    Abstract

    A catching device for a shunting coupling has a catching body with an end stop, a right-hand side lateral stop, and a left-hand side lateral stop that together form a holding body with an inner region delimited on three sides and an open side. The open side can be closed by a lock and the open side is dimensioned such that a specified shunting coupling can be moved into the inner region through the open side. The catching device has at least one elastic and/or elastically mounted stop element on one of the stops. There is also described a rail vehicle with such a catching device and also a method for locking a shunting coupling.

    Description

    [0035] The invention will be explained once again in more detail below with reference to the attached drawings using exemplary embodiments. In this case, the same components have been provided with identical reference numerals in the various figures. The drawings are generally not true to scale and in the drawings:

    [0036] FIG. 1 shows a rail vehicle having a shunt coupling in a catching device according to the prior art,

    [0037] FIG. 2 shows a catching device according to the prior art,

    [0038] FIG. 3 shows an exemplary embodiment of a catching device according to the invention,

    [0039] FIG. 4 shows a shunt coupling in a preferred catching device according to FIG. 3, and

    [0040] FIG. 5 schematically shows the course of a method according to the invention.

    [0041] FIG. 1 shows a rail vehicle 1, here the front section of a shunting locomotive, having a shunt coupling 2 in a catching device 3 according to the prior art. The shunt coupling 2 is in the park position here, i.e. tilted upward through 90 in comparison with the shunt position. In this park position, two shunting locomotives can also be coupled together without the shunt couplings 2 of the shunting locomotives bumping into each other during travel. As can be seen, the shunt coupling 2 is tilted in a somewhat inclined manner with respect to the side of the locomotive (on the right in the figure). It can be clearly seen that the shunt coupling 2 has a certain amount of play on the other side of the catching device 3, and therefore it could also be tilted in an inclined manner to the other side. This happens if the rail vehicle with the shunt coupling 2 in the park position were to travel around a bend.

    [0042] FIG. 2 shows a catching device 3 according to the prior art. Here, the catching device 10 has a catching body 11 which is composed of steel, has an end stop 12 on the locomotive side (to the back left) and has a side stop 13 on either side, so that an angled U-shaped profile with an inner region B is created. In order to prevent the shunt coupling 2 from tilting out in the park position (see FIG. 1), a lock 14 in the form of a bolt and a chain is arranged (for security) at a distance from the end stop 12 between the two side stops 13. For better insertion of a shunt coupling 2 into the inner region B, the ends of the side stops 13 are formed as oblique guides 19 which form a funnel. A portion of the catching body 11, which is designed in the form of a fastening 18, can be seen on the left, this fastening serving to attach the catching device 3 to a rail vehicle 1.

    [0043] FIG. 3 shows an exemplary embodiment of a catching device 10 according to the invention. This catching device looks similar to the catching device 3 according to the prior art and also has the components shown in FIG. 2, but comprises further components which securely hold a shunt coupling in the park position and reduce the play of the shunt coupling to a minimum.

    [0044] For this purpose, the catching device according to the invention comprises a stop element 15b on the end stop 12, the stop element here being provided with a spring 16 and a plate (e.g. composed of plastic, e.g. rubber) as the buffer element 5, and further stop elements 15a, which can be manufactured here e.g. as buffer elements 5 composed of rubber, on the two side stops 13. The stop elements 15a on the side stops 13 ensure that a shunt coupling 2 in the inner region B, that is to say in the park position (also see FIG. 4), cannot tilt to the left and right, but rather is always held upright.

    [0045] The stop element 15b on the end stop 12 not only ensures that a shunt coupling is held in a positively locking manner, but also has a further, highly advantageous function. This can be derived from FIG. 4.

    [0046] FIG. 4 shows a shunt coupling 2 in a park position in a preferred catching device 10 according to FIG. 3. As can be seen in FIG. 4, the stop element 15b on the end stop 12 is now shifted backward since it is pushed backward (in the direction of the fastening 18) by the shunt coupling. As a result, the shunt coupling 2 is not only pressed against the lock 14, which ensures good holding, but the shunt coupling 2 is also pushed forward by the springs 16 (see FIG. 3) after the lock 14 has opened, and therefore the shunt coupling no longer has to be moved out of the park position manually.

    [0047] For interference-free movement of the stop element 15b on the end stop 12, two guide elements 17, wherein the screws on which the springs 16 are guided can also be considered to be guide elements 17.

    [0048] The method according to the invention was used in order to reach this position.

    [0049] FIG. 5 schematically shows the course of a method according to the invention for latching the shunt coupling 2 in a catching device 10 as shown in FIG. 4.

    [0050] The shunt coupling 2 is pushed from a shunt position A to a park position B by means of a lifting cylinder 4, the shunt coupling being moved into the inner region of the catching device 10 (bent arrow). Just before the park position is reached (indicated in dashed lines), it strikes against the stop element 15b on the end stop 12 (also see FIG. 3) and pushes the stop element against a spring force of its elastic mounting with the shunt coupling 2 backward (straight arrow). The lock 14 of the open side is then closed (see closed lock 14 of FIG. 3), so that the shunt coupling 2 is pushed against the lock 14 by the spring force of the elastically mounted stop element 15b.

    [0051] Finally, it is pointed out once again that the embodiments described above in detail and the method are merely exemplary embodiments that can be modified by a person skilled in the art in a wide variety of ways without departing from the field of the invention. In addition, the use of the indefinite article a or an does not preclude the features in question from also being existent multiple times.

    [0052] Similarly, the term unit does not preclude the components in question consisting of a plurality of interacting subcomponents that, if need be, may also be distributed in space.
