    Arrangement for deflecting a central buffer coupling of a rail vehicle which has been severed due to the failure of an overload protection in the event of a collision
    TECHNICAL FIELD The invention relates to an arrangement for redirecting a central buffer coupling of a rail vehicle which has been severed due to the failure of an overload safety device in the course of a collision. 15
    State of the art
    Modern passenger rail vehicles are frontally equipped with energy-consuming, so-called crash elements, which dissipate a significant portion of the kinetic energy in a frontal collision and thereby cause lower forces acting on the passengers and the car body forces and thus reduce the risk of injury to passengers. In a frontal collision with a 26 other rail vehicle, it comes first to a
    Clash of clutches. These clutches are often designed as a central buffer coupling, especially in local transport vehicles, trams and subways, usually these clutches contain shock-absorbing 30 and / or resilient elements that absorb, while shortening in the longitudinal direction, at least part of the impact energy. If the energy dissipation in the clutches is not sufficient, which is the case with higher collision speeds between the vehicles, then 36 crash elements (deformation elements) should then come into effect. This 16/06/2011 10:52 1 No .: R235 P.004 / 026 16.Jun.Z011 10:20 051 * 7015 * 601 CI CP / 0635 P.005 / 026 201109785 is sought, the remaining kinetic energy in Build the crash elements and pay special attention not to generate parallel load paths by force transmission in unsuitable places 2u, since so inadmissibly high forces can occur at 5 certain points of the vehicle structure and also increase the accelerations acting on the passengers. Therefore, it is often provided that the clutch in a collision, which is 2i energiereich to be sprung over the shock-absorbing and / or resilient elements of the clutch 10 is separated via a desired shear point from the car body and no longer participates in the further deformation course. This presupposes that in the direction of the center of the car there is sufficient space in which the sheared coupling can escape, this space is not available, for example because others
    Vehicle components are mounted at this point, such a crash-proof coupling connection with a shear-off coupling can not be used meaningfully. 20 Presentation of the invention
    The invention is therefore based on the object of specifying a coupling connection for a shear-off coupling for a rail vehicle, which does not have sufficient axial clearance in the direction of the middle of the carriage for receiving the sheared coupling.
    The object is achieved by an arrangement having the features of claim 1 and a railroad vehicle according to claim 7 30. Advantageous embodiments are the subject of the subordinate claims. 16/06/2011 10:52 2 No .: R235 P.005 / 026 16.Jun.20U 10:20 0S1707S4601 CIC_P * 0635 P. 006/026 201109785
    The basic idea of the invention is an arrangement for deflecting a severed by the failure of an overload fuse in the course of a collision middle buffer coupling of a rail vehicle, comprising a clutch plate and a 5 attached to this clutch plate coupling holder described, wherein a recess is provided in the clutch plate, through which a Clutch passes after the failure of an overload protection, behind which recess a shearing plate is arranged, which with the coupling holder and the coupling plate by means of
    Connecting elements is connected and wherein the recess urging through the coupling separates the connecting elements, wherein the shearing plate and the coupling holder are free to move. By this free mobility, which is limited only by the size and shape of the recess in the coupling plate, the direction of movement of the disconnected coupling is deflected, in particular downwards (in the direction of the track bed). 20 The advantage can be achieved, even in confined spaces
    Space conditions which do not allow a purely axial (in the longitudinal direction of the rail vehicles) moving direction of the separated clutch in a clutch to ensure separation of the clutch, in particular 25, the disconnected coupling does not generate a parallel load path and thus the crash elements can act optimally.
    According to the invention, a shearing plate is provided, which is arranged behind (in the direction of the carriage center) of a coupling plate (to which the coupling is fastened). The coupling plate has a recess in the region of the shearing plate, which is designed so that the sheared coupling can pass through the recess and 16/06/2011 10:53 3 Nr .: R235 P.006 / 026 16.Jun. 20ll 10:21 05170754601 CIC_P £ 0635 P.007 / 026 201109785 can dodge down. It is essential to attach the shear plate to the coupling plate with the same fasteners as the coupling bracket to which the actual coupling is attached. Such a way 5 ensures that in a collision both the shearing plate and the coupling holder are released simultaneously from the Kupplungeplatte and the coupling is no longer held by the coupling holder in a certain horizontal position. The coupling thus freed 10 thus falls down and does not collide longitudinally with components of the undercarriage or chassis. In a further embodiment of the invention it is provided to arrange a stop in the movement space of the severed shear plate, which influences the direction of movement of the shear plate. Thereby, the position of the loose shearing plate can be oriented in a collision so that it is oblique to the direction of movement of the separated clutch 20 and thus covers components of the undercarriage or chassis as a shield. Furthermore, an obliquely separated shear plate supports the vertical movement of the coupling. This is particularly advantageous since this vertical forces act on the clutch 25, which exceed the weight force many times, whereby the evasive movement of the disconnected clutch is accelerated. Furthermore, it can be ensured that the connection between the coupling plate and the coupling holder is separated directly. This is essential because the components mentioned can adhere to one another, for example because of a lacquer layer or Bostansatz. The vertical forces caused by an inclined shear plate immediately separate these adhesive joints. 16/06/2011 10:53 4 No .: R235 P.007 / 026 16.Jun.2011 10:21 051707S4601 201109785

    In a further development of the invention, the shear plate is equipped with a hook-shaped shape, which ensures a mechanical interaction with the stop. 5 Thus, the advantage can be achieved, the advantageous
    Ensuring an inclined position of the shear plate.
    It is essential to provide the connecting elements, with which the shearing plate, the coupling plate and the coupling holder 10 are connected, with a predetermined breaking point. This predetermined breaking point is to be dimensioned 2U so that the expected operating forces do not lead to a triggering of the predetermined breaking point, forces that occur in a collision, however, trigger the breaking point immediately. 15 The predetermined breaking point is to be arranged within the Verbindungeelemente so that the free mobility, in particular the clutch holder is not affected by the failure of the predetermined breaking point. It is recommended to arrange the predetermined breaking point of the connecting elements in the area of the 20 contact surfaces between the coupling plate and the coupling holder.
    As Verbindungsaelemente preferably screw can be used, since the components, 2fi in particular the coupling holder for maintenance purposes is easy to remove. Likewise, screws can be well equipped with the required breaking point at any point, for example, by a cross-sectional constriction. The sequence of operations in the event of a collision with a rolling stock equipped with a subject invention is as follows: 16/06/2011 10:54 5 Nr .: R235 P.008 / 026 16.Jun.2011 10:21 05170754601 CIC_P | 0635 P.009 / 026 ♦ · e · * a · * · 201109785 • «*« * * * * e * * * e * * e # # a * · * * *

    The clutch plate 2 is part of the undercarriage and firmly connected to this, via the clutch plate 2, the operating forces (tensile and compressive forces) which are transmitted from the clutch 30 4 are directed into the visual vehicle. The
    Clutch 4 is connected to the clutch plate 2 by means of a clutch holder 3. This coupling holder 3 allows the deflection of the coupling 4 in horizontal and 7 16/06/2011 10:54 No .: R235 P.010 / 026 16.Jun.2011 10:22 06170754601 201109785

This coupling connection may further comprise reversible or irreversible damping elements and be provided with an overload protection δ, which separates the clutch 4 from the coupling holder 3 in collisions. In the example shown, a component 10, for example a bogie longitudinal connection plate is provided at a position which the free mobility limited in the axial direction of the coupling 10. This component 10 is firmly connected to the undercarriage, thus in a collision which separates the overload protection of the clutch, in addition to the intended force path (via the deformation elements), a further, parallel force path (via the clutch 4 and 15 component 10) arise.
    FIG. 2 shows, by way of example and schematically, a coupling connection in the case of a triggered overload protection according to the prior art. A detailed representation of the coupling coupling of FIG. 1 is shown. The
    Clutch holder 3 is fastened by means of connecting elements 6 to the coupling plate 2. The coupling plate 2 comprises a recess 12 through which the coupling 4 has penetrated and is blocked on the component 10. It is 25 no escape from this position possible because the clutch 4 is still guided by the coupling holder 3 and can only perform axial movements

Also here is a component 10, 8 16/06/2011 10:55 No .: R235 P.011 / 026 16.Jun.2Dll 10:22 05170754601 C1CWP | 0635 P.012 / 026 201109785 • · · · «· * I ··· • · * · · · * * · · * * ft * ······· * which limits the axial movement possibility of the clutch 4 is provided. The clutch 4 is shown in the operating position and is connected via an upper load fuse 9 with the coupling holder 3. Other components, such as 5 joints, spring-damper elements, etc. are not shown for simplicity. Behind the coupling plate 2, a shearing plate 5 is arranged, which is connected by connecting elements 6 with the coupling plate 2 and the coupling holder 3. The coupling plate 2 has a recess 12 10, which is larger than in the example shown in FIG. 2 and extends in particular further downwards (in the direction of the track bed). The shearing plate 5 has a hook-shaped formation 8, which is designed so that it can interact with a stop 7 (for example, a bar arranged transversely to the longitudinal direction).
    4 shows, by way of example and schematically, a coupling connection according to the invention when the upper load safety device is triggered. It is shown the coupling connection of Figure 3 20, wherein in the course of a collision, the overload protection was triggered 9 and the clutch 4 has hit the shear plate 5 and this has solved by means of the predetermined breaking points of the Verbindungslemente 6. The shearing plate 5 is shown in the end position, which it occupies by 25 the interaction between the stopper 7 and the hook-shaped formation 8.
    Fig. 5 shows an example and schematically a coupling connection according to the invention when triggered 30 overload fuse, clutch fully retracted. It is shown the coupling connection of Figure 4 in the further course of the collision.

    CIC_P # 0635 P.013 / 026 could thus avoid the component 10. In this case, the coupling 4 is displaced in the recess 12 down, the coupling holder 3 further comprises the clutch 4. However, since the connecting elements 6 were separated at their predetermined breaking points 5, the coupling holder 3 could be moved vertically.

It is a section through the coupling plate 2 and the coupling holder 3 in the region of a connecting elements 6 shown. The predetermined breaking parts of each connecting element 6 is positioned so that a vertical movement of the coupling holder 3 is not hindered after the separation of this predetermined breaking point. For this purpose, it is necessary to provide the predetermined breaking point within the section of the connecting element 6 located in the bore of the coupling holder 3, in this way it is ensured that no parts of the separated connecting element 6 become caught on the bore in the coupling plate 2 and the vertical mobility of the coupling holder 3 can affect. The second, remaining part of the connecting element 6, which is not shown in Fig.6, is pulled by the movement of the shearing plate 5 in the course of the collision inevitably 25 from the holes and can the vertical

This component 10 hinders the further axial penetration of a coupling towards the center of the car, so that the coupling is centered by the shear plate 5 and the recess 12 is deflected to allow further penetration. A stop 7 ensures a safe 10 take the desired end position of the shear plate. 5
