Definitions

  • the invention relates to a device for covering the line mouth at the front end of a line coupling, which is accommodated in the coupling head of an automatic coupling for rail vehicles, with a longitudinally movable, flexible band, which has a portion serving as a protective flap, which in the uncoupled position of the coupling head in front of the
  • the line mouth can be adjusted to cover it and can be removed during coupling processes from the line mouth to release it, the band being guided over at least one deflection point deflecting its longitudinal direction.
  • the section of the band which can be adjusted in front of the line mouth as a protective flap in the uncoupled state requires special guidance and / or stiffening in order to be able to cover the line mouth reliably; Special springs and / or rods are required for this guidance or stiffening, which results in a complex and sensitive mechanism.
  • the invention has for its object to design a device of the type mentioned in such a way that it avoids the shortcomings of the known devices, is particularly simple and requires little effort.
  • the band is provided, at least in the region of its section serving as a protective flap, with an elastic transverse corrugation running transversely to its longitudinal direction, which is flattened in band parts located in the region of deflection points, and in that the serving as a protective flap Section of the tape is stable in front of the line mouth due to inherent rigidity.
  • the sufficient inherent rigidity of the band is achieved by the transverse corrugation, which ensures that the band is held securely in front of the pipe mouth, even without special guiding and / or stiffening devices.
  • Fig.l is a dash-dotted line coupling l is shown, which belongs to an automatic coupling of the usual type, not shown, and whose mouth 2, with which it can be coupled to a mating coupling, not shown, faces away from the viewer.
  • a section 3 of a flexible band 4 in front of the mouth 2, the section 3 covers rougeei the mouth 2 and thus serves as a protective flap for this.
  • the deflection point 5 has several bolts 6 between which the band 4 is passed and of a longitudinal extent in its section 3 in which extends perpendicular to the axial direction of the line coupling 1 a longitudinal direction running approximately parallel to and to the side of the line coupling 1 is deflected.
  • the rear end of the band 4 is cut off and not shown; at this end one intervenes Actuating device by means of which the band can be moved in its longitudinal direction in accordance with the direction of the double arrow 7.
  • the actuating device can have actuating levers which, when a mating clutch starts, pull the band 4 backwards against the spring force from the position shown until the section 3 slides off the mouth 2 and thus releases the latter for coupling.
  • the actuating levers When uncoupling, the actuating levers are released from the counter clutch, and the spring force mentioned can advance the band 4 again into the position shown.
  • the actuator can thus receive training as shown in the already mentioned DE-OS 34 35 779.
  • section 3 can be guided solely through the deflection point 5 in front of the mouth 2 and that no further guiding and / or stiffening devices are required for the section 3; section 3 is thus held in front of the mouth 2 by its inherent rigidity.
  • this In order to give the band 4 the required inherent rigidity, this must be designed at least in the region of its section 3 serving as a protective flap, as described below:
  • the band 4 is provided, at least in the region of its section 3, with a transverse corrugation which is elastic or molded into the band 4; the transverse corrugation is illustrated in FIG. 2 by the reference number 8 by reference to the locations of its maximum, lateral and in the longitudinal direction of the band 4 shaped formations.
  • the transverse corrugation 8 is formed from the band 4, ie the band 4 is flattened in the region of the deflection point 5 by the bolts 6, as is indicated in FIG. 1; as a result, the longitudinal direction of the band 4 in the deflection point 5 can be deflected easily. Outside the deflection point 5, the band 4 automatically resumes the transverse corrugation 8 due to its elasticity.
  • the transverse corrugation 8 runs between lateral delimitation planes 9 and 10, and the lateral ones Edges ll and l2 of the band 4 are located between the delimitation planes 9 and l0 approximately in their central plane l3, the distances a and b of the edges ll and l2 to the delimitation planes 9 and l0 are thus approximately the same.
  • the arches of the transverse corrugation 8 are designated in FIG.
  • edges 11 and 12 of the band 4 lie in arc sections 14 and 16 directed away from the mouth 2. This design prevents the edges ll or l2 from coming into contact with the mouth 2 and damaging the sealing ring.
  • the band 4 has the transverse corrugation 8 at least in the region of its section 3 which can be moved as a cover flap in front of the mouth 2.
  • care must be taken to ensure that the band 4 has a reduced inherent rigidity in its area facing away from the section, that is to say it could buckle against the mouth 2 without any special precautions in particular when the section 3 is pushed forward.
  • the band 4 can also be provided with the transverse corrugation 4 over its entire length, as a result of which it obtains an inherent stiffness in all of its regions outside the deflection point 5, which it automatically stretches and thus also holds suitable for transmitting thrust forces.
  • the band 4 can also be deflected several times, it is only essential that the deflection point 5, which is located on the side of the mouth 2, directs and guides the section 3 in front of the mouth 2, the section 3 thus no further guidance or stiffening is required.
  • the deflection point 5 may josei or the like instead of the bolt 6 with rollers. ver be seen, whereby the longitudinal displacement of the band 4 is facilitated.
  • the device for covering the line mouth (2) at the front end of a line coupling (l) has a longitudinally movable, flexible band (4), a section (3) of the band (4) serving as a protective flap in the uncoupled state in front of the line mouth (2 ) is adjustable.
  • the band (4) is provided at least in its section (3) with a transverse corrugation (8), by means of which it can be held in front of the mouth (2) with inherent rigidity. To deflect the longitudinal direction of the belt (4), the transverse corrugation (8) is flattened in a deflection point (5).
