Definitions

  • the present invention relates to an automatic train coupling, in particular for a freight wagon of a rail vehicle, according to the preamble of claim 1.
  • automatic train couplings of this type comprising a coupling head with a coupling housing and a coupling lock with a locking mechanism.
  • the coupling lock is designed as a rotary lock with a coupling eye and a frog.
  • the frog is rotatable about a main axis between a ready-to-couple position, a coupled position, and an uncoupled position.
  • the coupling eye is connected to the frog by a first end rotatable about a coupling eye axis and has a second free end.
  • the frog has a mouth for receiving a corresponding second end of a coupling eye of a matching coupling head.
  • a spring-loaded mechanism is attached to the frog.
  • the frog can be rotated from the coupled position to the uncoupled position against the force of the spring-loaded mechanism, and from the uncoupled position to the ready-to-couple position and from the ready-to-couple position to the coupled position by the force of the spring-loaded mechanism.
  • the locking device which holds the coupling lock in the appropriate position or releases it accordingly for transition to another position by rotating the frog, has a plunger which can be displaced in the coupling direction of the train coupling against a spring force and a ratchet rod which can be displaced transversely or diagonally to the coupling direction.
  • the ratchet rod is connected to the frog in an articulated manner and can be displaced by the frog when it is rotated from the coupled position to the uncoupled position into a detent position, in which the ratchet rod prevents the frog from being rotated backwards, that is, in the direction from the uncoupled position to the coupled position.
  • the plunger in turn, is movable between a first position and a second position. In the first position, in which the plunger is displaced against the spring force, the plunger blocks the latching rod in the detent position, and in the second position, in which the plunger is displaced from the first position by the spring force, the plunger releases the latching rod from the detent position.
  • This generic automatic train coupling is as follows: Two opposing coupling heads on two vehicles to be coupled together are locked together by inserting the second end of the respective coupling eye into the mouth of the frog of the other coupling head and holding it in place by rotating the frog there. This mechanically couples the two vehicles.
  • the two coupling locks are loaded exclusively by tensile forces, which are evenly distributed between both coupling eyes within the parallelogram formed by the coupling eyes and the frogs.
  • Compressive forces are transmitted by a special profile on the front of the coupling head housing.
  • the profile usually comprises a cone and a funnel, which are enclosed by a wide, particularly flat, front surface, as is advantageous in the present invention.
  • the profile can be formed by a separate front plate attached to the front of the coupling head housing.
  • the profile, together with the cone and funnel, can form sliding and centering surfaces, and in particular, determine the gripping area in terms of lateral, vertical, and angular offset. When the coupling heads meet, they center themselves and slide into each other.
  • a decoupling device rotates both coupling locks, i.e., the two frogs, against the force of the spring-loaded mechanisms until the coupling eyes slide out of the frogs' mouths.
  • the rotating frogs are designed to displace the ratchet rods sufficiently to prevent the frogs from rotating back from the uncoupled position beyond the ready-to-couple position when the vehicles are separated, by moving the ratchet rods into their locking positions.
  • the train couplings are designed so that the coupling heads or coupling locks operate alternately. For example, if a coupling lock is released with a manual or automated uncoupling mechanism by rotating its frog against the force of the spring-loaded mechanism, this rotational movement is transmitted to the opposite frog via the coupling eye, which is articulated to the frog, and the jaws of the opposite frog. Accordingly, the opposite frog transmits its rotational movement to its ratchet rod, which engages the latching position.
  • the lubrication device comprises at least one lubricant source and one or more lubricant lines connected to the lubricant source in a lubricant-conducting manner.
  • the lubricant lines can, for example, comprise passages and/or channels in components and/or flexible hose lines and/or rigid lines on components and/or between components.
  • a lubricant distributor the lubricant from the lubricant source can be distributed to various joints and movement points.
  • a lubricant channel is integrated into the main bolt and is supplied with lubricant via a lubricant line.
  • the present invention is therefore based on the object of improving a generic automatic train coupling in such a way that lubrication of at least one lubricated point in the coupling head is facilitated.
  • access to one or more lubrication points for manual lubrication, for example, via a grease nipple, is to be made easier for a service technician.
  • An automatic train coupling according to the invention in particular for a freight car of a rail vehicle, has a coupling head comprising a coupling head housing and a coupling lock with a locking mechanism.
  • the coupling lock is designed as a rotary lock with a coupling eye and a frog, wherein the frog is rotatable about a main axis between a ready-to-couple position, a coupled position, and an uncoupled position.
  • the uncoupled position can coincide with the ready-to-couple position, or, viewed from the coupled position, the uncoupled position is provided beyond the ready-to-couple position, relative to the rotational movement of the frog.
  • the coupling eye is connected to the frog at a first end so that it can rotate around a coupling eye axis, and has a second free end.
  • the second free end forms, in particular, a crossbar to achieve the eye-shaped configuration of the coupling eye.
  • the frog has a mouth configured to receive a second end of a coupling eye of a counter-symmetrical coupling head. The frog can be rotated from the coupled position to the uncoupled position against the force of a spring-loaded mechanism and, by the force of the spring-loaded mechanism, at least from the uncoupled position to the coupled position.
  • the frog can be rotated from the uncoupled position to the ready-to-couple position and from the ready-to-couple position to the coupled position by the force of the spring-loaded mechanism.
  • the cross-piece of the coupling eye is inserted into the mouth.
  • the locking mechanism of the coupling lock comprises a plunger displaceable in the coupling direction of the traction coupling against a spring force, and a ratchet bar displaceable transversely or diagonally to the coupling direction.
  • the ratchet bar is then preferably connected to the frog in an articulated manner and, upon rotation from the frog from the coupled position to the uncoupled position, can be displaced by the frog into a locking position, in which the ratchet bar blocks rotation of the frog from the uncoupled position to the coupled position.
  • the plunger blocks the ratchet rod in the locking position in a first position displaced against the spring force and releases the ratchet rod from the locking position when it is in a second position displaced by the spring force.
  • the automatic train coupling comprises a lubricating device with which lubricant can be supplied to at least one lubricated point in the coupling head, wherein the lubricating device has one or more lubricant channels in the coupling head.
  • At least one lubricant channel extends through the core.
  • the frog extends in a disc-shaped manner comparatively far radially to the main bolt and thus, with the at least one lubricant channel running inside the frog, a lubrication point for introducing lubricant can be placed radially far outwards, so that this lubrication point is easily accessible from outside the coupling head, in particular is positioned on one side of the coupling head, and starting from this lubrication point, the lubricant in the frog can be guided radially far inwards to at least one lubricated point, for example on the main bolt.
  • the at least one lubricant channel in the core extends in a radial plane perpendicular to the main axis.
  • the coupling eye has a coupling eye bolt that is rotatably mounted around the coupling eye axis in the frog, wherein the at least one lubricant channel in the frog opens into an interface between the coupling eye bolt and the frog.
  • This interface can thus be lubricated with lubricant from the lubricant channel, wherein a sliding movement occurs in this interface due to the relative rotation between the frog and the coupling eye bolt, so that the lubrication in this interface reduces wear.
  • annular channel is provided in the frog that is open to the coupling eye bolt, and at least one lubricant channel in the frog opens into the annular channel.
