Definitions
- the present invention relates generally to the adaptation of couplings in particular of track-guided vehicles, such as rail vehicles.
- the invention relates according to a first aspect of an adapter part for adapting a coupling head of a first type with a coupling head of a second type.
- the coupling head of the second type may be different from the coupling head of the first type.
- this relates to a corresponding coupling head with such an adapter part for providing a transitional coupling and a method for adapting a coupling head of a first type to a coupling head of a second type.
- Transition couplings are used on vehicles with different types of couplings or coupling heights, eg. B. when maneuvering and towing.
- special designs have traditionally been used so far in order to be able to releasably connect (couple) corresponding coupling heads of different coupling types.
- a common approach is to provide a so-called intermediate piece, which is connectable on the one hand to the coupling head of a first type and on the other hand to a coupling head of a second type.
- Such an intermediate piece is described for example in the publication DE 26 32 571 A1.
- FIG. 1a shows diagrammatically a first coupling head 1 of the "Janney" type and a corresponding counter-coupling head of the same design, each in a ready-to-connect state Molding horn 3, 3 'and pocket 4, 4' and a joint jaw 6, 6 'which can be rotated horizontally on a vertical bolt 5, 5'.
- FIG. 1a are the two coupling heads 1, each shown in a ready-coupling state.
- the joint jaws 6, 6 'of the respective clutches engage in the coupling jaw 8, 8' of the counter-coupling and thereby pivot the joint jaw 6, 6 'of the counter-coupling in the horizontal plane about the corresponding vertical bolt 5, 5 ', with which the joint jaw 6, 6' with the corresponding coupling head body 2, 2 'is pivotally mounted.
- each coupling head 1 is rotated by the action of the counter coupling head into the closed position in which it is located in the interior of the coupling head body 2, 2' parts of a bolt system, as latch bolt and bolt lifter are locked (see FIG lc).
