Description

Technical Field

[0001] The present invention generally relates to a coupler arrangement structure for track-guided vehicles, particularly rail vehicles, especially a hybrid coupler arrangement structure or a transitional coupler arrangement structure, having at least one first coupler device with a coupler head having an automatic coupler, which is introduced or led out of the coupler plane as needed. Background Technology

[0002] Coupler arrangements for selectively utilizing different coupler devices for coupling with corresponding mating couplers are generally known from rail vehicle technology and are used to connect rail vehicles equipped with different coupler systems (e.g., on hooks). - Coupler). Here, the placement of the transition coupler, such as on the hook of the threaded connection coupler, is generally done manually, while the coupling process with the central buffer coupler can be carried out automatically.

[0003] Conventional coupler arrangements for mixed coupling between automatic couplers and, for example, threaded couplers typically have a coupler support designed as a housing, at least partially. This support can accommodate a coupling lock to mechanically connect the transition coupler to the coupling lock located in the coupler head of the automatic central buffer coupler. In the coupled state, the end face of the transition coupler rests against the end face of the coupler head of the automatic central buffer coupler. At the end opposite the end face of the transition coupler, a coupler clamp can be configured as an interface structure for a hook module, which can be accommodated, for example, in the hook of the threaded coupler, thus ensuring the mechanical connection of the transition coupler. In this embodiment, the coupler clamp of the transition coupler is placed on the hook of the threaded coupler to be adapted. For this purpose, the transition coupler has supports of the same type arranged parallel to each other on both sides of its rear end, interconnected at their free ends by pins. The pins hold the coupler clamp of the transition coupler in the opening of the hook. An angle lifter, comprising first and second control levers, is arranged on both sides of the conventional transition coupler. The control rods on both sides of the transition coupler are interconnected and vertically connected via a common axis, where the axis serves as a contact surface on the end face of the hook, thereby allowing adjustment of the transition coupler's center position. High centering can be achieved in transition couplers known in the prior art by using angle rods. However, manual operation, especially the manual insertion of the transition coupler into the interface between the coupler to be adapted, such as the hook of a threaded coupler, becomes more difficult because it is impossible for the operator to simultaneously support the weight of the transition coupler while correctly mounting the device used for high centering on the hook.

[0004] For example, another coupler arrangement structure is known from EP2529994A1, particularly suitable for use as a shunting coupler for track-guided vehicles. Its characteristic is that it can be connected to different couplers, allowing different shunting tasks to be performed using the same coupler arrangement structure without replacement and with reduced commissioning time. In particular, both standard gauge railway couplers and metro couplers can be coupled to this coupler arrangement without manual operator intervention. For this purpose, the coupler arrangement structure known from EP2529994A1 includes 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 structure. This coupler head changer is correspondingly suspended on a hook of the threaded coupler by a relatively complex device. While this embodiment allows for the automatic changing of coupler heads of different structural forms and / or different types into the coupler plane defined by the coupler arrangement structure, this implementation is disadvantageous if it can be coupled to a threaded coupler. Therefore, it is necessary to remove the coupler head changer from the pull hook, which requires a considerable amount of debugging time.

[0005] Other systems are characterized by providing at least two coupler devices with different structural configurations, which can be pivoted into the coupling plane as needed.

[0006] In detail, EP 080759A1 discloses a coupler arrangement having a pull rod and a hook fixed thereon, and at least two different coupler devices pivotally supported on the pull rod about a horizontal axis. The coupler arrangement also includes an operating device for pivoting individual coupler devices into the coupler plane. This operating device includes a drive rod, one end of which acts hingedly on a coupler device or a connector component associated with it. The corresponding other end is guided in an elongated hole in a bracket for a lifting cylinder guided on the pull rod, wherein the lifting cylinder has a piston rod that applies action to the end of the drive rod. A locking device for the drive rod is also provided. The coupler arrangement disclosed in EP 080759A1 allows for the selective use of either the hook or one of the two coupler devices. When the hook is desired to be used, both coupler devices pivot upwards, wherein the corresponding upper coupler device is locked in its position, while the other coupler device is lowered by means of the lifting cylinder and the hook is released. If the lower coupler device is to be used, it is pivoted into the coupler plane using a lifting cylinder. This is done similarly when the upper coupler device is desired. The operating equipment is located below the pull rod, and this arrangement is relatively complex.

[0007] A coupler arrangement of the type of the present invention is known from EP3590784A1. It includes a tie rod having a first end region for connection to a vehicle body and a second end region opposite the first end region. A hinge device is provided in the second end region of the tie rod, through which the coupler head and pull ring of an automatic coupler are pivotally supported about a horizontal hinge axis. The coupler head of the automatic coupler is connected to the hinge device in a non-transverse manner. An operating device is provided for pivoting the coupler head of the automatic coupler into or out of the horizontal coupler plane as needed. It includes an actuator containing a cable winch supported on a frame fixed to the vehicle body and through which deflection can be achieved. The main disadvantage of this design is the arrangement of the operating device, which depends on the installation and application on the vehicle. Summary of the Invention

[0008] Therefore, the technical problem to be solved by the present invention is to provide a coupler arrangement structure that, on the one hand, connects to different automatic coupler devices, especially standard gauge railway or subway couplers or similar central buffer couplers, and on the other hand, connects to different kinds and types of coupler devices, such as threaded coupling couplers, so as to minimize commissioning time and thus complete different shunting tasks without having to remove the transition coupler and the hook module of the transition coupler from the hook of the threaded coupling coupler and eliminating the need for the original height centering.

[0009] The technical problem is solved according to the present invention by a coupler arrangement structure for a track-guided vehicle.

[0010] The coupler arrangement structure for track-guided vehicles, particularly rail vehicles, according to the present invention includes...

[0011] A tie rod has a first end region for connection to a vehicle and a second end region opposite the first end region. The coupler device includes a hinge device disposed in the second end region of the tie rod, by which at least one first coupler device is pivotally supported about a horizontal hinge axis. The first coupler device has a coupler head of an automatic coupler that is anti-transmissionically connected to the hinge device.

[0012] Operating device for pivoting the coupler head of an automatic coupler into or out of the horizontal coupler plane as needed;

[0013] The operating device is fixed to the pull rod and includes at least one drive mechanism that acts eccentrically on the hinge mechanism relative to the horizontal hinge axis and is designed to pivot the coupler head of the automatic coupler into or out of the horizontal coupler plane as needed.

[0014] The solution according to the present invention provides advantages for the coupler arrangement structure. By pivoting at least a first coupler device out of the coupler plane, the coupler arrangement structure is suitable for adapting to different coupler systems, while providing the necessary space to introduce and arrange a second coupler device with a different structure than the first coupler device in the coupler plane in a very compact manner. By arranging the operating equipment on the tie rod, the coupler arrangement structure can be used in different connection environments, especially in carriage implementations, without requiring vehicle-side modifications to the operating equipment. The coupler arrangement structure can be provided as a pre-assembled structural unit, including operating devices for connecting different coupler systems, and can be constructed and designed very compactly.

[0015] The term "mitnahmefest" or "torsional ground" is specifically understood as a connection between two components that, when one component moves, forces the other component to move in the same manner. "Mitnahmefest" can be achieved either through a direct, fixed connection between the two components or indirectly through an intermediate component.

[0016] In detail, according to embodiments of the invention, the automatic coupler is allowed to pivot out of the coupler plane into a plane at an angle thereto as needed and pivot back to the coupler plane in order to hold the automatic coupler in the coupler arrangement structure.

[0017] The coupler arrangement preferably includes at least one additional second coupler device, which is designed differently from the first coupler device. The second coupler device differs from the first coupler device in its coupler type or size design. The second coupler device is preferably hinged circumferentially about a hinge axis in a hinge device located in the second end region of the tie rod, at an angle to the first coupler device, or pivotally supported about a horizontal hinge axis on the hinge device. By including the additional second coupler device in the coupler arrangement, it is always available and can be positioned in a corresponding position within or outside the coupler plane by an operating device. Costly manual adjustments can be eliminated.

[0018] In this regard, it is particularly suitable that the hinge mechanism of the lever has a first hinge arm pivotable about a horizontal axis, on which a first coupler device is preferably detachably and / or replaceably fixed or fixable. For this purpose, according to an embodiment of the lever according to the invention, the first hinge arm has an interface region through which the coupler head of the automatic coupler is replaceably fixed to the first hinge arm.

[0019] Relatedly, for example, it can be considered that the interface area has at least one housing device. The interface area is essentially used for detachably and mechanically connecting the first hinge arm of the pull rod to the support structure of the coupler head, especially the support structure of the coupler head of the automatic coupler.

[0020] In particular, this modular or modular construction of the coupler arrangement structure is achieved in this way, the coupler device mainly consisting of a tie rod and a separately designed coupler head. Because the first hinged arm of the tie rod can be connected to different coupler heads through the interface area, the coupler arrangement structure according to the invention is suitable for coupling with vehicles with different structural types or different kinds of couplers, especially coupler arrangements that do not require modification or replacement of the hooks of shunting vehicles. Therefore, the solution according to the invention can accomplish various shunting tasks, making it an extremely flexible system overall.

[0021] To simplify the replacement of the coupler head, according to an embodiment of the solution of the present invention, the pull rod has an interface area through which the first hinge arm of the pull rod is detachably mechanically or connectably connected to the support structure of the coupler head.

[0022] Different implementations can be considered for the interface area. It is particularly suitable here for the interface area to have at least one housing device. However, as a supplement or alternative, the interface area may also have at least one latch device with at least one pull pin (German: Absteckbolzen).

[0023] According to an embodiment of the pull rod of the invention, the hinge device of the pull rod has a second hinge arm pivotable about a horizontal axis, on which a coupler device, in particular a pull ring and a pull ring compatible with threaded couplings for shunting vehicles, is fixed or can be fixed. Preferably, the second hinge arm is connected to the first hinge arm of the pull rod in such a way that the two hinge arms pivot together, and in particular only together, about the horizontal axis.

[0024] The second hinge arm is preferably connected to the first hinge arm in such a way that the two hinge arms pivot together, and in particular only together, about a horizontal axis, wherein an angle of 80° to 100°, preferably approximately 90°, is opened between the first and second hinge arms.

[0025] With an advantageous extended design, the operating device is fixed to the tie rod above the horizontal coupler plane. Depending on the position of the automatic coupler, its locking position in the coupler plane, and the design of the operating device, it is thus not subject to the gravitational load of a single coupler assembly.

[0026] In one extended design, at least one drive unit acts at least indirectly on a rocker arm that is anti-transmittally connected to a horizontally hinged axis to form a drive unit / rocker arm unit. In a particularly advantageous design, the drive unit acts directly on the rocker arm. In this case, the transmission of the required torque is achieved directly without additional conversion. The operating device is characterized by requiring a minimum number of components.

[0027] To ensure uniform load distribution during pivoting out and pivoting in, and to maintain a small and compact design for the operating equipment, it includes drive / rocker units arranged on both sides of a reference tie rod. The latter can thus be constructed to be significantly smaller, and the structural space freed up can be used for other purposes.

[0028] In a particularly advantageous extended design, a single drive unit is designed as a hydraulic or pneumatic linear motor, which is fixed to a support device arranged on a tie rod. The preferred use of a pneumatic linear motor offers the advantage that it eliminates the need for an additional energy source for these drives; instead, they can be integrated into or connected to the existing compressed air system of the rail vehicle.

[0029] Advantageously, a single hydraulic or pneumatic linear motor, or a lifting piston / cylinder unit designed for bilateral action, or a lifting piston / cylinder unit designed for unilateral action with a reset device, particularly a reset spring. In the first case, different functional positions can be achieved by loading and venting individual pressure chambers; in the second case, the reset force is preset.

[0030] Structurally, the bracket is preferably formed from a sheet metal member, particularly a profile component, fixed to a tie rod. This fixing can be achieved through a force-fit connection, a form-fit connection, or preferably a material-joint connection. The bracket provides a housing for the drive mechanism, preferably designed as a lifting piston / cylinder unit with a connector for connection to a compressed air supply system. Preferably, the lifting piston / cylinder unit includes a device for controlling the loading of individual connectors, in its simplest form, a valve device.

[0031] Several feasible designs exist for the anti-transmission single connection between the articulation device and the coupler head and / or between the articulation device and the rocker arm. Advantageously, form-fit connections are used. These can be designed, in particular, as keyway-connectors or hydraulic connections.

[0032] In another embodiment, the anti-transmission connection between the hinge and the coupler head and / or the anti-transmission connection between the hinge and the rocker arm can be designed as a force-fit connection.

[0033] In a particularly advantageous manner, the drive unit / rocker unit is arranged and designed such that the piston of the lifting piston / cylinder unit is unloaded in the position where the automatic coupler device pivots into the coupler plane.

[0034] According to an advantageous design, at least one locking device is also provided, which enables the unloading of the drive device when the first coupler device is in the pivoted position.

[0035] Furthermore, there is an advantageous possibility of locking in the pivot position.

[0036] In terms of collision safety, it is generally advantageous to integrate energy-dissipating and / or damping elements into the tie rod of the transition coupler to reduce the tensile and / or compressive forces transmitted through the tie rod during driving. The energy-dissipating and / or damping elements are preferably regenerative, for example, designed as spring devices or spring assemblies. Alternatively, the use of destructive-designed energy-dissipating elements, or a combination of destructive and regenerative components, can also be considered. Attached Figure Description

[0044] Figure 1A highly simplified schematic diagram illustrates the basic structure of the coupler arrangement 100 according to the invention, which is in the form of a transition coupler or a hybrid coupler. It includes a tie rod 1 and at least one first coupler device 20 in the form of an automatic coupler 21 pivotally supported on the tie rod 1 about a horizontal geometric axis A. Furthermore, a second coupler device 30 is provided.

[0045] The tie rod 1 has a first end region 2 on the side of the carriage, through which it is preferably detachably connected to the carriage, particularly the carriage or chassis of a freight or shunting vehicle. Furthermore, the tie rod 1 has a second end region 3 opposite to the first end region 2. A hinge device 4 is provided on this second end region 3 to pivot the coupler head 22 of the first coupler device 20, particularly the automatic coupler 21, into the horizontal coupler plane KE as needed. The hinge device 4 includes at least one pin 5, horizontally viewed from the mounting bearing on the vehicle, in relation to the coupler arrangement. It is rotatably supported in a through-hole in the forked end region 3 of the tie rod 1. This pivoting occurs about a horizontal axis A, which corresponds to the geometric axis of the pin 5 and is horizontal in this position, and therefore corresponds to the hinge axis GA of the hinge device 4.

[0046] Then, the horizontal coupler plane KE can be described by the longitudinal axis of the tie rod 1 and the vertical line perpendicular to it in the horizontal direction when viewed from the installation position on the rail vehicle, especially the horizontal axis of the pin 5 or the hinge axis GA of the hinge device.

[0047] The first coupler device 20, and in particular the coupler head 22 of the automatic coupler 21 (not shown in detail here), is connected to the hinge device 4 in a non-transmissionable manner. This can be achieved by an integral design of the coupler head 22 and the hinge device 4, in particular the pin 5, or preferably by a detachable connection thereto.

[0048] Figure 1 A first coupler device 20 is shown in the horizontal coupler plane KE. An operating device 6 is provided to enable the first coupler device 20 to pivot in or out of the horizontal coupler plane KE. The operating device 6 is directly fixed to the pull rod 1 and includes at least one drive device 12 that acts eccentrically relative to the horizontal hinge axis GA or is designed on the hinge device 4 to pivot the coupler head 22 of the automatic coupler in or out of the horizontal coupler plane KE as needed.

[0049] Operating device 6, particularly the individual drive unit 12, is fixed to the pull rod 1 above the horizontal coupler plane KE. This fixing occurs, for example, on a bracket 17 connected to the pull rod 1. The bracket can be detachably or non-detachably connected to the pull rod. The drive unit 12 acts at least indirectly on a rocker arm 13, which is anti-transmittedly connected to the horizontal hinge axis GA, to form a drive unit / rocker arm unit 14. In the illustrated case, the output end 16 of the drive unit 12 is coupled to the rocker arm 13 via a hinged connection 15. Depending on the design of the rocker arm 13, the coupling of the drive unit 12 occurs above or below the hinge axis GA when the first coupler device 20 is pivoted into the coupler plane KE.

[0050] Viewed longitudinally from the tie rod 1, the position of the hinge axis GA and the connection or fixation of the drive device 12 on the tie rod 1 are spaced apart from each other. The hinge on the rocker arm 13 is preferably made in the circumferential direction of the hinge axis GA such that the force direction of the drive device used to introduce torque on the rocker arm 13 coincides with the pivoting direction.

[0051] The drive unit 12 is preferably designed as a pneumatic linear motor. Figure 1 An example of a pneumatic linear motor designed as a two-sided lifting piston / cylinder unit 18 is shown. It has at least two joints 19.1, 19.2, which are coupled to different pressure chambers in the cylinder to load different piston faces. The pressure chambers can be coupled to a pressure medium supply device 25, which can be formed by the pressure medium system of a rail vehicle. To control the pressure medium supply to the lifting piston / cylinder unit 18, a device for controlling the pressure medium supply is provided in the connection between the joints 19.1, 19.2 on the cylinder and the pressure medium supply system; this device is designed in the simplest case as a valve device.

[0052] The second coupler device 30 can be designed in various ways. It is preferably formed of a pull ring 10, which can work in conjunction with a hook (not shown here).

[0053] The second coupler device 30 pivots into the coupler plane when or after the first coupler device 20 pivots out of the coupler plane. For this purpose, the second coupler device 30 is preferably also pivotally supported about the hinge axis GA. This support is preferably directly on the hinge device 4 and is carried out such that the two coupler devices 20 and 30 are arranged at a predefined angle to each other, preferably approximately 90°, and their pivoting is always forced into coupling.

[0054] First coupler device 20 Figure 1 The position shown here corresponds to position I in the horizontal coupler plane KE. The direction of movement of the piston around the hinge axis GA and the drive unit 12 is indicated by arrows.

[0055] Figure 2 Example of pressing Figure 1 The coupler arrangement structure 100 is advantageously designed in the pivot position II of the coupler device 20, particularly in the pivot position of the coupler head 22 of the automatic coupler 21. To illustrate the operating equipment more clearly, Figure 3b This position is shown without the coupler head 22, while Figure 3a The pivoting position I is shown without the coupler head 22. Identical components use the same reference numerals.

[0056] The hinge device 4 has a first hinge arm 7 that is pivotable about a horizontal axis, particularly the hinge axis GA, on which the coupler head 22 of the automatic coupler 21 is detachably and / or replaceably fixed or can be fixed. The coupler head 22 is detachably connected to the hinge device 4 via an interface region 9. In the illustrated case, this is achieved via a housing connection device.

[0057] According to an advantageous embodiment of the coupler arrangement structure 100 of the present invention, the coupling lock associated with the coupler head 22 is designed to be particularly compatible with the coupler head, in a funnel / cone structure, such as type 10, type 35, type 330, type 430, type 55, or type 140. However, other coupler head types or coupler head structure types are also contemplated, such as wedge-lock type coupler heads, BSI type coupler heads, or GF type coupler heads.

[0058] In addition, Figure 2 As specified in the pull rod 1 shown, the hinge device 4 also has a second hinge arm 8 that is pivotable about a horizontal axis, on which a second coupler device 30 is fixed or can be fixed, in particular a pull ring 10, such as a pull ring 10 compatible with a threaded coupling, so that it can be coupled to the coupler arrangement structure 100 or to a threaded coupling.

[0059] In this case, the second hinge arm 8 is connected to the first hinge arm 7 of the hinge device 4 in such a way that the two hinge arms 7, 8 pivot together only about the horizontal hinge axis GA.

[0060] Between the first hinge arm 7 and the second hinge arm 8, there is an angle of 80° to 100°, approximately 90°, that is, the two coupler devices 20, 30 are forcibly coupled to each other in terms of pivoting motion.

[0061] Two hinged arms 7, 8 are pivotally supported by a horizontally extending pin 5, which is part of the hinge device 4 and defines the pivot axis GA of the hinge device 4. Figuratively speaking, the horizontally extending pin 5 functions similarly to the pull pin of a threaded coupling.

[0062] In order to pivot the coupler head 22 of the automatic coupler 21, the operating device 6 has drive / rocker units 14 arranged on both sides of the reference rod 1 to pivot into or out of the horizontal coupler plane KE as needed. They are fixed to the bracket 17 in series on the rod 1.

[0063] To explain more clearly, Figure 3a and 3b Show press Figure 2 The coupler arrangement structure 100 is in two functional positions, namely pivoting into the coupler plane KE ( Figure 3a The position of ) and pivot out of the coupler plane KE ( Figure 3b This is an embodiment where the coupler head 22 without the automatic coupler 21 is located. Only the interface region 9 is visible on the first hinge arm 7, through which the coupler head 22 of the automatic coupler can be interchangeably fixed to the first hinge arm 7. The interface region 9 preferably has at least one housing device.

[0064] The articulation device 4 includes a horizontally extending pin 5, which defines the pivot axis for the first articulated arm 7 and a pull ring 10 compatible with the pull hook of a threaded coupling, wherein the horizontally extending pin 5 is specifically designed as a pull pin for the threaded coupling. The pin 5 is either integrally designed with the individual articulated arms 7, 8, or connected to the individual articulated arms 7, 8 in a non-transmission manner. Non-transmission connections can be designed differently. Force-fit connections and form-fit connections are both possible.

[0065] The individual rocker arm 13 of the drive unit / rocker unit 14 is connected to the pin 5, especially its end region, in a transmission-resistant manner. This connection can be achieved by force-fit or form-fit.

[0066] In the case shown, the pin 5 is rotatably supported in the through hole of the forked end region 3 of the pull rod 1, and the rocker arm 13 is fixed thereon in the end region of the pin 5 that protrudes from the through hole.

[0067] A single drive unit 12 is designed as a lifting piston / cylinder unit 18 and functions as a pneumatic linear motor. A single cylinder is fixed to a bracket 17 for this purpose. The piston and rocker arm 13 are preferably hinged. The connection is indicated by 15 and is implemented eccentrically relative to the hinge axis GA. During extension or retraction, the piston generates torque about the hinge axis GA.

[0068] The individual drive unit 12 is preferably fixed directly to the bracket 17. In its simplest form, the bracket 17 is formed of a T-plate with a housing or housing device for the cylinder. The bracket 17 and the housing device may be formed as separate components, or in alternative embodiments they may be integrally formed in a single component, such as in a plate component.

[0069] exist Figure 3a In position I shown, 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 fixes the first coupler device in the coupler plane KE at a position opposite to the end region 3 of the pull rod 1.

[0070] exist Figure 3b In position II shown, the first coupler device 20 pivots out of the coupler plane KE and the second coupler device 30 pivots into the coupler plane KE. The piston of the drive unit 12, in particular the lifting piston / cylinder unit 18, extends in this position.

[0071] Figures 1 to 3b An advantageous design of the coupler arrangement 100 is shown, wherein the coupler head 22 of the automatic coupler 21 pivots upward and the piston of the lifting piston / cylinder unit is in a retracted state in the pivoted-in position I. For this purpose, the drive unit 12 is hinged to the rocker arm 13 below the hinge axis GA.

[0072] Pneumatic lifting piston / cylinder unit 18 according to the press Figure 5a The implementation is designed as a lifting piston / cylinder unit 18 acting on both sides or as follows: Figure 5b Designed as a single-sided lifting piston / cylinder unit 18. Figure 5a In its simplest form, the cylinder has two pressure chambers, which can be filled with pressure medium or vented through corresponding connectors 19.1 and 19.2.

[0073] according to Figure 5b Only one of the pressure chambers is loaded, and reset is achieved by spring force.

[0074] Figure 4 An example is shown of a transmission-resistant connection 26 between the pin 5 and thus the hinged device 4 and the first coupler device 20. In the case shown, this connection is designed as a form-fitting device and is a key / groove connection.
