Definitions

  • the present invention relates to a two-leaf door system for rail vehicles.
  • the invention also relates to a rail vehicle with two-leaf door systems.
  • Entry systems for rail vehicles often include two door leaves that open or close an entry area via a sliding or pivoting / sliding movement. When the door leaves close the entry area, their main closing edges touch.
  • the main closing edge is located on the front door leaf edge in the closing direction.
  • a secondary closing edge of the door leaf is arranged at the rear in the closing direction. The main closing edge and the secondary closing edge of a door leaf extend over the entire height of a door leaf.
  • the object of the present invention to be achieved is to provide a two-leaf door system which is pressure-capable. Furthermore, this door system should have a simple structure. The problem to be solved is also to provide a rail vehicle with a double-leaf door system which is pressure-capable.
  • the rigid frame pillar is provided in the area of the first main closing edge of the first door leaf, which absorbs the forces of the pressure surges.
  • the rigid frame pillar forms a first support surface and serves as an abutment for the second door leaf.
  • the second door leaf forms a second support surface in the area of the second main closing edge. The two support surfaces are pressed against each other in the event of pressure surges and seal the vehicle interior against changes in pressure.
  • the door opening is surrounded by the sealing frame.
  • the sealing frame corresponds in principle to a sealing frame of a single-leaf door system. When the door system is closed, the two door leaves seal against the sealing surface of the sealing frame.
  • the door leaves Due to the rigid frame pillar, the door leaves can absorb the operating forces that arise without deformation of the door leaves due to pressure surges.
  • the door leaves are designed for fatigue loads above 1,200 Pa.
  • the two-leaf door system according to the invention is pressurized, as a result of which no pressure changes can occur in the vehicle interior due to pressure surges, so that passenger comfort is considerably increased.
  • the door opening and closing times of the two-leaf door system according to the invention are comparable to the door opening and closing times of single-leaf door systems.
  • the first door leaf On the first secondary closing edge and on the first transverse sides, the first door leaf has a first seal which, in the closed state of the first door leaf, rests against the sealing surface of the sealing frame.
  • a second seal is arranged on the second main closing edge, on the second secondary closing edge and on the second transverse sides.
  • a single, one-piece first seal is preferably arranged on the first secondary closing edge and on the first transverse sides of the first door leaf.
  • the first seal can be designed in three parts, for example.
  • a part of the first seal can seal the first upper transverse side, a further part the first lower transverse side and a further part the first secondary closing edge.
  • Additional sealing elements can be provided at the respective corners of the first door leaf at which the ends of the individual sealing parts meet.
  • a single circumferential one-piece second seal is advantageously arranged on the second main closing edge, the second secondary closing edge and the two second transverse sides of the second door leaf.
  • the second seal can also be designed in four parts, for example.
  • One part of the second seal can seal the second upper transverse side, another part the second lower transverse side, another part the second secondary closing edge and another part the second main closing edge.
  • Additional sealing elements can be provided at the respective corners of the second door leaf at which the ends of the individual sealing parts meet.
  • the second seal is arranged in the area of the second main closing edge in the closed state of the two-leaf door system between the two support surfaces and is preferably compressed.
  • the first seal and the second seal are advantageously designed as butterfly seals.
  • a butterfly seal has two sealing lips which, when the door system is closed, lie against the sealing frame and the first support surface.
  • the first and the second seal can also be designed differently, as long as they are suitable for sealing a double-leaf door system.
  • At least one inlet wedge is advantageously arranged on the end face of the first main closing edge.
  • An inlet keyway is arranged along the second main closing edge in the edge region of the second door leaf, in which the inlet wedge is arranged in the closed state of the door system and exerts a pressure force on the support surfaces.
  • inlet wedges it is particularly advantageous for a plurality of, very particularly advantageously, three inlet wedges to be arranged at a distance from one another along the first main closing edge.
  • several, preferably three, corresponding inlet keyways are arranged on the second main closing edge.
  • a single inlet keyway is provided which extends along the second main closing edge.
  • the inlet wedges which are spaced apart from one another, are arranged in the inlet keyway.
  • a single inlet wedge can also be arranged over the entire first main closing edge. An inlet wedge running over the entire main closing edge enables a particularly stable and thus pressure-proof locking of the door leaves.
  • a first rubber finger protection is advantageously arranged on the front side of the second door leaf along the second main closing edge in the area of the outside of the door and a second rubber finger protection in the area of one of the inside of the door.
  • the inlet keyway or the plurality of inlet keyways are arranged between the two rubber finger guards.
  • the finger protection rubbers can be made hollow, whereby they can be compressed and sensors, such as pressure sensors, can accommodate.
  • the first rubber finger protection is preferably molded onto the second seal.
  • the second seal and the first finger protection rubber thus form one component, so that assembly times are short.
  • the present invention relates to a rail vehicle whose two-leaf door systems are designed according to one of the features mentioned above. No elastic deformation occurs on the door leaves when entering tunnels or when trains meet, which generate pressure surges.
  • the first door leaf is preferably locked on the sealing frame before the second door leaf is set in motion and is locked on the first door leaf.
  • the door leaves move at an angle of approx. 45 °.
  • the locking elements on the door leaf side are inserted behind locking elements in a step bar of the door opening.
  • the closing process of the two door leaves can also take place quasi-parallel. Both door leaves are set in motion at the same time. However, the first door leaf reaches the closed position on the sealing frame before the second door leaf and is locked there. Immediately after locking the first door leaf, the second door leaf is moved into the closed position and locked on the first door leaf. A parallel closing process is also possible, whereby the duration of the closing process is shorter than with the asynchronous closing process.
  • the opening of the two door leaves can also take place asynchronously, quasi-parallel or in parallel.
  • the x-axis extends along the width of the first door leaf 20a and the second door leaf 20b and parallel to the longitudinal axis of the vehicle.
  • the y-axis extends along the height of the door leaves 20a, 20b.
  • the z-axis extends along the thickness of the door leaves 20a, 20b and parallel to the transverse axis of the vehicle.
  • the door leaves 20a, 20b have a door leaf outer surface S1 and a door leaf inner surface S2, the door leaf outer surface S1 facing outwards and the door leaf inner surface S2 facing inwards.
  • the Figure 1 shows a schematic illustration of a door opening 25 of a rail vehicle, the illustration showing an outer surface S1 of a door leaf. Passengers can get into the rail vehicle or leave it via the door opening 25.
  • the door opening 25 is surrounded by a sealing frame 22.
  • the door opening 25 can be closed via the first door leaf 20a and the second door leaf 20b.
  • FIG. 1 the door opening 25 is shown open.
  • the door opening 25 can be closed in a parallel, a quasi-parallel or an asynchronous closing process of the door leaves 20a, 20b.
  • the example shown is an asynchronous closing process in which the door opening 25 has already been closed by the first door leaf 20a.
  • the first door leaf 20a has a first main closing edge 21a at the front in the closing direction, a first secondary closing edge 50a at the rear in the closing direction, a first upper transverse side 52a and a first lower transverse side 54a.
  • the first transverse sides 52, 54a connect the first main closing edge 21a and the first secondary closing edge 50a.
  • the first door leaf 20a is locked in the area of a first main closing edge 21a by means of a central lock (not shown).
  • the second door leaf 20b then closes.
  • the second door leaf 20b forms an in Closing direction a front second main closing edge 21b, a rear second secondary closing edge 50b in the closing direction, a second upper transverse side 52b and a second lower transverse side 54b.
  • the second transverse sides 52b, 54b connect the second main closing edge 21b and the second secondary closing edge 50b.
  • the second door leaf 20b is locked on the first main closing edge 21a of the first door leaf 20a in a manner similar to a passive locking of a classic single-leaf door system.
  • the passive locking on the main closing edges 21a, 21b of both door leaves 20a, 20b is implemented by running several inlet wedges 26 of the first door leaf 20a, which are spaced apart from one another along the first main closing edge 21a, into recesses on the second main closing edge 21b of the second door leaf 20b.
  • FIG. 2 an isometric cross-sectional illustration of a portion of the locked first door leaf 20a in a lower portion of the door opening 25 is shown. Also in Figure 2 the door leaf outer surface S1 is shown.
  • a frame pillar 23 extends along the y-axis in the area of the first main closing edge 21a. The frame pillar 23 is particularly rigid and forms a first support surface 24a for the second door leaf 20b over the entire height of the first main closing edge 21a.
  • the first door leaf 20a rests against a sealing surface 36 of the sealing frame 22.
  • the first door leaf 20a has a three-sided circumferential first seal 34a.
  • the first seal 34a is arranged on the sides of the first door leaf 20a which rest against the sealing frame 22 in the closed state of the door system 20.
  • No first seal 34a is provided on the first main closing edge 21a.
  • no seal is arranged on the first support surface 24a.
  • Figure 3 shows an isometric cross-sectional representation of a partial area of the two door leaves 20a, 20b in a closed state of the door system 20, the door leaf outer surface S1 being recognizable.
  • the second door leaf 20b has a first frame groove 29, an inlet keyway 30 and a second frame groove 31.
  • the first frame groove 29, the gate keyway 30, and the second frame groove 31 are arranged parallel to each other along the z-axis from the door leaf outer surface S1 to the door leaf inner surface S2.
  • the two frame grooves 29, 31 are used to attach a finger protection rubber 27, 28, which are held in the frame grooves 29, 31 and locked along the x-axis.
  • the finger protection rubbers 27, 28 are hollow, as a result of which they are compressed and can accommodate sensors such as pressure sensors.
  • a second seal 34b is arranged on the first rubber finger protection 27.
  • the second seal 34b is designed as a butterfly seal.
  • the butterfly seal has two sealing lips 60 and is arranged on the first finger protection rubber 27 facing the vehicle interior.
  • the geometric dimensions of the inlet keyway 30 are larger than the first frame groove 29.
  • the inlet keyway 30 is pushed onto the inlet key 26, as a result of which the inlet keyway 30 and the inlet key 26 make contact.
  • the inlet wedge 26 causes a contact pressure on the first support surface 24a.
  • the second door leaf 20b forms a second support surface 24b.
  • the second support surface 24b extends in the region of the second main closing edge 21b over the height of the second door leaf 20b.
  • the first support surface 24a is pressed against the second support surface 24b.
