    description
    Rail vehicle coupling for the connection of two rail vehicles.
    Technical area
    The invention relates to a rail vehicle coupling for the connection of two rail vehicles, as well as a method for removing a spherical bearing in this rail vehicle coupling.
    State of the art
    Typically, subways and trams always run in the same train configuration and this is not changed operationally. As a result, special vehicle concepts can be used, for example so-called litter cars. These litter cars do not have their own bogies but are carried by the adjacent cars. Such a saving of expensive bogies can be realized if the allowable axle load of the track allows the load on the remaining bogies to be increased. So-called half-ash or semi-trailer vehicles have a single chassis and are carried at their other end of the car by an adjacent vehicle. Between a conventional and a litter car, a specific clutch is provided, which transmits the operating and weight forces and which ensures the required mobility for curves Kuppen- and tub runs. For this purpose, ball-and-socket joints (spherical bearings) are usually used. However, a maintenance of these joints can only be done if the
    Coupling point between a conventional car and a litter car is separated. In this case, the litter car, since it does not include a bogie, suitable to lift and support. This activity is also in a well-equipped rail vehicle workshop a comprehensive, complex and therefore expensive project. In particular, it is disadvantageous that all other (electrical, pneumatic) connections as well as the transitions between the cars are to be separated, which leads to a considerable amount of work.
    Presentation of the invention
    The invention is therefore based on the object of specifying a rail vehicle coupling for the connection of two rail vehicles, which comprises an easily exchangeable ball joint (spherical bearings) and to provide a method for removing this bearing.
    The object is achieved by a rail vehicle coupling with the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.
    According to the basic idea of the invention, a rail vehicle coupling for the connection of two rail vehicles is described which comprises a joint eye arranged for releasable connection to one of the two rail vehicles and a joint fork arranged for releasable connection to the other of the two rail vehicles and a horizontally oriented axis. On the horizontal axis, the joint eye is positioned centrally, in which the spherical bearing is embedded. The
    Spherical bearing is penetrated by the horizontal axis, which in turn is supported at its two ends by the yoke.
    According to the basic idea of the invention, a rail vehicle coupling is described for the connection of two rail vehicles which has a joint eye arranged for detachable connection to one of the two rail vehicles and a joint fork which is designed for detachable connection to the other of the two rail vehicles and a horizontally oriented axis which is connected to the joint fork is connected and which penetrates a spherical bearing connected to the joint eye, wherein the yoke comprises a fastening device for releasably securing a maintenance frame and the joint eye comprises at least one mating receptacle for the lateral alignment of the maintenance frame.
    As a result, the advantage can be achieved to be able to attach a maintenance frame to the rail vehicle coupling temporarily, which fixes the ball joint in a certain position in the fixed position and transmits all forces and moments between the rail vehicles. It is particularly advantageous if force is free when mounted maintenance frame of the spherical bearing so that it is easy to remove.
    In the mounted position, this maintenance frame connects the coupled rail vehicles firmly together, taking the same relative position to each other as without mounted maintenance frame.
    This is particularly advantageous, since in such a way the usually existing connecting lines and the car transition need not be separated. This can be a
    Spherical bearings are exchanged much faster than conventional constructions without maintenance frame.
    Exemplary invention is particularly advantageous to use as a compound of a conventional, only rollable (equipped with two chassis) rail vehicle with a rail vehicle alone not rollable. Non-rollable rail vehicles are typically designed as so-called sedan chairs (without chassis) or half-ash bags with a chassis (also called semi-trailer or trailer vehicles). The rail vehicle coupling according to the invention is suitable for the coupling of all types of litter vehicles, including half-sumps with conventional rail vehicles.
    It is particularly advantageous to design the maintenance frame and the corresponding attachment points on the yoke and the joint eye so that all weight forces of the litter carriage can be transmitted via the clutch, even with expanded spherical bearings. As a result, the advantage can be achieved during the joint replacement to make no support of the sitter car. For this purpose, the components mentioned are carried out with appropriate strength.
    In a further development of the invention, it is recommended to carry out the fastening device for releasably securing a maintenance frame in the form of at least one recess in the yoke, in each of which a sliding block can be introduced, wherein at least one internal thread is provided in the sliding block. This is particularly advantageous if the yoke and the joint eye are made of light metal, since internal threads are usually to be avoided on light metal components. An alternative embodiment comprises threaded inserts made of steel in the light metal components, to which the maintenance frame can be repeatedly screwed without risk of damage. It is possible to produce the yoke and the joint eye made of steel, but it leads to a much higher weight, but in steel components threads for the attachment of a maintenance frame can be easily provided.
    The sliding block can be made of steel, so that a sufficient power transmission through the internal thread is ensured.
    It is advantageous to provide the maintenance frame with at least one fitting pin, which is in the mounted position of the maintenance frame with the at least one fitting receptacle of the joint eye in engagement. As a result, the advantage can be achieved to be able to specify an exact defined relative position of the vehicles to one another, so that the replacement of the spherical bearing is simplified.
    The expansion of a spherical bearing is thus carried out with the following process steps:
    Parking the train of at least two rail vehicles on a straight track section.
    Optional introduction of at least one sliding block in a recess on a yoke of a
    Rail vehicle coupling on one of the rail vehicles.
    Attaching a maintenance frame to the yoke of the rail vehicle coupling by means of a screw connection. The screw can be done directly into an internal thread on the yoke or in a
    Internal threads of the introduced in the previous, optional process step nuts.
    Remove the axis penetrating the spherical bearing.
    Expansion of the sphere warehouse.
    The installation of a spherical bearing takes place in reverse order.
    In a further development of the invention, it is recommended to provide two spacers, which are designed as a hollow cylinder and which comprise the axis on both sides of the spherical bearing. By means of these spacers can at Ein- or. Exposing the axis excessive loading of the slideways, esp. The spherical cap of the Spherärlager be avoided because the inner part of the Spherärlager is supported by these spacers and thus these forces do not act on the Sphärolager during the extraction of the axis.
    To provide the spacers with an external thread and the corresponding hole in the yoke with an internal thread, so that the axial position of the spacers is adjustable relative to the yoke is particularly advantageous. In this way, the inner part of the spherical bearing can be positioned exactly in the middle and thereby be clamped without play on the axle. Thus, a positioning of the yoke in relation to the joint eye is possible, so that the longitudinal axes of the connected rail vehicles can be centered to each other. Alternatively, one of the spacer sleeves can be omitted if the axle is designed on the side of the corresponding spacer sleeve of larger diameter.

    Embodiment of the invention
    Fig.l shows an example and schematically a Zugzusammenstellung with a litter wagon. It is a train of three vehicles is shown, with a rail vehicle in litter construction 2 is coupled between two conventional rail vehicles 3. Here, a rail vehicle coupling 1 according to the invention is arranged between the rail vehicle in sedan construction 2 and the conventional rail vehicles 3 each. Such a Zugzusammenstellung still requires other components, in particular a roll support to prevent tilting of the litter wagon. Such roll support can be arranged for example in the roof area of the vehicles, but is irrelevant to the function of objective invention.
    2 shows by way of example and schematically a rail vehicle coupling. It is a rail vehicle coupling 1 shown in an oblique view, which comprises a joint eye 4 and a yoke 5, which are each designed for attachment to a car body. An axis 6 penetrates both the yoke 5 and arranged in the joint eye 4 Spherolager, which is not visible in Fig.l.
    3 shows an example and schematically a
    Rail vehicle clutch in a side view. It is a rail vehicle coupling 1, as shown in Figure 2 shown in a side view. In this case, the spherical bearing arranged in the rail vehicle coupling 1 is freely movable, i. the coupling can transmit forces in all three spatial directions, but no moments between the joint eye 4 and the yoke 5. Fig. 3 illustrates the state in which the rail vehicle coupling 1 is in ferry operation in use.
    4 shows by way of example and schematically a rail vehicle coupling in a side view with mounted maintenance frame. It is one
    Railcar coupling 1 as shown in Figure 3 shown in a side view, as it is configured for the maintenance of Spherärolagers. For this purpose, a maintenance frame 8 is releasably secured to the yoke 5 in aligned rail vehicles. For this releasable attachment a screw connection, comprising screws 13 and nuts 12 is provided in the exemplary embodiment shown, wherein the nuts 12 include internal threads for the screws 13 and are mounted in recesses in the yoke. This embodiment is particularly advantageous in jointed forks made of light metal, since no such thread must be cut in these joint forks. When mounted maintenance frame 8, the rail vehicle clutch 1 is locked, so that the vehicles are firmly connected. The weight of the rail vehicle in sedan construction 2 is transmitted via the joint eye 4 and the maintenance frame 8 to the rail vehicle in a conventional design, the spherical bearing inside the rail vehicle coupling 1 is force-free. To support the maintenance frame 8, the rail vehicle can be suitably supported in litter construction 2 on the track bed, for example by means of a jack. Thereby, the maintenance frame 8 can be made low in strength.
    5 shows by way of example and schematically a rail vehicle coupling in an oblique view from below.
    It is a rail vehicle coupling 1 as shown in the previous figures, with no maintenance frame 8 mounted. In this view, the recesses 11 for the sliding blocks 12 and the mating receptacles 13 in the joint eye 4 can be seen. The mating receptacles are designed to receive corresponding fitting pins 10 on a maintenance frame 8 and ensure exact alignment of the rail vehicle coupling 1 when the maintenance frame 8 is mounted. As a result, aligned alignment of the rail vehicles 2, 3 can be achieved, which facilitates the removal of the axle 6 and the spherical bearing 7 ,
    6 shows an example and schematically a rail vehicle coupling in an oblique view with mounted maintenance frame. It is the
    Rail vehicle coupling 1 in the same view as in Figure 5, but shown with mounted maintenance frame 8.
    7 shows by way of example and schematically a rail vehicle coupling in a sectional view with maintenance frame. It is a vertical section through the hinge eye 4 and the maintenance frame 8 a
    Rail vehicle coupling 1, as shown in Figure 6 shown. In this sectional view, in particular the engagement of the fitting pins 10 of the maintenance frame in the mating receptacles 9 of the joint eye 4 can be seen.
    8 shows by way of example and schematically a rail vehicle coupling in a sectional view through the axis. It is the rail vehicle coupling 1 shown in FIG. 7, wherein the vertical sectional plane through the fulcrum of the spherical bearing 7 is placed. When mounted maintenance frame 8, the spherical bearing 7 is free of force, the axis 6 thus unloaded and can be moved axially and removed. 8 shows further components, such as are advantageous for practical implementations of the rail vehicle coupling 1 according to the invention, for example a holder and spacers 14 for the spherical bearing 7. The spacer sleeves 14 are hollow-cylinder-like and comprise the axis 6 and extend from the spherical bearing 7 on both sides to the outside and close with the end face of the axis 6. In this case, the spacer sleeves 14 are equipped with an external thread, which are arranged with threaded bushings 15 internal threads in engagement, so that the respective axial position of the spacer sleeves 14 is adjustable. The
    Spacers 14 are thus connected via the threaded bushes 15 fixed to the yoke 5 and support the spherical bearings 7 during the extraction of the axis 6, whereby no resulting from the withdrawal of the axis 6 forces are transmitted through the sliding surfaces of Sphärolagers.
    9 shows an example and schematically a
    Rail vehicle coupling with expanded spherical bearing. The rail vehicle coupling 1 from FIG. 8 is shown in a vertical section through the pivot point of the spherical bearing 7. The axis 6 is removed and not visible in FIG. 9; the spherical bearing 7 is removed from the joint eye 4 together with its holder.
