- a disadvantage of the automatic train couplings with pneumatic distribution is that compressed air must always be available. For example, a car has been standing for three months in the cold, the air reservoir is emptied and propulsion accordingly not possible anymore.
- DE 43 10 741 shows an automatic train coupling with a coupling body and an electric clutch, which subsequently, i.e. after finishing mechanical Coupling, coupling.
- Such a coupling must be up to the compensation certain transverse play between the mechanical couplings only in the longitudinal direction be moved.
- the electric clutch known from DE 43 10 741 is designed in such a way that that the electrical coupling is released before mechanical uncoupling, so that due to the transverse movements forced by the mechanical coupling Longitudinal guide of the electric coupling is not damaged.
- a disadvantage of the line couplings or the electrical coupling according to the State of the art is that the coupling of the line elements or the electrical coupling either must be done mechanically or after completion of the mechanical Coupling process.
- the object of the invention is a centering device for receiving an electric clutch to specify an automatic train coupling with which the disadvantages of State of the art can be avoided, but in particular a safe and automated coupling of the electrical coupling simultaneously with the mechanical one Domes is enabled.
- This task is performed by an automatic train coupling with the characteristics of Claim 1 solved.
- the centering device has a height and self-centering device, so that the electrical couplings arranged in the receiving devices two consecutive train couplings are automatically centered without the two electrical couplings in contact with each other during the centering process come.
- the height and side centering is done with the help of a baffle reached, the impact surface having a first, a second and a third section has and the baffles of the first and third sections offset in parallel run to each other and the baffles of the second section with the Boundary surface of the first or third section enclose an angle 0 ⁇ ⁇ 90 °.
- angle ⁇ the impact surface of the second section with that of the first or third section, preferably in Range is 30 ⁇ ⁇ 60 °.
- Angle ⁇ 45 °.
- the baffle is part of a baffle frame, which is guided by a guide frame of the centering device.
- a Sufficient mobility of the impact surface and protection of the electric coupling against Damage to the coupling process is achieved in that the centering device comprises a handlebar arrangement with a pre-pressing device, which is configured in this way is that the baffle is in a position ready for coupling before coupling Lead is held in front of the coupling level of the electric clutch.
- This lead is particularly preferably 10 to 20 cm.
- a delay device is advantageously provided which is configured in this way is that they have run-up forces that occur when the impact surfaces of the electric clutch collide arise, delay.
- a further damping can be in a special embodiment of the electric clutch at high run-up forces can be achieved with the help of a friction lever, which in the Version is stored and rubs against the impact frame when the version is deflected.
- the locking and releasing device at least one projection and includes at least one undercut.
- the locking and release device further one Has catch hooks.
- the catch hook is used for a multiple when the clutch is iced up After the ice layer has defrosted, it can be snapped into place when it is coupled to enable automatic train coupling.
- the invention also provides a Fully automatic train coupling available, which is characterized in that it comprises a centering device of the type described above.
- an embodiment of the invention is particularly preferred in which the centering device, which receives the electrical coupling in the manner described above, is arranged at an angle ⁇ with respect to the carriage axis. Preferably this angle lies in the range 20 ⁇ ⁇ 40 °.
- the invention also provides a clutch and a release method for the electric clutch an automatic train coupling with a centering device, as described above, on.
- two coupling heads become automatic Pull coupling run onto each other, creating the baffles the centering device in the area of the second compared to the first and third Section arranged at an angle ⁇ to the system with each other come and the two baffles in the area of the second section on each other slide so that those picked up by the receiving device of the centering device Electrical couplings are height-centered.
- the height centering and the run-up become the two centering devices rejected by the catch hooks so that the locking and Release device can not snap into place. Is due to a certain feed point the overrun forces are reached, the catch hooks are not caught by the counter clutch rejected more.
- the catch hooks and the projections of the locking and releasing device then snap into the undercuts of the respective counter coupling, whereby the transverse displacement and the hooking in the counter coupling are completed is.
- the invention also adjusts Method for separating a coupled electric clutch from an automatic Towing coupling with a centering device, as described above, is available. If the automatic pull coupling is disconnected, the catch hook and the hook the centering device from the undercuts of the respective counter coupling unthreaded. The baffle frame is then pushed through the first pushing device pushed forward so that the baffles are in the position ready for coupling with a lead in front of the coupling level of the electrical coupling, which is thereby protected from damage during the coupling process.

- 3b shows the run-up of the clutches.
- the baffles of the clutch and the counter clutch 100 touch in the middle Area 34 of the baffles 30.
- the receiving devices 40 of the electric clutch are kept at a distance D, so that the electrical coupling in the receiving device 40 do not touch and there is no damage when coupling can.
- the receiving device 40 By sliding the impact surfaces in the central area 34, the receiving device 40 height centered. The clutches do not lock because the Catch arms 52 reject the respective counter coupling.
- the closing movement of the coupling head and the electric coupling are the same and allow a high coupling and separation speed.
- baffle frame The impact on the baffle frame will possibly freeze and knocked on snow and coarse dirt.
- the storage of the baffle frames in the guide frame is advantageously designed in such a way that despite pull-push movements, rearing up, lowering and angle formation when cornering the automatic pull clutch, the electric clutch like Described here as a rigid structure and remains closed.
- the storage of the electric clutch is also designed such that a coupled Electric clutch, which is, for example, iced up, can also be separated can, for example by positive locking.
