Definitions

the invention relates to a rail vehicle that runs in snowy areas.
the coupling arranged there is designed for coupling other rail vehicles (e.g. for coupling to a traction vehicle of another rail vehicle combination) and is used accordingly.
couplings must be able to pivot horizontally and vertically in certain areas in order to enable the coupling process or to be able to operate in curves and switch areas.
5 and 6 each show a rail vehicle SFZ6, SFZ7 with couplings KUP6, KUP7 and with coupling areas KUPB6, KUPB7 that are completely snowed in or iced over.
FIG 7 shows a first embodiment of an American locomotive as a rail vehicle SFZ8.
FIG. 8 shows a second embodiment of a German Intercity ICE as a rail vehicle SFZ9.
the rail vehicle SFZ9 is designed in the coupling area KUPB9 with a short coupling (concealed here) and with a small front opening FROE9.
This configuration is complex, since a construction with front flaps FKL9 is required in order to reduce or entirely prevent the penetration of snow in the coupling area KUPB9.
This configuration is used in particular in high-speed trains, since here the front flap construction offers advantages in terms of snow and also in terms of aerodynamics.
FIG 9 shows a third embodiment of a traction vehicle or rail vehicle SFZ10 of a German city railway.
the rail vehicle SFZ 10 has a manually removable snow protection system in the coupling area KUPB10, which is designed here as a cover hood AH10.
the cover hood AH10 is slipped over the coupling KUP10 and then covers it at least partially.
Such a cover AH10 is, for example, made of a strong, ie mechanically resilient, tarpaulin material, as is also used in trucks to cover loads.
Such a snow protection system is very cost-effective, but requires time and manual labor for assembly and disassembly by operating personnel during the coupling process.
a clutch area KUPB11 can be seen in detail, which can be filled with snow and thus clogged. You can also see a coupling joint KUPG11, which is arranged in the coupling area KUPB11 and is connected to the coupling KUP11 11 works together.
the front flap module provides a coupling shaft, a coupling device accommodated in the coupling shaft and at least one front flap which can be moved using front flap kinematics and can at least partially cover the coupling shaft.
the front hatch module is provided with a covering device arranged on the coupling shaft and having a covering which is detachably fastened to the coupling shaft on the one hand and to the coupling device on the other hand.
the invention relates to a rail vehicle having the features of claim 1.
the coupling is designed in such a way that the rail vehicle can be connected via the coupling to a correspondingly designed coupling of another rail vehicle.
the coupling is preferably movably mounted within the indentation, so that the coupling can be pivoted horizontally and vertically in a predetermined angular range for the purpose of the coupling process or for the purpose of negotiating curves and switch areas with the other rail vehicle.
the coupling thus has respective angular positions for the coupling process and during operation of the connected rail vehicles.
the indentation is at least partially surrounded by a fixed housing.
the coupling is protected in the indentation area by the fixed housing.
the opening of the fixed housing is firmly connected circumferentially to a sealing element, the first sealing element, so that the sealing element is also fixed or rigid via the connection.
the first sealing element has a snow-tight transition to the housing.
the first sealing element is preferably made of flexible rubber.
the sealing element of the housing is preferably designed as a hollow chamber profile or as a bead.
the coupling is connected to a second sealing element that at least partially surrounds the coupling.
the second sealing element has a snow-tight transition to the clutch.
the second sealing element is rotatably connected to the coupling, this connection preferably being designed as a swivel joint.
the rotatability of the second sealing element and the positions and shapes of the two sealing elements ensure that the sealing element of the coupling is always coupled to the sealing element of the housing when the coupling is in different angular positions.
the second sealing element is preferably designed as a hollow chamber profile or as a bead.
the two sealing elements at least partially overlap and are movably in contact with one another.
the two sealing elements are pressed against one another by their respective positions.
a frictional connection is preferably implemented between the two sealing elements.
the second sealing element is preferably made of a flexible rubber.
the second sealing element has flexible collars which are arranged in the area around the coupling and additionally seal this area.
These flexible cuffs are preferably made of rubber.
the two sealing elements seal the opening against snow, which works reliably with every movement of the coupling.
Translational movements of the coupled rail vehicles are absorbed in the direction of the longitudinal axis of the rail vehicles by pressing in the hollow chamber profiles or the beads with simultaneous sealing.
the hollow chamber profiles or beads slide on top of each other and thus absorb these movements while at the same time sealing.
the arrangement according to the invention can be both implemented and retrofitted at low cost and with little effort.
the arrangement according to the invention ensures that the operational readiness of rail vehicles is increased in the harsh winter months without requiring any manual intervention.
the arrangement according to the invention reduces downtimes of rail vehicles that are caused by couplings blocked by snow.
FIG 1 shows a first detailed view of the arrangement according to the invention.
a coupling area KUPB of a rail vehicle SFZ is shown.
the rail vehicle SFZ has on its front side an indentation EINE that is to be protected from snow and in which a coupling KUP of the rail vehicle SFZ is at least partially arranged.
a fixed enclosure EINH at least partially encompasses the indentation EINE.
the housing EINH has an opening OFF in the direction of travel of the rail vehicle SFZ, from which the coupling KUP partially protrudes in a predetermined angular position in order to enable a coupling process with another rail vehicle.
the opening OFF of the fixed housing EINH is firmly connected all the way around to a first sealing element DIE1.
the first sealing element DIE1 is designed as a flexible hollow chamber profile.
the size of the OFF opening is dimensioned in such a way that the KUP clutch can carry out all movements arising from operation.
the housing EINH is permanently connected to the front of the rail vehicle SFZ and cannot move relative to the rail vehicle.
the OFF opening, together with the surrounding sealing element DIE1, is also dimensioned in such a way that the KUP coupling can carry out all the necessary movements during operation.
FIG 2 shows with partial reference to FIG 1 a second detailed view of the arrangement according to the invention.
a second sealing element DIE2 is rotatably connected to the clutch KUP.
the second sealing element DIE2 at least partially encompasses the clutch KUP.
the second sealing element DIE2 is designed as a flexible hollow chamber profile.
the second sealing element DIE2 is connected to the clutch KUP by a rotary joint DRG.
the second sealing element DIE2 has flexible collars FMS, which are arranged in the area around the clutch KUP and additionally seal the transition to the clutch KUP.
the flexible sleeves FMS have a frame FMSR all around, which is used to connect them to the hollow chamber profile.
a coupling joint KUPG via which the coupling KUP is fastened in the indentation EINE of the rail vehicle SFZ via a joint, can also be seen.
this joint see also the coupling joint KUPG11 of 10 ) it is possible that the coupling KUP assumes different angular positions for the execution of the coupling process and while driving connected rail vehicles.
the rotatably movable second sealing element DIE2 causes it to repeatedly align itself with the first sealing element DIE1 when the clutch KUP rotates about a vertical axis.
the two sealing elements DIE1, DIE2 at least partially overlap in the area of the opening OFF with different angular positions of the clutch KUP.
the two sealing elements DIE1, DIE2 are coupled to one another by pressure and thereby protect the opening OFF from snow penetrating.
the rotatably movable second sealing element DIE2 causes it to repeatedly align itself with the first sealing element DIE1 when the clutch KUP rotates about a vertical axis, while at the same time the ability to seal is retained.
FIG 4 shows with reference to 1 to 3 an advantageous development of the arrangement according to the invention.
This embodiment addresses the case where two rail vehicles, which are in a narrow curve of track to one another, are coupled to one another.
the rotary joint DRG is slidably mounted along the longitudinal axis of the clutch KUP.
a compression or tension spring FED holds the swivel joint DRG in position and limits the compressive or pressing force of the two sealing elements DIE1, DIE2.
the two sealing elements DIE1, DIE2 are coupled to one another, in particular when the second sealing element DIE2 is in the compressed state.
