Description

Coupler arrangement structure

The invention relates generally to a coupler arrangement, in particular a hybrid coupler arrangement or a transition coupler arrangement, for a track-guided vehicle, in particular a rail vehicle, having at least one first coupler device with a coupler head of an automatic coupler, which is guided into or out of a coupler plane as required.

Coupler arrangements for the optional use of different coupler devices for coupling with corresponding mating couplers are generally known from the rail vehicle technology and are used for connecting rail vehicles which are equipped with different coupler systems (for example on draw hooks)

-a coupler). In this case, the intermediate coupling is generally placed manually, for example, on a hook of a screw coupling, while the coupling process with the central buffer coupling can be carried out automatically.

Conventional coupling arrangements for hybrid coupling between an automatic coupler and, for example, a screw-connection coupler generally have a coupler carrier which is designed at least in some regions as a housing and in which a coupling lock can be accommodated in order to mechanically connect the transition coupler to a coupling lock provided in the coupler head of the automatic central buffer coupler. In the coupled state, the end face of the transition coupler then bears against the end face of the coupler head of the automatic central buffer coupler. On the end opposite the end face of the transition coupler, a coupler clip can be provided as an interface structure of the hook module, which can be accommodated, for example, in a hook of a screw connection coupler and thus can ensure the mechanical connection of the transition coupler. In this embodiment, the coupler clip of the transition coupler is placed on the pull hook of the screw connection coupler to be fitted. For this purpose, the transition coupling is provided with brackets of the same type which are arranged parallel at a distance from one another on both sides of its rear end and which are connected to one another at their free ends by means of pins. The pin retains the coupler clip of the transition coupler in the mouth of the draw hook. On both sides of the conventional transition coupling, an angle lifter is arranged, which comprises a first and a second control rod. The control levers on both sides of the transition coupling are connected to one another and to one another by a common axis, wherein the axis serves as an abutment surface on the end face of the draw hook, so that the center position of the transition coupling can be adjusted. By providing the angle bars, a high degree of centering can be achieved in the transition couplers known from the prior art. However, manual handling and in particular manual insertion of the transition coupling into the interface between the couplings to be fitted, for example a draw hook of a screw-on coupling, becomes more difficult, since it is not possible for the operator to support the weight of the transition coupling on the one hand and to place the device for high centering on the draw hook in a correct manner on the other hand.

Another coupling arrangement which can be used in particular as a shunting coupling for rail-guided vehicles is known, for example, from EP2529994 A1. The coupler is characterized in that it can be connected to different couplers, so that different shunting tasks can be performed by the same coupler arrangement without changing it and with reduced commissioning time. In particular, both standard gauge railway couplers and subway couplers can be coupled with the coupler arrangement without manual intervention by an operator for this purpose. For this purpose, the coupler arrangement known from EP2529994A1 has a coupler head changer for automatically changing coupler heads of different structural forms and/or different types into the vertical coupler plane defined by the coupler arrangement. The coupler head changer is correspondingly suspended on the draw hook of the screw coupling by means of a relatively complex device. Although this embodiment allows for the automatic exchange of coupler heads of different structural forms and/or different types into the coupler plane defined by the coupler arrangement. This embodiment is disadvantageous if a screw connection coupling can be coupled. For this purpose, it is necessary to remove the coupler head changer from the draw hook, which in turn requires a considerable amount of adjustment time.

Other systems are characterized in that at least two coupler devices of different design are provided, which can be pivoted into the coupling plane as required.

In detail, EP 080759A1 discloses a coupling arrangement with a tie rod and a draw hook fixed thereon and at least two different coupling devices which are pivotably supported on the tie rod about a horizontal axis, and with an operating device for pivoting the individual coupling devices into a coupling plane. The actuating device comprises a drive rod, which acts with one of its ends in an articulated manner on the coupling device or on a connecting part associated therewith. The other end is guided in a slotted hole of a support for a lifting cylinder, which is guided on a tension rod, wherein the lifting cylinder has a piston rod acting on the end of the drive rod. Locking means for the drive rod are also provided. By means of the coupler arrangement disclosed in EP 080759A1, a draw hook or one of the two coupler devices can alternatively be used. In the desired use of the retractor, both coupling devices are pivoted upwards, the respective upper coupling device being locked in its position, while the other coupling device is lowered by means of the lifting cylinder and the retractor is released. If the lower coupler device is to be used, it is pivoted into the coupler plane by means of the lifting cylinder. This is similarly done when the upper coupler device is desirably used. The operating device is arranged below the tie rod and the arrangement is relatively complex in design.

A coupler arrangement of the type according to the invention is known from EP3590784 A1. It comprises a tie rod having a first end region for connection to the car and a second end region opposite the first end region. In the region of the second end of the pull rod, a hinge device is provided, by means of which the coupling head of the automatic coupling and the pull ring are pivotably supported about a horizontal hinge axis. The coupling head of the automatic coupling is connected in a rotationally fixed manner to the articulation device. An operating device is provided for pivoting the coupler head of the automatic coupler into or out of the horizontal coupler plane as desired. It comprises a drive which contains a cable winch which is supported on a frame fixed to the car and by means of which the deflection can be effected. The disadvantage of this design is primarily the arrangement of the operating device, which depends on the installation and the application in the vehicle.

The object of the present invention is therefore to provide a coupler arrangement which is connected on the one hand to different automatic coupler devices, in particular standard-gauge railway or subway couplers or similar central buffer couplers, and on the other hand to different types and types of coupler devices, for example screw-connection couplers, in order to minimize the commissioning time, so that different commissioning tasks can be carried out without the transition coupler and in particular the hook module of the transition coupler having to be removed from the hook of the screw-connection coupler and without the high centering which has been carried out in the past.

This object is achieved according to the invention by a coupler arrangement according to claim 1. Advantageous embodiments are described in the dependent claims.

The coupling arrangement according to the invention for a rail-guided vehicle, in particular a rail vehicle, comprises

A pull rod having a first end region for connection to a vehicle and a second end region opposite the first end region, the coupler device comprising a hinge device arranged in the second end region of the pull rod, by means of which at least one first coupler device is pivotably supported about a horizontal hinge axis, wherein the first coupler device has a coupler head of an automatic coupler, which is connected in a transmission-proof manner to the hinge device,

an operating device for pivoting the coupler head of the automatic coupler into or out of the horizontal coupler plane as required;

characterized in that the operating device is fixed on the tie rod and comprises at least one drive which acts on the articulation means eccentrically with respect to the horizontal articulation axis and is designed to pivot the coupler head of the automatic coupler into or out of the horizontal coupler plane as required.

The solution according to the invention provides the advantage of a coupler arrangement which is suitable for adapting to different coupler systems by pivoting at least a first coupler means out of a coupler plane, while at the same time providing the necessary space for introducing and arranging a second coupler means in a very compact structural manner in the coupler plane, which is different from the first coupler means. By arranging the operating device on the tie rod, the coupling arrangement can be used in different connection environments, in particular in a car embodiment, without vehicle-side modifications of the operating device. The coupling arrangement can be provided as a preassembled constructional unit, comprising the operating means for connecting the different coupling systems, and can be constructed and designed very compactly.

The term "transmission-proof" (mitnahmefest) or "torsion-proof" is understood to mean, in particular, a connection between two components which, when one of the components is moved, enables the other component to be forced together in the same manner. The term "non-driven" can be realized here by a direct fixed connection between two components or indirectly by means of intermediate components.

In detail, embodiments according to the invention allow the automatic coupler to be pivoted out of the coupler plane into a plane at an angle thereto and back to the coupler plane as required in order to hold the automatic coupler in the coupler arrangement.

The coupler arrangement preferably comprises at least one further second coupler means, which is designed differently from the first coupler means. The second coupler arrangement differs from the first coupler arrangement in the coupler type or dimensioning. The second coupling means are preferably articulated at an angle to the first coupling means, as viewed in the circumferential direction about the articulation axis, on the articulation means arranged in the region of the second end of the tension rod or are pivotably supported on the articulation means about a horizontal articulation axis. By providing further second coupler means in the coupler arrangement, it is available at any time and can be brought into a corresponding position in the coupler plane or a position outside the coupler plane by means of the operating device. The costly manual commissioning can be dispensed with.

In this connection, it is particularly suitable for the articulation means of the pull rod to have a first articulation arm which is pivotable about a horizontal axis and on which the first coupling means is preferably detachably and/or replaceably fastened or fastenable. For this purpose, according to one embodiment of the tie rod according to the invention, the first hinge arm has an interface region, by means of which the coupling head of the automatic coupling is replaceably fastened to the first hinge arm.

In this connection, it is conceivable, for example, for the interface region to have at least one housing arrangement. The interface region serves essentially to detachably mechanically connect the first hinge arm of the tie rod to a support structure of the coupler head, in particular of the coupler head of the automatic coupler.

In particular, in this way, a modular or modular construction of the coupler arrangement is achieved, which is composed essentially of the tie rod and the coupler head designed separately therefrom. Since the first articulated arm of the tie rod can be connected to different coupler heads via the interface region, the coupler arrangement according to the invention is suitable in this case for coupling to vehicles having couplers of different types or of different types, wherein in particular the coupler arrangement of the draw hooks of the shunting vehicle does not need to be modified or replaced. In particular, different shunting tasks can be carried out with the solution according to the invention, so that it is an extremely flexible system as a whole.

In order to simplify the replacement of the coupling head, it is provided according to an embodiment of the solution according to the invention that the tie rod has an interface region, by means of which the first hinge arm of the tie rod is mechanically or detachably connected to the support structure of the coupling head.

Different embodiments are conceivable for the interface region. In particular, it is suitable here for the interface region to have at least one housing arrangement. In addition or as an alternative thereto, the interface region can also have at least one latching means with at least one pull pin (german: abseckbolzen).

In an embodiment of the tie rod according to the invention, the joint device of the tie rod has a second joint arm which is pivotable about a horizontal axis and to which a coupling device, in particular a pull ring and in particular a pull ring compatible with a screw coupling of a shunting vehicle, is or can be fixed. In this case, it is preferred that the second hinge arm is connected to the first hinge arm of the tension rod in such a way that both hinge arms pivot jointly, in particular exclusively jointly, about a horizontal axis.

The second hinge arm is preferably connected to the first hinge arm in such a way that the two hinge arms pivot jointly, in particular exclusively jointly, about a horizontal axis, wherein an angle of 80 ° to 100 °, preferably an angle of approximately 90 °, opens between the first hinge arm and the second hinge arm.

In an advantageous embodiment, the actuating device is fastened to the tie rod above the horizontal coupler plane. Depending on the position of the automatic coupler, its position in the coupler plane, the design of the locking and operating device, it is thus not subject to the gravitational loading of the individual coupler devices.

In an embodiment, the at least one drive acts at least indirectly on a rocker which is connected in a rotationally fixed manner to the horizontal joint axis to form a drive/rocker unit. In a particularly advantageous embodiment, the drive acts directly on the rocker. In this case, the transmission of the required torque can be achieved directly without additional conversion. The operating device is characterized by a minimum of components required.

In order to ensure a uniform load distribution and to keep the operating device small and compact in design during pivoting out and pivoting in, it comprises drive means/rocker units arranged on both sides of the tie rod with reference to the tie rod. The latter can thus be constructed considerably smaller and the installation space freed for this purpose can be used for other purposes.

In a particularly advantageous embodiment, the individual drive is designed as a hydraulic or pneumatic linear motor which is attached to a support device arranged on the tie rod. The use of preferably pneumatic linear motors provides the advantage that no additional energy sources have to be provided for these drives, but rather they can be integrated into the already existing compressed air system of the rail vehicle or can be connected thereto.

In an advantageous manner, the single hydraulic or pneumatic linear motor is designed either as a double-acting lifting piston/cylinder unit or as a single-acting lifting piston/cylinder unit with a return device, in particular a return spring. In the first case, the different functional positions can be achieved by charging and discharging the individual pressure chambers, and in the second case, the restoring force is predetermined.

It is preferably provided structurally that the support is formed by a sheet metal shaped part, in particular a profile part, which is fastened to the tie rod, wherein the fastening can be effected by a force-fitting connection, a form-fitting connection or preferably by a material-bonded connection. The support provides a receptacle for the drive device, which is preferably designed as a lifting piston/cylinder unit with a connection for connection to a compressed air supply system. Preferably, means for controlling the loading of the individual connections are provided on the lifting piston/cylinder unit, which in the simplest case is designed in the form of a valve arrangement.

There are a number of possible solutions for the design of the single connection against transmission between the articulation and the coupler head and/or between the articulation and the rocker. In an advantageous manner, a form-fitting connection is used. They can be designed in particular as a key/groove connection or as an oil pressure connection.

In a further embodiment, the transmission-proof connection between the articulation and the coupling head and/or the transmission-proof connection between the articulation and the rocker can be designed as a force-fitting connection.

In a particularly advantageous manner, the drive device/rocker unit is arranged and designed in such a way that the piston of the lifting piston/cylinder unit is relieved in the position of the pivoting of the automatic coupling device into the coupling plane.

In an advantageous embodiment, at least one locking device is also provided, which in the pivoted position of the first coupling device enables the unloading of the drive device.

Furthermore, advantageously, there is also a possibility of locking in the pivoted-out position.

In terms of crash safety, it is basically advantageous to integrate energy dissipation and/or damping elements in the tie rods of the transition couplings in order to damp the tensile and/or compressive forces transmitted by the tie rods during driving. The energy-consuming and/or damping element is preferably regenerative, for example in the form of a spring device or a spring pack. Of course, it is also conceivable to use destructively designed consumable elements or a combination of destructive and regenerative components.

Fig. 1 shows a highly simplified schematic representation of the basic structure of a coupler arrangement 100 according to the invention in the form of a transition coupler or hybrid coupler. It comprises a drawbar 1 and at least one first coupling device 20 in the form of an automatic coupling 21 which is pivotably supported on the drawbar 1 about a horizontal geometric axis a. Furthermore, a second coupler device 30 is provided.

The tie rod 1 has a first end region 2 on the cabin side, by means of which first end region 2 the tie rod 1 is preferably detachably connected to a cabin, in particular a cabin of a freight or shunting vehicle or to its chassis. Furthermore, the tie rod 1 has a second end region 3 opposite the first end region 2. On this second end region 3, a hinge device 4 is provided in order to pivot the coupler head 22 of the first coupler device 20, in particular the automatic coupler 21, into the horizontal coupler plane KE as required. The hinge arrangement 4 comprises at least one pin 5 of the coupler arrangement viewed horizontally in a mounting bearing on the vehicle. It is rotatably mounted in a through-opening in the forked end region 3 of the tie rod 1. This pivoting takes place about a horizontal axis a which corresponds to the geometric and in this position horizontal axis of the pin 5 and thus to the hinge axis GA of the hinge device 4.

The horizontal coupler plane KE can then be described by the longitudinal axis of the tie rod 1 and the vertical line perpendicular thereto, in particular the horizontal axis of the pin 5 or the hinge axis GA of the hinge device, viewed in the horizontal direction in the installed position on the rail vehicle.

The first coupling device 20, in particular the coupling head 22 of an automatic coupling 21, which is not shown in detail here, is connected in a rotationally fixed manner to the joint 4. This can be achieved by the integral design of the coupler head 22 with the hinge device 4, in particular the pin 5, or preferably by a detachable connection thereto.

Fig. 1 shows a first coupler arrangement 20 in a horizontal coupler plane KE. In order to be able to pivot the first coupler arrangement 20 out of or into the horizontal coupler plane KE, an operating device 6 is provided. The actuating device 6 is directly fixed on the tie rod 1 and comprises at least one drive 12 acting eccentrically with respect to the horizontal joint axis GA or designed on the joint 4, pivoting the coupling head 22 of the automatic coupling into or out of the horizontal coupling plane KE as required.

The actuating device 6, in particular the separate drive 12, is fastened to the tie rod 1 above the horizontal coupler plane KE. The fixing takes place for example on a bracket 17 connected to the tie rod 1. The holder can be connected to the tie rod in a detachable or non-detachable manner. The drive 12 acts at least indirectly on a rocker 13 connected in a rotationally fixed manner to the horizontal joint axis GA, in order to form a drive/rocker unit 14. In the case shown, the output 16 of the drive 12 is coupled to the rocker 13 via a hinged connection 15. Depending on the design of the rocker 13, the coupling of the drive means 12 takes place above or below the hinge axis GA in the position in which the first coupler means 20 is pivoted into the coupler plane KE.

Viewed in the longitudinal direction of the tie rod 1, the position of the joint axis GA and the connection or fastening of the drive 12 to the tie rod 1 are spaced apart from one another. The articulation on the pivot lever 13 is preferably carried out in the circumferential direction of the articulation axis GA in such a way that the force direction of the drive for introducing a moment on the pivot lever 13 coincides with the pivoting direction.

The drive 12 is preferably designed as a pneumatic linear motor. Fig. 1 shows an example of a pneumatic linear motor design in the form of a two-sided lifting piston/cylinder unit 18. It has at least two connections 19.1, 19.2, which are coupled to different pressure chambers in the cylinder in order to load different piston surfaces. The pressure chamber can be coupled to a pressure medium supply 25, which can be formed by the pressure medium system of the rail vehicle. In order to control the pressure medium supply of the lifting piston/cylinder unit 18, means for controlling the pressure medium supply are provided in the connection between the connections 19.1, 19.2 on the cylinder and the pressure medium supply system, which means are designed in the simplest case in the form of a valve arrangement.

The second coupler arrangement 30 may be designed in various ways. It is preferably formed by a pull ring 10 which can interact with a pull hook not shown here.

The second coupler means 30 pivots into the coupler plane at or after the first coupler means 20 pivots out of the coupler plane. For this purpose, the second coupling device 30 is preferably likewise mounted pivotably about a hinge axis GA. The support is preferably carried out directly on the joint 4 and in such a way that the two

coupling devices

20 and 30 are arranged at a predefined angle, preferably approximately 90 °, to one another and their pivoting is always positively coupled.

The position shown in fig. 1 of the first coupler device 20 corresponds here to a position I pivoted into the horizontal coupler plane KE. The direction of movement of the piston about the hinge axis GA and the drive means 12 is shown by means of an arrow.

Fig. 2 illustrates an advantageous design of the coupling arrangement 100 according to fig. 1 in the pivoted-out position II of the coupling device 20, in particular of the coupling head 22 of the automatic coupling 21. To illustrate the operating device more clearly, fig. 3b shows this position without the coupler head 22, while fig. 3a shows the pivoted position I without the coupler head 22. Like elements are given like reference numerals.

The hinge device 4 has a first hinge arm 7 which is pivotable about a horizontal axis, in particular a hinge axis GA, and on which a coupling head 22 of an automatic coupling 21 is detachably and/or replaceably fastened or fixable. The coupler head 22 is detachably connected to the hinge 4 via the interface region 9. In the case shown, this is achieved by means of an outer jacket connection.

An advantageous embodiment of the coupling arrangement 100 according to the invention provides that the coupling lock associated with the coupling head 22 is designed to be compatible in particular with the coupling head, in the manner of a funnel/cone structure, for example 10, 35, 330, 430, 55 or 140. However, other coupler head types or coupler head structure types are also conceivable, for example a coupler head of the wedge lock type, a coupler head of the BSI type or a coupler head of the GF type.

In the case of the tie rod 1 shown in fig. 2, it is furthermore provided that the joint 4 also has a second joint arm 8 which is pivotable about a horizontal axis, on which second joint arm 8 a second coupling device 30, in particular a pull ring 10, such as a pull ring 10 compatible with a screw coupling, is fastened or can be fastened, in order to be able to be coupled to the coupling arrangement 100, as well as to a screw coupling.

In this case, it is provided that the second joint arm 8 is connected to the first joint arm 7 of the joint 4 in such a way that the two

joint arms

7,8 pivot only jointly about the horizontal joint axis GA.

Between the first hinge arm 7 and the second hinge arm 8, an angle of 80 ° to 100 °, an angle of approximately 90 °, i.e. the two

coupling devices

20, 30 are positively coupled to one another with regard to a pivoting movement.

The two articulated

arms

7,8 are pivotably supported by a horizontally extending bolt 5, which bolt 5 is an integral part of the articulation 4 and defines a pivot axis GA of the articulation 4. In a figurative sense, the horizontally extending bolt 5 has the same function as a pull pin of a screw connection coupling.

In order to pivot the coupling head 22 of the automatic coupling 21, the actuating device 6 has, for pivoting into and out of the horizontal coupling plane KE as required, drive/rocker units 14 which are arranged on both sides of the tie rod 1, respectively, and which are fastened to the support 17 in a serial arrangement on the tie rod 1.

For the sake of clarity, fig. 3a and 3b show an embodiment of the coupler head 22 without the automatic coupler 21 in two functional positions of the coupler arrangement 100 according to fig. 2, namely a position pivoted into the coupler plane KE (fig. 3 a) and a position pivoted out of the coupler plane KE (fig. 3 b). Only the interface region 9, through which the coupling head 22 of the automatic coupling can be fastened to the first hinge arm 7 in an exchangeable manner, is visible on the first hinge arm 7. The interface region 9 has preferably at least one housing means.

The hinge device 4 comprises a horizontally extending pin 5, which defines a pivot axis for the first hinge arm 7 and a pull ring 10 compatible with the pull hook of the screw coupling, wherein the horizontally extending pin 5 is in particular designed as a pull pin of the screw coupling. The pin 5 is either designed in one piece with the

individual hinge arms

7,8 or is connected in a transmission-proof manner to the

individual hinge arms

7, 8. The anti-drive connection can be designed differently. Both force-fitting and form-fitting connections are conceivable.

The individual rockers 13 of the drive device/rocker unit 14 are connected in a rotationally fixed manner to the pin 5, in particular to the end regions thereof. The connection can be realized in a force-fitting manner or in a form-fitting manner.

In the illustrated case, the pin 5 is rotatably mounted in a through-opening in the fork-shaped end region 3 of the tension rod 1, to which the rocker 13 is fastened in each case in the end region of the pin 5 projecting out of the through-opening.

The single drive 12 is designed to raise and lower the piston/cylinder unit 18 and takes over the function of a pneumatic linear motor. The individual cylinders are for this purpose fixed to the support 17. The piston is preferably connected in an articulated manner to a rocker 13. The connection means are indicated with 15 and are realized eccentrically with respect to the hinge axis GA. Upon extension or retraction, the piston generates a torque about the hinge axis GA.

The fastening of the individual drives 12 to the support 17 is preferably carried out directly. In the simplest case, the support 17 is formed by a T-plate, on which a receptacle or a receiving device for a cylinder is provided. The bracket 17 and the receiving means may be formed by separate parts or in an alternative embodiment they may also be integrally formed in one part, for example in a plate part.

In the position I shown in fig. 3a, the piston of the lifting piston/cylinder unit 18 is retracted and locked in this functional position. For this purpose, a locking device 23 is provided, which secures the first coupling device in a position in the coupling plane KE opposite the end region 3 of the tension rod 1.

In the position II shown in fig. 3b, the first coupler means 20 is pivoted out of the coupler plane KE and the second coupler means 30 is pivoted into the coupler plane KE. In this position, the drive 12, in particular the piston of the lifting piston/cylinder unit 18, is extended.

Fig. 1 to 3b show an advantageous design of the coupling arrangement 100, in which the coupling head 22 of the automatic coupling 21 is pivoted out upward and the piston of the lifting piston/cylinder unit is in the retracted state in the pivoted-in position I. For this purpose, the drive means 12 are hinged on the rocker 13 below the hinge axis GA.

The pneumatic lifting piston/cylinder unit 18 is designed according to the embodiment according to fig. 5a as a lifting piston/cylinder unit 18 acting on both sides or according to fig. 5b as a lifting piston/cylinder unit 18 acting on one side. In the simplest case, the cylinder according to fig. 5a has two pressure chambers which can be supplied with pressure medium or can be discharged via corresponding connections 19.1 and 19.2.

According to fig. 5b, only one of the pressure chambers is charged and the return is effected by the spring force.

Fig. 4 illustrates the anti-transmission connection means 26 between the pin 5 and thus the hinge means 4 and the first coupler means 20. The connecting device is designed in the illustrated case as a form-fitting design and as a key/groove connection.
