Description

The invention relates to a rail vehicle structure, in particular with the features according to the preamble of claim 1. The invention relates in particular to a rail vehicle structure defining an installation space for receiving a pulling and pushing device. The invention further relates to a pulling and pushing device and a coupling, in particular a pulling coupling for mechanically connecting two rail vehicles.

Couplings in the form of train couplings for mechanically connecting two rail vehicles, especially freight cars, are characterized by the arrangement of pulling and impact devices in the UIC-503-1 installation space. The pulling and pushing device is characterized by a coupling-side interface for coupling to a coupling shaft. The coupling shaft is either integrally formed with a coupling head carrying the coupling elements or connected to it. For this purpose, the pulling and pushing device is lifted from below into a coupling installation space provided on the rail vehicle structure, in particular the base frame, and secured against it from falling down with a fastening plate. The connection to the coupling shaft is realized via a coupling shaft bolt, which is also inserted from below into the connection area of the coupling shaft and the pulling and pushing device and is secured via a separate holding plate that can be connected to the components delimiting the installation space.

In addition to this embodiment, holding plates with an opening for inserting the coupling shaft bolt are also known, with the coupling shaft bolt being secured by closing the opening with a separate cover-shaped element and screwing it to the holding plate. Other versions provide for a safety device integrated in the housing of the pulling and pushing device to secure the coupling shaft bolt.

In all known designs, the coupling shaft bolt is inserted in the vertical direction from below into the connection area in the installation space, ideally inserted with an auxiliary tool with an extension and then the safety device is installed. The difficulty lies in removing the auxiliary tool and securing the coupling shaft bolt against the weight of the coupling shaft bolt. The coupling shaft bolt is then partially held manually with the help of a second person, with a significant risk of accidents due to the coupling shaft bolt accidentally falling or the fingers becoming trapped. This applies to both new assembly and replacement or conversion of coupling types.

The object of the invention is to further develop a safety device for a pulling and pushing device and the connection area, in particular the connection between a coupling shaft and the pulling and pushing device of a coupling of a rail-bound vehicle, in such a way that quick and easy assembly is possible without the use of Aids can be carried out by just one person while avoiding the risk of accidents.

The object is achieved according to the invention by an embodiment in accordance with the independent claims. Further advantageous embodiments of the present invention can be found in the subclaims.

• an installation space extending in the longitudinal direction of the rail vehicle structure and at least partially open in the vertical direction downwards for receiving a pulling and pushing device with an interface for connecting the pulling and pushing device to a coupling shaft of a coupling that can be arranged on the rail vehicle structure via a in the vertical direction via the Opening into the installation space and defined by the arrangement of the interface and referred to as the connection area, a portion of the installation space that can be brought into operative connection to form a connection; coupling shaft bolts;
• a safety device assigned at least to the connection area and attachable to the rail vehicle structure for supporting and securing the pulling and pushing device and, when connected, in the vertical direction relative to the rail vehicle structure;

is characterized in that the securing device comprises a support structure which can be pivoted between a first and second position about a geometric pivot axis arranged outside the connection area and which forms a contact surface for the coupling bolt, which is designed and arranged in such a way that it is suitable for access to the in the first position To release the connection area into the installation space, in the second position to close the connection area in the vertical direction downwards while supporting the connection when it is in the vertical direction and when pivoting between the first and second positions to support the coupling shaft bolt when inserting it into the installation space.

The term rail vehicle structure stands for any structure consisting of one or more components or assemblies which define or limit the installation space mentioned for receiving and in particular storing the pulling and pushing device as well as the connection area with a coupling shaft of a coupling and parts of the coupling shaft. The rail vehicle structure can be a vehicle underframe, in particular a car body or a portion thereof. The definition or limitation of the installation space is carried out in particular by components, in particular frame components, supports, etc.

The term installation space is used in particular for the required arrangement area of the coupling components on the vehicle structure to be provided for the storage/articulation of the coupling on this. Specifically, installation space is understood to mean the space defined in accordance with UIC-503-1. This is defined by corresponding interfaces between the coupling and the coupling components and the rail vehicle structure and is therefore not to be understood as a necessarily closed space, ie with closed wall areas. The Limits of the installation space are defined in particular by the rail vehicle structure, its support structure made up of longitudinal and cross beams.

A traction and impact device is understood to mean, in particular, a device which is suitable for transmitting traction and impact forces and for dampening traction and pressure impacts.

Coupling is understood to mean, in particular, a device for mechanically connecting with a complementary counter-coupling between two adjacently arranged rail vehicles.

Geometric swivel axis means the geometrically conceived axis, realized or realizable using components of various designs, around which the swivel movement takes place.

The solution according to the invention of using a pivotable support structure for at least indirectly supporting the connection between a pulling and pushing device and a coupling shaft, in particular the coupling shaft bolt, offers several advantages. The pivotable support structure provides easy-to-handle and safe assembly support without the need for additional tools. In particular, when inserting the coupling shaft bolt, it can be guided in a supported manner when the support structure is pivoted and positioned in the connection area of the installation space, in particular for the connection between the coupling shaft and the pulling and pushing device via the support structure. Hand guiding and holding is no longer necessary, which also significantly minimizes the risk of accidents.

Furthermore, this solution also allows tension and push devices to be pre-equipped in the installation space, especially if it is a standard installation space in accordance with the UIC standard, for example if you intend to later convert to a different type of coupling without necessarily already having a connection to the current one the type of coupling provided on the rail vehicle structure. The pre-equipment can be done at a different time to the actual conversion, although the conversion is relatively easy by moving the support structure into the first position and introducing the coupling shaft bolt to connect the interface of the pulling and pushing device with the coupling shaft of the coupling type to be retrofitted by pivoting the support structure and securing the support structure relative to the rail vehicle structure.

Furthermore, the solution according to the invention also allows simple subsequent conversion, since the coupling shaft bolt can be easily removed and the connection at the interface can therefore be easily broken and re-established.

In order to be able to guide the coupling shaft bolt safely and position it in the connecting position until the support structure is completely secured in the second position, the support structure, in an advantageous development, has a device, in particular a one-hand actuation device, on its side facing away from the installation space in the second position, which is arranged and is designed to be able to pivot and hold the support structure between the positions with one hand.

In a first embodiment, the one-handed actuation device is formed integrally by geometric shaping on the support structure or is permanently connected to it, for example by welding. This solution offers the advantage that the one-hand actuation device is arranged captively on the support structure.

In a second embodiment of the one-hand actuation device, it can also be designed to be detachably connectable to the support structure. In this case, such a device does not have to be provided for every coupling device, but a standard tool can be provided for standardized connection devices between the support structure and the one-hand actuation device.

There are a number of possibilities with regard to the connection of the support structure and in particular the arrangement of the geometric pivot axis. However, the pivot axis must be provided outside the connection area and thus the arrangement area of the coupling shaft bolt axis in the connected state in order to create a leverage effect on the coupling shaft bolt can. The arrangement is preferably carried out in the longitudinal direction of the rail vehicle structure and thus in the direction of extension of the installation space when viewed in the installed position of the pulling and pushing device, spaced on the rail vehicle structure side from the connection area or in other words in the area of the extension of the pulling and pushing device in the longitudinal direction downstream of the connection area. For this purpose, the pivot axis is arranged to run perpendicular to the longitudinal direction in a horizontal plane. The actuation during pivoting can therefore easily be carried out from both sides of the rail vehicle structure.

In a first variant, the geometric pivot axis arranged outside the connection area can be arranged on the pulling and pushing device, in particular a housing or housing component of the pulling and pushing device, with the connection between the support structure and the rail vehicle structure in position II allowing a relative movement in the longitudinal direction Connection is formed. In this case, the pulling and pushing device can already be pre-assembled and delivered with the support structure as a structural unit. The pivot axis is preferably arranged on a lower housing part in the installed position, in particular the lower flange of the housing of the pulling and pushing device.

In a second particularly advantageous variant, the geometric pivot axis arranged outside the connection area is arranged on the rail vehicle structure itself or on a component firmly connected to it. For differently designed pulling and impact devices, standardized support structures with correspondingly standardized connection areas on the support structure and the rail vehicle structure can be provided.

In a first particularly advantageous embodiment, the support structure of the securing device has a storage area for pivotable storage in order to fulfill the functions described, a first support area for supporting the connection, in particular the coupling shaft bolt, and a fastening area for at least indirectly fastening and securing the support structure to the rail vehicle structure. The safety device further has at least one further second support area for supporting the tensile and Shock device on. In a first particularly advantageous embodiment, the first support area and the second support area are formed by different components. This means that the functions of holding and securing the pulling and pushing device and the coupling shaft bolt are safely separated from each other. This is particularly advantageous if the pulling and pushing device is to be left in the installation space and only a different type of coupling is to be connected to it. In a particularly advantageous embodiment of this first embodiment, the safety device comprises a holding plate which forms the second support area and covers the downwardly open installation space in the connection area and in the longitudinal direction, which is attached to a component of the rail vehicle structure that delimits the installation space. Fastening is preferably done via screw connections. The holding plate has an opening to the connection area. The holding plate secures the pulling and pushing device securely from falling, but not a coupling shaft bolt that may be provided in the connection area. For this purpose, the support structure is coupled to the holding plate. In particular, this comprises a shaft bolt securing plate forming the first support area, which is mounted on the holding plate so as to be pivotable between two positions about a geometric pivot axis oriented transversely to the longitudinal direction of the installation space in such a way that the shaft bolt securing plate releases the opening on the holding plate in the first position and in the second Position the opening on the holding plate releasing the connection area closes downwards in the vertical direction, with connecting devices for connecting the shaft securing plate to the holding plate in the second position being provided on the holding plate and the shaft bolt securing plate. The connecting devices can be designed and arranged in such a way that a positive or non-positive connection can be achieved between the shaft securing plate and the holding plate. Preferably, a simple connection is realized using a securing or locking bolt. For this purpose, the holding plate has two through-opening-carrying, protruding and spaced-apart regions between which the fastening region of the support structure can be moved in the second position, the fastening region having a through-opening which is in the second Position with the through openings of the protruding areas on the holding plate assumes an aligned position for receiving a locking pin.

In an alternative second embodiment, the pivotable mounting is not on the holding plate, but on the pulling and pushing device and the attachment is also on this.

In a second embodiment, the two support areas are formed on one component. In particular, the support area is formed on the support structure for supporting and carrying the pulling and pushing device. The storage area, the first support area and the second support area and the fastening area are formed on a component, in particular a plate-shaped element, with the plate-shaped element in a first end area in a first variant on the pulling and pushing device, in particular in the installed position of the pulling device. and impact device viewed in the installation space, the lower housing component of the pulling and impact device is pivotally mounted on this and the fastening area has connecting devices for fastening to a component delimiting the installation space, in particular the vehicle underframe.

In a preferred second variant of the second embodiment, the storage area, the first support area and the second support area and the fastening area are formed on a component, in particular a plate-shaped element, the plate-shaped element being in a first end area on a component which delimits the installation space in the vertical direction downwards is pivotally mounted and the fastening area has connecting devices for fastening to a component delimiting the installation space, in particular the vehicle underframe.

Another second solution approach is to separate the function of securing the coupling shaft bolt from securing or holding the pulling and pushing device and to provide the securing of the coupling shaft bolt in the vertical direction only on the pulling and pushing device. In this case, the function of securing the coupling shaft bolt on the pulling and pushing device can already be provided pre-assembled. According to claim 14, the pulling and pushing device a train coupling that can be arranged on a rail vehicle structure and is equipped with an interface for connecting the pulling and pushing device with a coupling shaft of the pulling coupling, the interface comprising at least one opening oriented perpendicular to the longitudinal direction of the pulling and pushing device for receiving a coupling shaft bolt that can be inserted at the interface. The pulling and pushing device is designed in such a way that it comprises a support structure forming a first support area for supporting the coupling shaft bolt, which is movably mounted on the housing of the pulling and pushing device between a first position releasing the interface and a second position covering the interface, wherein the support structure can be secured in the second position. The securing takes place directly opposite the pulling and pushing device. The pulling and pushing device generally comprises at least one or more energy dissipation devices, which are guided or mounted in a support structure called a housing. The arrangement and storage of the support structure is preferably carried out on a housing part which points vertically downwards in the installed position in the rail vehicle structure.

In a first variant of this further approach, the support structure is mounted in a pivot axis on the housing about a pivot axis arranged outside the interface transversely to the longitudinal direction for pivoting between the first and second positions. In a second variant, the support structure is mounted on the pulling and pushing device so that it can be displaced in the longitudinal direction. In an advantageous development of the two variants, the support structure is secured, in particular in the longitudinal direction of the pulling and pushing device, preferably in a form-fitting and/or non-positive manner on the housing of the pulling and pushing device, in particular it can be clamped relative to it in the second position or can be fastened to it .

According to a particularly advantageous embodiment of the second variant of the second approach, the support structure comprises a plate-shaped element, which is guided displaceably in a guide on the housing which forms a stop in the second position on one side in the longitudinal direction and holds the plate-shaped element perpendicular to the longitudinal direction and which determines the position of the plate-shaped element in the second position is held via securing elements, in particular a locking bolt which secures the plate-shaped element in the second position and can be fastened to the housing of the pulling and pushing device.

For a rail vehicle structure with an installation space extending in the longitudinal direction of the rail vehicle structure and at least partially open in the vertical direction downwards for receiving such a pulling and pushing device according to the second approach with an interface for connecting the pulling and pushing device to a coupling shaft on the rail vehicle structure The coupling shaft bolt that can be arranged via a coupling shaft bolt that can be introduced into the installation space in the vertical direction via the opening and is defined by the arrangement of the interface and is referred to as the connection area and is called the connection area, the securing device includes, in addition to the support structure provided on the pulling and pushing device, for the coupling shaft bolt for supporting and securing the pulling and pushing device then a holding plate that can be assigned to the installation space in the arrangement area of the pulling and pushing device and can be fastened to the rail vehicle structure.

The above-mentioned approaches according to the invention are of considerable advantage for any pre-installation of traction and impact devices in a rail vehicle structure, in which the completion to a train coupling, in particular a central buffer coupling, takes place with a time offset. In particular, if the connection between a coupling shaft, which has an interface at its free end for connecting to an interface of a pulling and pushing device arranged in the installation space of a rail vehicle structure, can be made very quickly, easily and without the risk of injury due to holding with the solutions according to the invention of the coupling shaft bolt, the connection between the coupling shaft and the cable and impact device can be established and secured.

In the Figures 1a to 1c is a schematically very simplified representation based on a section of a view of a rail vehicle structure 1, in particular a base frame of a car body of a rail-bound vehicle 2, the installation space 3 for arranging and storing a partial area of a coupling 4 for at least mechanically connecting the rail-bound vehicle 2 with a complementary one, not shown Counter-coupling of an adjacent rail-bound vehicle for coupling with this to form a train set. To clarify the individual directions, a coordinate system is created as an example, the direction information for which is retained for the other figures. The X direction defines the longitudinal direction of the coupling 4, which in the installed state is connected to the Longitudinal direction of the individual rail-bound vehicle 4 and thus coincides with the longitudinal direction of the train set formed in this way when coupled with an adjacent rail vehicle. The Y direction describes the width direction and thus the direction perpendicular to this in the transverse direction of the rail-bound vehicle 2. The Z-direction describes the height direction, which coincides with the height direction of the rail-bound vehicle 2 in the installed position of the pulling and pushing device 5.

The installation space 3 preferably corresponds to a space defined according to UIC standard 530-1 and provided on the underframe of the rail-bound vehicle 2 and is in the longitudinal direction of the rail-bound vehicle 2 to accommodate a pulling and pushing device 5 of the coupling 4 and its coupling or connection the remaining coupling components of the coupling 4, which is characterized by further extensions perpendicular to the longitudinal direction, in particular in the width direction and vertical direction. The installation space is defined as free space and is usually not surrounded and limited by a completely closed housing or closed walls, but is limited or defined by components of the rail vehicle structure 1, in particular the base frame. These components are, for example, supports, frame components, traverses, etc. The coupling 4 further comprises a coupling head 4.1 and a coupling shaft 4.2, which can be designed as a separate component or integrally with the coupling head 4.1. Such a pulling and pushing device 5 is viewed in the longitudinal direction with an interface 6 forming a first connection area for connecting to a vehicle-side interface 12 of a coupling shaft 4.2 of the coupling 4 and a second interface 7 arranged at a distance from this for fastening or bracing the pulling and pushing device 5 formed on the vehicle structure 1. The connection 13 of the pulling and pushing device 5 with the coupling shaft 4.2 takes place at the interfaces 12, 6 of the coupling shaft 4.2 and the pulling and pushing device 5 by means of a coupling shaft bolt 9.

The installation space 3 serves to accommodate the pulling and pushing device 5 and its connection 13 with the other coupling components, in particular the coupling shaft 4.2 via a coupling shaft bolt 9 which interacts with the first interface 6 of the pulling and pushing device 5, the center axis of which is arranged in the vertical direction in the installed position . For this purpose, the installation space 3 has a partial area which, in the unloaded and uncoupled state, corresponds to the arrangement area of the connection between the coupling shaft 4.2 and the interface 6 of the pulling and pushing device 5 and is referred to as the connection area 3.1. Coupling shaft 4.2, in particular the interface 12 of the coupling shaft 4.2 and the first interface 6 of the pulling and pushing device 5, have corresponding receiving openings for the coupling shaft bolt 9, which are formed around axes running in the vertical direction and which are arranged in alignment with one another in order to realize the connection 13. The installation space 3 on the vehicle structure 1 is usually designed to be open downwards when viewed in the vertical direction in order to be able to insert the coupling shaft bolt 9 in the vertical direction from below. The coupling shaft bolt 9 and partial areas of the pulling and pushing device 5 are then secured in the vertical direction against falling out by means of appropriate securing devices 15 relative to the rail vehicle structure 1.

According to the invention, to simplify assembly, a securing device 15 is provided in the form of a combined assembly aid and holding device, which provides support when inserting the coupling shaft bolt 9 into the connection area 3.1 in the installation space 3 and securing at least the connection 13, in particular the coupling shaft bolt 9, in the vertical direction against falling out of the installation space 3. For this purpose, the securing device 15 comprises a support structure 10 which can be pivoted between a first and second position I, II about a geometric pivot axis S arranged outside the connection area 3.1 and which forms a first support area 16 with a contact surface 8 for the coupling shaft bolt 9, which is designed and arranged in this way , to be suitable in the first position I to enable access to the connection area 3.1 within the installation space 3 and in the second Position II to close the installation space 3 in the area of the connection area 3.1 in the vertical direction downwards while supporting the connection 13 when it is present in the vertical direction. When pivoting between the first and second positions I, II, the coupling shaft bolt 9 can be supported and guided over the contact surface 8 for insertion into the installation space 3. The safety device 15 further comprises at least one further second support area 17 for supporting the pulling and pushing device 5.

The ones in the Figures 1a to 1c The particularly advantageously designed safety device 15 shown is designed in such a way that the functions of the first and second support areas 16, 17 are separated and are preferably implemented with different components. For this purpose, the safety device 15 comprises a holding plate 18 which forms the second support area 17 and covers the installation space 3, which is open downwards in the vertical direction in the connection area 3.1 and beyond in the longitudinal direction, which is attached to a component of the rail vehicle structure 1 delimiting the installation space 3 and the one Opening 19 for releasing the connection area 3.1. The attachment takes place, for example, on two frame parts, in particular supports, which delimit the installation space 3 and extend in the longitudinal direction of the rail vehicle structure 1. The attachment is preferably carried out releasably via appropriate connecting devices 29, for example screw connections. Other versions are conceivable. The connecting devices 29 are shown in a view from below Figure 1c preferably evenly distributed over the extent of the holding plate in the longitudinal direction on both sides of the connection area 3.1. The side of the holding plate 18 facing the installation space 3 forms in particular a contact surface for supporting the pulling and pushing device 5. The support structure 10 is assigned to the holding plate 18 in such a way that it is suitable with the opening 19 for closing it and, if necessary, for guiding it a coupling shaft bolt 9 to interact with it.

For this purpose, the support structure 10 comprises a shaft bolt securing plate 20 which forms the first support area 16 and which is attached to the holding plate 18 by a transverse direction Extension of the installation space 3 viewed in the longitudinal direction, the geometric pivot axis S is pivotally mounted between two positions I, II in such a way that the shaft bolt securing plate 20 in the first position I releases the opening on the holding plate 18 and in the second position II the opening 19 releasing the connection area on the holding plate 18 closes downwards in the vertical direction. For this purpose, a storage area 22 is provided on the shaft bolt securing plate 20 for pivotally mounting the shaft securing plate 20 relative to the holding plate 18, in which the corresponding devices and means for storage are arranged. The storage is preferably carried out via an articulated connection describing the pivot axis S, in particular a hinge connection on the holding plate 18. The arrangement of the articulated connection, in particular the pivot axis S describing it, takes place outside the connection area 13, preferably viewed in the longitudinal direction of the installation space 3, the connection area 3.1 in the direction of the subordinate to the vehicle. To hold the shaft bolt securing plate 20 in the second position relative to the installation space 3, devices 23 are provided on the holding plate 18 and the shaft bolt securing plate 20 for creating a connection 21 between the shaft securing plate 20 and the holding plate 18 in the second position II. The arrangement of the devices 23 on the shaft securing plate 20 describes a fastening area 24 thereon. The fastening area 24 is arranged at a distance from the storage area 22, in particular offset from one another in the longitudinal direction in the installed position. The devices 23 on the shaft securing plate 20 and the holding plate 18 are arranged upstream of the connection area 3.1 when viewed in the longitudinal direction of the installation space 3.

The connection 21 can be positive or non-positive. In the simplest case, projections with through openings are provided on the holding plate 18 on both sides of the connection area 3.1 and thus on both sides of the opening 19, which are aligned with a through opening in the fastening area 24 of the shaft bolt securing plate 20 in the second position II of the support structure 10 and through which a securing bolt can be inserted to realize one positive connection 21. This type of connection is in the Figures 1a to 1c clarified. Other versions are conceivable.

The Figure 1a illustrates the safety device 15 with support structure 10 in position II Figure 1b shows based on an execution Figure 1a While omitting some components, the functionality for realizing the connection 13. Figure 1c shows the safety device 15 when pivoting between position I and position II in a view from below. The coupling shaft bolt 9 can be seen when it is inserted via the opening of the holding plate 18 into the connection area 3.1 in the installation space 3. The support structure 10 supports the guidance of the coupling shaft bolt 9 with the contact surface 8 when pivoting between positions I and II.

Show the Figures 1a to 1c an embodiment with separate assignment of the first and second support areas 16, 17 on different components illustrates this Figures 2a and 2b an embodiment with integral formation of the support areas 16, 17 of the safety device 15 on a component, preferably in the form of a pivotably mounted plate-shaped element 25. This also has a storage area 22 for pivotable storage about a pivot axis S and a fastening area 24 for fastening to the rail vehicle structure 1 in position II to hold this. First and second support areas 16, 17 are formed by a surface on a plate-shaped element 25. This plate-shaped element corresponds to the shaft bolt securing plate 20, which takes over the function of the holding plate 18 in functional concentration. The pivoting storage is carried out in accordance with Figure 2a on the rail vehicle structure 1, in particular one or more frame elements delimiting the installation space, preferably on the underside of one or two longitudinal beams outside the connection area 3.1, in particular downstream of this in the direction of the rail vehicle structure.

The formation of the connection 21 between the support structure 10 and the rail vehicle structure 1 can be analogous to that in Figures 1a to 1c described. For this purpose, corresponding devices 23 describing a fastening area 24 on the plate-shaped element 25 are provided, which interact with devices 23 on the rail vehicle structure under training the connection 21. Other versions are also conceivable. The fastening area 24 is also arranged at a distance from the storage area 22, in particular offset from one another in the longitudinal direction in the installed position. The devices 23 are arranged in the longitudinal direction of the installation space 3 in position II of the support structure 10 upstream of the connection area 3.1.

The connection 21 can also be made in a positive or non-positive manner. In the simplest case - but here in detail: Figure 2a not shown - on the rail vehicle structure 1, on both sides of the connection area 3.1 and thus on both sides of the downwardly open design of the installation space 3 on the components of the rail vehicle structure 1, in particular supports, projections with through openings are provided, which have a through opening in the fastening area 24 of the plate-shaped element 25 in the second position II of the support structure 10 and through which a securing bolt can be inserted to realize a positive connection 21.

In contrast, shows Figure 2b an alternative arrangement of the pivot axis S on the pulling and pushing device 9, in particular a housing part of this. However, since the pulling and pushing device undergoes deformation during operation and under load and as a result the position of the pivot axis S, viewed in the longitudinal direction, can shift relative to the rail vehicle structure 1, this relative movement must be reflected in the connection 21. This is done by forming one of the through openings of the devices 23 on the rail vehicle structure 1 or on the plate-shaped element 25 that takes over the function of the holding plate 18 as an elongated hole.

In all embodiments, the support structure 10 preferably comprises an operating device 30 arranged on the side facing away from the installation space 3 for manually actuating or pivoting the support structure.

Figures 3a and 3b illustrate an alternative embodiment of an easily detachable support structure 10, although the aspect of assembly support for the Coupling shaft bolt 9 is only partially present. The support structure 10 for securing the coupling shaft bolt 9 is not pivotable here but is displaceable between a first position which releases the connection area 3.1 and a second position which closes it downwards and supports the coupling shaft bolt 9 on the pulling and pushing device 9, in particular a housing part. The Figure 3a shows the support structure 10 in position II and the Figure 3b in position I.

The training of the safety device 15 is analogous to Figure 1 with separation of the functions of supporting the coupling shaft bolt 9 and the pulling and pushing device 5 by means of different components. The security device includes a; a support structure forming a first support area for the coupling shaft bolt, which is arranged and mounted directly on the pulling and pushing device 5. The safety device 15 also includes a holding plate 18 which supports the pulling and pushing device 5 to form a second support area 17 and which covers the installation space 3 in the connection area and beyond towards the bottom. The holding plate 18 is here attached to the rail vehicle structure 1, preferably screwed. The holding plate 18 supports and secures the pulling and pushing device 5 in the vehicle underframe. However, the support structure 10 is displaceably mounted on the pulling and pushing device 5. For this purpose, this is preferably guided in a positive-fitting manner in a groove-shaped geometry on the underside of the housing of the pulling and pushing device 5, which is directed downwards in the installed position. The guide 28 on the pulling and pushing device supports the support structure 10 and thus the bolt lock in the vertical loading direction. The guide 28 is also designed with a stop for the support structure 10 that is effective on one side in the longitudinal direction. The guide 28 is particularly advantageously formed at least partially, preferably completely, integrally on the housing of the pulling and pushing device. This can be formed on or off. In the case shown, the guide 28 comprises two areas which, viewed in the longitudinal direction of the pulling and pushing device 5, are arranged on both sides of the first interface 6 on the housing. The first area forms at least one area for axial guidance on the housing, the second area, which in the case shown is in the installed position of the first interface 6 of the pulling and pushing device 5 is arranged upstream, forms not only a guide area but also a stop for positioning the support structure 10 in the second position II covering the interface 6.

It would also be conceivable to form the stop from a separate component that can be arranged on the housing of the pulling and pushing device.

The support structure 10 includes a plate-shaped element 27 in the form of a locking plate. The locking plate is held in the second position II via a locking bolt 31, which is arranged transversely to the loading direction. For this purpose, an L-shaped fold of the locking plate is designed as a support geometry and system for the locking pin 31. In the second position, the locking plate lies in the second guide area of the guide 28 against the axial stop formed by it and is held in this position by the arrangement of the branch bolt behind the fold, preferably clamped between the second guide area and the locking bolt. Holding in the second position II can also take place with play, i.e. still permissible axial mobility of the locking plate in the longitudinal direction within a predefined tolerance range. What is important is that secure support of the coupling shaft bolt 9 is possible in the second position II. A screw lock or a combination of positive and frictional locking is also conceivable for securing the support structure 10 to the housing of the pulling and pushing device 5.

1. 1) Kupplungsschaftbolzen 9 in Verbindungsbereich 3.1 im Einbauraum positionieren
2. 2) Stützstruktur 10, insbesondere Sicherungsblech 27 axial in Position II verschieben und Kupplungsschaftbolzen 9 in Einbaulage sichern
3. 3) mit Quer- bzw. Absteckbolzen Stützstruktur 10, insbesondere Sicherungsblech formschlüssig gegenüber Gehäuse der Zug- und Stoßeinrichtung 5 sichern.

The design of the bolt lock is designed to be operated with one hand, making it easier to install the coupling shaft bolt. After it has been positioned in the connection area 3.1 and in operative connection with the interfaces 6 and 12 of the pulling and pushing device 5 and coupling shaft 9, the coupling shaft bolt 9 is held in its position II by moving the locking plate and no longer needs to be held against the weight by hand become. Installation takes place in the following steps:

1. 1) Position the coupling shaft bolt 9 in the connection area 3.1 in the installation space
2. 2) Move the support structure 10, in particular the locking plate 27, axially into position II and secure the coupling shaft bolt 9 in the installed position
3. 3) Secure the support structure 10, in particular the locking plate, with a cross or locking bolt in a form-fitting manner against the housing of the pulling and pushing device 5.

The holding plate 18 is then mounted.

The removal takes place in the reverse order.

The pulling and pushing device 5 can be designed in a variety of ways in all the embodiments shown in the figures, but includes at least a support structure 11 and at least one or more energy dissipation devices 14, which are at least indirectly arranged or aligned thereon. There are a number of options regarding the design, arrangement and mode of operation of the individual or multiple energy consumption devices. The training takes place depending on the specific operational requirements. With regard to their structural arrangement, the individual energy consumption devices can be arranged in series one after the other or parallel to one another. Furthermore, the individual energy dissipation devices can each be designed to be effective in only one direction of force action - tensile force direction or impact force direction or in both directions. The effectiveness of providing several energy consumption devices can occur in series, with a time delay one after the other or in parallel. The energy dissipation devices can be spring devices, in particular spring assemblies, hydraulic damping devices, in particular hydrostatic damping devices, deformation tubes, etc. The pulling and pushing device can have 5 energy dissipation devices of the same type with the same or different design or different types and/or designs.

The energy consumption can contain reversible or irreversible energy consumption areas.
