Definitions
- 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
- Embodiments are the subject of subordinate claims.
- the yoke comprises a fastening device for releasably securing a maintenance frame and the hinge eye comprises at least one fitting receptacle for the lateral alignment of the maintenance frame.
- Rail vehicle coupling to be able to fix a maintenance frame temporarily, which fixes the ball joint in a certain position in a 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.
- this maintenance frame connects the coupled rail vehicles firmly together, taking the same relative position to each other as without mounted maintenance frame.
- Wagon crossing need not be disconnected. This can be a Spherical bearings are exchanged much faster than conventional constructions without maintenance frame.
- Non-rolling rail vehicles are typically called
- the rail vehicle coupling according to the invention is for the coupling of all types of litter cars, too
- Execute maintenance frame in the form of at least one recess in the yoke, in each of which a sliding block
- 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 via the internal thread
- Rail vehicle coupling on one of the rail vehicles.
- Spherical bearings are positioned exactly in the center and thereby clamped free of play on the axle.
- 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.
- one of the spacer sleeves can be omitted if the axle is designed on the side of the corresponding spacer sleeve of larger diameter.
- Fig.7 Rail vehicle coupling section with maintenance frame Fig.8 Rail vehicle coupling section through axis.
- Fig.l shows an example and schematically a
- Rail vehicles 3 is coupled. It is between the rail vehicle in sedan construction 2 and the conventional rail vehicles 3 each according to the invention
- a joint eye 4 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
- Rail vehicle clutch in a side view. It is a rail vehicle coupling 1, as shown in Figure 2 shown in a side view. It is in the
- Railcar coupling 1 arranged spherical bearings freely movable, i.
- the clutch can power in all three
- FIG. 3 illustrates the state in which the rail vehicle coupling 1 is in driving operation in use.
- Spherical bearing is configured. This is in alignment
- a maintenance frame 8 releasably attached to the yoke 5.
- a screw comprising bolts 13 and 12 nuts provided, the nuts 12 include internal threads for the screws 13 and are mounted in recesses in the yoke.
- This embodiment is in particular at joint forks
- the spherical bearing inside the rail vehicle coupling 1 is free of force.
- 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.
- Fig. 5 shows by way of example and schematically a
- 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 1 in the same view as in Figure 5, but shown with mounted maintenance frame 8.
- 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
- Implementations of the rail vehicle coupling 1 according to the invention are advantageous, for example, a holder and
- the spacers 14 are designed like a hollow cylinder and include 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 from.
- 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 extraction of the axis 6 forces over the
- Rail vehicle coupling with expanded spherical bearing It is the rail vehicle coupling 1 of FIG. 8 in a
