serves as a coupling element, is designed in particular as a rotary lock with a coupling eye and a frog, whereby the frog can be rotated about a main axis between a coupled position and an uncoupled position.
- the coupling eye which also serves as a coupling element, is connected to the frog in particular with a first end or with a first end region so as to be rotatable about a coupling eye axis and has a second free end or a second free end region.
- the frog has a mouth for receiving a corresponding second end or a corresponding second end region of a coupling eye of a compatible coupling head of a counter-coupling.
- a spring accumulator can be assigned to the core.
- the core can be rotated against the force of the spring accumulator from the coupled position to the uncoupled position and by the force of the spring accumulator from the uncoupled position to the coupled position.
- the uncoupled position is also generally referred to as the ready-to-couple position, since in this position the center buffer couplings of the two wagons can be moved against each other and coupled.
- the dome lock or its core can also be turned into a position that is too tight compared to the dome-ready position, i.e. opened more than necessary. In this over-tightened position, the spring accumulator is maximally tensioned.
- this over-extended position is also a position ready for coupling or uncoupling. Furthermore, such a position ready for coupling or uncoupling is also referred to as a waiting position.
- the locking mechanism which holds the coupling lock in the appropriate position or releases it to change to another position by turning the frog, has, for example, a piston that can be moved against a spring force in the coupling direction of the central buffer coupling and a ratchet rod that can be moved transversely or diagonally to the coupling direction.
- the ratchet rod is, for example, connected to the frog in an articulated manner and is moved by the frog when it is turned from the coupled position to the uncoupled position.
- Position can be moved into a locking position in which the latch rod blocks rotation of the frog backwards, ie in the direction from the uncoupled position to the coupled position.
- the plunger in turn, can be movable between a first position and a second position. In the first position, in which the plunger is displaced against the spring force, the plunger blocks the latch rod in the locking position and in the second position, in which the plunger is displaced from the first position by the spring force, the plunger releases the latch rod from the locking position.
- the two coupling locks are loaded exclusively by tensile forces, which are evenly distributed between both coupling eyes within the parallelogram formed by the coupling eyes and the frog pieces.
- the profile generally comprises, as is also advantageous in the present invention, a cone and a funnel, which are enclosed by a wide, in particular flat, front surface.
- the profile can be formed by a separate front plate that is attached to the front of the coupling head housing.
- the profile can form sliding and centering surfaces with the cone or funnel and in particular determine the gripping area in terms of lateral, vertical and angular offset. When the coupling heads meet, they center themselves and slide into each other.
- a decoupling device turns both coupling locks, i.e. the two frogs, against the force of the spring accumulators until the coupling eyes slide out of the frogs' mouths.
- the rotating frogs should move the ratchet rods so far that when the vehicles or wagons are separated, the frogs are prevented from turning back from the over-drawn position beyond the coupling-ready position by moving the ratchet rods into their locking positions.
- Uncoupling devices are known in different designs.
- manually operated, mechanical uncoupling devices have levers, cables and/or chain hoists that act on different types of latches and, when operated, cancel the latch position.
- Automated uncoupling devices comprise, for example, a pneumatic cylinder or an electric motor as a drive, in particular a linear actuator, which uncouples the central buffer coupling.
- the coupling process takes place when an automatic central buffer coupling of a first wagon or wagon body collides with an automatic central buffer coupling of an adjacent, second wagon or wagon body at low speed.
- the coupling heads create a mechanical connection between the two wagons or wagon bodies.
- both automatic central buffer couplings involved in the coupling process must be in an open, ready-to-couple state.
- the stable states "coupled” and "open” there is another state for each automatic central buffer coupling, which is called the "buffer position". In this state, the wagons or wagon bodies can be pushed, with the pressure forces being transmitted via the automatic central buffer couplings, which in the classic screw coupling is done via the side buffers of the wagons or wagon bodies.
- the buffer position described is required, for example, for shunting operations on the hump and the so-called pushing and running off.
- the hump is an infrastructure facility for re-sorting train formations.
- the hump is divided into three basic areas, namely the entry group, the hump and the direction track.
- the electrical contact coupling is always in its first position (rest position) when the central buffer coupling is in the buffer position or in the uncoupled ("open") position.
- the at least one electrical contact carrier with the contact terminals is protected or covered accordingly by the (closed) flap or cover.

- FIG. 1 shows schematically and in a side view an exemplary embodiment of an automatic central buffer coupling 1 according to the present invention.
- the automatic central buffer coupling 1 is in particular an automatic central buffer coupling for the Freight wagon of a rail vehicle. In particular, this is an automatic Scharfenberg coupling.
- the automatic central buffer coupling 1 has a coupling head 2 for mechanically and force-lockingly connecting a first wagon (not shown) to an adjacent second wagon (also not shown).
- the coupling head 2 comprises a coupling head housing in which a coupling closure is accommodated.
- the coupling closure is preferably designed as a rotary closure with a coupling eyelet and a heart piece, wherein the heart piece is rotatable about a main axis between a coupled position and an uncoupled position.
- the coupling eyelet is connected to the heart piece with a first end, preferably rotatable about a coupling eyelet axis, and has a free end.
- the heart piece has a mouth which is arranged to receive a second end of a coupling eyelet of a compatible coupling head of a counter-coupling.
- the coupling head 2 of the automatic central buffer coupling 1 thus formed forms a rigid connection when coupled to a coupling head 2 of a counter coupling. This coupling therefore enables the coupling of electrical connections in particular. This is done via an electrical contact coupling 8 attached to the coupling head 2.
- the electrical contact coupling 8 is arranged and fastened above the coupling head 2 of the mechanical coupling in a detachable manner by means of screws.
- the coupling head housing has a profile on the front.
- the profile is formed by a cone 4 and a funnel 5.
- the cone 4 and the funnel 5 are enclosed by a wide, flat front surface.
- the front surface can be formed by a front plate 3 detachably connected to the coupling head housing or by a front plate 3 formed integrally with it.
- the exemplary embodiment of the central buffer coupling 1 according to the invention shown in the drawings has a gripper 6.
- An exemplary embodiment of an electrical contact coupling 8 is arranged above the coupling head 2 of the automatic central buffer coupling 1 and is connected to the coupling head housing of the coupling head 2 of the central buffer coupling 1 by means of a screw connection.
- the electrical contact coupling 8 is shown in a state in which it is advanced or coupled. In this state, a flap 23 of the electrical contact coupling 8 is pivoted upwards so that the front area of the electrical contact coupling 8 is exposed.
- the electrical contact coupling 8 has a housing 9 with at least one electrical contact carrier 10.
- the at least one electrical contact carrier 10 has contact terminals 11 in particular for electrical connections.
- the housing 9 of the electrical contact coupling 8 is longitudinally displaceable in the coupling direction relative to the coupling head 2 of the central buffer coupling 1 between a first position in which the electrical contact coupling 8 is in its rest position ready for coupling and a second position in which the electrical contact coupling 8 is in its coupled position.
- the guide system comprises two parallel and Guide rods 21 extending in the coupling direction, with which a movement of the housing 9 of the electrical contact coupling 8 is guided during longitudinal displacement of the housing 9 relative to the coupling head 2 of the central buffer coupling 1.
- the guide rods 21 of the guide system are designed in particular as spring guide rods.
- each guide rod 21 of the guide system is assigned a spring mechanism 13 with which the housing 9 is preloaded into the second position, i.e. into the position in which the electrical contact coupling 8 is in its ready-to-couple or coupled position.
- the guide system has a carrier 22 with which the guide rods 21 together with the housing 9 of the electrical contact coupling 8, which can be displaced relative to the guide rods 21, above the coupling head 2 of the central buffer coupling 1 can be connected to the coupling head 2 of the central buffer coupling 1, for example via a screw connection.
- the electrical contact coupling 8 further comprises a flap 23 which is designed to cover an end face of the housing 9 with the contact terminals 11 in the first position of the housing 9.
- a flap 23 which is designed to cover an end face of the housing 9 with the contact terminals 11 in the first position of the housing 9.
- the flap 23 of the electrical contact coupling 8 is further designed such that it automatically swings open when the housing 9 moves from the first position to the second position, thus exposing the front face of the housing 9 with the contact terminals 11.
- FIG. 8C shows the electrical contact coupling 8 in the second position of the housing 9.
- a closed cam mechanism 24 is used to automatically swing open the flap 23.
- a guide groove is formed in a side plate, into which a guide element, which is connected to the flap 23, engages.
- leg springs are used on both sides, which are located on the flap rotation axis and rest on the housing 9 of the electrical contact coupling 8 on the one hand and on the flap 23 on the other.
- leg springs always try to press the flap 23 in the closed position and thus support the closing when the housing 9 of the electrical contact coupling 8 moves back and in particular prevent rattling noises.
- the guide contour or guide groove is also designed in such a way that the flap 23 cannot be opened by hand when the electrical contact coupling 8 is retracted, but can only be pivoted upwards by approx. 1° before the bolt rests on the sheet metal. This prevents people from accidentally or unauthorizedly touching the contacts located under the flap 23.
- the housing 9 In the advanced, open state without counter-coupling, the housing 9 is pushed out approx. 3 mm beyond the coupling plane. If the electrical contact couplings of two arrangements to be coupled meet, they move backwards against their compression springs and are pressed against one another by them.
- FIG. 2 shows in particular that the electrical contact coupling 8 has centering members/centering elements 25 which align the electrical contact couplings 8 with one another. Due to the extremely flat flap 23 of the electrical contact coupling 8, the centering elements 25 cannot be arranged in an area covered by the flap 23. Therefore, in the solution according to the invention, the centering elements 25 are arranged laterally and below the flap 23.
- a stop mechanism is used in the electrical contact coupling 8 according to the invention.
- the stop mechanism has a stop element 12 connected to the housing 9 of the electrical contact coupling 8, which, due to the preload force of the spring mechanism 13 of the electrical contact coupling 8, strikes or pushes against a control element 14 mounted so as to be rotatable about an axis running perpendicular to the coupling direction.
- control element 14 is designed such that when the control element 14 is rotated about the axis running perpendicular to the coupling direction, the housing 9 is displaced longitudinally relative to the coupling head 2 of the central buffer coupling 1.
- control element 14 of the stop mechanism is designed at least partially or in regions as a cam disk 15, wherein the stop element 12 of the stop mechanism is pressed against an edge region of the control element 14 designed at least partially or in regions as a cam disk 15 due to the preload force of the spring mechanism 13 of the electrical contact coupling 8 and thus the movement resulting from the rotation of the control element 14 is tapped or can be tapped.
- the stop element 12 is designed as a guide roller 16 which, due to the prestressing force of the spring mechanism 13, is pressed against the edge region of the control element 14 which is designed at least partially or in regions as a cam disk 15.
- FIG. 6A, B An alternative design for the stop mechanism is shown in FIG. 6A, B.
- the stop element 12 is designed at least partially or in regions as a cam disk 15 and the control element 14 as a lever element 17, wherein the stop element 12 designed at least partially or in regions as a cam disk 15 is pressed against the control element 14 designed as a lever element 17 due to the prestressing force of the spring mechanism 13.
- control element 14 designed as a lever element 17 it is advisable for the control element 14 designed as a lever element 17 to have a guide roller 18 against which - at least temporarily when the control element 14 is rotated about the axis running perpendicular to the coupling direction - an edge region of the stop element 12 designed at least partially or in regions as a cam disk 15 is pressed due to the preload force of the spring mechanism 13.
- FIG. 7A B a further embodiment of the stop mechanism is shown.
- control element 14 is designed as a closed cam disk 15 with a guide groove 19 and the stop element 12 as an element (guide element 20), in particular a sliding block, which is at least partially or regionally received in the guide groove 19.

- the control element 14 is formed on an end region of an extension of the main bolt 7.
- the housing 9 of the electrical contact coupling 8 is not yet pushed forward when the automatic central buffer coupling 1 is ready for coupling. This longitudinal displacement in the coupling direction is prevented by the stop mechanism.
- a stop for example in the form of a roller, is provided on the underside of the housing 9 of the electrical contact coupling 8. (guide roller 16), while a cam disc 15 is attached to an extension of the main bolt 7 of the central buffer coupling 1.
- the cam disk 15 When ready for coupling, the cam disk 15 points to the rear so that the roller or the stop rests on the larger diameter of the cam disk 15.
- the spring mechanism 13 can therefore not move the housing 9 of the electrical contact coupling 8 forward in the coupling direction.
- the main bolt of the automatic central buffer coupling 1 rotates forwards with the cam disc 15, thus releasing the movement of the housing 9 of the electrical contact coupling 8 in the coupling direction.
- the spring mechanism 13 of the electrical contact coupling 8 pushes the housing 9 of the electrical contact coupling 8 forwards along the guide rods 21.
- the advance is geometrically limited by the shape of the cam disc 15.

- the locking mechanism 26.1 shown in FIG. 9 is designed as a locking pin. This is inserted through a hole in the carrier 22 and penetrates into an underlying hole in the housing 9 of the electrical contact coupling 8, so that the housing 9 of the electrical contact coupling 8 can no longer be moved forward.
- the locking device 26.1 it is not absolutely necessary for the locking device 26.1 to have a hole in the housing 9 of the electrical contact coupling 8 into which the locking pin is inserted. It could also be a simple contact surface which rests against the pin from behind and thus prevents the housing 9 of the central buffer coupling 1 from moving in the coupling direction.
- the provision of such a locking mechanism 26.1 has the advantage, particularly during maintenance work. The contacts/terminals of the electrical contact coupling 8 are thereby safely protected against access.
- the locking device 26.1 is used, for example, when coupling to couplings that are not electrically compatible.

- control element 14 designed as a cam disk 15 is designed such that when the control element 14 is initially rotated about the axis running perpendicular to the coupling direction, the housing 9 of the electrical contact coupling 8 is initially moved, in particular in a pulse-like manner, relative to the coupling head 2 of the central buffer coupling 1, in particular in a direction opposite to the coupling direction, wherein subsequently and upon further rotation of the control element 14 or the cam disk 15 about the axis running perpendicular to the coupling direction, the housing 9 of the electrical contact coupling 8 is displaced longitudinally relative to the coupling head 2 of the central buffer coupling 1 in the coupling direction.
