    专利说明:

    The invention relates to a coupling with an electric coupling, in particular for a rail vehicle according to the preamble of claim 1.
    A mechanical vehicle coupling is disclosed in the document EP-A-2 322 403, which can be used in both passenger and freight trains and enables automatic coupling of two vehicles on both straight and winding routes. The electrical lines of the vehicles are connected or disconnected by means of corresponding electrical couplings. The plugs or sockets provided for this must be accessible to the outside during the coupling process, but they must be protected against contact, dirt, water, etc. in the uncoupled state.
    In a generic coupling arrangement according to the document EP-A-0 972 693 two coupling devices are provided, each having a coupling head which is supported on a tie rod of a pulling and pushing device which is attached to the rail vehicle via a bearing. The respective coupling head is formed from a multi-part housing. It is provided with a coupling member and the other coupling head with a corresponding recess. This coupling member is intended to engage in the recess of the other coupling head when coupling.
    Another coupling head according to the Swiss patent application No. 00805/19 is provided with a housing which has an abutment surface on the front for a flat support with an abutment surface of a coupling head to be coupled and on the rear a connection flange for attachment with a tie rod or the like. In addition, a coupling and locking mechanism is integrated in the housing. The housing is essentially produced as a one-piece pot shape, in which the abutment surface is formed on the front wall or this connection flange is formed on the rear wall. Due to its design with this compact housing, the coupling head is optimally designed to absorb the very high tensile and compressive forces that occur during the coupling process and with the coupled rail vehicles in operation, especially when accelerating or braking.
    The invention is based on the object of creating a coupling with an electrical coupling in which the control during coupling and uncoupling of the mechanical and electrical coupling is simple and safe, but these are matched to one another with optimized use of the available energy sources.
    According to the invention, this object is achieved according to the features of claim 1.
    The electric coupling is equipped with a coupling housing and a piston / cylinder unit which can be displaced for coupling or decoupling. According to the invention, the control and / or the actuation of the piston / cylinder unit takes place at least for coupling the electrical coupling by means of the compressed air of the main air line. This results in a very simple and safe coupling or uncoupling of the electrical coupling.
    Very advantageously leads from the main air line, which is passed through the coupling head, a branch line with a two-way valve arranged in this in that chamber of the piston / cylinder unit to adjust the latter when opening the two-way valve in the position of the coupled state of the electric coupling.
    Alternatively, a branch line with a two-way valve arranged in this can be guided from the main air line of the coupling head to a control valve, this control valve when the two-way valve is actuated, one or the other chamber of the piston / cylinder unit with the connection line to the separate pressure medium for coupling it and uncoupling connects or closes.
    The invention and further advantages thereof are explained in more detail below using exemplary embodiments with reference to the drawing. It shows:<tb> Fig. 1 <SEP> is a diagram of a coupling with an electric coupling and a coupling head with a section of a closing valve and a coupling element of the main air line;<tb> Fig. 2 <SEP> the scheme according to FIG. 1 with an alternative control or actuation of the electric clutch; and<tb> Fig. 3 <SEP> a side view with a partial section of the electric coupling with a fastening plate on its upper side for mounting on the coupling head.
    Fig. 1 shows schematically a coupling with a mechanical coupling head 10 and on the top, side or below this attached electric coupling 20, in which this coupling is used in particular for a rail vehicle. Automatic coupling or uncoupling of a rail vehicle with another rail vehicle can thus be achieved, this coupling preferably being suitable for freight cars.
    With the electrical coupling 20, the electrical lines of the rail vehicles are connected to each other, so that the power supply and electrical control lines to the coupled vehicles is guaranteed. In each rail vehicle, an electrical coupling 20 is positioned on the front and rear side in such a way that it can be coupled in a compatible manner to any other vehicle.
    The electrical coupling 20 is equipped with a coupling housing 21 and with a piston / cylinder unit 25 which can be displaced. Its piston 28 is rigidly held on the coupling head 10 and the cylinder 29 and with it the coupling housing 21 are movably guided on this piston 28, which is explained in more detail below with regard to FIG. 3.
    This coupling head 10 is provided with an indicated housing 10 ', which on the front side has an abutment surface 14 for a flat support with an abutment surface of a coupling head to be coupled for the coupling of two rail vehicles or the like. Further details of the locking during coupling are not shown, as these do not relate to the invention. A guide vane 16 is also indicated at the front at the abutment surface 14, which are designed for centering two heads 10 to be coupled to one another. Furthermore, at least one main air line 11 (HLL) leads through the coupling head 10, which is supplied with an existing operating pressure of air for the brakes of the rail vehicles.
    In this main air line 11 in the coupling head 10, a closing valve 30 and a connecting means 40 are contained in a manner known per se. This connecting means 40 comprises a plunger 41 adjustable in its axis, a sleeve 42 guiding this and a compression spring 43. This plunger 41 can project valve-controlled to the abutment surface 14 of the coupling head 10 and be pushed into an opening of a main air line of a coupled coupling head, not shown, so that a tight connection of the main air line between the heads is made possible.
    The closing valve 30 in the main air line 11 comprises a stationary guide sleeve 31, a closing piston 35 guided by this with a cavity 36 and a compression spring 32 arranged therein. In the closed state, the closing piston 35 is with its upper end face 35 'on an annular surface of the 90 ° angled main air line 11 sealingly. This closing piston 35 is arranged displaceably at the bottom in a cylinder chamber 34 which is connected to a two-way valve 37 via a branch line 38.
    The plunger 41 is likewise advanced when the two-way valve 37 is opened, since it is also fed via this branch line 38 and this branch 38 '.
    According to the invention, a branch line 12 with a two-way valve 13 arranged in this is led from the main air line 11 in the coupling head 10 to a control valve 19, this control valve 19 when actuating the mechanically switchable two-way valve 13 one or the other chamber 26, 27 of the piston / Cylinder unit 25 of the electrical coupling 20 connects or closes with a connection line 15 from a separate pressure medium 17 for its coupling and uncoupling. The pressure medium 17 can be contained in a pressure vessel and can likewise be connected to the main air line HLL or a main air vessel line HBL or to a separate pressure source. In the event of a pressure drop in the main air line, this pressure vessel can be used to ensure that decoupling of the electrical coupling would still be possible.
    With the supply of the control of the control valve 19 by the air pressure in the main air line 11, the already existing pressure of 3.5 to 5.0 bar can be used, which simplifies the control on the one hand and on the other hand a reliable operation is guaranteed.
    Fig. 2 shows a variant of a control of the electrical coupling 20, in which the actuation of the piston / cylinder unit 25 for displacement for coupling the electrical coupling 20 takes place according to the invention by means of the compressed air of the main air line 11.
    For this purpose, a branch line 12 leading away from the main air line 11 with a two-way valve 13 arranged in this leads directly into a first chamber 26 of the piston / cylinder unit 25 to move the latter into the coupled state when the two-way valve 13 is opened of the electrical coupling 20, while a connection line 15 to a separate pressure medium 17 leading into a second chamber 27 of the piston / cylinder unit 25 is provided for its uncoupling. This second chamber 27 is arranged in the cylinder 29 on that side on which its piston 28 is held rigidly on the coupling head with the piston rod 28 '. This connecting line 15 also contains a pressure reducing valve 22, by means of which a higher pressure difference is brought about between the two chambers 26, 27.
    In Fig. 2, a simplified variant is indicated by dash-dotted lines, in which this line 12 'shown in phantom leads directly from the main air line 11 after the closing valve 30 into the chamber 26 of the piston / cylinder unit 25, this without or with a Actuating valve. The branch line 12 with the two-way valve 13 would then only be led to the branch line 38 and pressure would be generated in the chamber 26 at the moment when the closing valve 30 was opened during coupling.
    In principle, the branch line 12 with the two-way valve 13 could be completely omitted and this line 12 'shown in dash-dotted lines also be guided into the branch line 38, which is not illustrated.
    Instead of this connecting line 15 leading into the second chamber 27 and the pressure medium 17, a compression spring 33, as indicated by dash-dotted lines, could be arranged in this chamber 27, which would permanently exert pressure on the piston 28 and thus cause a decoupling as soon as the pressure in the other chamber 26 is lowered, or when a pressure is built up in the latter chamber 26, coupling would take place.
    Fig. 3 shows a side view of the electrical coupling 20, which these plugs and / or sockets 45 in the coupling housing 21, an electrical cable 46 leading away to the rail vehicle, a support plate 44 arranged on the top with a protruding bracket 44 'for rigid support of the Piston 28, the piston / cylinder unit 25, a hinged cover 47 at the front of the plugs and / or sockets 45 for protecting them in the uncoupled state, a linkage 48 for opening and closing the cover 47 and a guide arrangement 49 for the Has clutch housing 21. A linkage 48 holding the cover 47 is provided on both sides and, in the case of the guide arrangement 49, two slide bars 51 arranged next to one another and slide elements 52 guided on these are likewise advantageously arranged.
    The invention is sufficiently demonstrated with the above embodiments. However, it could also be explained by further variants.
    The valves explained above are, unless otherwise explained, built as two-way valves which, when actuated, are brought into an open position, but are brought back into the closed position by means of spring elements. Of course, however, these valves could also be designed differently as required, for example as multi-way valves, such as 5/2-way valves, monostable, bistable, which can be pneumatically, mechanically and / or electrically actuated.
    The piston / cylinder unit (25) can also be designed as a differential piston in which the chamber 27 is permanently acted upon, for example via this compression spring 33 or by compressed air. To retract and extend the electrical coupling, only the chamber 26 is then pressurized with compressed air or vented. The differential force can be increased by using a pressure reducing valve in the feed line to chamber 27.
    The drive of the electric coupling could take place via a lever system instead of a pneumatic cylinder, the end position being in an over dead center as with a toggle lever, which would also be actuated by means of a piston / cylinder unit or the like.
    The actuation of the piston / cylinder unit for moving for the coupling of the electrical coupling could take place instead of the compressed air of the main air line by means of the compressed air of the main container air line or a separate pressure medium. A corresponding branch line would then have to lead away from this main container air line in an analogous manner.
