  • the invention relates to a snow protection arrangement for a coupling area of a rail vehicle that travels in areas with snow.
  • snow can accumulate or accumulate on the rail vehicle.
  • a critical area for such snow accumulation is
  • the coupling arranged there is designed for the coupling of other rail vehicles (e.g. for coupling with a motor vehicle of a further team of rail vehicles) and is used accordingly.
  • the couplings must be pivoted horizontally and vertically in certain areas to enable the coupling process or to be able to operate in bends and points.
  • FIG. 7 shows a first embodiment of an American locomotive as a SFZ8 rail vehicle.
  • FIG. 8 shows a second embodiment of a German Inertity ICE as a rail vehicle SFZ9.
  • the rail vehicle SFZ9 is designed in the coupling area KUPB9 with a short coupling (hidden here) and with a small front opening FROE9.
  • This configuration is complex since a design with front flaps FKL9 is required in order to reduce or completely prevent the ingress of snow in the coupling area KUPB9.
  • This Ausgestal device is used in particular for high-speed trains, because 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 locomotive or rail vehicle SFZ10 of a German city train.
  • the SFZ 10 rail vehicle has a coupling area
  • a manually removable snow protection system which is designed here as an AH10 cover.
  • the cover hood AH10 is put over the coupling KUP10 and then covers it at least partially.
  • Such a cover hood AH10 is made, for example, of a strong, ie mechanically loadable, tarpaulin material, as is also used in the area of trucks to cover loads.
  • Such a snow protection system is very inexpensive, but it requires time for assembly and disassembly and manual work by operating personnel during the coupling process.
  • a coupling area KUPB11 can be seen in detail in FIG. 10, which can be filled with snow and thus clogged.
  • a coupling joint KUPG11 can also be seen, which is arranged in the coupling region KUPB11 and interacts with the coupling KUP11 from FIG.

  • the rail vehicle has one on one end face
  • Snow to be protected indentation in which a coupling of the rail vehicle is at least partially arranged.
  • a fixed enclosure at least partially includes the indentation.
  • the housing points in the direction of travel of the rail vehicle an opening from which the coupling partially protrudes in a predetermined angular position to enable a coupling process with another rail vehicle.
  • the opening of the fixed housing is permanently connected to a first sealing element.
  • a second sealing element is rotatably connected to the coupling and the second sealing element at least partially encompasses the coupling.
  • the two sealing elements at least partially overlap in the area of the opening at different angular positions of the coupling.
  • the two sealing elements are pressure-coupled to protect the opening and thus the indentation from the ingress of snow.
  • the coupling is designed such that the rail vehicle can be connected via the coupling to a correspondingly configured 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 driving around curves and switch areas with the further rail vehicle.
  • the coupling thus has respective angular positions for the coupling process and in the operation of the connected rail vehicles.
  • the indentation is at least partially covered by a fixed housing.
  • the coupling is protected in the area of the booking via the fixed housing.
  • the opening of the fixed housing is circumferentially connected with a sealing element, the first sealing element, so that the sealing element is also firm 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 a flexible rubber as a sealing element of the housing.

  • the second sealing element has a snow-tight transition to the clutch.
  • the second sealing element is rotatably connected to the coupling as a sealing element of the coupling, this connection being preferably configured as a swivel joint.
  • the rotatability of the second sealing element and the positions and shapes of the two sealing elements have the effect that, with different angular positions of the coupling, the sealing element of the coupling is always coupled to the sealing element of the housing by the action of pressure.
  • the second sealing element is preferably designed as a Hohlhuntpro fil or as a bead.
  • the two sealing elements at least partially overlap one another and lie movably against one another. Due to their respective positions, the two sealing elements are pressed together.
  • a frictional connection is preferably realized between the two sealing elements.
  • the second sealing element is preferably made of a flexible rubber.
  • the hollow chambers or beads provide additional flexibility of the sealing elements and support the desired frictional connection.
  • the second sealing element has flexible sleeves 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 functions reliably with every movement of the coupling.
  • Translatory movements of the coupled rail vehicles are recorded in the direction of the longitudinal axis of the rail vehicles by pressing in the hollow chamber profiles or the beads while sealing at the same time.
  • the hollow chamber profiles or beads slide onto one another and thus absorb these movements while sealing at the same time.
  • the arrangement according to the invention can be 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 severe winter months without the need for manual operations.

Abstract

L'invention concerne un arrangement de protection contre la neige pour une zone d'attelage d'un véhicule ferroviaire. Le véhicule ferroviaire possède, au niveau d'un côté frontal, une échancrure à protéger de la neige dans laquelle est disposé au moins partiellement un attelage du véhicule ferroviaire. Une enceinte fixe entoure au moins partiellement l'échancrure. L'enceinte comporte une ouverture dans le sens de la marche du véhicule ferroviaire, de laquelle l'attelage fait partiellement saillie dans une position angulaire prédéterminée afin de rendre possible une opération d'attelage avec un autre véhicule ferroviaire. L'ouverture de l'enceinte fixe est reliée à demeure à un premier élément d'étanchéité sur toute sa périphérie. Un deuxième élément d'étanchéité est relié à l'attelage de manière à pouvoir tourner et le deuxième élément d'étanchéité entoure au moins partiellement l'attelage. Les deux éléments d'étanchéité se chevauchent au moins partiellement dans la zone de l'ouverture à différentes positions angulaires de l'attelage. Les deux éléments d'étanchéité sont accouplés l'un à l'autre par pression afin de protéger l'ouverture contre une pénétration de la neige.
